Brightstar Resources Limited reveals outstanding results from its Yunndaga drilling program in Menzies, with high-grade gold intercepts such as 16m at 8g/t Au. These findings enhance confidence in a significant underground opportunity as further resource expansion is planned.
Brightstar Resources Limited has reported encouraging outcomes from its Phase 1 reverse circulation drilling program at the Yunndaga Deposit, a key asset within the Menzies Gold Project. The program, which encompassed approximately 6,100 meters of drilling, achieved exceptional intercepts including 16 meters at 8.03 grams per tonne gold from 220 meters depth. Notably, within this interval, finer-scale results included a 1-meter section registering 33.6 g/t gold and an adjacent 4-meter section at 13.5 g/t. Additional significant intercepts, such as 13 meters at 4.70 g/t from 167 meters (including 2 meters at 22.6 g/t), further underscore the high-grade potential of the deposit.
These results validate the technical approach of infilling areas within optimized stope boundaries and testing for down-dip extensions, confirming the presence of classic Menzies-style lodes with a characteristic pinch-and-swell morphology and nuggety grade distribution. Historical operations in the vicinity have yielded over 270,000 ounces at high grades, reinforcing the geological potential of the area. The current resource, estimated at 3.4 million tonnes at 1.4 g/t gold, stands to be upgraded as the company advances its drilling campaign. Brightstar’s plans for a second phase starting in June, which will integrate both reverse circulation and diamond drilling techniques, aim to further extend resource volumes and probe at depth for additional high-grade zones.
The technical indicators—from intercept lengths to detailed grade variations—suggest robust mineral continuity and support the possibility of a sizeable underground mining operation. The company’s drilling results include other notable intercepts such as 11 meters at 3.32 g/t, 12 meters at 2.34 g/t (with a 1-meter section at 11.4 g/t), 8 meters at 3.45 g/t (including 1 meter at 20.6 g/t), and 7 meters at 2.65 g/t, all aligning with the established deposit model in the region.
From a bullish perspective, these drilling outcomes are likely to generate investor interest, as the strong high-grade intercepts and the outlined expansion strategies not only upgrade the current mineral resource but also set the stage for near-term underground mining production. The detailed technical data and promising sub-surface continuity support optimism about an improved asset valuation and increased mining potential.
Conversely, a bearish view might point to the inherent risks in “nuggety” deposits, where grade variability could present challenges in resource estimation and mine planning. The upcoming second phase of drilling introduces additional uncertainties, particularly with the need to confirm the deeper extents of mineralization. This cautious stance is compounded by potential delays or technical difficulties as the company transitions from exploration to resource development.
Brightstar Resources Limited continues to build its project portfolio with further drilling campaigns planned across its Sandstone and Laverton Hubs. As the exploration program progresses, market participants will closely monitor these developments, weighing the promising technical results against the challenges inherent in advancing underground resource projects.
