Here is the info off Nuna's website, good read:

I think ZEN 2 years ago when they did their 5 ton bulk samples only drilled 85m depth, the basic use of this drill. Now, with the permit to 100 tons and this drill's capacity, this could get interesting. Still don't think ZEN would use this as a money maker but it is an option.
