95% Gold Extraction from Paymaster Resource Material

 

VANCOUVER, BC - Canamex Resources Corp. has completed initial cyanidation tests on 2014 drill cuttings from the Paymaster resource area at the Bruner gold project, Nye County, Nevada.

Canamex has completed 20 cyanidation bottle roll tests on drill cuttings from the 2014 RC drilling program, composited into mostly 20-ft (6.1 meter) length intervals. These composites represent head grades ranging from 0.005 ounces per ton (0.17 grams per tonne) gold to 1.040 ounces per ton (35.66 grams per tonne) gold, and represent the full range of grade values likely to be included in the upcoming Preliminary Economic Assessment on the Bruner property, based upon drilling results to date. The average head grade of all 20 composite samples was 0.1011 ounces per ton (3.47 grams per tonne) gold and 0.297 ounces per ton (10.18 grams per tonne) silver. All sample preparation, analytical work, and leach tests were performed at Kappes Cassidy & Associates metallurgical laboratory facility in Reno, Nevada.

Average extractions from a 96-hour bottle roll cyanide leach test on -200 mesh material were 95.1% for gold and 41.2% for silver, being very similar to cyanidation bottle rolls tests from the other resource areas (HRA and Penelas) on the property performed previously. Gold recoveries ranges from 85% on very low grade material to +99% on the highest grade material, with an average tail grade of 0.0011 ounces per ton (0.038 grams per tonne) gold, indicating nearly all of the gold in the Paymaster resource area is extractable with cyanide. The mineralized zone is entirely oxidized. Reagent consumption in the bottle roll tests was very low, averaging only 0.08 pounds per ton cyanide and 2.75 pounds per ton lime.

Greg Hahn, President & COO of the Company says, "The Company is very pleased with these initial metallurgical test results at the Paymaster resource area. They indicate nearly 100% extractability of the gold from the mineralized material, and very low reagent consumption, which is similar to results from the HRA and Penelas resource areas, and which should result in low reagent costs in the upcoming Preliminary Economic Assessment. These metallurgical test results are the first step towards moving the Paymaster resources from inferred to indicated status."
