Ultra-potassic stockwork outcrop identifies a new Central Porphyry
Altair Minerals Limited (ASX: ALR) (‘the Company’ or ‘Altair’) is pleased to announce preliminary findings following a site visit where the Company has identified a significant outcrop of stockwork system at Central Porphyry. Outcropping quartzite, magnetite and secondary biotite veined porphyry stockwork which is part of a new separate Central Porphyry – 3km Southwest of the high-grade Irka NE Porphyry2.
Key Highlights:
- Identification of new Central Porphyry | Venatica West a Porphyry Cluster
Site visit has discovered a significant outcrop of leached porphyry stockwork and ultra-potassic vein system which identifies a Central Porphyry intrusive part of a cluster system at Venatica West. Typical alteration and veining present within Bornite-Gold rich Copper Porphyry systems. - Extremely dense veining and stockwork | Multi-stage Mineralisation
Stockwork of A-type quartz, magnetite and secondary biotite on Central Porphyry is the densest identified to date across Venatica West, suggesting significant hydrothermal activity, overlapping events, fracturing and multi-stage mineralisation at Central Porphyry, ideal for copper enrichment. - Small portion of a much larger system | Central Porphyry Remains Open
Identification of Central Porphyry is an outstanding outcome, due to only a portion of the potassic stockwork zone outcropping, which could’ve easily been missed. Ultra-potassic alteration with dense stockwork as seen within this outcrop, generally tends to expand kilometres, with remaining footprint of alteration sitting under soil cover. Further fieldwork can identify full extent of this Central Porphyry. - Potential for regional Porphyry system | SW – NE Regional Porphyry System
Preliminary fieldwork analysis on-going, with already a new Central Porphyry system being identified within virgin grounds at Venatica West, sitting ~3km Southwest of the high-grade Irka NE Porphyry and ~2km Northeast of the Irka SW Porphyry-Skarn system2. Suggestive of a regional SW to NE trending porphyry cluster, filling the intersection of two district faults. - Community Engagement Commenced | Early Community Approval
Early engagement has commenced with the local community, with multiple local members showing support for on-going exploration works. Altair’s exploration team has also met with the President of the Community with very positive preliminary discussions. Altair has received initial community approval for exploration works with intention of putting forward long-term proposal of work programs, community incentive programs, project scheduling and local training.
Discovery of New Central Porphyry at Venatica West
The Central Porphyry is located on the Irka permit, situated ~3km southwest of the high-grade Irka NE Porphyry target and is a new intrusion system identified within Venatica West during initial site visit. The upper zone of a new Central Porphyry has been identified through outcrop which consists of leached ultra-potassic stockwork of quartz, magnetite and secondary biotite dense veining, and surrounded by phyllic alteration halo and hosted within overprinted argillic alteration.
The ultra-potassic alteration suggests Altair is standing above the core of the Central Porphyry. The overprinting of strong argillic alteration has occurred from later stage hydrothermal fluids which has replaced the feldspars with clay material while maintaining the stockwork veining – suggesting a multi- stage mineralisation event which can significantly enrich the grades of copper sulphide and hypogene zone below. This leached stockwork from late-stage argillic alteration indicates the copper has been remobilized and disseminated into structurally favourable zones below, with potential to enhance grades within the contacts and breccia’s at the core of the Central Porphyry.
The ultra-potassic zone generally sits right above the core of a Porphyry intrusion and in the case of the Central Porphyry, it is the densest set of stockwork, and veinlets discovered so far at Venatica West, with high alteration suggesting this area is the key part of hydrothermal activity and potentially the feeder to multiple other Porphyry systems.
The presence of dense secondary biotite veining on altered ultra-potassic outcrop not only indicates the presence of a new Porphyry system sitting below but also is an essential element for developing a large-scale Porphyry deposit within this particular belt.
Within other billion-tonne deposits proximal to Venatica, the presence of secondary biotite into the plays a key role in developing “scale” as its presence within porphyry stock and outwards into diorite host rock, tends to allow substitution of Fe2+ and Mg2+ with Cu2+, which can extend the copper mineral deposit footprint by a further ~500m radius in each direction from the main Porphyry core.1

Company Highlights
- Altair Minerals’ two world-class projects - Venatica in Peru and Olympic Domain in Australia - are located in globally significant mining districts, targeting Tier-1 copper and gold deposits.
