1. INTRODUCTION
Exploration Permit for Minerals (EPM10869) is located about 50 kms East of Charters Towers and 15 kms SW of Ravenswood, in North Queensland (Drawing No. 70013).
The permit is one of a group of 14 tenements in the Ravenswood district over which exploration was managed and conducted by MIM Exploration Pty Ltd (MIMEX) for the MIM Holdings Ltd group of companies until December 2001, when MIMEX transferred management of the Ravenswood EPM’s to Carpentaria Gold Pty Ltd. Carpentaria Gold Pty Ltd which operates and manages the Ravenswood Goldmines.
The project area is being explored for sub-volcanic breccia deposits (Mount Wright and Mount Leyshon types) and mesothermal style gold mineralisation (Ravenswood, Sarsfield type). Mineralisation is known to occur at a number of locations within the tenements, within and adjacent to alteration zones and regional structural features.
Under the previous management of MIMEX, a range of exploration works have been carried out over a period of over 20 years. This area of exploration lies mainly within a radius of 30kms from the Ravenswood Goldmine. This wider area has been scrutinised mainly by using stream sediment BCL gold geochemistry together with aeromagnetic survey data to search for possible signatures of significant gold mineralisation. Within a 5km radius of Ravenswood and Mt Wright 200m x 200m BCL soil geochemistry has been used together with ground magnetics and electrical geophysics (MIMDAS & CSAMT). Intensive RC and diamond drilling programs have been carried out in and around Ravenswood and Mt Wright with minor drilling on a number of prospects in the surrounding areas.
Carpentaria Gold operating on a tight exploration budget and with limited manpower and logistical resources has been relatively restricted to drilling of advanced prospects, with a view to providing mill-feed and upgrading existing resources.
Exploration over the 9 sub-blocks relinquished from this EPM has been limited to interpretation of pre-existing datasets.
After a review of all geochemical, geological and other data, the 9 relinquished sub- blocks are considered to have minimal potential to host economic mineralisation of interest to Carpentaria Gold Pty Ltd.
2. LOCATION AND ACCESS
EPM 10869 is located 50kms East of Charters Towers and 15 kms SW of Ravenswood. Access to the EPM is via the Flinders Highway from Townsville to Mingela then via Burdekin Falls Dam road. Station tracks provide general access throughout the area of the EPM.

3. TENURE
EPM 10869 comprising 67 sub-blocks was granted to Carpentaria Gold Pty Ltd for a term of 5 years commencing on 31 January 1996. The area of the tenement was reduced by 33 sub- blocks in January 1997, and 16 sub-blocks in January 1999.
The area of the tenement was further reduced by 9 sub-blocks in January 2003, leaving 9 sub-blocks.

4. PREVIOUS EXPLORATION
A number of companies have previously explored the area for both precious and base metal mineralisation.
Cormepar Minerals Pty Ltd A to P 1169 & 1170 Poseidon Exploration Limited EPM 7453, 7737 & 7881
A to P 1169 and 1170 - Cormepar Minerals Pty Ltd
Layton and Associates Pty Ltd carried out geological and geochemical exploration programmes on behalf of Cormepar Minerals Pty Ltd during 1973 and 1974.
Programmes included regional drainage geochemical sampling, regional mapping and follow up soil and drainage sampling in anomalous areas located during the regional surveys.
It was concluded that the targeted Mt Windsor Volcanics within the tenement had little potential for economic volcanogenic massive sulphide style mineralisation.
EPM 7737 - Poseidon Exploration Limited
( Partial Relinquishment Report for period ending 31 st January 2003 )
( June 2003 ) ( EPM 10869 “Kirkton” )
The tenement covered the Boori intrusive complex with porphyry style gold mineralisation, the primary target.
As for other tenements in the Mount Canton Project area, work undertaken included interpretation of regional geophysical data sets, satellite imagery and a review of previous exploration activities.
Follow up programs included regional BLEG drainage sampling, a total of 25 samples and rock chip sampling, a total of 17 samples during reconnaissance. No significant gold mineralisation was detected from any of the work and it was recommended that the tenement be surrendered in full.
EPM 7881 - Poseidon Exploration Limited
The tenement was previously part of EPM 5948 held Porphyry (1939) Gold Mine NL, a wholly owned subsidiary of Normandy Poseidon Limited. The area was reapplied for following favourable results from work conducted on surrounding tenements.
The main target was buried porphyry gold mineralisation.
Work carried out included interpretation of regional airborne magnetic and radiometric data, satellite imagery, photogeological mapping at 1:25,000 scale and limited rock chip sampling during reconnaissance work.
It was concluded that no significant target areas warranting further evaluation existed and the tenure surrendered.
5. REGIONAL GEOLOGY
The area of EPM 13207 covers a portion of the Ravenswood Batholith, the major element of the Ravenswood - Lolworth Province, which is bounded to the north by the Broken River Province, with the Drummond and Bowen Basins to the south. To the east is the north-eastern part of the New England Fold Belt.
The batholith comprises Early Ordovician, Middle Silurian to Middle Devonian and Middle Carboniferous to Early Permian intrusive episodes of predominantly granite to granodioritic composition. Host units to the batholith are the late Cambrian to Early Ordovician volcanics and sediments of the Seventy Mile Range Group and Early Palaeozoic Charters Towers Metamorphics, Argentine Metamorphics and Kirk River Beds.
6. WORK COMPLETED BY MIM EXPLORATION PTY LTD
A total of 66 soil samples were taken on the relinquished part of EPM10869. These samples were collected on a 200m x 200m grid by a 4WD mounted utility with
motorised auger drill. Approximately 4kg (–4mm) B/C horizon soil was generally collected. This was analysed by Bulk Cyanide Leach at ALS Townsville Laboratory, for gold and silver. The sample locations are given in drawing No 70034, and as an excel file in the appendix.
A helicopter borne magnetic survey was flown over part of EPM 10869 during April 1999. The processed data covering the relinquished sub-blocks is shown in drawing No. 70033. Survey specifications are set out below.
