ARIS MINING CLOSES ACQUISITION OF REMAINING 49% OF SOTO NORTE
Vancouver, Canada, December 12, 2025 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE -
A: ARMN) announces the completion of its previously announced acquisition of the remaining 49% interest in the
Soto Norte joint venture in Colombia from MDC Industry Holding Company LLC (Mubadala). Aris Mining now owns
100% of the Soto Norte Project, and the associated precious metals stream previously granted to Mubadala has been
terminated.
Neil Woodyer, CEO of Aris Mining, commented: “ With 100% ownership of Segovia, Marmato, Toroparu, and now
Soto Norte, Aris Mining is focused on building a large, diversified gold business across Colombia and Guyana. Our
strategy combines strong cash flow generation from our operating mines with growth from expansions, exploration,
and project development.
Since our formation in 2022, we have progressed from a ‘buy -and-build’ strategy to focusing on building the high-
quality assets we now own. Fewer than 15 gold companies worldwide produce more than one million ounces
annually — and with our current asset base and growth projects, Aris Mining has a clear path to join that group1.”
About Aris Mining
Founded in September 2022, Aris Mining was established with a vision to build a leading South America-focused gold
mining company. Our strategy blends current production and cashflow generation with transformational growth
driven by expansions of our operating assets, exploration, and development projects. Aris Mining intends to unlock
value through scale and diversification. The Company is listed on the TSX (ARIS) and the NYSE -A (ARMN) and is led
by an experienced team with a track record of value creation, operational excellence, financial discipline and good
corporate governance in the gold mining industry.
Aris Mining operates two underground gold mines in Colombia: the Segovia Operations and the Marmato Complex,
which together produced 210,955 ounces of gold in 2024. With expansions underway, Aris Mining is targeting an
annual production rate of more than 500,000 ounces of gold, driven by the commissioning of a second mill at Segovia,
completed in June and ramping up during H2 2025, and the construction of the Bulk Mining Zone at the Marmato
Complex, with first gold expected in H2 2026.
In Guyana, Aris Mining owns the Toroparu gold project, where a new Preliminary Economic Assessment has been
completed and a Prefeasibility Study is in progress. Following completion of the PFS, Toroparu will be positioned to
advance toward construction.
Aris Mining also owns the Soto Norte gold project, where a Prefeasibility Study has been completed on a smaller -
scale development plan confirming Soto Norte as a high-grade, long-life project with strong economics and industry-
leading environmental and social design features. Environmental studies are being finalized, which are scheduled to
be submitted in the first half of 2026 to initiate the licensing process.

1 Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment and is preliminary in nature. It
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. Such production also remains subject to obtaining all necessary permits for both Soto Norte and Toroparu.
