Summa Silver Mobilizes Drills to the Hughes Property; Files NI 43-101 Technical Report

VANCOUVER, June 30, 2020 - Summa Silver Corp. ("Summa Silver" or the "Company") (CSE: SSVR) (Frankfurt: 48X) is pleased to announce that mobilization of drilling equipment to the Hughes Property is in progress. Additionally, the Company has filed an independent Technical Report for the Hughes Property on SEDAR.

Drill Program Update:

• Drill Mobilization Underway: The Company is currently mobilizing one reverse-circulation drilling rig and one core drilling rig to the Hughes Property.
• Drilling Imminent: The summer drill program will consist of a minimum of 7,500 m of drilling in approximately 15 holes (see news release dated June 25, 2020).
• First Modern-Day Exploration: The first drill holes will test the immediate area of 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, but has never been systematically explored.
• 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 potentially mineralized structures.

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

Technical Report

An independent Technical Report for the Hughes Property has been filed on SEDAR. The Technical Report was prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects and includes a two-phased recommendation for up to 15,000 m of drilling on the property.

Donna Property Update

After careful review of all available data, the Company has elected to terminate the option agreement with Eagle Plains Resources (the "Optionor") in respect of the Donna Property. The property has been returned to the Optionor and the Company no longer has an interest in the Donna Property or any further obligations to the Optionor. Although the Donna Property is prospective for gold mineralization, the Company believes its resources are better spent on the Hughes Property in central Nevada, and on evaluating other potential projects with a view to maximize shareholder value.

Engagement of Swiss Resource Capital

The Company has engaged SRC Swiss Resource Capital AG ("SRC") to provide investor relations and communication services in Europe to increase exposure and awareness to investors especially in the German speaking financial community but also through their services provided in English worldwide. SRC, which is led by Jochen Staiger, CEO, will assist the Company's efforts in growing investor awareness and expanding exposure to retail and institutional investors by providing news dissemination and marketing services in German. In consideration for these services, the Company will pay SRC 5,000 CHF per month for a period of 12 months and has grated 100,000 stock options to SRC at a price of $0.92 per share with a five year term, vesting in stages over 12 months beginning on the 3 month anniversary of the issuance.

About Summa Silver Corp

Summa Silver Corp. is a Canadian junior mineral exploration company. The Company is focused on the Hughes Property located in central Nevada, which is host to the high-grade historically 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. A qualified person has not done sufficient work to classify this information as a current mineral resource estimate and the Company is not treating the historical production as a current NI 43-101 mineral resource.
