Prominence Energy Jumps 33% on Helium; Adavale, Tasmea Gain

Prominence Energy (ASX:PRM) jumped 33.3% to 0.2¢ after satellite data flagged helium and natural hydrogen anomalies at its Eyre project. Adavale Resources (ASX:ADD) rose 2.86% to 3.6¢ as drill results extended the gold resource below the existing open pit. Tasmea (ASX:TEA) gained 4.43% to $9.43 on the acquisition of JPS Group, an integrated services provider to the energy sector. The ASX 200 was up 30.1 points by lunchtime, helped by a softer inflation print.

Prominence Energy's independent satellite spectral analysis identified numerous helium and natural hydrogen anomalies across the Eyre project. COO Krista Davies said the results support the company's exploration model and help advance high-priority targets toward drilling. The study adds to a growing body of evidence that the project hosts commercial-grade helium and hydrogen, though drilling remains the next catalyst.

Adavale Resources' latest results from the London-Victoria gold mine in New South Wales' Lachlan Fold Belt validated and extended the resource below the northern portion of the open pit. The company said the intercepts confirm structurally controlled higher-grade shoots and broader mineralised zones to the south. The mine is already in production, and the extension could lift mine life and throughput.

Tasmea's acquisition of JPS Group diversifies its earnings into LNG and gas infrastructure markets. Managing Director Stephen Young called the deal a defining step in the group's programmatic growth strategy. JPS provides maintenance, shutdowns, and project services to energy clients, adding a recurring revenue stream to Tasmea's existing trade skills portfolio.

On the macro side, the May CPI print came in at 4%, down from 4.2% in April and below consensus. The ABS attributed the easing to sharp falls in petrol and diesel prices. Housing remained the largest contributor, rising 6.5%. The data keeps the RBA on hold, with the next meeting in August.
