ASX 200 gold stock slides on rising costs
Investors are bidding down the Regis Resources share price today following the release of the miner's June quarter update.
The ASX 200 gold stock reported gold production for the three months of 87,400 ounces at an all-in sustaining cost (AISC) of $2,812 an ounce. AISC in the quarter was materially higher than the $2,538/oz reported in the prior quarter.
Gold sales came in at 96,800 ounces bringing in $498 million in revenue. Regis achieved an average realised price of $5,148 an ounce, spurring operating cash flow of $260 million.
On the cost front, capital expenditure was $103 million for the quarter.
For the full FY 2025, Regis Resources produced 373,000 ounces of gold, near the high end of its guidance range. With an AISC of $2,531 per ounce, costs were in the bottom half of the miner's full-year guidance range, while rising in the June quarter.
As at 30 June, the company held cash and bullion of $517 million. That's up $222 million over the full year, and it's after the $300 million debt repayment made in January.
Commenting on the results that have yet to lift the ASX 200 gold stock today, Regis Resources CEO Jim Beyer said, "The team has delivered another strong quarter and exceeded our plans for the full 2025 financial year."
Beyer added:
This solid operational performance, combined with the supportive gold price environment, has strengthened our financial position over the year. With our FY26 guidance we expect this performance trend to continue.
Overall, Regis continues to build on its very strong position by reinvesting into both low-risk growth and opportunistic production, all the while growing balance sheet strength and long-term optionality.
What else did Regis Resources report today?
Separately, the ASX 200 gold stock announced this morning that it has agreed to acquire the Southern Star prospect from Great Southern Mining Ltd (ASX: GSN). Regis said it expects to define a project to convert mineralisation to another production source within six months.
Regis Resources will make a $4 million upfront cash payment, and contingent payments up to $5 million for the prospect.
Great Southern Mining's managing director, Matthew Keane, said: "This transaction is beneficial for both Great Southern Mining and Regis."
He added:
Regis is perfectly positioned to leverage the near-term development upside from Southern Star. It's a deal that creates immediate value and sets the stage for new discoveries in the Duketon Belt.
