Great Western Secures Option to Acquire McKinlay Copper-Gold-Silver Project with Aggressive Exploration Plans
Great Western Exploration (ASX:GTE) has entered a farm-in deal to earn up to 100% of the McKinlay Copper-Gold and Silver Project near Cloncurry, Queensland, targeting Ernest Henry-style IOCG and Cannington-style silver-lead deposits with a planned drilling campaign.
- Farm-in agreement to earn up to 100% in McKinlay project
- Targets include Ernest Henry-style IOCG and Cannington-style silver-lead
- Historical drilling shows significant copper, gold, and silver intercepts
- Exploration program to include air core, RC drilling, and geophysics
- Shareholder approval required due to related party interests
Strategic Entry into a Proven Mineral Province
Great Western Exploration (ASX:GTE) is making a significant move into Queensland’s prolific Mt Isa Eastern Succession with a farm-in agreement to earn up to 100% of the McKinlay Copper-Gold and Silver Project, located 80km southeast of Cloncurry. This region hosts some of Australia’s largest and longest-lived mines, including Ernest Henry, Eloise, Osborne, and the world-renowned Cannington silver-lead deposit.
The McKinlay Project’s allure lies in its geological setting, sharing the same stratigraphic units as these giants, and the presence of multiple Ernest Henry-style iron oxide copper gold (IOCG) and Cannington-style silver-lead targets. Notably, these deposits were historically discovered beneath shallow cover with no surface expression, detected instead via coincident gravity and magnetic geophysical anomalies.
Untapped Potential Backed by Historical Data
These targets exhibit strong geophysical signatures akin to Ernest Henry, with coincident magnetic and gravity highs. For example, the Deere target is interpreted as the southern margin of a large-scale IOCG system, with no drilling within a kilometre north of the significant intercept. Similarly, Ventura presents an electromagnetic and magnetic anomaly beneath shallow scree cover, untested by drilling.
Aggressive Exploration Program Planned
Great Western plans to launch an aggressive exploration campaign shortly after acquisition completion, pending shareholder approval. The program will include ground-based gravity surveys to refine targets, air core drilling at Ventura to test beneath shallow cover, and reverse circulation (RC) drilling at Stellantis and Dylans once permits are in place. These efforts aim to leverage modern exploration techniques, inspired by recent successes nearby such as AIC Mines’ Brumby Prospect, which lies just 26km southwest and has delivered significant copper and gold results.
The McKinlay acquisition complements Great Western’s existing portfolio, which includes the Juggernaut copper-gold targets in Western Australia’s Yerrida North Project, where drilling results are expected imminently. The company’s strong cash position of $3.4 million as of June 2026 supports these exploration ambitions.
Farm-In Terms and Governance Considerations
The farm-in with private company Moffat Resources Pty Ltd allows Great Western to earn an initial 51% interest by spending $500,000 on exploration within 12 months of shareholder approval. A further 29% interest can be earned by committing an additional $2 million over the following two years. Full ownership (100%) can be secured by paying up to $2 million in cash or shares, with Moffat retaining a 1% net smelter return royalty.
Moffat Resources is partly owned by Great Western’s Managing Director Shane Pike, who abstained from board discussions regarding the transaction. The independent directors consider the deal in shareholders’ best interests, but it requires non-associated shareholder approval under ASX Listing Rule 10.1 due to related party status. The general meeting is scheduled for late September 2026.
Tenure and Regulatory Risks
The project’s tenure is due to expire on 28 February 2027, triggering a compulsory 50% relinquishment of current tenement areas under Queensland law. Relinquished blocks enter a moratorium before potentially being reapplied for, but there is no guarantee Great Western or Moffat will retain these areas. This introduces uncertainty around the ultimate project footprint and the extent of mineralisation accessible under the earn-in.
Great Western retains the right to withdraw from the earn-in at any stage before completing full ownership, transferring any interest back to Moffat for a nominal sum.
Bottom Line?
Great Western’s entry into McKinlay offers exposure to a proven mineral province with underexplored targets, but tenure expiry and shareholder approval remain key hurdles to watch.
Questions in the middle?
- Will Great Western secure shareholder approval given the related party nature of the deal?
- How will the compulsory tenure relinquishment impact the scale and value of the McKinlay Project?
- Can modern exploration techniques unlock significant discoveries where previous drilling left targets under-tested?
