I drill last year 50km north of this region and we drill over 100m every day. We made a 30km road for the drill... in two weeks!!!

I don't prevaricate. Diamond drilling has much improved in the last 15 years with the improvement in the quality of bits and industrial diamonds. If you were an old standard driller from the 50's and 60's you would not even recognize the business. Everyone drills with unitized rigs, at least BQX wireline and with bits that will last 2000 feet and more. The figures I quoted were from a greenstone with Diamet bits and with hydraulic drills with Boyles heads. You may be used to reading complete lies from the likes of Black Swan about 4 drills running or incompetent stories from Gitennes etc.. 20 metres a day etc.. but unless you are in completely brecciated sedimentary rock in some mountainside with a rinky dink patch together mexican drill, 50 metres is what you should get per 12 hour shift, not per day. A lot of foreign operators are working with foreign drill crews and substandard equipment and experience.. If they used Canadian crews and rigs their production would be better. We used to do 75% of all the underground diamond drilling worldwide and a good percentage of the surface stuff too. RC drilling itself is a Canadian invention.

If you are drilling in a mountain sediment you had better get drillers who have drilled in BC. That stuff is admittedly much slower.

My best 12 hour shift was 480 feet in greenstone which is like cheese to drill I will admit. But there was 120 feet of porphyry in that too.
