Highlights

  • MQR share price jumped 18.2% to AUD 0.013 per share on 5 September 2025 during trading.

  • Full suite of assays from the Mt Clement (Eastern Hills) Project confirmed robust antimony mineralisation with precious metal upside.

  • Maiden JORC-compliant Resource Estimate due in ~2 weeks, with Phase 2 RC drilling to commence late September 2025.

Marquee Resources Limited (ASX:MQR) has announced the receipt of the full suite of assay results from its maiden RC drilling campaign at the Mt Clement (Eastern Hills) Antimony/Gold Project in Western Australia. The program comprised 1,346 metres across seven RC holes, all of which intersected mineralisation.

The assays confirm multiple zones of antimony mineralisation, including the discovery of a new sub-cropping structure that could significantly expand the Project’s potential scale. Results have demonstrated consistent grades, further validating Mt Clement’s strategic position as a critical mineral supply opportunity.

Strategic Importance of Antimony

Antimony is listed as a critical mineral in Australia, the United States, and Europe due to its role in flame retardants, alloys, semiconductors, and military applications. With global supply heavily concentrated in China and Russia, the establishment of secure Western supply sources is of growing importance.

The Mt Clement Project adjoins Black Cat Syndicate’s (ASX:BC8) Eastern Hills JORC deposit, recognised as Australia’s largest undeveloped antimony resource. With strong assay results, Marquee positions Mt Clement as a cornerstone asset for building a secure antimony supply chain.

Key Assay Highlights

The final assays have confirmed multiple sub-parallel Sb-Pb bearing lodes associated with quartz-sulphide veining. Ore assemblages identified include boulangerite and jamesonite, alongside galena and arsenopyrite. Significant results include:

  • 8m at 1.05% Sb and 2.85% Pb from 137m, including 4m at 1.35% Sb and 3.55% Pb (MQRC390).

  • 8m at 1.02% Sb from 81m, including 4m at 1.48% Sb (MQRC394).

  • 9m at 0.88% Sb from 97m, including 4m at 1.41% Sb (MQRC391).

  • 2m at 1.96% Sb from 144m (MQRC394).

  • 3m at 1.27% Sb from 24m, including 1m at 2.31% Sb (MQRC392).

  • 3m at 5.33% Pb and 0.46% Sb from 58m, including 1m at 11.7% Pb (MQRC391).

These results confirm robust antimony and lead grades, supporting the company’s strategy to advance exploration rapidly.

Upcoming Milestones

Marquee has confirmed that a maiden JORC-compliant Mineral Resource Estimate (MRE) for the Mt Clement Project is expected within the next two weeks. This represents a significant near-term milestone in progressing the project toward development.

In addition, a Phase 2 RC drilling program is scheduled to commence in late September 2025. This campaign will target both depth and strike extensions, building upon the encouraging results achieved to date.

Share Price Performance

Following the announcement, Marquee’s share price increased by 18.2% to trade at AUD 0.013 per share on 5 September 2025.