- Venatica Project is a 337 sq km exploration project in the world-famous Andahuaylas-Yauri Porphyry Belt, featuring extensive copper-gold porphyry and skarn mineralization with proven high-grade historical production.
- The Olympic Domain project, located in South Australia’s Gawler Craton, is an 831 sq km IOCG project adjacent to BHP’s Oak Dam deposit (1.34 Bt @ 0.66 percent copper and 0.33 g/t gold) and boasts major analogous geophysical anomalies just 5 km from the Oak Dam deposit, indicative of significant mineralization.
- Historic sampling and exploration work was conducted at Venatica by INMET prior to its subsequent take over First Quantum for C$5.1 billion. The historic work has shown two major porphyry targets of 6 sq kmand 4 sq km, respectively, which have demonstrated abundant copper mineralisation at surface.
- Historic sampling at Venatica covers a small portion of the overall target, leaving substantial scope to expand its target size which remains open in all directions, these samples include:
- 7.0 percent copper and 33 g/t silver (sample 2254)
- 5.7 percent copper and 43 g/t silver (sample 4807)
- 4.8 percent copper and 32 g/t silver (sample 15245)
- 6.5 percent copper and 0.52 g/t gold (sample 4803)
- 4.8 percent copper and 0.40 g/t gold (sample 4801)
- Advanced geophysical techniques, modernized modelling has refined drill at Olympic Domain which shows previous impressive holes have narrowly missed the true core of the IOCG body, which shows a target size larger than the adjacent Oak Dam deposit owned by BHP.
- Altair’s boasts a first class and leading technical exploration team, who have cumulatively contributed to 11.4 Mt of copper and 26 Moz of gold discoveries in the past two decades.
Key Projects
Venatica Project (Flagship) – Peru
Location of Venatica Project, sitting along the Las Bambas trend and on key contact of Andahuaylas-Yauri Intrusive Batholith which is the main structural feature facilitating Tier-1 Copper deposits on the belt.
The Venatica Project, Altair Minerals' flagship asset, is strategically situated in Peru’s Andahuaylas-Yauri Porphyry Belt, a globally significant copper-producing region. The project is neighboring and sitting along strike Tier-1 mines, including Las Bambas, Antapaccay and Haquira, collectively establishing the area as one of the world’s premier porphyry copper districts. These mines contribute significantly to Peru’s copper output, underscoring the region’s importance in the global supply chain. Spanning approximately 337 sq km, Venatica’s land package is strategically positioned along the northern extension of the batholith intrusion contact zone, a geological anomaly known for hosting large-scale copper deposits with no modern exploration. Altair holds a first-mover advantage, being the first company to test the extension of this trend which has without failure made Tier-1 discoveries every ~60 km. The project’s geology is characterized by a combination of porphyry and skarn mineralization, which underpins its exceptional exploration potential.
Within Venatica West, the Irka NE target, a copper-molybdenum-gold porphyry system with a lateral footprint of 4 sq km, has yielded exceptional surface sampling results, including reported historic grades of up to 9.5 percent copper, 4.6 grams per ton (g/t) gold, and 160 g/t silver.
Additionally, a porphyry-skarn target covering a 6 sq km footprint within the contact aureole of the Andahuaylas-Yauri Batholith has historically been mined via small-scale operations, with exploited grades of 4 percent copper at the base of 10 meter pits – and remaining open at depth. These targets align with regional structural controls, consistent with the characteristics of nearby Tier-1 deposits.

Historic exploration has been conducted highlighting Venatica’s tremendous potential, including geophysical surveys which have delineated two primary anomalies with strong structural controls, providing clear focus areas for future drilling. Over 140 stream sediment and rock chip samples have confirmed high-grade copper mineralization, alongside historical artisanal mining efforts, including shallow pits and shafts, that have validated the presence of high-grade copper near the surface, further supporting the project’s prospectivity.
Within Venatica East, major sets of stream anomalies have been identified over 5 times the background levels for Copper, delineating over 17km strike of anomalous zones for maiden exploration.

