Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to report on the second batch of Au assay results for the Burns Resource drill-out program currently underway at the Burns Copper (Cu)/Gold (Au) Project, which is within the Company’s wholly owned Eastern Lefroy Gold Project located 70km southeast of Kalgoorlie.
- The Burns Resource Drill-out program consists of 80 RC holes over 700m of strike length, with each hole evaluating a vertical depth of approximately 200m. Fifty-one holes have been completed, with the remaining 29 holes planned to be drilled before the end of December 2022.
- Gold only assay results have been received for holes LRR001-LRR003 located on Lake Randall, and 160m to the north of the Burns discovery hole, LEFR260. Copper and multi element results are pending.
- Hole LRR003, which is within the Central Porphyry zone, intersected an outstanding long downhole interval of gold mineralisation from immediately below the transported cover, as follows:
LRR003 – 103 m @ 1.65g/t Au from 25 m, including 38 m @ 3.83g/t Au from 26 m
- Drilling is currently underway to the north of these holes, where the mineralised system remains untested and open.
- Holes LRR001 and LRR002 were east of the Central Porphyry zone and returned weak gold values (0.4-0.6g/t) over downhole lengths of 20-30m.
- Assay results for the remaining 77 holes in the Burns Resource Drill-out program, including base metal values which are slower to be reported than the gold results, will be received between December 2022 and January 2023. Updates will be released as assays are received.
- The Burns Resource estimate will be finalised in Q1/2023.
Lefroy Exploration Managing Director Wade Johnson said, “The intersection in LRR003 is an outstanding result that will add significant value to the maiden Burns mineral resource estimate. LRR003 contains the strongest gold mineralisation intersected at Burns to date outside of the discovery hole LEFR260 and presents an opportunity to further expand the Burns system where mineralisation remains open to the north on Lake Randall. We’re very pleased with the progress of this drill program which places the Company in a great position to deliver the Burns resource estimate in Q1/ 2023.”
Burns is an intrusion-related Au-Cu-molybdenum (Mo) and silver (Ag) mineral system, hosted by multiple diorite-porphyry intrusives and high-magnesium basalt Archaean-age rocks. The Company considers this Au-Cu-Mo-Ag intrusion-related style of mineralisation to be entirely new and unique to the Eastern Goldfields Province (EGP) of Western Australia.
A maiden 22-hole Reverse Circulation (RC) drill program completed in Jan-Feb 2021 intersected a spectacular gold and copper interval in hole LEFR260, containing 38m @ 7.63g/t Au & 0.56% Cu from 134m in diorite porphyry. The results from that RC program provided the geological and geochemical data that highlighted the unique geological characteristics of Burns and are a key guide to subsequent and ongoing exploration activity.
Further targeted aircore, RC and diamond drilling at Burns since January 2021 has established a broad footprint to the system that extends beneath Lake Randall, with the limits of mineralisation still to be fully defined. The system may extend for 2000 metres or more along strike, based on drilling between Lovejoy in the north and the main Burns Central area in the south.
Reverse Circulation (RC) Resource Drill Program
In October 2022, the Company commenced the Burns Resource drill-out program of 15,000 planned metres to evaluate the Burns Central system to 200 metres vertical from surface and over 700 metres of strike (Refer LEX ASX Release 6 October 2022). The data from this program, when combined with previous drilling data, will support the compilation of a mineral resource estimate to be finalised in Q1/2023.
To date, 51 holes for 12,798 metres have been completed, both onshore (land-based) and offshore on Lake Randall (salt-lake based). Drill spacing is a nominal 40 metre by 40 metre grid pattern, with angled holes planned to a nominal final hole depth of 250 metres. The drill program is designed to evaluate the three key geological domains at Burns Central being the Central Porphyry, Western basalt, and Eastern deformation zone.
Gold only assay results have been returned for three drill holes, LRR001-003 (Table 1), collared to follow up multiple mineralised gold and copper intersections identified in previous aircore drilling.
