the lufwanyama emerald series, part twenty-two: beyond kagem
the kafubu schist belt does not end at the kagem licence boundary.
the geological formation that produces emeralds in lufwanyama district — the tri-junction of talc-magnetite schist, pegmatite, and biotite schist that creates the chemical conditions for chromium-bearing beryl crystallisation — extends across multiple licence areas. the same geology. the same ore-forming processes. the same potential.
grizzly mining limited operates within the kafubu belt. a zambian-owned mining company — one of the few significant zambian-owned operators in the emerald sector — producing emeralds from its licences for years. the fwaya-fwaya licence area has historically produced significant emerald material. kamakanga, chantete, miku — each sitting over the geological formation that the kagem data has characterised so thoroughly. each representing an extension of the same ore system that the chama pit has demonstrated at industrial scale.
what this means for the zambian emerald story:
the zambian emerald sector is not a single mine. it is a district. the kafubu schist belt is to zambian emeralds what the boyacá department is to colombian emeralds — a geological province with multiple productive areas, multiple operators, and a total production capacity that significantly exceeds what any single operation can demonstrate.
the named stones — insofu, inkalamu, chipembele, imboo, the kafubu cluster — all came from the kagem chama pit. but the geological logic that produced those stones operates across the full extent of the belt.
the depth question applies equally to every licence area. the chama pit currently mining at approximately 130 metres, with geological models suggesting the formation continues well below. the kafubu emerald system is not a shallow surface phenomenon. it is a deep-seated, structurally controlled mineralisation system extending in three dimensions — along strike across the belt, and at depth below every pit that has been opened within it.
the total emerald resource of the kafubu schist belt — kagem's documented production combined with grizzly and other licence holders, plus the unexplored depth potential and lateral extensions beyond current mining areas — is one of the most significant coloured gemstone resources in the world.
and most of it remains in the ground. 💚
