Core Viewpoint - Aris Mining Corporation has updated its Segovia mineral reserve and resource estimates, showing significant increases in both measured and indicated resources as well as proven and probable reserves, indicating strong asset performance and long-term value creation potential for the company [2][7]. Mineral Resource Estimates - Measured and indicated resources increased by 7% to 3.6 million ounces (Moz) from 3.4 Moz in the 2024 estimate [7]. - Inferred resources grew by 12% to 2.9 Moz, reflecting ongoing exploration success [7]. - The average grade of measured and indicated resources is 15.3 grams per tonne (g/t) of gold [7]. Mineral Reserve Estimates - Proven and probable reserves increased by 12% to 1.5 Moz, up from 1.3 Moz in the 2024 estimate [7]. - The average grade of proven and probable reserves is 10.7 g/t of gold [7]. - The company utilized a gold price of $2,800 per ounce for the 2025 mineral reserve estimate, compared to $1,915 per ounce for the 2024 estimate [11]. Sensitivity Analysis - A sensitivity analysis was conducted across a range of gold prices from $2,100 to $3,200 per ounce, demonstrating that the Segovia mineral resource is largely insensitive to gold price assumptions [3]. - The analysis shows that measured and indicated contained gold ranges from 3.4 Moz to 3.6 Moz, highlighting the high-grade nature of the deposit [3]. Operational Context - Aris Mining operates two underground gold mines in Colombia, with a target annual production rate of over 500,000 ounces of gold following recent expansions [17]. - The company is also advancing other projects, including the Toroparu gold project in Guyana and the Soto Norte project, which are expected to contribute to future growth [18][19].

Core Viewpoint - Austral Gold Limited announced an updated Mineral Reserve and Resource Estimate for its Casposo Mine in Argentina, indicating a positive outlook for advancing the project towards renewed production [2][4][5]. Group 1: Mineral Reserve and Resource Estimates - Proven and Probable Mineral Reserves for the Casposo Mine are estimated at 2.149 million tonnes (Mt) with a grade of 1.31 g/t Au and 58.52 g/t Ag, containing approximately 80,000 ounces (Koz) of recoverable gold and 3.276 million ounces of silver [4][6]. - Measured and Indicated Mineral Resources are estimated at 2.258 Mt with a grade of 1.48 g/t Au and 59.91 g/t Ag [4][6]. - Inferred Mineral Resources are approximately 0.173 Mt with a grade of 7.52 g/t Au and 68.54 g/t Ag [4][6]. Group 2: Financial Metrics - The After-Tax Net Present Value (NPV) at an 11.8% discount rate is US$72.7 million, based on a gold price of US$2,855 per ounce [4][6]. - Undiscounted pre-tax free cash flows are projected at US$137.9 million, with post-tax cash flows of US$92.7 million [4][6]. - The All-in Sustaining Cost (AISC) is estimated at US$1,695 per ounce of gold [4][6]. Group 3: Production and Operational Details - The mine life is projected to be 74 months based on Mineral Reserves, with an estimated annual average production of 11,495 ounces of gold and 468,434 ounces of silver [4][6]. - Life of mine capital expenditures total US$10.8 million, primarily for sustaining capital related to reprocessing mineralized material and closure costs [4][6]. - Average operating costs over the life of the mine are estimated at US$85 per tonne milled or US$1,517 per gold equivalent ounce [4][6]. Group 4: Market Context - The announcement comes at a time when gold and silver prices are robust, which enhances the project's economic viability [5][6]. - The updated estimates are based on infill drilling and exploration activities conducted since the last technical report filed on June 30, 2016 [6].
