FOR RELEASE: April 9, 2024 TRADING SYMBOL TSX.V: MGG
Minaurum Reports Robust Metallurgical Results at Alamos Silver Project:
Recovers up to 94% Silver and 96% Gold
Minaurum Gold Inc. (“Minaurum” or “Company”) (TSXV: MGG) (OTCQX:MMRGF) is pleased
to report positive preliminary metallurgical testing results from composites of core samples taken
at the Promontorio and Europa targets at its 100% owned, fully production-permitted Alamos
Silver Project (“Alamos”) 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% to 94.3% for 5 of the 6 core composites
• Gold recoveries ranged from 68.9% to 96.5% in 5 composites with detectable gold
• Two separate independent labs conducted the tests
“These metallurgical results from sulfide-bearing mineralization show excellent silver and
gold recoveries and represent another de-risking milestone at the Alamos silver project ,”
stated Darrell Rader, President and CEO 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 composites 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 3 from core samples at the Europa vein zone and 3
from core samples at the Promontorio vein zone. For each vein zone, the 3 composites were
comprised of 1/4 cores corresponding from sample intervals with silver assays in ranges 150-250
g/t silver (low grade), 250-450 g/t silver (medium grade), and >450 g/t silver (high grade).
The Tecnológico de Metalurgia lab received low - and high-grade composites from Promontorio
and a medium-grade composite from Europa, while the Servicio Geológico Mexicano (SGM) lab
received low - 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 Pro montorio mine. Copper,
lead, and zinc recoveries were more variable . Results of the labs’ tests are summarized in Table
1.
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.

Mr. Benjamin Clingan, a metallurgist with more than 40 years’ 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, Tecnológico de Metalurgía of Hermosillo, and the testing lab of the Servicio
Geológico Mexicano - Mexican Geological Survey in Chihuahua.
