At Juanicipio, the Valdecañas vein system underpins value.
This Valdecañas vein system is not a single vein, but a system of related veins. The principal vein is depicted to the left, having the Bonanza Zone shown in red and the Deep Zone shown in blue.
The resource numbers outlined below comprise the data on which MAG’s PEA is built, and with much of the Inferred resource already having been converted to Indicated, we are currently in the process of updating our technical report.
The surface projection of the Valdecanas vein system has a distinctive surface alteration thumbprint we can apply to exploring the balance of the property going forward.
