SBB Sabina Gold and Silver Corp

Sabina Gold & Silver Corp. (“Sabina”) or (the “Company”) (SBB – TSX/ SGSVF - OTCQX) provides an update on advancements of the Goose Mine development at the Company’s 100% owned Back River Gold District in Nunavut, Canada. The Goose Mine is the Company’s first mine on the 80 km long Back River Gold District, a multi-generational mining district with a demonstrated high-grade world class gold endowment.

“Completion of the 2022 summer sealift enables us to maintain our planned schedule for full construction to commence in 2023,” said Bruce McLeod, President & CEO. “With the sealift complete, we are now preparing for 2023, which includes the construction of our Winter Ice Road to transport equipment and supplies to the Goose site early in the spring of next year. Civil works are complete at the plant lay down area and we are ready for foundation preparation in advance of concrete and steel erection next summer. Pre-stripping continues at the Echo pit with the first ore encountered. We are excited to advance full construction of our initial mine on the Back River Gold District.”

Procurement & Sealift

A major component of the Company’s de-risking strategy for the Project focused on early procurement which has mitigated against cost escalation pressures and supply chain backlogs. By July 2022, the Company had made commitments for approximately 75% of the total Project procurement: the focus being on priority construction items for delivery on this year’s sealift. These items include equipment and supplies for site concrete work and the erection of plant and ancillary building shells and building envelopes. The 2022 sealift program included vessels from both the East and the West shipping hubs at Becancour and Hay River respectively.

For the 2022 sealift, Sabina shipped and received approximately 12,500 million tonnes (“MT”) of dry goods via 2 cargo vessels and 8 ocean barges, mainly comprised of:

• the balance of the phase 1 permanent accommodation / kitchen dining / administration complex (280 person);
• Construction offices and equipment;
• Bulk construction materials (cement, rebar and all building envelope structural steel);
• Select discipline construction materials (piping, electrical cable and tray, tanks, chutes, conveyors, etc);
• Building OH cranes, Emulsion plant, main generators;
• Ancillary buildings, additional fuel storage capacity, mining fleet spares; and
• Additional WIR equipment and mining equipment.

In addition, Sabina successfully completed the delivery and offloading of 9.2 million liters of bulk diesel fuel into our storage tank at the Port Facility.

As previously reported, Sabina has also procured its permanent 500 bed accommodation facility with the first phase of 280 beds delivered to the Port Facility already which is greater than camp personnel requirements for 2023. The remaining 220 beds required for operations were scheduled to be delivered this year but with the delayed start of the sealift from the west due in part to flooding in Hay River this Spring, the balance of the camp was not delivered. Should overflow be required in 2023, Sabina can utilize its existing 100 bed exploration camp at Goose.

Approximately 2,301 MT of the 3,400 MT of cargo marshalled for delivery from the West, was deemed as critical to schedule. Sabina received approximately 2,283 MT of critical cargo at the Port Facility in 2022, also due to the delayed sealift start. The remaining 18 MT of priority cargo needed is comprised of structural steel and welding consumables for the additional 15M liter fuel farm tanks to be constructed at the Port Facility and Goose. These remaining items can be delivered to site via air.

Committed purchase orders have been issued for all long-lead time packages (with 10 weeks or longer delivery) and the Project is now ~90% procured, with a target of 95% of all packages to be committed to by the end of November 2022.   Winter Ice Road (“WIR”)

Sabina has executed a construction and maintenance contract with Nuna Logistics for the 2022/2023 Winter Ice Road. Nuna is the largest Inuit-owned heavy civil construction, earthworks and winter ice road contractor in Canada.   Since 1993, Nuna has constructed the majority of Nunavut’s and the Northwest Territories’ exploration and mine site ice access roads. Their in-depth knowledge of northern operations enables them to mobilize, build, and maintain the reliable infrastructure required for continuous, cost-efficient operations in isolated regions of Northern Canada.

Preparations for Sabina’s WIR are underway with double headed construction (from the Port Facility and the Goose site) of the road to begin in December 2022. Transportation operations are expected to start in February 2023 with an anticipated 1500 loads being moved from the MLA to Goose.

Underground Development

Underground development continues to advance with approximately 1,200 meters complete and the first lateral access to the Umwelt Zone commencing. Preparations for development of the first ventilation raise have begun as well as underground exploration drilling of the Umwelt zone.

2023 Construction Preparation

Planned construction activities in 2023 will focus largely on building envelopes/frames and perimeter concrete. However, with procurement now substantially complete, Sabina intends to evaluate the detailed construction schedule and identify possible improvements to the timing for the delivery of specific work scopes.

2023 is going to be a busy year and Sabina is already planning construction activities such as:

• continued pre-development stripping of Echo pit with waste/ore stockpiling;
• road network expansion;
• emulsion plant construction;
• construction of phase 1 primary pond water management facility;
• complexing of the permanent accommodation facility;
• completion of construction office facilities;
• batch plant assembly;
• building concrete works;
• building envelope erection;
• MSE wall construction;
• conveyor gallery placement; and
• arctic corridor placement.
