Timberline Resources Corporation (OTCQB:TLRS);(TSXV:TBR) ("Timberline" or the "Company") is pleased to report results from two more core holes from the 2021 drilling program at its 100%-controlled Eureka Project in Nevada. These are the final outstanding assays from the drill program, and they include one core hole in the Water Well Zone (WWZ) and the completed silver and multielement data from core hole BHSE-206C - totaling 861 meters of drilling.
The results from BHSE-192C confirm a significant zone of strong gold grades in the WWZ between drill holes BHSE-220C and BHSE-212C, which were reported during the first quarter (see Figure 1 and Company news releases dated February 24 and March 9, 2022). Highlights of the mineralization in BHSE-192C include:
- 24.4m at 3.85 grams per tonne (g/t) gold from 349.6 depth, including
- 4.6m at 8.35 g/t gold from 354.2m depth; and including
- 7.6m at 5.72 g/t gold from 364.8m depth.
The Company also received the complete analyses for silver (Ag) and other elements in drill hole BHSE-206C, from which the gold and partial multielement data were reported in a news release dated March 24, 2022. As previously reported, this hole included multiple intervals of anomalous gold, including 7.6m averaging 1.04 g/t and 86.9m of 0.16 g/t. However, the new analyses reveal that the drill hole is more mineralized in silver, lead (Pb), and zinc (Zn) than previously thought. One significant interval hosted by altered dolomite, breccias, and intrusive dikes included more than 202.7m that averaged 5.28 g/t Ag, including 56.4m averaging 9.69 g/t Ag, 0.17% Zn, and 0.11% Pb. This style of Ag-rich mineralization is believed by Timberline geologists to be older than the Carlin-type gold system, likely associated with Cretaceous-aged carbonate-replacement type deposits (CRD).
Patrick Highsmith, Timberline's President and CEO commented, "Drill hole BHSE-192C is an angled hole drilled into the Water Well Zone from the east. It is one of the first core holes to fill in between the high-grade results we reported last quarter. Our core drilling continues to confirm that the breccias at the base of the Dunderberg Shale are consistently mineralized over considerable thickness, but this hole also encountered strong gold grades in sheared and altered mudstones higher up in the Dunderberg. This result also extends the zone well to the east from previous drilling. Given the encouraging gold and silver associated with the IP anomaly in the Graben Zone farther east in BHSE-206C, we look forward to adding more core drilling in this area during the summer."
Figure 1 shows how the new results fit into the growing footprint of >3 g/t gold in the Water Well Zone. The long run of highly anomalous silver is also plotted along the trace of BHSE-206C. The IP anomaly occupies the graben between the Lookout-WWZ and Oswego gold occurrences, and it has yet to be tested at depth. Timberline expects to begin offsetting the new high-grade intercepts at the WWZ and near-surface gold at Oswego in June.

Geological Details and Interpretation
BHSE-192C was drilled on an azimuth of 300° at an initial inclination of -65°. The hole was designed to pass through an interpreted fault zone and penetrate the base of the east-dipping Dunderberg Shale. BHSE-206C was inclined -75° in a northeast direction (azimuth 050°) and designed to assess the upper reaches of the large IP chargeability anomaly identified in 2021.
Drillhole BHSE-192C was collared in the post-mineral volcanic rocks that occupy the Graben Zone east of the Lookout Mountain resource. The Cambrian-aged Windfall Formation was encountered at approximately 56m depth. The Windfall is a gray to orange (variably oxidized) thin-bedded limestone or silty-carbonate with frequent argillaceous layers or partings. In this area, the unit is highly faulted and brecciated, resulting in significant amounts of fault gouge and some core loss. The drillhole passed into the Dunderberg Shale at approximately 202m depth. The blue gray to greenish Dunderberg alternates between bedded and massive mudstone and is calcite-veined throughout. The upper portions of the unit exhibit frequent argillaceous partings and more reactive (carbonate-rich) bands. There is also ample evidence of faulting and brecciation. Fine-grained disseminated pyrite is first noted at approximately 210m depth, but there are several intervals of oxidation associated with faulting.
