Sabina Gold & Silver Reports Results From First Two Drill Holes Demonstrating Additional High-Grade Mineralization at Umwelt.

Press Release

May 11, 2022

Results include 13.68 g/t Au over 31.90m, including 30.98 g/t over 9.90m in drill hole 22GSE605, and 11.93 g/t Au over 41.45m, including 32.00 g/t over 8.00m in drill hole 22GSE606

Vancouver, BC – Sabina Gold & Silver Corp (SBB.T/SGSVF.OTCQX), (“Sabina” or the “Company”) is pleased to announce initial results from the recently completed Umwelt drilling program on its 100%-owned Back River Gold Project (“Back River” or the “Project”) in Nunavut, Canada.

This eight-hole drilling program at Umwelt targeted select areas near the interface of the planned open pit and upper portions of the underground where potential exists for optimization of the mine plan.

Assays for the first two drill holes include: 13.68 g/t Au over 31.90m, including 30.98 g/t Au over 9.90m in drill hole 22GSE605, and 11.93 g/t Au over 41.45m, including 32.00 g/t Au over 8.00m in drill hole 22GSE606. Results from drill hole 22GSE605 demonstrate the excellent potential for additional mineralization outside of the current mine plan, and drill hole 22GSE606 highlights the continued opportunity for optimization of the current resource model. See Table 1.0 below for details.

These new assays continue to support the continuity of higher grade portions of mineralization modeled in the resource and further defined by previous drilling completed at the V2 zone that have returned significant intercepts such as 19.89 g/t Au over 32.20m in hole 20GSE575C, including 51.50 g/t Au over 8.20m (see news release dated September 3rd, 2020), 20.02* g/t Au over 20.55m in hole 20GSE581, and 23.52* g/t Au over 22.75m in hole 20GSE582 (see news release dated October 13th, 2020). (*weighted averages include uncapped assay results).

Six of the drill holes (results pending) tested mineralization within the resource envelope over a plunge extent of 200m with vertical distance from surface ranging between 115m and 200m. Two additional drill holes were completed; one tested the anticline structure to the west of the high-grade corridor and outside of current planned underground mining areas, while a second was completed as a geomechanical test within the open pit. Planned drilling for the Hook zone, announced as part of this drilling program, was deferred.

“We continue to demonstrate and better define these structures that are two to three times the average grade of the current Umwelt underground reserve,” said Bruce McLeod, President & CEO. “This current drilling follows on the strong results of drilling completed in 2020 at the Umwelt V2 zone, continuing to support the value of advancing the exploration ramp for better access to evaluate, grow and optimize this higher-grade material, which if accessed earlier in the mine life could improve already robust project economics.”

Umwelt Underground and High-Grade Corridor Drilling

Sabina’s focus on the Umwelt deposit with drilling, core review, detailed modelling and structural interpretation over the last six years has yielded strong exploration and optimization opportunities, both at the deposit, and across the Goose Property. 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 better inform portions of the higher-grade gold continuity and assist with design adjustments and potential optimizations of the pit wall and crown pillar design. A set of six drill holes 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 (see Figure 1.0). 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 22GSE605, targeting the intrusion of a Quartz Feldspar Porphyry Dyke through the Lower Iron Formation, intersected over 30m of mineralized iron formation, with a 10m interval of particularly robust mineralization characterized by heavily disseminated arsenopyrite, disseminated to semi-massive pyrrhotite, and several occurrences of visible gold. This interval corresponds with assays that returned 30.98 g/t Au over 9.90m, within a larger scale zone of strong gold mineralization. This intercept is situated immediately below the current planned open pit, and 10 m up-dip of the planned stopes, in the permanent crown pillar; an area not currently included in the estimated Reserves.

Drill hole 22GSE606, located approximately 100m down plunge of 22GSE605, targeted the intrusion of a Quartz Feldspar Porphyry Dyke through the Lower Iron Formation, within the current planned underground workings, to further test the continuity of the high-grade V2 gold zone. Much like hole 22GSE605, the drill hole intersected over 40m of well mineralized iron formation, with an 8.0m interval of particularly robust mineralization characterized by heavily disseminated arsenopyrite, disseminated to semi-massive pyrrhotite, and several occurrences of visible gold.

True width of the mineralized iron formation in both drill holes is closely represented by the intersections presented in Table 1.0, as drilling is nearly perpendicular to the short limb of the antiform/synform set.
