The S&P/ASX 200 Index (ASX: XJO) is fighting hard to start the week positively. In afternoon trade, the benchmark index is up a fraction to 7,935.5 points.
Four ASX shares that are rising more than most today are listed below. Here's why they are climbing:
Amplitude Energy Ltd (ASX: AEL)
The Amplitude Energy share price is up over 2% to 22.5 cents. This morning, the Australian gas production company formerly known as Cooper Energy announced a binding joint venture with O.G. Energy. According to the release, the two parties have entered into joint venture arrangements to progress the East Coast Supply Project (ECSP) on a 50/50 basis to deliver additional gas supply to the structurally short East Coast market. Management notes that the first gas supplied from the ECSP is targeted in 2028, utilising existing brownfield infrastructure. This will help mitigate expected shortfalls in the market while supporting energy security for Australian customers.
Catapult Group International Ltd (ASX: CAT)
The Catapult Group share price is up 3% to $3.62. This could have been driven by the sports technology company's shares being added to the S&P/ASX 300 Index this morning following the quarterly rebalance. When this happens, it means funds that track the index, such as the popular Vanguard Australian Shares Index ETF (ASX: VAS), need to buy shares to reflect the change.
Gorilla Gold Mines Ltd (ASX: GG8)
The Gorilla Gold Mines share price is up 6% to 42.5 cents. This morning, the gold miner formerly known as Labyrinth Resources returned to trade after securing firm commitments for a $25 million institutional placement. Management advised that it was supported by leading domestic and international resource investors. The funds are being raised at $0.38 per share, which represents a discount of 5% to its last close price. The company notes that this leaves it in an "excellent position to accelerate exploration at our very exciting Lakeview discovery."
Mineral Resources Ltd (ASX: MIN)
The Mineral Resources share price is up 5% to $23.95. This follows news that haulage operations resumed on the Onslow Iron dedicated haul road on 21 March 2025. The resumption followed constructive discussions with WorkSafe WA regarding controls and risk mitigation. The previously announced works program to upgrade the haul road continues on schedule for completion in the first quarter of FY 2026. Management advised that transhipper four, MinRes Rosily, also commenced operations at the Port of Ashburton on 22 March. This increases Onslow Iron's transhipping capacity to 28 million tonnes per annum.
