Petrographic Study Confirms Gold-Antimony Veining Near Hillgrove and Enmore

Petrographic Confirmation Strengthens Exploration Thesis

Critical Resources Limited (ASX – CRR) has announced the completion of a detailed petrographic study at its Amoco Gold-Antimony Project in the New England Fold Belt of New South Wales. The analysis, conducted by mineral systems expert Dr. Paul Ashley, identified structurally controlled quartz-sulphide veining consistent with orogenic gold-antimony systems, a hallmark of significant mineral deposits in the region.

This finding provides robust technical validation for Critical Resources’ exploration model, which targets fault-controlled corridors known to host high-grade gold and antimony mineralisation. The Amoco project’s proximity, just 19 km from Larvotto Resources’ Hillgrove operations and 14 km from Koonenberry Gold’s Enmore Project, places it within a fertile geological belt that has historically yielded valuable deposits.

Strategic Location and Geological Context

Situated along a southwest-northeast trending structural corridor, Amoco shares key geological features with its neighbours. The petrographic study revealed hydrothermal brecciation and quartz veining within fault-brecciated sedimentary rocks, alongside sulphide minerals such as pyrite and arsenopyrite. These minerals are commonly associated with gold in orogenic systems, suggesting the presence of mineralising fluids that have shaped the deposit.

Importantly, surface samples from the area have returned encouraging grades, including assays of up to 17.9 grams per tonne gold and 0.7% antimony. The presence of weathering minerals like scorodite and goethite further indicates that the system has been exposed near surface but retains key textures to guide exploration.

Next Steps – Soil Sampling and Drilling Permits

Building on these findings, Critical Resources is preparing to launch a systematic soil-geochemistry program designed to map the extent of mineralisation along priority structures. Field crews are scheduled to mobilise in early July 2025 to collect detailed geochemical data, which will inform drill targeting and help define the scale and orientation of the mineralised system.

Meanwhile, the company is progressing permitting for its maiden drill program with the New South Wales Resources Regulator. Land access agreements are also being negotiated with landowners, marking important steps toward unlocking the project’s potential.

Broader Portfolio and Strategic Outlook

Critical Resources is actively exploring multiple projects, including the Mavis Lake Lithium Project in Canada and the Hall Peak Base Metals Project in New South Wales. The Amoco project complements this portfolio by targeting high-value gold and antimony mineralisation within a proven geological setting. The recent petrographic confirmation and advancing exploration activities underscore the company’s commitment to de-risking and advancing its assets for shareholders.
