Silver Centre is a ghost town in Timiskaming District, Northeastern Ontario, Canada, situated in South Lorrain Township. It is located approximately 35 km (22 mi) south of North Cobalt, and 3 km (1.9 mi) west of Highway 567. Silver Centre was a secondary camp to the great silver fields of Cobalt, discovered in 1903. There are no current residents in Silver Centre. It is still an active mineral field and does at times have active mineral exploration.
The first discovery of silver in the area was made in the 1874 by a lumberman named Pat Manion. He blazed a stump as a witness or discovery tree and showed his sample to his fellow workers at the bunkhouse; everybody believed the sample to be common lead, and Manion agreed. A decade later while discussing his find to a young geologist, Manion quite surprised, discovered that the sample was nearly pure silver. Manion returned to the Ryan Timber Limit where he searched in vain for the location, but was unsuccessful in his attempt. The story of Manion's lost silver mine became legendary throughout the Gatineau-Ottawa region. In August 1903 silver was quickly discovered near the railway bed during the construction of the Temiskaming & Northern Ontario Railway. The discovery made at Long Lake, 103 mi (166 km) north of North Bay, was spectacular. And within one year a silver rush occurred and subsequently the town of Cobalt was established to cater to the world's greatest silver region.
The South Lorrain camp produced the Keeley "nugget", which weighed 4,402 pounds and contained 24,222 ounces of silver.
