    Lunahuasi Jupiter assays: resource growth and drilling priorities for mine planners

    Lunahuasi Jupiter assays: resource growth and drilling priorities for mine planners

    First reported on MINING.com

    30 Second Briefing

    Copper-gold-silver assays from NGEx Minerals’ Lunahuasi project in northern Argentina have extended the high-grade Jupiter zone and expanded Saturn, with headline hole DPDH077 at Jupiter cutting 10 metres from 89 metres depth grading 0.88% copper, 3.14 g/t gold and 12.2 g/t silver, including 7.6 metres at 18.84% copper, 5.54 g/t gold and 336.7 g/t silver. Saturn results include DPDH069 with 135 metres at 1.18% copper, 0.81 g/t gold and 27.2 g/t silver from 437 metres, and DPDH072 with 34 metres at 1.43% copper, 1.8 g/t gold and 40.2 g/t silver from 193 metres, suggesting a large, structurally controlled disseminated and stockwork system with multiple very high-grade veins and a possible new zone east of Saturn. The stage 4 programme totals 27,318 metres across 32 holes, with Jupiter now a priority for stage 5 targeting a potentially larger future resource, while NGEx’s TSX shares eased 2% to $23.96, valuing the company at $5.2 billion.

    Technical Brief

    • Stage 4 drilling totals 27,318 metres across 32 holes at Lunahuasi.
    • Jupiter mineralisation is now confirmed over roughly 400 m x 500 m areal extent.
    • Lunahuasi lies about 1,300 km north-west of Buenos Aires in northern Argentina’s Andes.
    • Fewer holes have been completed at Jupiter than at the Saturn and Mars targets to date.
    • Saturn is interpreted as a structurally controlled disseminated and stockwork system cut by very high-grade veins.
    • Intersections in DPDH072 suggest an emerging, previously unrecognised mineralised zone east of the current Saturn footprint.
    • Ongoing drilling aims to physically connect discrete mineralised zones into a single, larger resource envelope.

    Our Take

    The copper-gold-silver tenor at Lunahuasi’s Jupiter and Saturn zones puts NGEx Minerals into the same high-grade narrative as other copper-gold names in our database, but unlike the Central Asia Metals–Cygnus or Kodiak–Teck transactions, NGEx is still in the pure exploration/de-risking phase rather than consolidation or M&A.

    The combination of very high-grade short intervals (e.g., sub-10 m runs) within broader mineralised envelopes at Lunahuasi echoes the grade distribution seen in several copper-gold porphyry and epithermal systems in our coverage, implying NGEx may ultimately have optionality between a bulk-underground approach and selective high-grade stoping if continuity is confirmed.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