The gold zones occur near the base of the Dunderberg, but the highest-grade assays in the hole (13.75 g/t and 8.41 g/t Au) occur above the basal (carbonaceous and silicified) breccias that have characterized much of the WWZ. The upper zone of mineralization is associated with very fine-grained argillaceous mudstones that are sheared and brecciated, but not highly silicified or carbonaceous. The contact with the underlying Hamburg Dolomite is marked by approximately 8m of black, brecciated, silicified breccias containing sooty pyrite, and this interval is consistently rich in gold. Low levels of anomalous gold continue for at least 30m into the light-gray massive dolomite of the Hamburg, in which the hole was terminated.
BHSE-206C passed through a thick section of limestones - often highly fractured, brecciated, and variably oxidized - that are often anomalous in silver and arsenic in zones of fault breccia and gouge. The degree of brecciation and alteration increases with depth as the limestone passes into a chaotic interval of interbedded sanded dolomite (altered) and fine grained felsic intrusive rock with abundant pyrite, which locally exceeds 10%. The felsic dikes or sills begin at approximately 95m depth. The intrusive unit is light gray to green, fine-grained and has apparent granitic composition, termed an aplite. The aplite has been propylitically altered, evidenced in part by the presence of chlorite, calcite, and sericite.
Gold and silver are most abundant in the dolomite, particularly where it is highly fractured and brecciated. There is a good correlation between the presence of pyrite, gold, and silver, but the most intense silver mineralization is associated with a zone of iron oxide occurring between 270m and 321m depth. Arsenic is a well-known pathfinder element for Carlin-type gold, but it is also associated with the older silver-lead-zinc CRD mineralization in the Eureka District. Almost the entirety of this drill hole is enriched in arsenic, but local anomalies in elements such as bismuth, molybdenum and tungsten support the interpretation of nearby intrusive activity that may be driving the abundant silver (0.05 - 61.3 ppm), lead (2 - 7,000 ppm), and zinc (9 - >10,000 ppm) in the Graben Zone.
Pyrite increases as the drill hole passes into a light gray to pale green, fine-grained section of altered sediments, which may be affected by contact metamorphism from nearby intrusive rocks. The hole was terminated in an interval with abundant chlorite-sericite-pyrite veining and considerable evidence of faulting (brecciation and fault gouge).
Superimposed mineral systems are common and considered favorable in larger Carlin-type gold districts. The Ruby Hill - Archimedes Mine (i80 Gold Corp.), north of the Eureka Project, is an excellent example where millions of ounces of Carlin-type gold resources are reported to occur as overprinting earlier silver (gold) - lead - zinc mineralization. Similarly, at least three generations of mineralization are reported in the giant Carlin Trend District. The multiple generations of mineralization may have used the same fluid pathways in the rocks; plus, the earlier stage alteration and mineralization may have enhanced the receptiveness of the host rocks to the later Carlin-type fluids. Timberline is ramping up for its 2022 exploration program, which will target the Water Well Zone, the Oswego Target, and the huge IP anomaly that occupies the graben in between.
Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance
Cutting and sampling of core samples was directed by Timberline representatives. Personnel from Timberline or the drilling contractors transported the samples to Timberline's secure Eureka facility, from which the samples were picked up by personnel from ALS USA Inc. (ALS) for sample preparation in Elko, Nevada or Tucson, Arizona. Quality control was monitored by the insertion of numerous blind certified standard reference materials, field duplicates, and blanks into each sample shipment. Drill samples were assayed by ALS for gold by fire assay of a 30-gram charge with an AA or ICP-ES finish (ALS code Au-AA23). The overlimits for gold samples assaying above 10 g/t were determined by a 30-gram fire assay with gravimetric finish. Satisfactory results were achieved for all quality control samples related to the data reported herein. In addition, gold mineralized samples were submitted for multi-element analysis (33 elements) by four-acid digestion and ICP-ES determination (code ME-ICP61).

