Hydrothermal Mineralisation and Geothermal Energy 16 of 25

A normal requirement for many open pit mines is dewatering to remove water inflow as the mine depth extends downward below the water table. Various wells would be located around the open pit perimeter to remove water and to preclude inflows from adjacent areas. Pressure and thermal monitoring boreholes would […]

Hydrothermal Mineralisation and Geothermal Energy 14 of 25

One of the ways minerals are extracted from epithermal and porphyry deposits is by the use of open pit mines.  These mines are significant challenges to progress from exploration to operational mining.  Exploration would identify the prospect. Detailed exploration would identify showing (surface indication of mineralisation that requires further investigation […]

Geologists would visually inspect and log the core to create a record of rock types (lithology) and their sequence (stratigraphy).  Elemental and mineral composition could be determined using techniques like X-ray fluorescence analysis.  The degree of alteration would be examined to help predict rock permeability for geothermal fluid circulation.  Core […]
