1 Summary This technical report has been prepared by Micromine Consulting Services (MCS, a division
of Micromine Pty Ltd) for Terra Firma Resources Inc. (TFR). It is intended to disclose the
exploration activities undertaken so far, describe the nature of the geology and mineralisation,
and make recommendations on the implementation of further exploration programs.
The Mallawa Prospect (Mallawa) lies within mining permit 124/KPPSP/IV/2010 and TFR
currently holds the rights to explore within this licence.
The Mallawa Prospect is located within the South Celebes Arm (active island arc system) and
along the south-western axis of the Walanae Fault Zone (WFZ). The regional geology is
typical of this environment and therefore contains highly deformed marine sediments,
metamorphic rocks and ultramafic rocks. These types of environments are known to be
favourable for the emplacement of porphyry type deposits and the intrusion of mineralised
magmas. The local geology predominantly contains terrestrial sediments and intrusive rocks;
however there is some minor interbedded limestone.
A number of alteration types have been observed at Mallawa and some of these are typical of
Porphyry type mineralisation. These include Propylitic alteration, Potassic alteration and
Phyllic alteration. The samples collected so far indicate that the mineralisation is contained
within an andesite that has in-filled one of the major structural features. Samples were
collected in areas showing abundant copper minerals where younger faults cut this andesite. A
number of gossanous zones have been observed, as well as float material containing
chalcopyrite. In addition to chalcopyrite, a number of the hand samples collected also
contained covelite and minor malachite.
Mr. Johannes Erasmus, associate MCS geologist, and Mr Achmad Ramdhani of MCS were
accompanied by Mr. I.N. Soeriaatmadja, Mr. M.G. Buchanan (both of TFR) as well as a
Senior Geologist from the Indonesian Mines Department during a visit to the site from the 4th
to the 6th of May, 2011. Mr. Erasmus is the Qualified Person (QP) for the project. In order to
ensure the results of the exploration program are compliant with National Instrument (NI) 43-
101, MCS has made a number of recommendations on the procedures to be followed.
The conceptual model being tested during the exploration program is that of a large porphyry
copper-gold system. A number of samples had been collected and assayed so far and some of
these have returned significant results. The objective of the most recent field trip was to take a
new set of samples to confirm the positive grades of the first round of sampling. Two of the
earlier high value samples were re-sampled and a number of new samples have also been
collected and submitted for analysis.
MCS has reviewed the TFR work program which includes geological, structural and alteration
mapping as well as ground magnetic and IP geophysical surveys to facilitate the selection of
target areas. This will be followed by a more detailed sampling grid of pit/trench sampling,
and then by drilling. The field mapping and sampling will be carried out by local geologists
under the supervision of Mr. Andri Subandrio, TFR Senior Geologist; with regular reviews of
the procedures by the QP. MCS will assist in the creation of mapping and logging templates
that may be used for all data collection activities.
The proposed TFR exploration work program will include geological, structural and alteration
mapping as well as ground magnetic and IP geophysical surveys. While this work is being
undertaken, geochemical samples will be collected over the different alteration zones to
determine their geochemical and mineralogical profile. This will be followed by a more
detailed sampling grid of pit/trench sampling and then by drilling. Regional geological data as
well as historic and current sampling results will be transferred onto a working base map and
the accuracy of the earlier mapping will be checked. All currency figures are Canadian dollars.

The total for phase 1 and phase 2 exploration over a period of 2 years is Canadian dollars,
CD$1,186,970.
The results of the sample assays and the observations made in the field indicate that the
Mallawa Prospect has been subject to varying degrees of alteration and mineralisation. The
island arc terrane that characterises the area is another encouraging sign of the potential for
mineralisation in the area. This leads the QP to conclude that the area is conducive to the
formation of porphyry systems.

2 Introduction This technical report has been prepared by Micromine Consulting Services (MCS) for Terra
Firma Resources Inc. (TFR). It is intended to disclose the exploration activities undertaken so
far, describe the nature of the geology and mineralisation, and make recommendations on the
implementation of the exploration program.
Mr. Johannes Erasmus is the appointed QP for the project and inspected the site from the 4th
to the 6th of May 2011, accompanied by Mr. Achmad Ramdhani of MCS, Mr. I.N.
Soeriaatmadja, the TFR Country Consultant Manager, Mr. M.G. Buchanan, the Logistics
Manager of TFR as well as senior geologists from the Indonesian Mines Department. Mr.
Erasmus is independent of each of TFR, Pt. Mutiara Surya Mallawa (Mutiara) and Tirta
Winata (Tirta). TFR has a memorandum of understanding (MOU) with both of these
companies in relation to the Mallawa project. This MOU will be discussed in detail in Section
4.2 (Exploration Agreement).
The data contained in this report was sourced from the results of analytical testing, field
observations and geology Feasibility Study (this is a geology study and is not a feasibility
study as defined in the National Instrument 43-101 standards of disclosure for mineral projects)
previously completed in the area by the local government authorities. The Feasibility Study
(this is a geology study and is not a feasibility study as defined in the National Instrument 43-
101 standards of disclosure for mineral projects) was authored by M.S Mutawakkil and it
analysed the suitability of the area for road construction materials. Other information was
sourced through verbal communications with the local geologists and from an unpublished
report written by Mr. Andri Subandrio, Senior Lecturer at the Applied Geology Research
Division, Institut Teknologi Bandung (The Institute of Technology, Bandung City).
The requirements during public disclosure according to NI 43-101 are very specific. They
have the intention of providing readers with transparency on how the technical results have
been derived. The purpose of the initial site visit was for the QP to review the planned
exploration and sampling programs and to suggest adjustments to the proposed procedures.
This will ensure that future data collection, storage and interpretation methods are compliant
with NI43-101 guideline requirements.
3 Reliance on Other Experts Much of the current knowledge of the local geology of the project is based on a report in
Indonesian language by Mr. Y. Mutawakkil, dated January 4th, 2010, referred to as the
Feasibility Study (this is a geology study and is not a feasibility study as defined in the
National Instrument 43-101 standards of disclosure for mineral projects).
In contracting MCS for the project, the following deliverables were set for the MCS geologist
in the scope of works:
Travel to the project site to verify the work completed so far and to recommend
procedures for future exploration activities;
Design the next stages of exploration with the TFR geologists; and
Act as the QP to sign off press releases related to the project.
Information on the local geology of the area such as the observed alteration and mineralisation
has been sourced from Mr. Andri Subandrio. This information is in the report sections
covering local geology, alteration and mineralisation. Mr. Andri Subandrio is Senior Lecturer
at the Applied Geology Research Division, Institut Teknologi Bandung, he is a geologist.
Both Mr. Y. Mutawakkil and Mr. Andri Subandrio are non-qualified persons as defined by the
NI43-101 guidelines.
This information has been sourced both in the form of verbal communication and from an
unpublished report written by Mr. Andri Subandrio on the petrography of the rock samples.
The samples collected on the property by TFR geologists were analysed by Intertek
8
Laboratories in Jakarta. Intertek is accredited with Komite Akreditasi Nasional (KAN), which
is the Indonesian body responsible for laboratory standards. This allows Intertek to meet ISO
17025; General requirements for the competence of testing and calibration laboratories.
The information relating to the mineral title on the property was sourced from a company
press release titled “Terra Firma Signs MOU for Gold and Copper Property in South Sulawesi,
Indonesia”, dated April 19, 2011. This information was used in Section 4.2 (Exploration
Agreement).
The information relating to the environmental obligations in Section 4.3 (Obligations) was
sourced from the Indonesian Ministry of Environment’s document titled Overview of the EIA
(translated from Indonesian: Sekilas Tentang Amdal).
4 Property Description and Location
4.1 Location and Area
The Mallawa Project is located in South Sulawesi, Indonesia. The Malawa Prospect currently
is an 800 Ha mining permit located approximately three hours northeast of Makasar, The
permit is approximately 20 km north of the Bone Highway which is a major highway
connecting Makassar to Bone and other communities, Figure 4-1 and Figure 4-2 show a map
of the project location.
The mining permit number of Mallawa is 124/KPPSP/IV/2010 and it covers an area of 800 ha.
Figure 4-3 shows the location of the permit boundary. The origin of the permit boundary in
UTM coordinates (zone 50) is 821,713mE, and 9,463,958mN. For the mining permit the
boundaries are surveyed by the Indonesian mines department before the release of the IUP.
The method used is that of geodetic GPS with an accuracy of less than 0.5m. IUP is the
abbreviation for “Izin Usaha Pertambangan” which is what the mining permit is called in
Indonesia. The translation to English is mining permit.

