During the mid-to-late 1970s some spectacular specimens were produced from a vuggy to cavernous fissure zone intersected by an exploration drift on the 17 level.
Pyrargyrite was a dominant mineral, occurring locally in vuggy masses, in the Cortland mine, Gunnison County.
During a nine-week period a vuggy zone about 250 feet inside the main haulage adit of the Mountain Monarch mine was exploited, and many fine rhodochrosite crystal groups were collected.
Rock with cavernous or vugular porosity occurs only in a few thin zones in the Floridan aquifer system, except in the Lower Floridan aquifer.
The product is effective when drilling formations that are fractured or vugular and when drilling highly porous formations.
