FREEMAN GOLD INITIATES LEMHI 2021 METALLURGICAL PROGRAM - BUILDS ON HISTORICAL HIGH LEACH RECOVERY RESULTS
Freeman Gold Corp. has commenced metallurgical testwork on its 100-per-cent-owned Lemhi gold project located in Idaho, United States. This work is part of Freeman's integrated technical program to advance toward a production decision. A comprehensive review of the historical information and testwork conducted by previous operators has been completed. Freeman's metallurgical team has designed a testwork program to follow up and enhance gold recoveries, ultimately leading to a project flowsheet for the Lemhi project. The company is utilizing samples from both historical and fresh drill core from the 2020 exploration drill program.
Will Randall, president and chief executive officer, commented: "We have a very strong foundation of metallurgical testwork from previous operators of the Lemhi project which indicate excellent recoveries using conventional leach technologies. This body of work has saved us considerable time and money in designing a metallurgical program that will provide an optimal process and recovery parameters at Lemhi. As part of our 2020 drill campaign, we completed a large diameter diamond drill hole, providing us valuable material for the testing program which will be conducted at SGS Canada."
A review of metallurgical evaluations by previous owners of Lemhi has shown that gold recoveries respond well to conventional processing techniques. Past engineering studies has also shown that Lemhi has the potential to be developed into an open-pit, heap and/or tank leach operation.
Historical testwork focused primarily on cyanide leaching, most recently in the mid-1990s, by Kappes Cassiday & Associates (KPA) of Reno, Nev. Column leach tests by KPA to evaluate heap leach potential showed gold recovery ranged from the 70-per-cent to 90-per-cent range, with best results obtained using a crush size of 80 per cent minus eight mesh (2.4 millimetres (mm)). Additional work by KPA included bottle roll testing to simulate tank leaching response that typically resulted in optimized gold recoveries in the mid-90-per-cent range. The results vary based on the head grade and lithology of the samples, along with test conditions used, most notably particle size and leach retention time. In general, the historic metallurgical information shows good to excellent leach response over wide spatial areas and depth of the known gold mineralization.
In order to advance process development at Lemhi, a 2021 metallurgical testing program is to be conducted at SGS Canada Inc., Burnaby, B.C., under the direction of Frank Wright, professional engineer. This study will continue to focus on leach response, as well as investigate optional procedures, including froth flotation, primarily for deeper less oxidized material, and for establishing design and operating parameters for crushing, grinding and leaching circuits.
The technical content of this release has been reviewed and approved by Dean Besserer, professional engineer, vice-president of exploration for the company and a qualified person as defined by National Instrument 43-101.
About Freeman Gold Corp.
Freeman Gold is a mineral exploration company focused on the development of its 100-per-cent-owned Lemhi gold property. The Lemhi project comprises 30 square kilometres of highly prospective land. The mineralization at the Lemhi project consists of shallow, near-surface primarily oxide gold mineralization that has seen over 355 drill holes but remains open at depth and along strike. The company is working toward derisking the asset and producing a maiden National Instrument 43-101-compliant resource estimate as a result of both brownfield and greenfield exploration.
