ARIS MINING REPORTS Q1 2024 RESULTS WITH SEGOVIA GENERATING $13.8 MILLION IN OPERATING CASH FLOW

Aris Mining Corp. has released its full financial and operating results for the three months ended March 31, 2024 (Q1 2024). Aris Mining previously released Q1 2024 production results and announced that it is on track to deliver full-year 2024 guidance while its expansion projects advance in a news release dated April 15, 2024. All amounts are in U.S. dollars unless otherwise indicated.

Aris Mining chief executive officer Neil Woodyer stated: "During Q1, our high-grade Segovia operations produced 44,909 ounces of gold at a processed grade of 9.42 g/t, which was in line with our mine plan for the quarter. As we announced in April, our operations are on track to achieve full-year 2024 production guidance of 220,000 to 240,000 ounces. AISC per ounce at Segovia of $1,434 were also in line with budgeted expectations. During Q1, the Segovia operations generated $13.8-million in cash flow from operations before expansion capital and taxes. We invested $37.4-million in our projects and mines, and we ended the quarter with a cash position of $147-million.

"Both of our expansion projects progressed well during the quarter. At Segovia, the mill expansion from 2,000 to 3,000 tonnes per day has advanced with completion of mill sizing optimization studies, civil works for the relocated CMP mill feed receiving area are 85 per cent complete, major equipment orders have been placed, and geotechnical testwork for the mill and silo foundations are complete.

"At the Marmato lower mine, most of the mechanical equipment has been ordered, including the crushers, ball and SAG mills, gravity concentrators, thickeners, and filter presses. The access road has reached the portal level, which allows the portal contractor access to their work area, and the second phase of the contract for the decline development has been submitted to a third party review and will be awarded soon."

Aris Mining's condensed consolidated interim financial statements for the three months ended March 31, 2024, and March 31, 2023, and the related MD&A (management's discussion and analysis) (together, the quarterly filings) are available on SEDAR+, in the company's filings with the U.S. Securities and Exchange Commission (SEC), and in the financials section of Aris Mining's website.

About Aris Mining Corp.

The Segovia operations and Marmato upper mine produced 226,000 ounces of gold in 2023. Aris Mining is targeting a production rate of 500,000 ounces of gold per year in the second half of 2026, following a ramp-up period after the Segovia mill expansion scheduled for completion in Q1 2025 and the Marmato lower mine's first gold pour in late 2025. Aris Mining also operates the Proyecto 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 Toroparu, a gold/copper project. Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification.

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

Non-IFRS (international financial reporting standards) measures

Free cash flow, cash costs, AISC (all-in sustaining cost), EBITDA (earnings before interest, taxes, depreciation and amortization), adjusted EBITDA, adjusted (loss)/earning, sustaining capital and expenditures on growth capital are non-IFRS financial measures and non-IFRS ratios. These measures do not have any standardized meaning prescribed under IFRS and therefore may not be comparable with other issuers.

Attached tables reconcile the non-IFRS 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 Q1 2024 interim financial statements.
