    • Stockwork (Geol) A metalliferous deposit characterized by the impregnation of the mass of rock with many small veins or nests irregularly grouped. This kind of deposit is especially common with tin ore. Such deposits are worked in floors or stories.
    • Stockwork (Mining) A system of working in ore, etc., when it lies not in strata or veins, but in solid masses, so as to be worked in chambers or stories.

Century Dictionary and Cyclopedia
    • n stockwork In mining, that kind of ore-deposit in which the ore is pretty generally or uniformly distributed through a large mass of rock, so that the excavations are not limited to a certain narrow zone, as they are in the case of an ordinary fissure-vein. This mode of occurrence is almost exclusively limited to, and very characteristic of, stanniferous deposits, and the word is used especially in describing those of the Erzgebirge. Also called stockwerk (the German name).
