Aris Mining lifts Segovia gold reserves to 1.92M oz
The reserve estimate was calculated using a US$2,800-per-ounce gold price, while the resource estimate used US$3,200 per ounce.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
Aris Mining Corporation increased Segovia’s proven and probable mineral reserves 28% to 1,920,000 ounces, effective November 10, 2026. The estimate reports 4,483,000 tonnes at a gold grade of 13.32 g/t, compared with 4,367,000 tonnes at 10.70 g/t in the November 28, 2025 estimate. The company said exploration and resource conversion more than offset mining depletion.
Aris Mining also reported 3,909,000 ounces of measured and indicated mineral resources and 2,623,000 ounces of inferred resources. Mineral resources are inclusive of mineral reserves; resources that are not reserves have no demonstrated economic viability. The reserve estimate used a gold price of US$2,800 per ounce.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

MINING INCREASES SEGOVIA GOLD RESERVES BY 28% TO 1.9 MILLION OUNCES
Exploration and resource conversion more than offset mining depletion,
expanding Segovia’s high-grade reserve base
Vancouver, Canada, November 10, 2026 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE: ARIS) has updated the Segovia mineral reserve and resource estimates, effective November 10, 2026. The new estimates demonstrate growth in contained gold reserves alongside increases in reserve and resource grades.
| ● | Proven and probable mineral reserves increased by 28% to 1.9 million ounces of gold (Moz), up from 1.5 Moz in the 2025 estimate1, with net growth of 418 koz after accounting for ounces mined during the period2. |
| ● | Measured and indicated mineral resources increased by 8% to 3.9 Moz, up from 3.6 Moz in the 2025 estimate; while inferred resources were 2.6 Moz, compared with 2.9 Moz previously2. This reflects the focus on infill drilling and the conversion of high-grade mineral resources to mineral reserves. |
| ● | Segovia continues to demonstrate exceptional gold grades. Proven and probable mineral reserve grades increased by 24% to 13.3 g/t Au, compared with 10.7 g/t Au previously, while measured and indicated mineral resource grades increased by 29% to 19.8 g/t Au, compared with 15.3 g/t Au2. |
Neil Woodyer, Chair and CEO of Aris Mining, commented “Mining in the Segovia district spans more than 150 years, yet exploration continues to add gold to the reserve base. The 28% increase in reserves demonstrates that our exploration and resource conversion programs are doing more than simply replacing ounces produced. The increase in both contained ounces and grades reinforces the strength of this exceptional high-grade operation and supports our objective of continuing to extend Segovia’s mine life.
Segovia’s cash generation also provides an important foundation for our broader growth strategy. At the same time, we are advancing significant milestones across our portfolio, including the Toroparu prefeasibility study targeted for release later this month and marking the first time Aris Mining declares a mineral reserve estimate for Toroparu, and an updated NI 43-101 technical report for Marmato expected in the first quarter of 2027, following first gold from the new CIP plant. Together, these initiatives reflect our focus on sustaining the performance of our producing mines while advancing our growth projects.”

● There are no known mining, legal, political, metallurgical, infrastructure, permitting, or other relevant factors that could materially affect the mineral reserve estimate. ● Totals may not add due to rounding. ● A gold price of US$2,800 per ounce was used for the 2026 and 2025 mineral reserve estimates, US$1,915 was used in 2024, and US$1,700 was used in 2023 and 2022. ● The 2026 mineral reserve estimate utilized a gold cut-off grade of between 3.22 g/t and 4.26 g/t depending on mineral reserve area. The cut-off grade values were applied to vein grades diluted to a minimum mining width that varies according to the mining area. ● The 2026 mineral reserve estimate was prepared by Aris Mining technical staff under the supervision of and reviewed by Ignacio Vélez, FAusIMM, Vice President Technical Services of Aris Mining, who is a Qualified Person as defined by NI 43-101. | |||||||||

3 Reflects expected steady-state annual gold production of approximately 300 thousand ounces (koz) at Segovia and 200 koz at Marmato following completion and ramp-up of the respective expansion projects. For more information, please refer to the Company’s news releases dated June 30, 2025 regarding the Segovia expansion and March 12, 2025 regarding the Marmato expansion.
4 Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment effective October 21, 2025, which contemplates a 7.0 Mtpa operation over a 21.3-year mine life with average annual gold production of approximately 235 koz at a base case gold price of US$3,000/oz. The preliminary economic assessment is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There can be no assurance that the projected production will be achieved. In the case of Soto Norte and Toroparu, such production also remains subject to obtaining all necessary permits and to formal construction decisions by the Company.
