Kagem Data

Kagem Information

  • Exploration 2015-10-07
    Exploration to date has focussed on and around known ore bodies and their extensions within the licence area. A substantial exploration programme using proven techniques is planned for the next few years to explore the rest of the Kagem licence area to further determine the remaining resource potential.
  • Processing 2015-08-13
    Exploration activities at Kagem are currently concentrated on the Fibolele and Libwente emerald belts, carried out in 2012, which consisted of 3,000 metres of core drilling, confirmed the down-dip extension of the TMS and pegmatites to a vertical depth of at least 200 metres from surface. Exploration in 2013 continued with a total of 10,534 metres of drill core recovered from 112 boreholes. The drilling results allowed a bulk sample pit in the Fibolele area to be defined. Bulk sampling commenced in September 2012 and as at 30 June 2013 the pit had been opened up along 170 metres of strike length. The delineated TMS body has been exposed together with associated quartz tourmaline veins, which are responsible for the emerald mineralisation. Three distinct mineralisation zones have been identified and developed to study the dynamics and yield of the ore.
  • Mining 2015-08-13
    The Kagem emerald mine is currently an open-pit operation, approximately 105 metres deep and 900 metres long. Overburden and waste material is mined in phases to expose the ore bodies for processing. Kagem is in the process of a high wall pushback programme, which is extending the pit, in its fourth phase, with a further 75 metres on the western side of the main Chama pit. This work is being carried out using both in-house capability and through a third party contractor. A 17 month programme has been agreed with the contractor, ending in September 2015. In-house waste removal will be carried out over 34 months, ending in February 2017. The pushback programme provides access to new areas of ore for future production and seeks to increase the overall rate of ore mining.
  • Geology 2015-08-13
    The rocks containing the Kafubu deposits consist predominantly of quartzites and quartz-mica schists of the Proterozoic Muva Supergroup which are sandwiched between granite gneisses of the Basement Complex and meta-sediments of the Katanga Super group which hosts the copper - cobalt deposits of the Zambian Copperbelt. Sub-concordant bodies of amphibolite and ultramafic rock (flows, sills or tuffs) also occur within the Muva schists. The ultramafics, which vary in thickness from 20 metres to 140 metres, have been altered by metamorphism and hydrothermal activity into talc-chlorite-tremolite magnetite schist (locally referred to as TMS) or talc-biotite schist (TBS). The amphibolites have also suffered varying degrees of alteration to biotite%u2013actinolite schists.
  • General 2015-05-10
    The Kagem Emerald Mine covers an area of approximately 43 sq km, located in the central part of NRERA, Zambia. There are six known Talc Magnatite Schists (TMS) belts with over 13 km of strike length within the licence area, the main current area of emerald extraction being the Fwaya Fwaya-Pirala belt, in which the TMS has a drill established strike length of 1720 meters. The primary production pit is FF-F10, located at the eastern end of the belt, which currently has a strike length of 920 meters. The mine has consistently produced some of the finest Zambian emeralds since 1984. Kagem has sold 11.4 million carats, 13.7 million carats and 14.9 million carats of emerald and beryl, generating revenues of US$ 6.4 million, US$ 9.5 million and US$ 12.6 million in 2005, 2006 and 2007 respectively. Some very large emeralds have been discovered at this mine. Gemfields is majority owned by the mining investment group, Pallinghurst Resources.
