Minaurum Silver Inc. explores and develops precious- and base-metal projects in the Americas, with a concentration on its 100%-owned, production-permitted Alamos Silver Project in southern Sonora, Mexico, and the Lone Mountain CRD Project in Nevada. News about MMRGF centers on Alamos drilling, high-grade silver intercepts, vein-zone work at areas such as Europa, Promontorio-Travesia, Quintera, and San Jose, and technical reporting tied to mineral resource estimates.
Company updates also cover capital-structure matters, including private placements and warrants, as well as corporate actions such as the completed name change from Minaurum Gold Inc. to Minaurum Silver Inc.
Minaurum Silver (MMRGF) discovered the previously unrecognized Africa vein at its Alamos Silver Project in Sonora, Mexico, through resource-expansion drilling. Hole AL26-268 returned 669 grams per tonne silver equivalent (AgEq) over 2.05 metres, with an interpreted true width of 1.75 metres. Silver equivalent combines the metals into a silver-based grade using price and recovery assumptions. Africa lies about 50 metres west of Europa Sur and remains open along strike.
The ongoing 50,000-metre Phase II program also returned 367 g/t AgEq over 2.65 metres at Europa Sur and 253 g/t AgEq over 3.20 metres at Quintera, including 462 g/t AgEq over 1.50 metres. Promontorio Sur returned 691 g/t AgEq over 0.40 metres, while San Jose returned 782 g/t AgEq over 0.30 metres. Minaurum expects portions of Quintera and the San Jose zone to contribute to its updated resource estimate.
Minaurum Silver (MMRGF) reported drill assays from four vein zones at its Alamos Silver Project in Mexico on September 24, 2026.
At Europa Sur, hole AL26-246 returned 3.40 metres grading 397 grams per tonne silver equivalent (g/t AgEq), including 0.30 metre at 1,433 g/t AgEq. At San Jose, hole AL26-249 returned 0.90 metre at 1,469 g/t AgEq, including 0.50 metre at 2,425 g/t AgEq. Quintera yielded 0.50 metre at 1,559 g/t AgEq, while a Travesia intercept returned 1.90 metres at 323 g/t AgEq.
The first step-out results at Promontorio Sur included 0.45 metre at 386 g/t AgEq in a hole about 200 metres south of a fault separating it from Promontorio. The assays form part of Minaurum's ongoing 50,000-metre Phase II resource-expansion drilling program. Drilling continues at Promontorio Sur, with further assays pending.
Minaurum Silver (MMRGF) reports progress in underground rehabilitation and exploration at the historic Promontorio mine within its 100%-owned Alamos silver project in Sonora, Mexico. Safe access has now been established to more than 600 m of the main haulage level and a 55 m-deep internal Balvanera shaft, enabling detailed mapping and sampling.
Underground channel samples along the edges of historical stopes returned high grades, including 0.30 m grading 4,142 g/t silver equivalent (AgEq) and 0.50 m grading 733 g/t AgEq. Promontorio’s vein zone contributes 28.6 Moz AgEq of the project’s 55.2 Moz AgEq inaugural inferred resource from the Europa, Promontorio and Travesia vein zones. LIDAR surveys of accessible workings have been integrated into the project’s topographic and drill database to refine the geological model. Further rehabilitation is planned at the Quintera mine and at Minas Nuevas, Cotera and Pulpito vein zones.
Minaurum Silver (MMRGF) appointed Mr. Fernando Robles Noriega as Operations Manager of its production‑permitted Alamos Silver Project in Sonora, Mexico, and named veteran mining engineer Mr. Nicolas Figueroa Tapia to its Advisory Board.
Mr. Robles has 22 years of Mexican underground mining experience, including roles as Mine Superintendent at SilverCrest Metals’ Las Chispas operation, which was later acquired by Coeur Mining for $1.7 billion, and Underground Mine Manager at First Majestic’s San Dimas and Santa Elena mines. He will work with Minaurum’s exploration team on mine planning, potential production centers, underground mining methods, and future construction and infrastructure needs.
