Brightstar Resources has reported exceptional high-grade gold intercepts from recent drilling at its Lord Byron deposit, significantly exceeding expectations and prompting plans for further exploration.
- 32m @ 7.16g/t Au intercept beneath current open pit design
- Drilling targets upgrade from inferred to indicated resource classification
- Lord Byron deposit hosts 251koz @ 1.5g/t Au within Laverton Hub
- Follow-up drilling planned to expand high-grade mineralisation
- Multiple rigs active across Brightstar’s Laverton and Sandstone projects
Exceptional Drilling Results at Lord Byron
Brightstar Resources Limited (ASX:BTR) has announced standout results from a 1,100-metre reverse circulation drilling program at its Lord Byron gold deposit, part of the company’s broader Laverton Hub in Western Australia. The highlight is a remarkable 32-metre intersection grading 7.16 grams per tonne gold starting at 69 metres depth, including an 11-metre section at an impressive 15.1 grams per tonne. This intercept lies beneath the current optimised open pit design, signaling potential for resource expansion.
Context Within Brightstar’s Portfolio
Lord Byron, located about 10 kilometres west of Brightstar’s active Fish mine at Jasper Hills, currently holds a Mineral Resource Estimate of 251,000 ounces at 1.5 grams per tonne gold. The deposit is a key component of Brightstar’s 0.9 million ounce Laverton Hub, which is strategically positioned roughly 50 kilometres from the company’s proposed 1 million tonnes per annum carbon-in-leach processing plant. The recent drilling focused on infilling and extending the inferred mineral resource within and just south of the Definitive Feasibility Study’s optimised pit shell, aiming to upgrade resource confidence and potentially add to Ore Reserves.
Implications and Next Steps
Brightstar’s Executive Director of Operations, Andrew Rich, described the results as surpassing expectations, particularly noting the rarity of intercepts exceeding 200 gram-metres at this deposit. The high-grade zones intersected are open at depth, suggesting further mineralisation remains to be delineated. The company is actively planning follow-up drilling to better define this newly identified wide, high-grade shoot. Meanwhile, Brightstar continues to operate multiple rigs across its portfolio, including underground diamond drilling at Laverton’s Fish deposit and surface drilling at the Sandstone Hub.
Technical and Geological Insights
The mineralisation at Lord Byron is hosted within amphibolite and interbedded chert and banded iron formations, with quartz veining in altered mafic amphibolite. The drilling was designed to intersect mineralised zones perpendicularly, providing reliable assay data. The recent program’s results include other significant intercepts such as 30 metres at 3.02 grams per tonne and several narrower high-grade zones, reinforcing the deposit’s robust grade profile.
Strategic Outlook
These results come at a pivotal time as Brightstar advances its feasibility studies and development plans for the Laverton and Menzies hubs. The potential to upgrade resources and extend mine life at Lord Byron could enhance the economics of the proposed processing plant and overall project viability. Investors and analysts will be watching closely for the outcomes of the planned follow-up drilling and any subsequent resource updates.
Bottom Line?
Brightstar’s Lord Byron drilling breakthrough sets the stage for resource upgrades and deeper exploration.
Questions in the middle?
- How will follow-up drilling impact the classification and size of the Lord Byron resource?
- What are the economic implications of high-grade zones below the current pit design?
- Could these results accelerate Brightstar’s timeline for the Laverton processing plant?
