ARIS MINING ANNOUNCES UPDATED MINERAL RESOURCE
ESTIMATE FOR THE TOROPARU PROJECT IN GUYANA
Vancouver, Canada, March 14, 2023 – Aris Mining Corporation ( “Aris Mining” or the “Company” ) (TSX:
ARIS; OTCQX: TPRFF) announces an updated mineral resource estimate for the Toroparu Project in Guyana,
effective February 10, 2023 (the “2023 MRE”). Aris Mining will file an updated technical report in support
of the 2023 MRE within 45 days of this news release.
Neil Woodyer, CEO of Aris Mining, commented : “Following completion of the GCM Mi ning and Aris Gold
merger in September 2022 , Aris Mining started a re-evaluation process for the Toroparu Project and
reduced the previously planned expenditures until the development plan is fully defined . Today, we are
reporting the results of the updated mineral resource estimate which is based on a new detailed structural
analysis and updated geological model. The Aris Mining team has confirmed that Toroparu is a large-scale
gold-copper deposit with an updated measured and indicated resource estimate of 5.4 million ounces of
gold and 118 thousand tonnes of copper , and an inferred resource estimate of 1.2 million ounces of gold .
We are progressing additional studies to update, fully define, and optimize the development plan.”
