Summa Silver Commences Drilling Across the Eastern Extension of the Prolific Tonopah Mining District, Nevada

Drilling is focused on evaluating the scale and continuity of significant silver-gold mineralization at the Ruby discovery

Vancouver, December 4, 2024 - Summa Silver Corp. (TSXV: SSVR) (OTCQX: SSVRF) (FSE:48X) ("Summa" or the "Company") is pleased to announce that exploration drilling has commenced at the Hughes Project, Tonopah, Nevada (the "Hughes Project"). Drilling is designed to test the highly-prospective eastern extension of the Tonopah Mining district starting at the significant Ruby discovery.

Key Highlights:

• Drilling has commenced: A reverse-circulation ("RC") rig is on-site at the Ruby target and currently advancing the first pre-collar hole of the program. A core rig is expected to arrive on site shortly and will complete each hole through the prospective target zones.

• Extension of the Tonopah District: Up to 7,000 m of drilling is planned between the Ruby and Sapphire discoveries located 1.3 to 4.2 km east of the edge of the Tonopah Mining District, the second largest historic silver producer in the State of Nevada (see attached figures).

• Chasing New Veins: Drilling is starting at the Ruby discovery with a series of step-out holes from high-grade mineralization discovered in previous drill programs, including:

  • 1,450 g/t silver equivalent* (8.41 g/t Au, 813 g/t Ag) over 3.0 m in SUM23-59

  • 430 g/t silver equivalent* (2.47 g/t Au, 243 g/t Ag) over 2.0 m in SUM20-10

  • 392 g/t silver equivalent* (3.04 g/t Au, 147 g/t Ag) over 3.0 m in SUM23-60

• Establishing Scale: Holes will test the extent and continuity of high-grade mineralization across at least 600 m eastward from Ruby.

• Fully Funded: The company is fully funded for this planned drill program having recently closed a $6.5M financing.

*Silver equivalent is calculated using US$20/oz Ag, US$1,800/oz Au with metallurgical recoveries of Ag - 90%, Au - 95%. AgEq = (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).

Galen McNamara, CEO, stated: "We have been looking forward to returning to drilling at the Hughes Project for some time. All the targets we are testing are highly prospective and represent some of the best in Nevada in our opinion. In addition, we already know there is significant mineralization at Ruby and in the immediate area which represents the eastern extension of the prolific Tonopah Mining District. We will now step out around known zones of mineralization and begin to define the footprints of these new zones."

The Drill Program

The program will consist of up to 7,000 m of combined reverse circulation and diamond drilling (RC pre-collars with diamond tails) at the high-grade Ruby discovery and east towards the Sapphire discovery (see the Company's press release dated November 7^th, 2024, Figure 1).

The Ruby discovery is centered on the Ruby vein system, located 1.3 km east of the Belmont Mine (Figure 1). The discovery hole, SUM20-10, intersected zones of strong, epithermal-related silver-gold mineralization (430 g/t silver equivalent* (2.47 g/t Au and 243 g/t Ag) over 2 m, see the Company's press release dated December 17, 2020). Follow-up exploration drilling, targeting proximal geophysical anomalies to the east, intersected similar styles of mineralization including 1,450 g/t silver equivalent* (8.41 g/t Au, 813 g/t Ag) over 3.0 m in SUM23-59 (see the Company's press release dated August 2, 2023) and 392 g/t silver equivalent* (3.04 g/t Au, 147 g/t Ag) over 3.0 m in SUM23-60 (see the Company's press release dated December 7, 2023). The intercept in SUM23-60, a 600 m eastern step out from the Ruby vein system, is within a 500 m interval of strong and locally pervasive hydrothermal alteration demonstrating the strong prospectivity to the east.

The program consists of a series of step-out holes from SUM23-59. Holes with pierce-points on approximately 85 m centres along the projected Ruby vein-system are designed to test for mineralization extension and continuity (Figure 2). Additional holes at Ruby will include a 250 m step-out between holes SUM23-59 and SUM23-60 (an untested strike-length of ~500 m) as well as a fence of holes through the projected Ruby vein system at a position to be guided by early results of the program (Figure 2).

ATM Program

In addition, the Company announces today a quarterly update with respect to its previously announced "at-the-market" equity program launched on October 4, 2024. During the quarterly period ended November 30, 2024, the Company issued a total of 501,500 Common Shares on the TSX Venture Exchange at an average price of $0.4184 per Common Share, providing gross proceeds of $212,924.85. Commissions representing 2.5% of the gross proceeds, being $5,323.12 were paid to Research Capital Corporation in relation to these distributions.

In addition, the Company advises that pursuant to the agency agreement among the Company, Research Capital Corporation, Eventus Capital Corp. and Eight Capital, out of the aggregated broker warrants of 988,813 as disclosed in its news release on November 1, 2024, the Company issued 41,300 broker warrants to Canaccord Genuity Corp. and Leede Financial Inc. in connection with the Offering.
