Devon Pit Yields Gold Grades Over 220 g/t, Processing Brought Forward
Matsa Resources has intersected a high-grade visible gold pocket at its Devon Pit Gold Mine, prompting an accelerated ore processing schedule and an earlier-than-expected first gold pour.
- Visible gold pocket discovered outside original mine plan
- Photon assays confirm exceptionally high gold grades over 180 g/t
- Ore haulage and processing advanced by one week
- First gold pour now expected mid-September 2025
- Devon Pit mine reserve targets 46,000 ounces over 18 months
Discovery of Visible Gold Pocket
Matsa Resources Limited has revealed a significant development at its Devon Pit Gold Mine with the discovery of a pocket of visible gold. This high-grade gold was found in brecciated gabbro and pyroxenite rock formations, notably outside the original digblock design and reserve mine plan. The location is near a historical mine shaft, underscoring the rich gold potential of the site.
Exceptional Assay Results Confirm High Grades
Photon assays conducted at the ALS Kalgoorlie laboratory returned impressive grades of 222.60 grams per tonne and 188.35 grams per tonne from two samples. Photon assaying, a non-destructive technique using high-energy X-rays to detect gold, has confirmed the presence of this high-grade mineralisation, which is rare and highly sought after in gold mining.
Operational Impact and Accelerated Processing
In response to this discovery, Matsa has accelerated ore haulage to FMR’s Greenfields processing plant. The company has brought forward its first ore processing campaign by one week, now scheduled to start on 11 September 2025. This adjustment aims to capitalise on the high-grade ore, with the first gold pour anticipated on 15 September 2025, followed shortly by delivery of gold doré to the Perth Mint for refining.
Strategic Significance for Devon Pit Mine
The Devon Pit Gold Mine, which includes several historical shafts and underground workings dating back to the 1920s, currently holds a reserve of 309,000 tonnes at an average grade of 4.59 grams per tonne, targeting approximately 46,000 ounces of gold. The mine is expected to operate for around 18 months, producing in excess of 40,000 ounces. This visible gold pocket discovery adds a promising dimension to the mine’s production profile.
Looking Ahead
Executive Chairman Paul Poli expressed enthusiasm about the find, highlighting the geological significance of the linking shear zone between two rock types, which appears to host this high-grade gold. The accelerated processing schedule and imminent gold pour mark an exciting phase for Matsa, its mining partners, and shareholders.
Bottom Line?
Matsa’s visible gold discovery at Devon Pit could redefine near-term production and investor expectations.
Questions in the middle?
- Will further high-grade pockets be identified beyond the current discovery?
- How will this discovery impact the overall mine plan and reserve estimates?
- What are the expected financial implications of processing this high-grade ore earlier?
