Pentanet (ASX:5GG)

Digital infrastructure company Pentanet drew significant attention after reporting a marked improvement in operating and financial performance in its FY26 business update.

Group revenue rose eight per cent on PcP1 to $24.4 million, while group EBITDA increased 74% to $2.4 million, reflecting improved profitability.

The company informed shareholders that rising gaming hardware costs have strengthened the value proposition for premium cloud-gaming through its CloudGG platform relative to individual hardware ownership. Cloud gaming services allow users to stream games from remote data centres, eliminating the need to purchase and periodically upgrade expensive local hardware—a model that has gained traction globally as GPU prices have climbed.

Managing Director Stephen Cornish noted that Pentanet is an NVIDIA GeForce NOW Alliance Partner in Australia and New Zealand, and that this NVIDIA relationship is becoming increasingly strategic. Pentanet's CloudGG premium cloud-gaming services run on NVIDIA GPUs, and the company owns one of Australia's largest clusters of high-powered NVIDIA gaming GPUs. The Alliance Partner status also grants Pentanet access to NVIDIA GPU infrastructure upgrades.

5GG shares rose 60% to 2.4¢ in morning trade.

Codrus Minerals (ASX:CDR)

Codrus Minerals shares jumped after the company announced it had reached an agreement to acquire two high-potential exploration assets in Australia and Peru, representing a growth and diversification opportunity in the copper, molybdenum, and critical minerals sector. Both copper and molybdenum are included on multiple governments' critical and strategic minerals lists due to their roles in electrification, infrastructure, and alloy manufacturing.

In Australia, the Copperhole Creek project comprises an exploration permit covering approximately 62 sq. km, located roughly 300km from Townsville and Cairns in Queensland. The project contains multiple prospects with a defined land position and significant historical exploration results that have not yet been followed up using modern exploration techniques.

In Peru, the Tiquihua project consists of a mining concession of approximately 100 hectares. The project has seen small-scale artisanal work and is considered prospective for high-quality molybdenum, copper, and other critical minerals. Peru is one of the world's largest copper producers and hosts a substantial portion of global molybdenum reserves.

Codrus confirmed it has received firm commitments from institutional, sophisticated, and professional investors to raise up to $2,500,000 through a two-tranche non-underwritten institutional placement.

CDR climbed 34.6% to 0.9¢ per share.

Hamelin Gold (ASX:HMG)

Hamelin Gold attracted strong interest after reporting further high-grade gold results from its maiden reverse circulation (RC) drill program at the Day Dawn gold project in the Paterson Province of Western Australia. The Paterson Province is a recognised mineral province that hosts the Telfer gold-copper mine, historically one of Australia's largest gold operations, and has been the focus of renewed exploration interest following major discoveries in the region.

Drilling identified two distinct high-grade lode positions at the Aurora prospect. New results from Altus, located 50m southeast of Aurora, confirmed the emergence of reef-style gold mineralisation that remains unconstrained.

"The identification of both multiple lodes at Aurora and the emergence of high-grade reef style mineralisation at Altus represents a major step forward in our understanding of the Day Dawn gold system," said Managing Director Peter Bewick.

"What initially appeared to be a pair of steeply dipping high-grade lodes is now developing into a broader mineralised corridor containing multiple gold-bearing structures. With mineralisation remaining open, numerous untested targets and diamond drilling planned to test the system at depth, we believe Day Dawn could rapidly evolve into a significant new gold discovery in the Paterson Province."

HMG gained 17.7% to 20¢.

Broader Market

The S&P/ASX 200 closed lower, declining 17.2 points, or 0.19%. The index's bottom-performing stocks were Elevra Lithium (ASX:ELV) and Iperionx (ASX:IPX), down 6.37% and 3.28% respectively. Over the trailing five days, the index has gained 0.74% and currently sits 2.64% below its 52-week high.

Critical Minerals and M&A Outlook

Beyond the local market, the expansion of electric vehicles, artificial intelligence, and alternative energy is driving a surge in dealmaking across critical minerals and rare earths, according to Andrew Timbers and Nicholas Smith, co-heads of metals and mining in the Americas at Goldman Sachs Global Banking & Markets.

Goldman Sachs highlighted that copper, lithium, and elements used in defence applications—such as tungsten and antimony—are essential to the functioning of these rapidly growing technologies, as are rare earth elements.

As demand accelerates, financial activity is intensifying, including mergers and acquisitions, initial public offerings, and U.S. government investment aimed at narrowing the supply-chain gap with China.

"Critical minerals now sit at the intersection of electrification, AI-driven power demand, and supply-chain security," said Mr. Timbers.
