Coretrack says the GT 3000 has been achieving hard rock penetration rates of more than 30 metres an hour, many times faster than the existing platform-based drill rigs. It has used just a three-man crew and consumed only 14.6 litres of diesel per hour, compared to as much as 600 litres per hour used in competing oil and gas rigs.

The Salamander 1 well drilled by Panax Geothermal in South Australia in 2010 reached a depth of 4025 metres after 42 days and at a cost of $15 million. That equates to an average drill rate of 95 metres a day at a cost of $3,750 per metre. It says the GT3000 could have done the same job in half the time and half the cost.

My position remains hold, though tempted to sell most to reduce my debts, if not see some progress with timetables and prices..