4.2 Exploration Agreement
On April 19th, 2011, TFR entered a memorandum of understanding (MOU) with Pt. Mutiara
Surya Mallawa (“Mutiara”) and Tirta Winata (“Tirta”) under which the Company has the
option to acquire 75% of the issued and outstanding shares of Mutiara. Mutiara is an
Indonesian mineral exploration company that holds the mineral exploration license of
Mallawa. In addition, Mutiara is expected to acquire an additional 10,000 hectares of
prospective lands (the "Additional Properties") located within the 25 kilometre radius "area of
interest" defined in the MOU.
In exchange for Mutiara and Tirta entering into the MOU, TFR is required to pay an aggregate
of US$100,000 to the shareholders of Mutiara, US$25,000 of which was paid on execution of
the MOU and US$75,000 of which is payable within 60 days following acceptance of this
NI43-101 report on the Mallawa Property.
The MOU states subject to approval of the MOU by the TSX Venture Exchange, the parties
will enter into an option agreement (the Option Agreement) granting TFR an option to acquire
75% of the issued and outstanding shares of Mutiara. TFR is required to pay an additional
US$100,000 and issue 100,000 common shares to Mutiara's shareholders on execution of the
Option Agreement.
Under the Option Agreement, to successfully exercise the option to acquire 75% of the
outstanding shares of Mutiara, Terra Firma will be required to:
Pay an additional US$200,000 to Mutiara's shareholders within 18 months of the
approval of the MOU by the TSX Venture Exchange;
issue a further 200,000 common shares to Mutiara's shareholders on the later of the
date on which Terra Firma exercises the option and the date which is 120 days
following execution of the Option Agreement;
issue a further 200,000 common shares to Mutiara’s shareholders on the later of the
date on which Terra Firma exercises the option and the date which is 18 months
following execution of the Option Agreement; and
fund US$1.75 million in exploration expenditures on the Mallawa Property and the
Additional Properties, including at least US$250,000 in expenditures in the first year
of the Option Agreement.
The entering into of the MOU and the Option Agreement and the payments of cash (other than
the initial US$25,000 payment) and issuances of shares there under are subject to the approval
of the TSX Venture Exchange. All shares issuable under the transaction will be subject to a
four month hold period.
4.3 Obligations
Mutiara is an Indonesian mineral exploration company that holds the mineral exploration
license of Mallawa. TFR currently has no obligations for the property at the time when this
report was released, all obligations are for Mutiara. Mutiara is required to produce monthly,
quarterly and yearly exploration reports for the Mallawa project.
In addition to this, Mutiara is required to submit an environmental report every six months.
This requirement is associated with the Indonesian Ministry of Environment’s UKL-UPL,
which is an abbreviation in Indonesian translating to “Environmental Management Efforts and
Environmental Monitoring Efforts”.
The only additional permitting that may be required to undertake the exploration activities is a
heavy vehicle permit. This may be required when completing the diamond drilling activities
that are proposed over the next two years. This permit has not been obtained so far.
According to information supplied by TFR, TFR has no obligations under the MOU at this
time.

