The programme will comprise about 1,000 metres of diamond core drilling to depths of up to 80 metres, with average depth likely to be around 60 metres.
Drilling will initially target areas that are open-ended east-north-east and south-east of the known mineralised zone.
Drilling will also target several nearby high-gravity geophysics anomalies. An independent review of Star Zinc's historical geophysics data showed a good correlation of gravity anomalies with the mineralisation intersected in the initial programme.
Drilling is expected to be completed during October, and Galileo plans to provide regular updates on core appearance, portable XrF spectrometry indications and actual laboratory assays.
"The initial programme confirmed the presence of very high-grade willemite (up to 38% Zn) adjacent to the collapsed (pit) area in the mineralised zone with extensions to the east and west of this area,” said chief executive Colin Bird.
“We believe that this programme should extend the known ore zone to the east and potentially identify near-surface mineralisation in areas highlighted by the geophysics review. The overall assessment showed further the presence of heightened lead values in the deposit. This is recognised, academically, as a marker for the potential of a nearby feeder source for mineralisation. The company, depending on results, may test this theory for the presence of a deeper feeder source during this programme.”
Star Zinc has the potential to be a stand-alone project or a supplier of run-of-mine ore for the nearby Kabwe project.
