Brightstar Resources Limited (ASX:BTR) (Brightstar) is pleased to confirm that resource definition and brownfields exploration drilling has recommenced at the Menzies Gold Project.
HIGHLIGHTS
- Drilling has commenced at the Menzies Gold project with over 5,000m of RC drilling planned across several locations
- Resource definition programs at Lady Irene & Aspacia, targeting extensions to previously announced high grade intercepts including:
- Lady Irene: 39.3m @ 4.27g/t Au from 159m (LIRD003)1
- Aspacia: Unmined development face samples ranging from 22.0g/t to 150.4g/t Au2
- Additional program planned to follow-up high grade hits in Lady Shenton-Lady Harriet ‘link zone’, including:
- 2m @ 31.7g/t from 41m (MZRC13070)3
- 6m @ 3.41g/t from 147m (KWR047)4
- Further drilling planned at Laverton Gold Project, with drilling crew to mobilise to Laverton after the Menzies program is completed in July
Brightstar’s Managing Director, Alex Rovira, commented“We are excited to commence drilling at several locations in our Menzies Gold Project. At Lady Irene, we are following up some amazing hits including a 39m
intercept, whilst at Aspacia we are looking to build confidence in our geological model which suggests the high- grade 30g/t Aspacia lode features repetitions both in the hangingwall and immediately to the south of Aspacia. Aspacia presents an opportunity to delineate high-grade, near surface ounces.
We are also following up some prospective geology and high-grade mineralisation between the Lady Shenton and
LadyHarrietminesinthe‘linkzone’, with three separate zones identified for follow up drilling.
The Mineral Resources within Menzies presents a significant opportunity for Brightstar to commercialise and assist funding larger-scale development endeavours underway to create a genuine WA gold producer with meaningful scale through the existing processing infrastructure and resource base.”

Technical Discussion
Brightstar is targeting mineralised structures in and around the mines of Lady Irene and Aspacia, located approximately 7km Northwest and 1.5km West of Menzies, respectively. Historic production was recorded from Lady Irene of 6,500oz grading 4.77g/t Au (open pit production to 2001) and Aspacia of 10,731oz grading 37.1g/t Au (underground production to 1982)5.
In particular, Brightstar is targeting resource additions to Lady Irene, with drilling focused on +4g/t Au high grade pods and targeting mineralisation intercepted in LIRD003 (39.3m @ 4.27g/t Au1) to gain further information on lode geometry including strike and plunge continuity beneath the Lady Irene South Pit. Whilst potential for underground mining strongly exists, it is envisaged that geological knowledge gained from this drill program will be utilised to target structural repetitions for future open pit resources along the Northern Trend, where Brightstar controls over 7km of essentially untested and fertile strike length between Lady Irene and Selkirk where transported cover hampered early explorers.

Brightstar Resources
Overview
The price of gold stays strong. In April 2024, the yellow metal’s price passed US$2,400 per ounce for the first time. The reason is multifaceted. The world teeters on the brink of a severe recession while some markets attribute the increase to safe haven rush. Amidst ballooning interest rates, bank failures and falling bond yields, demand for gold continues to rise. At this precise moment, gold is simultaneously an excellent portfolio diversifier and a compelling hedge against ongoing inflation — particularly if one invests in the right company.
Brightstar Resources (ASX:BTR) aims to be that company. An emerging mining and development company, Brightstar occupies a strategic land position of roughly 300 square kilometers in the Laverton Tectonic Belt and 80 square kilometers of the Menzies Shear Zone.
The company also owns an existing processing facility that can potentially provide tremendous shareholder value in a low-capital cost restart scenario.
That plant, once fully refurbished and operational, could prove a key differentiator for the company, enabling fast gold production at a low capital cost. This is especially noteworthy given that many other gold companies trading on the ASX are largely focused on greenfield exploration and development. Even once those companies discover a promising resource, mining and processing facilities would still need to be built, undertakings which can incur significant upfront capital costs and take several years.
Brightstar's Laverton gold assets are all centered on a 100 percent-owned 300-square-kilometer tenure in the Laverton Tectonic Zone and all within 70 kilometers of the Laverton Processing Plant. Additionally, all resources within this zone are open along strike and at depth. Only minor drilling programs have been conducted in recent years, paving the way for significant exploration upside with the potential for further regional and greenfields discoveries.
