MINAURUM REPORTS ROBUST METALLURGICAL RESULTS AT ALAMOS SILVER PROJECT: RECOVERS UP TO 94% SILVER AND 96% GOLD
Minaurum Gold Inc. has released positive preliminary metallurgical testing results from composites of core samples taken at the Promontorio and Europa targets at its 100-per-cent-owned, fully production-permitted Alamos silver project in the state of Sonora, Mexico.
Highlights:
- Confirms high-grade silver and gold recoveries, even with low-grade material exhibiting impressive recoveries from flotation;
- Six separate composites from Europa and Promontorio vein zones were tested;
- Silver recoveries ranged from 83.5 per cent to 94.3 per cent for five of the six core composites;
- Gold recoveries ranged from 68.9 per cent to 96.5 per cent in five composites with detectable gold;
- Two separate independent labs conducted the tests.
"These metallurgical results from sulphide-bearing mineralization show excellent silver and gold recoveries and represent another derisking milestone at the Alamos silver project," stated Darrell Rader, president and chief executive officer of Minaurum Gold. "We plan to continue refining the metallurgical results and optimize recoveries through added wash times, additional circuits and the adjustment of reagents."
The composite samples were designed to test and provide guidance on potential recoveries from at least two of the high-priority, high-grade silver target zones: Europa and Promontorio. Six separate composites were prepared, including three from core samples at the Europa vein zone and three from core samples at the Promontorio vein zone. For each vein zone, the three composites comprised one-quarter cores corresponding from sample intervals with silver assays in ranges 150 to 250 grams per tonne silver (low grade), 250 to 450 grams per tonne silver (medium grade) and greater than 450 grams per tonne silver (high grade).
The Tecnologico de Metalurgia lab received low-grade and high-grade composites from Promontorio and a medium-grade composite from Europa, while the Servicio Geologico Mexicano (SGM) lab received low-grade and high-grade composites from Europa and a medium-grade composite from Promontorio. In addition, the SGM lab performed a rougher test on a composite of two channel samples taken across a low-grade vein exposure in a crosscut in the Promontorio mine. Copper, lead and zinc recoveries were more variable. Results of the labs' tests are summarized in the attached table.
The results in this news release will assist in refining future advanced metallurgical work to define the existing and additional high-grade silver target vein zones at the Alamos project.
Benjamin Clingan, a metallurgist with more than 40 years of experience, including advisory roles with Pan American Silver at the Dolores and Escobal mines, reviewed the test results.
Flotation tests were performed on composites of core samples at two metallurgical testing laboratories, Tecnologico de Metalurgia of Hermosillo, and the testing lab of the Servicio Geologico Mexicano (Mexican Geological Survey) in Chihuahua.
Minaurum Gold is a Mexico-focused explorer concentrating on the high-grade, 100-per-cent-owned, fully production-permitted Alamos silver project in southern Sonora. Minaurum is managed by one of the strongest technical and finance teams and will continue its founders' legacy of creating shareholder value to develop and acquire a pipeline of potential Tier 1 precious metal projects. Through a portfolio containing silver projects totalling 37,928 hectares, gold projects totalling 25,933 hectares and copper projects totalling 12,856 hectares, Minaurum provides significant exposure to precious metals and base metals.
