Lauriston’s Antimony Discovery Raises Questions on Resource Expansion and Processing Challenges

Exploration Breakthrough at Lauriston

Adelong Gold Limited (ASX – ADG) has revealed compelling new assay results from its Lauriston Gold Project in Victoria, Australia, confirming high-grade antimony (Sb) mineralisation alongside gold at the Comet discovery. This marks the first systematic antimony sampling of historic drill core, uncovering grades as high as 10.3% Sb over narrow intervals, coupled with gold values exceeding 3 g/t. These findings reinforce Lauriston’s geological affinity with renowned Victorian Au-Sb systems such as Fosterville and Costerfield, known for their multi-commodity richness.

Strategic Location and Geological Parallels

The Lauriston Project’s adjacency to Agnico Eagle’s Fosterville Mine, one of the world’s highest-grade and lowest-cost gold operations, adds significant strategic value. Hosted within the same Ordovician sedimentary rocks and sharing key structural features, Lauriston’s mineralisation is characterised by epizonal gold-antimony systems formed under shallow crustal conditions. The Comet discovery, situated within the structurally analogous Comet Anticline and Fault Zone, has already delivered impressive gold intercepts, and the new antimony results add a valuable dimension to the project’s resource potential.

Multi-Commodity Upside and Next Steps

Adelong Gold’s Managing Director Ian Holland emphasised the significance of these results, highlighting the potential for a multi-commodity outcome that could enhance the project’s economic profile. The company plans to expand systematic antimony sampling along the Comet-Trojan structural corridor, integrating this data into updated geological models to refine targeting. Follow-up drilling will focus on testing both depth and lateral extensions of the high-grade zones, aiming to unlock further mineralisation and better understand the distribution of antimony relative to gold.

Broader Portfolio and Growth Prospects

Lauriston complements Adelong Gold’s broader Victorian portfolio, including the Apollo Gold and Antimony Project, and the flagship Adelong Goldfield Project in New South Wales. The company also holds lithium assets in Brazil, positioning itself across multiple commodities aligned with global demand trends. With exploration momentum building at Lauriston and a clear path to resource expansion, Adelong Gold is advancing towards unlocking significant value in a highly prospective region.
