Spoke to a geo...they said the brecciated volcanics is a good sign in that will means higher grades are more likely. Found this in wikipedia to explain it better....
Hydrothermal breccias usually form at shallow crustal levels (<1 km) between 150 to 350oC, when seismic activity (an earthquake) causes a void to open along a fault deep underground. The void draws in hot water and as pressure in the cavity drops, the water violently boils - akin to an underground geyser. In addition, the sudden opening of a cavity causes rock at sides of the fault to destabilise and implode inwards, the broken rock gets caught up in a churning mixture of rock, steam and boiling water. Rock fragments hit each other and sides of the fault, and attrition quickly rounds angular breccia fragments. Volatile gasses are lost to the steam phase as boiling continues, in particular CO2. As a result, the chemistry of the fluids change and ore minerals rapidly precipitate. Epithermal deposits are mined for copper, silver and gold.
Also heard a couple of other Co's taking more than a passing interest...could be a interesting month or two.
