Brightstar Resources Limited has boosted resource estimates at its Laverton and Menzies gold sites. Extensive 2024 drilling has increased deposit quality and grade, laying strong foundations for near-term production and DFS progress in Western Australia’s prolific Goldfields region.
Brightstar Resources Limited has released news highlighting major upgrades to its Mineral Resource Estimates across its Laverton and Menzies assets. Extensive 2024 drilling programs—comprising reverse circulation and diamond drilling—have resulted in improved resource confidence ahead of the upcoming Definitive Feasibility Study expected in the first half of 2025. The company’s recent work has not only provided the first in‐house estimates for several deposits but also increased both tonnage and grade at key sites.
The updated estimates indicate that the company’s measured and indicated resources surpass one million ounces of gold, with over 300,000 ounces in assets already producing or ready for near-term production. Notable improvements include a 34% increase in the measured and indicated ounces at the Lord Byron deposit (251,000 oz at 1.5 g/t Au), a 25% grade increase at the Lady Shenton System deposit (273,000 oz at 1.5 g/t Au), and similar enhancements at other deposits such as Fish, Cork Tree Well, Second Fortune, and Link Zone. These technical refinements have been achieved using rigorous geological modelling and interpolation techniques, with drill spacing from 1984 to 2024 contributing to reduced geological risks later used to underpin successful future mining operations.
The drilling programs were designed to de-risk the mining areas while feeding updated resource data directly into the DFS workstreams. This includes a focus on infill drilling and depth extensions across productive zones in both projects. Additional drilling planned for 2025 at areas like the Yunndaga deposit is expected to yield further resource enhancements and potentially more robust economic models, with upgraded estimates influencing mining design schedules and budgets.
Bullish sentiment is supported by the significant resource upgrades and improved grade profiles that de-risk the projects and enhance the company’s near-term production potential. The technical rigor and comprehensive data sets adopted increase confidence in progressing towards production, which could lead to stronger cash flow generation as DFS outputs materialize. Conversely, some caution remains for beginner investors, as the final economic viability and mining design details will be clarified only upon completion of the DFS, leaving some execution and market risk in the short term. Overall, this announcement signals a positive trajectory in Brightstar’s asset portfolio, though investors should remain mindful of the inherent exploration and development risks that persist in the mining industry.
