The Quality Premium: Why High-Grade Gold Districts are Driving a 2026 Institutional Re-Rating
Aris Mining executes the "1 Million Ounce" playbook through reserve expansion and jurisdictional de-risking.
The most recent material news release for Aris Mining (January 8, 2026) reports a significant expansion of mineral reserves and resources at the Segovia Operations in Colombia. Proven and Probable (P&P) reserves increased by 12% to 1.5 million ounces (Moz) of gold, even after accounting for mining depletion. Crucially, the reserve grade remains exceptionally high at 10.7 g/t Au. Measured and Indicated (M&I) resources grew by 7% to 3.6 Moz at 15.3 g/t Au. This update follows a sequence of strategic milestones in late 2025, including the settlement of a long-standing ICSID arbitration with the Colombian government (November 19, 2025) and the acquisition of the remaining 49% interest in the Soto Norte project (December 12, 2025).
- Reserve Replacement and Growth: Adding 160,000 ounces net of depletion at a 10.7 g/t grade confirms that Segovia remains one of the highest-grade gold mines globally. This supports the company’s plan to sustain higher production rates following the 2025 mill expansion to 3,000 tpd.
- Jurisdictional De-risking: The November 2025 settlement with the Republic of Colombia is a major pivot. It replaces adversarial arbitration with a 10-year collaborative framework, significantly lowering the "political risk discount" that has historically plagued Colombian assets.
- Path to 1 Moz/year: By moving to 100% ownership of Soto Norte and Toroparu, alongside the ongoing Marmato Bulk Mining Zone construction, Aris has solidified a clear organic path to intermediate producer status.
- Gold Price Sensitivity: The reserve calculation uses a gold price assumption of $2,800/oz. While this reflects current market strength, it is aggressive compared to the $1,400-$1,600/oz levels used by senior peers. A significant correction in gold prices would likely result in a sharp downward revision of these reserves.
Aris Mining is a mid-tier gold producer focused on Latin America. Its flagship asset is the Segovia Operations in Antioquia, Colombia, which has been in production for over 150 years. Segovia is unique for its high-grade nature (10+ g/t) and its hybrid mining model, combining owner-operated mining with a formalized contract mining partner (CMP) program. The company also operates the Marmato mine and is developing two world-class projects: Soto Norte (Colombia) and Toroparu (Guyana).
