Brightstar Resources Limited (ASX: BTR) (Brightstar or the Company) is pleased to announce the second round of non- priority assay results from sixteen Geotechnical diamond drillholes at Cork Tree Well (CTW) within the Laverton Gold Project (LGP). These sixteen holes were part of a broader 20-hole diamond drilling program2 designed for metallurgical and geotechnical purposes.
HIGHLIGHTS
- Assays received from eight geotechnical diamond holes completed at Cork Tree Well with gold assays up to 40.15g/t Au, located near CTWMET003 which returned 27.6m at 17.77g/t Au from 51m1
- Intercepts returned include 4.0m @ 17.32g/t Au from 78.0m (CTWGT004), including:
- 1.0m at 40.15 g/t Au from 78.0m, and
- 0.59m at 37.4 g/t Au from 81.0m, and
- 0.41m at 11.62 g/t Au from 81.59m
- Additional lode within CTWGT004 returned 3.0m at 3.46 g/t Au from 68m including 1.0m at 8.48 g/t Au from 70m
- Shallow intercept returned from CTWGT003:
- 2.6m at 1.74g/t Au from 33.0m
- High-grade results at the base of current pit shell design provides confidence for continuous mineralisation extensions at depth with historically defined significant intercepts
- CTWGT003 and CTWGT004 were drilled into the unmined material north of the historically mined northern pit at Cork Tree Well, with the gold mineralisation entirely contained within a sheared mafic/ultramafic sequence
Brightstar’s Managing Director, Alex Rovira, commented “It is pleasing to see further high-grade assays continuing from geotechnical holes from the diamond drilling program that was completed at Cork Tree Well earlier this year. CTWGT004 returned a significant high-grade intersection of 4.0m @ 17.32g/t Au from 78.0m, which complements the previously announced1 intersection of 27.6m @ 17.77g/t Au (CTWMET003) drilled 200m to the north.
The sixteen Geotechnical drillholes (CTWGT001 – CTWGT016) were drilled into the current optimized $2,750/oz pit- shells generated in the 2023 Scoping Study3 with these holes designed by Brightstar’s independent geotechnical consultants targeting structural and rock mass data for the definitive feasibility study. Both CTWGT003 and CTWGT004 were drilled perpendicular to the orebody and thus reported intersections represent estimated true widths of significant mineralised intercepts.
Given the quality of the assays received from the drilling to date, Brightstar is excited to build on the existing 303koz @ 1.4g/t Au Mineral Resource4, which is open both at depth with high-grade plunging shoots and along strike 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 to both metrics.”

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.

