Brightstar Resources Limited (ASX: BTR) (Brightstar) is pleased to announce the second round of priority assay results from the remaining two metallurgical diamond drillholes at Cork Tree Well (CTW) within the Laverton Gold Project (LGP). These two holes were part of a broader 20 hole diamond drilling program1 which has now been successfully completed.
HIGHLIGHTS
- Assays received from the final two metallurgical diamond holes completed at Cork Tree Well with bonanza-grade gold assays up to 1028.37g/t Au
- High-grade results substantiated by numerous observations of visible gold in both drill holes
- Intercepts returned include 27.6m @ 17.77g/t Au from 51m (CTWMET003)
- CTWMET003 was drilled into the unmined central deposit at Cork Tree Well, with the gold mineralisation entirely contained within a dolerite - quartz breccia unit
- Intercepts returned below the historical shallow open pit within CTWMET001 include:
- 11.4m @ 3.1g/t Au from 133.5m (estimated true width), and
- 8.3m at 1.45g/t Au from 120.7m (estimated true width)
- Twenty-hole diamond drilling program successfully concluded with metallurgical and geotechnical testwork underway to feed into PFS workstreams
Brightstar’s Managing Director, Alex Rovira, commented “It is great to see further high-grades assays continuing and visible gold being observed from the diamond drilling program that has recently been completed at Cork Tree Well. CTWMET003 returned an excellent high-grade, shallow intersection of 27.6m @ 17.77g/t Au from 51m, which complements the previously announced2 intersections which included a strong result of 34.4m @ 7.94g/t Au (CTWMET004) drilled 1km to the north.
The drilling campaign represented the first diamond holes drilled at Cork Tree Well by Brightstar, with our understanding of the geology and mineralisation styles being strengthened by the knowledge being gained from this recently completed program.
Today’s results continue to reinforce our view that the gold mineralisation at Cork Tree Well is structurally hosted, with a mafic metadolerite host rock observed in CTWMET003 whilst gold mineralisation returned in CTWMET001 is positioned within the sedimentary package underneath the historically mined shallow open pit.
The four metallurgical drillholes (CTWMET001 – 004) were drilled into the known orebody locations that fall within the optimised $2,750/oz pit shells generated in the 2023 Scoping Study3, with CTWMET003 and CTWMET004 drilled down plunge to the orebody to deliver maximum rock mass for metallurgical testwork and CTWMET001 and CTWMET002 drilled perpendicular to the orebody and represent estimated true width.
Given the calibre of the assays received from the drilling to date, Brightstar continues to see strong potential to build on the existing 303koz @ 1.4g/t Au Mineral Resource4 both at depth with high-grade plunging shoots and strike extensions targeting the structurally-controlled mineralised trends. The high-grade results returned to date are significantly higher than the current 1.4g/t Au head grade of the Mineral Resource and 1.85g/t mine grade from the 2023 Scoping Study, representing significant upside.
We look forward to updating shareholders with more information on the diamond program, which forms the basis for metallurgical and geotechnical testwork workstreams within our ongoing Pre-Feasibility Study5.

Due to the nuggety and high-grade nature of the gold mineralisation observed in CTWMET001 and CTWMET003, multiple samples had repeat assays completed following from best QA/QC laboratory practice. The repeat fire-assays provided additional analytical insight into the nuggety nature of mineralisation in addition to the visible gold observed. Where multiple repeat assay runs occurred, an average of the results has been used in the reporting in Table 1 above and within this announcement. The full breakdown of the re-assayed samples are outlined below in Table 2-3.

