Lady Herial Mineral Resource Update
- Lady Herial Mineral Resource estimation now 0.56 million tonnes @ 2.0 g/t Au for 36,300 ounces
- Includes 0.23 million tonnes @ 2.6 g/t Au for 19,200 ounces in Measured Resource category
- Update follows extensive, close spaced drilling campaigns
Lunnon Metals Limited (ASX: LM8) is pleased to report an update to the Mineral Resource estimation (MRE) for its Lady Herial gold deposit, the Company's first gold discovery at its Kambalda Gold & Nickel Project (KGNP). The updated MRE as at 18 November 2025 at a 0.5 g/t Au cut-off grade is 0.56 million tonnes @ 2.0 g/t Au for 36,300 ounces, including a Measured Resource of 0.23 million tonnes @ 2.6 g/t Au for 19,200 ounces. The update follows extensive, close spaced drilling campaigns, with 400 holes (reverse circulation and diamond drill) totalling almost 17km of drilling informing the MRE. The MRE has been the subject of a Whittle open pit optimisation exercise, with the resultant potential pit shell capturing 92% (on a gold ounce basis) of the Measured Resource category material, providing great confidence in the future mining of Lady Herial. The Measured Resource has increased by material being reclassified from the Indicated Resource category, a direct benefit of the close spaced drilling. The overall average grade of the MRE has also increased, a result of the close spaced drilling improving the definition of both higher and lower grade zones. Regulatory approvals, which were submitted early in the September 2025 quarter, are expected in the near future, and once approved, the development footprint will be cleared and site pre-development activities will commence.
The June 2025 Lady Herial Scoping Study detailed the potential positive economic impact that Lady Herial might offer. The Company is well advanced with the regulatory approval process to mine the deposit as currently defined, with Whittle open pit optimisations followed by detailed studies demonstrating that Lady Herial has robust economics satisfying the Reasonable Prospects of Eventual Economic Extraction (RPEEE) assessment.
