Summa Silver Corp. announced that it has sampled multiple new high-grade silver-gold-copper zones on public lands at the Mogollon Project near Silver City, New Mexico (the "Mogollon Project"). Key Highlights: There are significant extensions to high-grade veins and rock sampling shows that mineralization is widespread in new areas not previously prospected in modern time.

Highlights from surface sampling of new high-grade zones include: 8,475 g/t silver equivalent; (8,373 g/t Ag, 5.39 g/t Au and 4.43% Cu) and 6,956 g/t silver equivalent (471 g/t Ag, 71.1 g/t Au and 4.,21% Cu) from the new Silver Bar Vein system. 3,652 g/t silver equivalent (221 g/t Ag, 39.3 g/t Au and 0.83% Cu) and 1,382 g/t silver equivalent (431 g/t Ag, 0.14 g/t Au and 9.09% Cu) from the northern extension of the Queen Vein system. 3,046 g/t silver equivalent (812 g/t Ag, 3.80 g/t Au and 18.4% Cu) and 1,847 g/t silver equivalent (302 g/t Ag, 18.2 g/t Au and 0".

High-grade copper mineralization has also been identified with grades of up to 18.4% Cu returned. The Mogollon Project continues to host significant additional discovery potential and it now features more than 75 km of cumulative vein and structure length of which only 0.5 km has been drill tested by the company. Preparation is underway for a fall drill program on the project with further details to be shared once planning is complete.

Drilling continues at the Hughes Project, Nevada where it has intersected meter-scale quartz veins, breccias and stockworks featuring visible silver-sulfide minerals at the Ruby and Sapphire targets.