Augustus Acquires 1,345km2 Gold Exploration Project Near Leonora
- Augustus Minerals Limited( ASX: AUG) (“Augustus” or the “Company”) is pleased to announce that is has executed a binding share purchase agreement to acquire 100% of the issued capital in Music Well Gold Mines Pty Ltd, which holds the exploration licenses and applications comprising the Music Well Gold Project located 35km north of Leonora in the Leonora / Laverton Greenstone Belt of Western Australia.
- The large contiguous tenement package covers an area of 1,345 sq km in a region that hosts gold endowment of >12Moz1 gold and >450kozpa gold production2 within 50km of the project.
Neighbouring operating mines include:
Northern Star3 (ASX:NST)
- Thunderbox Mine3 (4.2M oz Au Resources) 20km to the west
- Wonder Underground (0.9Moz Au Resources3) <1km west
Genesis Minerals4 (ASX:GMD)
- Hub Project (0.7 Moz Au Resources) adjoining Music Well Project
Vault Minerals5 (ASX:VAU)
- Darlot Gold Mine (1.9 Moz Au Resources) is located 12km north
- King of the Hills mine (4.1 Moz Au Resources) 20km to the south west
- Extensive geophysics, gravity, soil sampling and rock chipping have already been completed with data validation and target prioritization underway
- Potential for gold discoveries from the dedicated and focused Augustus exploration team over the next 2 years.
Andrew Ford, GM Exploration commented
“The acquisition of such a large prospective gold exploration package in close proximity to operating mines owned by Northern Star, Genesis and Vault Minerals with +12M oz of resources and over 450kozpa gold production2 is a significant coup for Augustus (Figure 1).
“With the gold price now exceeding A$4,000/oz it provides Augustus Shareholders with significant exposure to future discovery in one of the greatest gold provinces in the world”.
Background
Comprising ten granted exploration licences covering an area of approximately 1,052km2 and two exploration licences in application covering an area of 293km2. The total tenement package is 1,345 sq km making the Project one of the largest exploration packages in the region.
Augustus believes that adding a gold focussed exploration project of this size provides optionality and complements its copper/base-metals/uranium focus at the Ti Tree Shear project in the Gascoyne.
Music Well Project
The Project is located within the Murrin Murrin domain, Kurnalpi Terrane of the Yilgarn Craton in the Leonora / Laverton Greenstone Belt of Western Australia.
The Yilgarn is a globally significant mineralised province for gold, nickel and aluminium, and also hosts major deposits of other minerals such as copper, zinc and iron along with other resources such as tantalum, lithium, vanadium, uranium and rare earth elements (“REEs”).
Figure 1: Project location, regional gold Mineral Resources and working processing plants. See Table 1 for source data for Mineral Resources of Gold Deposits in the Leonora-Laverton District).
MWGM initiated the consolidation of tenements and commenced field work, on ground exploration and targeting studies from November 2019. In the resulting 5-year period from November 2019 to November 2024 the Company has consolidated a tenement package of 1,345 sq kms and has identified priority targets for follow up exploration work for Air Core, RC and Diamond Drilling.
These high priority targets have been identified by using MWGMs “Three – Schema Gold Prospectivity Model” which incorporates and utilises classical structural mapping techniques, geochemistry such as Ultra Fine + (UFF) soil sampling, rock chip sampling and advanced geophysics. This multi-disciplinary approach to exploration utilising high-resolution airborne magnetics, gravity and radiometric data, including (UFF) soil sampling over + 1,052sq kms also includes the reinterpretation of the solid geology, structure and deformation history of the region to inform local interpretation of the geological framework and identification of the targets completed over a 5-year period within the Project area.
