Lecture: Melt inclusions of native-silver and native-bismuth at Cobalt, Ontario. Model for native-metal enrichments comparing natural samples with experimental and in-situ studies  

Cobalt, Ontario is renowned for the 12.6 billion grams (445 million ounces) of silver produced from the area since its discovery in 1903. Based on our studies of natural and synthetic systems we are able to formulate a new model for silver transport, deposition, and enrichment based on immiscible systems of molten precious metals and hyper-saline brines. These observations are consistent with silver inside these solid-silver inclusions melting at approximately 300 to 350 °C.
