RC hole FRC378 returned 12 metres at 7.26g/t Au from 23 metres and 25 metres at24.3g/t Au from 68 metres, including a very high-grade zone of 3 metres at 177g/t Au from 74 metres
Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report assay results for the first 20 holes for 2,580 metres of a 31-hole (3,834 metre) in-fill and extensional RC drill program at the Kamperman Prospect, part of the 100%-owned Feysville Gold Project (Feysville), located approximately 14km south of Kalgoorlie in Western Australia (Figure 1).
HIGHLIGHTS
- Assay results received for the first 20 holes (2,580 metres) of a 31-hole (3,834 metre) reverse circulation (RC) drill program at Feysville’s Kamperman Prospect, with best results including:
- 12 metres at 7.26g/t Au from 23 metres including 1 metre at 16.5g/t Au from 24 metres and 1 metre at 39.7g/t Au from 27 metres and, further down-hole, 25 metres at 24.3g/t Au from 68 metres, including 1 metre at 28.0g/t Au from 69 metres and 3 metres at 177g/t Au from 74 metres in hole FRC378;
- 12 metres at 1.96g/t Au from 20 metres and 5 metres at 1.25g/t Au from 58 metres in hole FRC377;
- 4 metres at 2.95g/t Au from 61 metres and 11 metres at 0.96g/t Au from 91 metres in hole FRC372; and
- 18 metres at 0.90g/t Au from 25 metres in hole FRC371.
- RC holes FRC377 and FRC378 were designed to in-fill the northern end of the Kamperman prospect while also testing for potential north-plunging mineralisation, as characterised by previous intercepts of 14 metres at 1.44g/t Au from 54 metres in hole FRC304 and 12 metres at 1.99g/t Au from 78 metres in hole FRC341.
- The results from RC holes FRC377 and FRC378 are encouraging, and diamond drilling (DD) is planned in this area to better understand the orientation of the very high-grade zone in hole FRC378.
- Step-out holes to the north and north-east intersected gold mineralisation, demonstrating that Kamperman remains open to the north.
- Further assay results from the Kamperman program are pending.
- The RC rig is currently undertaking a program of several drill holes at Mandilla to determine dewatering requirements as part of the hydrogeological work program for the Mandilla Pre- Feasibility Study (PFS).
- At the Iris Deposit, a program of ten holes for 1,365 metres of in-fill drilling has been completed with a further ten holes remaining to be drilled. At the Eos Deposit, 16 holes for 2,540 metres will be drilled shortly.
- At Mandilla, a DD rig has commenced a four-hole/1,600 metre drill program of four deep in-fill holes ahead of an update to the Theia Mineral Resources Estimate (MRE), which is expected to be reported in the March Quarter, 2025.
Astral Resources’ Managing Director Marc Ducler said: “These latest holes at Kamperman continue to surprise to the upside – showing that there is a potentially very significant high-grade opportunity here that we are yet to unlock.
“Previously, FRC243 returned a very high-grade zone of two metres at 188g/t Au from 77 metres, 40 metres to the north-east. FRC378 has now returned another very high-grade zone of three metres at 177g/t Au from 74 metres.
“Previous diamond drilling that was completed to better understand the potential orientation of this very high-grade zone was not successful; however, given the potential size of the prize, additional work is warranted.
“The extensional drilling completed to the north and north-east has continued to intersect gold mineralisation, albeit the gold grades were of a lower tenor than expected given the quantum of quartz and sulphides logged in the RC chips. Additional RC drilling is planned given the proximity to a north- east trending fault which is potentially controlling the mineralisation or offsetting it.
“It is becoming clear that Kamperman hosts multiple potential controlling structures that warrant further investigation, as does Feysville as a whole.
“The in-fill RC program at Iris is 50% complete. The program is now on hold for approximately three weeks while groundwater testing is undertaken with the RC rig. Once the groundwater program is complete, RC drilling will resume at Iris and Eos.
“Meanwhile, diamond drilling is now underway at Theia with four deep in-fill holes for 1,600 metres planned. These holes are designed to provide the level of confidence required to warrant an upgrade of the Inferred Resources at depth into the Indicated Resource category.”

