CGN Resources (ASX:CGR) has unveiled age-dating sample results from its Webb Copper-Gold-Nickel Project in West Arunta, Western Australia.
CGN reveals its 2025 Kandula core drilling program returned ‘highly encouraging’ results.
Lithologies that intersect the project’s northern section are significantly older than previously interpreted. The company hopes this will materially enhance prospects for numerous high-quality targets at the soon-to-be-drilled Elmar and Kandula deposits.
The Timescales of Mineral Systems Group from Curtin University’s Curtin Frontier Institute for Geoscience Solutions (CFIGS) has been appointed for geochronology work at the site.
The latest data indicate that northern project rocks are comparable in age to the Lander Rock Formation, which hosts the nearby Luni and Green deposits, held by WA1 Resources (ASX:WA1) and Encounter Resources (ASX:ENR), respectively.
Namely, dolerite is dated at approximately 1563 mega annum (plus or minus 52 Ma), while sedimentary units are estimated at around 1828 Ma (plus or minus 14 Ma). This places them within a “highly prospective window for intrusive activity associated with the emplacement of the Luni and Green carbonatites”.
This revised geological interpretation significantly upgrades the company’s exploration model.
These results also reinforce the potential for carbonatite mineral systems, as well as iron oxide copper-gold style systems.
CGN has already secured heritage clearance across key target areas. The company now plans to advance systematic exploration programs.
“Age-dating has fundamentally reshaped our geological understanding of this highly underexplored part of the West Arunta … [and] it is particularly rewarding to see high-quality, systematic geoscience deliver new data that materially advances knowledge of the region, and opens new exploration opportunities,” Managing Director Stan Wholley says.
“Our immediate focus is to integrate these results into our evolving geological model and accelerate planned exploration activities at Elmer and Kandula … [and] this disciplined, science-led approach provides a strong foundation and growing confidence.”
CGN Resources is a copper, gold, nickel, and critical metals exploration company with assets mainly in Western Australia.
