Cash costs ($ per oz sold) and AISC ($ per oz sold) are non-IFRS financial measures and non-IFRS ratios in this press release. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers. Please refer to the Non-IFRS Measures section of the Company's most recently filed Management's Discussion and Analysis which is available on SEDAR at www.sedar.com for full details on these measures, which is incorporated by reference into this press release.

Aris Mining changed the method of calculating cash costs in the third quarter of 2022 and all historical information was adjusted. Total cash costs now exclude royalties and include the appropriate mine-level general and administrative costs. General and administrative costs associated with the corporate office (Canada) and the arbitration proceedings with the International Centre for Settlement of Investment Disputes in respect of its claim against the Republic of Colombia are excluded from the calculation. Management considers that royalties are not controllable by the operations team and as such exclude them from their controllable costs – these costs are included in AISC above. Conversely, mine-level general and administrative costs are controllable by the operations team and as such are included in total cash costs.

Aris Mining changed the method of calculating AISC in the third quarter 2022 and all historical information was adjusted. AISC now excludes all non-mine-level general and administrative costs, environmental penalties and non-mine-level lease payments. Management considers that these costs are not controllable by the operations teams.
