Tocvan Ventures – Bulk Sample Progress Update *Free Gold Identified*
CEO Brodie Sutherland provides a progress update on the metallurgical study and bulk sample work being done at the Pilar Project in Sonora, Mexico.
Highlights
• Precious Metal Diagnostic Leach Head Grade Results Return High-Grade
• Bulk Sampling and Metallurgical Plant Conditioning Ongoing
• Coarse Free Gold Identified in Screened Material
• Gravity Recovery Circuit Added to Process
1200 tonnes of material has been stockpiled so far, with first shipments of material completed. Metallurgical plant and laboratory setup is completed. Material crushing and screening is set to begin. Separate to the Bulk Sample, head-grade results from the precious metal diagnostic leach tests have returned high-grade results with the five samples averaging 6.2 g/t Au, 7.6 g/t Au, 1.3 g/t Au, 11.1 g/t Au and 7.6 g/t Au respectively. Diagnostic leach tests are ongoing and were collected from four trench areas and one select drill core duplicate. Preliminary results from the study suggest free gold is present in the samples and has been confirmed visually by testing sieved material. A gravity concentrator unit will be utilized to conduct formal testing on the presence and abundance of free gold in the finer grained fraction. At Pilar trenching related to the bulk sample has unearthed several buried underground working entrances along quartz vein structures, another indicator of the robust mineralized system and a useful tool for mapping new structures.
About the Bulk Sample
Up to 1,200 tonnes of oxide-gold material will be extracted from select areas exposed at surface across the project area, focusing on the Main Zone and 4-T Trends where preliminary column leach studies have returned promising head-grade and recovery results. Bulk Sample material will be extracted and prepared for processing by heap-leach method at a private mining operation less than 25 kilometers to the west of Pilar. Information from the sample will aim to provide a more detailed account of expected head-grade and recovery percentage of gold along with providing key information to optimize future production facilities. The information provided from the sample will be used for planning in coordination for permitting of full-scale mine and process facilities on-site at Pilar.
