The orebodies are stratabound, and consist primarily of fissure veins
in the harder beds (limestone, sandstone and dolerite) and metasomatic replacements in the limestones.
The ores bearing the precious metals usually occur in fissure veins
, and the gangue consists principally of quartz, clay tale, and porphyry.
This ore occurs in boulders, stringers and lenses in a series of 14 nearly parallel fissure veins
in the rhyolite.
The Ccello Ccello Property consists of 2,700 hectares that includes a zone of vuggy-silica, advanced argillic alteration and fissure veins
, commonly associated with copper-gold porphyry systems, over an area of 3 km by 4 km.
The country rock is impure limestones and shales interspersed with extrusive trachyte bodies and trap dikes, accompanied by mineralized fissure veins
generally less than 18 inches thick.
The veins are quartz/calcite fissure veins
, mineralized by what appear to be multi-stage mineralizing events.
Fracture zones containing the mineralized fissure veins
and the more diffuse mineralization in their surrounding brecciated rhyolitic hostrocks, are localized along the western flank of an elongated dacitic dome.
The Properties include virtually the entire gold/quartz vein complex at Bad Vermilion Lake where over 100 deep-seated, sheeted fissure veins
have all recorded varying gold values.
Underlying remnants of extensive Roman surface workings, mineralization at Chala, is hosted within classic fissure-type, low-sulphidation, epithermal fissure veins
