The Valley Porphyry is the most recent discovery at TV Tower and the third porphyry system identified by our team. The discovery was made through systematic and rapid exploration from initial concept to discovery in six months. Comprehensive soil sampling defined a 1,400 metre by 400 metre, northwest-trending copper and gold-in-soil anomaly located to the south of the property's K2 high ...

2014-05-28· Porphyry copper deposits are generally composed of a "plug-like" igneous intrusion – a large magma body that is emplaced beneath a volcanic system. On average these deposits can have a vertical and horizontal extent of 1-2 km and can range from tens of millions to a billion+ tons in size. While copper is generally the dominant metal, porphyry copper deposits can contain multiple ...

Porphyry Cu systems are initiated by injection of oxidized magma saturated with S- and metal-rich, aqueous fluids from cupolas on the tops of the subjacent parental plutons. The sequence of alteration-mineralization events charted above is principally a consequence of progressive rock and fluid cooling, from >700° to <250°C, caused by solidification of the underlying parental plutons and ...

2018-03-14· The Biely Vrch deposit in the Western Carpathians is assigned to the shallow, sulfide-poor porphyry gold deposit type and has an exceptionally low Cu/Au ratio. According to 3-D geochemical models, there is a limited spatial correlation between Au and Cu due to the primary introduction of gold by a salt melt and Cu by low-density vapor. Despite a rough spatial correlation of gold grades with ...