5 Accessibility, Climate, Local Resources, Infrastructure and Physiography
5.1 Climate and Physiography
The climate at Mallawa is mainly affected by the extent of rainfall rather than the temperature.
The wet season in South Sulawesi occurs between October and March, while the dry season
occurs between April and September (Gunawan et al.). Temperatures vary to a lesser degree,
with minimums and maximums of approximately 23°and 31° respectively (Sulawesi Weather
and Climate). The high tropical rain during the wet season supports the rainforest vegetation.
Agricultural activities are mainly the cultivation of rice and cacao beans.
The region can be divided into two morphologies. The first is a planar area with low
undulating hills and the second the Wavy Hills area with medium sized hills. The Planar area
of generally undulating low hills stretches from the east to the west, approximately 50% of the
area including the villages of Jampue, Toceppa and Bulubulu where rice and other plantations
are cultivated. Wavy Hills generally occupies the northern and southern parts, again
approximately 50% of the area. Generally the slope angles of the hills are between 10° to 30°.
5.2 Access
The access route to Mallawa is shown in Figure 5-1. Macassar is the closest airport to the
project site and there is also a major port with the capacity to handle containers and the
importation of major mining equipment. Access to the property is along the sealed road that
links Makassar and Bone and then along smaller surfaced narrow roads. The project area is
located in a typical island environment with high contrasting elevations but most areas are
accessible by narrow surfaced roads, parts of which are in a poor to moderate condition but
access with 2-wheel drive vehicles is possible. Many tracks that should be accessible by four
wheel drive vehicles were observed, as well as some logging roads which may provide access
to future drill sites.
Figure 5-1: The access route to the project site.
13
5.3 Local Resources and Infrastructure
Other mining activities on Sulawesi include limestone for cement manufacture and small
amounts of high sulphur coal used in the cement manufacturing. The closest power lines to
the property are approximately 12 Km away, Figure 5-2, high voltage power lines are pink.
The towns and cities of Makassar, Maros, Sungguminasa, and Takalar (Mamminasata) are in
the general area and may be a source of labour and also have intentions to open a connected
rail network by 2013. Some current employees of PT Terra Mineral Resources have been
sourced from local towns nearby the project site.
Aside from road access the infrastructure at the project site is very limited. There are some
residential dwellings on the property where the locals live. These homes are not connected to
any power source. The TFR base camp, which is a couple of kilometres from the property
boundary, is on the power grid.
Figure 5-2: Proximity of power lines to the project site.
6 History
6.1 Exploration History Summary
There was no ownership of the property prior to Mutiara. Mutiara first obtained the mineral
licence (IUP) on December 23rd, of 2008. IUP is the abbreviation for “Izin Usaha
Pertambangan” which is what the mining permit is called in Indonesia. The translation to
English is mining permit. The current licence (IUP) is Valid until April 30, 2030. The IUP is
able to be extended an additional 10 years, twice, for a total of an additional 20 years,
potentially allowing the IUP to be held until 2050.
Apart from the limited work performed by the government authorities in compiling the
feasibility study (this is a geology study and is not a feasibility study as defined in the
National Instrument 43-101 standards of disclosure for mineral projects), no other exploration
has been undertaken on the property. The geology feasibility Study (this is a geology study
and is not a feasibility study as defined in the National Instrument 43-101 standards of
disclosure for mineral projects) refers to earlier work by institutions that analysed the regional
resource availability for road building materials, including sand, crusher stone, coal and
marble. As Mallawa is an early stage exploration project, no previous resource estimates have
14
been completed and no mining studies have been completed. No previous production has
occurred at the site.
7 Geological Setting and Mineralisation
7.1 Regional Geology
The Mallawa Prospect is situated in the South Celebes Arm (Active Island Arc System) and
along the south-western axis of the Walanae Fault Zone (WFZ). It is underlain by the mélange,
metamorphic and ultramafic complexes of Triassic-Cretaceous ages. A mélange is a
metamorphic rock formation created from materials scraped off the top of a downward
moving tectonic plate in a subduction zone. They consist of intensely deformed marine
sediments and ocean-floor basalts and are characterized by the lack of regular strata, the
inclusion of fragments and blocks of various rock types, and the presence of minerals that
form only under high pressure and low temperature conditions. These Mesozoic complexes
are intruded and covered by Tertiary volcanic units and sedimentary rocks.
According to the local geologists, Mallawa has a favourable tectonic and structural position
for the emplacement of porphyry type deposits, especially in the western part. It is bounded by
major strike slip faults. This type of tectonic activity can create pull-apart basins which are
zones that provide high-permeability conduits for the emplacement of mineralized magmas to
shallow crustal levels (Appendix 2).
7.1.1 Stratigraphy
According to the Feasibility Study (this is a geology study and is not a feasibility study as
defined in the National Instrument 43-101 standards of disclosure for mineral projects), the
stratigraphy is based on the Geological Map Sheet Pangkajene, South Sulawesi, 1982. The
lithostratigraphy can be divided into five units:
7.1.1.1 Balangbaru Formation
This unit is a sedimentary unit consisting of alternating sandstone with silt-claystone and
black shale and occasional pebble-sized conglomerate. These Late Cretaceous rocks are
resting unconformably on the bedrock complex (metamorphic) and occupy the western part of
the Tocceppa area and covers less than 10% of the area. This unit is crushed by rocks of the
Mallawa Formation.
7.1.1.2 Mallawa Formation
This unit is composed of sandstone, arkose, siltstone, claystone, marl and conglomerate with
layers or lenses of coal and limestone. This unconformable formation is Early Eocene to
Paleocene in age. It covers approximately 5% of the area north-west of Matampa Pole
Mallawa.
7.1.1.3 Tonasa Formation
The Tonasa Formation consists of calcarenite and thick limestone containing abundant
foraminifera fossils and volcanic materials. These Eocene-Middle Miocene aged rocks can be
found around Matampapole and covers approximately 65% of the area.
7.1.1.4 Granodiorite
Granodiorite intrudes into the limestones and they are Miocene-Early Tonasa in age (Sukamto,
1982) and cover approximately 15% of the area in Matampapole and surroundings. The
granodiorite is light grey with primary minerals of quartz, biotite, oligioclase and alkali-
feldspar at the base which has been partly altered into propylite and argillite.
7.1.1.5 Basal
The basal unit is a dark grey and greenish-black intrusive rock in the form of dykes, sills and
stocks. The texture is porphyritic, with phenocrysts of pyroxene roughly 1cm in size. The
15
mafic rock is around 7.5 million years old, or Late Miocene to Late Pliocene. Solution from
the acidic magma has entered into the cracks or on the fault zone to form quartz veins, vein
calcite and sulphide veins.
7.1.2 Structural Geology
The interpretation and determination of geological structures in the area is the result of
reconstructing a combination of field data and the interpretation of topographic maps. Much of
the structural information was sourced from the Feasibility Study (this is a geology study and
is not a feasibility study as defined in the National Instrument 43-101 standards of disclosure
for mineral projects). Two main structures were noted:
7.1.2.1 Slump Structures
The Feasibility Study (this is a geology study and is not a feasibility study as defined in the
National Instrument 43-101 standards of disclosure for mineral projects) defines slump
structures where no or very little shifting has taken place. These types of rock fracture can
occur due to the cooling process at the time of formation of igneous rock, or a further
development of the structure due to forces acting on these rocks. Prominent structures located
in this region are open shear zones, indicated by cracks partly filled by quartz veins.
7.1.2.2 Fault Structure
Two types of faults are reported in the Matampapole area; strike slip and normal faults. There
is a major north-striking normal fault in the centre of the area of investigation. Overall fault
structures that dominate the area are controlled by tectonic compression from the northwest to
the southeast.
7.2 Local Geology
The Mallawa Formation is composed of non-marine sedimentary rocks, including
conglomerate, sandstone, claystone and coal. There are also interbedded marine sediments of
limestone belonging to the Tonasa Formation. Numerous intrusives are evident ranging from
basalt granodiorite, syenite, dolerite and diorite. The intrusive units have the same relative age
of the Early to Late Miocene volcanics. There also may be younger volcanic and intrusive
rocks on the Mallawa concession but only precise age dating would confirm this. The
alteration zone coincides with a circular structure in the northern part of Bukit Maraja that is
bounded on the south by a reverse fault which appears to have been formed by an intrusive
event along the WFZ. The alteration zone of Mallawa is cut by an extensive network of
altered and sheared dykes and late stage breccias.
7.3 Alteration
A number of zones of alteration have been identified by Mr. Andri Subandrio. In particular,
volcanic and intrusive rocks that are fresh to propylitically altered have been observed at the
highway at Mallawa. These are in sharp contact with a lower potassic alteration zone (PAZ),
characterized by light pink to milky white K-feldspar alteration with biotite veins, red
hematite clay and patchy zones of white gypsum. Below the PAZ zone is a central core of
bright white coloured rock exposed in the bottom of a ravine which is composed of quartz,
sericite, pyrite and kaolinite. This zone is related to the Phyllic alteration zone characteristic of
porphyry style alteration (pers. comm A. Subandrio). In some samples, K-feldspar veining is
evident which could be a remnant of an earlier Potassic zone telescoped by later destructive
alteration events. Within the alteration where leaching has occurred, mineralization is
predictably low due to acid destruction. However anomalous copper values of 0.01-7.53% Cu
have been recorded associated with the copper minerals chalcopyrite, covelite and malachite.
7.4 Mineralisation
During the recent MCS site visit, it was observed that one of the area’s major structural
features, presumed to be a fault, is filled by an andesite intrusion, striking north-south. The
andesite unit has an apparent thickness ranging from 10m to 15m, but exposure is often
limited by overburden. Two of the higher grading samples taken in February of 2011 were
16
collected where younger faults, showing the same strike, cut the andesite. At both sites,
significant copper mineralisation was observed and re-sampled at the time of the May 2011
field visit. The apparent width of the mineralised zones within the andesite was approximately
4m at MLW05.
Continuity of the andesite between observation points could not be confirmed due to the
topography but there is a high probability of extension. The continuation of the mineralised
zone from one observation and sample position to the next is less certain. Suitable outcrops
are restricted to the narrow river valleys due to the deep weathering and steep topography. As
a result, defining geological continuity through surface observations may be very difficult.
According to the TFR documents (Mallawa Porphyry Copper-Gold and Related Deposit
Exploration Target) numerous occurrences of copper gossans were found within the alteration
zone. These are normally associated with heavily sheared and altered rocks.
The mineralisation is disseminated through the silicate groundmass. Pyrite is the dominant
sulphide mineral and this is often replaced by chalcopyrite, arsenopyrite, covellite or bornite.
Minor galena and sphalerite also occurs within the mineralisation. When observed under
microscope, the sulphide crystals are mainly subhedral and it appears that they have been
corroded both on their edges and within the crystals. Figure 7-1 shows a photograph of a
polished section for sample MLW-5A (Appendix 1).
Figure 7-1: Polished section of MLW-5A (bo=bornite, chp=chalcopyrite, py=pyrite).
8 Deposit Types The geological model being tested at Mallawa is a disseminated porphyry style of
mineralisation. There are a number of typical geological characteristics typical to porphyry
systems that aid the exploration for mineralisation. The systems commonly occur at plate
boundaries and are usually centred on magmatic intrusions. Bands of alteration often emanate
from the central pluton, starting from a barren zone near the intrusion and progressing through
to sodic-calcic, “potassic, chlorite-sericite, sericitic, to advanced argillic” (Sillitoe 2010). The
mineralisation is often associated with the potassic zone of alteration, occurring within aplitic
veins and disseminated throughout the adjacent wall rock.
Porphyry systems are classified into five groups, according to the dominant contained metal;
porphyry Au, porphyry Cu, porphyry Mo, porphyry Sn and porphyry W (Seedorff et al 2005).
There are three alteration configurations that commonly occur within all five classes. The first
of these configurations can be broken down further into two sub-types. The configurations are
shown in Figure 8-1 and they can vary according to the spatial position of alteration around
the pluton.
17
Figure 8-1: The different alteration configurations in mineralised porphyry systems (Seerdorf et al 2005).
TFR will aim to use the conceptual model as a guide for the generation of targets. In particular,
the alteration assemblages can be used as a directional indicator to focus exploration efforts.
9 Exploration
9.1 Exploration Results
Two sampling campaigns were conducted within the concession; one in February 2011 and
another in May 2011. During the field trip conducted on February 26, 2011, 19 samples were
collected from five locations along the Mallawa Creek and these were submitted to the
laboratory for analysis. MCS was not part of that field trip and cannot comment on the
sampling QA/QC. The Sampling was carried out by local labourers led by TFR Senior
geologist Mr. Andri Subandrio. Figure 9-1 shows the sample locations. The samples were
hammered off the surface outcrops in the various locations along the creek.
18
Figure 9-1: Location of the samples collected in February and May 2011.
The assay results of the samples collected in February are shown in Table 9-1. The most
significant of these include MLW2A, MLW05A and MLW5D. MLW2A was taken from a
calc-silicate altered granodiorite that contains chalcopyrite, pyrite and covellite and it returned
grades of 1.22ppm Au and 5.22% Cu (Subandrio 2011). The sulphide minerals at location
MLW2 are shown in Figure 9-2.
MLW05A was sampled from a garnet skarn, with the predominant opaque mineral being
pyrite, followed by chalcopyrite, galena and sphalerite (Subandrio 2011). Sample location
MLW5 is shown in Figure 9-3. Photographs of the alteration at this site are shown in Figure
9-4, Figure 9-5 and Figure 9-6. The significant results at this location included a copper grade
of 7.33% from sample MLW5D and a copper grade of 1.08% for sample MLW05A.

