Freeman Gold Corp.(TSXV: FMAN) (OTCQX:FMANF) has received positive final results from the comprehensive 2021/22 metallurgical testing program conducted on the Lemhi Gold Deposit, located in eastern Idaho, USA.
Expanding from previous work, the metallurgical test work has now been completed to a level to allow its inclusion into a Preliminary Economic Assessment (PEA). Gold cyanidation extractions averaged 95%, based on 38 variability samples, with head grades ranging from 0.2 g/t to 10.9 g/t Au, and averaging 1.02 g/t. Samples were collected over a large spatial area considered representative of the 2020 maiden mineral resource.
The results are based on moderate process operating conditions that are suitable for a conventional carbon in pulp (CIP) tank leaching process. This includes a grind of 80% passing particle size (P80) 106 microns, with a leach retention time of approximately 36 hours, following gravity pre-treatment.
“Our completed metallurgical programmne has confirmed excellent gold recoveries over a large spatial area representative of the Lemhi resource estimate,” Executive Chairman, Paul Matysek, said.
“Furthermore, metallurgical samples collected at depth provided consistent and similar recoveries as those near surface. This bodes very well for our current drill program as we look to build oxide gold ounces on strike and at depth.”
Frank Wright, P.Eng., Freeman’s independent consulting metallurgist of F. Wright Consulting Inc., said the metallurgical programme at Lemhi has consistently provided gold recoveries in the mid to upper 90% range throughout much of the resource and is now at a stage to support a preliminary economic assessment for the Project.
In conclusion, the results suggest that Lemhi is well suited with respect to metallurgical response for project advancement, based on the current open pitable mine resource grade.
