RE: Drill Time Calculation based on KenGif InformaScuderia430
I would say your calculations are pretty close to reality. The only thing I would do is factor in 12 to 15% for "down time" due to holidays, equipment issues, etc. To do 25, 000 meters of drilling is going to take a lot of rigs to get finished before the end of 2010.