Brightstar also owns 100 percent of the Menzies Gold Project, a contiguous land package of granted mining leases over a strike length of roughly 20 kilometers along the Menzies Shear Zone and adjacent to the Goldfields Highway.
In 2023 and 2024, the company announced a mineral resource upgrade to the Cork Tree Well deposit (Laverton gold project) and also delivered two maiden mineral resource estimates at the Link Zone and Aspacia deposits (Menzies gold project). This has grown the total group MRE by approximately 150 koz gold through organic exploration.
The company has also acquired a relevant interest in 96.75 percent shares and 96.81 percent optionshares and 96.81 percent option of Linden Gold Alliance, a gold producer, developer and explorer with existing mineral resources of 350 koz @ 2.1 g/t gold near Brightstar in the Laverton district. Brightstar’s MRE has reached 1.1 Moz gold across the Menzies and Laverton projects, with an additional 0.35 Moz gold in resources added after the successful acquisition of Linden Gold Alliance. Brightstar has commenced the compulsory acquisition process for the remaining Linden shares and options in respect of which it has not received acceptances under the agreemnt.Company Highlights
- Brightstar Resources is an ASX-listed mining and development company with more than one million ounces of gold resources and an on-site processing infrastructure.
- Brightstar's mineral assets are situated across roughly 300 square kilometers of 100-percent-owned land in the Laverton Tectonic Zone and ~80 square kilometers in the high-grade Menzies Shear Zone.
- The Laverton Gold project has a mineral resource of 9.7 Mt @ 1.6g/t gold for 511 koz gold and the Menzies gold project has 13.8Mt @ 1.3g/t gold for 595 koz gold. This is a total combined existing mineral resource of 23 Mt @ 1.5 g/t gold for 1.1 Moz of gold
- In 2023, the company completed a scoping study into the development of its Menzies and Laverton gold projects and the refurbishment and restart of its processing plant in Laverton.
- The scoping study produced robust operating outcomes and compelling financial outputs, including:
- 322 koz of gold recovered over eight years (40 koz per annum)
- Net present value of AU$103 million (using a gold price of AU$2,900/oz)
- Internal rate of return of 79 percent
- Pre-production capital requirements of AU$22 million
- All-in sustaining costs of A$2,041/oz
- Once refurbished, this infrastructure will allow Brightstar to fill a growing investment void for near-term gold developers in Western Australia, producing large quantities of gold at low capital cost.
- In 2023 and 2024, Brightstar completed a small-scale mining joint venture with BML Ventures which involved a 50/50 profit-sharing agreement to exploit the Selkirk deposit at Menzies. In April 2024, Brightstar announced that this joint venture delivered a net profit to Brightstar of $6.5 million.
- In June 2024, the company successfully acquired all of the issued ordinary shares and options in Linden Gold Alliance, a gold producer, developer and explorer with existing mineral resources of 350 koz @ 2.1 g/t gold near Brightstar in the Laverton district.
- Linden is currently a gold producer, mining 15-20 koz pa from its high-grade underground Second Fortune Mine south of Laverton.
- Brightstar’s total MRE across the Menzies and Laverton gold projects increased to 1.45 Moz gold after acquiring Linden. All of the mineral resources are located on granted mining licenses.
- As part of the merger with Linden Gold, Brightstar released a scoping study into Linden’s development-ready Jasper Hills gold project, which delivered key metrics including:
- 140 koz mined over 3.75 years (35 koz pa)
- Net present value of AU$99 million
- Internal rate of return of 736 percent
- Pre-production capital requirements of $12 million
- All-in sustaining costs of AU$1,972/oz
- Jasper Hills is located just 50 km SE of Brightstar’s processing plant in the Laverton gold project
- Brightstar plans to continue generating shareholder value through a combination of development and strategic acquisitions along with some exploration.
Key Projects
Brightstar Processing Facility
Situated close to Brightstar's existing mineral assets at Laverton, the Brightstar Processing Plant provides the company with a considerable operational head start over its peers.
