Geotechnical drilling.
Geotechnical drilling.The ban of a junior's existence.
They don't like doing any geotechnical drilling because it is necessary but tends to add zero value to the project.
For PGD they have now spun it into a value add proposition.
According to the tiny section in the resource report...they indicated they would use a stope angle of 50 degrees.
That is super conservative and with the small footprint...all effort should be made in making that angle much, much steeper. 65 degrees..if they can. Makes a huge difference in waste movement and in turn, IRR and NPV.
So, the winter program will be 2 fold.
Deepen CH-6 to add more value.
Geotech drill CH-6 and 7, so you can deepen the ultimate pit at a more profitable level.
PGD has been doing geotechnical drilling all along within the kimberlite pipe itself...so they know where the good and bad ground is...but they haven't drilled outside the pipe where the final pit walls will end up. You can see why it isn't done until it absolutely needs to be done.
LONG...PGD