FEYSVILLE GOLD PROJECT
The Feysville Gold Project is located within the north-north-west trending Norseman – Wiluna Greenstone Belt, within the Kambalda Domain of the Archean Yilgarn Craton, approximately 14km south of the KCGM Super Pit in Kalgoorlie.
Significant gold and nickel mineralisation occurs throughout the belt, including world-class deposits such as the Golden Mile Super Pit in Kalgoorlie owned by Northern Star Resources Limited (ASX: NST) and the St Ives Gold Mine south of Kambalda owned by Gold Fields Limited. The area also hosts the substantial Beta Hunt Gold Mine owned by Westgold Resources Limited (ASX: WGX).
Feysville hosts an MRE of 3Mt at 1.3g/t Au for 116koz2 of contained gold at the Think Big deposit, providing a foundation for the project to potentially become a source of satellite ore feed for a future operation based on Astral’s flagship Mandilla Gold Project.
Locally, Feysville has been interpreted to contain upthrust ultramafics, emplaced within a sequence of volcanic sediments (the Black Flag sediment group), granitic intrusions, mafic basalts, gabbro and andesite. A map of the Feysville Gold Project identifying tenements and deposits/prospects on local area geology is set out in Figure 2.

Investor Insight
Astral Resources presents a compelling investment case as an ASX-listed gold explorer with a 1.46 Moz resource base in Western Australia's premier Kalgoorlie region, anchored by its flagship Mandilla project which demonstrates robust economics with an AU$442 million NPV and 11-year mine life.
Overview
Astral Resources (ASX:AAR) is a gold mineral exploration company with three gold projects in tier 1 mining jurisdictions of Western Australia. The three assets are the Mandilla gold project, the Feysville gold project, and the Carnilya Hill gold project. The flagship and 100 percent owned Mandilla gold project has a mineral resource containing 1.27 million ounces (Moz) of contained gold. The other key project, 100 percent owned Feysville, hosts an updated Mineral Resource Estimate (MRE) of 5.0 Mt at 1.2g/t gold for 196 koz of contained gold . Feysville could potentially become a satellite source of high-grade ore feed for the flagship Mandilla gold project.
The scoping study completed at Mandilla unveils robust project economics. The cornerstone of the scoping study is the Theia deposit, which alone accounts for 81 percent of the total Mandilla mineral resource estimate. The deposit hosts a mineral resource estimate of 29 Mt at 1.1 g/t gold for 1.02 Moz of contained gold in one large open pit. The scoping study indicates a mine life of 11 years with an annual production of 100,000 oz in the first seven and a half years, dropping to 41,000 oz for the remaining three and a half years. The study outlines compelling financial metrics, including NPV@8 percent of AU$442 million, free cash flow of AU$740 million, and a payback period of nine months.
Astral benefits from a team of professionals boasting extensive expertise in geology and mining.
The company is led by managing director Marc Ducler, who has more than two decades of experience in the mining industry. The management team has a proven track record of executing several successful exploration and development projects, as well as M&A.

Key Projects
Mandilla Gold Project
The Mandilla gold project is located within the northern region of the Widgiemooltha greenstone belt, approximately 70 kilometers to the south of the prominent mining hub of Kalgoorlie, Western Australia. Mandilla includes four deposits namely, Theia, Iris, Eos and Hestia. The cornerstone of the project is the Theia deposit, constituting 81 percent of Mandilla's resources, totaling 29 Mt at a grade of 1.1 g/t gold, amounting to 1.02 Moz of contained gold in a single open pit. Mandilla has a total mineral resource estimate of 37 Mt at 1.1 g/t gold for 1.27 Moz.
The scoping study indicates a mine life of 11 years with an annual production of 100,000 oz in the first seven and a half years, dropping to 41,000 oz for the remaining three and a half years. Astral estimates the pre-production capital spend at AU$191 million, and the project is anticipated to generate a free cash flow of AU$740 million (assuming a gold price of A$2,750/oz). The project’s NPV @8 percent is estimated at AU$442 million, and the IRR at 73 percent.
Drill collars at Theia deposit
Astral continues to advance exploration and resource expansion efforts at Mandilla. The company recently completed a four-hole 1,762-metre in-fill diamond drilling program at the Theia deposit late last year. Best results included: 28 metres at 2.63 g/t gold, 15.5 metres at 1.81 g/t gold, 9.6 metres at 27.6 g/t gold, 2.4 metres at 169.1 g/t gold, 24.9 metres at 4.14 g/t gold and 72.2 metres at 1.15 g/t gold.
