- The showing, or the mineralization first encountered by drill hole NER-49, is located 300 m (984.3 ft) north of the northwest corner of Barnet Lake at NER 1 grid coordinates 57+00N and 1+00W. The showing is located 0.56 km (0.35 mile) north of SMDI 0127.
The showing area, as mapped by Reilly in 1991, is underlain by Unit Pie or the medium- to coarse-grained, sheared, quartz eye granodiorite to granite and Unit Ppm or the fine- to medium-grained, weakly- to moderately-foliated diorite to gabbro phases of the 5 km (3.1 mile) wide by 30 km (18.6 mile) long, complex, multi-phase Reynard Lake Pluton. Immediately west of the showing the Reynard Pluton rocks contact with north northeast-trending Units Rft and Rmx of the Ruth Lake Assemblage supracrustals. Unit Rft consists of a felsic monolithic tuff breccia with minor crystal tuff and silicified mafic crystal tuff. Unit Rmx consists of a mafic tuff or plagioclase crystal tuff and ash tuff.
A 100 m (328.1 ft) wide prominent aureole of contact strain surrounds the Reynard Lake Pluton in which the early D1 foliation is warped by F2, open to closed, megascopic, steeply-plunging folds. In this zone, one finds a well-defined stretching lineation, typically expressed as a L-tectonite, and an intersection lineation which was created by the meeting of the F2 fold axial planes and the S1 foliation. This north- to north-northeast-trending sequence of rocks dips 67° to 80°NW and plunges 54° to 67°NW.
Drill hole NER-49 encountered trace to 1% pyrite, magnetite, and pyrrhotite and trace to near-solid sulphide mineralization which includes chalcopyrite (occurring as small clots and disseminations) within a sequence of fine-grained, dark grey, massive, silicified and somewhat granitized dacite with minor semi-conformable feldspar porphyry and granitic sills (176.8-182.0, 206.5-208.0, 226.3-227.2, 227.7-228.7, 238.3-240.8, 238.3-240.8, 248.8-251.2, 252.2-252.9, 257.1-end of hole).

- 12/6/1994 In 1961, Cominco diamond drilled two holes on Barney Lake.
In 1969, Hudson Bay completed a ground turam survey over the showing area. Between 1969 and 1972, further drilling of electromagnetic conductors on the NER 1 grid in the Stitt Lake area was reported by Hudson Bay Exploration and Development Company Ltd. This program encountered the mineralization described by SMDI 0127.
On 1 August 1983, Hudson Bay Exploration and Development staked the showing area as S-102069. In this year, JMB Exploration completed a ground EM survey on adjoining ML 5268 (AF 63L09-0270). 1984, Hudson Bay completed a Maxmin II and magnetic survey over the NER 1 grid (AF 63L09-0298).
In 1987, L. Clarke completed a spruce bark biogeochemical survey on ML 5268 (AF 63L09-0336). In 1988, ground IP, resistivity, and IP surveys were completed on ML 5268 (AF 63-0002). In 1989, geological mapping, prospecting, rock sampling, and a ground magnetic survey was completed on ML 5268 near the showing (AF 63-0005).
In 1990, Hudson Bay completed further ground EM surveys on the NER 1 grid. In 1991, a ground VLF-EM survey (AF 63-0006) was completed over the NER 1 and 1X grids and drill hole NER-49 was completed just north of the northwest tip of Barney Lake at grid coordinates 3+00S and 5+30E (AF 63L09-0386). The mineralization intersected by this drill hole constitutes this showing.
In 1992, Hudson Bay completed drill hole NER-58 300 feet south of the showing on the northwest tip of Barney Lake to check for an extension of the mineralization encountered in drill hole NER-49 (AF 63L08-0006). The drill hole encountered one narrow intersection with visible gold which is reported above. The gold-bearing intersection occurs within an sequence of andesite to dacite flows which have been intruded by feldspar porphyritic granodiorite (135.7-139.4 ft) and quartz phyric granodiorite ((247.5 ft to end of hole).
Between 1994 and 1995, Hudson Bay completed drill holes FORM-1 to FORM-3 to test the mineralization encountered in holes NER-49 and NER-58 at depth (AF 63K12-0185). In the same year, ground HLEM and magnetic surveys were completed on the NER 1 grid (AF 63L09-0402) and bore hole PEM surveys were completed on drill holes FORM-1 to -3 (AF 63K12-0189). Between 1995 and 1996, Hudson Bay completed drill hole NER-145 on the NER 28 grid (S-99617) to the southeast of the showing (AF 63K12-0193). The hole failed to intersect significant values. In 1996, Hudson Bay completed a ground HLEM survey on the NER 1 grid (AF 63L09-0411).
