Marquee Resources Confirms High-Grade Antimony at Mt Clement ahead of Maiden JORC MRE

Marquee Resources (ASX: MQR) has reported consistently high-grade antimony from Phase 1 drilling program at its Mt Clement (Eastern Hills) project in Western Australia.
The full suite of assays has highlighted robust mineralisation across all holes drilled, with additional gold, silver and lead credits adding upside to the results.
A maiden JORC-compliant mineral resource estimate (MRE) is due within two weeks, with Marquee to begin Phase 2 drilling later this month targeting depth and strike extensions.
Consistent Mineralisation Across Program
The initial seven-hole, 1,346-metre reverse circulation campaign confirmed multiple zones of antimony mineralisation, including new sub-cropping structures that could significantly expand project scale.
Intercepts included 8m at 1.05% antimony and 2.85% lead from 137m, and 9m at 0.88% antimony from 97m, with several higher-grade sub-intervals and all holes intersecting mineralisation, confirming extensions of known structures while pushing mineralisation eastward by more than 250m.
The deepest hole demonstrated continuity at depth, returning 20m at 0.26% Sb from 232m and indicating widening mineralisation zones.
Marquee said the results validate its strategy of aggressively advancing exploration and development at Mt Clement, which sits adjacent to Black Cat Syndicate’s Eastern Hills resource, described as Australia’s largest undeveloped antimony deposit.
Company’s Confidence Confirmed
Executive chair Charles Thomas said the results confirmed the company’s confidence in the project.
“These full suite of results underscore the potential of our Mt Clement (Eastern Hills) Project to emerge as one of Australia’s premier antimony projects,” he said.
“Every hole drilled confirmed continuity of high-grade Sb mineralisation, with meaningful contributions from lead, silver and gold adding further value.”
He sees the upcoming MRE as a significant milestone, noting strong global market recognition of antimony’s strategic importance.
“Marquee is advancing Mt Clement at the right time, in the right commodity, and now with strong tail winds behind us for exploration and resource definition,” he said.
Next Steps in Exploration
The company expects that maiden MRE to establish a baseline for further project development, with Phase 2 drilling to begin in the last week of September and focus on depth and strike extensions highlighted by Phase 1.
Marquee is also advancing its plans for a Phase 3 campaign before the end of 2025, aimed at building on the continuity of mineralisation and expanding potential scale.
The Mt Clement project sits at the western end of the Ashburton Basin, approximately 30km southwest of Black Cat Syndicate’s (ASX:BC8) Paulsens gold mine.
