Tocvan Ventures Corp. (CSE:TOC) said a diagnostic leach study at its Pilar Project in Mexico has yielded strong results, showing that gold is recoverable at 95% to 99% and silver at 73% to 97%.
"These results far surpass our expectations and provide us with new insight on the optimization of gold and silver recovery at Pilar,” Brodie Sutherland, CEO, said in a statement.
Additionally, the company said head screen assays reported high grades for both gold and silver at 2.7 to 24.9 grams per ton (g/t) and 8.8 to 74.2 g/t respectively, while gravity concentrate assays for gold and silver ranged from 35.6 to 290.3 g/t and 53 to 1,152 g/t respectively.

The company noted that most of the gold and silver can be recovered with gravity concentration and agitated cyanide leach.
"To have such a large percentage of the gold and silver free and accessible for multiple recovery methods allows us to evaluate the most efficient ways to develop the project. This is a huge checkmark for the project and an excellent indicator to the industry that Pilar can be developed. We look forward to further evaluating the bulk sample data in the coming months,” Sutherland said further.
The bulk sample consisted of over 1,400 tonnes of oxide-gold material extracted across the project area, focusing on the Main Zone and 4-T Trends which had produced encouraging preliminary results.
The Pilar Gold-Silver property in Sonora has produced some of the best drill results in the region.
Tocvan is looking to take advantage of the prolonged downturn in the junior mining exploration sector and is earning 100% into the Pilar Gold-Silver project and the El Picacho Gold-Silver project, both in Sonora, Mexico.