Key Projects
Silver Queen Project
The Silver Queen project is Equity Metals’ 100 percent owned flagship asset located in central British Columbia’s prolific Skeena Arch, approximately 35 km south of Houston. This 18,871-hectare property consists of 17 crown-granted titles and 46 tenure claims in the Omineca Mining Division. Surrounded by past-producing and active mines, including the Equity silver mine, Berg, Endako and Mt. Milligan, the project benefits from established infrastructure such as roads, power and rail access.
Silver Queen hosts a high-grade polymetallic system featuring silver, gold, copper, lead and zinc mineralization. The project is underpinned by a robust NI 43-101 compliant resource estimate (as of December 2022) consisting of 62.8 million ounces (Moz) silver-equivalent (AgEq) in the indicated category grading 565 grams per ton (g/t) AgEq, and 22.5 Moz AgEq in the inferred category grading 365 g/t AgEq. This includes 3.46 million tons (Mt) of indicated resources averaging 189 g/t silver, 2.13 g/t gold, 0.24 percent copper, 0.6 percent lead, and 3.5 percent zinc, and 1.92 Mt of inferred resources grading 167 g/t silver, 0.82 g/t gold, 0.23 percent copper, 0.5 percent lead, and 2 percent zinc.
The mineralization occurs in multiple steeply dipping epithermal vein systems, subdivided into the No. 3, NG-3, Camp and Sveinson veins. Each exhibits distinct metal zonation – the Camp veins are silver-dominant, while the Sveinson, No. 3 and NG-3 show a stronger gold bias. Bonanza grades have been intercepted at multiple locations, including down-hole drill core intervals assaying up to 56,115 g/t silver over 0.3 metres in recent drill results. High sulphide and low sulphide vein environments have both been identified, suggesting a long-lived and multi-phase mineralizing event.
Since late 2020, Equity has completed 52,877 meters of drilling in 146 holes, targeting extensions and new zones of mineralization. In 2024 alone, four target areas – George Lake, Camp North, No. 3 North and Camp-Sveinson – were tested via 17,209 meters across 42 holes. Drilling resulted in the delineation of a 550-metre strike-length for mineralization in the George Lake target and a 400-metre strike-length for mineralization in the No. 3 North target, as well as several extensions of earlier identified veins in the Camp Deposit and a new discovery in the Camp North target. A 6,000-meter 2025 drilling program will further test these zones with updated modeling and resource growth expected in Q3 2025.
Metallurgical testing completed in both 1988 and 2022 yielded positive recoveries: 83 percent gold, 95 percent silver, 93 percent copper, 91 percent lead, and 98 percent zinc. A follow-up metallurgical program is planned to support preliminary development studies. With extensive underground development (~9 km of historic workings) and proximity to key infrastructure, the Silver Queen project is well positioned for advancement toward economic studies and ultimately, a potential strategic transaction.
Arlington Project
The Arlington project is a 3,584-hectare, early-stage exploration asset located in southern British Columbia’s Greenwood Mining Division, approximately 65 km south of Kelowna. The project sits within the prolific Quesnel Terrane and is accessible year-round via Highway 33 and a network of logging roads. The region hosts several historical producers including the Buckhorn, Phoenix, and Beaverdell mines, which have collectively yielded more than 2 Moz gold, 6 Moz silver and 500 Mlb copper.
Arlington encompasses multiple mineral occurrences and at least four deposit styles across a more than 5 km strike length. Historic and recent surface work has confirmed high-grade mineralization with rock samples returning values up to 11.67 g/t gold, 211 g/t silver, and 3.22 percent copper. The 2025 exploration program, currently underway, includes a 3,000-metre drill campaign primarily targeting the Fresh Pots gold-silver anomaly – a large (2 km x 1 km) intrusion-related gold system delineated by multi-element soil geochemistry and magnetic lows.
Other high-priority targets include:
- Rona Porphyry Target: A copper-molybdenum-gold system with pyroxenite intrusive-hosted mineralization. Rock chip assays have returned >1 percent molybdenum, 0.6 g/t gold, and 32.4 g/t silver. The area is characterized by a large copper-nickel soil anomaly and widespread argillic alteration in adjacent sedimentary rocks.
- Arlington Polymetallic Veins: A structurally controlled vein system with documented historic workings. Highlights include Arlington South (11.67 g/t gold, 3.22 percent copper) and Arlington North (1.86 g/t gold, 1.07 percent copper), suggesting vertical metal zonation and potential for stacked vein systems.
- Skarn and Replacement Targets: Notably at the Bru and Arlington zones, analogous to Buckhorn and Phoenix, where gold-copper magnetite skarns produced over 1 Moz historically.
In early 2025, Equity Metals completed a property-wide airborne magnetic/radiometric survey and LiDAR mapping campaign to refine targeting. Soil and till geochemistry, IP surveying and mapping continue across the license area to delineate follow-up drill targets for 2026.

Appendix:
Silver Queen Mineral Resource Estimate (NI 43-101 Compliant, Dec. 1, 2022) (C$100 NSR cut-off)
- The current Mineral Resource Estimate was prepared by Garth Kirkham, P.Geo., of Kirkham Geosystems Ltd and Eugene Puritch, P. Eng., FEC, CET and Fred Brown, P, Geo. of P&E Mining Consultants Inc. (“P&E”), Independent Qualified Persons (“QP”), as defined by National instrument 43-101.
- All Mineral Resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum (“CIM”) definitions, as required under National Instrument 43-101 (“NI43-101”).
- Mineral Resources were constrained using continuous mining units demonstrating reasonable prospects of eventual economic extraction.
- Silver and Gold Equivalents were calculated from the interpolated block values using relative process recoveries and prices between the component metals and silver to determine a final AgEq and AuEq values.
- Silver and Gold Equivalents and NSR$/t values were calculated using average long-term prices of $20/oz silver, $1,700/oz gold, $3.50/lb copper, $0.95/lb lead and $1.45/lb zinc. All metal prices are stated in $USD. The C$100/tonne NSR cut-off grade value for the underground Mineral Resource was derived from mining costs of C$70/t, with process costs of C$20/t and G&A of C$10/t. Process recoveries used were Au 70%, Ag 80%, Cu 80%, Pb 81% and Zn 90%.
- Grade capping was performed on 1m composites for the No. 3 and NG-3 veins and whole vein composites for the Camp and Sveinson veins. For the No. 3 and NG-3 veins Inverse distance cubed (I/d3) was utilized for grade interpolation for Au and Ag and inverse distance squared (I/d2) was utilized for Cu, Pb and Zn. Inverse distance squared (I/d2) was used for all metals in the Camp and Sveinson veins.
- A bulk density of 3.56t/m3 was used for all tonnage calculations in the No. 3 and NG-3 veins. A variable density with a 3.15 average was used for the Camp and Sveinson veins.
- Mineral Resources are not Mineral Reserves until they have demonstrated economic viability. Mineral Resource Estimates do not account for a Mineral Resource’s mineability, selectivity, mining loss, or dilution.
- An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to add precisely.
