Sabina Gold & Silver Corp. announced additional high-grade assay results from the final drill holes of the 2022 spring drilling program at the Goose Property on its 100%-owned Back River Gold Project (“Back River” or the “Project”) in Nunavut, Canada. The goal of this eight-hole drilling program focused at the V2 Zone at Umwelt was to better define the high-grade continuity of areas within the existing resource envelope near the interface of the planned open pit and upper portions of the underground.

This year's drilling has demonstrated that the higher grade of the V2 zone has been extended up plunge into the lower portions of the open pit. The added confidence in this higher-grade mineralization will serve towards informing optimization of the Umwelt mine plan. All drill holes encountered intervals of significant gold mineralization.

Select highlights from this drilling include: 12.59 g/t Au over 45.05 m including 21.33 g/t Au over 23.15 m, and 30.38 g/t Au over 8.00m in drill hole 22GSE607; 21.87 g/t Au over 15.10 m including 46.40 g/t Au over 4.20 m in drill hole 22GSE610; and 12.64 g/t Au over 20.35 m, and 16.22 g/t Au over 10.57 m including 40.00 g/t Au over 3.90 m, and 7.41 g/t Au over 12.60 m including 20.86 g/t Au over 4.00 m in three sequential zones in drill hole 22GSE611: Initial V2 Zone drilling in 2020 tested the upper portions of the Umwelt underground as part of a program to test the hypothesis of a high-grade corridor from the bottom of the pit down plunge to the high-grade Vault Zone (drilled in 2018/19). Drilling is still required to test continuity of the structure between the Vault and V2 zones. Between 2020 and this current program, the V2 zone has been tested by 14 additional drill holes which have better defined and added confidence to the continuity of higher-grade mineralization over a plunge length of 365 m. Sabina's focus on the Umwelt deposit with drilling, core review, detailed modelling and structural interpretation over the last several years has yielded strong exploration and optimization opportunities, both at the deposit, property, and belt scales.

Geological learnings have driven positive resource growth and optimization at the Umwelt, Llama and Goose Main deposits, and generated exploration opportunities resulting in the discovery of the Nuvuyak resource and evolution of the Hook zone towards future growth as a possible new resource. Results from drilling in 2022 will add to the confidence in the continuity of the higher-grade gold mineralization and thus offer opportunity for design adjustments and potential engineering optimizations of the pit wall, crown pillar, and underground sills. Drilling of holes 22GSE605, 22GSE606, 22GSE607, 22GSE608, 22GSE610, 22GSE611 and 22GSE613 largely targeted the intersection of the Quartz Feldspar Porphyry with the Lower Iron Formation within the short limb of the antiform/synform system; a plunging structure with significant width, of particularly high-grade gold mineralization.

Understanding and supporting mineralization continuity down plunge through this zone is important for forward planning and expansion, since the deposit is open along limbs and at depth. Drill hole 22GSE609 intersected the anticline hinge outside of the main V2 core and in an area where no reserves are contemplated. The significant length of the intercept at 26.85m with a grade of 5.80 g/t Au, including 11.71g/t Au over 9.25m demonstrates the strength of the mineral system in this structurally favorable setting.

Exploration of this setting will be advanced later this year in future drilling programs accessed from the exploration decline. The mineralization intersected by the 2022 drilling conforms to the general characteristics of the stronger gold zone examples at the Goose project. The host iron formation shows moderate to strong chlorite, actinolite and silica alteration with pervasive quartz veining and locally strong occurrences of pyrrhotite and arsenopyrite.

Visible gold occurrences are locally common in the host rock and along the stronger zones of sulphide mineralization, and are often associated with the higher-grade gold zones.
