Exploration History

1936: Sanshaw Mines drilled 15 diamond drill holes totalling 1160 m. 1937: Sunk a shaft to 30 feet. 1939-1940: McKenzie Red Lake Gold Mines drilled 4 holes totalling 350 m. 1946-1947: Orlac Red Lake Mines sank shaft to 137 m. Levels established at 67.5 m and at 112.5 m. 690 m of development on these levels. 1953 to 1977: Name of company changed, sold 80% to Cable Mines and Oils Ltd., property ended up with St. Fabien Copper Mines Ltd. who sold 85% to Xtra Developments. 1979-80: Bonanza Red Lake Mines options property and completes geophysics EM, magnetic and gradient surveys), and 7 diamond drill holes totalling 1030 m. 1987: Pure Gold resources carried out exploration on behalf of Noramco Mining Corp. Surface sampling, IP, VLF and magnetometer surveys, drilling 48 DDH for 6637 m. 1988-89: Noramco drilled 34 holes for 4785 m. 2003: Wolfden Resources Inc and Lateegra Resources Corp entered joint venture and completed a magnetometer survey, surface mapping, sampling and 5 DDH for a total of 625 m on Whitehorse Island. 2004: New joint venture between Red Lake Resources and Grandcru Resources Corp. drilled 7 DDH for 1020 m and conducted magnetometer survey over ice. 2006: Grandview Gold Inc optioned the property and conducted a magnetometer survey. 2008: Grandview completed 5 DDH totalling 991 m but only 3 produced core. 991 m and only 2 reached targets. 2012: Grandview conducted an IP survey. 2015: Grandview delisted from the NEX stock exchange, sold its assets and was renamed to Pudo Inc.

Geology Comments

Dec 07, 2005 (K R Kettles) - The prospect is located along the eastern contact of the Dome granite-granodiorite stock and the adjacent felsic volcanics. The prospect is underlain by a broad zone in which the granodiorite stocks of the Dome Stock, and the adjacent volcanics have been variably fractured, sheared, and hydrothermally altered. Gold mineralization occurs in narrow irregular lenses of intense alteration, fracturing, and quartz veining within this broad zone of deformation and alteration. The auriferous lenses strike north-south, and dip 80 degs E. The granodiorite-volcanic contact strikes N20 degs E and dips 78 degs W. The auriferous lenses occur in a narrow volume of rock 102 m in length, varying from 3 to 7.5 m in width and extending downward to the granodiorite-volcanic contact. No auriferous lense have been discovered in the fractured and altered volcanic rocks.

Mineralization

Mineralization Comments

Dec 07, 2005 (K R Kettles) - The auriferous lenses have highly variable geometries, and dimensions. They consist of irregular zones of silification adjacent to fractures in altered granodiorite, and irregular zones of altered granodiorite containing cherty blue grey quartz stringers. The best gold values occur in association with these cherty quartz stringers, either in the cherty stringers, or in the adjacent silicified wall rocks. Minor amounts (<1%) of sulphides are associated with the gold, Jamesonite?, and stibnite?. Late, and barren quartz-tourmaline veins, stringers, and small masses occur in close association with the auriferous lenses.

Apr 28, 2016 (Therese Pettigrew) - In 1979, Bonanza Red Lake Explorations Ltd. conducted geophysical surveys and drilled six holes. The best intersection was reported from hole B79-1, which returned 0.159 oz/t over 17.02 feet (4.95 g/t Au over 5.2 m). Hole NBZ-88-10 drilled by Pure Gold Resources in 1988 graded 4.53 g/t over 26 m, with a 5.5 m interval grading 13.65 g/t, 3.3 m grading 22.22 g/t, and 2 m grading 34.94 g/t (AFRO 2.39778).

Alteration Comments

Dec 07, 2005 (K R Kettles) - In the immediate vicinity of the prospect , the feldspars in the granodiorite have been altered to sericite and carbonate, and the hornblende has been chloritized. In the auriferous lenses, the altered granodiorite has been silicified.
