G11 Resources Unveils Maiden Wilandra Copper Exploration Target Up to 21.2Mt

G11 Resources has announced a maiden Exploration Target for its Wilandra Copper Project, estimating a potential 15.6 to 21.2 million tonnes of copper mineralisation grading between 0.8% and 1.6% copper. The target spans three key zones over a 4 km strike length and remains open for expansion.

  • Maiden Exploration Target estimated for Wilandra Copper Project
  • Potential mineralisation of 15.6–21.2 million tonnes at 0.8–1.6% copper
  • Target covers Peveril, Central Gossan, and Grasmere zones over 4 km strike
  • Mineralisation remains open at depth and along strike
  • Further geophysical surveys and drilling planned to test and expand target

Exploration Target Announcement

G11 Resources Limited has released a significant update on its Wilandra Copper Project in New South Wales, unveiling a maiden Exploration Target that underscores the project's promising scale and grade potential. The estimate covers the Peveril, Central Gossan, and Grasmere zones, collectively stretching over a 4-kilometre strike length of copper mineralisation.

The Exploration Target is conceptual, with tonnage estimated between 15.6 and 21.2 million tonnes grading from 0.8% to 1.6% copper. This translates to an in-situ copper content ranging from approximately 170,000 to 250,000 tonnes. While the estimate is not yet classified as a Mineral Resource due to insufficient exploration, it highlights the potential size of the copper system.

Geological Context and Mineralisation Style

The Wilandra Copper Project lies within the underexplored Koonenberry Belt, a geologically complex region marked by multiple deformation events and a mix of sedimentary and volcanic rocks. The copper mineralisation is interpreted as a combination of volcanogenic massive sulphides (VMS) and structurally controlled massive sulphides, hosted primarily within the Grasmere Formation of the Cambrian Ponto Group.

The mineralised zones form a northwest-trending corridor up to 4.5 metres thick and extending 500 metres down dip. The mineralisation is open both at depth and along strike, suggesting further upside potential. Historical mining in the area produced high-grade copper, and recent drilling and geophysical surveys have refined the understanding of the deposit's continuity and extent.

Data Quality and Exploration Methodology

The Exploration Target was estimated by Conarco Consulting using a robust dataset comprising over 200 drillholes, including reverse circulation and diamond core drilling. Despite some challenges with drillhole deviation affecting spatial accuracy, the data quality and sampling techniques meet industry standards. Bulk density measurements and geophysical surveys, including downhole electromagnetic methods, support the continuity and potential scale of the mineralisation.

G11 Resources has applied conservative criteria in defining mineralised intervals, with a copper cutoff grade of 0.25% and minimum widths to ensure realistic tonnage estimates. The company plans to conduct further ground-based geophysical surveys and follow-up drilling to test for copper-rich VMS mineralisation and structurally remobilised sulphides.

Outlook and Market Implications

Executive Chairman Martin Donohue expressed optimism about the maiden Exploration Target, emphasizing the underexplored nature of the Wilandra area and the potential to expand the mineralised system. The announcement positions G11 Resources as a copper explorer with a sizeable target in a prospective geological setting, which could attract further investor interest as exploration advances.

However, the conceptual nature of the target means that significant work remains to convert it into a defined Mineral Resource. The upcoming exploration programs will be critical in validating the size and grade potential and in reducing geological uncertainties.

Bottom Line?

G11 Resources’ Wilandra maiden Exploration Target sets the stage for a pivotal exploration phase that could redefine the project’s copper potential.

Questions in the middle?

  • How will upcoming drilling programs refine the Exploration Target and potentially define a Mineral Resource?
  • What are the risks associated with drillhole deviation and data accuracy in estimating the mineralisation?
  • Could the Wilandra Copper Project’s mineralisation extend beyond the currently defined 4 km strike length?