Astral has commenced work on a pre-feasibility study at Mandilla, which is due in the June quarter 2025.
Feysville Gold Project
The Feysville project is situated in Australia's premier gold belt, merely 14 km south of the Golden Mile deposit, which boasts 70 million ounces, located in Kalgoorlie. The project's updated JORC 2012 MRE indicates 5.0 Mt at 1.2 g/t gold for 196 koz of contained gold. Including the Mandilla MRE of 37 Mt at 1.1 g/t gold for 1.27 Moz of contained gold, Astral’s total gold MRE is now calculated to be 42 Mt at 1.1 g/t gold for 1.46 Moz of contained gold (group MRE).
At Feysville, Astral is focusing on the high-grade Kamperman prospect. A recent 31-hole (3,834 m) reverse circulation (RC) drilling program at Kamperman returned encouraging assay results. The latest drilling program returned best assay results of 33 metres at 3.75 g/t gold, 22 metres at 5.21 g/t gold, and 22 metres at 4.44 g/t gold. This high success rate continues to indicate that Kamperman has the potential to be a substantial source of high-grade satellite ore for the Mandilla processing plant.
Carnilya Gold Project
The Carnilya Hill gold project is situated about 20 kilometers south-southeast of the company's Feysville project and approximately 40 kilometers southeast of Kalgoorlie, Western Australia. The project encompasses various tenements – M26/047-049, M26/453 – spanning approximately 2.65 sq. km. Astral holds rights for gold mining, while Mincor Resources NL (ASX:MCR) holds rights to nickel and other minerals.Management Team

Wide Gold Intercepts at Mt York Support Future Resource Growth
Three diamond drill rigs on site at 1.4Moz Mt York Gold Project, WA, with 56% of Stage 1 resource drilling complete; Results extend mineralisation along strike and at depth; good continuity of higher-grade shoots confirms new structural model
Kairos Minerals Ltd (ASX:KAI) (“KAI” or the “Company”) is pleased to announce results from the first 16 diamond holes drilled at its Mt York Gold Project in WA’s Pilbara, where current resources at the Main Trend sit at 1.4Moz Au. The results are from Gossan Hill (7 holes), Breccia Hill (5 holes) and Main Hill (4 holes) (Table 1), and are shown on drill plan (Figure 1) and long-section (Figure 2).
Highlights
- 36 holes for 10,025m completed at Mt York, ahead of schedule and on-budget; Stage 1 is an 80-hole, 18,000m resource expansion program
- Results for 16 holes received, with best intercepts including:
- 21m @ 1.87 g/t Au from 169m incl 9m @ 3.19 g/t Au (25MYDD009);
- 5m @ 4.26 g/t Au from 299m (25MYDD010);
- 34m @ 0.81 g/t Au from 242m incl 7m @ 2.66 g/t Au from 269m (25MYDD012);
- 24m @ 1.17 g/t Au from 222m incl 7m @ 2.62 g/t Au from 222m (25MYDD016);
- 48m @ 1.03 g/t Au from 227m incl 11m @ 3.38 g/t Au from 264m (25MYDD017).
- Higher-grade mineralisation consistently reported across Main Trend confirming and extending high-grade shoots at all prospects
- Encouraging first results likely to positively impact grades and widths of mineralisation for an updated resource estimate later in 2025
- Drilling accelerated with third diamond drill rig capable of low-angle drilling on site at the highly prospective but under-drilled Main Hill Prospect
Stage 1 drilling aims to boost gold resources at Mt York and test extensions of high- grade shoots ahead of a mineral resource estimate (MRE) update expected in 2H CY25. Stage 2 drilling later in the year or early 2026 aims to convert Inferred resources to higher confidence Indicated resources.
Kairos Managing Director Dr Peter Turner said: “The first results from Mt York continue to reinforce our belief in the potential scale of this project, and we are on track to deliver a new and much improved mineral resource estimate later in 2025 incorporating at least 18,000m of additional drilling results. We continue to ask ourselves ‘how big is the Mt York gold resource’ and will increase and expand Stage 1 drilling if we believe the mineralisation continues to be open which appears to be the case at the moment.
