Nova Minerals Limited announced that it has received highly encouraging results from its first phase metallurgical test work on mineralization from its high-grade RPM North Deposit in Alaska. Tests were conducted at Bureau Veritas Vancouver to determine the potential for intensive leach of gold contained in flotation concentrate. Results were outstanding with 96.2% of gold recovered.

Concentrate leach recovery was calculated by Bureau Veritas based on gold recovered into solution and gold left in solid tailings. Relatively minor losses can be expected from the electrowinning circuit. Tests were conducted at Bureau Veritas Vancouver to determine the potential for flotation to concentrate gold.

Results were outstanding with 92.4% of gold recovered into a concentrate with 14.3% of the flotation feed mass. A high flotation concentration ratio is important as it allows fine grinding and intensive leaching of a small flotation concentrate, at a reasonable cost. Flotation and leach recoveries were 92.4% and 96.2% respectively.

Combined Flotation and leach recovery is 88.9% using 73 microns in flotation and 16 microns in leaching. Minor losses could be expected.
