Brightstar Resources Limited announces encouraging RC drilling results at its Sandstone Hub. The Bull Oak deposit shows high-grade intercepts with potential for large-scale mining, while early hits at the Sandstone North prospect further affirm promising resource growth for future development.

Brightstar Resources Limited has announced new results from its ongoing drilling program at the Sandstone Hub in Western Australia’s East Murchison region. The company’s extensive +80,000m infill and extensional drilling campaign continues to reinforce its current 1.5 million ounce at 1.5 g/t gold mineral resource. Recent assay data from reverse circulation drilling includes notable intercepts at the Bull Oak deposit, where one hole returned 178m at 0.70 g/t gold starting at 16m. Within this extended interval, high-grade segments were identified with one meter returning as high as 20.5 g/t gold and another at 8.94 g/t gold. These findings complement earlier results, including intercepts of 106m at 0.60 g/t and 167m at 0.59 g/t gold, lending further credibility to an established exploration target beneath the current resource. The Bull Oak deposit, hosted within a granodiorite intrusion with a strike length of approximately 500m and steep dipping boundaries, contains multiple high-grade quartz reefs embedded within broader low-grade halos. The technical overview details that these structures occur both within the intrusive body and extend into surrounding mafic rocks, suggesting material potential for bulk-tonnage open pit operations. Meanwhile, early-stage drilling at the Sandstone North prospect returned promising intercepts—such as 2m at 7.54 g/t gold and 5m at 3.17 g/t gold—indicating significant shallow mineralisation beneath historical workings. The technical indicators, including consistent high-grade intercepts integrated within lengthy lower-grade intervals, underline the continuity of mineralisation and further validate the exploration target set at Bull Oak. The program has employed industry-standard reverse circulation drilling protocols, with detailed logging and quality control measures ensuring the reliability of the assay results. In addition, the company is planning to follow up these findings with larger-scale RC and diamond drilling programs later in the year, and a second rig is already active at the Laverton Hub. There is a bullish sentiment supported by the strong assay results, the discovery of high-grade zones within a substantial mineralised envelope, and the potential for resource growth at both Bull Oak and Sandstone North. Investors may view the promising drill intercepts and the prospect of scaling up operations as positive indicators for long-term value creation. Conversely, the bearish side considers the challenges associated with early-stage exploration at Sandstone North, where intercept widths and true widths remain to be fully established. Additionally, while high-grade segments are encouraging, the overall lower grade of some extended intercepts and typical delays caused by weather conditions may introduce short-term uncertainties. Technical challenges inherent in extrapolating drill results to commercial-scale mining operations also warrant caution. Brightstar Resources Limited’s systematic drilling approach and robust technical review process suggest significant resource potential, though as with all early-stage exploration, investors should remain mindful of inherent risks and uncertainties during these formative phases.
