Geological Details
The Amisk Gold Syndicate Showing or the AGS Showing consists of mineralized zones located on the west side of a narrow peninsula on the northeast side of Amisk Lake. The showing is exposed 12 trenches and 2 shafts. The showing host rock is a fine-grained, massive, greywacke. At the showing, the greywacke is sheared, sericitic, carbonatized (ankerite and minor calcite as fine disseminations and veinlets) and silicified. The showing follows a sheared contact between Amisk Group volcanics to the west and greywackes to the east. Locally, the rocks which strike 170° and dip 70°W form part of an overturned limb of an isoclinal fold. The zone trends 173° and dips 29 to 48°SW. The main mineralized zone, which follows the western shore of the peninsula for about 3,000 ft (914.4 m) from the peninsula tip, is overlain by a gossan that can be up to 20 ft (6.1 m) deep. The auriferous portion of this zone has a strike length of 400 ft (121.9) m and a width of 15 ft (4.6 m) The mineralization consists of disseminated pyrrhotite, native gold, chalcopyrite, sphalerite, and galena in minor amounts with arsenopyrite and pyrite in slightly higher abundances. Gold is erratically distributed and the grade is sub-ore. The gossan assayed 0.28 oz/ton on assay. A sample of fresh rock underlying the oxidized material returned 0.43 oz/ton Au. The principle ore was reported to be arsenopyrite. Cyanidation tests gave 90% recoveries. Between 1981 and 1982, SMDC sampled and mapped the zone in 3 uncaved trenches. In trench A, the zone orientation is 009°/34°NW. The orientation in trench B 015°48°NW and the orientation in trench G is 173°/29°NW. The four samples collected returned the following values: SAMPLE OZ./TON PPM PPM SAMPLE NUMBER AU AU AS LOCATION _________________________________________________________ AL20-3007 ----- 1200 700 Trench B (south shaft) AL20-3010 ----- 12 200 AL20-3021 0.072 ---- 1300 Trench B - gossan AL20-3022 0.117 ---- 1300 Trench G - gossan Starting in 1989, Cameco completed a series of holes to test the zone. In 1998, Claude Resources completed further drilling in the immediate area of the zone.

Exploration History
12/1/2023 (From Saskatchewan Exploration and Development Highlights 2023, Table 4, p.12) 12/1/2024 (See Reserves/Resources, from Saskatchewan Exploration and Development Highlights 2024, Tables 6-7, p.12-13) 8/2/1988 The property was first staked in 1928 by G. Chatten. In 1930, he transferred the claims to Amisk Gold Syndicate. Between 1932 and 1936, the showing was within the JUNE claim group. Amisk Gold Syndicate completed a series of trenches and sunk a 6 ft X 10 ft adit (named the Victory Adit) to a depth of 114 ft (AF 63L09-0089) on the "Amisk Lake Gold Mine". Between 1936 and 1960, the showing was covered by E. J Hansen VICTORY claims Nos. 1 and 2 or S-3050 and S-3051. During this period, Hansen completed 8 trenches on VICTORY claim 2 to expose the mineralization. 8 drill holes totalling 1050 ft (320 m) were completed and and two shafts; one to the north (on VICTORY claim No. 2), 125 ft (38.1 m) deep on an incline of 45° with a short crosscut at 105 ft (32.0 m), and one to the south 20 ft (6.1 m) deep (on VICTORY claim No. 1). The two shafts are 225 ft (68.6 m) apart (AF 63L09-0056). During the same period of time, Hansen completed 1 trench and 6 drill holes on the east side of Tarrington Island near the north tip of the island (VICTORY claim No. 1, 1 trench to the north of the showing on VICTOR claim No. 3 and 3 trenches to the west of the showing on VICTORY claim No. 6. By 1972, the showing was within LUCKY claim No. 4. Hudson Bay Exploration completed ground turam and ABEM surveys over the claim (AF 63L09-0185). In 1977, SMDC completed a ground reconnaissance that covered the showing. By 1980, the showing area was covered by ML 5275. In 1980, SMDC completed EM-17 and magnetic surveys over the property (AF 63L09-0242). In the same year, J. Pearson geologically mapped the property for the Province of Saskatchewan. Between 1981 and 1982, SMDC detail mapped the showing, sampled the existing trenches and completed a ground EM survey over the immediate showing area (AF 63L09-0285). In 1985, SMDC completed a single line biogeochemical survey over the showing (AF 63L09-0311). In 1987, SMDC completed ground VLF-EM and magnetic surveys over the showing (AF 63L09-0337). In 1989, Cameco completed drill holes 3AL9-204 to -207 on the AGS Showing (AF 63L09-0357). The better intersections are reported above. Claude Resources Inc. optioned Cameco's Laurel Lake and Missi Island properties. In 1998, Claude completed geological mapping, prospecting, and a ground magnetic survey on ML 5275 and drill holes PAM98-1 to PAM98-7 to test conductors immediately adjacent to the Amisk Gold Mine or Victory Adit (AF 63L09-0437). Between 1997 and 1998, Claude Resources completed prospecting and outcrop and trench sampling in the immediate showing area (AF 63L09-0441).
