    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.

    Sasquatch Resources’ Mount Sicker waste rock: design and risk notes for mine engineers

    Sasquatch Resources is targeting roughly 300,000 tonnes of sulphide-bearing waste rock at the historic Mount Sicker copper-gold district on Vancouver Island, where legacy piles with a neutralisation potential of 0.2 and open shafts up to 200 feet deep continue to generate acid runoff and physical hazards. Modern sampling of the surface waste has returned average grades of about 2 g/t gold plus copper, silver and zinc, and the company plans to crush and process the material using density and X-ray fluorescence (XRF) ore-sorting in a closed-loop, reagent-free circuit. Because the project involves large-scale reprocessing without new mining, Sasquatch is working with regulators to craft a bespoke permitting pathway that could be replicated across an estimated 2,000 legacy mine sites in British Columbia.

    Mining companies’ new technology roadmaps: ERP design lessons for project teams

    Mining companies are redrawing 2026 technology roadmaps around cloud ERP platforms such as SAP, shifting from legacy spreadsheets and siloed systems to a single financial and operational backbone spanning finance, capital management, procurement, supply chain and maintenance. Clean-core architectures with extensibility and open interfaces are being used to plug in geology asset management, environmental monitoring and safety applications without heavy customisation, cutting technical debt and easing upgrades. With harmonised master data and automated consolidations delivering near real-time views of cash, capex and asset performance, miners can support AI-driven predictive maintenance and tighter working-capital control across multi-jurisdictional portfolios.

    Echion XNO® battery launch with GUS: implications for mine electrification

    Echion has launched a commercial range of fast-charging, high‑power lithium‑ion batteries using its niobium‑based XNO® anode technology, produced in partnership with GUS Technology at GUS’s Zhongli manufacturing facility in Taiwan. The XNO® chemistry targets applications needing very high charge rates and power density, such as mining haul trucks, drills and underground fleets where current graphite‑anode packs struggle with rapid cycling and peak load demands. For mine electrification projects, the move signals growing availability of alternative anode chemistries that can better tolerate high C‑rates and harsh duty cycles.