The stream anomalies present at Venatica East are analogous to the Haquira discovery (1.4 Bt @ 0.46 percent copper, taken over by First Quantum for C$650 million in 2010) – sitting along strike Venatica sharing the same trend, host rock and structural controls. Haquira was first identified through similar stream anomalies which, like Venatica, recorded over 5 times background levels for copper.

The project benefits from excellent infrastructure and logistics. Venatica is accessible via established road networks and is in close proximity to major mining hubs, ensuring cost-effective exploration and potential future development. The region is well-connected to the electrical grid, and nearby towns offer access to a skilled mining workforce familiar with the operating conditions in the region.
Venatica’s strategic location within one of the world’s most productive porphyry belts further adds to the attractiveness of the project. Neighboring operations, such as Las Bambas (1.87 Bt @ 0.62 percent copper) and Haquira (1.39 Bt @ 0.48 percent copper), highlight the region’s capacity to host massive copper deposits. Altair’s project lies along the same structural corridor, significantly increasing the likelihood of discovering a Tier-1 deposit.
Altair has an aggressive exploration program planned to advance Venatica toward discovery. A drilling campaign is scheduled for Q2 2025, targeting the vertical extensions of the identified porphyry and skarn systems. The drill campaign will be complemented by advanced geophysical and geochemical mapping to refine structural interpretations and geological models. Resource delineation efforts will focus on defining both the lateral and vertical extent of mineralized zones, with the ultimate goal of confirming Venatica’s Tier-1 potential.
Olympic Domain Project – South Australia
Olympic Domain tenements
The Olympic Domain project, located in South Australia’s Gawler Craton, is one of the most promising IOCG (iron oxide copper gold) exploration projects globally. This region hosts renowned assets such as BHP’s Oak Dam and Carrapateena, and the world-class Olympic Dam deposit, underscoring its exceptional mineral potential. With an extensive land package spanning ~831 sq km, the project comprises three key prospects: Horse Well, Pernatty C and Lake Torrens, each with unique geological attributes indicative of Tier-1 mineral discovery potential. The key project area and most advanced target with historic drilling is Horse Well, located 2 km west of BHP’s Oak Dam (1.34 Bt @ 0.66 percent copper and 0.33 g/t gold). Strategically positioned within the Olympic Dam Lineament Corridor, a structural feature closely associated with significant IOCG systems, the project demonstrates substantial geological promise.
The Horse Well Prospect features a large ovoid conductive anomaly measuring 4.2 km in strike length and 1.9 km in width which is significantly larger than BHP’s Oak Dam deposit. Although historic drilling on its own accord is impressive, the recent maiden geophysics model shows these intercepts have narrowly missed the core of this anomaly – including 115 m @ 0.62 percent copper equivalent, 61 m @ 0.33 percent copper equivalent, and 70 m @ 0.67 percent copper equivalent, which confirm the presence of a mineralized halo, highlighting the assets tremendous potential, once intersecting the core of the IOCG.

The Pernatty C Prospect hosts untested conductive anomalies with geological characteristics akin to a high-grade polymetallic deposit, with structural mapping identifying cross-cutting faults acting as conduits for mineralizing fluids.
At Lake Torrens, gravity anomalies two to three times the size of Oak Dam’s suggest the presence of large-scale, untapped IOCG mineralization. Furthermore, Lake Torrens sits on a key annular mantle disruption, similar to the positioning of Olympic Dam and Oak Dam West and is located on the rare PD1 Lineament Corridor, famously used to target the Olympic Dam discovery.
Substantial exploration work has advanced the Olympic Domain project, refined its geological models and identified high-priority targets. Advanced AMT and magnetic surveys have delineated major conductive zones coinciding with structural and magnetic anomalies, located just 5 km northwest of BHP’s Oak Dam deposit, providing a clear focus for exploration. Structural mapping has revealed extensive faulting and brecciation, serving as pathways for IOCG fluid systems.
The project is bolstered by exceptional infrastructure that enhances its development and exploration potential. Proximity to major regional highways ensures efficient logistics for exploration and future operations. The site is also well-positioned near smelters, industrial hubs, and export ports, ensuring access to critical resources and services. South Australia’s mining-friendly jurisdiction provides a supportive regulatory environment and a skilled workforce, further strengthening the project’s viability.
