Vancouver, BC – Sabina Gold & Silver Corp (SBB.T/SGSVF.OTCQX), (“Sabina” or the “Company”) is pleased to announce further results from drilling in the upper portions of the high-grade corridor at Umwelt Underground on its 100%-owned Back River Gold Project (“Back River” or the “Project”) in Nunavut, Canada.

Assay results from two new drill holes include: hole 20GSE575C which returned 19.89 g/t Au over 32.20m, including 51.50 g/t Au over 8.20m, and hole 20GSE574 which returned 5.88 g/t Au over 20.10m. These strong Umwelt underground results are in addition to the assays from the first three drill holes that included 15.15 g/t Au over 19.40 m (hole 20GSE571), 12.64 g/t Au over 7.70m (hole 20GSE572) and 13.72 g/t Au over 12.00m (hole 20GSE573), see the news release dated August 20, 2020.

Results continue to support the thesis of the continuity of a high-grade corridor extending from the high-grade Vault zone at depth to the lower limits of the current Umwelt open pit design. Additional drilling at this target is underway with results to be released as they become available.

“The assay results from drill hole 20GSE575C rank as one of the best ever encountered on the project in terms of grade and thickness.” said Bruce McLeod, President & CEO. “The intercept results we are now getting in the upper portions of the Umwelt high grade corridor are over twice the grade of the Umwelt underground resource. The tenor and robustness of gold mineralization we are seeing in this area just below the proposed Umwelt pit are very similar to the intercepts from Vault, approximately 600m down plunge. We are very encouraged by these continued exceptional results that, with more drilling, we believe will enable modelling of higher-grade material to be released earlier in the mine life. This adjusted mine sequencing could have a significant positive impact on what is already a tier one Project. More drilling is currently underway to better delineate these high-grade zones which could improve the grade in our resource and reserve estimates. To further support this drilling, we are preparing to drive an underground exploration ramp to access these areas from underground.”

Both drill holes in this release targeted an area surrounding a key feature that is demarked by a quartz feldspar porphyry dyke in intersection with an interpreted early structural setting within the Lower Iron Formation. The intersection lineation created by these components appears to be spatially associated with a high-grade structure. Drill hole 20GSE575C is located approximately 150 m down plunge from the planned open pit, and 45m down plunge from drill hole 20GSE573. Drill hole 20GSE576 is located approximately 150m down plunge of drill hole 20GSE572.

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 is 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 (Figure 1).

Mineralization intersected by drill hole 20GSE575C is exceptional and is an excellent example of many of the best features characterizing Back River gold zones. Iron formation consists of moderate to strong chlorite and silica altered bands with pervasive quartz veining hosting common sulphides of pyrrhotite and arsenopyrite occurring heavily throughout the zone. The interval from 303.70 m to 311.90 m contains an increase in coarse-grained, euhedral, bands of arsenopyrite up to 10% locally over 8.20 m that correlates with an internal strong gold grade of 51.50 g/t over 8.20m within a larger scale zone. Drill hole 20GSE574 similarly intersected a significant section of well altered iron formation with significant pyrrhotite mineralization and also hosts increasing arsenopyrite mineralization towards the lower contact of the zone. Visible gold was observed in all holes targeting the Umwelt underground reported to date.

Drilling is designed to delineate and detail the nature of a high-grade structure, which has never been discretely targeted. Drilling now continues in a second phase at Umwelt with an additional three to five drill holes.
