The Past Producing Mine
The Manibridge Mine was an underground nickel mine, operated by Falconbridge Nickel Mine Ltd (now Xstrata) between 1971 and 1977. The mine had a mineral inventory of 1,409,000 tons (including 15% dilution) at 2.25% Ni, 0.27% Cu to a depth of 1250 feet and recovered grades (including smelting and refining losses) of 1.65% Ni, 0.125% Cu and 0.02% Co. The operation ran into continual problems, never reaching design production levels (250,000 t.p.y. milled and 13,700,000 lbs Ni).
The surface buildings were all removed and a comprehensive mine closure plan has been followed, site rehabilitation was completed and post closure environmental monitoring continues.
Crowflight Joint Venture
In 2007 Crowflight Minerals Inc. and Pure Nickel entered into a 50-50% joint venture to explore for and develop nickel deposits on properties controlled by both parties.
2008 exploration resulted in the discovery of two new zones of mineralization located within 400 metres of the past-producing ore body; confirming an extension of the deposit itself at depth. Six holes were drilled for a total of 2,496 metres. Downhole EM surveys were conducted on each drill hole. The table below summarizes results from this year's drilling program.
In 2011 the joint venture was dissolved and the claims reverted back to the original owners.
Highlights of the program include:
