Northern Star Resources shares climbed 4% to A$20.69 after U.S. activist investor Elliott disclosed a long position via cash-settled equity swaps covering 76,194,999 shares, worth more than A$1.5 billion at the current price. Elliott has been pressing for board renewal and a broader strategic review, adding to focus on the miner’s outlook. The company reported FY26 gold sold of 1.543 million ounces, below the lower end of its revised guidance. Gold futures rose about 0.5% to US$4,070.80 an ounce, supporting sentiment across the sector.

Capricorn Metals (ASX: CMM) said its group gold ore reserves rose 33% to 5.24 million ounces and released an updated prefeasibility study for the Mt Gibson project. The study outlined a 19-year production profile averaging 190,000 ounces a year, with output of 260,000 ounces a year over the first four full years, and projected pretax free cash flow of $12 billion. The company also lifted its medium-term production guidance to 400,000 ounces per year and set a longer-term target of 500,000 ounces per year. The update pushed CMM shares up 15.1% on Monday, outperforming the ASX 200.

Myer Ltd reported FY26 total sales of $4.089 billion, up 11.3% year on year, but pro forma sales rose just 0.3% after integrating the former Premier Investments apparel brands it bought in early 2025. The retailer said it expects full-year operating gross profit of about $1.601 to $1.607 billion, up about 13.8% to 14.3% on an actual basis but down about 2.1% to 2.5% on a pro forma basis. It attributed the pro forma decline to higher-than-planned promotional activity as consumer demand weakened.

Evolution Mining (ASX: EVN) said it will acquire copper and gold miner Carnaby Resources (ASX: CNB) in an all-share deal valuing Carnaby at around A$213 million. Carnaby shareholders are set to receive 0.0682 new Evolution shares for each Carnaby share held, giving an implied offer price of 77 cents per share based on Friday’s close. The transaction includes Carnaby’s copper-rich Greater Duchess Project in Queensland, which Evolution plans to fold into its nearby Ernest Henry operations to add 10,000 tonnes of copper production per year using existing infrastructure. Carnaby’s board has unanimously recommended the scheme, which remains subject to customary closing condition.

Electro Optic Systems (ASX: EOS) said first-half 2026 revenue rose 284% year on year to approximately $169 million. Its order book climbed 84% to a record $846 million. The company pointed to major new defence contracts, including a ~$175 million counter-drone systems order and a ~$23 million Middle East naval remote weapon systems deal. It also lifted FY26 base-business revenue guidance to $280–$300 million.

Australian Foundation Investment Company (AFIC, ASX: AFI) reported FY26 net profit up 3% to A$293.5 million, but its portfolio delivered a total return of just 0.9% including franking credits. That compared with a 7.2% gain for the S&P/ASX 200 Accumulation Index, leaving AFIC well behind the broader market. Net tangible assets per share fell to A$7.93 from A$8.33, while the shares slid 8% over the year. AFIC kept its full-year dividend at 31.5 cents per share and declared a 2.5 cents per share special dividend.

Metals X (ASX: MLX) reported quarterly imputed revenue of $207.40 million, up 3%, as higher tin prices lifted earnings. Imputed EBITDA rose to $125.91 million even as tin output edged lower. The company ended the quarter with cash and equivalents of $374.00 million. It maintained guidance for the Renison resource update and progress on engineering for the Rentails project, while continuing to position for tin and related base-metals opportunities.

Xero (ASX: XRO) fell 2.8% intraday to A$62.63, its lowest level since June 2022, leaving the stock down 65% year to date. The slide came as tensions in the Middle East pushed Brent crude back above US$100 a barrel, reviving inflation and rate-hike worries. The risk-off move weighed on global tech stocks, with the S&P 500 technology sector and the ASX tech index also posting sharp declines.

Newmont reported June-quarter sales of US$6,118 million and net income attributable to shareholders of US$2,202 million, or US$2.06 per diluted share, sharply higher year on year. The company said the result was supported by a higher average realised gold price of US$4,414 per ounce, which helped offset lower quarterly gold production of 1.2 million ounces and higher all-in sustaining costs of US$1,938 per ounce. Free cash flow for the half year was US$5,349 million, and Newmont ended the quarter with US$9,009 million in cash. It also declared a quarterly dividend of US26c per share and continued stock repurchases.
