Work in progress

Planned works

As part of the Marban Alliance project’s development, a number of field projects are being carried out.

Exploration work is aimed at gaining a better understanding of the geological characteristics of the deposit and obtaining the information required for techno-economic studies.

Geotechnical and hydrological work is also required for the techno-economic studies, which assess the project’s technical and economic feasibility.

As part of the environmental assessments, we also need to collect data on fauna, flora, water, air and so on.

In order to better inform the neighborhood about our activities, a schedule and a map showing the location of the various works are available.

This information will be updated regularly.

Find below the calendar and maps of work planned for spring 2024.

Responsible Exploration Program

O3 Mining Responsible Exploration Program: the application of best practices in mining exploration.

Stemming from O3 Mining sustainable development policy and its ECOLOGO® certification, the company’s Responsible Exploration Program aims to showcase its practices in community relations, environmental protection and economic development. This program groups together the responsible practices applied during exploration work on all O3 Mining properties. The following eight principles guide this program and dictate our actions:

  1. Reduce our impact;
  2. Safeguard the health and safety of workers and local population;
  3. Integrate leading practices in governance;
  4. Apply ethical business practices;
  5. Respect our stakeholders;
  6. Continuously assess the risks of each project and act with due diligence;
  7. Engage host communities and other affected and interested parties;
  8. Create long-term value for our stakeholders.

Every new employee, contractor or person accessing O3 Mining’s properties must attend a one-hour induction training session. The session is divided into three parts: introduction to the company, health and safety, and sustainability. One of the topics covered in the induction training is the code of conduct that must be followed by anyone working at O3 Mining sites.

In addition to induction training, Minière O3 offers training to employees in environment and health/safety.

Agrement guide for surface owners

To prospect for minerals, a company must hold the right to explore a well-defined area known as a claim. This right gives the claim holder exclusive rights to carry out exploration work. However, the company must have permission from the surface owner to access the claims. In order to carry out work on land it does not own, O3 Mining requires prior written authorization from the lot owner.

Any lot owner has the right to refuse access to his or her property, thereby refusing to sign an access agreement. We will never enter your property without your permission.
