SnapshotThe Santa Luz C1 Underground resources are a proximal down-dip extension of the Mineral Resource exploited by the C1 open pit.

The Santa Luz C1 Underground project could be operated concurrently with the existing open pit mine. If Equinox Gold elects to develop the C1 Underground, development of the main decline would take approximately two years.

Summary:

Host rocks to the underground Mineral Resource include carbonaceous metasedimentary rocks, dioritic and dacitic intrusive rocks, and metavolcanic rocks. The majority portion of the underground resource is classified as carbonaceous breccia. The mineralization style is quartz-carbonate-sulfide veins and breccia fillings hosted in a major, district-scale shear zone, typical of orogenic gold deposits.

The shear zone is north to northeast trending and dips moderately to the west. In the underground resource area, the shear zone is overlain by a dioritic intrusive mass and underlain by andesitic metavolcanics rocks. The shear zone and mineralization range in thickness from several metres to over twenty metres. The planned stopesfor the C1 Underground are generally located in areas where the shear zone is thickest and contains the highest gold grades.
