Company Description
Minaurum Silver Inc. (trading in the U.S. over-the-counter market under the symbol MMRGF and on the TSX Venture Exchange as MGG) is an Americas-focused mineral exploration company. According to the company’s disclosures, it concentrates on the high-grade, 100% owned, production-permitted Alamos Silver Project in southern Sonora, Mexico and also holds interests in additional precious and base metal projects in the Americas.
The company announced that it changed its name from Minaurum Gold Inc. to Minaurum Silver Inc., highlighting its evolution into a silver-focused explorer and its emphasis on advancing and developing the flagship Alamos Silver Project in Sonora, Mexico. The board of directors approved the name change, and the company stated that its stock symbols remain MGG on the TSX Venture Exchange and MMRGF on the OTCQX.
Exploration focus and key projects
Minaurum describes itself as an Americas-focused explorer concentrating on high-grade silver projects. Its primary focus is the 100% owned, production-permitted Alamos Silver Project in southern Sonora, Mexico. Company news releases state that Alamos hosts multiple high-grade silver vein zones, including Promontorio, Europa, Travesia, Promontorio Sur, Quintera, Minas Nuevas, San Jose, Pulpito, and Cotera. The company reports that it has identified 26 vein zones in an 11 km by 6 km region covering part of the Alamos Project area, with a subset of these zones drilled and returning high-grade silver intercepts.
In addition to Alamos, Minaurum reports that it is advancing the Lone Mountain CRD Project in Nevada, USA. The company also refers to a portfolio of district-scale projects in Mexico and has disclosed a royalty interest in the Adelita Project in the Sonora-Arizona Copper Belt, where it exchanged a project interest for a net smelter return royalty on minerals extracted from Adelita.
Drilling and resource-definition work at Alamos
Company news releases describe extensive drilling activity at the Alamos Silver Project. Minaurum reports completion of a Phase I infill maiden resource drill program of approximately 10,000 meters targeting the Promontorio, Europa, and Travesia vein zones, with drilling returning numerous high-grade silver-equivalent intersections. The company states that these results will form the basis of an inaugural resource estimate at Alamos.
Following Phase I, Minaurum announced the commencement of a Phase II resource expansion drill program at Alamos. Initially planned at approximately 25,000 meters, the company later reported plans to expand Phase II to 50,000 meters, subject to financing. According to its disclosures, Phase II drilling is designed to test and expand existing targets and additional zones, including step-out holes at the Europa and Travesia silver shoots, further drilling at the historic Quintera and Minas Nuevas mines, and work on more recent discoveries at Promontorio Sur, Cotera, Pulpito, and San Jose vein zones.
Minaurum has also reported having multiple drill rigs on site at Alamos as part of its infill and resource-expansion programs, and notes that hundreds of drill pads have been permitted across the project. The company’s Qualified Person has described the quality assurance and quality control (QA/QC) procedures used for core sampling and assay analysis, including the use of standards, blanks, and duplicate samples, and the use of independent laboratories for sample preparation and analysis.
Promontorio, Europa, Travesia, and Promontorio Sur vein zones
Within Alamos, the company highlights several key vein systems. At the Promontorio vein zone, Minaurum reports a vein system approximately 1 km in length, consisting of multiple veins and associated skarn/carbonate replacement (CRD) mineralization hosted in limestone. Company drilling has intersected intervals of silver-equivalent mineralization that include silver, gold, copper, lead, and zinc values.
At the Europa vein zone, Minaurum describes a stacked vein system where drilling has extended mineralization down-dip and along strike. Reported intersections include multi-meter intervals of silver-equivalent mineralization with associated base metals. The company notes that Europa and Promontorio are among the high-priority targets intended to contribute to the maiden resource estimate at Alamos.
The Travesia vein zone is described as lying to the north of Promontorio in the same structural corridor. Company releases indicate that drilling at Travesia has intersected silver and base metal mineralization, and that further drilling is anticipated to test potential along strike and down dip.
Promontorio Sur is described as a 1.5 km-long vein zone representing the unmined southern continuation of the high-grade Promontorio stacked vein system. Minaurum states that Promontorio Sur is separated from Promontorio by a northwest-trending, steeply southwest-dipping fault and that drilling has intersected mineralization interpreted as representing high levels of the epithermal system, with potential for high-grade mineralization at depth. The company also reports CRD-style mineralization in altered limestone at Promontorio Sur.
Corporate evolution and technical team
Minaurum attributes its shift to a silver-focused identity to the development of the Alamos Silver Project and the experience of its technical team. The company notes that its founder, Dr. Peter Megaw, is credited with the discovery of the Juanicipio mine operated by MAG Silver Corp. Minaurum further reports that it has strengthened its technical leadership by adding resource modeling professionals who previously worked on SilverCrest Metals’ Las Chispas silver-gold deposit.
The company has announced the appointment of a Senior Project Manager for Alamos, along with additional geologists who collectively bring decades of exploration and resource evaluation experience in Mexican silver projects. Minaurum describes itself as being managed by a strong technical and finance team and indicates that it aims to continue its founders’ legacy by acquiring and developing a pipeline of Tier-One precious and base metal projects.
Financing and capital markets activity
Minaurum has disclosed capital raising activities to support its exploration programs. In one news release, the company announced the closing of a brokered private placement of units, with each unit consisting of a common share and a fraction of a common share purchase warrant. The company stated that it intends to use the net proceeds for exploration expenditures and completion of a Phase II drill program at the Alamos Silver Project, for property-related expenditures, and for general working capital, as described in its offering document.
The company has also reported entering into and renewing marketing and communications agreements with external firms to provide services such as social media consultation, social sentiment reporting, corporate video dissemination, and promotion of company activities through email distribution lists, websites, and blog posts.
Geographic footprint
Based on its public statements, Minaurum’s primary exploration activities are located in southern Sonora, Mexico, where the Alamos Silver Project is situated. The company also refers to a portfolio of district-scale projects in Mexico and to the Lone Mountain CRD Project in Nevada, USA. In addition, it holds a royalty interest in the Adelita Project in the Sonora-Arizona Copper Belt, where historical and more recent drilling has returned copper, gold, and silver intercepts.

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.
