29Metals Ltd (ASX: 29M)
The 29Metals share price is down 32% to 25.2 cents. Investors have been selling this copper producer's shares following the release of an update on its progress to reestablish mining at the Xantho Extended orebody at the Golden Grove operation in Western Australia. It advised that based on a new assessment, additional works to further reduce the risk of future potential production interruptions will be needed prior to recommencement of mining. And while there is no change to its copper production guidance for FY 2026, it has downgraded its guidance for zinc, gold, and silver materially.
DGL Group Ltd (ASX: DGL)
The DGL Group share price is down 25% to 40 cents. This has been driven by the release of the chemicals logistics and services supplier's half-year update. DGL Group reported a 5.8% decline in sales revenue to $225 million, a 5% decline in underlying EBITDA to $24.7 million, and a statutory loss after tax of $12.8 million. It notes that its revenue was impacted by ongoing scarcity in used lead acid batteries due to illegal exports.
Fletcher Building Ltd (ASX: FBU)
The Fletcher Building share price is down 1% to $2.44. This morning, the building products company released a quarterly sales update and revealed improvements in volumes. Fletcher Building's CEO, Andrew Reding, said: "Quarterly volumes for the March quarter continued to show early signs of improvement across the portfolio, with the important caveat that this quarter largely preceded the current geopolitical escalation." One negative was the company warning that the "overall impact of the Middle East crisis on the Group's financial performance, including for the FY26 year, cannot be ascertained with certainty at this time."
Newmont Corporation (ASX: NEM)
The Newmont share price is down 5% to $156.82. This is despite there being no news out of the gold miner today. However, it is worth noting that most ASX gold stocks are under pressure today. This has led to S&P/ASX All Ordinaries Gold index falling 2.15% this afternoon.
