    Wildcat’s Bolt Cutter Central lithium discovery: pit design and resource notes for engineers

    Wildcat’s Bolt Cutter Central lithium discovery: pit design and resource notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Wildcat Resources has extended its Bolt Cutter Central lithium discovery in Western Australia, with new drilling indicating a larger mineralised system than initially defined. Recent reverse circulation and diamond holes have expanded the strike and depth continuity of spodumene-bearing pegmatites, suggesting potential to grow the existing resource footprint. For mine planners and geotechs, the results point to a more substantial open-pit or potential underground scenario, with further infill and step-out drilling likely to refine geometry, grade distribution and pit shell economics.

    Technical Brief

    • Reverse circulation and diamond drilling are being used to define pegmatite geometry and continuity.
    • New holes target both along-strike extensions and deeper structural positions beneath earlier intercepts.
    • Core drilling will allow oriented-structure logging to refine pegmatite dip, thickness and fault offsets.
    • Step-out drilling spacing is being widened to test system limits before committing to dense infill.
    • Geotechnical data from diamond core (RQD, fracture sets) will underpin preliminary pit slope assumptions.
    • RC chips and core are supporting detailed lithological logging to distinguish spodumene-rich from barren pegmatites.
    • Results will inform early-stage mine scheduling trade-offs between shallow bulk tonnage and deeper higher-grade zones.

    Our Take

    Wildcat Resources’ lithium exploration at Bolt Cutter Central sits in the same Western Australian supply narrative as Liontown’s Kathleen Valley offtake to Canmax, signalling that even early‑stage finds are being evaluated against future contract demand from converters and OEMs.

    Across the 24 lithium‑keyword pieces in our database, most Australian stories are already tied to defined offtakes or advanced studies, so a growing discovery‑stage position like Bolt Cutter Central could become a takeover or JV target if drilling confirms scale and grade.

    BMI’s outlook for firmer lithium prices in 2026, highlighted in our recent coverage, would improve the option value of greenfield Australian lithium projects such as Bolt Cutter Central, supporting more aggressive step‑out drilling and resource definition than would be justified in a weak price environment.

    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.