Altair has developed an aggressive exploration strategy to fully unlock the project’s potential. A focused drilling campaign, planned for 2025, will target the untested cores of major geophysical anomalies, including the high-priority ovoid conductor at Horse Well. The company is undergoing negotiations with potential JV partners which will provide a non-dilutive pathway to unlocking full value for the asset and allow Altair to proceed with its endeavours in making a globally significant discovery within its wholly owned Olympic Domain project. Enhancements to AMT and an imminent follow-up TEM will refine anomaly resolution and allow for precise drill targeting. Efforts will focus on validating Tier-1 IOCG targets, with the potential for discoveries comparable to neighboring world-class deposits like Oak Dam.

Top 5 Canadian Mining Stocks This Week: Onyx Gold Shines with 118 Percent Gain
Welcome to the Investing News Network's weekly look at the best-performing Canadian mining stocks on the TSX, TSXV and CSE, starting with a round-up of Canadian and US news impacting the resource sector.
Statistics Canada released April’s gross domestic product (GDP) numbers on Friday (June 27). The data showed a slowing in the Canadian economy with a 0.1 percent monthly decline after it increased 0.2 percent in March as businesses attempted to get ahead of US tariff deadlines.
In April, the shift in US trade policy led to significant declines in the manufacturing sector, which saw its largest drop in four years at 1.9 percent. Durable goods manufacturing declined for the first time in four months, dropping 2.2 percent d. The most heavily impacted sub-sectors were transportation equipment and the auto sector, which fell 21.6 percent and 5.2 percent, respectively.
On the positive side, finance and insurance experienced growth of 0.7 percent, with investment services and funds contributing 3.5 percent growth to the sector. StatsCan indicated that the US tariff announcement on April 2 led to increased selling activity in Canadian equity markets.
The Canadian resource sector was flat overall during the month. The oil and gas extraction, excluding oil sands, fell 1.1 percent in April, while oil sands extraction remained unchanged. The agency said that higher bitumen extraction was offset by lower synthetic crude production. Additionally, a temporary shutdown in the Keystone pipeline due to a rupture contributed to a decline in activity.
However, losses were offset by a 4.8 percent gain in support activities for the mining and oil and gas extraction subsectors, with an increase in rigging and drilling activities.
While some of the month-over-month decline was due to the increase in output in March, StatsCan suggests that further slowing is on the way. The agency reported that advanced figures for May show a further 0.1 decline, noting a decrease in the mining, quarrying, and oil and gas extraction category.
South of the border, the US Bureau of Economic Activity released May’s personal consumption expenditures price index (PCE) data on Friday. The index is a key inflation indicator and is the preferred measure used by the Federal Reserve when making its rate decision. The central bank has held its current rate at the 4.25 to 4.5 percent range since it last lowered it in November 2024.
The report shows inflation ticked up 2.3 percent on an annualized basis, higher than the 2.2 percent recorded in April. The increase came after two consecutive months of slowing from 2.7 percent in February and 2.3 percent in March.
Less the more volatile food and energy categories, PCE gained 2.7 percent during the period. While costs for goods increased, current-dollar personal income was down 0.4 percent and disposable income fell 0.6 percent.
US President Donald Trump again signaled his displeasure with the slow pace of rate cuts earlier in the week, and with the Wall Street Journal reporting on Wednesday (June 25) that he may announce a replacement for Chairman Jerome Powell as early as this summer.
While it’s unclear if he will try to remove Powell from the post, the president may try to create a “shadow Fed” that could work to influence markets and undermine decisions made by the current chairman. Powell’s term as chairman is set to expire in May 2026, while his time as board governor won’t end until 2028. His removal would require an act of Congress.
Markets and commodities react
In Canada, major indexes ended the week up. The S&P/TSX Composite Index (INDEXTSI:OSPTX) gained 0.77 percent during the week to close at 26,687.14 on Friday. The S&P/TSX Venture Composite Index (INDEXTSI:JX) fared better, gaining 1.47 percent to 724.26, while the CSE Composite Index (CSE:CSECOMP) climbed 0.74 percent to 117.39.
