Wolframite Material Sourcing

Good specimens of wolframite are hard to find, and collectors count it as a highly desirable mineral. Tungsten ore is mined mostly in quartz veins and areas with granite intrusions, and is used for many everyday objects, thanks to its heaviness and ability to conduct heat. Wolframite is made up of iron, manganese, and tungsten oxide.

Wolframite - an overview ScienceDirect Topics

Most wolfram and much of the nonalluvial tin in the Slate belt are found in quartz veins, which are commonly less than a meter and rarely more than 2 m wide. These usually occur in sets of spaced parallel veins, commonly steeply dipping with individual veins separated by up to 40 m of host rock. Vein lengths rarely exceed 500 m.
