Aris Mining Corporation (Aris Mining) operates as a gold mining company.
Aris Mining operates two underground gold mines in Colombia: the Segovia Operations and the Upper Mine, which together produced 210,955 ounces of gold in 2024.
With expansions underway, Aris Mining is targeting annual production of approximately 500,000 ounces of gold following the ramp up of the Segovia mill expansion, which is expected to be complete during the second half of 2025, and the new Lower Mine, which is expected to reach full production in 2026. In addition, Aris Mining operates the 51% owned Soto Norte joint venture, where studies are underway on a new, smaller scale development plan, with results expected in mid-2025. In Guyana, Aris Mining owns the Toroparu Project.
Principal Products
The company’s principal product is gold dore. The company’s revenue is primarily generated from the sale of gold dore to refiners with precious metals expertise.
Material Mineral Properties
The company’s material mineral projects are the Segovia Operations, Marmato Mine, Soto Norte Project and Toroparu Project.
Segovia Operations
The Segovia Operations (Segovia) are located in the Segovia-Remedios mining district in the department of Antioquia, Colombia, approximately 180 km northeast of Medellín, at 7°04’ North and 74°42’ West. Segovia is readily accessible by vehicle on national highways and sealed secondary roads leading 195 km to the northeast from Medellín.
Segovia is a historical and current mining operation comprising four active underground gold mining operations, which include El Silencio, Sandra K, Providencia, and Carla, together with other mineral resources and exploration targets, a processing facility that processes both ore produced from the Property’s mineral reserves and material that is mined by smaller groups outside of the Property titles, tailings management facilities, and numerous historical mines.
In addition to the mining titles that provide legal access to the Property, Aris Mining owns land with a total area of 4,727.2 ha and leases a further 2.4 ha of land to support the mining activities at Segovia.
The Segovia Operations' geology is dominated by the Segovia Batholith, andesite to dolerite dikes, an extensive system of high grade gold mineralized quartz veins, and faulting resulting in offsets of the veins. The veins are controlled mainly by northeast trending, shallowly dipping faults associated with diorite to andesite dikes.
Marmato Mine
The Marmato underground gold mine (Marmato, the Property, or the Project) is located on the west side of the town of Marmato, in Marmato municipality of Caldas Department, in the Republic of Colombia, approximately 80 kilometres (km) from Medellín and 200 km northwest of the capital city of Bogotá.
Cerro El Burro, a prominent hill at Marmato, has been mined for nearly 600 years, and was historically divided into three contiguous mining titles with numerous licenses within them, including Zona Alta (#CHG_081), Zona Baja (#014-89m), and Echandia (#RPP-357). The Maruja Mine in the Zona Baja title was first developed between 1908 and 1925 by the Colombian Mining and Exploitation Company, which mined extensively in the upper levels from the haulage level on Level 18 at 1,160 metres (m) above sea level, and opened the Zancudo mine adit on Level 17, 50 m above Level 18. In 1925, the mines were expropriated and closed. In 1993 Mineros Nacionales S.A.S. began a 300 tpd underground mine on Level 18. Mining has taken place continuously since then by a series of different owners in the area known as the Upper Mine in the Zona Baja mining title. In 2012, GCM Mining Corp. (GCM Mining), a publicly listed Canadian company formerly known as Gran Colombia Gold Corp. (Gran Colombia Gold), and currently known as Aris Mining, announced the discovery of a deep mineralization trend, referred to as the Lower Mine, 300 metres below the then known resources in the Upper Mine.
Aris Gold Corporation (Aris Gold) owned 100% of the Zona Baja (014-89m) mining title, 2.7778% of GCM Mining’s Zona Alta (CHG_081) mining title, and held rights to mine in GCM Mining’s Echandia (RPP-357) mining title.
The Marmato gold deposit is located on the eastern side of the Western Cordillera of the Colombian Andes and is hosted in the Marmato Porphyry Suite. At the Property, the andesitic to dacitic Marmato Porphyry Suite intrusions are characterized by quartz, hornblende, biotite, and zoned plagioclase phenocrysts in a finely crystalline quartz-plagioclase groundmass.
Soto Norte Project
Soto Norte is an advanced exploration stage underground gold project located in the department of Santander, Colombia. Mubadala Investment Company (MIC) is the 100% owner of the Minesa Group, consisting of AUX Colombia S.A.S. (AUX), known as Sociedad Minera de Santander (Minesa), Sociedad Minera Calvista Colombia S.A.S. (Calvista) and Galway Resources Holdco Ltd. Sucursal Colombia (Galway). Minesa is the 100% owner of the Soto Norte Project.
The Soto Norte Project is developed in Concession 095-68 and has a works and construction program (PTO) approved by the National Mining Agency (ANM) as a program of mine development and production, Act number 000195 of October 13, 2017. The Soto Norte mineral resources and reserves at the Soto Norte Project are located entirely within Concession 095-68.
Soto Norte is an advanced exploration stage underground gold project located in the Soto Norte Province of the department of Santander, Colombia. The Minesa Group, consisting of AUX Colombia S.A.S. (AUX), currently known as Sociedad Minera de Santander (Minesa), Sociedad Minera Calvista Colombia S.A.S. (Calvista), and Galway Resources Holdco Ltd. Sucursal Colombia (Galway) holds the various mining tenements forming the Soto Norte Project. In April 12, 2022, Mubadala Investment Company (Mubadala) and Aris Gold Corporation formed the Soto Norte joint venture where Mubadala retained an 80% ownership interest and Aris became the project operator and acquired a 20% ownership interest and an option to increase to 50% ownership.
The Soto Norte mineral deposit is classified as a high-sulphidation epithermal deposit, with gold, silver and copper occurrences, mainly in sulphides.
Toroparu Project
The Toroparu Project is located in the Cuyuni-Mazaruni Region of Guyana, approximately 215 kilometres southwest of the capital city of Georgetown. The Toroparu Project and adjacent properties are collectively known as the Upper Puruni Concessions. The Toroparu Project contains two gold deposits with mineral resources, referred to as Toroparu deposit and Sona Hill deposit (collectively Toroparu unless otherwise indicated). The Sona Hill deposit is located approximately 5 km to the southeast of the Toroparu deposit.
The Toroparu Project is 100% owned by Aris Mining through its indirectly owned subsidiary, ETK, Inc. (ETK).
The Toroparu and Sona Hill deposits are located in the Amazonian Craton of the Guiana Shield, within the northwest trending Puruni volcano-sedimentary belt, in a sequence of meta-sedimentary and meta-volcanic rocks along the contact of a small intra- belt pluton.
Environmental Protection
The company holds a formally accepted amended Environmental Management Plan (PMA) for the El Silencio, Providencia, and Sandra K mines at the Segovia Operations which was approved on February 22, 2019, with a renewal period of five years, as well as an approval granted on November 25, 2019, both of which jointly approve the PMA for the Segovia Operations, with an expiry in December 2024.
Mining at Marmato predates the regulatory requirements to prepare an environmental impact assessment as part of the permitting process. The Upper Mine operations are authorized through the approval of the PMA on October 29, 2001, covering environmental studies and management procedures for the Upper Mine. The construction of the Lower Mine expansion Project is authorized through the approval of the Lower Mine PMA on July 12, 2023.
History
The company was formerly known as GCM Mining Corp. and changed its name to Aris Mining Corporation in September 2022.
