Deloro Mine collection. Additions. -- 1917-1959. -- 24 cm of textual records. -- 8 photographs.

Biography / History

Mining in Deloro began in 1868 when gold was discovered. In 1873 Canadian Consolidated Gold Mining Company, a British-based company, began mining operations which eventually failed due to the poor recovery of gold. In 1896 Canadian Gold Fields Company bought the property and the first mill was built. The operations were successful in the beginning as new cyanide technology was used to extract the gold and roasting furnaces were built to remove the arsenic from the gold. The mill was closed in 1903 due to the poor grade of the gold.
