The emerald mines in the Kafubu pegmatite field all are located where metabasite and pegmatites come in contact (adapted from Sliwa and Nguluwe 1984 and Zwaan et al., 2005). The source of the specimen emeralds in quartz is the open pit of the merged Kagem Fwaya-Fwaya mine and
Pegmatites are also common in eastern Zambia where they have been exploited for aquamarine and tourmaline. Industrial Minerals A wide range of known industrial minerals in Zambia include feldspar, silica sand, talc, barite, phosphate (in carbonatite and syenite), limestone, clays (mostly ball clay and brick clay), graphite, and many varieties ...
veins and pegmatites, and the exact GPS positioning of documented points, have been recorded on digitalized to-pographic map sheets at 1 50,000 and 1 25,000 scale. Al-together 146 rock and mineral samples, and 39 samples for the determination of heavy minerals in rock samples were studied. The results of the analyses of these samples and
Zambias mineral industry is expected to become more stable in the coming years and recover from the global economic crisis that hit the country in late 2008 and early 2009. Further development of the countrys mineral resources is expected in the near future based on the current exploration of uranium, manganese, and nickel.
Aug 05, 2021 Following the incorporation of Luangwa Minerals Ltd as a 96% owned Zambian subsidiary, Tertiary Minerals plc has announced that Luangwa has entered into an option agreement with Mwashia Resources Ltd to acquire up to a 90% joint venture interest in five large exploration licences in Zambia considered prospective for copper.

The suite of pegmatite dykes and quartz-tourmaline veins that intrude the stratigraphic succession throughout the Kagem deposits occupy a range of trends, both concordant and discordant to the local stratigraphy.
The Kafubu area (Fig. 1) has sup- plied up to 20 per cent of the worlds emerald production, and is believed to be second in value only to Colombia. Though many of the good-quality stones are taken from the country illegally, the total annual production is estimated to be worth between 100 and 200 million USD.