The geological studies, completed with the assistance of a group of technical specialists, including Southern Geoscience, Fathom Geophysics, Tower Geoscience, Geobase Australia, Daishat Geodictic Gravity Surveyors, Walter Witt Experience and GeoSpy Australia utilising high-resolution airborne magnetics, gravity and radiometric data.
The principal target types include gold in shear zones within granitoids and greenstones (analogous to the nearby Wonder Deeps Gold Mine (Northern Star) and intrusion-related gold systems potentially analogous to King of the Hills and Darlot Centenary mines located southwest and north of the Music Well Gold Project respectively. The Music Well Gold Project is considered to be prospective for gold, base metals and also for lithium, tantalum and REE, which will also be investigated.
The tenement area is characterised by a strongly deformed stratigraphy and intrusions and contains numerous predominantly west-northwest anastomosing subparallel shear zones providing links potentially to Wonder Deeps and Thunderbox gold mines (Northern Star) located to the west of the project area; and the Hub (Redcliffe) gold deposit located to the east (Genesis).
In addition, a series of north-northwest and north-northeast structures trend through the project area and structures of a similar orientation host many of the gold deposits in the Leonora / Laverton area.
There are numerous operating gold mines in the district including the Darlot Gold Mine (~12 km to the north), the King of the Hills Mine (~20 km to the west), the Leonora Gold Camp (~30km to the southwest), and the Thunderbox Gold Mine (~20 km to the west) (Figure 2).

Sarama Resources - Key Milestone in Cosmo Gold Project Acquisition
The acquisition now has approval from the shareholders of both Sarama and Cosmo and Sarama has received requisite approval and conditional approval from securities exchanges in Australia and Canada respectively. It is anticipated the Transaction will be completed in mid-November 2024.
The 580km² Cosmo Gold Project(2) covers the entirety of the Cosmo-Newbery Greenstone Belt and is located approximately 85km north-east of Laverton in a region known for its prolific gold endowment (refer Figure 1). As one of the last effectively unexplored greenstone belts in Western Australia, the Project presents a unique and compelling opportunity for the Company.
Highlights
- Sarama acquiring a majority interest in, and control of, Cosmo Gold Project in Western Australia
- Sarama acquiring an initial 80% interest(1) with ability to increase to 100% in the majority of the Project(1)
- 580km² landholding capturing +50km strike length in highly prospective gold producing region; 95km from both the world-class Gruyere Mine and Laverton gold district
- Project captures one of the last effectively unexplored greenstone belts in Western Australia; virtually no effective exploration undertaken for several decades
- Project is very well located being only a 4 hour drive from Kalgoorlie on predominantly paved roads
- All shareholders approvals for the Transaction secured
- Key conditions precedent satisfied and completion of transaction anticipated in mid-November 2024
- Meetings with Traditional Owners confirm support for Sarama’s involvement and its planned endeavours
- Soil geochemistry program underway to generate regional targets in unexplored areas
Sarama’s Executive Chairman, Andrew Dinning commented:
“We are pleased to have passed this major milestone and look forward to finalizing the acquisition of a majority interest in the Cosmo Gold Project in the coming weeks. Together with Cosmo, we have commenced our first soil geochemistry program which will continue over the next 6-8 weeks and feed into larger targeting efforts and work up of drill targets for the 2025 exploration season.”
Cosmo Newbery Project
The Project is comprised of 7 contiguous exploration tenements covering approximately 580km² in the Eastern Goldfields of Western Australia, approximately 85km north-east of Laverton and 95km west of the world-class Gruyere Gold Mine. The Project is readily accessible via the Great Central Road which services the Cosmo Newbery Community.
The Project captures one of the last unexplored greenstone belts in Western Australia and with a strike length of +50km, the Cosmo Newbery Belt represents a large and prospective system with gold first being discovered in the area in the 1890’s. Multiple historical gold workings are documented within the Project area and work undertaken to date, has identified multiple exploration targets for follow up.