We are seeing good widths of mineralisation in areas where the resource model is unguided and importantly, solid higher-grade gold intercepts within the lower-grade envelopes. From the previous 2023 resource, Mt York has more than 750,000 ounces of gold at 1.6 g/t Au and the current drilling is confirming that high-grade shoots are both horizontal within the system, but also likely to be extensive (>300m) along-strike in both footwall and hangingwall positions. This is great news.
We are drilling the western half of the large Main Hill Prospect where the mineralised banded iron formation (BIF) host rocks attain 100m in true thickness but where topographic challenges previously prevented drilling. With a suitable small-footprint rig now in place, we can see an assemblage of sulphide-bearing BIF in many drill holes in this area that is associated with free-milling gold mineralisation in other parts of the Main Trend.
With drilling scheduled to continue into September and possibly beyond, we look forward to releasing results as they become available.
We are confident Mt York will become one of the Pilbara’s (and Western Australia’s) largest undeveloped gold resources with clean metallurgy once drilling is complete.”
Drill Results
Results from the first 16 holes are shown in Table 1. The Stage 1 drill holes have been designed to test the grades and widths of mineralisation and purposely looking for extensions of higher-grade pods within the entire 3,000m-long Main Trend Gold Deposit. The positions of the drill holes and their results are shown on Figure 1 (plan view) & Figure 2 (long-section).
Holes 25MYDD007 to 25MYDD009 test gaps in the resource model at Breccia Hill and confirm multiple zones of mineralisation, where 25MYDD009 returned high-grade core of 9m @ 3.19 g/t Au from 176m. This confirms the extension of a high-grade pod of mineralisation some 75m away from historic drillhole KMYD040’s result of 10m @ 4.90 g/t Au from 257m1, that confirms that higher-grade mineralisation may well form significant, horizontal zones previously not recognised yet confirmed in recent structural interpretation.
Deeper drilling into the eastern side of Main Hill has infilled and extended mineralisation with holes 25MYDD010, 012, 014 and 017. Big gains in both mineralisation width and grade are captured in hole 25MYDD017 that intercepted multiple zones including 48m @ 1.03 g/t Au from 227m including a higher-grade zone of 11m @ 3.38 g/t Au from 264m. This extends a new zone of high-grade mineralisation on the footwall position and forms part of the horizontal-plunging, high-grade zone drilled >300m to the west in hole 25MYDD012 (7m @ 2.66 g/t Au from 269m) extending to 25MYDD010 (5m @ 4.26 g/t Au from 299m) (see Figure 2). Another 5 drillholes are planned to the west of these holes to test the extension of the high-grade mineralisation for a further 500m to the west (Figure 1).
The results of the mineralised intercepts are considered close to true widths as the mineralisation has been intercepted orthogonally.
A third diamond drill rig (DDH1 drill rig #83) capable of low-angle drilling has been sent to site to accelerate the program, especially at the poorly tested but prospective Main Hill Prospect. Historic drill results of 109m @ 2.09 g/t Au from 50m (MYD24A) entirely in banded iron formation (BIF) host rocks demonstrate the importance of this prospect. The mineralised banded iron formation (BIF) rocks are the thickest (~100m true thickness) in the area but due to the topographic and access challenges around the hill, the Main Hill target has, until now, been inaccessible for drill rigs.
Holes 25MYDD001-006 are largely testing the mineralised banded iron formation (BIF) on the extreme eastern end of the Main Trend at Gossan Hill.
Rig #83 is drilling the Main Hill Prospect extensively from both the northern and southern sides of the hill (see Photo 2) to truly understand the scale of the resource in this area. There is plenty of evidence that high-grade mineralisation exists at this prospect. Results for these holes (25MYDD023, 028, 031, 032, 033, 034 – see Figure 1 and 2 for location of holes) are awaited.
Further drill results are expected throughout July, August and September and will be released to the ASX once routine quality-assurance, quality-control (QAQC) checks have been completed.

5 Best-performing Gold Stocks on the TSX in 2025
The gold price soared to new record highs during the second quarter of 2025, the most recent coming when it climbed to C$4,663.85, or US$3,433.47, on June 13.
Several factors fueled gold price momentum toward the end of the second quarter, including an escalation in Middle East tensions as Israel and Iran entered into direct conflict. Although a cease fire was announced, it came after the United States dropped several 30,000 pound bombs on key Iranian nuclear sites.
