Barry Hollinger Mine (Past Producer)
LOCATION: Approximately 10172 miles south-southeast of Kirkland Lake, in lot 3, concession VI and SE’/i, Ny2, lot 4, concession VI, Pacaud Township. Shaft in NW1A, NV2, lot 3, concession VI (patented claim L17930). Latitude 48.01 0, Longitude 79.920 . Map reference: ODM 1957-4, Boston Township and part of Pacaud Township.
The Pacaud Fault, assumed to strike south- east through the center of the property, separates sheared and altered tuffs and tuffaceous sediments on the southwest from Keewatin mafic lava flows to the northeast. These rocks are intruded by a hornblendite-serpentinite sill in the northeast corner of the property and by small masses and dikes of syenite porphyry. Twelve veins have been found on the property but underground development and mining was confined to the No.7 Vein. It strikes N570E, dips 700S, is up to 8 feet in width, and consists of parallel vein- lets or irregular lenses of quartz in a green schist. Mineralization includes pyrite and some chalcopy rite and visible gold. The presence of gold is largely dependent on the quartz and seems to be associated with the presence of chalcopyrite rather than pyrite.
1917-1918: Trenching, two-compartment shaft to 215 feet, and at least 300 feet of lateral development on levels at 100 and 200 feet. Approx imately 500 ounces of Au produced in 50-ton mill. Work by Patricia Syndicate.
1919: Mine buildings destroyed by fire.
1925-1936: Shaft deepened to 1,000 feet, winze from 1,000-foot level to 2,250 feet and 23,581 feet of lateral development on numerous levels. Small test mill, operated during 1925-1926, was replaced by a 150-ton mill in 1926. Continuous production from 1925 to 1936. Work by Barry- Hollinger Gold Mines Limited.
1944-1946: Mill cleaned up.
1962: Two diamond-drill holes (405 feet) by A. Bargnesi.
1969-1970: Trenching and one diamond-drill hole (110 feet) by A. Bargnesi.
