Exploration History

1917: Four claims were staked after the initial discovery. 1917-1920: Stripping and trenching was carried out by Ontario Barium Company Limited and a shallow shaft was sunk on the Creek Vein. 1933: H.D. Glendinning extracted a 1/2 ton sample for testing. 1940: A trenching and sampling program uncovered 3 veins. 1959: Independent Mining Corporation Limited completed 3289 feet of diamond drilling. 1969: Extender Minerals of Canada Limited began developing a mine on the property. 1978: Extender Minerals conducted a stripping program to explore for veins between the known veins. 1997: Extender Minerals conducted a trenching program to search for the westward extension of a vein previously mined on claim GG4223. 2001: Extender Minerals completed a study to assess the beneficiation of the Creek Vein. 1969-2003: Extender Minerals mine in production.

Geology Comments

Dec 07, 2005 (D Guidon) - The deposit is contained in Gowganda Formation interbedded greywacke-conglomerate and arkose of the Cobalt Group, part of the Huronian Supergroup. The beds dip gently to the east. The Mistinokan Lake Fault lies, within Mistinokan Lake, to the east of the deposit, and strikes northeast. The fault separates Gowganda formation sedimentary rocks from granitic rocks of the Round Lake Batholith. Barite veins strike 287 and dip 80 degrees to the north. Veins are up to 25 feet in width but average 5 and up to 900 feet in length. Barite content ranges from 25 to 95%.

Lithology

Lithology Comments

Dec 07, 2005 (D Guidon) - Greywacke-conglomerate is the wallrock exposed on surface. It contains a low to moderate content of angular pebbles, mainly of coarse-grained pink granite. Matrix is either a dark greenish-grey or a dusky red. Along the Asbestos Mine Road, immediately west of the bridge, reddish-brown hematite stain can be found. The alteration is stains only some of the beds in the rock. Beds of arkose have been intersected in diamond drill holes. They are fine- to medium-grained and pink. In places they have been so recrystallied that the rock looks ganitic.

Mineralization

Mineralization Comments

Dec 07, 2005 (D Guidon) - Barite veins strike 287 and dip 80 degrees to the north. Veins are up to 25 feet in width but average 5 and up to 900 feet in length. Barite content ranges from 25 to 95%. Traces of calcite, quartz, chalcopyrite and finely disseminated hematite are fround in the vein. Barite varies in colour from white to tints of grey, purple, and brown and in some places shows faint colour-banding parallel to the walls. In the Creek Vein, hematite content can range up to 30 per cent. Samples from the surface dump near the Creek Vein conatined botyoidal hematite.
