Geology Comments

Feb 27, 2015 (Therese Pettigrew) - The subject property is dominantly underlain by mafic to intermediate metavolcanic, metavolcaniclastic and metasedimentary rocks comprising the Favourable Lake-Setting Net greenstone belt. These stratified rocks are locally deformed and intruded by intermediate to felsic intrusives (Blanchflower, 2006).

Mineralization

Mineralization Comments

Nov 02, 2007 (Mark Puumala) - Johnson (1987) reported that the Borland Lake prospect consists of two parallel approximately east-striking, silicified, silver-bearing shear zones (north and south zones) hosted by metasedimentary rocks (greywacke). Blanchflower (2007) reports the presence of a mineralized shear oriented 280/80. The deposit was delineated by diamond drilling over a total strike length of 365 m, in an area located immediately to the east of an ultramafic intrusion (Johnson 1987). The two parallel shear zones have been named the north and south zones, with the north zone having an average thickness of 2.1 m and the south zone having an average thickness of 3.2 m. According to Johnson (1987), silver mineralization occurs in three distinct ¿cigar-shaped¿ lenses that plunge to the southeast at approximately 45 degrees. Each of these lenses is reported to cover a strike length of approximately 46 m and is open at depth. Mineralization is reported to consist of varying amounts (in order of abundance) of pyrrhotite, pyrite, argentite, galena, sphalerite and arsenopyrite (Johnson 1987). The total sulphide content of the mineralized zones typically does not exceed 10%, and the sulphides occur as irregular stringers and disseminations along foliation and shear planes. A distinct zone of garnet alteration is reported by Johnson (1987) to occur in the hanging wall sediments. The most notable structural feature in the vicinity of this prospect is the approximately 300-striking Bear Head fault zone, which is located immediately to the north (as shown on ODM Map 2262). Geological information compiled by Blanchflower (2007) also indicates that foliations in the area generally trend 300 with steep northerly dips, and that this fabric is axial planar to commonly-observed tight/isoclinal folds. North-trending and northeast-trending faults are also reported to occur in the area. Blanchflower (2007) reports that a non-NI 43-101 compliant reserve estimate of 431,967 tons grading 8.43 oz/ton Ag and 0.02 oz/ton Au was calculated for this deposit by Massive Energy in 1986. Significant gold and silver assay results from the historical diamond drilling programs carried out on this deposit are compiled by Blanchflower (2007). It should also be noted that this deposit also hosts significant lead and zinc mineralization. Surface chip samples (covering 1 m2) collected by Blanchflower (2007) assayed up to 2.67% Zn and 2.18% Pb.

Feb 27, 2015 (Therese Pettigrew) - The most significant intercepts of the 2010 drill program were in Hole 6 (75.2 grams Ag/tonne, 6.04% Zn, 0.55% Pb across a true width of 0.5 meters), Hole 7 (0.3 g/t Au, 118.8 g/t Ag, 1.4% Zn and 1.8% Pb across a true width of 2.6 meters), Hole 11 (two intercepts including 2.13 g/t Au, 14.5 g/t Ag, 0.46% Zn and 1.38% Pb across a true width of 1 meter and 1.7 g/t Au, 170.0 g/t Ag, 1.9% Zn and 1.19% Pb across a true width of 2.0 meters), and hole 13 (19.5 g/t Ag and traces of the other reported metals across a true width of 18.1 meters) (Guyana Frontier press release, Oct 27, 2010). DDH B-11-01 encountered silver, gold, lead and zinc mineralized veinlets, disseminated sulphides and breccias from 76.8 to 90.8 m within siliceous metagreywacke and quartzite rocks, and in two other mineralized intervals between 92.1 and 108.9 m downhole. Sulphides containing argentite were noted in the core, with accompanying sphalerite, pyrrhotite and pyrite. The estimated true width of the mineralized interval was 7.7 m (25.26 ft), which averaged 291 g/t (8.49 ounces per ton) silver, including 365 g/t (10.65 oz/ton) silver over 6.08 m (19.94 ft). Minor values of gold, lead and zinc were also encountered. Hole B-11-02 was collared approximately 84 m from Hole B-11-01 and intersected mineralized zones at downhole depths of 23.8 to 64.5 m, and from 67.7 to 73.7 m. Mineralization was again observed within siliceous metagreywacke and quartzite rocks with notably higher silver and gold values than were seen in B-11-01, averaging 99 g/t (2.89 oz/ton) silver and 1.03 g/t gold over an estimated true width of 30.53 m (100.14 ft), which included 285 g/t (8.3 oz/ton) silver and 1.63 g/t (0.05 oz/ton) gold over 8.53 m (27.98 ft), and 438 g/t (12.78 oz/ton) silver and 2.99 g/t gold (0.09 oz/ton) over 4.6 m (15.1 ft). Pegmatites were observed cutting through the mineralized zones, from 64.5 to 66.24 m, for example (Guyana Frontier press release, June 12, 2011).