US equities were also in positive territory this week, with the S&P 500 (INDEXSP:INX) gaining 3.41 percent to close at a record high of 6,173.08, the Nasdaq-100 (INDEXNASDAQ:NDX) surging 4.17 percent to its own all-time high of 22,534.20. While it didn't break its previous high, the Dow Jones Industrial Average (INDEXDJX:.DJI) also climbed significantly, up 3.89 percent to 43,819.26.
On the other hand, the gold price declined this week, falling 2.8 percent to US$3,274.15 by Friday at 4 p.m. EDT. The silver price ended the week down just 0.05 percent at US$35.99.
In base metals, the COMEX copper price surged 5.59 percent over the week to US$5.12 per pound. Prices have been rising due to increased purchases ahead of US tariffs and significant drawdowns of inventories in London Metals Exchange warehouses.
Meanwhile, the S&P GSCI (INDEXSP:SPGSCI) lost 6.07 percent to close at 545.71.

A preliminary economic assessment released on January 6 demonstrated a post-tax net present value of US$1.08 billion with an internal rate of return of 23 percent and a payback period of 5.3 years, assuming a copper price of US$4.15 per pound.
The included mineral resource estimate shows a total indicated resource of 2.5 billion pounds of copper, 21.7 million ounces of silver and 140,042 ounces of gold from 402.83 million metric tons of ore with a grade of 0.31 percent copper, 1.85 parts per million (ppm) silver and 0.012 ppm gold. The majority is hosted at its Moonlight and Superior deposits.
Although the company did not release news this week, its shares have seen significant gains alongside a rising price of copper.
3. ArcWest Exploration (TSXV:AWX)
Weekly gain: 68.42 percent
Market cap: C$11.21 million
Share price: C$0.16
ArcWest Exploration is an exploration company that has most recently been working to advance its Todd Creek and Oweegee Dome properties within the Golden Triangle in British Columbia, Canada.
The Todd Creek property is a 21,343 hectare site that adjoins Newmont’s (TSX:NGT,NYSE:NEM) Brucejack property and hosts widespread copper and gold mineralization. Historical exploration of the site yielded grab samples with up to 37.7 g/t gold and 5.3 percent copper. The project is covered by a March 2023 earn-in agreement with Freeport-McMoRan (NYSE:FCX) that could see Freeport earn a 51 percent stake, with C$20 million in investments over a five year period.
The 31,077 hectare Oweegee Dome property is located 34 kilometers northeast of the Brucejack mine and hosts underexplored copper and gold systems, including Delta and Skowill East. Oweegee Dome is covered by a July 2021 option agreement with Sanatana Resources (TSXV:STA). Under the terms of the agreement, Sanatana can earn an initial 60 percent interest in the property through cumulative exploration investments of C$6.6 million over four years.
Shares in ArcWest gained this week after a pair of announcements.
The first came on Wednesday, when the company reported results from a 2024 drill program, funded and operated by Sanatana, that extended the mineralized zone at Oweegee Dome. Sanatana President Buddy Doyle said, “We now think the alteration and mineralization we see at surface at Delta is only the southeast corner of a larger system.”
The other news was released on Thursday, when it announced it had mobilized for a drill program at Todd Creek. The program will receive a minimum of C$4 million in funding from Freeport-McMoRan.
4. Belo Sun (TSXV:BSX)
Weekly gain: 62.79 percent
Market cap: C$163.35 million
Share price: C$0.35
Belo Sun Mining is an exploration and development company focused on advancing its Volta Grande gold project in Brazil.
The property covers approximately 2,400 hectares within the Tres Palmeiras greenstone belt in Para State, Brazil. The company has been working on the project since 2003, and acquired necessary development permits in 2014 and 2017.
A 2015 mineral reserve estimate demonstrated a proven and probable reserve of 3.79 million ounces of gold from 116 million metric tons of ore with an average grade of 1.02 g/t.
Development at the site stalled in 2018 after a federal judge ruled that the Federal Brazilian Institute of the Environment (IBMA) would be the competent authority for issuing environmental permits. The decision was overturned in 2019 with the Secretariat of Environment and Sustainability of the State of Para (SEMAS) reassuming its permitting authority. The decision was once again reversed in September 2023, returning authority to IBMA.
