SUM20-10 469 2.0m inc. 1,437 0.5m Looking to the northeast Ruby Discovery Area *AgEq is calculated using US$20/oz Ag, US$1,800/oz Au, with metallurgical recoveries of Ag - 90% and Au- 95%. AgEq = (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)). True thicknesses are estimated to be 70-80% of drilled intercept length. Silver and gold grades comprising AgEq are listed on page titled "Hughes Property Drilling" in this presentation 1.4 km inverted 3D chargeability and resistivity model Chargeability - High Chargeability - High Undrilled Targets Summa Silver Corp. | TSXV:SSVR | OTCQX:SSVRF Frankfurt: 48X Resistivity - High LEGEND SUM21-XX 450 11.6m Drill Hole intercepts > 100 g/t AgEq g/t AgEq* Intercept Length Page 22
