Gravity recovery alone captures an impressive 38.1% of Au and 10.5% of Ag. This indicates that a processing scheme employing early gravity recovery should produce considerable Au in the form of dore bars. Gravity recovery is generally the cheapest means of Au recovery in the mining industry.
Pb-flotation concentrate generated after gravity gold testing captures an additional 52.5% of Au and 62.6% of Ag bringing recovered Au to 90.6% and Ag to 73.1%. Importantly, the mass pull to generate this Pb concentrate is 7.7%, or 13-to-1, a favorable outcome. Also favorable, this Pb-concentrate product grades approximately 2 opt Au, 55 opt Ag and 12.9% Pb, a clear indication that precious metal-rich concentrates can be made from Surebet mineralization. Such precious metal-rich concentrates are considered marketable to a large audience of smelting operations in

Final testing to produce a Zn-flotation concentrate captures an additional 7.6% of Au bringing overall Au recovery to 98.2%. An additional 13.3% of Ag is recovered bringing total Ag recovery to 86.4%. The mass pull for the Zn concentrate, 18.2%, or 5.5-to-1, is significantly higher than that of the Pb concentrate, and resulting Au and Ag grades are significantly lower. More work is needed to determine if a lower mass pull, higher precious metal grade can be achieved in Zn-flotation or bulk flotation concentrates.
The Bond's Work Index ('BWI'), a measure of energy needed to grind rock during milling, is a moderately low 12.25 kw-hr/tonne for Surebet mineralization. Many gold projects see a BWI significantly higher, +14 kw-hr/tonne. This bodes well for reduced power consumption and milling costs for the project.
Gravity and flotation methodologies are standard in the mining industry. Capitalization and operational costs of a mill encompassing a combined gravity-flotation scheme are relatively low when compared to more complicated technologies used by many other precious metal operations. Eliminating the need for CN could result in environmental advantages for Surebet. Goliath is extremely pleased with these initial metallurgical results and anticipates conducting further metallurgical testing as Surebet progresses.
