Brightstar Resources Ltd (ASX: BTR) (Brightstar) is pleased to announce the first results from RC infill drilling at the Lord Byron deposit, part of the 293koz Au Jasper Hills Gold Project. The program is targeting gold mineralisation within conceptual open pit shells beneath and between the existing open pits in order to increase confidence in the current resource.
HIGHLIGHTS
- The first assay results have been received from the ~8,000m Lord Byron infill drilling program at the Jasper Hills Gold Project
- The program forms part of an Reverse Circulation (RC) and Diamond (DD) drill-out at Jasper Hills, which was designed to infill the resource, improve the JORC classification and provide information for mine planning at the proposed Lord Byron Open Pit and Fish Underground mines announced in the Jasper Hills Scoping Study1
- Intercepts returned at Lord Byron, targeted to be mined via an open pit in 2025, include:
- LBRC24034:
- 32m @ 1.25 g/t Au from 53m
- LBRC24007:
- 24m @ 1.53 g/t Au from 53m
- LBRC24037:
- 19m @ 1.34 g/t Au from 73m
- LBRC24001:
- 14m @ 1.44 g/t Au from 77m
- LBRC24015:
- 12m @ 1.73 g/t Au from 177m
- LBRC24016:
- 15m @ 1.47 g/t Au from 178m
- LBRC24008:
- 5m @ 4.29 g/t Au from 92m
- LBRC24054:
- 9m @ 1.47 g/t Au from 29m, and
- 7m @ 3.36 g/t Au from 129m
- LBRC24032:
- 9m @ 2.05 g/t Au from 95m, and
- 4m @ 3.12 g/t Au from 71m
- LBRC24027:
- 5m @ 2.13 g/t Au from 52m
- LBRC24034:
- 54 RC holes and 2 DD holes have been drilled at Lord Byron, with assays pending for 25 RC holes, and an additional 9 DD drillholes remaining to drill at Lord Byron
- 30 RC holes and 8 DD holes have been completed at the Fish deposit, with assays to be reported when received and analysed. This drilling was completed to provide geological, metallurgical and geotechnical information to support near term mining operations
- The RC drilling rig has completed the program at Jasper Hills and has remobilised to Menzies to complete the infill drilling program at the Lady Shenton deposit
- A diamond drill rig is presently at Lord Byron completing a ~1,500m program with completion of all drilling at Jasper Hills targeted by early September 2024
Brightstar’s Managing Director, Alex Rovira, commented “These assays represent the first results from the recently acquired Linden Gold exploration package at the Jasper Hills Gold Project. The results are highly encouraging and align with grades and widths we expected from the existing 244koz Au mineral resource.
The increased confidence from this infill drilling will feed back into future resource estimates and ultimately help guide the near-term development of open pit mining operations at Lord Byron, as detailed in our recent scoping study1, which outlined the highly profitable production of 2.2Mt @ 1.6g/t for 115koz Au over three years.
Drilling continues with two drill rigs currently active at the Jasper Hills and Menzies Gold Projects, which will generate ongoing news flow in the coming months as assays are received and our geological understanding develops across our portfolio.”
TECHNICAL DISCUSSION
The RC drilling program at the Lord Byron totals 54 drill holes for ~8,000m of drilling, with assays pending for 25 holes.
The program aimed to infill the inferred portion of the resource within optimised open pit shells to a nominal 20m x 20m spacing in order to facilitate and upgrade of the resource to Indicated classification. This supports the ongoing definitive feasibility study and the assessment of a potential fast-tracked mine development.
An additional 1,500m diamond drilling program is presently underway at Lord Byron, which will provide structural, geotechnical, and metallurgical data for mine design and planning purposes.

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:

High-Grade Gold Discovery in First 8 Mile Drill Hole
- First RC hole at 8 Mile discovers high-grade gold and ends in mineralisation
- 8 Mile gold mineralisation extends 75m north of tenement boundary
The 8 Mile target is located within the Gidji JV Project (“Gidji” or “the Project”), approximately 15 kilometres north of Kalgoorlie and surrounded by multiple gold mining and processing operations, including Northern Star Resources Limited’s (“NST”) Kalgoorlie gold operations (Figure 1).
