Silicified tuffaceous volcanic rocks from a newly discovered one km wide zone of hydrothermal alteration discovered at the ATV project. Note the heavily silicified fractures extending from the foreground into the distance. Such silicification may be an indication of precious metal-bearing veining at depth.
