Golden Grove mine life uplift: drilling takeaways for planners and engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
High-grade copper and zinc intercepts from recent drilling at 29Metals’ Golden Grove mine in Western Australia are boosting confidence in extending mine life and upgrading resources. Step-out and infill holes around the Gossan Hill and Scuddles lenses have returned multiple thick sulphide zones, including massive and stringer mineralisation with grades reported as well above current reserve averages. The results support further underground development targeting deeper extensions of the volcanic-hosted massive sulphide system, with planning now focused on converting inferred tonnes and optimising sequencing of copper- versus zinc-dominant stopes.
Technical Brief
- Golden Grove is an underground volcanic-hosted massive sulphide operation in Western Australia owned by 29Metals.
- Ore is currently mined from the Gossan Hill and Scuddles deposits, both accessed via established underground infrastructure.
- The mine produces copper, zinc, lead, silver and gold concentrates through an on-site processing plant.
- Processing uses conventional crushing, grinding and flotation circuits to generate separate copper and zinc concentrates.
- Existing underground development around Gossan Hill provides platforms for step-out and down-dip drilling of deeper lenses.
- Scuddles’ historical production and drilling density provide a strong dataset for resource modelling and stope design refinement.
- Any mine life extension will require updated underground scheduling to balance ore haulage, ventilation and backfill sequencing.
Our Take
Golden Grove’s copper and zinc profile sits within a crowded field in our database, with 184 keyword‑matched pieces on these metals, so incremental mine‑life extensions here are competing for capital and attention against a wide range of global base‑metal projects.
Among the 674 Mining stories and 1269 Projects‑tagged pieces in our coverage, Australian copper assets like Golden Grove tend to be viewed as lower jurisdictional risk than many Latin American or African peers, which can make even modest life extensions strategically valuable for offtakers and financiers.
With copper also central to the potential Rio Tinto–Glencore consolidation flagged in our 18 January 2026 coverage, longer‑dated copper output from Australian operations such as Golden Grove could become more important for smelters and traders looking to diversify away from production dominated by a few global majors.
