Summa Silver Options Property Within Historic Mogollon Silver-Gold Mining District from Allegiant Gold

VANCOUVER, Aug. 24, 2020 - Summa Silver Corp. ("Summa" or the "Company") (CSE: SSVR) (Frankfurt: 48X) is pleased to announce that is has signed a definitive agreement to earn up to a 100% interest in a dominant land position in the historic Mogollon silver-gold mining district (the "Property") of southwestern New Mexico from Allegiant Gold Ltd. ("Allegiant") (TSXV: AUAU).

Key Mogollon Property Highlights

• Significant historic production reported: Between 1904 and 1925 the district is reported to have produced 13.1M ounces of Ag and 271k ounces of Au from 1.39M tons of rock¹. Production stopped in 1942 due to the wartime cessation of all gold and silver mining in the United States.
• Near-mine discovery potential: The Property features poorly explored to completely unexplored veins with strong potential for further mineralization immediately surrounding historically producing high-grade mines (see attached figures).
• Blue-sky upside prospects: The Property hosts a number of undrilled veins with documented small-scale underground exploration workings that were driven above the main mineralized target elevation window. The depth projections of these veins represent strong conceptual drill targets.
• Historic exploration and underground data preserved: An extensive technical dataset is available and compilation for drill targeting is in progress.
• Mining critical to local economy: The economy of southwestern New Mexico is heavily reliant on mining and two large open-pit copper mines owned by Freeport-McMoRan are in operation within 90 km of the Property.

Galen McNamara, CEO of Summa Silver, stated: "Both the Tonopah and Mogollon districts represent two of the best discovery opportunities I've seen in my career. As shareholders, this deal effectively doubles our exposure to substantially under-explored districts with legacies of prolific historic production. I would like to thank Allegiant Gold and we look forward to aggressively pursuing both Hughes and Mogollon."

Peter Gianulis, CEO of Allegiant Gold, commented: "We are very excited to have reached an agreement with Summa. Their dedication and professionalism throughout this process was unparalleled and are confident we selected the right partner to develop one of the best undeveloped silver projects in the U.S. We look forward to their progress and our ability to focus on the development of Eastside, our flagship gold-oxide project in Nevada. "

Data Verification

The data disclosed in this news release relating to production and drilling is historic in nature. Historic production records for the Property are incomplete and are of unknown accuracy. Neither the Company nor the qualified persons are able to verify the historic production data and therefore investors should not place undue reliance on such data. The Company is unable to verify the data as drill hole rock samples are unavailable, precise drill hole collar locations are unknown, and down-hole survey data is incomplete. As such, the Company is treating the drill results as historical in nature and investors should not place undue reliance on such data. The Company's future exploration work will include verification of the data.

Exploration Plans

The Company is now beginning the data compilation, drill targeting, and permitting process with a view to be ready to drill in early 2021.

About Summa Silver Corp

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