The second round of sampling was undertaken during the MCS QP site visit from the 4th to the
6th of May 2011. The samples were taken as rock chip samples and put in plastic bags. Each
sample was triple bagged in an effort to prevent the samples from breaking out and being
contaminated. A total of 17 samples were submitted to Intertek Laboratories in Jakarta for
analysis. Table 9-2 shows the assay results for the samples collected. The most significant
results were received from samples ML-2D, ML-3A, ML-3C and ML-5A. ML-2D returned a
result of 0.95ppm for Au and 5.94% for Cu. ML-5A returned the highest Cu concentration,
with a value of 7.53%.
The elevated gold and copper values at ML5 correlate well with the results received during the
February sampling campaign in the same location, particularly MLW2. The anomalous copper
values at sample location ML3 have confirmed the results of the February location of MLW5.
No significant results were received from the new sample locations.

9.2 Interpretation of Exploration Results
The assay results from both sampling campaigns indicate that mineralisation occurs within the
tenement. The copper mineralisation is associated with disseminated pyrite and chalcopyrite
minerals within both granodiorite and garnet skarn host rocks. The alteration and
mineralisation of the sampled rocks indicate that the area has been subjected to hydrothermal
alteration. Confidence in the assay results is strengthened by the similarity between the two
sampling campaigns, where significant results were received at the same sample locations.
10 Drilling Mallawa is an early stage exploration project, no drilling has been conducted by TFR on the
concession and no drilling was completed by previous owners.
11 Sample Preparation, Analyses and Security
11.1 Sampling
The samples were collected as rock chip samples from exposures underlying a thin amount of
overburden. The overburden was scraped away and rock chip samples were taken from the
host rock and placed into thin plastic bags. These plastic bags were then labelled and sent to
the Intertek Laboratory.
There is the minor possibility that the samples could break out of these bags, leading to
contamination between them. Recommendations have been given to TFR by the QPs to ensure
that all samples collected in the future are triple bagged and that sample tags are placed on two
of the bags (Appendix 5). Due to the potential for contamination, the first batch of assay
results should only be used as an indication of potential mineralisation. No splitting was
undertaken to reduce the size of the samples or take duplicate samples.
MCS was not present during the first phase of the sampling program in February of 2011.
11.2 Analytical Method
Intertek Laboratories in Jakarta were used to analyse all the samples collected at Mallawa. The
laboratory is independent of TFR and MCS. No aspect of the sample preparation was
conducted by an employee, officer, director, or associate of MCS or TFR.
With regards to sample preparation, the samples submitted were mostly <2Kg, so the entire
sample was crushed and pulverised to 95% passing 200 mesh (-75um). The assay split of
200-250g was then grab sampled. The sample was then pulverised prior to final analysis.
Table 11-1 shows the methods used to analyse the samples. The first method was a 50g fire
assay with an atomic absorption spectrometry (AAS) finish. This was used for the gold
analysis. A gravimetric finish was used for gold grades greater than 50ppm. The second
analytical method used was a two acid geochemical digest with an AAS finish. Elements that
are in ore grade range received a triple acid geochemical digest. The acids used in this digest
included HCl, HClO4 and HNO3. The analysis of the mercury was completed using a
25
sulphuric and nitric acid digest with a cold vapour AAS finish. The final method used was x-
ray fluorescence (XRF) for the molybdenum.