Mr. Figueroa brings 51 years of mining experience, including 40 years in senior operations with Industrias Peñoles, and will advise Robles and the operational team as Alamos mine development planning advances.
In connection with these appointments, Minaurum granted 385,000 stock options exercisable at $0.40 for 5 years, with 110,000 vesting immediately and about 275,000 vesting in four equal quarterly installments. The company also made a first grant of 1,315,000 Restricted Share Units to senior and key Mexican management, which will fully vest two years from grant and can settle in shares or cash at the company’s discretion.
Minaurum Silver (OTCQX: MMRGF, TSXV: MGG) reported new Phase II drill results from the Alamos silver project in Sonora, Mexico, highlighting high-grade intercepts at the Quintera, Europa Sur and San Jose vein zones within its 50,000-metre resource-expansion program.
At the Quintera vein zone, hole AL26-230 cut 26.30 m of 369 g/t AgEq, including 0.30 m of 2,418 g/t AgEq, and wedge hole AL26-230D returned 9.35 m of 162 g/t AgEq. Hole AL26-223 intersected 2.55 m of 185 g/t AgEq at greater depth.
In the Europa Sur extension, hole AL26-224 returned 3.40 m of 589 g/t AgEq, with sub-intervals up to 1,185 g/t AgEq, while hole AL26-225 delivered multiple narrow high-grade intervals, including 0.45 m of 2,069 g/t AgEq. The Europa vein hosts an inferred initial resource of 26.5 Moz AgEq out of 55.2 Moz AgEq at Alamos, excluding the Europa Sur extension.
At San Jose, hole AL26-220 intersected 4.75 m of 81 g/t AgEq. Minaurum stated that these results refine geological understanding and support ongoing resource-growth targeting.
Minaurum Silver (OTCQX: MMRGF) announced two initiatives to advance geological understanding of its 100%-owned, production-permitted Alamos Silver Project in Sonora, Mexico. The company has engaged Dr. Paula Montoya, an economic geologist and CODES Research Fellow, to complete a comprehensive district-scale geological study.
Minaurum also contracted PROINFRA Sistemas e Ingeniería to run gyroscopically oriented down-hole optical televiewer surveys on about 20 drill holes totaling 7,000 metres, focused on the Europa, La Quintera and Travesia vein zones, aiming to refine 3D models, improve drill targeting and support resource expansion.
Minaurum Silver (TSXV: MGG, OTCQX: MMRGF) has engaged SGS Metallurgy and Consulting Geological Services to complete an updated mineral resource estimate for its 100%-owned, high-grade Alamos Silver Project in Sonora, Mexico.
Minaurum’s inaugural January 2026 estimate outlined 5.37 million tonnes containing 55.2 million oz silver equivalent (AgEq), grading 320 g/t AgEq (202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead, 2.01% zinc). The NI 43-101 report, filed February 27, 2026, incorporated 104 drill holes totaling 35,888.15 m and 10,194 samples.
The company is executing a 50,000-metre, six-rig core-drilling campaign started in December 2025, targeting the Europa, Promontorio, Travesia, Promontorio Sur, Europa Sur, Quintera and San Jose vein zones. The forthcoming resource update will include new data from these areas and is expected later in 2026.
Minaurum Silver (OTCQX: MMRGF) reported new Phase II drill results from the Alamos silver project in Sonora, Mexico.
Highlights include 5.95 m of 1,117 g/t AgEq at Quintera, 3.65 m of 888 g/t AgEq at Europa Sur, and 8.5 m of 111 g/t AgEq at San Jose.
The Europa vein hosts an inferred resource of 26.5 Moz AgEq within a combined Europa-Promontorio-Travesia inferred resource of 55.2 Moz AgEq. Minaurum indicates these results support ongoing resource-expansion targeting multiple high-grade, stacked veins.
