Corvus Gold Achieves High Gold Recoveries in Large Diameter Column Tests at North Bullfrog Project, Nevada
Corvus Gold announces the results of its initial large diameter column leach testing of oxide resource materials from its 100% controlled North Bullfrog Project near Beatty, Nevada. The leach columns, which were testing coarse crush material (2 inch minus) from the Sierra Blanca and Jolly Jane areas (representing over 80% of the existing oxide resource), returned encouraging results. Average gold recovery for large diameter column tests for the Sierra Blanca area was 70% and 64% for the Jolly Jane area, which support an overall Run of Mine recovery plan (Table 1). The Company’s concept of using Run of Mine material for heap leaching of gold could significantly lower capital and operating costs at the project. A preliminary economic assessment (PEA) is expected to be completed next month, which outline more specific project economics.
Jeff Pontius, CEO of Corvus, stated: “These initial large diameter column test results are confirming the potential at North Bullfrog for a low unit cost, heap leach operation. These encouraging recovery results coupled with a highly favourable, low strip, surface mining geometry and nearby infrastructure greatly enhance the project’s development potential. Corvus is encouraged by these results and will aggressively advance the North Bullfrog project to assess its potential to transform the Company into a future gold producer.”
