Vancouver - Summa Silver Corp. ('Summa' or the 'Company') (TSXV: SSVR) (OTCQB: SSVRF) (Frankfurt: 48X) is pleased to announce additional high-grade silver and gold drill results from the Hughes Property at Tonopah, Nevada.

Rescue Veins of the Past Producing Belmont Mine

702 g/t silver equivalent (282 g/t Ag and 4.2 g/t Au) over 3.9 m from 360.3 m including 1,733 g/t silver equivalent (711 g/t Ag and 10.2 g/t Au) over 1.2 m from 363.1 m in SUM21-47 which is a 50 m step-out down-dip at Rescue.

Murray Target

4,116 g/t silver equivalent (2,009 g/t Ag and 21.1 g/t Au) over 0.4 m from 323.6 m and 303 g/t silver equivalent (138 g/t Ag and 1.64 g/t Au) over 4.1 m from 352.4 m in SUM21-37 which is a 75 m step-out up-dip and west at Murray.

1,200 g/t silver equivalent (560 g/t Ag and 6.40 g/t Au) over 0.8 m from 335.7 m in SUM21-39 which is a 50 m step-out down-dip at Murray.

The upper interval in SUM21-37 comprises the highest-grade mineralization intersected at Murray.

Note: silver equivalent (AgEq) based on 100(Ag):1(Au), true widths are unknown

Ruby Discovery and 2022 Drill Program

The Ruby Discovery was first drilled by the Company in 2020 and represents a 3 km step-out along strike from the historically producing Tonopah Mining District

Assays are pending for two step-out holes in this area and both holes have intersected quartz-adularia veins and breccias featuring visible Ag-sulfosalt mineralization which remain open in all directions.

High-grade silver and gold mineralization has now been identified in multiple zones over 3.5 km at Hughes and the property features a number of coincident un-explored geophysical and geochemical anomalies representing high-priority targets.

Drilling at Hughes is now complete for 2021. The Company is currently planning a significant 2022 drill program to both expand zones of known high-grade mineralization and drill un-explored high-priority targets.

Galen McNamara, CEO, stated: 'In less than two years since founding the Company we have now drilled multiple zones of strong mineralization over 3.5 km at the Hughes Property in Nevada. Additionally, surface exploration has revealed that the property features totally un-tested and high-priority targets, several of which are along immediate trend from one of the most prolific and famous historic silver districts in the US. Substantial amounts of drilling are required both here and on our Mogollon Property in 2022 as we drive towards mineral resource estimates. I anticipate that strong mineralization will be intersected regularly as drilling continues.'

About Summa Silver Corp

Summa Silver Corp is a Canadian junior mineral exploration company. The Company owns a 100% interest in the Hughes property located in central Nevada and has an option to earn 100% interest in the Mogollon property located in southwestern New Mexico. The Hughes property is host to the high-grade past-producing Belmont Mine, one of the most prolific silver producers in the United States between 1903 and 1929. The mine has remained inactive since commercial production ceased in 1929 due to heavily depressed metal prices and little to no modern exploration work has ever been completed.
