Brightstar Resources Limited reports outstanding drilling results at its Sandstone Hub. High-grade gold intercepts from the Lord Nelson, Havilah, and Bull Oak deposits bolster resource potential—supporting prospects for open pit mining and future value growth, a promising development for investors and emerging traders.
Brightstar Resources Limited has reported that its ongoing drilling at its Sandstone Hub continues to deliver encouraging gold intercepts across three major deposits—Lord Nelson, Havilah and Bull Oak. The company’s latest reverse circulation drilling program of approximately 5,300 metres has focused on extending and infilling mineralisation with the aim to upgrade its resource classification ahead of an economic study. At the Lord Nelson deposit, a series of significant intercepts were recorded, including a 32‐metre section averaging 3.44 g/t gold (with 17 metres at 5.44 g/t) and several other intercepts showing high-grade zones in a pit shell optimised at a gold price of $2,500 AUD per ounce. These intercepts confirm the continuity of thick mineralisation within a design that may support future open pit mining operations.
The campaign has also yielded promising results at the Havilah deposit, where a 3‐metre intercept returned an impressive 11.4 g/t gold, with a sub‐interval reaching nearly 30 g/t. This high-grade mineralisation, found further down the plunge of the deposit, suggests that additional follow-up drilling could lead to an expanded mineral resource. At the Bull Oak deposit, drilling has extended the known deposit at depth, with intercepts showing both broad low-grade zones alongside narrower, high-grade veins—some small segments recording values above 10 g/t. These results are being interpreted in the context of advancing geologic understanding, fueling further exploration including geophysical surveys to test uncharted felsic intrusive targets.
The technical details highlight a well-planned drilling strategy. For example, the intercepts at Lord Nelson include multiple intervals with grades ranging from around 1.2 g/t to over 20 g/t in very localized, narrow segments. The detailed spatial and geological data—such as drill hole orientations and down-dip drilling—support the interpretation of a complex mineralised system hosted within granodiorite and related intrusive rocks. Moreover, Brightstar’s larger drilling campaign for calendar year 2025, which totals over 130,000 metres, reinforces the commitment to growing its resource base across the region.
Investors might view the news with cautious optimism. On the bullish side, the continuation of high-quality intercepts, new high-grade targets, and infill drilling designed to enhance resource classification could propel positive sentiment and add value, especially if the potential for open pit mining and resource expansion develops as forecast. The technical consistency and the integration of multiple deposits within a single hub provide a solid geometric framework that could benefit the overall project valuation.
Conversely, some bearish considerations remain. While high-grade zones are evident, the broader low-grade envelope and the inherent uncertainties of exploration, such as eventual mining costs and geological complexities including dilution effects, could temper expectations. As further drilling and resource updates are awaited, market participants will remain attentive to additional assay results and updates that may either confirm or challenge the current positive outlook.
Overall, the results underscore a significant milestone in Brightstar Resources Limited’s exploration program, providing both immediate technical highlights and setting the stage for further resource growth in the Sandstone district.
