Lunnon Metals (ASX:LM8) unlocks high gold recoveries at Lady Herial
February 17, 2025Metallurgical test work may not typically grab headlines, but in the case of Lunnon Metals (ASX:LM8), its latest results at the Lady Herial prospect in Kambalda could prove pivotal.
The initial ‘sighter’ test work confirms what geologists have long suspected: this is free-milling gold with a significant gravity-recoverable component.
Translation? Minimal processing headaches and the potential for a near-term cash-generating open pit.
The 13-sample test program delivered an average gold recovery of 95%, with some samples reaching an eye-popping 99.3%—a figure that would turn heads even in Kalgoorlie’s Golden Mile.
Managing Director Edmund Ainscough sees this as a major de-risking step:
“These results are another significant de-risking step completed at Lady Herial. The next step is to complete further test work which will be aligned with the process flow for the gold plant that this material ultimately ends up at.”
Key Highlights:
- High recoveries across all material types: Free-milling gold is the holy grail of processing, and Lady Herial delivers.
- Low reagent consumption: This means lower operating costs and potential for fast-tracked production.
- Significant gravity recoverable component: 80.1% gravity recovery in one test suggests potential for further optimisation.
Lunnon Metals is no stranger to Kambalda’s geology, with its nickel pedigree well established.
But the company’s gold ambitions could become a game-changer, particularly in a high gold price environment.
The Lady Herial deposit sits within granted mining leases, adjacent to established processing infrastructure—an enviable position for any gold hopeful looking to monetise ounces quickly.
Ainscough describes Lady Herial as a “classic St Ives deposit”, a nod to its geological kinship with the world-class deposits that have made Kambalda a household name in mining circles.
With further test work planned, including the addition of a gravity circuit to the process flow, recoveries could climb even higher.
The Bigger Picture
Lady Herial is just one part of Lunnon’s broader gold strategy.
The 2025 program includes infill drilling, mineral resource estimation, and preliminary pit optimisation studies.
The company is also in discussions with third parties—including Gold Fields—on potential ore purchase or toll treatment deals.
Lunnon is also chasing larger-scale discoveries, targeting multiple gold prospects across its Kambalda tenure.
With a disciplined exploration strategy and a team with deep regional experience, the company is positioning itself as a serious player in Kambalda’s evolving gold narrative.
The Market’s Take
Investors have seen plenty of junior gold hopefuls over the years, but Lunnon brings something different: a high-grade asset with low-cost processing potential, situated in a tier-one jurisdiction with existing infrastructure.
For those looking beyond the usual exploration story, Lady Herial’s test results provide a compelling reason to watch this space.