11.3 Blanks
Blanks were inserted by the analytical laboratory as part of its own QAQC program. Of all the
blanks inserted, none returned elevated grades. Charts of the blank results are shown in the
appendix 3.
11.4 Standards
Fifteen types of standards were submitted by the laboratory as part of its own internal QAQC
program. None of the actual results for the standards exceed the action limits, so the accuracy
of the analysis for all three batches is within acceptable limits. Charts of the standard results
are shown in the appendix 3.
11.5 Duplicates
No field duplicates were collected at the point of sampling. Lab repeats were inserted by the
laboratory to analyse the reproducibility of the AAS instrument. All the results indicate a very
strong positive correlation between the original and duplicate results. Scatter plots of the lab
repeats are shown in the appendix 3.
11.6 Laboratory Inspection
No inspection of the laboratory has been completed to date. Intertek is accredited with Komite
Akreditasi Nasional (KAN), which is the Indonesian body responsible for laboratory standards.
This allows Intertek to meet ISO 17025; General requirements for the competence of testing
and calibration laboratories. The certification of the laboratory is presented in the appendix 4.
26
12 Data Verification
The assay results for the samples collected in February were provided to MCS by both
Intertek and TFR. Both of these datasets were identical. The MCS field trip undertaken from
the 4th to the 6th of May confirmed the presence of mineralisation at the sample locations.
Further samples were collected to confirm the previous assay results and additional samples
were taken from new areas. The location of the samples collected in May are also shown in
Figure 9-1, they have the prefix MI. This batch of samples was delivered to the assay
laboratory; all results are shown in Table 9-2.
The sampling procedures of the TFR geologists were not observed by the QPs in February
because the sampling was completed when the QP was not on site. As a result, no comments
on the validity of the sampling can be made. The QP was able to verify the location of the
samples during the site visit in May.
Data captured in the future will be monitored through regular site visits. MCS will verify that
the captured data is collected in a consistent manner on the prescribed templates and then
entered correctly into the database. Datasets provided to MCS will be regularly checked for
errors and if any are observed, these will be corrected by the company geologist with the
assistance from the QP.
13 Mineral Processing and Metallurgical Testing Due to the early development stage of exploration of this project, no mineral processing and
metallurgical testing work has been requested or performed on the samples from the Mallawa
project.
14 Mineral Resource Estimates Mallawa is an early stage exploration project and no attempt has been made to estimate a
Mineral Resource.
15 Mineral reserve Estimates Mallawa is an early stage exploration project and no attempt has been made to estimate a
Mineral Reserve.
16 Mining methods Mallawa is an early stage exploration project; no mining study has been conducted for this
project.
17 Recovery methods Mallawa is an early stage exploration project; no processing study has been conducted for this
project.
27
18 Project infrastructure Mallawa is an early stage exploration project; no infrastructure exists for this project other
than rudimentary access roads.
19 Market studies and contracts Mallawa is an early stage exploration project, no market study has been conducted for this
project and there are no contracts in place related to mineral sales.
20 Environmental Studies, Permitting and Social or Community Impact
TFR do not currently have any environmental permits applied for or approved. Neither do
TFR have any formal agreements in place with the local government or community. Mallawa
is an early stage exploration project; there are no mine related plans for waste and tailings
disposal, site monitoring, and water management; and no mine closure permits, arrangements
or plans of any kind.
21 Capital and Operating Costs Mallawa is an early stage exploration project; there is no production at the project site, so
there has been no determination of capital and operating costs.
22 Economic Analysis Mallawa is an early stage exploration project, there is no production at the project site, so
there has been no economic analysis conducted.
23 Adjacent Properties According to TFR personnel, no base metal or gold concessions by other exploration
companies join onto the TFR concession. The technical report states that its qualified person
has been unable to verify the information and that the information is not necessarily indicative
of the mineralization on the property that is the subject of the technical report”
24 Other Relevant Data and Information There is no additional relevant data that can supplement the information provided throughout
this report.
28
25 Interpretation and Conclusions Based on the assay results from reconnaissance sampling and the geological observations
made during both site visits, there is good potential for mineralisation on the concession.
Island Arc environments are particularly conducive to the formation of porphyry systems.
This is due to the culmination of recent volcanic activity and the presence of numerous faults
in such environments. A number of key geological traits of porphyry systems have been
observed within the concession area. In particular, the porphyritic granodiorite, the occurrence
of sulphide mineralisation and characteristic alteration assemblages are all indications that the
area could fit the geological model being applied.
In addition to the geological observations, the assay results of the samples taken on the
concession have confirmed that there are anomalous concentrations of gold and copper. The
first round of sampling in February produced significant results from samples containing
chalcopyrite, covellite, pyrite and minor malachite. These results were confirmed and verified
on site by the QP in May of 2011 when a second round of sampling was completed. The assay
results for the May samples confirmed the presence of mineralisation at the February sample
locations.
Now that anomalies have been identified on the concession, it will be necessary to conduct a
detailed mapping and sampling program to characterise the nature of the geology. Effort
should be made to determine whether the spatial location of the alteration is typical of
porphyry systems and therefore can be used as a guide to exploration. The use of detailed field
mapping and geophysical techniques may generate more targets over which further
geochemical sampling and drilling can be conducted.
29
26 Recommendations Before any further work is completed, it is essential that a team of experienced geologists be
appointed. Currently the only geologist working for TFR is Mr. Subandrio and as he has other
commitments as well. He will be using his comprehensive knowledge of the geological and
mineralisation environment to guide a group of local geologists on the mapping and sampling.
This work will have to be regularly supervised to ensure the results are valid and useful. MCS
should also visit the site on a regular basis to ensure the compliance to the prescribed
procedures.
MCS will assist in creating a geological mapping and logging template that should be used
during data collection. This should be the minimum standard used by field geologists for all
activities; including field observations, logging core and logging reverse circulation (RC) drill
cuttings. Data from hard copies of these templates should be captured electronically into a
database and the hard copy should be filed in a safe manner for at least seven years.
The proposed TFR exploration budget is shown in Table 26-1. The work program will include
geological, structural and alteration mapping as well as ground magnetic and IP geophysical
surveys. While this work is being undertaken, geochemical samples will be collected over the
different alteration zones to determine their geochemical and mineralogical profile. This will
be followed by a more detailed sampling grid of pit/trench sampling and then by drilling.
Regional geological data as well as historic and current sampling results will be transferred
onto a working base map and the accuracy of the earlier mapping will be checked. All
currency figures are Canadian dollars.

There are a number of key steps and processes that MCS recommends to ensure the
exploration program is run as efficiently and effectively as possible. As a first preparatory
stage, a base map should be prepared that will form the basis for the initial field work. This
should be followed by establishing a base reference line from which all measurements will be
taken. Before the field crews are dispatched into the field, a base camp should be established
where a secure sampling and sample storage facility must be erected. Sample security and
integrity is of the utmost importance and access to this facility must be restricted to a limited
number of persons. Communication at the base camp is essential and if the internet
connectivity is not strong enough using conventional cellphone networks, it is suggested that a
satellite system be installed. Data must be sent through a secure connection to the data
management team at MCS.
It is the recommendation of the QP that the geophysical surveys should be shifted to Phase 1
of the program to assist in locating areas of high potential that may require additional
sampling programs prior to drilling. The initial geophysical traverses need to be done on the
areas with the high sample grades. The strike extensions and lateral continuity of these areas
should be investigated as a high priority by running parallel traverses ever further from the
sample positions in both directions. Starting with a broad geophysical program and generating
smaller and smaller targets from this will be the best process to achieve this.
The commencement of drilling should be contingent on delineation of significant zones of
mineralisation during phase one. Where drill access is not possible due to the steep slopes, a
man-portable drill rig may be necessary.
Where there is any uncertainty in the exploration procedures, it will be necessary to consult
the QP so that NI43-101 compliance can be maintained. When the time comes to disclose the
exploration results to the market, the QP needs to be able to verify that every effort has been
made to avoid technical errors. A robust procedure for exploration work will give the reader a
higher degree of confidence and thus give any reported results greater integrity. The Company
will need to implement an internal QA/QC protocol (blanks, standards and duplicates),
particularly during the drilling phase. Not only rely on internal lab controls.
Following a systematic process during exploration will be the quickest way of finding
economic mineralisation. Starting with a broad geophysical program and generating smaller
and smaller targets from this will be the best process to achieve this. Given the requirements
for NI43-101 disclosure, it is critically important that the procedures detailed above are
followed. This will ensure that sufficient data is captured on the samples, that the samples are
representative and that the QAQC program has been able to detect and prevent any analytical
errors.

