Sabina Gold & Silver Announces Significant Progress on Activities at the Back

River Gold District

Vancouver, BC - Sabina Gold & Silver Corp (SBB.T/SGSVF.OTCQX), ("Sabina" or the "Company") is pleased to report on progress on pre-construction activities for its proposed Goose Mine on the 100%-owned Back River Gold Project ("Back River" or the "Project") in Nunavut, Canada

"Tremendous work has been completed during the first nine months of 2021 as we propel the Project towards a production decision," said Bruce McLeod, President & CEO "We have been advancing the underground exploration ramp at Umwelt, have completed critical civil works at the Goose site, and have prepared the Sabina Port facility to receive the largest sealift planned to date, which is now offloading the first ship. We have also completed detailed engineering and received issued for construction drawings for the process plant. In parallel we continue to work towards Project financing in order to make a production decision."

Our Back River camps are working safely under Sabina's COVID-19 Protocol Operational Framework. Sabina continues to engage with relevant authorities to modify protocols based on new information to ensure our measures are protective. Testing remains in place for all upon deployment and once on site. To date there have been zero cases of COVID-19 or any variants at camp.

Over the last 17 months, as a result of Territorial regulation, Sabina has been unable to utilize any of our Inuit employees. For those long-term employees, we have maintained a food support program during this time. The Company is now in discussions with the Government of Nunavut and the Government of Northwest Territories on a back to work program that will safely see our Inuit employees back at work at Back River in the near future.

Project Development Update

Engineering and Procurement

Sabina has continued to advance engineering activities for the plant process component and has now finalized these issued for construction ("IFC") packages with Sacre Davey. The Company has also progressed detailed engineering on the balance of the plant and ancillary facilities.

Additionally, detailed engineering design for the Goose fuel farm is complete. Detailed design of site-wide water management structures such as the plant site pond, emergency discharge pond and creek crossings are anticipated by the end of 2021.

Sabina has also advanced vendor certified engineering drawings ("CE") packages with FLSmidth for all process plant equipment, Toromont for the main power generation and Industrial Equipment Manufacturing for conveyor and tower packages. A contract to provide drawings for the recently purchased permanent accommodation complex is also underway. Armtec Inc. has been contracted to design and supply a multiplate tunnel feature below the fine ore stockpile. In addition to the CE drawings FLSmidth is providing, Sabina has procured several long lead items for the crushing plant, all enroute to the Port Facility via the current sealift program.

The Company has submitted all IFC packages to CGT Industrial, a prominent Arctic constructor, who are completing their scope and constructability review which will culminate in a fixed price lump sum bid with price certainty on all direct & indirect manhours with a commodity rise & fall mechanism. The rise and fall mechanism is required at this time due to current market volatility, remaining vendor pricing validity and timing of project financing. Tentative submission of this proposal is expected at the end of Q3 2021.

Sabina has purchased the design packages for the process plant and truck shop structures along with associated cranes and materials, which are enroute to the Port facility via the sealift program.

Sabina has also procured the phase 1 open pit mining equipment required for early stripping which has the first pieces have now arrived at our Port facility.

Sabina's procurement strategy in 2021 has focused on supporting the following critical path activities, which are targeted to be completed in 2022:

1. Have sufficient civil works completed such that concrete foundations can be commenced for the process plant and truck shop, and that the permanent camp laydown area is of sufficient size to install the permanent camp complex;
2. Have all equipment in place by YE 2021, in preparation for a decision to commence construction of a winter ice road, working from both the Goose and Port sites; and
3. Ensure the open pit mining fleet is available to begin work in Q2 2022.

Umwelt Exploration Ramp

After the successful completion of the box cut for establishing a portal face, Sabina's underground ("UG") exploration decline team focused on establishing services and commissioning of the mining equipment utilizing the newly erected portal area workshop. Sabina's first UG portal blast occurred on May 31st and underground development is well underway with the portal entrance and 130 meters of development completed by Sabina's development crews.

Sabina has completed the UG workshop and dry storage areas. The heated workshop is equipped with a dedicated generator system and mine load centers used to power the underground development, a compressed air system, offices, tool crib, hose fabrication room and a worker's dry.

Pre-development Construction Activities

Sabina's site crew and earthworks contractor have focused on upgrading roads, infrastructure, building laydown pads and crushing and screening activities. To date, 10,000m3 of esker material has been harvested from a nearby site location which will be used for the preparation of concrete aggregates and pond liner underlay.

The earthworks contractor is a Kitikmeot qualified business and has been engaged to complete the drill/blast rough grading program at the plant site area. The team is currently moving ahead with the rough grading of the plant site area, and pad area for permanent fuel storage tanks which will eventually be used to store fuel for the entire site.

Sealift

Sabina's sealift this season is in excess of 25,000 revenue tons, including two vessels from Becancour, Quebec and six barges from Hay River, NWT. At the consolidation points, the team successfully completed the collection and seaworthy packaging of all equipment to ensure safe transport. The vessels and barges are in motion and the first ship has reached the Port facility and has commenced offloading operations. To facilitate the sealift, Sabina has prepared laydown storage areas at and fuel tank containment at the Port site with all sealift activities anticipated to be completed by the end of September.
