Descripción del sitio
Veins are N-S striking and sub-vertical. Some veins are discrete, continuous sheets which are traceable over 100’s of meters. More commonly, individual veins are narrow tension-gash shaped structures which form swarms or corridors. These are continuousover several hundred meters. Individual veins are 1m to 15m wide, but vein swarms may be up to 90m wide. Veining is crowded, with one vein or vein swarm every 50m or so. Veins sit within a 350m wide zone of faulting which is detected in drillhole sections
by changes in thicknesses of stratigraphic units, as well as intersections of fault breccia.
Veining is continuous through all the upper stratigraphic units, and from limited deeper drilling, appear to penetrate the LPS. Weathering is intense at shallow depths, and partial weathering with supergene mineralisation persists to depths of up to 300m below surface.
