The mining operations take place against a backdrop of complex and disturbed geological area with high methane emission rates and major and minor faults and dykes. The faulting range between 1,0m to 30m up and downthrow. The mine also records high methane emission rates. The normal gradient stands at 6 – 8 degrees and varies to a maximum of 14 – 16 degrees. Thus, an intense prospect drilling programming is undertaken from a 100m grid to as close as 30m apart.