Sample No. MLW-02A, 02B & 02D
MEGASCOPIC CHARACTERISTICS
Rock name: Calc-silicate altered and sericitized Granodiorite
Nature of Sample: Small rock chip
Minerals Visible: Calcite, quartz, sericite, muscovite, chlorite minor biotite, hornblende
feldspar and chalcopyrite, covelite and pyrite.
Texture: Possibly relic phaneritic and porphyritic.
Colour: Creamy white-pale green.
Grain Size: Medium grained.
Other Comments: This strongly mineralized (chalcopyrite and pyrite) rock appears under
a binocular microscope to be strongly or pervasively metasomatically
altered, fractured and quartz carbonate veined, possibly porphyritic,
intermediate igneous intrusive with granodioritic norm. Primary
silicate minerals appear to be rare as residual grains.
MICROSCOPIC CHARACTERISTICS
Constituents: (Percent visual estimate)
60% Calcite, quartz and sericite (muscovite), representing products of
silicic, CO2 metasomatic and K-metasomatic alteration processes,
occur in about equal abundance as fine interlocking aggregates that in
places exhibit the relic porphyritic fabric of a diorite, possibly
granodiorite porphyry, as suggested by the rare residual andesine
present and chloritized prismatic biotite. Primary quartz is absent.
Quartz and calcite also filled irregular microfractures. Sericite
pseudomorphs after tabular and lath shaped andesine
microphenocrysts are also represented. Epidote present scarcely.
30% Chlorite and epidote of metasomatic origin occurs as tabular and
prismatic pseudomorphs after primary biotite and hornblende grains
and clusters as well as rare microphenocrysts. Residual hornblende
and biotite present as microveinlets cross cut the sericitized K-
Feldspar.
10% Opaques occur as scattered, discrete, subhedral and euhedral
grains and clusters that appear to be predominantly composed of
primary chalcopyrite, pyrite and covelite as the anhedral form and
yellow metallic lustre suggest.
Texture: Relic porphyritic and granular. Metasomatic Alteration: CO2
metasomatic, sericitic, silicic, and chloritic
Petrogenesis: A strongly microfractured and pyritized, sillicified, sericitized,
carbonatized and chloritized, diorite microporphyry.
Remarks: The relic igneous, plus the presence of residual andesine and
chloritized biotite and hornblende, suggest that the protolith was a
granodiorite porhyry. Metasomatic alteration was almost pervasive
and selective. The oxide and sulphide opaque phase present can only
be positively identified in reflected light.
ROCK NAME: Strongly microfractured chloritized, silicified, sericitized of
granodiorite porphyry
38
Various images of sample MLW‐02 show granodiorite that sericitized, CO2 metasomatized
and chloritized and groundmass Hornblende and biotite laths are partly altered to chlorite and secondary quartz, sometime associated with opaque minerals which mostly consist of base
metal sulfide. Note: bi = biotite, ca = calcite,ch = chlorite, ep = epidote, Kf = K‐feldspar,ho =
hornblende, om = opaque mineral, pl = plagioclase, py = pyrite,qz = quartz, sc = sericite
39
Pyrite (white) shows bright reflectance and porous crystals disseminated in silica groundmass of altered materials. Chalcopyrite (yellow) shows faint reflectance differences (upper right) due
to compositional variations. It encloses fine‐ galena and arsenopyrite crystals (dark grey
grey). Chalcopyrite (yellow upper right)is corroded by galena (medium grey). The right photo shows pyrite which is corroded by silicate groundmass. Note: asp = arsenopyrite, chp =
chalcopyrite, ga = galena, py = pyrite, sil gm = silica groundmass

Sample No. 3A & 3B
MEGASCOPIC CHARACTERISTIC
Field Name: Potassic altered diorite
Nature of Sample: Rock chip
Minerals Visible: Megacryst of K-feldspar, biotite vein, chlorite, calcite and quartz vein,
pyrite, chalcopyrite
Texture: Biotite vein cross cut diorite
Colour: Pale grayish-pinkish with black fleck of mafic mineral
Grain Size: Fine to medium grained
Other Comments: The sample exhibits vein texture resulting from the interlayering of
very fine grained biotite cross cut feldspatic groundmass.
MICROSCOPIC CHARACTERISTICS OF ALTERED ROCKS
Constituents: (Percent visual estimate)
90% K-feldspar, quartz and scarcely calcite product of K-metasomatic
alteration, occur as fine-medium grained aggregates, hornfelsic and
interlocking texture that are seen to replace the intermediate
plagioclase and fill irregular microfractures. It is a late metasomatic
alteration event, and over prints, and hence masks the earlier sericitic
and argillic alteration even.
7% Biotite, products of potassic alteration, occur in about equal
abundance as fine crystalline aggregates that are seen to cross cut the
primary intermediate plagioclase, and associated alkali feldspar,
hornblende to varying degrees, ranging from moderate to almost
complete. Late phyllic overprinting by sericite and microfracture
filling by sericite can be seen.
3% Opaques occur as scattered, discrete, interstitial and intergranular
anhedral to euhedral grains, blebs and clusters that appear to be mainly
composed of accessory magnetite.
Texture: Relic of phaneric porphyritic and hornfelsic groundmass Metasomatic
Alteration: Potassic with secondary K-feldspar and biotite
Petrogenesis: A strongly microfractured, strongly silicified, propylitized and argillic
altered, fine grained biotite- hornblende-quartz diorite.
Remarks: The residual andesine and abundant hornfelsic and interlocking texture
secondary biotite, K-feldspar and quartz present suggest that the
protolith was a medium grained hornblende diorite.
ROCK NAME: Strongly microfractured and potassic altered of hornblende diorite or
Microdiorite
41
Potassic alteration is shown by abundant of feldspar and quartz that cross cut by secondary
biotite with the expulsion of fine‐grained disseminated magnetite. Plagioclase feldspar is
partly altered to sericite whereas biotite chloritized and silica enrichment giving hornfelsic and
interlocking texture Note: b‐1i = primary biotite, bi‐2 = secondary biotite, ch = chlorite, ep =

Sample No. MLW-05A, 05B, & 05C
Location: Mallawa
Rock name: Garnet Skarn with iron carbonate alteration and base metal sulphide
mineralization
Field Description: Garnet Skarn
Offcut Description: A porous, pale green to tan brown rock consisting of carbonate
(dolomite/siderite) which pseudomorph garnet and chalcopyrite/pyrite
Thin Section Descriptions (Constituent in %)
Garnet 5%, Pyrite 3%, Chalcopyrite 2%, Sphalerite 0.5%, Galena 0.5%, Calcite 75%, Sericite
9% and Quartz (5%)
Description: An intensely altered (carbonatized) skarn. Garnet was the originally
the primary constituent of this rock, in loosely interlocking medium-
coarse sized euhedral-subhedral grains. Abudant sulphides and minor
anhedral quartz have been deposited interstitially to the garnet. The
garnet is mostly altered and replaced by very fine-grained iron bearing
carbonate (siderite).
Pyrite is the most abundant sulphide, forming irregular-shaped,
coarse-grain aggregates disseminated through the skarn. These are
overgrown and rimmed by a small amount of chalcopyrite.
Trace amounts of galena infill small cavities in both sphalerite and
chalcopyrite, and sometimes appear to overgrown (and hence postdate)
both sphalerite and intergrown rhombic iron carbonate.
Comments: Garnet skarn with alteration and sulphide deposition as follows
43
Skarn altered diorite consist of mainly medium‐coarse grained calcite, biotite, chlorite,
epidote, sericite and garnet. Feldspar and mafic minerals are partly altered to carbonate, biotite, chlorite, epidote secondary quartz, sometime associated with opaque minerals which mostly consist of base metal sulfide. Note:bi = biotite, ca = calcite, ch = chlorite, ep = epidote, ga =
garnet, Kf = K‐feldspar, mu = muscovite, om = opaque mineral, pl = plagioclase, py = pyrite,
qz = quartz, sc = sericite
44
Pyrite shows bright reflectance and porous crystals disseminated in silica groundmass of
altered materials. Chalcopyrite (yellow) shows faint reflectance differences due to compositional variations and partly altered tobornite. The lowest photos shows pyrite which area corroded by silicate groundmass. Note: bo = bornite, chp = chalcopyrite, py = pyrite, sil
gm = silica groundmass

Minerals Visible: Quartz, feldspar, muscovite, sericite minor calcite, and chalcopyrite
and pyrite.
Texture: Possibly relic phaneritic and microporphyritic.
Colour: Pale grey.
Grain Size: Fine grained.
Other Comments: This weakly mineralized (chalcopyrite and pyrite) rock appears under
a binocular microscope to be strongly or pervasively metasomatically
altered, fractured and cross cut by biotite vein, possibly
microporphyritic, intermediate igneous intrusive with diuretic norm.
Primary silicate minerals appear to be rare as residual grains.
MICROSCOPIC CHARACTERISTICS
Constituents: (Percent visual estimate)
65% Quartz, sericite, muscovite, representing products of silicic, CO2
metasomatic and K-metasomatic alteration processes, occur in about
equal abundance as fine interlocking aggregates that in places exhibit
the relic microporphyritic fabric of a diorite, possibly a diorite
microporphyry, as suggested by the rare residual andesine present and
chloritized prismatic hornblende. Hornblende is mostly altered to
chlorite, muscovite and sericite. Primary quartz is absent. Quartz and
calcite also filled irregular microfractures. Sericite pseudomorphs after
tabular and lath shaped andesine microphenocrysts are also
represented. Epidote present scarcely, partly associated with biotite
vein.
25% Chlorite of metasomatic origin occurs as tabular and prismatic
pseudomorphs after primary hornblende grains and clusters and rare
microphenocrysts. Residual biotite present as microveinlets cross cut
the sericitized K-Feldspar.
10% Opaques occur as scattered, discrete, subhedral and euhedral

Muscovite, silicic, CO2 metasomatic, sericitic and chloritic.
Petrogenesis: A strongly microfractured and pyritized, sillicified, sericitized,
carbonatized and chloritized, diorite microporphyry.
Remarks: The relic igneous, plus the presence of residual andesine and
chloritized hornblende, suggest that the protolith was a diorite
microporhyry. Metasomatic alteration was almost pervasive and
selective. The oxide and sulphide opaque phase present can only be
positively identified in reflected light.

