High Grade Intersections From The Hughes Property

VANCOUVER - Summa Silver Corp. announced additional high-grade silver-gold intersections from the Hughes Property in central Nevada.  These results build on previously reported intercepts and demonstrate high-grade continuity along numerous high-priority veins. Results from this batch of assays are from three vein sets in the Belmont Mine target. Rescue Veins in the Belmont Mine Target Area: 2,995 g/t silver equivalent (1,480 g/t Ag and 15.15 g/t Au) over 0.8 m from 378.5 m in SUM20-19; and SUM20-19 is a 50 m step-out from SUM20-06 which intersected 3,760 g/t AgEq (1,762 g/t Ag and 19.99 g/t Au) over 2.5 m and a 50 m step-out from SUM20-20 which intersected 6,220 g/t AgEq (2,910 g/t Ag and 33.1 g/t Au) over 0.7 m. 725 and IOU Veins in the Belmont Mine Target Area: 1,269 g/t silver equivalent (580 g/t Ag and 6.89 g/t Au) over 0.7 m from 156.0 m in SUM20-28 (450 m northwest of the Rescue vein series); and 823 g/t silver equivalent (393 g/t Ag and 4.3 g/t Au) over 0.6 m from 395.8 m in SUM20-23 (250 m north of the Rescue vein series).

The Company is currently conducting a pre-drilling exploration program which includes an airborne LiDAR survey and geological mapping. Soil and induced polarization surveys focused on the eastern extension of the Tonopah District are also scheduled for this spring.

Galen McNamara, CEO, stated: "Multiple vein systems in the historic Belmont Mine continue to return exceptional grades with continuity now shaping up nicely. With this year's exploration now beginning, our focus will be on both mineral resource style step-outs, and discovery of additional strong mineralization on the eastern extension of what is one of the most heavily endowed silver districts in the United States."

The Phase I drill program in 2020 was designed to test the lateral and vertical extents of structurally controlled, epithermal-related, high-grade silver and gold mineralization historically mined in the Tonopah District. Nineteen holes tested numerous steeply-dipping, west-southwest striking veins and secondary splays in the Belmont Mine target area. At each vein location (e.g., Rescue, IOU and 725), a series of holes tested the along-strike and down-dip extensions of mineralization in approximately 50 m centered piece-points along the vein (see attached figures). In most cases, mineralization consists of locally Ag-sulfasalt bearing, banded to brecciated quartz ± adularia veins with associated argillic alteration halos hosted in intermediate to felsic volcanic and volcaniclastic rocks. Vein thickness varied from a few centimeters to a few meters. Assays for 5 holes are reported in Table 1 and results are still pending from 9 holes.

Phase II Program is a significant follow-up drill program is planned and will commence shortly. A drill contractor has been selected and program details will be released once targets are ranked and prioritized.

The company is currently flying a LiDAR (light detection and ranging) survey and are collecting high-resolution ortho-images over the entire project area. The data will be used to identify areas of historic disturbance potentially related to surface mineralization and to provide robust topographic control for future modeling and ground-based surveys. The company has also initiated a property-scale geological mapping program aimed at refining the geological model for the district. A focus will be on defining the footprint-extent of outcropping hydrothermally altered bedrock as well as mapping along key structures. Systematic rock-chip samples will be collected to aid in advancing the geochemical model for the district as well as defining new drill targets.
