ARIS MINING TO L IST COMMON SHARES ON NYSE AMERICAN ,

DRIVEN BY OUR GROWTH AND PROJECT ADVANCE MENT S

Vancouver, Canada, September 6, 2023 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS;

OTCQX: TPRFF) announces that it has received approval to list its common shares on the NYSE American

LLC (NYSE American). Since the launch of Aris Gold two years ago , Aris Mining has grown to include two

operating mines producing over 230,000 ounces of gold per year and generated US$153 million of Adjusted

following receipt of permits in July 2023. Aris Mining is also advancing the Soto Norte gold/copper project,

which is positioned to become one of Colombia’s largest and most advanced underground mines.

Neil Woodyer, CEO of Aris Mining, commented “Listing Aris Mining on the NYSE American will increase our

visibility to investors in the United States and internationally. We are optimizing our operations with a focus

on cash flow generation, extending mine life, building new mines, and exploring acquisitions. Aris Mining

has a strong balance sheet and we believe we are on track to produce 400,000 ounces of gold in Colombia

in 2026, based on steady-state production from our Segovia Operations and the expanded Marmato Mine.

As we step forward, our strategy is centered around the belief that success ful mining in Colombia hinges

on our collaboration with and support of local Artisanal and Small-Scale Miners.”

Thursday, September 14, 2023 under the symbol “ARMN”, with trading on the OTCQX to cease concurrent

with the NYSE American listing. The Company will remain listed on the Toronto Stock Exchange under the
