Excellent Metallurgical Results At The Hughes Silver-Gold Project
VANCOUVER - Summa Silver Corp. reported silver and gold recovery results from initial scoping-level metallurgical test work from its Hughes Project, near Tonopah, Nevada. Results demonstrate strong recoveries of silver and gold from the Murray and Belmont areas. Outstanding Silver and Gold Recoveries: Representative composite vein samples from the Murray and the Belmont areas returned recoveries ranging from 83.7% to 96.7% for silver and 95.9% to 97.1% for gold from flotation concentrates. High-Grade Concentrate Produced: Both composite samples produced high-grade concentrates with grades of 6,954 g/t silver and 58.5 g/t gold from Belmont plus 1,486 g/t silver and 12.6 g/t gold from Murray. Conventional Milling Expected: The demonstrated recoveries were produced from a sample grind size of 80% of particles passing 75 microns or smaller which is typical in conventional milling processes. Importance of Gravity Separation: The test work also showed that prior to flotation, gravity separation improved recoveries for silver and gold significantly at both Murray and Belmont. Drilling at the Ruby Discovery Continues: A 650 m step-out from the recent new vein discovery at Ruby is in progress testing a large and undrilled geophysical anomaly.
Galen McNamara, CEO, said, "This work represents the first modern metallurgical testing done on our Hughes project in Tonopah, Nevada. As expected, the results confirm the potential for very strong precious metal recoveries. The extremely high concentrate grades from the historic Belmont mine area are of particular interest. With our recent discoveries on the project at Ruby and Sapphire, we are well positioned to continue to unlock value in and around this storied mining district. Additionally, we are preparing a fall drill program at Mogollon to test new targets and more information will be shared when planning is complete."
