Point Location Description: Shafts, trenches.

Location Method: Conversion from MDI

Access Description: The prospect is located in Priske Township about 5 km east of Schreiber near the western shore of Hays Lake, about 3.2 km north of Highway 17 (claim TB 3412, claim map G 631, Priske Township). Access may be gained via the road leading to Hays Lake which branches off the Trans Canada Highway just east of Schreiber. This road is also access for the Gold Range Prospect. The workings are approximately 350 m west of the western shore of Hays Lake.

Exploration History

1872: Exploration began in the area. 1896: Gold was discovered on M.L. AL217. Five veins were discovered but only 1 was worked. 1898: Two shafts were sunk 366 m apart, to depths of 10.4 m and 9.15 m. 1917-1934: Claims were patented; additional surface work performed; additional claims were staked. 1936: All interests transferred to the Canada Mining Co. Ltd. Otisse Longlac Gold Mines was incorporated in June, succeeding the dormant Otisse Mining Company, and acquired 16 claims and discovered a new zone 12.2 m wide x 76.2 m long. Trenching was done on a mineralized conglomerate zone. The 'Main Ledge' vein was estimated to be 1524 m long x 1.8 to 3.6 m wide. 1937: Surface work performed by 7 men. 1938 J. Crookston channel sampled the “Main Ledge” vein. 1939: The property was examined and sampled by Sylvanite Gold Mines Ltd. A report was submitted by G.L. Holbrook who discounted the economic viability of the prospect. 1940: The unpatented claims were cancelled. 1941: Diamond drilling was done (footage unknown). Parts of the ground were restaked. 1942-1970: The ground changed hands several times. New Otisse became inactive and had its charter cancelled in 1952. 1979: The shafts were covered. J.C. Archibald staked 5 claims adjacent to the patents, and performed a mag and EM survey on one of his claims. 1980: Lormac Exploration Ltd. took over the patented claims from C.W. Archibald and the claims of J.C. Archibald. VLF-EM, mag and geological surveys were done. The VLF outlined 3 anomalous zones trending NE-SW across the property. In March, 16 holes totalling 770 m were drilled. 1983: One hole totalling 217 m was drilled in the SE corner of TB467983.

Geology Comments

Dec 07, 2005 (B Nelson) - Holbrook (1939) writes: The claims are underlain by Keewatin greenstone lava flows with interbedded iron formations and conglomerates. These are cut by granite porphyry dykes and it is probably that the low ground underlying the east half of the group covers the NE continuation of the large granite mass occurring on the Gold Range property. The general trend of all the rock is about N35?E. Two showings have been developed on this property, both on claim 3412. The main showing consists of a 30' (9.14 m) or more wide band of iron formation striking N30? 35? with a vertical dip across the northwest part of the claim. The iron formation is intruded along its edge by two parallel dykes of granite porphyry and near its middle by a narrow (2 4 foot) (0.6 1.2 m) irregular dyke of lamprophyre. It is also strongly sheared along its strike and dip and fairly well mineralized by disseminated pyrrhotite, pyrite and some chalcopyrite. A few weak, narrow and irregular quartz lenses also occur in the shearing. The other showing on the property is near the centre of the east boundary of claim 3412. Here shearing carrying small quartz lenses has been opened up by a limited amount of stripping for a length of 50 feet (15.2 m). The shearing and quartz varies in width from 8 inches to 2 feet (20 to 61 cm), strikes N45?E and dips steeply northwest. A thorough channel sampling of this occurrence failed to show any values over 1.60 dwt. (0.08 ounce/ton). There might possibly be an outside chance of developing a small ore shoot along the strike of the iron formation. However, the samples are too low where the zone can be sampled to make further development work attractive. The property is of no further interest unless new showings are found and opened up.

Mineralization Comments

Dec 07, 2005 (B Nelson) - According to Holbrooke (1939): Good grade values across 8 foot (2.4 m) and 10 foot (3.05 m) widths were reported from sheared iron formation by the owners. It has been developed several years ago by two shafts, one 52 feet (15.8 m) deep and the other 39 feet (4.9 m) deep, 390 feet (119 m) apart, with several shallow pits and trenches where the overburden is not too heavy. These showings were thoroughly check sampled with discouraging results. Only two samples showed assays of interest and these were some 230 feet (70.1 m) apart with several low assays between. Due to water, it was impossible to sample the shafts. The iron formation is well mineralized with disseminated pyrite, chalcopyrite and pyrrhotite, as well as some graphite and galena. Visible gold was noted with considerable pyrite in blue grey quartz. Channel sampling by Holbrooke (1939) returned values ranging from trace to 1.04 oz/ton Au (over 0.30 m). Sampling by Catleugh (1979) for Lormac Exploration Limited returned assays ranging from trace to 0.19 oz/ton Au. The 'Main Ledge' vein was sampled by J.E. Crookston (1938) and returned values including the following: 2.44 oz/ton Au over 30 cm between granite and lamprophyre; 2.16 oz/ton Au over 46 cm between granite and lamprophyre; 0.88 oz/ton Au over 25 cm from quartz vein; 0.73 oz/ton Au over 61 cm from between quartz vein and iron formation; 0.60 oz/ton Au over 61 cm from quartz and iron formation. The lowest values returned 0.01 oz/ton Au.
