Point Location Description: Trenches and diamond-drill holes.

Location Method: Conversion from MDI

Access Description: This occurrence is located about 31 km southwest of Pickle Lake and 425 m southwest of the creek mouth at the west end of Bancroft lake (aka Ben Lake) on the north side of the creek. Access to this occurrence is by appropriately equipped aircraft to Bancroft Lake and then a traverse to the occurrence area. Bancroft Lake is very shallow with a soft bottom and is not recommended for landing a large aircraft.

Exploration History

1959: Hasaga Gold Mines Ltd. optioned a claim block covering this occurrence from B. Ohman and K. Koval. Hasaga performed prospecting, geological mapping, trenching and diamond-drilling on the optioned claim block. 1963: Pickle Crow Gold Mines Ltd. sampled 5 trenches on this occurrence and reported significant gold values. 1982: 493217 Ontario Ltd. did ground mag and EM surveys which covered this occurrence. 1983-84: Moss Resources Ltd. conducted geological mapping, mag, EM, IP, rock and soil geochemistry surveys which covered this occurrence. This included trenching and sampling and was followed up by a 20 hole, 1522.78 m, diamond-drill program. 1986: Power Explorations Inc. completed a 16 hole, 1430.43 m, diamond-drilling program on a claim block including 2 DDH totalling 203.25 m on this occurrence.

Lithology

Lithology Comments

May 29, 2020 (B Nelson) - Zone 1 outcrops intermittently over an east-trending strike length of about 1 km. The gold mineralization occurs in a metasedimentary unit near the contact with a mixed intermediate to mafic metavolcanic succession. Within the metasedimentary unit, the gold mineralization occurs with quartz stringers, tourmaline and pyrite in a variety of rock types including argyllite, a deeply weathered limonitic schist and iron formation. The area is intruded by quartz-feldspar porphyry dykes and sills. Visible gold has been panned from the limonitic schist. In drill hole BL-84-19, the gold mineralization is associated with sulphide-bearing mafic tuff beds in the metasedimentary unit.

Mineralization

Mineralization Comments

May 29, 2020 (B Nelson) - When Zone 1 was sampled by Pickle Crow Gold Mines Ltd. in 1963, assay results of 2.86 oz/ton Au over 28 cm, 4.07 oz/ton Au over 40 cm, and 0.49 oz/ton Au over 81 cm were reported from 3 separate trenches. Repeated Moss Resources sampling of the 4.07 oz/ton Au sample interval yielded values of 0.295, 0.40 and 0.28 oz Au. Moss Resources' best assay result of 1.054 oz/ton Au over 30 cm came from another trench. Diamond-drill hole BL-84-19 intersected values of 0.06 oz/ton Au over 30 cm and 0.03 oz/ton Au over 55 cm within the zone of the occurrence.

May 29, 2020 (Therese Pettigrew) - Gold mineralization occurs in and near a 5,400 foot long band of argillaceous and siliceous sediments and minor iron formation which outcrops sporadically between lines 2+00E and 36+0CE from 2*00S to 3+00S. In DDH BL-84-19, two significant Intercepts were made at shallower depths. The first at 5 feet below surface yielded 0.04 oz/ton over 3.0 feet (1.37 g/t Au over 0.91 m) in gabbro with 0.5% pyrite in fractures. The second at vertical depth of 31 feet yielded 0.04 oz/ton over 2.0 feet (1.37 g/t Au over 0.61 m) in intermediate to mafic tuff with 5% quartz veins and 1% pyrrhotite at contacts. Trace chalcopyrite was noted in the tuff (Assessment report 52O07SE0012).
