Mining at Geita is by both open pit and underground methods. The open pit mining is currently undertaken by conventional truck-and- shovel open pit mining method on one active pit (Nyankanga). The open pit mining is conducted using Geita owned, operated and maintained fleet. A contractor provides drilling and blasting services.
The Gratz vein was mined in both world wars and produced sphalerite, galena, calcite, and barite. The concrete foundation for the mill and a calcite and barite tailings pond still remained on the property in 1990. Several shafts were opened on the vein, and some of them are still open. Most of the adits have caved in and are not accessible.
Calcite - Calcite - Origin and occurrence: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth’s calcite is of magmatic (i.e., igneous) origin; it is the chief constituent of the rare rock called carbonatite.
- A small area near Antire Road in St Louis County produced these specimens in the 1960’s. Quartz geodes were completely filled with calcite. These had to be put in a weak acid solution to remove the calcite, and sometimes honessite after millerite was in the geode. This is an exceptionally large spray. Most of the sprays were about 1 cm in length.