The 8 Mile Target is located immediately adjacent to NST’s “8-Mile Dam” gold deposit which, according to the most recent publicly available data, contains an estimated 7Mt @ 1.4g/t Au for 313,977 ounces1.
A limited number of fast-tracked results from the first RC hole, GJRC029, show a wide zone of gold mineralisation with a similar tenor to 8 Mile Dam (18m @ 0.94g/t Au from 480m including 1m @ 6.04g/t Au), approximately 75m north of the tenement boundary, and ended in mineralisation (3m @ 0.52g/t Au).
The Company is awaiting assay results from the remainder of the hole which are expected in 2-3 weeks.
Miramar’s Executive Chairman, Mr Allan Kelly, said the Company was excited to see gold mineralisation continuing onto Miramar’s ground for a significant distance.
“This is the first time we have discovered significant gold mineralisation on our side of the fence, even though the drill hole didn’t end up exactly where we planned it to. The flip side of this is that we have extended the strike of gold mineralisation for over 100m on to our tenements,” he said.
“We’ve also demonstrated a relationship between the IP anomalism and gold mineralisation, which makes the other IP anomalies we have outlined at Gidji even more prospective,” he said.
Figure 1. The Gidji JV Project and 8-Mile Dam in relation to Kalgoorlie and surrounding deposits.
GJRC029 aimed to test an Induced Polarisation (IP) anomaly on the tenement boundary interpreted to represent the sulphide-rich gold mineralisation seen at the neighbouring 8 Mile Dam Deposit.
GJRC029 was collared approximately 10m north of the tenement boundary and mirrored MPGD008, a diamond hole drilled down-dip approximately 40m south of the tenement boundary by KCGM in 2013 and which intersected significant gold mineralisation related to the 8 Mile mafic unit.
Unfortunately, GJRC029 deviated significantly from the planned azimuth and, as a result, by the time the hole was terminated at the target depth of 504m, the drill trace ended up approximately 75m north of the tenement boundary (Figure 2). Despite this, the hole intersected a thick section of the steep westerly- dipping and highly altered 8 Mile mafic unit with widespread sulphide mineralisation, including disseminated magnetite and coarse-grained arsenopyrite, pyrrhotite and chalcopyrite, similar to the 8 Mile Dam Deposit (Figure 3).
Based on visual logging of RC drill chips, handheld portable XRF results and magnetic susceptibility measurements, samples from the bottom 56m of the hole were sent for priority analysis by fire assay at Bureau Veritas in Kalgoorlie.
The results from these initial samples confirm the relationship between the gold mineralisation and sulphides, and a relationship between the best gold mineralisation and coincident magnetic anomalism and elevated Arsenic as measured by handheld portable XRF. The first results also confirm that the IP anomaly is associated with potentially significant gold mineralisation, whilst the significant deviation of GJRC029 away from the planned target increases the potential strike length of gold mineralisation on Miramar’s ground.
Significant results are listed in Table 1, with assay results from the remainder of the hole expected in coming weeks.
The initial RC drilling programme, which also tested two other IP targets, is nearing completion and results will be reported once received and compiled.
Once all assays are received, the Company will plan further RC and/or diamond drill holes including to test the dip and strike extent of the mineralisation intersected in GJRC029.
The Company advises that the WA Department of Mines, Petroleum and Exploration (DMPE) has extended the main Gidji JV tenement, E26/214, for a further five years, and will now expire in March 2030.

Pacgold
Investor Insight
Pacgold is one of Australia’s most compelling gold exploration opportunities, backed by a strong technical team, offering investors exposure to a large-scale, underexplored gold system with significant resource growth potential.
Overview
Pacgold (ASX:PGO) is an Australian gold exploration company focused on the systematic advancement of the Alice River gold project in Northern Queensland. The company is led by a technically driven and highly experienced team of geologists and mining professionals, with demonstrated success in exploration, resource development and capital markets.
Pacgold team on site at Alice River gold project
With a dominant land position in the region, Pacgold holds 377 sq km of exploration permits and eight mining leases across the prospective Alice River Fault Zone (ARFZ). This structure is interpreted as part of a large-scale intrusion-related gold system, with characteristics analogous to major global deposits such as Fort Knox (USA) and Hemi (Western Australia).
