    Minaurum Alamos silver resource in Mexico: key tonnage and grade notes for mine planners

    Minaurum Alamos silver resource in Mexico: key tonnage and grade notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Minaurum Silver has reported an inferred mineral resource at its 100%-owned Alamos project in Sonora of 5.37 million tonnes grading 202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead and 2.01% zinc, equivalent to 320 g/t AgEq and containing 55.2 million oz AgEq. The estimate, which incorporates smelter and processing deductions more typical of advanced studies, is based on 104 drillholes totalling 35,888 m and 10,194 samples across the Promontorio, Travesia and Europa veins. Mineralisation remains open along strike and at depth, with a 50,000 m Phase II drilling campaign under way to expand the resource beyond three of the 26 identified vein zones.

    Technical Brief

    • Contained metals total 34.8 Moz Ag, 35,640 oz Au, 51 Mlb Cu, 115 Mlb Pb, 238 Mlb Zn.
    • Silver-equivalent inventory is reported as 55.2 million ounces AgEq contained.
    • Smelter and processing deductions were explicitly applied, aligning inputs with assumptions typical of advanced economic studies.
    • Sensitivity analysis shows the resource remains robust at cut-off grades higher than 150 g/t AgEq.
    • Database comprises 104 drillholes totalling 35,888.15 m and 10,194 individual samples.
    • Current MRE only covers parts of Promontorio, Travesia and Europa, three of 26 mapped vein zones.
    • All three modelled vein zones are described as remaining open both along strike and down-dip.
    • Phase II drilling (50,000 m planned) is explicitly framed as a resource expansion programme rather than pure exploration.

    Our Take

    With inferred silver-equivalent of about 55 Moz at Alamos and spot silver recently trading near or above $100/oz in our recent price coverage, even a modest conversion of this resource to reserves could materially re-rate Minaurum Silver relative to single-asset juniors in Mexico.

    The polymetallic mix at Alamos (notably copper, lead and zinc alongside silver and gold) provides some hedge against the copper demand softness flagged in Goldman’s survey of a 10–30% decline in fabricator order books, as project economics will not be solely copper-price dependent.

    Among the 781 Mining stories in our database, relatively few Mexico and Central America ‘Projects’ pieces report 100% ownership of a multi-vein system like Alamos, which gives Minaurum Silver more flexibility on future financing structures and potential JV or streaming negotiations.

    Queensland 2025 Resources Awards for Women: workforce lessons for mine operators

    Queensland’s 2025 Resources Awards for Women have named 18 finalists spanning roles from engineering superintendent and diesel fitter to dragline operator and chief operating officer across coal, metals and quarrying operations. Nominees include frontline trades, site-based supervisors and corporate leaders from major producers and contractors, with categories covering technical excellence, safety leadership and gender diversity initiatives. For mine operators, the awards signal growing recognition of women in production-critical roles and may influence recruitment, apprenticeship intake and retention strategies on remote sites.

    Tungsten Mining’s $53m critical minerals raise: project pipeline signals for engineers

    Tungsten Mining has raised $53 million via a placement after being listed in the Australian Critical Minerals Prospectus, bolstering funding for its tungsten-focused project pipeline. The capital injection strengthens the company’s balance sheet for advancing drilling, resource definition and feasibility work on Australian tungsten deposits, a metal critical for hardmetals, drill bits and high-temperature alloys. For mining engineers and project developers, the raise signals continued investor appetite for domestic critical minerals projects despite limited public detail on specific mine capacities or development timelines.

    Victory’s hafnium at North Stanmore: flowsheet and revenue notes for engineers

    Victory Metals has reported metallurgical test work at its North Stanmore rare earths project near Cue in Western Australia confirming a high-value hafnium by-product alongside its clay-hosted REE mineralisation. The company is advancing flowsheet development to selectively recover hafnium from leach solutions already designed for rare earth extraction, positioning the metal as a potential “game-changer” revenue stream. For process and project engineers, the key issue will be integrating hafnium separation into existing hydrometallurgical circuits without materially increasing reagent consumption or capital intensity.
