Stockwork

 

an ore body formed by a mass of rock permeated by a dense network of variously oriented veins and vein-lets containing the ore minerals; such minerals in the form of phenocrysts are usually found in rocks interpenetrated by veinlets.

A distinction is made between areal and linear stockworks. Areal stockworks are cube-shaped with sinuous boundaries. Linear stockworks extend in one direction. The dimensions of stock-works range from a few dozen meters to several kilometers. Stockworks are classified with the group of hydrothermal formations that arise upon the deposition of the metal-bearing substance from hot mineralized solutions circulating in fissured rock. Some deposits of copper, molybdenum, tungsten, gold, tin, beryllium, uranium, mercury, and other metal ores belong to this group.

In the Stockwork Zone, two holes were drilled on a NE orientation at minus 45 degrees also targeting intersections at 40-60 m depth.
During this most recent campaign, B veinlets varying between 1mm to 3mm have been widely observed in the Porphyry as well as major stockworks. The widespread presence of B veins, including some cross-cutting D veins, stockworks and numerous Mo showings indicate that we are on top of the Porphyry system and getting closer to the core of mineralization.
In these particles, the proportion of each phase is fixed (60% of dark phase and 40% of bright phase) and the internal structure varies from single to branching veins (simple to stockwork intergrowth, cases 1 to 5) and from single to multiple inclusions randomly distributed (coated intergrowth to emulsion-like intergrowth, cases 6 to 10).
