Aris Mining Corporation (TSX: ARIS) (NYSE-A: ARMN) announces gold production results of 53,608 ounces (oz) for Q3 2024, with 47,493 oz from Segovia and 6,115 oz from the Marmato Upper Mine. This represents a 9% increase over total gold production in Q2 2024. Additionally, the Company has made significant progress on expansion projects at Segovia and has updated mineral resource and mineral reserve estimates with an effective date of July 31, 2024. At the Marmato Lower Mine, construction is advancing on schedule and has crossed the 25% spend threshold.
Neil Woodyer, CEO of Aris Mining, commented “We are pleased to share the continued progress of our Segovia and Marmato expansion projects, which position Aris Mining to achieve an annual gold production rate of approximately 500,000 oz in the second half of 2026. The first phase of the Segovia Expansion, which includes an expanded receiving area for mill feed from our mining partners, has been successfully commissioned. Phase 2 of the Segovia Expansion is underway and is on track for completion in Q1 2025. Following completion and ramp-up, Segovia’s gold production is expected to exceed 300,000 oz per year. This growth is driven by a focused exploration strategy that has consistently increased gold resources and replaced gold reserves. Additionally, construction of the Marmato Lower Mine remains on schedule, and we continue to advance the studies for the redesigned and smaller environmental footprint Soto Norte project for early 2025.”
Segovia – Expansion updates
Phase 1 of the Segovia expansion is complete with the newly expanded receiving area for our contract mining partners (CMPs) fully commissioned and being handed over to operations. The expanded receiving area enhances mill feed capacity and operational efficiencies. Phase 2, which involves installing a second ball mill in the former contractor receiving area, is underway and scheduled for completion in Q1 2025. The new ball mill will increase throughput and enable finer grinding, process efficiency and gold production.
Gold production from Segovia in Q3 2024 totaled 47,493 oz, reflecting a 9% increase over Q2 2024. With the expansion ramp-up in mind, Aris Mining is targeting gold production from Segovia of 185,000 to 195,000 oz in 2024, 250,000 oz in 2025 and over 300,000 oz in 2026.
Segovia – Updated Mineral Resource and Mineral Reserve Estimates
As announced in our August 2024 exploration drilling results news release1, Segovia’s exploration programs continue to deliver high-grade intersections. These results are included in updated estimates effective July 31, 2024, resulting in growth of the mineral resources and full replacement of the mineral reserves (see Figures 1 and 2 below). These new estimates build on the strong growth in 2023 and support the ongoing Segovia expansion project. The 2025 drilling program is expected to focus on these newly identified near-mine mineral resources, aiming to convert them into mineral reserves with low development costs.

Marmato expansion updates
The Marmato Lower Mine expansion is progressing on schedule, with the site access road and portal face now complete and the contractor preparing to initiate work on the twin declines. Both the SAG and ball mill fabrication are progressing on schedule for completion before the end of 2024. Annual gold production from the Marmato Upper and Lower mines is expected to grow to an average of 162,000 ounces over a 20-year mine life once the Lower Mine is operational3.
As of September 30, 2024, the project reached the “25% spend” milestone required for the first milestone payment under the precious metals purchase agreement with Wheaton Precious Metals (WPMI). WPMI has been notified, and the US$40 million first milestone payment is expected to be received before the end of the month, with additional US$40 million and US$42 million payments at the 50% and 75% spend milestones, respectively.

About Aris Mining
Aris Mining is a gold producer in the Americas, currently operating two mines with expansions underway in Colombia. The Segovia Operations and the Marmato Upper Mine produced 226,000 ounces of gold in 2023. Aris Mining is targeting a production rate of approximately 500,000 ounces of gold per year in the second half of 2026, following a ramp-up period after the Segovia mill expansion scheduled for completion in Q1 2025 and the Marmato Lower Mine’s first gold pour in late 2025. Aris Mining also operates the 51% owned Soto Norte joint venture, where studies are underway on a new, smaller scale development plan, with results expected in early 2025. In Guyana, Aris Mining is advancing Toroparu, a gold/copper project. Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification.
Aris Mining promotes the formalization of traditional miners into contract mining partners as this process enables all miners to operate in a legal, safe and responsible manner that protects them and the environment.
