Project was suspended at February 2024, after that Restart at beginning of December 2024.

Deposit type

  • Metamorphic
  • Volcanic hosted

Summary:

The Matambo Project is named as two separate deposits which names are Center and West, within a 15 km-long.

The Matambo East deposit sits within a metamorphic suite of granite, described locally as meta-granite. The meta-granite has undergone multiple phases of metamorphism and has a range of alteration assemblages, namely silification with varying degrees of carbonate, chlorite, epidote, and plus/minus sulphide. The northern and southern extent of the granite is truncated by an Archean Greenstone belt that includes mafic volcanics, amphibolite, ultramafic, a range of schist plus/minus garnet-hornblende-biotite schists and minor intrusive dolerites.

The Matambo West deposit is largely the same geological setting as the Matambo East deposit with a package of meta-granite bounded by an Archean Greenstone belt that includes mafic volcanics, amphibolite, ultramafic, a range of schists plus/minus garnet-hornblende-biotite schists. There is a significant dolerite dyke intrusion within Matambo West that has displaced the meta-granite mineralization lodes. The dyke is void of gold mineralization and is more than likely a late-stage event.
