Aris Mining Corporation reports developments from a Canadian gold mining company focused on South America. The company operates the Segovia and Marmato underground gold mines in Colombia and holds growth projects including Soto Norte in Colombia and Toroparu in Guyana. Its shares trade on the Toronto Stock Exchange and the New York Stock Exchange under the symbol ARIS.
Recurring news includes gold production, sales and revenue updates; quarterly and annual financial results; operating performance at Segovia and Marmato; and construction progress tied to the Marmato expansion, including underground access and plant infrastructure. Company announcements also cover project advancement, technical studies, annual meeting voting results, auditor appointment matters, and equity compensation plans such as restricted share units, performance share units and stock options.
Aris Mining (ARIS) completed a prefeasibility study outlining planned production of 5.6 million ounces of gold at Toroparu in Guyana. The plan spans 29 years, with average annual gold production of 258,000 ounces during years 1–17. Proven and probable gold reserves total 5.9 million ounces, estimated using $1,950/oz gold.
At base-case prices of $3,600/oz gold, $50/oz silver and $5.00/lb copper, estimated after-tax net present value at a 5% discount rate is $2.8 billion, with a 31.5% internal rate of return. Initial funding required is $1,005 million, after a $138 million offset from historic stream financing that Wheaton may elect to provide. Estimated lifetime all-in sustaining costs are $1,494/oz gold, net of by-product credits. Aris targets a construction decision in early 2027, subject to the mining licence and other necessary approvals; planned construction takes 32 months. All dollar amounts are U.S. dollars.
Aris Mining (ARIS) increased Segovia’s proven and probable gold reserves by 28% in its updated mineral estimates effective November 10, 2026. Reserves reached 1.9 million ounces, versus 1.5 million in the 2025 estimate, after accounting for mining depletion. Reserve grades rose 24% to 13.3 grams of gold per tonne, from 10.7.
Measured and indicated resources increased 8% to 3.9 million ounces, with grades rising 29% to 19.8 grams per tonne from 15.3. Inferred resources fell to 2.6 million ounces from 2.9 million, reflecting the focus on infill drilling and converting high-grade resources to reserves. Resources include reserves and are not additional ounces.
The company targets a Toroparu prefeasibility study later in November, including its first reserve estimate for that project, and expects an updated Marmato technical report in the first quarter of 2027 following first gold from the new CIP plant.
Aris Mining (ARIS) reported third-quarter 2026 adjusted EBITDA of $144 million, alongside higher year-to-date gold production and earnings than a year earlier. Quarterly gold revenue was $287 million, and net earnings were $67 million, or $0.32 per share, versus $94 million, or $0.46, in Q2. Year-to-date production rose 16% to 217.3 thousand ounces; adjusted EBITDA increased 81% to $535 million.
Cash totaled $419 million at September 30 after $144 million of quarterly capital investment. Aris targets the lower end of its 300,000–350,000-ounce 2026 production guidance. Marmato's new processing plant is commissioning, with first gold expected in December 2026 and full design capacity targeted by end-2027, following commissioning of its paste backfill plant. Toroparu's prefeasibility study is targeted for November 2026, ahead of assessment of a potential construction decision in early 2027.
Aris Mining (TSX: ARIS; NYSE: ARIS) will release its third-quarter 2026 financial results after market close on November 4, 2026. A conference call to discuss the results will take place that day at 3:00 pm Vancouver time (5:00 pm ET / 10:00 pm GMT). A replay will be archived on the company’s financials webpage.
Aris Mining (ARIS) reported nine-month gold production of 217.3 thousand ounces, an increase from the same period in 2025. Production rose 16.4% year over year, while third-quarter output was 69.3 thousand ounces versus 73.7 thousand in Q2. The company expects production at the lower end of its 300,000–350,000-ounce 2026 guidance. Q3 gold sales generated approximately $287 million at an average realized price of approximately $4,204 per ounce; year-to-date gold revenue exceeded $972 million.
Marmato commissioned its Cascabel 3 filtered tailings facility. Approximately four weeks of planned flotation plant downtime contributed to lower Q3 production, while upgrades increased capacity to 1,250 tonnes per day. Aris expects first gold from the new 5,000-tonne-per-day plant in Q4 2026 and approximately 500,000 ounces of annual production from the Segovia and Marmato expansions once fully ramped up.
Aris Mining (ARIS) completed preparation of Soto Norte’s Environmental and Social Impact Assessment and will begin community engagement before seeking environmental licensing. Meetings in Matanza, Suratá and California are scheduled for October, with relevant feedback considered before submission.
The technical mine plan was approved on July 29, 2026, but construction and mining require an environmental license. The La Baja permanent reserve was revoked, and the Temporary Reserve Area’s expiry reverted to March 4, 2027. The 2026 partial Santurbán Páramo delimitation was also revoked; existing protections remain effective while a new delimitation proceeds.
Soto Norte has 4.6 million ounces of gold reserves at 7.0 grams per tonne and an initial 22-year mine life. Aris Mining estimates owner-mined gold production averaging approximately 203,000 ounces annually over years 1–21. A construction decision would follow receipt of the environmental license.
Aris Mining (TSX: ARIS; NYSE: ARIS) congratulated Founder, Chair and CEO Neil Woodyer on his selection for the Canadian Mining Hall of Fame. His formal induction will take place at the Annual Dinner & Induction Ceremony in Toronto on January 14, 2027.

He later built Aris Gold and led its combination with GCM Mining to create Aris Mining in 2022. Fellow Hall of Fame members and Aris Mining shareholders Ian Telfer and Frank Giustra welcomed his recognition.
