Everest Metals has converted part of its Mt Dimer gold resource from Inferred into higher-confidence Measured and Indicated categories, while mining has produced a 142,000-tonne stockpile ahead of planned toll treatment. The immediate test is whether that stockpile can become cash flow, while deeper drilling seeks to expand confidence below the current pit.
- 975,000 tonnes at 1.37 g/t gold for 42,978 ounces
- Measured and Indicated resources now represent 32% of contained gold
- 142,000 tonnes stockpiled at 1.33 g/t for 6,072 ounces
- 7,244 metres of recent drilling supported the confidence upgrade
- Deeper mineralisation remains open and requires further drilling
Mt Dimer gains its first higher-confidence resource
Everest Metals Corporation Ltd (ASX:EMC) has upgraded the geological confidence of its Mt Dimer Taipan gold project, establishing Measured and Indicated Resources there for the first time. The updated JORC 2012 estimate totals 975,000 tonnes at 1.37 grams per tonne gold for 42,978 ounces, rounded by the company to 43,000 ounces, using a 0.5 g/t cut-off.
Measured and Indicated material accounts for 13,780 ounces, or 32% of the total. That is a meaningful change from the entirely Inferred estimate reported in 2021, although most of the current resource remains Inferred. The company says the upgrade reflects 7,244 metres of drilling completed between November 2025 and May 2026, combined with observations from open-pit mining.
Stockpile puts the processing test ahead
The most immediate operational asset is not buried below the pit. EMC has mined and stockpiled 142,000 tonnes grading 1.33 g/t gold for an estimated 6,072 ounces on the run-of-mine pad. The material is reported separately from the in-situ resource and is not itself a Mineral Resource classification category, despite being described in the announcement as an Indicated stockpile resource.
The stockpile has grown from the 92,788 tonnes previously reported at the company’s Mt Dimer mining milestone, and now represents the proposed feed for toll-processing campaigns. EMC says processing remains subject to scheduling, haulage logistics, facility availability and the commercial conditions of its arrangements with third-party operators. No production has yet occurred.
Toll treatment offers a route to revenue
Under its Right to Mine Agreement, MEGA Resources and Bain Global Resources provide development and working capital funding and manage mining, haulage and third-party processing. EMC describes the arrangement as non-dilutive. The processing pathway includes campaign-based arrangements involving Forrestania Resources facilities and a 200,000-tonne agreement with Medallion Metals (ASX:MM8) at its Cosmic Bay facility.
Metallurgical results provide support for the proposed approach, but they are not a substitute for a completed campaign. Recent testwork reported recoveries of 95% for oxide, 98% for fresh material and 93% for transitional material. The commercial question is now practical: when can the accumulated ore be hauled and processed, and what recovery and payable-gold outcomes will emerge?
Deeper drilling remains the resource wildcard
The current estimate is strongest in the upper part of the deposit, where drilling was tightened to approximately 12.5 metres along strike and six metres across strike. The company models the principal mineralised vein over roughly 720 metres of strike and to about 180 metres below surface, but confidence falls below approximately 100 metres as drill spacing widens.
Further drilling is planned beneath the current pit because mineralisation remains open at depth. The updated estimate also contains less reported gold than the 2021 estimate, while silver is no longer included because the available silver data is not considered sufficiently dense or spatially representative. That leaves two separate measures of progress: near-term validation through toll processing, and longer-term validation through conversion of deeper Inferred material.
Bottom Line?
The resource upgrade improves confidence where EMC is mining, but the investment case now turns on two deliverables: converting the stockpile into cash and demonstrating that deeper mineralisation can move beyond Inferred status.
Questions in the middle?
- When will the first Mt Dimer toll-processing campaign commence, and what payable gold and recovery results will it deliver?
- How closely will mined grades and stockpile tonnes reconcile with the updated resource model?
- Can planned drilling convert deeper Inferred ounces into higher-confidence material without materially changing grade or scale?