Highlights:
- Extensive Infrastructure: Current facilities at the plant include two ball mills, a power station and gravity and elution circuits. Other infrastructure includes:
- A tailings storage dam
- An on-site process water pond
- An operational 60-person accommodation camp
- An airstrip at the nearby Cork Tree Well Project
- Vehicles and equipment include a forklift, bobcat, two loaders, multiple light vehicles and a 30-tonne crane.
- A Leg Up Over Competitors: The presence of pre-existing processing infrastructure represents significant time savings compared to greenfields development. Brightstar had an independent valuation completed which valued the processing plant at AU$60 million in replacement value.
- Low Upfront Capital Cost: As part of the scoping study released in September 2023, GR Engineering estimated a capital cost requirement to refurbish and expand the milling capacity would cost just AU$18.5 million.
- Close to Existing Assets: Brightstar's major development projects — Cork Tree Well, Jasper Hills, Beta and Alpha — are all close to the plant.

Cork Tree Well
Cork Tree Well is a formerly operating mine, producing 45 koz of gold over its lifespan. Located roughly 35 kilometers north of Laverton on Bandya Station Road, the project’s JORC 2012-compliant mineral resource of 6.4 Mt at 1.4 g/t for 303 koz of gold.
Highlights:
- Promising Drilling Results: Two 6,000-meter drill programs were completed in late 2022, and in the first quarter of 2023 delivered an uplift in tonnages and ounces at a discovery cost of AU$30 per ounce. In 2023 the JORC 2012 Mineral Resource Estimate increased by 20 percent to 303 koz, representing a 65-percent increase to the indicated ounces to 157 koz @ 1.6 g/t gold.
- Upcoming Feasibility Studies: The drilling program will underpin several feasibility studies that Brightstar intends to conduct later this year. At present, Brightstar has defined a resource envelope over a strike length of approximately 1 kilometer and down to 200 meters.
- Area Geology: The Cork Tree deposit is situated along the western limb of the Erlistoun synclical structure, a sequence which includes mafic volcanic lavas, tuffs and tuffaceous sediments alongside minor interflow graphitic shales and banded iron formation. The mine itself consists of chlorite schist-altered high-magnesium basalt footwalls overlain by graphitic shales containing banded iron and chert beds. Gold mineralization is contained within sediments intruded by concordant porphyry sills spanning the length of the mineralized zone.
- High-grade Assays from the 2024 Drill Program: First round of assay results from 20 diamond drill holes at Cork Tree Well were extremely positive, with intercepts returned including 34.4 metres @ 7.94 g/t gold from 43.5 metres (CTWMET004) and 27.6 metres @ 17.8 g/t gold from 51 metres (CTWMET003).
Second Fortune Gold Mine
Second Fortune is an operating underground gold mine owned and run by Linden Gold, which is the subject of an off-market takeover by Brightstar announced in March 2024. Second Fortune has produced +14,000oz gold in FY24 year to date and is run under an ‘owner operator’ model.
Second Fortune has a high-grade MRE of 165kt @ 10.9 g/t gold for 58 koz. Limited modern and systematic exploration has occurred across the ~20km of strike length of prospective geology at Second Fortune. This presents a superb opportunity to leverage existing team, camp & related infrastructure to rapidly assess targets and conduct efficient drilling programs to further grow the MRE and extend the mine life at Second Fortune.
Menzies Gold Project
Situated 130 kilometers north of the globally significant Kalgoorlie gold deposit, Menzies represents one of Western Australia's leading historic gold fields. The project, fully owned and operated by Kingwest before its merger with Brightstar, consists of a contiguous land package of a strike length above 20 kilometers. All deposits are now 100 percent owned by Brightstar and lie within granted mining leases.
Brightstar intends to leverage existing processing infrastructure in the district to monetise the high-grade open pit ounces produced by this mine.
Highlights:
- Significant Historical Production: Menzies has hosted multiple historically mined high-grade gold deposits which together produced a total of over 800,000 ounces at 19 g/t gold. This includes 643,000 oz @ 22.5 g/t gold from underground.
