Anaconda's Metallurgical Test Work Demonstrates Pine Cove Mile Processing Potential

Anaconda Mining (TSX:ANX) has reported its results of preliminary metallurgical test work that ore from the Thor Deposit of the Viking Project could be processed at the Pine Cove mill using current flotation and leach circuit configuration.
As quoted in the press release:

The results of the study are based on a homogenized sample collected from two diamond drill holes.  Bench scale test work, conducted by NB Research and Productivity Council (“RPC”), primarily focused on flotation, cyanide leaching and grinding to evaluate the response of the Thor Deposit material to the current plant flow sheet for the Pine Cove mill.
In a flotation test, using a grind of (80% passing) 150 µm, currently used for Pine Cove ore, the Thor Deposit sample attained 96.0% Au recovery in 4.4% of the mass at a grade of 35.12 grams per tonne (“g/t”) Au in the rougher stage.  In a bottle roll cyanidation test the current Pine Cove mill regrind size of (80% passing) 20 µm obtained 94.1% Au extraction without requiring accelerating reagents and consumed 1.1 kg/t NaCN  compared to 3.6 kg/t for Pine Cove ore.  A Bond Ball mill grindability test was performed utilizing a limiting screen size of 150 µm and indicated that the sample has a Bond Ball Work Index (“BWI”) value of 18.5 kWh/t.

Dustin Angelo, president and CEO said:

Our primary thesis in expanding Anaconda’s reach to new deposits is that the Pine Cove mill and related infrastructure can be leveraged to expedite development of satellite deposits that would otherwise not be mined, given their size.  The preliminary metallurgical results on flotation and leaching from the Thor Deposit supports our thesis and allows the company to move forward with plans to expand the historical resource base at the Viking Project with the initial goal of doubling the size of the resource while optimizing a path to development.