On January 23, Belo Sun announced that the Federal Court of Appeals had reassigned SEMAS as the permitting authority for the Volta Grande project. The company said it was pleased with the decision, as the agency is familiar with the project and enjoys a constructive and transparent relationship with it.
On Monday (June 23), the company announced shareholders approved a renewal of the company’s governance structure and elected four new directors to the board. Four of the board's six members are now either Brazilian or have spent significant parts of their careers working in Brazil.
5. Reyna Silver (TSXV:RSLV)
Weekly gain: 52.94 percent
Market cap: C$33.05 million
Share price: C$0.13
Reyna Silver is a silver exploration company with a portfolio of assets in Chihuahua, Mexico, and Nevada, US.
One of its two Mexican assets is Guigui, a 4,750 hectare property covering a significant portion of the Santa Eulalia Mining District. The area has a history of mining dating back to the 1700s with production of almost 450 million ounces of silver between then and 2001.
Its other one is Batopilas, a 1,183 hectare site that covers 94 percent of the Batopilas Mining District, which has significant deposits of pure, native silver. Historic mining at the site produced an estimated 200 million to 300 million ounces of silver dating back to the mid-1600s.
Its primary American asset is the Gryphon Summit project located along the Carlin-trend. The project covers an area of 10,300 hectares and is prospective for gold, silver and critical minerals.
It also owns the Medicine Springs project, which spans 4,831 hectares south of Elko City. Previous exploration at the site identified lead, zinc and silver mineralization.
Shares in Reyna gained this week after it entered into a definitive agreement to be acquired by Torex Gold (TSX:TXG).
The deal, valued at US$26 million, will see Torex acquire all issued and outstanding common shares in Reyna, thereby gaining access to its wholly owned Mexican portfolio. Additionally, Torex will have the option to acquire a 70 percent stake in the Gryphon Summit project and a 100 percent interest in Medicine Springs.

What is the difference between the TSX and TSXV?
The TSX, or Toronto Stock Exchange, is used by senior companies with larger market caps, and the TSXV, or TSX Venture Exchange, is used by smaller-cap companies. Companies listed on the TSXV can graduate to the senior exchange.
How many mining companies are listed on the TSX and TSXV?
As of February 2025, there were 1,572 companies listed on the TSXV, 905 of which were mining companies. Comparatively, the TSX was home to 1,859 companies, with 181 of those being mining companies.
Together the TSX and TSXV host around 40 percent of the world’s public mining companies.
How much does it cost to list on the TSXV?
There are a variety of different fees that companies must pay to list on the TSXV, and according to the exchange, they can vary based on the transaction’s nature and complexity. The listing fee alone will most likely cost between C$10,000 to C$70,000. Accounting and auditing fees could rack up between C$25,000 and C$100,000, while legal fees are expected to be over C$75,000 and an underwriters’ commission may hit up to 12 percent.
The exchange lists a handful of other fees and expenses companies can expect, including but not limited to security commission and transfer agency fees, investor relations costs and director and officer liability insurance.
These are all just for the initial listing, of course. There are ongoing expenses once companies are trading, such as sustaining fees and additional listing fees, plus the costs associated with filing regular reports.
How do you trade on the TSXV?
Investors can trade on the TSXV the way they would trade stocks on any exchange. This means they can use a stock broker or an individual investment account to buy and sell shares of TSXV-listed companies during the exchange's trading hours.

Top 5 Australian Mining Stocks This Week: GBM Soars on AU$13 Million Raise
Welcome to the first edition of the Investing News Network's weekly round-up of Australia’s top-performing mining stocks on the ASX, starting with news in Australia's resource sector.
In significant news for Australia's iron sector, mining giant Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), together with its joint venture partner Hancock Prospecting, said on Tuesday (June 24) that the partners will invest a combined US$1.6 billion to develop the Hope Downs 2 iron ore project in the Pilbara region, Western Australia.
Companies focused on antimony and gold have also been making news this week, such as Resolution Minerals (ASX:RML) announcing its acquisition of the Horse Heaven project in Idaho, US, and Ausgold (ASX:AUC,OTC Pink:AUSGF) signing an agreement to acquire Critica’s (ASX:CRI,OTC Pink:VTMLF) Kulin gold project in Western Australia.
