Brightstar Resources Limited (ASX:BTR) (Brightstar) is pleased to announce that the company’s resource base has exceeded 1 million ounces of gold with a significant upgrade to the Cork Tree Well deposit, located 30km north of Laverton in WA’s Goldfields region.
HIGHLIGHTS
- JORC 2012 Mineral Resource Estimate increased by 20% to 303koz at Cork Tree Well to deliver a combined JORC Resource base of 1.02Moz Au from Laverton & Menzies Gold Projects
- Importantly, the Mineral Resource upgrade represents a 65% increase to the Indicated ounces to 157koz @ 1.6g/t Au
- Two ~6,000m drill programs completed in late 2022 and Q1 20231 delivered the uplift in tonnages and ounces at a discovery cost of <A$30/oz
- Updated Cork Tree Well Mineral Resource Estimate completed by independent consultant ABGM Pty Ltd will feed into mining scoping studies underway
- The Mineral Resource Estimate has also highlighted that the model grade improves at depth and has confirmed the presence of a high-grade plunging shoot within the Cork Tree Well orebody
- This high-grade plunging shoot will continue to be drill tested in the upcoming RC drilling program, targeting depth extensions to the following best intersections within that zone:
- 10m @ 4.5g/t Au from 192m (BTRRC184)
- 22m @ 2.84g/t Au from 127m (BTRRC031)
- 26m @ 2.31g/t Au from 137m (BTRRC026)
- 29m @ 3.1g/t Au from 141m (SDR103602)
With over 11,000 metres of new drilling completed in late 2022 and early 2023 (refer Figure 2), the infill and extensional programs achieved the aim of identifying new mineralisation outside the previous JORC 2012 Mineral Resource Estimate and increasing confidence in the resource model. This is clearly shown by the Indicated material now accounting for over 50% of the Cork Tree Well Resource to provide a more robust base for mining scoping studies.
Brightstar’s Managing Director, Alex Rovira, commented“We are delighted to see the Cork Tree Well resource grow by over 20%, and more importantly grow our indicated component by 65% to over 3 million tonnes for over 157,000 ounces of gold.
Additionally, the updated Mineral Resource Estimate model has confirmed the presence of a number of higher grade plunging shoots that are open at depth and will be drill tested in upcoming campaigns.
These upgrades have seen Brightstar now control a +1 million ounce resource base with tangible growth shown in just one of our many resources at the Laverton and Menzies Gold Projects. We look forward to updating the market with further news on our drilling at our projects and our scoping study which are both presently underway”.
The updated mineral resource estimate is currently being used for exploration planning purposes in order to target areas that are open down plunge and to ensure sufficient drill density in zones currently classified as Inferred mineralisation to continue to grow the Indicated component of the MRE.
As shown in Tables 1 & 2, Brightstar’s resource at Cork Tree Well has expanded from 252koz to 303koz in less than twelve months, with indicated material increasing by over 1Mt or 62koz driven largely by the targeted resource drilling completed by Brightstar in 2022 and Q1 2023 with inferred material dropping slightly representing a positive conversion of inferred to indicated material which now represents over 50% of in-ground ounces.

ABGM Pty Ltd (ABGM), were engaged by Brightstar to undertake an update for the Mineral Resource Estimate for the Cork Tree Well Gold Deposit following completion of recent drill programs. The following text is a summary of their report issued to Brightstar.
Project Location
The Cork Tree Well Gold Deposit is on Brightstar’s wholly owned tenement M38/346, located 30 km north of Laverton. Access from Laverton is via the Great Central Road for 11km to the Bandya Road turn-off then 23km north on the Bandya Road.
Regional Geology
The Cork Tree Well gold deposit is located in the north Laverton Greenstone Belt on the southern extremity of the Duketon Greenstone Belt (DGB) in the north-eastern sector of the Eastern Goldfields Superterrane of the Yilgarn Craton. Abundant gold mineralisation in the Eastern Goldfields Superterrane has been attributed to the craton wide structural-metamorphic events that took place in the complex protracted structural evolution of the craton, between 2667Ma and 2615Ma.
The Laverton Greenstone Belt has the largest known gold endowment In the Eastern Goldfields Superterrane after the Kalgoorlie region. A narrow approximately 5km wide belt of attenuated north-south trending greenstone links the Duketon and Laverton belts.
