Achilles Antimony

The Achilles Antimony project is an advanced-stage exploration/near-term development antimony project, renowned as Australia’s highest grade primary antimony project

Resource Estimate

JORC 2012-Compliant Mineral Resource: 1.52 million tonnes at 1.97% antimony (Sb), containing 29,902 tonnes of antimony.
Additional Mineralisation: Enrichment in tungsten and gold, offering further exploration and development potential
Several exploratory drillholes have intersected ultra-high-grade antimony mineralisation up to 27.6% Sb outside the MRE, showcasing significant potential high-grade repetition deposits.

At its core, the Wild Cattle Creek deposit is recognised as Australia’s highest-grade undeveloped primary antimony resource.

Geological Setting

The deposit is within the Coffs Harbour Block of the New England Orogen, characterised by Late Carboniferous turbidite sequences, primarily the Brooklana Beds. These sediments have undergone multiple deformation events, regional metamorphism, and granitoid intrusions. The mineralisation style at Wild Cattle Creek is analogous to the nearby Hillgrove antimony-gold deposit, indicating a similar geological framework conducive to significant antimony and gold occurrences.

Historical Context

Discovered in the 1890s, Wild Cattle Creek has a history of antimony production, with reported grades reaching up to 46% Sb. Between 2005 and 2016, Anchor Resources conducted extensive exploration, including 23 drill holes, resource estimation studies, soil geochemistry, and environmental baseline surveys. This historical data provides a robust foundation for Trigg Minerals’ ongoing exploration and development activities.

Exploration Potential

The Achilles Project presents strong exploration potential, with mineralisation spatially associated with the Bielsdown Fault, a key structural corridor. Notably, antimony and tungsten grades increase towards the western margin of current drilling, where mineralisation remains open, highlighting a significant resource expansion opportunity.

Future Outlook

Trigg Minerals is committed to advancing the Achilles Project through targeted exploration and development programs aimed at expanding the current resource base and unlocking the full potential of the Wild Cattle Creek deposit. Ongoing studies will focus on delineating additional mineralisation zones, assessing metallurgical characteristics, and evaluating economic viability to support future mining operations.