The previous aircore drilling on Lake Randall (refer LEX ASX release 21 February 2022) 160m to the north of discovery hole (LEFR260), included significant mineralised intercepts of:
- 16m @ 3.79 g/t Au from 20m in LEFRA1088; including
- 8m at 7.31 g/t Au from 20m
- 24m @ 2.86 g/t Au from 16m to End-of-Hole in LEFA1089; including
- 16m @ 4.04g/t Au from 20m
Importantly hole LEFA1089 (Figures 1-3) ended in gold and copper mineralisation that included 8m at 1.91g/t gold and 0.31% copper from 32m to the end of hole. These results and those from other holes immediately northeast of the discovery section demonstrate the wider footprint of the Burns system.

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.
4. Starcore International (TSX:SAM)
Year-to-date gain: 150 percent
Market cap: C$19.06 million
Share price: C$0.325
Starcore International is a gold exploration and mining company with assets in Mexico, Canada and Côte d’Ivoire. Its primary asset is the San Martin mine in Queretaro, Mexico.
In the company’s fourth-quarter production results, released on May 13, it reported reaching a significant commissioning milestone in the new processing circuit and milling 5,000 metric tons of stockpiled ore.
The mine produced 3,242 gold-equivalent ounces during the quarter, up 3 percent from 2,268 ounces during the previous quarter. The company added that it was continuing to explore and develop a new area in the southern section of the mine.
Outside its Mexican operations, the main focus throughout 2025 has been its Kimoukro gold project in Côte d’Ivoire.
On April 9, Starcore reported results from 2024 exploration work at the project and an update on its activities at the project. In 2024, the company completed 55 line kilometers of induced polarization geophysical and ground magnetic surveying, along with a 355 hole, 2,988 meter auger drilling campaign.
Based on the results from the drilling, which aimed to confirm an identified gold anomaly in the topsoil, the anomaly is about 2.5 kilometers long and 500 to 800 meters wide, with an average grade of more than 20 parts per billion gold.
In the update, Starcore reported it established a field office during Q1 2025 and is completing a soil sampling program covering 5.5 square kilometers and 1,300 samples up to a depth of 1 meter.
Shares in Starcore reached a year-to-date high of C$0.325 on June 4.
5. Troilus Gold (TSX:TLG)
Year-to-date gain: 139.9 percent
Market cap: C$272.7 million
Share price: C$0.69
Troilus Gold is advancing its namesake property in Northern Québec, Canada.
The project is situated within the region covered by Plan Nord, a 25 year, C$80 billion development initiative focused on mining launched by the Government of Québec.
A May 2024 feasibility study revealed financials with a post-tax net present value of US$884.5 million, an internal rate of return of 14 percent and a payback period of 5.7 years based on a gold price of US$1,975 per ounce.
The included mineral resource estimate reports a probable mineral reserve of 6.02 million ounces of gold from 380 million metric tons of ore at an average grade of 0.49 g/t gold. It also hosts probable copper and silver reserves of 484 million pounds and 12.15 million ounces respectively.
Troilus has spent much of 2025 raising funds for the project's development. The most significant came on March 13, when the company announced that it executed a mandate letter for a non-binding term sheet for a debt financing package of up to US$700 million.
The company noted that it had followed up on four letters of intent, resulting in a total potential funding of up to US$1.3 billion.
More recently, Troilus announced on June 18 that it had entered into an offtake agreement for gold-copper concentrate with German smelting company Aurubis (OTC Pink:AIAGF,XETRA:NDA).
The agreement is being executed in connection with the previously announced letter of intent for US$700 million in funding. According to Troilus, this includes a loan guarantee of up to US$500 million from a firm representing the German Federal Ministry of Economic Affairs and Climate Action.
Shares in Troilus reached a year-to-date high of C$0.73 on June 17.
