Vancouver, Canada, March 6, 2024 – Aris Mining Corpora�on (Aris Mining or the Company) (TSX: ARIS; NYSE -A:

ARMN) announces financial and opera�ng results for the three and twelve months ended December 31, 2023 (Q4

2023 and FY 2023, respec�vely). All amounts are in US dollars unless otherwise indicated.

Gold Produc�on 61,052 ounces 226,151 ounces

Segovia Opera�ons AISC/oz1 $1,264 $1,173

EBITDA1 $19.7M $112.1M

Adjusted EBITDA1 $39.7M $159.4M

Adjusted earnings1 $11.8M or $0.09/share $52.2M or $0.38/share

Aris Mining CEO Neil Woodyer stated: “In 2023, we restructured the opera�ons team and introduced new opera�ng

procedures following the combina�on of GCM Mining and Aris Gold in September 2022 . The new team achieved

consistent quarter-over-quarter increases in gold pro duc�on during 2023, significantly enhancing our posi�on in

2024 and the future. We have achieved the ini�al phase of our vision to create an atrac�ve gold mining company

for investors by integra�ng profitable opera�ons with explora�on poten�al and growth projects.

During 2023, our high-grade Segovia Opera�ons produced 202,940 ounces of gold at a processed grade of 10.4 g/t

with all-in sustaining costs per ounce of $1,173, achieving produc�on and AISC guidance. For the full year 2023, our

mines generated $75.4 million in free cash flow from opera�ons1 which largely funded $84.2 million in growth and

expansion investments, and we ended the year with a cash posi�on of $195 million.

With strong gold produc�on results and substan�al growth in mineral reserve s and resource s at our Segovia

Opera�ons, we have started construc�on to increase its processing capacity by 50% to 3,000 t onnes per day with

comple�on expected in early 2025 . As the new capacity is used, we expect to increase annual gold produc�on at

Segovia to over 300,000 ounces. Construc�on at our Marmato Lower Mine project has ramped up with ini�al access

roads completed, the lead contractor for portal and decline development selected, and tenders for key items for the

new processing plant underway. We are on pace to reach 500,000 ounces of gold produc�on in Colombia in 2026.”