The company has validated its model through drilling success at the Central Zone, culminating in a maiden mineral resource of 474,000 oz of gold. This comprises both open pit and underground components, with resource grades averaging 1.2 grams per ton (g/t) gold, and zones open in all directions. Less than five percent of the strike length has been tested, and much of the prospective corridor is obscured by thin sand cover, highlighting strong potential for blind discoveries.
With extensive infrastructure already in place, including an airstrip, accommodation camp and road access within 100 km, Pacgold is positioned to rapidly scale exploration and accelerate resource growth. The 2025 campaign, which includes more than 10,000 metres of RC drilling and new IP surveys, aims to unlock the full regional potential of the ARFZ.
Company Highlights
- District-scale Discovery Potential: Pacgold controls more than 377 sq km of tenure and more than 30 km of strike length across the Alice River Fault Zone (ARFZ), a fertile, underexplored structural corridor in Northern Queensland.
- Maiden Resource: In May 2025, the company published a 474,000 oz gold mineral resource estimate (MRE), covering just five percent of the total strike, confirming high-grade mineralization and strong potential for expansion.
- Aggressive Exploration Strategy: More than 10,000 metres of RC drilling campaign is underway, complemented by air-core and diamond programs, aimed at growing the Central Zone resource and testing multiple regional targets.
- Attractive Valuation Entry: With a market capitalization of just ~AU$10 million and an EV of AU$8.5 million (as of Q1 2025), Pacgold provides a low-cost entry into a potentially Tier 1 gold system.
- Experienced Leadership: The board includes proven mine developers and discovery geologists with prior success at Chalice, AngloGold Ashanti, BHP and Sibanye-Stillwater.
Key Project
Alice River Gold Project
The Alice River gold project is a large-scale, greenstone-hosted gold system centred on the regional ARFZ, located in Northern Queensland. The project area comprises 377 sq km of contiguous tenure, including eight granted mining leases. Pacgold controls over 30 km of strike length along the ARFZ, a major crustal-scale structure that has only recently been systematically explored with modern techniques.
The deposit style is interpreted as an intrusion-related gold system, a highly attractive deposit type known for hosting long-life, large-tonnage gold mines. Examples include the Fort Knox gold mine in Alaska and the Hemi gold project in Western Australia. The Alice River system features sheeted quartz-sulfide veining, extensive sericite-altered zones, and strong IP chargeability responses coincident with surface gold anomalism.
Pacgold’s 2024 and 2025 drilling campaigns have focused on the Central Zone, which yielded the maiden MRE totaling 474,000 oz gold across both open pit and underground resources. The pit-constrained resource includes 10.6 Mt at 1.2 g/t gold (404,000 oz), with a further 1.5 Mt at 1.4 g/t gold (71,000 oz) defined for underground potential. High-grade zones remain open at depth and laterally, with drill spacing still relatively broad (~80 x 80 metres), leaving significant scope for resource expansion.
Beyond the Central Zone, the company has delineated multiple high-priority regional targets along the ARFZ. These include:
- White Lion: A compelling target with surface gold anomalism and a coincident IP chargeability anomaly. A gradient and dipole-dipole IP survey is being extended in Q2 2025, with drilling expected in Q4.
- Victoria and The Shadows: Emerging prospects to the south with limited historical drilling but strong geophysical responses.
- Posie and Southern Target Area: Additional areas along the southern ARFZ strike that exhibit strong structural preparation, geochemical responses and potential for concealed mineralization.
Drilling recommenced in April 2025, with RC drilling underway and air-core and diamond drilling scheduled through Q3 2025. The program aims to increase drill density in resource zones and test underexplored regional anomalies. Pacgold expects up to 15,000 metres of total drilling during the 2025 campaign, coupled with ongoing geophysical targeting, including IP and drone magnetics.
The project is fully permitted, with strong access and logistics, and is located in a low-risk jurisdiction with significant precedent for gold development. With limited historical exploration and clear mineralizing controls now defined, Alice River represents a transformative opportunity to uncover a Tier 1 discovery in an overlooked Australian belt.
