Summa Silver Corp. announced the discovery of additional high-grade silver and gold mineralization in the first two holes of the year at the Hughes Property near Tonopah, Nevada. The 2021 drill program was initially designed to test the lateral and vertical extent of structurally controlled, epithermal-related, high-grade silver and gold mineralization discovered during the 2020 drill program. Based on an updated synthesis of all 2020 drill data, multiple priority drill targets were defined. One of the first targets tested in 2021 was the Rescue vein system, part of the Belmont Mine target area. Six holes were drilled at Rescue in 2020 and intersected numerous intervals of high-grade mineralization over a strike length of 360 metres. Hole SUM21-30 tested the up-dip continuity of mineralization near SUM21-20 (6,220 g/t AgEQ over 0.7 metres within 3,182 g/t AgEq over 1.4 metres and hit the highest grade intersection to date on the property; 11,992 g/t AgEq over 0.9 m within 4,408 g/t AgEq over 2.8 m from 430.6 m. This interval demonstrates the significant high-grade potential of this target within the Rescue vein system and together with results from 2020, represents a priority area for further drilling. Hole SUM21-032 was a 50 metre step-out along the vein from hole SUM20-06 and intersected a broad alteration zone that returned 155 g/t AgEq over 15.1 metres including 525 g/t AgEq over 1.2 metres from 397.4 m. Defining the strike-extent of this broad zone of continuous silver mineralization, with local high-grade intervals (e.g., SUM20-06; 596 g/t AgEq over 18.5 metres including 3,760 g/t AgEq over 2.5 metres is considered a priority for future drilling. In both holes the high-grade intercepts comprised silver-sulfosalt bearing, banded to brecciated quartz ± adularia veins with associated argillic alteration halos. The south-west striking, structurally-controlled veins are hosted in intermediate to felsic volcanic and volcaniclastic rocks of the Mizpah Formation. Assays are pending from three additional holes drilled into the Rescue vein system, with more holes currently being planned. All samples were sent to Paragon Geochemical Laboratories in Sparks, Nevada for preparation and analysis. Paragon meets all requirements of the International Accreditation Service AC89 and demonstrates compliance with ISO/IEC Standard 17025:2017 for analytical procedures. Samples were analyzed for gold via fire assay with an AA finish ("Au-AA30") and silver via atomic emission spectroscopy after four-acid digestion ("AgMA-AAS"). Samples that assayed over 5 ppm Au were re- run via fire assay with a gravimetric finish ("Au-GR30"). Samples that assayed over 200 ppm Ag were re-run via fire assay for Ag with a gravimetric finish ("Ag-GRAA30"). In addition to Paragon quality assurance /quality control ("QA/QC") protocols, Summa Silver implements an internal QA/QC program that includes the insertion of sample blanks, duplicates and certified reference materials at systematic and random points in the sample stream.
