Current Program

In addition to our ongoing Substantially Started activities, Seabridge’s current programs are focusing on completing data collection to advance the project into final feasibility.  Tasks being undertaken for this effort include: geotechnical drilling for infrastructure installation; waste rock categorization; surface and sub-surface water characterization; road and power sighting; construction and operation scheduling; and reclamation designs.  The exploration team is focused on optimizing the resource models and designing programs for detailed definition drilling of deposits prior to making a production decision. Further exploration drilling has been suspended in recognition of the fact that resources and reserves are more than adequate for a multi-generational mine.
