Production Start...
In 2019, ZCCM Investments Holdings Plc (ZCCM) filed a petition in the High Court of Zambia to wind up KCM (‘the Petition’) on “just and equitable” grounds. Subsequently, ZCCM amended the Petition to include an additional ground based on allegations that KCM is unable to pay its debts. ZCCM also obtained an ex parte order from the High Court of Zambia appointing a Provisional Liquidator (‘PL’) of KCM pending the hearing of the Petition. As a result of the appointment of the PL following ZCCM’s ex parte application, the PL is the designated authority for exercising almost all the functions of the Board of Directors, to the exclusion of the Board.

March 23, 2022 - Mines and Minerals Development Minister Paul Kabuswe says the process of appointing a new Konkola Copper Mines provisional liquidator is underway.

Vedanta Resources has not published production numbers since 2019.

Deposit Type

  • Stratabound


Summary:

The Nampundwe pyrite deposit is situated on the western flank of a synformal basin composed of basement rocks, which are unconformably overlain by Katangan sediments. The deposit is hosted within limestones and schists of the Middle Katangan Cheta Formation, which roughly correlates with the upper portion of the Lower Roan Group. The Cheta Formation dips steeply to the northeast and is tightly folded with a northwest-southeast trending axial trace. The deposit comprises stratabound, massive-sulphide mineralisation located in a thick (50m to 130m) sequence of massive dolomites and limestones. No significant faulting has been identified either within the host zone or the individual orebodies.

The primary sulphide mineralisation at Nampundwe is pyrite with minor amounts of pyrrhotite, chalcopyrite and covellite.

Four orebodies occur over a strike length of about 1,600 m and dip from 70° to vertical along fold limbs and from 25° to 70° near the noses of folds. They thin at the fringes of the orebody and down-dip. The sulphide orebodies are overlain by oxide caps (gossans) that extend from surface to a depth of 60m. These deposits are generally parallel and range in thickness from 5-20 m. The oxide caps act as natural conduits for water thus making Nampundwe Mine relatively wet. The orebodies have been identified to a depth of 300 m below surface and remain open at depth.

The primary sulphide mineralisation at Nampundwe is pyrite with minor amou ........


Mining Methods

  • Sub-level stoping


Summary:

Mining operations currently exploit the steeply dipping ore bodies by conventional underground mining methods that are accessed via two vertical shafts, the No. 1 and the No. 2 shaft that provide access to a maximum depth of 300 metres below the surface. The mining method employed at the Nampundwe mine is conventional sub level open stoping with fan drilling.
