Catalyst Metals Ltd (ASX: CYL)
The Catalyst Metals share price is down 5.5% to $5.71. This follows the release of the gold miner's quarterly update. Catalyst reported gold production of 26,127 ounces with an all-in sustaining cost (AISC) of A$2,901 per ounce. Looking ahead, while the gold miner has reaffirmed its production guidance of 100,000 ounces to 110,000 ounces, it has lifted its cost guidance. It now expects its FY 2026 AISC to come in at A$2,750 per ounce to A$2,950 per ounce. This compares to its previous guidance range of A$2,200 per ounce to A$2,650 per ounce. This reflects processing plant downtime, lower material movements, and broader inflationary pressures such as rising diesel costs.
G8 Education Ltd (ASX: GEM)
The G8 Education share price is down 30% to 16.7 cents. Investors have been selling this childcare operator's shares following the release of a trading update. Management advised that occupancy across the sector is lower compared to 2024 and 2025. This is due to families experiencing sustained affordability pressures, falling birth rates, increased long-day care supply, and confidence being impacted by serious child safety incidents. At the same time, operators are dealing with increased costs due to inflationary pressures, persistent workforce challenges, changing regulation and compliance requirements, and a more complex operating environment. Current occupancy stands at 56.4%, which is down 7% versus the prior corresponding period.
Meteoric Resources NL (ASX: MEI)
The Meteoric Resources share price is down 6.5% to 18.7 cents. This morning, the rare earths developer announced the completion of a $40 million placement to institutional and sophisticated investors. Meteoric Resources raised the funds through the issue of 235 million shares at 17 cents per new share. The placement will fund the advancement and pre-development activities for the 100%-owned Caldeira Rare Earth Iconic Absorption Clay Project towards a final investment decision.
Westgold Resources Ltd (ASX: WGX)
The Westgold Resources share price is down 3% to $5.92. This follows the release of the gold miner's quarterly update. Westgold reported production of 93,145 ounces of gold, which was down 16.4% quarter-on-quarter from 111,418 ounces. And while it has reaffirmed its production guidance, it expects costs to be at the high-end of its guidance range.
