If Newcrest's mine manager think its better to get coretrack rather than Kent Swick's (SWK) high performance airblast (RAB)rigs then it has to be good enough for me to take a small holding in this.
Most RAB rigs will only go to about 120 metres as well where as this should go down at least a km.
$2m in revenue for a couple of months work seems to indicate this has lots of potential and scaleable if they make a few more rigs.