Despite this significant prospectivity, the Project has seen virtually no modern exploration or drilling of merit due to a lack of land access persisting over a significant period. As a result, the Project has not benefited from the evolution of geochemical and geophysical techniques which now facilitate effective exploration in deeply weathered and complex regolith settings which is particularly pertinent given approximately 75% of the Project area is under cover.
Following the relatively recent securing of land access, the Project is now available for systematic and modern-day exploration programs to be conducted on a broad-scale. It is anticipated that future exploration programs will initially follow-up preliminary targets generated from regional soil sampling and limited reconnaissance drilling programs, a majority of which extended to approximately 5m below surface with a small percentage extending up to 30m below surface.

Brightstar Resources
Investor Insight
A gold-focused emerging gold producer with a clear pathway to production growth, Brightstar Resources presents a compelling investment case driven by its mining and development hubs strategy and a district-scale resource opportunity.
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 1,200 square kilometers in the Sandstone Greenstone Belt, 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 100 percent of the shares and options 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.
In August 2024, Brightstar entered into a scheme implementation deed to acquire 100 percent of Alto Metals (ASX:AME), which owns the Sandstone gold project located in East Murchison. The project has a current mineral resource of 1.05 Moz of gold at 1.5 g/t.
Brightstar also completed the acquisition of the gold rights at the Montague East gold project (MEGP) from Gateway Mining Limited (ASX:GML). The project is located 70 km from the Sandstone gold project. The acquisition adds a further 9.6 Mt @ 1.6 g/t gold for 0.5 Moz gold to Brightstar’s JORC Mineral Resource Estimate, giving the company a total mineral endowment of 38.3 Mt @ 1.6 g/t gold for 2.0 Moz gold.
The acquisition of the MGEP from Gateway Mining and 100 percent of Alto’s shares creates a third district-scale resource base for the company called the Sandstone Hub. Upon consolidation of the Laverton, Menzies and Sandstone hubs, Brightstar’s mineral resources would reach 3 Moz at 1.5g/t gold.
Subsequent to the deal with Alto Metals, Brightstar entered into a $4 million drill-for-equity agreement with Topdrill to aggressively advance the consolidated Sandstone gold project. The deal strengthens Brightstar's financial capacity to fulfill its multi-hub exploration and development strategy, which includes the Menzies, Laverton and Sandstone hubs.
Company Highlights
- Brightstar Resources is an ASX-listed mining and development company with more than 3 million ounces of gold resources and an on-site processing infrastructure across its project locations in Laverton, Menzies and Sandstone in Western Australia.
- 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.

- 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.
- 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.
- 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 has recently completed the acquisition of the gold rights at the Montague East gold project (MEGP) from Gateway Mining Limited (ASX:GML), and has entered into an agreement to acquire Alto Metals (ASX:AME) further creating the company’s third district-scale resource base known as the Sandstone Hub.
- Brightstar plans to continue generating shareholder value through a combination of development and strategic acquisitions along with some exploration.

Brightstar aims to fast-track the development timetable through:
- A focused, multi-rig infill drill out to take the inferred mineralisation into measured and indicated status to underpin mining studies and project advancement
- The application of Brightstar’s dedicated in-house geological and mining engineering team to retain crucial project IP and fast-tracked mining studies;
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
- A 60-person accommodation camp
- An airstrip at the 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.

Shallow, High-Grade Gold Mineralisation Intersected at Barimaia Gold Project
Key Points:
- Significant results received from the second phase of shallow Reverse Circulation (RC) drilling at the McNabs East Prospect at the Barimaia Gold Project in Western Australia, including:
- 2Gm @ 2.52g/t Au from 81m 24BARC083
- Including 1m @ 47.5g/t Au from 107m (visible gold present)
- 4m @ G.62g/t Au from 5Gm 24BARC102
- Including 1m @ 32.7g/t Au from 60m
- 25m @ 1.50g/t Au from 56m 24BARC087
- 5m @ 4.61g/t Au from 61m 24BARC104
- Including 1m @ 1G.6g/t Au from 64m
- 16m @ 1.23g/t Au from 5m 24BARC103
- 15m @ 1.24g/t Au from 30m 24BARC07G
- 2m @ 6.62g/t Au from 42m 24BARC0G7
- 7m @ 1.6Gg/t Au from 73m 24BARC07G
- 2Gm @ 2.52g/t Au from 81m 24BARC083
- Extensive zone of gold mineralisation now defined at McNabs East at shallow depths (typically <80m vertical) over a strike length of +1,000m and remains open along strike and untested at depth.
