Winter activities: January to April

Definition drilling campaign on the Malartic H Zone:

We will carry out definition drilling on the Malartic H zone to confirm the resource announced in the June 20, 2023 press release.   The objective of the definition drilling campaign will be to provide a better definition of the potential deposit. Three drill rigs will be in the identified area from January 4 to April. The map shows the location of the drilling zone, as well as the roads that will be prepared to allow the drills and machinery to move around the identified area.

The map below shows the areas where works will be carried out starting in January, in the Malartic H zone.

We will carry out geotechnical drilling to determine soil composition and install observation wells to study underground water.

  • 27 geotechnical drillings, 3 drilling rigs to carry out 25 soil drillings and 2 drillings to characterize groundwater;
  • 1 geomechanical drill and 1 geological drill;
  • Ongoing air quality monitoring.
