    Atlantic Lithium’s Ewoyaa mine approval: sliding royalties and offtake lens for engineers

    Atlantic Lithium’s Ewoyaa mine approval: sliding royalties and offtake lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Atlantic Lithium has secured Ghanaian parliamentary ratification of a 15‑year mining lease for the Ewoyaa lithium project, introducing a sliding royalty on spodumene concentrate from 5% below $1,500/t to 12% above $3,200/t in place of a flat 10%. The mine and processing plant are planned to deliver 3.6 Mt of concentrate over 12 years, with 50% of output already committed to Elevra Lithium, the merged Piedmont–Sayona entity. The approval unlocks project financing and positions Ewoyaa as Ghana’s first lithium operation and a US‑aligned alternative to Chinese‑backed African supply.

    Technical Brief

    • Sliding royalty mechanism ranges from 5% below $1,500/t to 12% above $3,200/t concentrate.
    • Ratified 15‑year mining lease removes key permitting risk and enables formal project financing processes.
    • Project delays were driven by post‑2022 lithium price retrace, forcing renegotiation of fiscal terms with government.
    • Ewoyaa is described by Atlantic as the third‑largest lithium project under development in Africa.
    • Offtake partner Elevra Lithium inherits prior Piedmont agreements supplying OEMs such as Tesla and LG Chem.
    • US policy under the Trump administration to de‑risk Chinese supply chains underpins strategic interest in Ewoyaa.

    Our Take

    The 5–12% sliding royalty on Ewoyaa, replacing the previously sought flat 10%, gives Ghana exposure to lithium price upside while still leaving room for margins at lower prices, which is likely to be a reference point for other African critical-mineral regimes in our database that are revisiting fiscal terms.

    Focus Graphite’s Lac Tetepisca resource: capex and pit geometry notes for engineers

    Focus Graphite’s Lac Tetepisca project in central Quebec now hosts 14.7 million tonnes of contained graphite at 10.2% Cg, an 86% increase over its 2022 resource, ranking fifth globally and second in North America by contained tonnes. The updated estimate, based on 26,095 metres of drilling in 150 holes, includes 12.3 million tonnes contained graphite in measured and indicated resources (120.1 million tonnes at 10.27% Cg) plus 2.3 million tonnes inferred (24.1 million tonnes at 9.88% Cg). Grades above 10% Cg, open-pit geometry with favourable strip ratios, low-cost Quebec hydropower and planned >99.9% purity processing underpin analyst views that Focus trades at an 81% discount to peers.

    Freeport’s delayed Grasberg restart to 2028: production and risk notes for mine engineers

    Freeport Indonesia has pushed back Grasberg’s full production restart to early 2028, after a September mudflow in the Grasberg Block Cave killed seven workers, halted underground mining and triggered force majeure on shipments. The complex, which previously supplied about 3% of global copper (1.7 billion lb/year) and 1.4 million oz/year of gold, is currently operating at roughly 40–50% capacity, with copper output for 2026 now guided at 700 million lb versus a prior 1‑billion‑lb target. Ramp-up targets have been reset to 65% capacity in H2 2026 and 80% by mid‑2027, as additional logistics and ore-handling infrastructure work proceeds.

    San Lorenzo Chile gold assays: porphyry potential and drilling cues for mine planners

    San Lorenzo Gold’s Salvadora project in Chile’s Atacama region returned strong gold intercepts at the Arco de Oro target, with hole SAL-10-25 cutting 102 m at 1.33 g/t Au from 153 m (including 13 m at 2.21 g/t), and nearby SAL-09-25 yielding 59 m at 1.07 g/t Au from 238 m (including 11 m at 3.78 g/t). Exploration VP Terence Walker interprets the results as the upper levels of a gold‑rich porphyry Cu‑Au system, open in all directions and warranting immediate follow‑up drilling. The 90+ sq. km Salvadora property lies about 15 km from Codelco’s El Salvador mine, and a C$20 million March placement is funding ongoing step‑out drilling across five porphyry and epithermal targets.