- Profit Sharing: Brightstar and BLM Ventures had a 50/50 profit-sharing joint venture agreement to exploit the Selkirk deposit at Menzies. In March 2024, Brighstar announced the successful completion of all the ore processing from the Selkirk JV, with a total of 430.7 kg of gold doré poured which netted Brightstar $6.5 million as part of its profit share.
- Area Geology: The Menzies Gold Project is hosted along the Menzies Shear Zone in the western margin of the Menzies greenstone belt. It displays a geologic setting similar to the Sand Queen Gold Mine at Comet Vale.
LAVERTON GOLD PROJECT – OTHER RESOURCES
Beta
Located immediately adjacent to the Brightstar Plant, the Beta Project includes a 60-person camp. It contains a combined JORC 2012-compliant mineral resource of 1,882 kt at 1.7 g/t for 102 koz of gold. The deposit occurs along the Eastern Margin of the Laverton Tectonic Zone, notable for hosting multiple major gold occurrences including Granny Smith, Keringal, Red October and Sunrise Dam.
Alpha
Hosting a combined JORC 2012-compliant mineral resource of 1,452 gold at 2.3 g/t for 106 koz, the Alpha Project. Future exploration programs and feasibility studies will seek to potentially capitalize on Alpha's close proximity to Beta.

Maiden Mukinbudin Quartz Processing Testwork Achieves Premium HPQ Product
Highlights
- Exceptional Processing Testwork results received from North Carolina State University’s Mineral Research Laboratory (NCSU-MRL), an industry leading independent High Purity Ǫuartz lab.
- Ǫuartz sample T1-C, a maiden sample from the Mukinbudin Project, achieved >99.991% SiO2 from a simple processing flow sheet that included attrition, flotation and magnetic separation treatment, opening opportunities for early stage offtake.
- All samples sent to NCSU-MRL, from both Pippingarra and Mukinbudin demonstrated outstanding purity levels, confirming the exciting potential of IND’s quartz deposits and their suitability for high-end applications.
- In parallel with the numerous ongoing offtake discussions and ongoing end customer testing, IND now plans to undertake further comprehensive independent testwork at leading industrial minerals consultancy ANZAPLAN in Germany to further assist in finalising product offtake.
IND is exploring for High Purity Ǫuartz (“HPǪ”) at several of its projects in Western Australia, and the testwork was completed on samples from IND’s Pippingarra Ǫuarry Project and Mukinbudin Ǫuartz/Feldspar Project.
Jeff Sweet, Managing Director of Industrial Minerals, commented:
“We are extremely encouraged by achieving +99.99% SiO2 purity through to the acid leaching stage of our process testwork. These results are incredibly promising for our HPǪ production. With calcination and hot chlorination stages yet to be tested, we anticipate even greater purity levels can be achieved. This progress underscores our confidence in achieving premium quality in our final product.
“The Mukinbudin quartz was purified to 99.991% SiO2 through magnetic separation and flotation process work alone. This simple flowsheet will allow IND to pursue early-stage offtake opportunities into a broader range of HPǪ applications.
“Given the large price differential at the premium end of the HPǪ market as illustrated in Figure 1, IND’s ultimate goal is to now test the maximum purity level achievable across the Company’s quartz projects with the aim to be a recognised long term supplier of quality HPǪ products.”

Jeffreys Find Gold Mine Toll Milling of 150,000 Tonnes Commenced, Second 2024 Campaign
HIGHLIGHTS
- Processing of 150,000 tonnes commenced at Greenfields Mill.
- 75,600 tonnes on ROM Pad at Greenfields as of 23 July 2024.
- Second campaign expected to finish early September 2024.
- On target to process 300,000 tonnes at Greenfields Mill in 2024/2025.
- BML expects to mine well in excess of 300,000 tonnes in 2024/2025.
- First cash distributions to Auric this quarter.
MANAGEMENT COMMENT
Managing Director, Mark English, said: “We have the good fortune of pouring gold just as the price firms. It happened last year when the price went to $3,000 an ounce, this year it’s around $3,600 an ounce.
“The ever increasing gold price will result in Auric and our joint venture partner generating cash surpluses well in excess of what we had budgeted and anticipated.
“150,000 tonnes is a sizeable parcel of ore for this campaign. While it will take six weeks or so to mill, we expect it to generate well in excess of $25 million through gold sales for the joint venture.