- The recent shallow drilling at McNabs East was completed on ~100m-spaced sections to continue the first-pass test of the Barimaia felsic intrusion.
- Primary mineralisation in the McNabs East area is associated with an interpreted granodiorite intrusion, strongly supporting the potential for Eridanus-style deposits at Barimaia.
- Diamond drilling planned for November to obtain structural and lithological data at McNabs East, which will be followed by extensional and in-fill RC drilling in the March 2025 Ǫuarter.
The RC drilling program was completed in September and October 2024 as the second phase of a larger, ongoing program to systematically test at shallow depths (typically < 80m vertical) the currently defined 2.5km strike extent of gold mineralisation at Barimaia.
Results from the program continue to confirm shallow, open pit potential, with coherent zones of gold mineralisation starting to be defined within an extensive gold system that remains untested at depth and remains open along strike.
Drilling completed on section 585,640E (see Figures 1 and 2) returned significant high-grade gold mineralisation in 24BARC083 (2Gm @ 2.52g/t Au from 81m) to the end of the hole (EOH) at 110m.
Visible gold was panned in the interval from 107m to 108m, which returned an intercept of 1m @ 47.5g/t Au.
Strong gold mineralisation was also returned from 24BARC087 (25m @ 1.50g/t Au from 56m) on section 585,550E (see Figures 1 and 3), adjacent to where a robust zone of gold mineralisation was intersected in drilling completed in August 2024 in 24BARC056 (21m @ 1.60g/t Au from 62m) and 24BARC057 (36m @ 0.85g/t Au from 50m). This interpreted flat-lying zone of gold mineralisation is over 80m wide on section.
Drilling completed on the eastern limit of the Phase 2 program on section 586,300E (see Figures 1 and 5) returned high-grade gold mineralisation in two separate zones, including 4m @ G.62g/t Au from 5Gm in 24BARC102 including 1m @ 32.7g/t Au from 60m; and 5m @ 4.61g/t Au from 61m in 24BARC104 including 1m @ 1G.6g/t Au from 64m. Importantly, no RC drilling has been completed east of this line along the interpreted strike of the mineralisation.
Management Comment
Commenting on the results, Ordell’s Managing Director, Michael Fowler, said:
“Our second drill program at Barimaia has delivered some great results, with wide zones of shallow gold mineralisation intersected within the targeted felsic intrusion host rock. Importantly, a number of high- grade gold results were returned from the program which are open at depth and along strike.
“This shows the potential of the mineralised system, which is beginning to take shape, pointing to significant future growth opportunities as our drilling programs advance.
“We have now completed over 5,000m since we listed on the ASX in July, with the results from this drilling showing clear potential for shallow open pits at Barimaia.
“Our next step is to complete a diamond drilling program in November to help confirm the orientation, lithologies and geometry of the significant mineralisation centred on section 585,550E. This drilling will be followed up by further extensional and in-fill drilling in the coming months.”

Ordell’s exploration at Barimaia is targeting new discoveries of a similar style to the Eridanus deposit, which forms part of Ramelius Resources’ (ASX: RMS) Mount Magnet gold mining operations (Figure 6).
Eridanus lies approximately 6km north-west of Barimaia and hosts a current Mineral Resource Estimate of 21Mt @ 1.7g/t Au for 1,200,000oz of contained gold1, with an additional +300,000 ounces of gold already mined from the open pit.
