Toronto, May 13, 2020 – O3 Mining Inc. (TSX.V:OIII) (“O3 Mining” or the “Corporation”) is pleased to announce it will resume exploration activities on it’s Val D’Or properties following an announcement from the Government of Quebec, which eases restrictions previously in place due to COVID-19.

Consistent with past practice, the Company’s priority in this resumption will be the health and safety of its employees and contractors, their families, and communities in which we operate.  The company is applying the recommendations that the National Institute of Public Health of Quebec (INSPQ) and the CNESST have published for preventive measures as well as a guide to sanitary standards for the mining sector. Personnel will be subject to heightened health and safety standards in accordance with precautions put in place by the Government of Quebec and the Corporation. Teleworking will continue for all staff and management not required at site. The Val D’Or office has the full suite of safety protocols in place, including active monitoring to ensure that all the work is performed respecting physical distancing protocols and the use of personal protective equipment. Additionally, the facilities have been thoroughly disinfected, with additional hygiene and sanitation stations and controls in place. Two drill rigs will be mobilized after spring break up in June to continue the planned 50,000 metres drilling program. One drill rig will be on the Alpha property focused on Bulldog and Orenada Zone 4 and the second will be on the East Cadillac property targeting the North Contact zone.

O3 Mining President and CEO Jose Vizquerra commented: “The health and safety of our employees and contractors, their families, and the entire Val D’Or community is our main priority. We have been diligent in temporarily closing, deep cleaning and establishing health and safety measures to ensure the safe and easy transition of our personnel back to the workplace. With the safety protocols in place, we are confident that we can adapt our business and continue to provide a safe and healthy workplace and create long-term value for our shareholders as we resume our drilling program”
