The Leitch Gold Mine - (now on Goldsone (Roxmark) land)
was the # 1 of Ontario & Canada's Gold producers
richest highest grade of gold and most profitable Gold mine -
producing 860,648 ounces from 906,395 tons of ore
at an average recovered grade of 0.91 oz.Au/ton.
Even more impressively, the average recovered Gold grade -
over the last ten years of the mine’s Gold operation -
was 1.15 oz.Au/ton.
The Leitch Mine was once Canada's richest.
The Sand River/Leitch complex produced more than 900,000 ounces of gold.

History
A past producer within the Eva Township, the Leitch Mine property was first staked in 1901. Exploration for iron was conducted on its claims by a number of companies between 1910 to 1923. Finally, in 1934, R. and J. Cryderman prospected the strike extension of the Sand River Mine's No.1 vein which lead to the discovery of the Leitch's No.1 vein.
Leitch Mine became one of the richest gold producers in Canada, operating continuously from 1937 to 1965, processing a total of 861,982 ounces of gold at an average grade of 0.92 ounces per tonne of ore milled.
Portions of the Leitch dump continuted to be milled throughout the 1980's. The Leitch Mine was serviced by a three-compartment shaft to 3,006 feet, with a winze from the 19th or 2,875-foot level to the 30th level.
Current operations
In 2003, Roxmark acquired from Teck Cominco Limited an approximate 63% interest in the Leitch property, consisting of 10 patented claims covering 1,276 acres in Eva and Summers Townships. The property is governed by a Joint Venture agreement dated June 30, 1987 between Teck and San Paulo Exploration Inc., now AdvanteXCEL.com Communications Corp., as amended April 30, 1990 and October 30, 1990. The other Joint Venture party holds the balance of approximately 37%. Roxmark is the operator.
Furthermore in 2003, Roxmark acquired from Kinross Mines a 55.25% interest in the East Leitch Property covering 20 claims held under a 21-year lease on 832 acres in Summers Township. The property is governed by a Joint Venture Agreement dated September 1987 between Falconbridge Limited (now Kinross) and Minerals Anodor Inc. (now Afri-Can Marine Mineral Corporation). In January 2005, Roxmark acquired the remaining 29.75% interest from African Marine.
In 2009, Roxmark acquired the remaining 27% interest in the Leitch property. Roxmark mines now owns 100% interest.
