Photographs and documents from the Silver Islet Mine and Silver Islet Store, including ledgers and a chart.

A rich deposit of silver was discovered on Silver Islet in 1868. A small island at the tip of the Sibley Peninsula, the mine was built deep below the waterline, and relied on breakwaters and pumps. Silver Islet was mined until 1884, when pumps failed, and the mine was flooded. The small community built on shore to support the mine is still inhabited.
