    Endurance Gold Reliance step-outs: resource and metallurgy lens for mine planners

    Endurance Gold Reliance step-outs: resource and metallurgy lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Endurance Gold’s 2026 drilling at the Reliance project in southern British Columbia has returned high-grade step-outs outside the current resource, including 14.7 metres at 7.67 g/t gold and 0.13% antimony from 75.9 metres in DDH26-128 and 12 metres at 3.07 g/t gold from 98.2 metres in DDH26-129, a 60-metre step-out along the Eagle trend. The 8,000-metre diamond programme, with seven holes (1,899 metres) already completed at southern Eagle and two deep tests at Imperial, targets conversion of near-surface ounces and deeper Royal Shear extensions. Reliance currently hosts 19.6 million inferred tonnes at 2.3 g/t gold (1.45 million oz), with metallurgical work aiming to improve recoveries beyond earlier 84.7% gold to concentrate.

    Technical Brief

    • DDH26-128 intersected five additional lower veins between 118.1–161.0 m, 0.5–1.6 m wide grading 2.57–10.10 g/t Au.
    • The same hole cut Eagle mineralisation 25 m closer to surface than 2022 hole DDH22-027.
    • DDH26-129, drilled from the same pad at a different azimuth, confirmed Royal Shear-hosted mineralisation continuity.
    • True widths for reported Eagle intercepts are estimated at 80–100% of core length, limiting dilution uncertainty.
    • Seven diamond holes totalling 1,899 m at southern Eagle all show visible mineralisation in previously undrilled ground.
    • Those seven Eagle holes intersected 11 mineralised structures ranging from 2.1–10.5 m in core length; assays pending.
    • At Imperial, two deep holes (1,160 m total) stepped 43 m and 55 m off prior Royal Shear intercepts.
    • Historical Imperial hole DDH24-109 returned 21.8 m at 6.74 g/t Au, including 12.4 m at 10.11 g/t Au, guiding current depth tests.
    • Metallurgical testwork is focused on upgrading gold and antimony recoveries beyond the earlier 84.7% Au to concentrate.
    • A reverse-circulation rig is planned to test the Eagle Offset anomaly, enabling cheaper, faster near-surface targeting.

    Our Take

    With 1.45 million oz inferred at 2.3 g/t and a current market capitalisation of about C$85 million, Endurance Gold is trading at a relatively low in-situ value per ounce compared with several other Canadian gold developers in our database, so consistent step-out success at Eagle and Imperial could have an outsized impact on valuation.

    The pit-constrained component at Reliance (1.12 million oz at 2.23 g/t) and prior 84.7% recovery to a marketable concentrate suggest the project is already screening as a potentially competitive open-pittable gold asset in southern British Columbia, where permitting risk has become more visible following disputes such as the MCC Canadian Gold Ventures case filed against the province in 2024.

    Codelco’s ongoing 3–4 month investment review around Reliance introduces a strategic angle unusual among the gold-focused ‘Projects’ stories in our coverage, as the Chilean copper major’s involvement could de-risk future funding and signal interest in gold–antimony systems alongside its core copper portfolio.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
