Marifil Mines Toruel Project Fact Sheet
2
OVERVIEW Toruel is a silver-copper project with important accessory values of gold and indium. Polymetallic sulfide mineralization is hosted by epithermal breccias and veins that cut a thick pile of Jurassic age acidic volcanics. The property consists of 5,736 hectares located in the Rio Negro Province near the small mining and railroad town of Los Menucos. Twenty epither- mal veins are known to occur within a complex fault bounded structural block some 4.5 kilometers wide and 7.7 kilometers long. Marifil has done three episodes of drilling scattered about this structural block, with the majority of the holes focused on the Toruel vein. Combined reverse circulation and diamond core drilling total 61 holes for 5,890 meters. All this drilling is relatively shallow, with the deepest penetration being 125 meters vertical depth on the Toruel vein. There are sufficient close spaced drill penetrations on the Toruel vein to calculate a small, near surface high-grade resource. The most prominent mineralization so far found on the property is the Toruel vein. This system comprises a strongly silicified fissure vein and breccia with numerous smaller veins splitting off or horse tailing away from the main vein to form smaller, sub-parallel or sygmoidal veins. The main vein system can be divided into three blocks: an eastern block, a central block and a western block. The eastern block forms a low ridge up to 20 m high, 100 m wide, and more than 1,200 m long. The main part of the vein runs the crest of the hill and averages more than 5 m wide. Tens of surface channel samples show silver values averaging in excess of 400 g/t with one sample containing 5,871 g/t silver. Gold anom- alies are variable ranging from 0.14 g/t up to 7g/t but in general the average is closer to 0.50 g/t Au. The down-faulted central bock is several hundred meters long but largely covered by a thin veneer of alluvium. Mineralization comprises silver-indium bearing tetrahedrite, chalcopyrite, bornite and minor amounts of pyrite. DDH 32 intercepted 6.70 meters of 2,045 g/t silver with 5.34 % copper which includes 5.40 meters of 309 g/t indium. The fault up-thrown western block is also several hundred meters long but silicification there is greatest - up to 90 m wide. Surface rock geochemical values are strongly anomalous in precious metals and epithermal indicator elements such as mer- cury, arsenic, antimony, barium and tellurium. Geologists interpret this western block to be a silca cap at the very top of a com- pletely preserved epithermal system, and speculate deep drilling may reveal bonanza grades in an underlying boiling zone.

Transcript of Marifil Mines Toruel Project Fact Sheet
OVERVIEWToruel is a silver-copper project with important accessory values of gold
and indium. Polymetallic sulfide mineralization is hosted by epithermal
breccias and veins that cut a thick pile of Jurassic age acidic volcanics.
The property consists of 5,736 hectares located in the Rio Negro Province
near the small mining and railroad town of Los Menucos. Twenty epither-
mal veins are known to occur within a complex fault bounded structural
block some 4.5 kilometers wide and 7.7 kilometers long.
Marifil has done three episodes of drilling scattered about this structural
block, with the majority of the holes focused on the Toruel vein. Combined
reverse circulation and diamond core drilling total 61 holes for 5,890
meters. All this drilling is relatively shallow, with the deepest penetration
being 125 meters vertical depth on the Toruel vein. There are sufficient
close spaced drill penetrations on the Toruel vein to calculate a small, near
surface high-grade resource.
The most prominent mineralization so far found on the property is the
Toruel vein. This system comprises a strongly silicified fissure vein and
breccia with numerous smaller veins splitting off or horse tailing away from
the main vein to form smaller, sub-parallel or sygmoidal veins. The main
vein system can be divided into three blocks: an eastern block, a central
block and a western block.
The eastern block forms a low ridge up to 20 m high, 100 m wide, and
more than 1,200 m long. The main part of the vein runs the crest of the hill and averages more than 5 m wide. Tens of surface
channel samples show silver values averaging in excess of 400 g/t with one sample containing 5,871 g/t silver. Gold anom-
alies are variable ranging from 0.14 g/t up to 7g/t but in general the average is closer to 0.50 g/t Au.
The down-faulted central bock is several hundred meters long but largely covered by a thin veneer of alluvium. Mineralization
comprises silver-indium bearing tetrahedrite, chalcopyrite, bornite and minor amounts of pyrite. DDH 32 intercepted 6.70
meters of 2,045 g/t silver with 5.34 % copper which includes 5.40 meters of 309 g/t indium.
The fault up-thrown western block is also several hundred meters long but silicification there is greatest - up to 90 m wide.
Surface rock geochemical values are strongly anomalous in precious metals and epithermal indicator elements such as mer-
cury, arsenic, antimony, barium and tellurium. Geologists interpret this western block to be a silca cap at the very top of a com-
pletely preserved epithermal system, and speculate deep drilling may reveal bonanza grades in an underlying boiling zone.
The Canyon vein is a prominent sub-parallel vein about two kilometers to the southeast of the Toruel vein. Geologic mapping
show it to be up to ten meters wide and at least 1.7 kilometers long, and con-
sisting of banded, or variegated, chalcedonic quartz and locally hydrothermal
breccias. The Canyon vein has not yet been trenched or drilled. Surface rock
chip samples contain geochemically anomalous epithermal minerals and ele-
ments with up to 2.79 g/t gold, 125 g/t silver, 10,000 ppm lead, 151 ppm arsenic,
and 10 ppm antimony. The outcrops of the vein exhibit high level epithermal tex-
tures including replacement of barite and calcite by quartz, indicating very good
prospectively for drill discovery of ore grade precious metals below.
