MDDK
Introduction
Mpokoto is located about 700km west of Lubumbashi in the Katanga Province. The area was originally targeted based on the presence of an extensive gold geochemical anomaly in termite mounds.
Follow-up augur and diamond drilling has indicated the presence of stacked, gold mineralized zones in a clastic sequence in the Mpokoto target area.
2021 site trip showed little artisanal activity on site and remaining drillcore in good condition.
Geology and Mineralisation:
- The Mpokoto area is a metavolcano-sedimentary succession referred to as the Lukoshi formation with metamorphism to amphibolite grade.
- The gold mineralisation is hosted within sheared interlayered conglomeratic sandstones. It occurs as northwest to southeast striking and moderately south and southwest dipping sheared intervals between clastic meta-sedimentary rocks in the hanging wall and metaigneous rocks in the footwall.
- The deposit contains oxide, transitional and primary sulphide ore types with oxide ores from surface to approximately 30 to 40 metres below surface.
- Principle ore minerals: Native gold inclusions in arsenopyrite, pyrrhotite (+pyrite) – gold is very fine grained.
- Related to regional E-W-trending faults – key structural control – interpreted to be related to a dilatational jog. Mineralisation is bedded.
- The gold mineralisation is hosted within sheared interlayered conglomeratic sandstones.
- Mineralogical investigations carried out showed a distinct paragenetic association of native gold inclusions in arsenopyrite.
- Sample grades inside the assay file show Au ranges from 0.00-16.40 g/t with mean of 0.40 g/t Au.
