Sabina Gold & Silver Updates Site Development and Exploration Activities at the Back River Gold Project - Seite 2

Project Development

Project development work at Goose will focus on detailed engineering, procurement, completion of select earthworks at the Port and Goose site and commencing the development of the underground ramp for exploration of the Umwelt deposit.

Detail engineering will advance on the crushing and screening plant, process plant, power house, truck shop and the Goose site fuel farm design. Detailed engineering should be largely competed in H2, 2021.

Additionally, Sabina is working to complete detailed design for the plant site pond; rough grade for the process plant; fuel farm pad; water management structures; and accommodation complex design. As part of this work the Company is also evaluating optimization opportunities on the sequencing of underground and open pit mining.

The exploration ramp, will involve establishing the on-surface support facilities, collaring the 5 m x 5 m portal and driving toward the Umwelt underground to provide for continued exploration of the Umwelt Zone.

Procurement items include phase one of the accommodation complex ~(278 rooms); steel and cladding for the process mill building and truck shop; multiplate steel tunnels for crushed ore reclaim; construction equipment required for foundation installation and building erection; secondary cone crusher, crusher screen and grizzly feeder; and phase one of the open pit mining fleet. These items will enable Sabina to be well prepared to begin pre-stripping of the Echo open pit once funding is obtained and a production decision is made.

Sabina is also actively working with a logistics specialist (Air- and Sea-lift) to finalize the execution strategy for goods and equipment to site.

Construction activities will continue with civil works including; construction of bulk fuel storage tank and containment at the Goose Site; completion of the fuel containment berm at the Port; advancement of the underground exploration ramp development at Umwelt; completion of infrastructure to support ramp activities, including a surface workshop for equipment maintenance, and water storage settling pond. This field season includes a geotechnical drilling program to provide additional information for water management structures.