This week, Resolution was one of two companies focused on antimony to make the top ASX mining stocks list. Antimony has been gaining attention as supply falls and prices hit record highs following China's export controls earlier in the year. The metal is critical to the defense and lead-acid battery industries. In a report by Reuters, the executive director of a US battery association said the shortage of the key mineral is a national emergency with no quick solution.
Market and commodity price round-up
The S&P/ASX 200 index opened at 8,505.50 on Monday (June 23) and closed at approximately 8,550.20 on Friday (June 27). This reflects a modest 0.53 percent gain over the week.
For metals, the gold price declined by 2.8 percent, opening at US$3,368.57 per ounce on Monday and closing at US$3,274.15 at 6 a.m. AEST, June 28. Its price in Australian dollars fell by 4 percent from AU$5,221.02 to AU$5,013.71 by the week's end.
The US silver price ended the week neutral, moving from a US$36.01 open on Monday to a US$35.99 close on Friday. However, in Australian dollars, it opened at AU$55.81 per ounce and pulled back 1.24 percent to AU$55.12.
Top ASX mining stocks this week
How did ASX mining stocks perform against this backdrop?
Take a look at this week’s five best-performing Australian mining stocks below as we break down their operations and why these mining stocks are up this week.
Stock data for this article was retrieved at 4 p.m. AEST on June 26 using TradingView's stock screener. Only companies trading on the ASX with market capitalizations greater than AU$10 million are included. Mineral companies within the non-energy minerals, energy minerals, process industry and producer manufacturing sectors were considered.
1. GBM Resources (ASX:GBZ)
Share price: AU$0.013
Market cap: AU$16.37 million
Weekly gain: 116.67 percent
GBM Resources is a Brisbane-based exploration and development company focusing on the discovery of world-class gold and copper deposits in Queensland.
Its flagship asset is a fully owned group of projects — Yandan, Twin Hills and Mt Coolon — located in the Drummond Basin, among Australia’s major gold provinces with a production history of over 4.5 million ounces.
Combined, the three Drummond Basin projects host 1.84 million ounces of gold and a total project area of 4,667 square kilometres.
The Mt Coolon project is subject to a farm-in partnership between GBM and leading gold producer Newmont (NYSE:NEM,TSX:NGT). In late April, Newmont released final assays from its Phase 1 drill program at Mt Coolon.
On Tuesday (June 24), GBM announced that it has received firm commitments to raise AU$13 million, which it will use in part to repay and cancel all of its existing convertible notes with Collins St Asset Management worth AU$6.2 million. Upon repayment, GBM will be debt-free and well-funded to advance its Yandan and Twin Hills assets with the goal of expanding its gold resource base.
The placement also includes several board and management changes, with Peter Rohner stepping down as managing director immediately and as CEO once his contract expires on July 31.
Shares of GBM soared to AU$0.014 on Tuesday following the announcement of the placement and recapitalization strategy.
2. Locksley Resources (ASX:LKY)
Share price: AU$0.088
Market cap: AU$10.82 million
Weekly gain: 41.94 percent
Locksley Resources is an exploration company focused on its flagship Mojave project in California, a rare earths and antimony asset situated near MP Materials’ (NYSE:MP) Mountain Pass mine, the only operational REE mine in the US. It also owns copper, gold and base metal assets in Australia.
Mojave is located on California’s south-eastern border with Nevada.The project hosts two mineralisation zones, the El Campo rare earth elements prospect, which hosts rare earths including neodymium and praseodymium, and the past-producing Desert antimony mine area, which hosts antimony, silver, lead and zinc. Rock chip sampling returned grades up to 12.1 percent total rare earth oxides at El Campo, and up to 46.1 percent antimony and 1,022 grams per tonne silver at the Desert antimony mine.
After starting May at AU$0.019, Locksley’s share price saw a boost on May 8 following the federal endorsement of Dateline Resources’ (ASX:DTR,OTC Pink:DTREF) Colosseum gold-rare earths project, which is located in the same district as Mojave. Locksley stated it would use this precedent to pursue government support.
