Bonanza-grade gold unearthed at Aurora Tank

Titanium-rich heavy mineral sands discovered at Muckanippie

Heap leach testing shows gold recoveries up to 93%

Marmota (ASX:MEU) has delivered a standout quarter marked by high-impact drilling results at its flagship Aurora Tank gold project and a promising discovery of valuable heavy mineral sands at Muckanippie in South Australia. The latest findings add significant momentum to the company’s exploration efforts in the Gawler Craton region.

The company intersected “bonanza” gold grades at Aurora Tank, with assay values reaching an impressive 107 grams per tonne (g/t). Notably, five intersections from the recent campaign exceeded 20g/t, and 13 returned grades above 10g/t. These figures underscore the project’s near-surface high-grade potential and strengthen the case for further development.

Adding to the optimism, Marmota also conducted bulk leach extractable gold (BLEG) tests which showed a 73% improvement in assay grade, reaching an average of 87g/t. Three of the five BLEG samples recorded assays over 90g/t, further confirming the project’s gold richness.

Metallurgical testing undertaken post-quarter has also been encouraging. The process focused on assessing the feasibility of a low-cost, low-capital heap leach operation. These tests delivered exceptional gold recoveries of up to 93%, pointing to a potentially economical pathway for production.

According to company statements, Aurora Tank combines high-grade results with favorable metallurgy, making it a strong candidate for a simple open-pit heap leach mining approach. This is particularly significant as the broader gold market continues to rally amid strong fundamentals, enhancing the strategic value of Marmota’s position within a 10,000-square-kilometre tenement in South Australia’s Gawler Craton.

In parallel with the gold success, Marmota’s maiden exploration at Muckanippie unveiled a heavy mineral sands discovery rich in titanium-bearing minerals. X-ray diffraction scans of samples reported an average of 79% valuable heavy mineral (VHM) content, with some results hitting as high as 90% VHM. This includes high concentrations of rutile and pseudorutile, notably in the northern zones starting from surface level.

These twin discoveries place Marmota in a strong position, not only in precious metals but also in industrial minerals critical to a range of high-tech and green technologies.