“The mill contract is to process 300,000 tonnes in 2024. This 150,000 tonnes parcel will be the largest for Stage 2 of mining of Jeffreys Find. That leaves an additional 120,000 tonnes for milling at Greenfields towards the end of 2024.
“Jeffreys Find will be a substantial cash producer for Auric in 2024. We are on target to receive our first distribution within about a month.” said Mr English.

Viani - Low Sulphidation Epithermal Gold Project License Renewed
Highlights
- MRD notified Alice Queen on Friday 19 July 2024 via email that its Viani license (SPL1513) has been renewed for a further three years with effect from Wednesday 3 July 2024.
- Viani, located on the Pacific Rim of Fire on Vanua Levu in Fiji, covers an area greater than 200km2 and is largely under explored (see Figures 1 and 2).
- The Dakuniba prospect within Viani has been previously sampled where epithermal gold mineralisation has been recorded in outcrop samples over a >3km strike length.
- Multiple epithermal veins within the Dakuniba prospect area, 5km by 1.5km surface gold-in- soil geochemical anomaly - the footprint of the epithermal mineralisation is comparable to other economically productive gold epithermal deposits globally.
- Previous drilling by Japanese International Cooperation Agency (JICA) in 1997 focused on a small, shallow part of the overall system and intersected high grade epithermal gold mineralisation.
- (Hole MJFV-5 (see Figure 3) over 6 vein zones at 50 to 100m below surface with best results, 0.6m @ 27.6 g/t Au & 900 g/t Ag and 0.4m @ 11.7 g/t Au1 and remains open in all directions.
- The JICA drilling was limited to only 600m of strike-length of the 5km long gold-in-soil anomaly (>10ppb Au) supported by epithermal geochemistry i.e., Ag and As.
- Based on discovery knowledge from epithermal systems worldwide, it is apparent the historical drilling was an inadequate test of the Viani gold system.
Alice Queen’s Managing Director, Andrew Buxton said,
We are delighted the SPL1513 license has been renewed for a further three years and look forward to continuing to work alongside the Fiji Mineral Resources Department as we commence our next phase of exploration activities. The Viani Gold Project is a tremendous prospect which has demonstrated it has the potential to become a significant epithermal system. With the license now renewed and the Company fully funded for its Fiji exploration plans, Alice Queen will continue the systematic exploration of the Viani Gold Project with the Company having commenced planning for its upcoming exploration programs.
Viani
Figure 1. Fiji Project locations.
Figure 2. Location of the Dakuniba Prospect in relation with SPL1513.
The Viani project (SPL1513) covers an area greater than 200km2 on the Caukadrove Peninsula on the Pacific Rim of Fire, Vanua Levu, Fiji. It is well serviced from Savu Savu on Vanua Levu and is highly prospective for a high-grade LSE gold system (see ASX releases 2 December 2022, “VIANI UPDATE” and 6 March 2023, “ALICE QUEEN UPGRADES VIANI EPITHERMAL PROJECT”.
Following a renewal process for Viani (SPL1513) which the Company commenced earlier this year (including as announced in the Quarterly Activities Report released to ASX on 23 April 2024), MRD notified Alice Queen on Friday 19 July 2024 that the license had been renewed with effect from Wednesday 3 July 2024 for a further three years. The renewed license includes typical terms for a license of this nature, including minimum work program and expenditure requirements.
Whilst the greater project area remains under explored, extensive sampling, trenching and (historic) limited drilling of the Dakuniba prospect area has been previously completed.
Previous drilling by JICA in 1997 returned multiple epithermal gold intersections in shallow drilling. Hole MJFV-5 (see Figure 2) intersected 6 vein zones at 50 to 100m below surface (best results include 0.6m @ 27.6ppm Au & 900ppm Ag, 0.4m @ 11.7ppm Au & 4.3ppm Ag)1. The JICA drilling was limited to only 600m of strike-length of the 5km long gold-in-soil anomaly (>10ppb Au) supported by epithermal geochemistry i.e., Ag and As.
Further details in relation to upcoming exploration plans at Viani will be announced in due course.