Investor Insight
With multiple catalysts ahead, including resource upgrades, expanded production, and further development of its Laverton, Menzies, and Sandstone hubs, Brightstar Resources presents a compelling investment case in a rising gold market.
Overview
Gold has continued to demonstrate its resilience as a store of value, with prices peaking at US$3,500.05 per ounce, its all-time high. Amid ongoing global economic uncertainty, including inflationary pressures, rising geopolitical tensions, and volatile interest rate environments, investors have turned to gold as both a safe haven asset and a hedge against macroeconomic instability.
Brightstar Resources (ASX:BTR) is strategically positioned to capitalize on this environment as a low-cost, multi-asset gold developer with near-term production potential. The company controls over 1,500 square kilometers of highly prospective ground across three of Western Australia’s most prolific gold belts: the Laverton Tectonic Zone, the Menzies Shear Zone, and the Sandstone Greenstone Belt.
Unlike many junior exploration companies, Brightstar has a key differentiator: it owns a fully permitted, strategically located processing facility near Laverton. This existing infrastructure offers the company a critical advantage, enabling a low-capex restart scenario and faster time to cash flow compared to peers who must first secure permits and fund costly plant construction. This plant is subject of a DFS due for announcement in June 2025.
Through a focused multi-hub strategy, Brightstar has built a robust pipeline of development-ready and resource-growth projects, supported by:
- Over 3 million ounces of gold resources across Laverton, Menzies, and Sandstone;
- Ongoing high-grade drilling success in 2024 and 2025, including intercepts of up to 10m @ 43.8 g/t gold;
- A track record of low-cost, value-accretive acquisitions, such as Linden Gold Alliance and Alto Metals;
- A dedicated, in-house technical team executing on aggressive exploration, fast-tracked studies, and staged development.
With global gold demand remaining strong, Brightstar is well-positioned to deliver material shareholder value through its integrated production plan, supported by scalable infrastructure, a growing resource base, and access to capital. The company’s strategic approach includes combining brownfields development, organic exploration, and corporate M&A, placing it at the forefront of a new generation of Australian gold producers.
Company Highlights
- ASX-listed gold exploration and development company with a consolidated mineral endowment of 3 Moz of gold across Laverton, Menzies, and Sandstone hubs in Western Australia.
- Owns and operates 100 percent of project areas: 300 sq km in Laverton Tectonic Zone, 80 sq km in Menzies Shear Zone, and 1,200 sq km in Sandstone Greenstone Belt.
- Gold processing operations at the Laverton facility have commenced under an Ore Purchase Agreement (OPA) with Genesis Minerals Ltd (ASX:GMD), marking a significant milestone in transitioning from exploration to production.
- Recent drilling campaigns have yielded strong high-grade results, including:
- 16m @ 8.0 g/t gold at Second Fortune (Laverton)
- 10m @ 43.8 g/t gold at Musketeer (Sandstone)
- 16m @ 8.0 g/t gold at Yunndaga (Menzies)
- Following the successful Linden Gold Alliance acquisition, Brightstar has commenced a DFS for the wider development of its Laverton and Menzies assets which is due for release imminently in June 2025.
- Ongoing Sandstone drilling continues to return high-grade intercepts, further supporting project advancement and MRE conversion.
- In 2024, Brightstar signed a $4 million drill-for-equity deal with Topdrill to fast-track exploration at Sandstone.
- The company has successfully executed a US$11.5 million (AU$18 million) revolving stockpile finance facility with Ocean Partners Australia.

High-Grade Gold Confirmed at Bronzewing South
- Partial results received from the diamond tail of drill-hole BWSRC081 with the visible gold zone returning 15.5g/t Au over 0.48m from 416.5m. This high- grade zone is reported within a broader intercept of:
- 8.95m at 1.32g/t Au from 414m, including:
- 0.48m at 15.5g/t Au from 416.5m; and
- 0.55m at 3.52g/t Au from 422.4m.
- 8.95m at 1.32g/t Au from 414m, including:
- Follow-up drilling along strike from these intercepts is scheduled to commence in the coming days to define the extent of the south-trending zone of gold mineralisation with a diamond tail of drill-hole BWSRCD086.
- Drill results indicate the inadequacy of historical air-core drill testing with a significant search space now open on the boundary with the historical Bronzewing Mining Lease.
- Diamond drilling at the Central Target, located ~1.7km to the south of the Eastern Target and within the same structural corridor, has encountered zones of intense locally massive quartz veining associated with brecciation below historical Hammer gold drilling anomalies of:
- 20m at 1.5g/t Au from 120m in drill-hole BWSRC0037, including:
- 8m at 2.4g/t Au from 120m; and
- 4m at 3.9g/t Au from 120m.1
- 20m at 1.5g/t Au from 120m in drill-hole BWSRC0037, including:
- Assay results from the remaining program will be progressively released in the coming weeks.

Hammer’s Managing Director, Daniel Thomas, said:
“The confirmation of high-grade gold mineralisation at Bronzewing South is a significant step in our search for an economically viable gold target at our Yandal Gold Project. High-grade mineralisation can be traced with multiple intercepts to the north of our project area, with the mineralised structure interpreted to extend for hundreds of metres.
“We will now look to test this structure approximately 100m further south on our project area. We are very much looking forward to follow-up drilling at the Eastern Target, as we enter a zone without any previous drilling coverage.
“The team is encouraged by the observations in recent drilling at the Central Target and the potential for this corridor to be connected to the Eastern Target drilling some 1.7km to the north. This corridor is largely untested below the ineffectual air-core drilling and, with a prominent shear zone interpreted to connect these targets, it is of high interest to the team in our search for a significant gold discovery.”
