Summa Silver Corp. reported all 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: 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.

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) begin at 221.1 m in MOG22-12. This mineralized zone remains open in multiple directions with strong silver-gold assays returned from holes at both ends of the current drilling pattern. 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.

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: 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. 22.1 m at 368 g/t silver equivalent (2.88 g/t Au, 135 g/t Ag) beginning in hole MGR-14.

22.1 m at 320 g/t silver equivalent (1.19 g/t Au, 147 g/t Ag) beginningat 257.6 m and including 4.6 at 742 g/t silver equivalent (4.77 g/t Au, 372 g/t Ag) beginning on 275.1 m in hole MGR-8. widths are downhole core lengths, true widths have yet to be determined. AgEq is calculated using USD 20/oz Ag, USD 1,800/oz Au, with metallurgical recoveries of Ag 90% and Au 95%. AgEq = (Ag grade x Ag recovery) x (Au price /Ag price).

The focus of the recently completed multi-rig drill program at the Mogollon Project was on testing for un-mined extensions of the Consolidated Mine, centered on the north-trending Queen Vein. Holes MOG22-13, MOG23-14, 16, 18, 17 and 19 were drilled north of the Consolidated mine and holes MOG22-12 and MOG23-15 were drilled south of Consolidated mine. Results to date demonstrate strong grade continuity along the vein and within the complex vein system and outline two key areas, north and south of Consolidated, that require additional infill and step-out holes to better constrain plunge orientations and the lateral and vertical continuity of the high-grade mineralized zones.
