At Vanmater's, the metalliferous clay marl is overlaid by a grayish sedimentary limestone.
The occurrence of this metal in the copper-bearing and other metalliferous rocks of this region, may be confidently affirmed.
In the same manner, from other mixtures of vitriolic and metalliferous material are made vitriol and metal.
Granite, porphyry, and limestone are found here, as in the other metalliferous regions.
In comparison, the metalliferous deposits are the merest incidents in the development of this great group of mineral resources.
On each side it has handles, which are held in the hands by whoever washes the metalliferous material.
They agitate the metalliferous material with wooden scrubbers and wash it in a similar way.
There was scarcely a mineral beneath the loamy soil which masked the metalliferous rock which they did not work.
The metalliferous limestone is covered to a certain thickness with a marly schist, and other more recent rocks.
Doubtless the plan is feasible, but the Indians are at present the sole owners and occupants of the metalliferous region.
