Sinclair Gold (ASX:SGC) has doubled the resource estimate at its Mt Henry Gold Project in Western Australia to 48 million tonnes at 1.2 grams per tonne gold for 1.8 million ounces.
The updated mineral resource estimate (MRE) adds 900,000 ounces of contained gold to the 900,000 ounces already in place when Sinclair Gold acquired Mt Henry in February 2026.
All the resource growth came from the Mt Henry and Selene deposits and includes results from 20,426m of drilling completed as part of a planned 50,000m program.
The current drilling program is initially targeting extensions to the two deposits and will target the broader 16km mineralised corridor, including Birthday Gift, Artemis, and Plutus, where large areas remain undrilled.
Assays are pending from a further 25 holes drilled outside the current resource footprint, with results from many expected imminently. These results will provide further information on the potential for further resource growth beyond the current MRE footprint.
CEO Jeff Sansom says the resource upgrade is an “outstanding result” and validates what the company saw in the project when it was acquired.
“Both Mt Henry and Selene remain open, we are already drilling outside the current MRE, and we have assays pending from 25 holes drilled beyond the resource. There is still a lot more drilling to do across both deposits and this all points to further growth,” Sansom says.
“And that is before we really start testing the broader project. Birthday Gift, Artemis, and Plutus have all returned strong historical results, while large parts of the 16km mineralised corridor have seen very little exploration.
“We are looking forward to getting into those areas as we progress our drilling because, ultimately, we believe Mt Henry has the potential to become a substantially larger, multimillion-ounce gold project.”
The Mt Henry Project sits within a highly prospective 16km mineralised corridor which hosts the existing resources and a pipeline of regional gold targets. Within that corridor, the mineral resources sit within 11km of granted mining tenure, with access to existing regional infrastructure.
Sinclair Gold is a Western Australian explorer and developer focused on the Mt Henry Project located in the Eastern Goldfields of WA.
