Top 5 ASX Copper Stocks of 2025

1. Ausquest (ASX:AQD)

Year-to-date gain: 575 percent
Market cap: AU$72.38 million
Share price: AU$0.054

Ausquest is a mineral exploration company with polymetallic projects in Australia and Peru. In Australia, the company has a strategic alliance agreement with South32 (ASX:S32) that encompasses base metal projects across Western Australia and South Australia.

Ausquest's main focus in the first half of 2025 is its portfolio of copper-gold prospects along the southern coastal belt of Peru, which includes the Cangallo porphyry copper, Lantana and Playa Cali copper projects.

Shares of Ausquest started the year trading at AU$0.008, and soared after the company announced a major large-scale porphyry copper-gold discovery at Cangallo during its maiden drill campaign on the property on January 23. For example, hole CANRC001 returned an interval of 348 metres grading 0.26 percent copper and 0.06 parts per million (ppm) gold from 6 metres, including 26 metres at 0.36 percent copper and 0.07 ppm gold.

The company's share price reached AU$0.043 by January 28, and jumped even higher to AU$0.057 on February 6 after the company reported that further drill results confirmed the significance of the porphyry copper-gold discovery at Cangallo.

More recently, on June 12, Ausquest commenced Stage 2 of its drill campaign at Cangallo.

"The Stage 2 RC drilling program is designed to extend the original copper-gold intersections by re-directing drill-holes from the original drill pads as well as stepping out to the west, south and north to help locate the centre of the porphyry system(s)," the press release states.

Ausquest's share price hit a year-to-date high of AU$0.064 on June 20.

2. Kingston Resources (ASX:KSN)

Year-to-date gain: 94.44 percent
Market cap: AU$119.41 million
Share price: AU$0.14

Kingston Resources is working to establish itself as a mid-tier gold and base metals company with multiple production streams. Its flagship Mineral Hill gold and copper mine in New South Wales is currently producing gold and silver. The company is looking to begin copper concentrate production from the mine next year.

In early June, Kingston announced high-grade gold and copper intercepts confirming the growth potential at the project's Southern Ore Zone, which the company states "provide optionality to extend the underground mine plan and improve economic returns." Later in the month, the first gold concentrate production and sales in 10 years were achieved at the mine.

“With flotation successfully recommissioned, we now have full processing optionality — from gold doré and concentrate to separate copper, lead and zinc concentrates — and a clear pathway to underground mining. This is a pivotal step in unlocking long-term value and cash flow. We remain firmly on track for copper concentrate production by mid-2026, positioning FY26 as a breakout year for Kingston,” Managing Director and CEO Andrew Corbett stated in the press release.

3. Magmatic Resources (ASX:MAG)

Year-to-date gain: 87.5 percent
Market cap: AU$25.65 million
Share price: AU$0.06

Magmatic Resources is a copper and gold explorer in New South Wales, Australia, and its Myall, Wellington North and Parkes projects are located in the East Lachlan region of the state. This area is home to one of Australia’s largest gold and copper producing operations, Newmont’s (ASX:NEM,NYSE:NEM,TSX:NGT) Cadia East mine.

Magmatic has a farm-in and joint venture agreement with Fortescue (ASX:FMG) subsidiary FMG Resources on the Myall copper-gold project. Under the agreement, signed in March 2024, Fortescue may spend up to AU$6 million over four years to earn a 51 percent interest in the project, after which it may spend an additional AU$8 million to bring its stake in Myall to 75 percent. Fortescue is also a cornerstone investor in Magmatic Resources with a 19.9 percent stake.

On March 25 of this year, Magmatic announced partial results from the diamond drill program at Myall launched earlier in the year. Results from the hole drilled at its Calais target revealed the potential for a new copper-gold discovery, Magmatic reported, with an interval of 42.8 meters grading 0.19 percent copper and 0.03 g/t gold, including 10.8 metres at 0.39 percent copper and 0.07 g/t gold.

The company released the results for the remainder of the 12 hole drill program on June 6, including a follow-up diamond drill hole completed at the Calais target. Best assay results from this hole included 8 metres at 0.23 percent copper and 0.04 g/t gold within 26 meters at 0.14 percent copper and 0.08 g/t gold.

“The gold mineralisation intersected by recent drilling at Calais has continued to open up this second exploration front within the Myall FJVA Project and intersecting a gold-copper zone at this early stage is very encouraging. We are working closely with Fortescue on a follow-up program,” Managing Director David Richardson stated.

Magmatic’s share price hit a year-to-date high on July 4, coming in at AU$0.06 per share.

4. Revolver Resources (ASX:RRR)

Year-to-date gain: 37.93 percent
Market cap: AU$11.05 million
Share price: AU$0.04

Revolver Resources has two wholly owned copper projects in Queensland, Australia: Dianne and Osprey. At both of these projects, the company is targeting Mount Isa style copper and IOCG deposits.

Revolver is advancing toward a final investment decision on bringing the Dianne copper mine into production. So far this year, it has reached some key milestones toward that end, giving its share price a boost.

In February, the company announced that it had finalised the SX/EW process front-end engineering design, a critical technical milestone required for the AU$1.3 million grant awarded by the Queensland Critical Minerals and Battery Technology Fund the previous year.

In preparation for a restart of production at Dianne, Revolver launched a diamond drill program in mid-June. The following week, the company announced it had completed the site engineering design, the final requirement needed to satisfy the scope of work outlined in the grant, and as such received the remainder of the grant funding.

Revolver’s share price hit a year-to-date high of AU$0.04 on July 7. The company is targeting a restart of mining activities at Dianne in the second half of 2025 with first copper cathode production slated for the first half of 2026.

5. Carnaby Resources (ASX:CNB)

Year-to-date gain: 21.43 percent
Market cap: AU$98.21 million
Share price: AU$0.425

Carnaby Resources is advancing its Greater Duchess copper-gold project in Queensland, which hosts several IOCG deposits. The company has secured binding tolling and offtake agreements with Glencore (LSE:GLEN,OTC Pink:GLCNF).

Carnaby has had a substantial amount of positive newsflow out of Greater Duchess so far in 2025, much of it coming from its ongoing work towards a pre-feasibility study (PFS) for the project, which is slated for completion in the second half of this year.

In February, the company highlighted significant drill results from its PFS related work on the property, including 12.2 metres at 6.8 percent copper and 1.8 g/t gold at the Mount Hope target.

In mid-April, Carnaby announced that the Queensland government awarded the project two grants totaling AU$386,000. Later in the month, the company kicked off a drill campaign at the Trekelano copper-gold project with results intended to be included in the Greater Duchess PFS as a source of mineral resource growth.

The company's share price has trended upwards since May, during which time Carnaby has released multiple rounds of assays from its Trekelano drill campaign. The first results came on May 27 and included assays of 41 metres at 2.3 percent copper and 0.5 g/t gold. Subsequent reports highlighted broad intervals of mineralisation at the project, including 164 metres at 0.4 percent copper and 0.2 g/t gold on June 25 and 154 meters at 0.9 percent copper and 0.2 g/t gold on July 9.

Shares in Carnaby Resources reached a year-to-date high of AU$0.45 on July 3.