Additional support for gold has come from continued uncertainty in global financial markets as the US's tariff strategy continues.
Since the beginning of the year, investors have sought the relative safety of gold and gold-backed investment products, which have pushed the price up more than 25 percent.
Against that backdrop, which TSX-listed gold stocks have performed the best? The companies listed below have been the top performers this year. Data was retrieved on July 2, 2025, using TradingView's stock screener. Only companies with market capitalizations greater than C$50 million are included.
1. Belo Sun (TSX:BSX)
Year-to-date gain: 276.47 percent
Market cap: C$144.68 million
Share price: C$0.32
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 Pará 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 gold grade of 1.02 per metric ton (g/t).
Development at the site stalled in 2018 after a federal judge ruled that the Federal Brazilian Institute of the Environment (IBAMA) 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 Pará (SEMAS) reassuming its permitting authority. The decision was once again reversed in September 2023, returning authority to IBAMA.
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.
The most recent news came on June 23, when the company announced that shareholders had 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.
Shares in Belo Sun reached a year-to-date high of C$0.35 on June 16.
2. Euro Sun Mining (TSX:ESM)
Year-to-date gain: 200 percent
Market cap: C$53.71 million
Share price: C$0.135
Euro Sun Mining is a development-stage company advancing its Rovina Valley copper-gold project in Romania. The project’s mining license received full approval for 20 years in 2018, with the option to renew it in five year increments.
An updated feasibility study from March 2022 demonstrated the project's economics, showing a post-tax net present value of US$512 million and an internal rate of return of 20.5 percent, assuming a base case gold price of US$1,675 per ounce and a copper price of US$3.75 per pound.
Proven and probable mineral reserve estimates for the site include 1.84 million ounces of gold and 197,522 metric tons of copper from 123.3 million metric tons of ore with an average grade of 0.47 g/t gold and 0.16 percent copper.
Shares in Euro Sun saw their most significant gains around the same time as a March 25 announcement that the EU included Rovina Valley on its first list of strategic assets. The inclusion, which Euro Sun applied for in May 2024, will enable the company to expedite permitting at Rovina Valley and shorten the development timeline.
On May 7, Euro Sun reported it met with Romania’s Minister of the Environment to discuss the advancement of the project. Both parties agreed that a single point of contact was needed to ensure compliance and fulfill requirements under the CRMA framework. The company plans to submit an updated environmental act in the near future.
On June 20, Euro Sun reported it signed a copper concentrates prepayment facility for up to US$200 million with private metals trader Trafigura, with the funding going towards the necessary permitting and investment to advance Rovina over the next 18 months.
Shares in Euro Sun reached a year-to-date high of C$0.145 on June 2.
3. Collective Mining (TSX:CNL)
Year-to-date gain: 165.05 percent
Market cap: C$1.26 billion
Share price: C$15.85
Collective Mining is a gold, copper and silver exploration company with focused interests in Caldas, Colombia.
Its two projects, Guayabales and San Antonio, consolidate large portions of a mineral belt that surrounds Aris Mining's (TSX:ARIS,NYSE:ARMN)Marmato mine and within a region with 10 operating mines.
The Guayabales project comprises 26 claims spanning a total area of 4,780.98 hectares. Collective Mining has conducted extensive exploration at the property in 2025, with a primary focus on expanding the Apollo zone. The company also drilled multiple look-alike targets.
The most recent exploration report was released on June 30, when the company announced the discovery of a new high-grade vein system, with a highlighted assay of 534 g/t gold over 0.67 meters. However, the company stated that drilling was retargeted after results from a gravimetric survey indicated that the drill hole was outside the mineralized breccia body.
On June 23, Collective accelerated its agreement to acquire a 100 percent stake in the Guayabales property. Under the original agreement, Collective had until 2032 to make the required payments and incur the necessary exploration expenditures.
The company reported that the financial considerations remained the same under the amended agreement, but C$2 million would be paid immediately, with an additional C$2 million paid within one month of the title transfer request being filed and C$2.3 million after two months. The remaining C$3.5 million will now be paid out in six equal installments over a three-year period from the date of the amended agreement.
Shares in Collective Mining reached a year-to-date high of C$15.85 on July 2.
