High-Tech Metals Ltd. has reported an upgrade to its Mt Fisher gold project in Western Australia, expanding the site’s contained gold resource by 47 per cent to 51,000 ounces.
The updated JORC (2012) mineral resource estimate (MRE) totals 800,000 tonnes at 2 grams per tonne (g/t) gold, up from the project’s 2022 resource estimate of 464,400 tonnes at 2.32 g/t gold for 34,700 ounces, representing a 72 per cent increase in total tonnage.
The updated MRE incorporates results from the company’s 6,038-metre Phase 1 reverse circulation (RC) drilling program completed earlier this year.
The campaign extended open-pit mineralisation across a 770-metre strike length down to approximately 160 metres below the natural surface.
The upgrade defines a maiden underground Inferred Resource beneath the optimised open-pit shell, standing at 280,000 tonnes at 3.0 g/t gold for 27,000 ounces.
Overall, the updated resource comprises 13,000 ounces in the Indicated category, 38,000 ounces in the Inferred category, and a surface chert stockpile of 150,000 tonnes at 0.9 g/t gold containing 4,300 ounces.
High-Tech Metals CEO James Merrillees noted the significance of the dual open-pit and underground classification.
“The updated Mt Fisher Mineral Resource is an important step forward for the project, increasing contained gold by 47 per cent to 51,000 ounces and providing a much clearer picture of the mineralised system,” Merrillees said.
“The 2026 drilling program has materially improved our understanding of the geological controls on mineralisation and confirmed that the system continues beyond the previous Resource and beneath the historical pit.”
Merrillees added that mineralisation remains open to the north and down plunge, offering further potential for resource growth.
Following minor contractor delays, Phase 2 RC drilling is now scheduled to commence in late September to target down-plunge extensions and high-grade targets.
“This drilling will target further resource growth and conversion, with a particular focus on the areas identified by the updated geological model.”
