    Newcore’s Enchi gold hits in Ghana: mine plan and grade uplift notes for engineers

    Newcore’s Enchi gold hits in Ghana: mine plan and grade uplift notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Newcore Gold has reported one of its widest, highest-grade intercepts at the Boin deposit on the Enchi project in Ghana, with reverse-circulation hole KBRC411 cutting 69 m at 2.59 g/t Au from 58 m depth, including 24 m at 6.41 g/t from 59 m, and KBRC414 returning 32 m at 0.83 g/t from 70 m, including 6 m at 3.37 g/t. The seven new RC holes, totalling 960 m over 1.9 km of strike and drilled to a maximum vertical depth of 125 m, all intersected mineralisation and target conversion of Boin’s 15.9 Mt probable reserve at 0.84 g/t and 23.5 Mt indicated at 0.73 g/t. These results, largely outside the June PFS resource that underpins a planned 5.5 Mt/y open-pit and mill producing 953,000 oz over 9.3 years, point to scope for higher-grade feed and mine plan optimisation as Newcore advances an 80,000 m programme and prepares a mining lease application.

    Technical Brief

    • Reported intercepts are downhole lengths, with true widths estimated at 75–85% of drilled thickness.
    • Boin’s gold-in-soil anomaly extends over 6 km, with ~40% of this strike still untested.
    • Average vertical drill depth at Boin is only ~100 m, indicating substantial room for down-dip extensions.
    • Newcore’s 80,000 m programme has completed 47,100 m to date, feeding future resource and reserve updates.
    • Reverse-circulation drilling is targeting near-surface resource conversion, while diamond drilling focuses on deeper, higher-grade Nyam-style targets.
    • At Nyam, diamond hole NBDD088 intersected 25.3 m at 3.67 g/t from 307.7 m, below the current pit shell.
    • Enchi’s June PFS envisages a 5.5 Mt/y open-pit and conventional mill, producing 953,000 oz over 9.3 years.
    • PFS economics at US$3,800/oz gold indicate US$496 million after-tax NPV5, 37% IRR and 1.6-year payback.
    • Initial construction capital for Enchi is estimated at US$351 million, for a multi-pit, central-plant configuration.
    • Enchi’s total probable reserve stands at 51.3 Mt at 0.64 g/t (1.06 Moz), with 83.6 Mt indicated and 40.1 Mt inferred.

    Our Take

    Across recent Ghana gold coverage, including Enchi and Asante Gold items, operators are increasingly highlighting below-pit mineralisation similar to Nyam’s 25.3m at 3.67 g/t, signalling that long-life, lower-grade open pits are being paired with higher-grade underground options to defend project NPVs against rising capex.

    With Enchi’s planned 5.5Mt/y throughput and a relatively modest C$107 million market valuation, the project sits in the smaller-cap, buildable end of African gold projects in our coverage, which can make it a more realistic takeover or JV target for mid-tier producers looking for pipeline ounces in Ghana.

    Canada refining more metals: value-chain design notes for mine planners

    Canada could add up to C$98 billion a year to GDP by 2035 if it shifts from exporting raw critical minerals to more complex products, Export Development Canada says, citing rare earths, graphite, lithium, copper and uranium as priority value chains. The report points to moving beyond ore into nuclear fuel and reactor components for uranium, and into specialty conductors, transformer components and AI‑grade power grid equipment for copper, building on assets such as Glencore’s Horne copper smelter. Key constraints are long-term risk capital, skilled labour, commercialisation capacity and trade infrastructure still geared to bulk exports.

    West Africa key to gold growth: project risk and power supply notes for engineers

    West Africa’s collective gold output now exceeds China’s, and Fortuna Mining CEO Jorge Ganoza says the region’s mineral endowment and rapid permitting and development timelines make it central to any growth strategy in precious metals despite higher geopolitical risk. Fortuna, which runs two mines in West Africa and two in Latin America, is tactically shifting capital between jurisdictions and has already started ordering critical power generators and other equipment for its newly acquired Bambadji project before securing an exploitation permit. Ganoza notes that competition from global data centres is constraining generator supply, limiting miners’ ability to secure units even with higher bids.

    Almonty–Wolfram Los Santos tailings deal: key process notes for mine engineers

    Almonty Industries has signed a long-term tungsten concentrate supply agreement with Sandvik subsidiary Wolfram Bergbau und Hütten AG for retreatment of the existing tailings stockpile at the Los Santos Mine in western Spain. The contract covers a minimum of about 1,720 t of contained WO₃ recovered from historical tailings, shifting the operation from primary ore mining to secondary extraction. For process engineers and tailings specialists, the deal signals continued commercial appetite for reprocessing fine-grained tungsten residues where grades and volumes justify dedicated retreatment circuits.
