Exploration History

1934: Martin McNeeley Mines Ltd. carrie dout trenching and surface exploration. 1936: Luxor Red Lake Mines was incorporated to acquire the property formerly held by McNeely Red Lake Holdings Ltd. 1937: Trenching and pitting. 1 DDH totalling 84.4 m was drilled on claim KRL 2208. 1962: Luxor Red Lake Mines conducted EM and magnetometer surveys and drilled 3 DDH. 1965: Luxor Red Lake Mines drilled two diamond drill holes totalling 536.1 m. 1981-84: Bluestack Resources Ltd. optioned the property and carried out geophysical, geochemical, and geological surveys.

Lithology

Lithology Comments

Dec 07, 2005 (K R Kettles) - The occurrence is underlain by a sequence of clastic sedimentary rocks which are overlain by an interlayered sequence of mafic flows and oxide and sulphide facies iron formation. The clastic metasedimentary units have been intruded by several quartz-feldspar porphyry dykes. The area immediately west of the occurrence is underlain by a large feldspar and quartz-feldspar porphyry intrusion. High silver values occur in what appear to be skarn rocks. The skarn rocks consist mainly of oxide and sulphide iron formation which contain appreciable amounts of epidote and garnet.

Mineralization

Mineralization Comments

Oct 31, 2014 (K R Kettles) - Sulphide facies iron formation units contain up to 55% py and po. High silver and copper values have been obtained from several of the sulphide facies iron formation units. One section of drill core 0.7 m in length returned assays of 0.04 oz/ton (1.371 g/tonne) Au, 0.95% Cu, and 0.86 oz/ton (29.485 g/tonne) Ag. A 0.24 m section of core returned assays of 0.06 oz/ton (2.057 g/tonne) Au, 3.50% Cu, and 1.12 oz/ton (38.399 g/tonne) Ag. 1965 Luxor DDH-65-2 returned an assay of 0.04 oz/t Au, 0.95% Cu, 0.86 oz/t Ag over 0.7 m; 0.06 oz/t Au, 3.5% Cu,1.12 oz/t Ag over 0.24 m, 29.32% Fe in skarn (417.8-452.4 ft)

Nov 15, 2022 (Therese Pettigrew) - Timiskaming conglomerates and greywackes are cut by granodiorite and quartz dykes, and quartz veins varying from 1-8 feet in width which contain pyrrhotite, chalcopyrite, pyrite, and small amounts of gold. Malachite and native copper occur in a weathered portion of the outcrop. The best intersection was between 717.7 and 718.5 feet in an inclined hole L-65-2 collared on KRL 2206. This interval, located below lake level on claim KRL 49364, contained narrow stringers of pyrrhotite and chalcopyrite in metasediment with cherty bands. Assays results are 3.50% Cu, 1.12 oz/t Ag, and 0.06 oz/t au. an assay of 29.3% Fe was obtained from 417.8-452.4 feet in siliceous skarn zones containing magnetite (SMDR 00542)

Alteration Comments

Dec 07, 2005 (K R Kettles) - The metasediments in the area contain many thin quartz-carbonate and quartz-tourmaline veins. The oxide facies iron formation (skarn rocks) have been highly altered, and contain up to 80% epidote, some garnets and chlorite.