The DGB is characterised by a deeply weathered, metamorphosed succession of Archaean mafic, ultramafic, and felsic volcanic rocks with associated volcanogenic sedimentary rocks and thin units of banded chert and banded iron formation. Late-stage high level acid to intermediate sills and dykes and associated small plutons intrude the sequence.

Overview
The price of gold is nearing a record high. Earlier this year, it topped $2,041.30 per ounce — the second-highest value in history. And there is every indication the previous metal's value will only continue to climb.
The reason is multifaceted. The world teeters on the brink of a severe recession. Amidst ballooning interest rates, bank failures and falling bond yields, demand for gold continues to rise.
This is to be expected, as bullion almost always becomes a hot commodity during times of economic uncertainty. 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 140 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. In fact, Brightstar has engaged experts for a scoping study to assess the refurbishment of its wholly owned onsite processing plant.
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 a number of years.
Brightstar also recently finalized a merger agreement with Kingwest Resources (ASX:KWR), under which Brightstar acquired 100 percent of the shares in Kingwest. From a strategic standpoint, this merger has allowed the two companies to consolidate their assets, resulting in combined JORC mineral resources of roughly 1 million ounces, all on granted mining leases.
The strategic merger also allows Brightstar to accelerate development and expansion of its existing mineral resources while also establishing the company as a potential near-term developer.
Brightstar's Laverton Gold Project assets are all centered on a 100%-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% of the Menzies Gold Project, a contiguous land package of granted mining leases over a strike length of roughly 15 kilometers along the Menzies Shear Zone and adjacent to the Goldfields Highway.
Company Highlights
- Brightstar Resources is an emerging ASX-listed mining and development company with more than one million ounces of gold resources and potential on-site processing infrastructure.
- The company has engaged experts to conduct a scoping study of its processing infrastructure with the goal of refurbishing and potentially expanding it.
- 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.
- Brightstar's mineral assets are situated across roughly 300 square kilometers of 100-percent-owned land in the Laverton Tectonic Zone. Together, they account for a current total JORC Resource of more than a million ounces.
- Brightstar’s Menzies Gold Project is a highly promising asset which has already undergone extensive historic mining and development. The Menzies Gold Project's total current resource estimate is 11.7 Mt @1.33 g/t gold for 505koz gold (40 percent measured and indicated; 60 percent inferred)
- 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. The 485 kilo-tons per annum carbon-in-leach plant is currently on care and maintenance. Brightstar is assessing a refurbishment and expansion strategy for the plant, building on a 2021 report from Cosmo Engineers.
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 including 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.
- Low Upfront Capital Cost: A 2021 report from Cosmo Engineers showed that fully refurbishing the plant to a 650-ktpa throughput represents a capital cost of roughly $5.5 million, including $1.9 million in owner's costs and a 30 percent contingency.
- Further Expansion: In June 2023, Brightstar announced that it has engaged a team of independent experts to conduct a scoping study which will assess refurbishment requirements and expansion opportunities.
- Close to Existing Assets: Brightstar's three major development projects — Cork Tree Well, Beta and Alpha — are all in close proximity to the plant.
Cork Tree Well
Cork Tree Well is a former 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 5,610 kilotons (kt) at 1.4 g/t for 252 koz of gold has increased by 20 percent to 303 koz, delivering a combined JORC Resource base of 1.02 million ounces gold from the Laverton and Menzies gold projects.
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. The JORC 2012 Mineral Resource Estimate increased by 20 percent to 303 koz delivering a combined JORC Resource base of 1.02 million ounces of gold and representing a 65-percent increase to the indicated ounces to 157 koz @ 1.6g/t gold. These results further provide a more robust base for mining scoping studies.
- 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.
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 prior to its merger with Brightstar, consists of a contiguous land package of a strike length in excess of 15 kilometers. All deposits are now 100-percent-owned by Brightstar and lie within granted mining leases.
Brightstar intends to leverage its processing infrastructure 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 have a 50/50 profit-sharing joint venture agreement to exploit the Selkirk deposit at Menzies. Under this agreement, Brightstar is responsible for capital costs, mining and haulage. The joint venture also has a toll treating agreement with St Barbara Limited (ASX:SBM) to process ore from Selkirk at Leonora.
- 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.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole MSRC012 (18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
