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.

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.

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.

Exploration at the project is currently ongoing. Noble raised AU$3 million in September 2024, with proceeds allotted for North Rukwa and North Nyasa.

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.

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).
