Achilles Antimony Project

The Achilles Project is centred around the Wild Cattle Creek antimony deposit, Australia’s highest-grade undeveloped antimony resource, 40km west of Coffs Harbour, NSW. With a JORC 2012-compliant Mineral Resource Estimate of 1.52Mt at 1.97% antimony (Sb), containing 29,902 tonnes of antimony, the project also benefits from enrichment in tungsten and gold, providing additional growth potential.

Discovered in the 1890s, the project has historically produced antimony ore during several periods of operation since then, with grades up to 46% Sb reported. Anchor Resources completed the most recent work on the project from 2005 to 2016 when it completed 23 drill holes, two resource estimation studies, orientation soil geochemistry, water and noise monitoring surveys, and sponsored university research into the genesis of the Wild Cattle Creek deposit.

The Wild Cattle Creek deposit is in the Coffs Harbour Block of the New England Orogen, within a Late Carboniferous turbidite sequence dominated by siltstone (the Brooklana Beds). These sediments have undergone multiple deformations, regional metamorphism (up to biotite grade), and granitoid intrusions. The block is interpreted as an accretionary prism with subduction-related metamorphism dated at 318 ± 8 Ma. Mineralisation at Wild Cattle Creek is like the nearby Hillgrove antimony-gold deposit, 80km west-southwest and currently held by Larvotto Resources (ASX: LRV). Wild Cattle Creek is one of ~235 antimony occurrences in the New England region of NSW.

JORC 2012 Resource
The Wild Cattle Creek antimony mineral resource estimate, prepared by SRK Consulting in September 2013 in accordance with 2012 JORC, was based on 130 surface drill holes totalling 10,710 metres. The deposit is exposed at the surface for over 300 metres and plunges approximately 25° westerly. It extends down plunge for over 350 metres, where mineralisation remains open to the west.
