Summa Silver to Begin 7,500m Summer Drill Program at the Hughes Silver Project, Nevada with Multiple Drill Ready Targets

VANCOUVER, June 25, 2020 - Summa Silver Corp. ("Summa Silver" or the "Company") (CSE: SSVR) (Frankfurt: 48X) is pleased to announce that is has finalized plans for a 7,500-metre summer drill program at it's Hughes Property in Central Nevada. The program will be surface based and consist of both reverse circulation (RC) and core drilling in approximately 15 holes beginning in early July.

The Company's historically producing Belmont Mine, which is reported to have produced 36.7M ounces of high-grade silver and 428,000 ounces of gold¹, has never been systematically explored with modern exploration techniques. Geological modelling indicates that many of the veins that were mined are open at depth and along strike.

With the recently completed $5M financing, the Company is fully financed for this first round of modern-day exploration on the project.

Key Highlights

• High Potential Targets: Targets were selected based on extensive three-dimensional modeling of the geology, faults, veins and underground workings of the historic Tonopah District (see attached figures)
• First Modern Exploration of the Belmont Mine: Drilling will target veins that remain open along strike and down-dip in the Belmont Mine, which between 1903 and 1929 is reported to have produced 36.7M oz of silver and 428k oz of gold from 2.1M tons of rock¹. In addition, recently announced historic chip samples are reported to have returned grades between 501 and 3,253 g/t AgEq* over 0.6 m (see news release dated June 11, 2020).
• First-Ever Drilling at the Mizpah Extension Mine: Drilling will target up-dip and down-dip extensions of veins that are reported have carried grades between 225 g/t AgEq* over 1.2 m and 7,907 g/t AgEq* over 0.8 m² that remain undrilled to-date.
• Follow-Up Drilling at the Ruby target area: Angled drill holes will test the area of vertical hole ET-7, which in 1989 is reported to have intersected 1,587 g/t AgEq* over 0.9 m beginning 512 m downhole³.
• Multiple Targets per Hole are Planned: The stacked nature of the veins in the Belmont Mine area means that many of the planned holes will test multiple mineralized structures.
• Timing: A drill contractor has been engaged and mobilization of one RC rig and one core rig is scheduled for early July with drilling activities continuing for three to four months.

Galen McNamara, CEO, stated: "After a deep-dive into modeling and targeting of the Tonopah District geology, our Nevada-based team is excited to test our first targets. This 7,500 metre, 15-hole drill program represents a significant step towards assessing the remaining potential of the Company's Belmont Mine, where multiple veins remain open both along strike and down dip. Elsewhere on the Hughes Property, targets were selected based on historic results and those of past operators whose work identified zones of both high-grade mineralization and extensive hydrothermal alteration."

Belmont Mine (7-10 Holes)

Three broad areas will be drilled in the vicinity of the Belmont Mine. Each hole will target strike and/or dip extensions of known veins. Importantly, historic underground development on many of the veins was stopped at shallow levels well above the elevation of greatest dilation in the Belmont Vein, which was up to 15m wide¹ before it was mined. In addition, the tightly stacked nature of the veins in the mine area means that many of the holes will test multiple targets along their planned lengths.

Mizpah Extension Area Targets (2-3 Holes)

The first targets in the Mizpah Extension Mine area will be up- and down-dip from an area of historically mined material. Small scale mining in 1914 on only one level in the Mizpah Extension Mine approximately 300m below surface and 350m east of the Belmont Mine workings is reported to have encountered grades between 225 g/t Ag equivalent over 1.2m and 7,907 g/t Ag equivalent over 0.8m³.

Ruby Area Target (2-3 Holes)

At least two holes will be collared in this area to follow-up on hole ET-7, which approximately 1,000 m further east from the Mizpah Extension Mine workings is reported to have intersected 0.9 m of 1,587 g/t Ag equivalent beginning 512m downhole². Of important note, ET-7 was drilled as a vertical hole. Three-dimensional modeling shows that the most prospective veins on the Property are steeply oriented or near vertical and therefore not appropriately tested with vertical drill holes.

Drilling Methods

A mix of RC and core drilling is planned. Where expected to be barren, the upper parts of holes will be drilled with RC methods as pre-collars to depths of up to 250 m. Holes will then be completed through target zones with core drilling. Pre-collaring holes with RC is expected to result in significant time and cost savings, while completing holes with core methods will result in greater geological and assay certainty. The estimated depth of pre-collars is based on of the Company's geologic modeling.

About Summa Silver Corp

Summa Silver Corp. is a Canadian junior mineral exploration company. The Company's assets consist of the Hughes property located in central Nevada, and the Donna property located in central British Columbia. 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.
