VANCOUVER, British Columbia, Feb. 16, 2021 (GLOBE NEWSWIRE) -- Atico Mining Corporation (the Company or Atico) (TSX.V: ATY | OTC: ATCMF) reports a temporary work stoppage at the El Roble mine to install a new relief valve for the pipeline that transports material to the tailings facility and to perform a final systems inspection.

The safety of people and the environment remains a priority for Atico at the El Roble mine. On February 11, 2021, the relief valve for the tailings pipe malfunctioned and as a result some material was discharged. The Company has taken immediate corrective action and is working with the provincial authority to verify that there are no further actions needed.

On February 11th, operations immediately halted while repairs were made and a complete inspection of the system was performed.

At this point in time, the Company does not believe the incident posed any material threat to the health of employees, communities, or the environment. After an inspection by the provincial authorities, the Company plans to gradually resume operations in the next 24 hours.
