Castle Silver Resources Inc. is focused on the exploration and development of former high-grade silver and cobalt mines in the Cobalt Camp in northern Ontario where more than 500 million ounces of silver and millions of pounds of cobalt were mined in the 1900s. Castle’s properties include the Castle Silver mine near Gowganda and the Beaver and Violet mines near Cobalt.
Recent exploration resulted in a new discovery at the Castle property, as drilling intersected 188.8 ounces (6,476 grams)/tonne silver and 1.44% cobalt. Preliminary metallurgical tests showed excellent silver and cobalt recoveries (98.5% and 70.5% respectively) and concentrate grades (11,876 g/t Ag/t and 10.5% Co). Additional testing is underway for optimization of grind and reagents.
The focus of past mining in the Camp was on high-grade silver veins and largely ignored the high-grade cobalt veins that had low-grade silver in them. Castle started developing its properties more than six years ago and is far ahead of others that recently purchased properties in the Camp for their cobalt value. Castle has First Nations agreements in place for exploration and a new mill and also permits for exploration including from underground via an adit used for previous mining. It also has a detailed computer model of all previous drilling results and mine workings.
