Vancouver - Sabina Gold & Silver Corp (SBB.T/SGSVF.OTCQX), ('Sabina' or the 'Company') is pleased to announce further high grade assay results from drilling of the upper portions of the high-grade corridor at the Umwelt Underground resource (the 'V2 Zone') on its 100%-owned Back River Gold Project ('Back River' or the 'Project') in Nunavut, Canada.

Internal studies conducted earlier this year suggest that mining higher-grade underground material at the beginning of the mine life could have a significant positive impact on project economics by increasing gold production in the early years. Drilling was designed to delineate and detail the nature of the high-grade structure at Umwelt, which has never been discretely targeted. During the 2020 field program, nine holes were drilled, proving the hypothesis that additional high-grade corridors exist between the Vault Zone at depth and the bottom of the proposed open pit at Umwelt.

This year's drilling focused on a zone directly under the proposed Umwelt open pit (V2 Zone) at a depth that ranges from 135m to 285m below surface, over a plunge extent of approximately 300 m. All seven drill holes targeting this zone returned exceptional widths of gold mineralization, up to 2-3 times the average grade of the Umwelt underground reserve. The V2 Zone is very similar to the Vault Zone, further supporting the concept of additional high-grade underground corridors within the Umwelt deposit. These results will be incorporated into an updated Feasibility Study expected to be released in the 1st Quarter of 2021.

To further explore the high-grade corridor at Umwelt, the Company is moving forward with an underground exploration ramp that can facilitate further exploration drilling as well as provide for bulk sampling. The exploration ramp could provide early access to continue exploring the V2 Zone with approximately 1500m of ramp development. The initial surface work and mobilization of equipment required to support the exploration ramp is underway, with collaring of the decline expected in early 2021.

These assay results are the final three holes from the V2 Zone and include: hole 20GSE581 which returned 16.59 g/t over 20.55 m hole 20GSE582 which returned 14.78 g/t over 22.75 m and hole 20GSE584 which returned 14.78 g/t over 24.80 m.

Highlights from previous drilling at V2 as reported includes 15.15 g/t over 19.40 m in hole 20GSE571 and 19.89 g/t over 32.20 m in drill hole 20GSE575C.

'The consistent widths and high grades returned to date from our V2 Zone highlight and confirm upside to the Umwelt underground resource,' said Bruce McLeod, President & CEO. 'this could enable an optimization to our mine sequencing, enhancing the economics of an already robust project as well as provide the opportunity to increase the production profile in the early years of the mine life. The Company intends to incorporate these results into an updated Feasibility Study to be completed in Q1, 2021. Currently Sabina has commenced civil works to prepare for collaring of the exploration ramp next spring for the purpose of accelerating additional underground drilling to further define opportunities at the Umwelt underground.'

Umwelt Underground and High-Grade Corridor Drilling

Sabina's focus on structural studies over the last three years has yielded strong exploration opportunities across the Goose Property and driven positive resource optimization and growth at Umwelt. As part of this focused approach, drilling in 2020 was committed to better define the continuity of higher-than-average-grade potential within the Umwelt underground over approximately 815 m of plunge length that extends north from the Vault zone towards the boundaries of the Umwelt Open Pit.

Mineralization intersected by drill holes 20GSE581, 20GSE582 and 20GSE584 continues to demonstrate the exceptional tenor of mineralization associated with the Umwelt gold structures and is an excellent example of many of the best features characterizing Back River gold zones. Iron formation consists of moderate to strong chlorite, actinolite and silica alteration with pervasive quartz veining hosting common sulphides including pyrrhotite and arsenopyrite occurring heavily throughout the zone. These three drill holes are excellent examples of the robust mineralization style that includes heavy sulphidation of the host rock with exceptional grade occurring proximal to the lower contact of the iron formation units. Rheologic contrast of the stratigraphy and high-iron content of the host horizon are interpreted as favourable features in establishing high quality deposits at Back River. Visible gold was observed in all holes targeting the Umwelt underground V2 Zone reported to date.

Sabina Gold & Silver Corp.

Sabina Gold & Silver Corp. is well-financed and is an emerging precious metals company with district scale, advanced, high grade gold assets in one of the world's newest, politically stable mining jurisdictions: Nunavut, Canada.

Sabina released a Feasibility Study on its 100% owned Back River Gold Project which presents a project that has been designed on a fit-for purpose basis, with the potential to produce 200,000 ounces a year for 11 years with a rapid payback of 2.9 years.

The Project received its final Project Certificate on December 19, 2017. The Project received its Type A Water License on November 14, 2018 and its listing to enable deposition of tailings on Schedule 2 of the Metals and Diamond Mining Effluent Regulations on June 25, 2020. The Company is now in receipt of all major authorizations for construction and operations.

In addition to Back River, Sabina also owns a significant silver royalty on Glencore's Hackett River Project. The silver royalty on Hackett River's silver production is comprised of 22.5% of the first 190 million ounces produced and 12.5% of all silver produced thereafter.
