    Capitan Silver’s Cruz de Plata: resource update and pit shell notes for mine planners

    Capitan Silver’s Cruz de Plata: resource update and pit shell notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Capitan Silver’s Cruz de Plata project in Durango has increased inferred contained metal at the Capitan Hill deposit to 39.8 million tonnes grading 0.41 g/t gold (525,000 oz) and 3.3 g/t silver (4.2 million oz), a 72% gold and 129% silver gain over the 2020 resource. The pit-constrained update uses a 0.18 g/t gold cut-off and a C$3,465/oz gold price, based on 12,209 metres of RC drilling in 49 holes. An expanded 15,000‑metre RC programme, two-thirds complete, is now targeting down-dip extensions of the Jesus Maria silver trend and other high-grade zones.

    Technical Brief

    • Pit-constrained resource uses a 0.18 g/t gold cut-off and C$3,465/oz gold price assumption.
    • Update covers only Capitan Hill, which occupies ~1% of the total Cruz de Plata area.
    • Inferred ounces increase >120% relative to the 2020 maiden resource for the same deposit area.
    • Resource estimate relies on 12,209 m of RC drilling from 49 holes completed in 2020–2021.
    • Current 15,000 m RC programme is ~two-thirds complete, with drilling scheduled to 20 December 2025.
    • A further 6–7 RC holes are planned pre-holiday, targeting down-dip Jesus Maria silver trend extensions.
    • Capitan Silver’s market capitalisation sits at ~C$282.1 million, with shares trading C$0.22–C$2.48 over 12 months.

    Our Take

    With Cruz de Plata’s Capitan Hill representing only about 1% of the project area yet already hosting 39.8 Mt of inferred material, the update suggests substantial upside if similar low-grade, bulk-tonnage mineralisation is confirmed along the wider Jesus Maria silver trend.

    The pit-constrained cut-off of 0.18 g/t gold and grades of 0.41 g/t Au and 3.3 g/t Ag place Cruz de Plata firmly in the low-grade, large-tonnage camp; in our database, such systems in Durango typically rely on scale, low strip ratios and heap leach or bulk milling to be competitive against higher-grade underground silver projects like La Parrilla.

    Capitan Silver’s C$282.1 million valuation and share price trading near its 12‑month high signal that the market is already pricing in exploration success; for practitioners, this often tightens the window for accretive JV or royalty deals compared with earlier-stage Mexican gold–silver stories in our coverage.

    EnergyX enters nuclear materials market: isotopes, Smackover project lens for mine planners

    Energy Exploration Technologies (EnergyX) has launched its NUKE-it platform to produce nuclear-grade lithium isotopes, targeting 15% enriched Lithium-6 for tokamak fusion and 99.999% pure Lithium-7 for thorium molten salt fission reactors. Building on its GET-Lit DLE extraction and refining suite, the company is tying isotope production to its Lonestar Lithium project in the Smackover formation, where it now controls 47,500 acres of lithium-rich brine after a US$26 million land deal. Uranium and thorium materials from upper Smackover limestone reservoirs in Arkansas and Louisiana are planned as follow-on products.

    America can’t defend itself with Chinese minerals: offshore supply lens for mine planners

    America’s near-total reliance on China for critical minerals – including 90% of global rare earth magnets, all ultrapure dysprosium and samarium for defence uses – is framed by NOIA president Erik Milito as a direct national security risk. Milito backs President Trump’s “Unleashing America’s Offshore Critical Minerals and Resources” executive order to fast-track offshore exploration, arguing that polymetallic nodules and shallow-water deposits could supply nickel, cobalt, manganese and copper at multi-generational scale. He points to decades of US sediment dredging and modern offshore robotics, monitoring and containment as evidence that well-regulated seabed mining can be run with controlled environmental impacts.

    Hancock–Maaden Saudi JV: exploration and project delivery lens for mine planners

    Hancock Prospecting and Saudi state miner Maaden have formed a joint venture to run exploration, development, mining, sales and marketing across licensed areas in Saudi Arabia, including five new exploration licences in the Nabita Ad-Duwayhi Gold-Belt. The partnership, announced alongside Round 9 licence awards at the Future Minerals Forum in Riyadh on 14 January, aims to accelerate discovery and project delivery under the Kingdom’s Vision 2030 pro-mining framework. Hancock brings large-project experience from Australia’s A$10 billion Roy iron ore project, while Maaden targets rapid build-out of a regional mineral hub and local talent pipeline.