Its share price climbed even higher after the company announced a capital raising on May 28 to fund exploration at Mojave. It peaked at AU$0.115 on June 4. The upcoming drilling program will focus on El Campo, with five RC holes targeting rare earths at the site, and is planned for the last quarter of 2025. The company secured the drilling permit on June 5.
On June 17, Locksley announced a strategic US collaboration for the project, saying that it aims to align its antimony and rare earth elements assets with the US’ critical minerals strategy. The company successfully completed an OTCQB listing on June 26 to expand its US market presence; it will trade under the symbol LKYRF.
3. Noble Helium (ASX:NHE)
Share price: AU$0.026
Market cap: AU$14.39 million
Weekly gain: 36.84 percent
Noble Helium is a helium exploration company with four key projects in Tanzania, namely North Rukwa, North Nyasa, Eyasi and Manyara. North Rukwa, the company’s flagship project, covers a total area of approximately 1,467 square kilometres.
Exploration at the project is currently ongoing. Noble raised AU$3 million in September 2024, with proceeds allotted for North Rukwa and North Nyasa.
Last week, Noble announced a trading halt following a sudden jump of its shares from AU$0.012 on June 16 to AU$0.019 on June 19.
Addressing the jump on Monday, June 23, the company stated it believed the rise does not stem from undisclosed information, and the only material development was ongoing negotiations for amendments to a funding agreement with private company Obsidian Global.
The original agreement, which would have raised US$2.5 million through convertible notes to fund ongoing exploration and working capital, was made public on December 24, 2024.
Before resuming trading Monday, Noble announced it successfully executed the amendment. Shares of the company continued on their upward trend following these developments, peaking at AU$0.034 on Wednesday (June 25).
4. Mindax (ASX:MDX)
Share price: AU$0.064
Market cap: AU$146.8 million
Weekly gain: 28 percent
Mindax is an exploration and development company with iron ore and gold assets in Western Australia.
Its flagship project is the Mt Forrest magnetite iron ore project, in which it holds a 65 percent interest in a joint venture with Norton Gold Fields, which holds the remaining 35 percent.
According to a February 2023 report, Mt Forrest is estimated to contain 422.37 million tonnes of indicated resources at average grades of 41.42 percent mass recovery and 64.76 percent iron concentrate, as well as 599.4 million tonnes of inferred resources at average grades of 43.14 percent mass recovery and 63.85 percent iron concentrate.
On April 15, Mindax announced that it used its existing cash reserves for a 5 percent strategic investment in Cashmere Iron, an unlisted public company.
Cashmere Iron’s flagship Cashmere Downs iron project sits adjacent to Mindax’s Mt Forrest project. Mindax said that the decision to invest in Cashmere follows its review of various independent technical reports outlining the project's potential.
“As a neighbour in the Mid-West region, Mindax is familiar with Cashmere and its assets, having followed the progress made by the Cashmere management team in advancing the project over many years,” the company said, calling the investment “a vital step” in its goal of consolidating iron resources in the mid-west region of Western Australia
5. Resolution Minerals (ASX:RML)
Share price: AU$0.052
Market cap: AU$33.22 million
Weekly gain: 26.83 percent
Resolution Minerals acquires, explores and develops precious and battery metals projects such as antimony, gold, copper and uranium.
The company is currently building a portfolio of gold and antimony assets, and recently acquired the antimony-gold-tungsten Horse Heaven project as part of this strategy.
Horse Heaven is located 5 kilometres from Perpetua Resources' (TSX:PPTA,NASDAQ:PPTA) Stibnite gold-antimony project in Idaho. Stibnite received final approval from the US Forest Service in January, and construction is expected to begin in late 2025. If it enters production, it will become the US’ only antimony producer.
The Horse Heaven project has a historic non-JORC gold resource of 216,000 ounces of gold at the Golden Gate Hill target, and a gold resource of 70,000 ounces at the Antimony Hill prospect.
In March, Resolution Minerals also secured three projects in Australia, including the Drake East antimony-gold project in New South Wales and Neardie antimony project in Queensland.
Last week, Resolution announced it selected external affairs adviser Clewett Global Services to assist with engaging the US federal government. The company added that it is considering applying for US Department of Defense (DOD) funding to expedite Horse Heaven.
Resolution is also currently working on an OTCQB listing to appeal to North American Investors.
