VANCOUVER, BC, Nov. 14, 2022 /PRNewswire/ - Aris Mining Corporation ("Aris Mining" or the "Company"), formerly GCM Mining Corporation ("GCM Mining") (TSX: ARIS) (OTCQX: TPRFF) announces financial and operating results for the three and nine months ended September 30, 2022 ("Q3 2022 and YTD 2022"). All amounts are in US dollars unless otherwise indicated.

Q3 2022 Highlights:

• Cash and cash equivalents of $326 million and access to $260 million of future project construction funding, as of September 30, 2022
• Gold sales of 53,411 ounces in Q3 2022 at AISC¹ per ounce sold of $1,115, with gold sales up 6% over the same quarter last year
• Income from mining operations of $39.8 million for Q3 2022 and $122.2 million for YTD 2022

Aris Mining CEO Neil Woodyer stated: "We are pleased to report on the integrated group results following the combination of GCM Mining and Aris Gold on September 26. We have reorganized our Colombian operations around GCM Mining's Medellin office, transferred the corporate office from Toronto to Vancouver, established a new system of governance and leadership for our community social programs, started implementing new reporting systems focused on cost controls, and re-branded our operations and offices as Aris Mining.

"During Q3 2022, the expansion of the Segovia Operation's Maria Dama processing facility to 2,000 tpd from 1,500 tpd was completed, resulting in gold production of 54,630 ounces during the quarter. The Segovia Operations generated $57 million of after-tax cash flow during the first nine months of 2022, with the historic Marmato Upper Mine contributing another $2 million while the site prepares for the Marmato Lower Mine expansion project.

"Earlier today we announced the completion of updated mineral resource and reserves estimates and the results of the Preliminary Feasibility Study for the Marmato expansion project, effective June 30, 2022, which is expected to be filed in November 2022. The updated Marmato Lower Mine construction capital estimate of $280 million will be partially funded from $122 million of committed stream financing, for a net construction funding amount of $158 million. Since March 2020 we have increased measured and indicated mineral resources by 47% to 6.0 million ounces of gold, mineral reserves by 57% to 3.2 million ounces, and, at the base case $1,600 gold price, the project NPV_5% is $341 million and the IRR is 30%.² Following construction of the new Lower Mine, the Marmato operation is expected to deliver average production of 162,000 ounces per year over a nearly 20-year mine life.

"We are also pleased to announce approval of the Marmato Plan de Trabajos y Obras or PTO, a long-term technical operations concept, by the Agencia Nacional de Minería, as a progressive step toward fully permitting the expansion project. We continue to advance the process to amend the Marmato environmental license with the Autoridad Nacional de Licencias Ambientales. 

"We are now focused on a re-evaluation of the Toroparu Project in Guyana, including a review to validate the previous management team's plan to construct the processing plant in two phases. During this period and until the development plan is fully defined, we are reducing previously planned expenditures."

Aris Mining is a Canadian company led by an executive team with a track record of creating value through building globally relevant mining companies. In Colombia, Aris Mining 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 operates the Soto Norte joint venture, where environmental licensing is advancing to develop a new underground gold, silver and copper mine. In Guyana, Aris Mining is advancing the Toroparu Project, a gold/copper project with expected average gold production of 225,000 per year over the life of mine. Aris Mining plans to pursue acquisition and other growth opportunities to unlock value creation from scale and diversification.

Aris Mining promotes the formalization of small-scale mining as this process enables all miners to operate in a legal, safe and responsible manner that protects them and the environment.

Non-IFRS Measures

Cash costs ($ per oz sold), AISC ($ per oz sold), EBITDA, adjusted EBITDA, adjusted (loss)/earnings and additions to mining interests are non-IFRS financial measures and non-IFRS ratios in this document. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers. For full details on these measures and ratios refer to the Non-IFRS Measures section of the Company's Management's Discussion and Analysis for the three and nine months ended September 30, 2022, which is incorporated by reference into this news release and is available on SEDAR at www.sedar.com.

Aris Mining changed the method of calculating cash costs in Q3 2022 and all historical information was adjusted. Total cash costs now exclude royalties and include the appropriate mine-level general and administrative costs. General and administrative costs associated with the corporate office (Canada) and the arbitration proceedings with the International Centre for Settlement of Investment Disputes in respect of its claim against the Republic of Colombia are excluded from the calculation. Management considers that royalties are not controllable by the operations team and as such exclude them from their controllable costs – these costs are included in AISC below. Conversely, mine-level general and administrative costs are controllable by the operations team and as such are included in total cash costs.

Aris Mining changed the method of calculating AISC in Q3 2022 and all historical information was adjusted. AISC now excludes all non-mine-level general and administrative costs, environmental penalties and non-mine-level lease payments. Management considers that these costs are not controllable by the operations teams.

The Toroparu Preliminary Economic Assessment is preliminary in nature and is based on numerous assumptions and includes inferred mineral resources. The inferred mineral resources are considered too speculative geologically to have 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. Scientific and technical information concerning Toroparu is summarized, derived, or extracted from the Toroparu Technical Report entitled "Revised NI 43-101 Technical Report and Preliminary Economic Assessment for the Toroparu Gold Project, Upper Puruni River Region of Western Guyana" dated February 4, 2022 with an effective date of December 1, 2021.

Geo., Brian Wissent, P.Eng, Daniel Yang, P.Eng, Ben Peacock, P.Eng, Kurt Boyko, P.Eng, Fernando Rodrigues, MMSAQP, and David Willms, P.Eng, each of whom is independent of GCM within the meaning of NI 43-101 and is a "Qualified Person" as such term is defined in NI 43-101.
