New Gold Inc. confirmed the structural integrity of the New Afton tailings storage facility and announces resumption of all underground mining activities at its New Afton Mine, located in Kamloops B.C. During regular inspections of the New Afton Tailings Storage Facility completed on August 9, 2023 visual geotechnical variances were observed that required further review by the Engineer of Record. The Company acted promptly, advising the relevant authorities, and proactively suspending underground mining activities with health, safety and the wellbeing of employees, contractors, and communities as top priority. The EOR completed a thorough review on August 10, 2023 and confirmed that the NATSF structural integrity and behavior is normal and expected.

On the evening of August 10, 2023 the Company resumed normal underground mining activities on site. Milling operations were unaffected during this period and in-pit tailings deposition continued as planned. New Afton remains well positioned to meet all annual production and cost guidance metrics as set out earlier in the year.

C-Zone remains well positioned for first production ore in the fourth quarter, with commercial production planned for the second half of 2024.