34 Appendix 2: Internal TFR Report on Exploration Activities
Malawa Porphyry Copper –Gold and Related Deposit Exploration Target
1. Extensive granodioritic-dioritic rocks throughout Malawa until Pangkajene with strongly indication of potassic and propylitic zone alteration that outcropped in the creek near Malawa village.
2. Significant skarn vein type which enveloped by propylitic alteration zone that outcropped on the middle downstream of Malawa creek (MLW-5). The vein is dominated by carbonate mineral consist of coarse to very coarse grained chalcopyrite, pyrite, arsenopyrite and scarcely galena and sphalerite.
3. Discovery of vein that probably as a part of a stockwork system which enclosed by advanced argillic or phyllic (quartz+sericite+pyrite) alteration zone on MLW-2. The geochemistry analysis on the vein sample of MLW-2 shows interesting gold grade of 1.2 ppm Au and 5.2% of Cu.
4. By this first field visiting program is found also in the Malawa area (in observation point of MLW-5) some thin film of malachite.
5. The Malawa area is associated with favorable structural and its tectonic setting of Island Arc environment that bounded by major strike slip faults and shear. The best extension for porphyry copper prospect is to the west and northwest in radius 30-40 km from Malawa until Pangkajene area.
Zones
6. Malawa district lies presumably in the favorable metallogenic belt associated with the ancient calc alkaline volcanic and intrusive rocks of South Celebes. The famous Porphyry Copper and Gold mining recently present in Tombolilato and Messel of Gorontalo Provice in the northern arm of Celebes.
7. Malawa is located on Kabupaten Bone (Bone District) which has easy access to major highway, electricity power and logistic.
8. There are no environmental issues to prevent mining.
9. According to the exploration steps on the Malawa property, there has no drilling data (never have been drilled).
PROPERTY DESCRIPTION
The Malawa Prospect currently is a 800 Ha mining permit located approximately three hours
northeast of Makasar, in Sulawesi, Indonesia The permit is approximately 20 km north of the
Bone Highway which is a major highway connecting Makassar to Bone and other
communities.

REGIONAL GEOLOGY
Figure 1. Simplified regional geological map of Malawa-Pangkajene area. This map is cropped out from “Geologic Map of the Pangkajene and Western Part of Watampone Quadrangle of
Sukamto (1982).
The Malawa Prospect is situated in the South Celebes Arm (Active Island Arc System) and
along the southwestern axis of the Walanae Fault Zone (Fig. 1). It is underlain by the mélange,
metamorphic and ultramafic complexes of Triassic-Cretaceous ages. These Mesozoic
complexes area intruded and covered by Tertiary volcanic and sedimentary rocks.
Malawa has a very favorable tectonic and structural position for the emplacement of porphyry
type deposits, especially in the western part until Pangkajene. It is bounded by major strike
slip faults Walanae Fault Zone (WFZ). This type of tectonic activity can create pull-apart
basins which are zones that provide high-permeability conduits for the emplacement of
mineralized magmas to shallow crustal levels.
LOCAL GEOLOGY
The Malawa Formation is composed of non-marine of fluviatile sedimentary rock of
conglomerate, sandstone, claystone and coal (Tem). There are also interbedded marine
sediments of limestone of Tonasa Formation (Temt). Numerous intrusives are evident ranging
from basalt (b) granodiorite (gd), syenite (s) and diorite (d) that are placed as coeval with the
Early to Late Miocene volcanics. There also may be younger volcanic and intrusive rocks on
Malawa but only precise age dating would determine this. The alteration zone is coincident
with a circular structure in the northern part Bukit Maraja (bukit=hill) that is bounded on the
south by a reverse fault which appears to have been formed by an intrusive event along the
WFZ. The alteration zone of Malawa is presumably cut by an extensive network of altered and
sheared dikes and also by late stage breccias.
50
Alteration and Mineralization
The alteration as seen from the highway is striking. Fresh to Propylitically altered volcanic
and intrusive rocks are in sharp contact with a lower Potassic Alteration Zone (PAZ)
characterized by light pinkish to milky white K-feldspar altered rock, segregation or biotite
vein; red hematite clay altered rock and patchy zones of white gypsum. Below the PAZ zone
is a central core of bright white colored rock exposed in the bottom of a ravine which is
composed of quartz, sericite, pyrite and kaolinite. This zone is presumably related to the
Phyllic alteration zone characteristic of porphyry style alteration. In some samples is identified,
K-feldspar veining is evident which could be a remnant of an earlier Potassic zone telescoped
by destructive later alteration events. Within the alteration (leached zone) mineralization is
predictably low due to acid destruction. However anomalous copper values of 0.01-7.31% Cu
have been recorded associated with the copper minerals chalcopyrite, covelite and malachite.
Numerous occurrences of copper gossans were found within the alteration zone associated
with sheared and intensely altered rocks. Anomalous gold values of up to 1.2 ppm have been
found by our chemical analyses on MLW-2. On the periphery of the alteration zone to the east
other investigators have found malachite and extensive chalcopyrite veins assaying up to 7.3%
Cu. Float in streams drainages contain mainly chalcopyrite. Principle alteration suites
associated with preliminary studies of this porphyry copper prospect: Cu, Au, Ag, Pb, Zn
Table 1: The geochemical analyses of preliminary field study of Malawa prospect as shown bellow
RECOMMENDATION
1. Detail ground survey of geological and geophysical mapping for 800 Ha Malawa property.
2. The exploration property has to be extend (from only 800 Ha surrounding Malawa’s village) to the west and northwest of with radius 30-40km starting from Malawa until Pangkajene.
3. Conduct an Resistivity (R) and Induced Polarization (IP) and ground magnetic survey over the alteration zone to determine drill targets.
4. Drill minimum two deep with approximately 1000 m total length using reverse circulation (RC) holes followed up by another two core holes.

