en.Wedoany.com Reported - Australia's GoldArc Resources (ASX:GA8) has completed multi-element analysis of samples from four drill holes at the Mt Stirling and Mt Stirling Well gold deposits, confirming a clear spatial association between high-grade gold mineralization and critical minerals at both deposits, providing additional information for the development of subsequent mining plans.

The multi-element analysis results show that at Mt Stirling, gold mineralization is consistently associated with elevated levels of arsenic, antimony, and tungsten. At Mt Stirling Well, gold is associated with elevated levels of silver, bismuth, and molybdenum.

Managing Director Paul Stephens stated that the company's focus remains on growing and developing the resources of these two gold deposits, and this multi-element work directly supports that objective. Metallurgical test work is underway and is expected to be completed in approximately four weeks, after which the mining implementation plan will be finalized with BML Ventures.

This is the first time GoldArc has conducted a full 59-element analysis on drill samples from Mt Stirling and Mt Stirling Well. Samples from all four diamond drill holes, excluding gold, were analyzed at Bureau Veritas in Kalgoorlie using a four-acid digestion method (including hydrofluoric acid, nitric acid, hydrochloric acid, and perchloric acid).

Stephens noted that this analysis provides a clearer picture of the occurrence state of gold in different deposits, and an additional benefit is the identification of antimony and tungsten, which coexist with gold, as critical minerals. Antimony and tungsten are highly valued and critical to the defense, aerospace, and renewable energy sectors, with Western markets actively seeking domestic and allied country suppliers to reduce reliance on China's supply chain.

The four drill holes totaled approximately 316 meters, targeting the core mineralized zones of M37/1306 (Mt Stirling) and M37/1305 (Mt Stirling Well). Significant intersections include: Hole 26MSDD001 at Mt Stirling intersected 5.6 meters at 8.71 g/t gold from 106.4 meters (including 3 meters at 15.53 g/t), associated with arsenic (8 meters at 1.9% from 106 meters), antimony (3.64 meters at 192 ppm from 106.4 meters), and tungsten (4 meters at 0.28% from 108 meters); Hole 26MSDD002 intersected 6 meters at 3.41 g/t gold from 11 meters (including 4 meters at 4.53 g/t), associated with arsenic (17 meters at 370 ppm from 3 meters) and tungsten (26 meters at 44 ppm from 0 meters). At Mt Stirling Well, Hole 26MSDD003 intersected 1.57 meters at 14.2 g/t gold from 47 meters (including 1 meter at 30.2 g/t), associated with silver (2.85 meters at 21.51 g/t from 45.82 meters), bismuth (97 ppm), and molybdenum (60 ppm); Hole 26MSDD004a intersected 1.25 meters at 2.86 g/t gold from 35.75 meters, associated with silver (1.55 meters at 25.31 g/t from 34.45 meters), bismuth (124 ppm), and molybdenum (71.6 ppm).

The Mt Stirling project is a high-grade gold asset within the Leonora North Gold Project in Western Australia, targeting open-pit mining. The project is operated by GoldArc, with BML Ventures fully funding capital and operating costs and managing mining activities, receiving 50% of net profits after cost recovery. GoldArc's tenement area in Leonora covers 936 square kilometers and is interpreted to share similar characteristics with nearby gold mines, including operations by Genesis Minerals (ASX:GMD), which has an established resource base containing 8.5 million ounces of gold.

These results enhance GoldArc's understanding of the geological model for both gold systems. The company continues to advance metallurgical and geotechnical work with BML Ventures and is conducting 34,000 meters of reverse circulation (RC) grade control drilling at Mt Stirling and Mt Stirling Well, with further results to be released. Baseline metallurgical test work is expected to be completed within four weeks, providing the basis for the final mining implementation plan. Additionally, selective re-analysis of mineralized zones within the Mt Stirling deposit will be conducted to test for elements such as arsenic, antimony, and tungsten to assess their economic potential.
