SUMMA SILVER COMMENCES DRILLING AT THE HUGHES HIGH-GRADE SILVER-GOLD PROJECT, TONOPAH, NEVADA

Summa Silver Corp. has commenced an exploration drill program at the high-grade silver-gold Hughes project near Tonopah, Nev.

Key Highlights:

• Drilling has commenced: A reverse-circulation drill rig has been mobilized to site and is currently advancing the first hole of the program. A core rig is also on-site and will be drilling core tails on select holes.
• High-Potential Targets: Five targets will be tested and a minimum of seven holes are planned. Targets were selected based on thorough interpretations of geophysical, geochemical, and geological mapping data acquired by the Company (see attached figures).
• Additional Drilling at the Ruby Discovery: Representing the extension of the Tonopah District and located 1.3 km east of the Belmont Mine, this discovery will be tested with aggressive step-outs.
• Mineralization already intersected at Ruby: The three holes drilled by the Company at Ruby in 2020 and 2021 all intersected zones of quartz veining, alteration and intermittent mineralization with features strikingly similar to the ore bodies in the heart of Tonopah district (see previously released core photos from SUM21-49 here and the Company's press releases dated December 17, 2020 and March 3, 2022).
• New Targets include Emerald, Diamond, Sapphire, and Topaz: These four new target areas, which were previously unrecognized, represent significant discovery opportunities just outside of the historic Tonopah mining district.
• Fully Funded: The Company remains fully funded with approximately $10.5 million in working capital.

Galen McNamara, CEO, stated: "The targets we will be drilling at the Hughes Project this season were developed from a systematic, multi-layered approach which included detailed interpretations of structural geology, geophysics, and geochemistry. In our opinion, its very rare that compelling undrilled targets can still exist within sight of a prolific historically producing mining district like Tonopah. The five targets we will be drilling at the Hughes Project this spring and summer represent opportunities for significant new discoveries that the team has been very much looking forward to testing for some time."

Hughes Exploration Drill Program

The focus for this phase of exploration drilling is on testing previously undrilled epithermal vein targets identified by Summa over the course of multiple ground-based exploration programs (Figure 1). The targets are all east of the historic Tonopah mining district and will be tested using both reverse circulation (RC) and core drilling methods in a minimum of seven holes.

Four main target areas will be tested over the course of the program, and include:Ruby: The Ruby discovery has been drilled by the Company in three holes completed in 2020 and 2021 (see Figures 1 and 2). The area is characterized by a broad zone of pyrite-rich, phyllic alteration transitioning to strong argillic + silica alteration peripheral to a wide zone of strong epithermal-related gold and silver mineralization hosted in quartz-rich breccias and veins. All three holes intersected zones of local mineralization highlighted by hole SUM20-10 which intersected 469 g/t silver equivalent (258 g/t Ag and 2.63 g/t Au) over 2m (see the Company's press release dated December 17, 2020). Subsequent 3D IP geophysical survey work identified coincident chargeability and resistivity anomalies immediately along strike to the east of the drilled area. The coincident anomalies are interpreted to represent broad zones of sulfide-rich, quartz-dominant hydrothermal-related alteration. Modelling suggests an east-west trend to the structural zone. Drilling will investigate the eastern strike-extent of Ruby mineralization and the exploration target is an extension of the Tonopah district.

At Ruby, two holes are planned to be drilled with RC (reverse circulation) pre-collars followed by core tails through the target zones. At the other targets, four holes are planned to be drilled via RC. A pXRF (portable Xray fluorescence) instrument will provide close to real-time geochemical data focused on key pathfinder elements (e.g., arsenic, antimony, lead, zinc and copper). Based on these early results, additional holes may be drilled.

About Summa Silver Corp

Summa is a Canadian junior mineral exploration company. The Company owns a 100% interest in the Hughes project located in central Nevada and has an option to earn 100% interest in the Mogollon project located in southwestern New Mexico. The Hughes project 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 Mogollon project is the largest historic silver producer in New Mexico. Both projects have remained inactive since commercial production ceased and neither have seen modern exploration prior to the Company's involvement.
