VANCOUVER, BC, May 7, 2025 /PRNewswire/ - Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS) (NYSE-A: ARMN) announces its financial and operating results for the three months ended March 31, 2025 (Q1 2025), with a strong start to the year marked by record gold prices, solid production performance, and continued investments in growth. Adjusted earnings per share (EPS) of $0.16 is the highest full quarter result since Aris Mining was formed in September 2022.  All amounts are expressed in U.S. dollars unless otherwise indicated.

Neil Woodyer, CEO, commented "Aris Mining had a strong start to 2025, driven by solid operational execution, higher gold prices, and continued progress on our growth initiatives. At Segovia, we maintained production and high margins while advancing the plant expansion, which remains on track for commissioning in June. At Marmato, we are making steady progress on the Lower Mine development, with construction spend ramping up and plant capacity now targeting 5,000 tonnes per day. At our Toroparu Project in Guyana, we have launched a new study to update the development plan, and we look forward to demonstrating the potential of this project."

Completion of the PEA is expected in Q3 2025.

Capital Structure Update

As of May 6, 2025, Aris Mining has approximately 178.1 million common shares issued and outstanding, with 48.0 million ARIS.WT.A warrants remaining outstanding, which if fully exercised would result in the issuance of 24.0 million new Aris Mining shares and additional proceeds to the Company of C$132 million (or $96 million).

Following the expiry of the ARIS.WT.A warrants on July 29, 2025, the Company will have no remaining convertible securities outstanding, other than stock options issued under its stock option plan.

Since issuing its new $450 million senior unsecured bonds in October 2024, Aris Mining has steadily reduced both its total and net leverage ratios. As of March 31,2025, total leverage was 2.4x³ and net leverage was 1.2x³.

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a leading Latin 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 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 Upper Mine, 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 following the ramp-up of the Segovia mill expansion, expected during the second half of 2025, and the new Marmato Mine, which is expected to start ramping up in H2 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 by mid-2025. In Guyana, Aris Mining owns the Toroparu gold/copper project, where a new Preliminary Economic Assessment (PEA) has been commissioned.

Colombia is rich in high-grade gold deposits and Aris Mining is actively pursuing partnerships with the Country's dynamic small-scale mining sector. With these partnerships, we enable safe, legal, and environmentally responsible operations that benefit both local communities and the industry.

Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification.

Non-GAAP Measures

EBITDA, adjusted EBITDA, adjusted (net) earnings, cash cost, total leverage, net leverage and AISC are non-GAAP financial measures and non-GAAP ratios. These financial measures do not have any standardized meaning prescribed under IFRS or by Generally Accepted Accounting Principles (GAAP) in the United States, and therefore may not be comparable to other issuers. For full details on these measures and ratios refer to the "Non-GAAP Financial Measures" sections of the Company's Management's Discussion and Analysis for the three months ended March 31, 2025 and 2024 and years ended December 31, 2024 and 2023 (MD&As). The MD&As are incorporated by reference into this news release and are available at www.aris-mining.com, on the Company's profile on SEDAR+ at www.sedarplus.ca and in its filings with the SEC at www.sec.gov.

We have presented total leverage and net leverage as non-GAAP ratios in this press release. Total leverage is calculated as  the outstanding principal of the Company's debt instruments divided by trailing twelve-month adjusted EBITDA, and net leverage is calculated as net debt divided by trailing twelve-month adjusted EBITDA. We believe these ratios provide useful information to analysts, investors, and other stakeholders in assessing the Company's leverage and evaluating our balance sheet.

The tables below reconcile the non-GAAP financial measures contained in this news release for the current and comparative periods to the most directly comparable financial measure disclosed in the Company's interim financial statements for the three months ended March 31, 2025 and 2024, and Company's annual financial statements for the three months and years ended December 31, 2024 and 2023.
