Gold Recoveries In Preliminary LP Fault Metallurgical Tests

VANCOUVER - Great Bear Resources Ltd. reported gold recovery test results from its flagship Dixie Project, in the Red Lake district of Ontario.

Chris Taylor, President and CEO, said, "We selected what were anticipated to be the 'most difficult' mineralized domains to extract gold from at the LP Fault, and are pleased to report very high gold recoveries at all grades. This has strong positive implications for the future development potential of the Dixie project. Similar very high gold recoveries from the Dixie Limb and Hinge zones using comparable grinding and cyanidation protocols indicates mineralized material from all gold zones is likely amenable to processing through the same extraction circuits.  Initial LP Fault cyanidation gold recovery tests confirm that non-refractory, free gold dominates all low to high-grade domains tested to-date. All Dixie gold zones have excellent potential for significant gravity circuit gold recoveries, which will be investigated in the next phase of metallurgical testing."

Ten one kilogram representative samples were analyzed at Blue Coast Research Ltd. ("Blue Coast") of Parksville, British Columbia (Table 1). Samples were composited from 10 to 13 meter long core intervals and were processed through a standard 48 hour bottle roll procedure at 40% solids, using a 1.0 g/L sodium cyanide solution. All tested combinations of grades, host rocks, sulphide content and alteration styles recovered a very high percentage of total gold, within a four percent range from 95.2% to 99.2%. While high-grade gold samples recovered the highest percentage of total gold during cyanidation, sub-gram low-grade gold mineralization nonetheless achieved excellent recoveries of greater than 95 percent. LP Fault gold mineralization is not refractory. All samples, regardless of grade, were described as "free-milling", indicating gold is not encapsulated in sulphide accessory minerals. Free gold mineralization has repeatedly been observed and reported by Great Bear, including during petrographic/microscope analysis.
