Summa Silver Provides Drill Program Update at Hughes Silver-Gold Property; Drilling Additional Targets

TORONTO, Sept. 15, 2020 - Summa Silver Corp. ("Summa" or the "Company") (CSE: SSVR) (Frankfurt: 48X) is pleased to provide an update to the on-going drill program at the Hughes silver-gold project in Tonopah, NV. To date, ten holes have been completed and two are in progress with two core rigs in full operation. Approximately 5,200 m have been drilled in completed holes. All holes drilled to date have intersected zones of quartz veins, stockworks and breccias.

Key Highlights

• First-Ever Drilling at the new Murray Target: This target is located on the western side of the property, where the claim boundary is within 300 m of Blackrock Gold's recently announced discovery in hole TW20-001 which intersected several zones of high-grade silver and gold mineralization (see attached figure). One hole is complete on the Murray Target and at least three additional holes are planned.
• First Modern Exploration of the Belmont Mine: Seven holes have been completed at the Belmont Mine, all of which were widely spaced and targeted different veins. Between 1903 and 1929 the Belmont mine was a major American silver producer.
• First-Ever Drilling at the Mizpah Extension Mine: Two holes have been completed at the Mizpah Extension Mine targeting up-dip and down-dip extensions of modeled veins that were only mined on a very small scale and had never been previously drilled.
• Follow-Up Drilling at the Ruby Target: One hole is in progress to test the area of hole ET-7, which is located 1.3 km east of the Belmont Mine and in 1989 is reported to have intersected silver and gold mineralization that has not since been pursued.

Galen McNamara, CEO, stated: "This drill program represents the first modern, and indeed first ever, drilling on much of the prolific historically producing Hughes Property. All holes drilled so far have intersected zones of quartz veins, stockworks and breccias. Due to high demand and related capacity limitations at the assay labs in Nevada, receipt of results has been slower than expected. Upon receipt of assays, the results will be compiled and released in a timely manner."

Murray Target

Newly added to the drilling plan, one hole has been completed at the Murray target, one hole is in progress, and at least two more holes are planned. This target area is located approximately 1.5 km west of the Belmont Mine and consists of a series of moderately north dipping vein horizons both between and down-dip from mapped underground development on multiple levels.

Belmont Mine Area

Seven holes have been drilled in the vicinity of the Belmont Mine. Each hole targeted strike and/or dip extensions of known veins and were widely spaced. The stacked and steeply dipping orientation of veins in the mine area meant that many of the holes tested multiple targets along their planned lengths.

Mizpah Extension Mine Area

Two holes have been completed in the area of the Mizpah Extension Mine targeting up- and down-dip of historic mine workings, and interpreted intersections between steeply and shallowly dipping faults. Small scale mining was done in 1914 on only one level in the Mizpah Extension Mine approximately 300 m below surface and 350 m east of the Belmont Mine. No prior drilling is known to have been done in this area.

Ruby Target Area

One hole is in progress at the Ruby target to follow-up on hole ET-7, which approximately 1,300 m east of the Belmont mine is reported to have intersected silver and gold mineralization. Of important note, ET-7 was drilled as a vertical hole. Three-dimensional modeling shows that the most prospective veins on the eastern portion of the property are steeply oriented or near vertical and therefore not appropriately tested with vertical drill holes.

About Summa Silver Corp

Summa Silver Corp. is a Canadian junior mineral exploration company. The Company has options to earn 100% interests in the Hughes property located in central Nevada and 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.

There are no assurances that the Company will achieve the same results for the Property as past producers. Past production figures of the Belmont Mine are historical and there are no assurances that the Company will be able to reconcile these to current NI 43-101 categories.
