Drilling At The High-Grade Silver-Gold Mogollon Project

VANCOUVER - Summa Silver Corp. reported on the remaining assay results from the recently completed drill program and an update from on-going data compilation at the high-grade silver-gold Mogollon Project near Silver City, New Mexico. Key Current Drilling Highlights: 1) 23.2 m at 433 g/t silver equivalent (3.66 g/t Au, 134 g/t Ag) including 1.2 m at 2,686 g/t silver equivalent (26.3 g/t Au, 484 g/t Ag) both beginning at 240.5 m in MOG23-16. 2) 15.5 m at 250 g/t silver equivalent (2.29 g/t Au, 60 g/t Ag) beginning at 186.6 m and 10.3 m at 234 g/t silver equivalent (2.12 g/t Au, 59 g/t Ag) beginning at 221.1 m in MOG22-12. 3) This mineralized zone remains open in multiple directions with strong silver-gold assays returned from holes at both ends of the current drilling pattern. 4) Work is just beginning at the Mogollon project with this first target representing only 1% of the total vein and structure strike length present at the project.

Historic Drill Results Validated by the Company's Modern Drilling Campaign - Based on the success of the drill campaign, the Company now expects to be able to use historic drill hole data from the Consolidated Mine area for resource estimation purposes, particularly for domain volume definition and with appropriate risk mitigation applied in estimation and to the resource classification. Highlights include: 1) 14.0 m at 579 g/t silver equivalent (4.46 g/t Au, 219 g/t Ag) beginning at 299 m in hole MGR-38. 2) 22.1 m at 368 g/t silver equivalent (2.88 g/t Au, 135 g/t Ag) beginning at 290.6 m and including 4.0 m at 776 g/t silver equivalent (5.69 g/t Au, 322 g/t Ag) beginning at 297.3 m in hole MGR-14. 3) 22.1 m at 320 g/t silver equivalent (2.19 g/t Au, 147 g/t Ag) beginning at 257.6 m and including 4.6 at 742 g/t silver equivalent (4.77 g/t Au, 372 g/t Ag) beginning at 275.1 m in hole MGR-8.

Galen McNamara, CEO, said, ”These drill results continue to demonstrate that significant mineralization remains around the old mines of Mogollon. Our exploration drilling has also successfully verified the validity of historic high-grade drilling completed by a past operator in the 1980's. We are currently prioritizing targets for our fall drilling activities and plan to share more information both on new targets, and further historic data in the future. In the meantime, preparations are well underway for our upcoming drill program at the Hughes project in Tonopah, Nevada scheduled to begin in May."
