In January 2026, Minaurum announced its inaugural mineral-resource estimate of 5.37 million tonnes containing 55.2 million ounces of silver equivalent grading 320 g/t AgEq or 202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead, and 2.01% zinc. The resource contains 34.8 million ounces of silver, 35,640 ounces of gold, 51.0 million pounds of copper, 115 million pounds of lead, and 238 million pounds of zinc. The supporting NI43-101 technical report was filed on February 27, 2026, and included 104 drill holes, totaling 35,888.15 metres and 10,194 samples. Minaurum launched a 50,000-metre, six-rig core-drilling campaign in December 2025 as part of its ongoing resource-expansion program. The updated mineral-resource estimate will incorporate new data from the Europa, Promontorio, and Travesia vein zones, as well as additional vein zones including Europa Sur, Quintera and San Jose.

EraNova Produces 50 Oz Silver Bar From Silver Surprise Mini-Bulk Sample at Local Atlin Facility(TSXV: NOVA) (OTCQB: STXPF) EraNova Metals Inc. announced the successful production of a 50 oz refined silver bar from the remaining tailings generated during metallurgical testing of the Company's previously announced 1,585 lb (719 kg) surface mini-bulk sample collected from the Silver Surprise zone at its 100%-owned Ruby Creek Property near Atlin, British Columbia. The 50 oz refined silver bar was produced by Rino Mihoc of Ruby Gold Ltd. at his processing facility in Atlin, British Columbia, located approximately 20 kilometres from the Ruby Creek Property. Metallurgical testing of the Silver Surprise mini-bulk sample demonstrated 95% silver recovery through direct smelting and previously resulted in the production of an initial 445 g (14.3 oz) refined silver bar from gravity concentrate. Previous surface sampling at the Silver Surprise Zone returned assays of up to 16,030 g/t silver, including 28 samples exceeding 1,000 g/t silver and four samples exceeding 10,000 g/t silver. The Ruby Creek Property is a 29,700-hectare land package near Atlin, BC, hosting both the Adanac Molybdenum Project and the Atlin Discovery Project. The company projects the advancement of the Adanac Molybdenum Project toward a NI 43-101 compliant Preliminary Economic Assessment and ongoing exploration across the Ruby Creek district.
