There are at least 37 different types of mica with a world wide distribution and hundreds of different mining sites.
Production figures from 2010 show the most important sources to be Russia (100,000 metric tones), Finland (68,000 t), United States (53,000 t), South Korea (50,000 t), France (20,000 t) and Canada (15,000 t).
Mica has been mined in North
Carolina since the mid 1800s.
Mica shist is normally found in precambrian rocks
The most commonly found minerals in micaceous schist soil are quartz and mica, but mostly the latter.

Garnet schist-- as well as mica schist--can be found anywhere where clay rock with some calcite content-- such as siltstone or a mudstone, for example-- can be compressed (via metamorphism) and consequently sqeezed into rock-like layers.

i thought they were made of copper and zincand it's are pennies made out of mica schist not is
Mica schist is primarily composed of mica, whereas aventurine - note the spelling- is composed of quartz with abundant inclusions of mica. This makes for a relatively hard, tough and attractive material that can be polished into jewelry and many other items.
