ARIS MINING ANNOUNCES RECEIPT OF LICENSE TO TRANSFORM MARMATO MINE AND NEW PATH FORWARD FOR GOLD PROJECTS IN COLOMBIA

VANCOUVER, BC, July 12, 2023 /PRNewswire/ - Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS) (OTCQX: TPRFF) announces it has received approval from the Corporación Autónoma Regional del Caldas (Corpocaldas), a regional environmental authority in Colombia, of the Environmental Management Plan (PMA) which now permits the development of the Marmato Lower Mine.

Construction of the new underground mine will provide access to the wider porphyry mineralization below the current Upper Mine, which allows for bulk mining methods in the Lower Mine. The Upper and Lower Mine has a measured and indicated mineral resource of 6.0 million ounces (Moz) of gold, which includes a proven and probable mineral reserve of 3.2 Moz. The Marmato Mine is expected to deliver average production of 162,000 ounces per year over a nearly 20-year mine life from the mineral reserves.¹

Aris Mining CEO Neil Woodyer stated: "This is a milestone for Aris Mining as it will grow Marmato's gold production five-fold and, following construction, our Colombian gold production from Segovia and Marmato will be approximately 400,000 oz per year.

This $280 million project is fully funded from our current cash balances and the $122 million of stream funding from Wheaton Precious Metals. Additionally, our Segovia Operations generate significant positive cashflow.  The project is scheduled to pour its first gold by the end of Q3 2025. 

We thank our artisanal and small mine partners and our communities for their substantial support and efforts during the Marmato Lower Mine project licensing process. The town of Marmato has been the centre for gold mining since it was founded in 1540 with artisanal and small scale miners being at the heart of the community.

This permitting of a new, underground gold mine is a significant achievement for Aris Mining, the Marmato community and the Colombian gold mining industry. We believe this successful partnering process establishes a new path forward for gold mining in Colombia."

In November 2022, Aris Mining announced the results of the Marmato Lower Mine expansion Preliminary Feasibility Study (PFS), and increased proven and probable gold mineral reserves by 57% to 3.2 Moz¹. The Lower Mine project includes the development of a new underground mine and a 4,000 tonne per day (tpd) ore processing facility to add to the currently operating Marmato Upper Mine.

• The total project cost estimate remains at $280 million, including $17 million spent since the PFS on pre-construction activities related to mine development, camp access and road design, EPCM services, and land acquisition.
• All the land required for construction has been secured.
• Tender bids for key long lead procurement items such as mills, crushers, feeders, thickeners, oxygen plant, gold room, and filters are currently in the market with orders to be placed in Q3 2023.
• Construction of the access road to the new process plant and mine portal and declines will commence in Q4 2023, followed by the start of construction of the process plant, mine and non-process infrastructure.
• The new 4,000 tpd mill is on schedule for mechanical completion in Q3 2025.
• Ausenco has been appointed EPCM contractor for the process plant.
• In addition to the site infrastructure, a 32-kilometre 115 kV transmission line will be built on a 'buy build operate' basis to provide power to the Lower Mine, related processing facilities and infrastructure.

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 235,000 ounces of gold in 2022. 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. Aris Mining plans to pursue acquisition and other growth opportunities to unlock value creation from scale and diversification.

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