Val-d'Or - O3 Mining Inc. (TSXV: OIII; OTCQX: OIIIF) ('O3 Mining' or the 'Corporation') is working to implement a participatory approach in conjunction with citizens and other stakeholders pertinent to its Marban project.

To achieve this, the company is meeting the citizens located in the project's proximity. The objective is to obtain feedback from the residents of the sector and determine the most suitable and effective mechanism to exchange through the continuation of discussions.

Vice-President, Sustainable Development and Human Resources, Myrzah Bello, explains, 'When we met with citizens last September, we committed to keeping them informed on the progression of the project. We are and will always be attentive to the concerns and questions of our host community. I sincerely believe that together we can build an innovative and beneficial approach for all stakeholders involved'.

As part of these meetings, the Company also consulted citizens on the deviation of Chemin Gervais, which will be necessary if the project materializes.

O3 Mining is also aiming to define collaboratively a fair and transparent framework with the residents and businesses that will be affected by the acquisition of their property if the project materializes and those who will live nearby the mine. It is essential for O3 Mining to jointly establish an acquisition protocol with the residents, all while taking their concerns into account.

The Company, which is at the pre-feasibility stage, is currently working on the technical and economic viability of the Marban project. Several steps remain to be crossed, but O3 Mining is confident in the project's viability.