37 Appendix 5: Recommended Sampling Procedures Since the project is in its early stages, the only sampling that has been undertaken, as far as
can be determined, is the collection of rock grab samples. In order to ensure compliance to
NI43-101 during the exploration program, the following sampling procedures have been
suggested:
37.1 Geochemical (Pit) Samples
Depending on the density of sampling required, the Project Geologist will select pits to be
sampled after consulting with the Company Exploration Manager and the QP. Pits are to be
dug down to bedrock where possible or to a depth of 0.5m. Individual pits must be marked
with a plastic sample tag tied to a stake, clearly indicating the sample number using a
permanent marker pen.
The profiling should be undertaken using the following procedure:
Obtain the 3D coordinates of the surface collar using the GPS. In order to increase the
accuracy of the measurement, the GPS should be set to “enabling GPS” so that the
values can be averaged.
Record the date, total depth of the pit, the rock type and any alteration.
The dip and strike of any structural features such as joints, veins and faults should
also be noted.
Using a small spade or geo-pick, cut a V-shaped channel in the formation while
collecting the material into a sample bag.
Samples of approximately 2kg are to be collected.
Samples must be double-bagged in strong plastic bags. One sample tag tied to the
inside bag and one to the outside. Plastic bag ties and plastic tags marked with a
permanent marker are recommended.
37.2 Trench Samples
Trench samples allow for observations to be made of the change in grade or quality on the
same lithology or of the change in lithology over the length of the trench. The following
methodology is recommended: Obtain the 3D surface collar coordinates at each end using a GPS. In order to increase
the accuracy of the measurement, the GPS should be set to “enabling GPS” so that the
values can be averaged;
Clean one long face with a spade from top to bottom if the side of the trench or rock
outcrop is to be sampled. Alternatively clean the bottom of the trench so that it is free
from any material that has fallen from the surface;
Record the date and measure the total length and depth of the trench;
Log the trench in as much detail as possible, taking note of any alteration, lithology
and structural features as per the prescribed log sheet;
Using spray paint, measure and mark intervals of 1m from across the base of the
trench;
Photograph the face/trench;
Number the samples from any end, ensuring this is consistent with other trenches;
Using a diamond saw in hard rock, or a small spade or geo-pick in weathered material,
cut a V-shaped channel while collecting the material into a sample bag;
Samples of approximately 2 kg should be collected.
75
Sampling lengths should be adjusted at the discretion of the geologist based on
changes in alteration or lithology;
Such changes must be recorded by the geologist on the sample bag and on the log
sheet.
In order to ensure compliance to NI43-101 during the exploration program, the following
sampling procedures has been suggested.
37.3 Geochemical (Pit) Samples
Depending on the density of sampling required, the Project Geologist will select pits to be
sampled after consulting with the Company Exploration Manager and the QP. Pits are to be
dug down to bedrock where possible or to a depth of 0.5m. Individual pits must be marked

and structural features as per the prescribed log sheet;
Using spray paint, measure and mark intervals of 1m from across the base of the
trench;
Photograph the face/trench;
Number the samples from any end, ensuring this is consistent with other trenches;
Using a diamond saw in hard rock, or a small spade or geo-pick in weathered material,
cut a V-shaped channel while collecting the material into a sample bag;
Samples of approximately 2 kg should be collected.
76
Sampling lengths should be adjusted at the discretion of the geologist based on
changes in alteration or lithology;
Such changes must be recorded by the geologist on the sample bag and on the log
sheet.
37.5 Diamond drilling
10.1.1 Drill Core Samples
Drill cores must be packed into metal core boxes. Either the responsible geologist or
geological assistant will undertake the following tasks: Witness and verify the measuring of the depth of the hole;
Observe the correct packing of the core;
Observe the correct numbering of depth blocks, taking note of core losses or gains;
Ensure that the core is transported to the core yard with the minimum of disturbance;
The length of the core samples should be based on the geology encountered down the
hole. The minimum sample interval should be 20cm and the maximum sample
interval should not exceed 1.5m;
All core is to be photographed and the output is to be forwarded to the core shed on a
regular basis;
One half of the core over the target mineralisation is to be sampled and the remaining
half is to be stored for future reference;
Should a request for a duplicate sample be received, the stored half of the core should
be quartered and the remaining quarter should again be stored;
Sampling should start 50cm above the mineralised area and end 50cm below;
Record the data onto the computer database on a daily basis;
A permanent core yard geologist is to be responsible for the sawing, sampling and
storing of the core. The responsibility of the field geologist is the marking and
logging of the core.
For diamond drill holes, the following data must be captured: The length of the core run, in metres and millimetres, as defined by the driller’s core
blocks;
The length drilled, measured length of core recovered (in metres and centimetres) and
a calculation of the per cent core recovered;
A graphic lithological section;
Lithological features such as the degree of weathering, colour, grain size, field rock
name (often in capitals or underlined);
Proportions of rock minerals;
The attitude of bedding or foliation (the angle between the planar structure and the
long axis is generally stated, often termed );
Attitude and spacing of other structures such as joints and sheared zones. It is also
important to make note of the width of the sheared zones;
The interval in which ore minerals are present is to be listed separately, with ore
mineral species in capitals or underlined. Notes should also be colleted on the
orientation of ore minerals, the gangue minerals present, grain size and a visual
estimate of the percentage of metal.
Diamond core should be logged using the coding system provided by Micromine. It is good
practice to use summary logs for modelling purposes and to keep the detailed logs for
77
reference if required. Diamond core should be geotechnically logged, photographed and the
recovery should be determined while the core is still wet and sitting in the tube. If this is not
possible, all man-made breaks should be clearly marked with an X when the core is being
placed in the core tray.
Core boxes should be transported to the base on a daily basis and stored under cover. All
cores should be logged within two days of completion of the hole. Due to high humidity and
rainfall, core left exposed will be weathered very quickly. All observations are to be
transferred to the database at least on a weekly basis. The order of the logging procedure is
described below: Lay the complete core out in the core boxes;
Join and align the core prior to marking off a centre line for cutting with a diamond
saw (which will occur later). Joining and aligning the core will also ensure that all
length measurements are accurate;
Identify and record the major lithological changes;
Record the major structural features such as faults, veins and joints;
Log in the sequence prescribed in the log sheet, ensuring that all the sections in the
sheet are addressed.
37.6 RC Drilling
The logging of RC drill cuttings is more difficult and the information acquired is less detailed
relative to diamond core. The following information should be captured during the logging of
RC chips: The weight of each sample should be measured in order to determine recoveries.
Coupled with the theoretical mass that should be recovered according to the diameter
of the hole, the sample weight can be used to calculate the per cent recovery;
The depth of the water table should be noted to assist with subsequent hydrological
studies;
RC rod changes should also be noted in the logs, as well as the depths at which the
hole was stopped for any reason;
The penetration rate should be noted to provide a relative measure of rock hardness.
RC drill samples will be collected by the drill crew at 1m intervals into a 20kg numbered bag
and delivered to the sample preparation area at the camp. Field geologists should regularly
observe the sampling to ensure that samples are taken according to the specifications in the
drill contract.
RC drilling should be carried out by experienced drillers using the appropriate equipment.
This equipment would include compressors with sufficient air capacity for the depths and
material drilled. Air capacity can be easily boosted by using auxiliary compressors that are
capable of providing sufficient air to prevent water inflow below the water table. A down-
hole face sampling hammer should be used as well as stabilisers to prevent deflection of the
hole near the collar. In addition, the hole should be sealed to prevent air and dust loss at the
collar. It is good practice to implement the use of 'blow-backs' at the end of each sample run
whereby the bit is pulled back from the bottom of the hole and the hole is cleaned out for a
few seconds with air.
RC sampling should always be carried out with care so that the results can be successfully
matched with any diamond twin holes. This assists in allaying any concerns regarding RC
drilling as a resource definition tool. There is much debate regarding the sampling of wet RC
holes. If the sample cannot be kept dry by the air pressure used, then the samples should not
be collected at all.
78
RC samples should be collected through a properly designed and fitted cyclone that minimises
dust loss. After collection and weighing of the entire sample, a riffle splitter should be used to
split the sample down to a manageable size for assaying; approximately 4kg. Spear sampling
is acceptable if it is carried out properly and with due care in terms of sample homogenisation.
Sample residues should be clearly marked and stored securely under cover. shows the
proposed RC sampling procedure. The samples are to be numbered in sequence from the top
to the total depth with the numbering correlating to the drill depth.
Figure 37-1: RC sampling procedure.
37.7 Drill hole and Sample Numbering
It is recommended that a consistent numbering system be developed that adequately identifies
the project, sampling method (surface grab, trench, drill core or RC) followed by a number in
