Vancouver-based Integra Resources has received positive results from metallurgical testing of samples from its DeLamar and Florida Mountain gold-silver deposits about 160 km from the capital, Boise.<\/p>\n
From six Florida Mountain oxide samples, recoveries of 83.3% gold and 39.7% silver were achieved in bottle roll tests. The same oxide sample composites had 72.4% gold and 23.4% silver recoveries after 23 days of a 63-day preliminary column leach test. Integra says the success of the column flotation tests indicate that the deposit could be successfully heap leached.<\/p>\n
The deeper un-oxidized mineralization from DeLamar will probably be more amenable to flotation. Historical work demonstrated good recoveries in sulphide concentration, fine grinding and cyanidation.<\/p>\n
Integra is working on a preliminary economic assessment for the DeLamar project due out in H2 2019. Several processing options will be considered.<\/p>\n
The inferred resource for both Florida Mountain and DeLamar deposits is 154.5 million tonnes grading 0.45 g\/t gold for 2.27 million contained oz. The silver grade averages 21.92 g\/t for 108.5 million contained oz. The gold equivalent grade is 0.71 g\/t or 3.5 million contained oz.<\/p>\n
The historic DeLamar mine was closed in 1998 after producing 1.6 million oz. of gold and 100 million oz. of Senile.<\/p>\n
