GCM MINING AND ARIS GOLD COMPLETE BUSINESS COMBINATION TO CREATE ARIS MINING

VANCOUVER, BC, Sept. 26, 2022 /CNW/ - GCM Mining Corp. (GCM Mining) (TSX: GCM) (OTCQX: TPRFF) and Aris Gold Corporation (Aris Gold) (TSX: ARIS) (OTCQX: ALLXF) have completed the business combination previously announced on July 25, 2022. The combined entity has been renamed Aris Mining Corporation and operates several high-grade underground mines at its Segovia Operations and the Marmato Mine, which together produced 230,000 ounces of gold in 2021. Aris Mining also owns two advanced development projects, the Marmato Lower Mine expansion and Toroparu Project, and is the operator and 20% shareholder of the Soto Norte joint venture, a large-scale underground project advancing its environmental permitting.

Neil Woodyer, CEO of Aris Mining, stated: "Over the past 18 months, our team has completed three transactions that have resulted in the creation of Aris Mining. We have an attractive mix of production, cash flow and near-term growth projects, all of which are supported by sizable mineral reserves or resources and strong financial, technical, and operating teams.  Within Colombia, we are integrating the teams at Segovia and Marmato. The Segovia Operations incorporates an industry-leading artisanal small miner program that has enhanced relations with the local community and improved the environment by eliminating the use of mercury and the discharge of tailings into waterways, and we look forward to expanding these opportunities for both the Marmato and Soto Norte communities. We will continue to strengthen stakeholder engagement to deliver mining projects which promote local development and are aligned to best environmental practices."

The Board of Directors and leadership team of Aris Mining are as follows:

Aris Mining expects to welcome Mónica de Greiff as a member of the Board of Directors in early October 2022.

Aris Mining has approximately $352 million of cash, free cash flow generation from the Segovia Operations, and approximately $260 million of additional committed funding from precious metals stream agreements available to fund growth projects¹. Aris Mining has proven and probable mineral reserves of 3.8 million ounces of gold, measured and indicated mineral resources of 18.3 million ounces of gold, inclusive of mineral reserves, and inferred mineral resources of 7.7 million ounces of gold.  See Tables 1, 2, and 3 in the Appendix for details. 

A new corporate website has been launched at www.aris-mining.com which contains information on Aris Mining's mines and projects, along with information about the Board of Directors, management team and approach to corporate governance and sustainability.

At closing, GCM Mining was renamed Aris Mining Corporation and Aris Gold amalgamated with 1373945 B.C. Ltd. to form Aris Mining Holdings Corp. (Aris Holdings), which is now a wholly owned subsidiary of Aris Mining.

Aris Mining now has approximately 136.1 million issued and outstanding common shares, inclusive of the new common shares issued to acquire Aris Gold.

Table 1: Aris Mining proven and probable mineral reserves

Table 2: Aris Mining measured and indicated mineral resources

Table 3: Aris Mining inferred mineral resources

Measured and Indicated mineral resources are reported inclusive of mineral reserves. Mineral resources and reserves are as defined by the Canadian Institute of Mining, Metallurgy, and Petroleum's 2014 Definition Standards for Mineral Resources & Mineral Reserves. Mineral resources are not mineral reserves and have no demonstrated economic viability. There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.

The mineral resource and reserve estimates were prepared following the Canadian Institute of Mining, Metallurgy, and Petroleum's Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines. Each of the Qualified Persons responsible for the preparation of the mineral resources have reviewed and verified the drilling, sampling, assaying, and QAQC protocols and results, and are of the opinion that the sample recovery, preparation, analyses, and security protocols are reliable for the mineral resource and reserve estimates.
