There's a massive amount of variability in drill speeds but I found this which could be accurate. Does anyone else have knowledge on this topic?
NQ drill size is most common and produces a 60 mm core sample
"A normal drill speed for NQ drilling is around 5-10 meters per hour without stop. The drill speed depends on numerous factors, for example rock type, homogeneous rock, wear of the drill bit, flow of water, depth of drilling, terrain and more. An example of drilling in one 24-hour period: 7,5 meters x 24 hours = 187,5 meter/day. To drill 2500 meters you will need the following numbers of days before finishing: 2500 meters/187,5 meters = 13,5 days with no stops for maintenance."
this puts 8 rigs without breakdown at 1500 meters per day. This equates to 20 days best case for 30,000meters. At 5 meters per day for 20 hours a day that puts us at 38 days. Maybe they are on 12 hour days, then 62 days for 8 rigs at 5 meters per rig per day.
I could be out to lunch on this and would love any insight from anyone more knowledgeable on the topic. Cheers all. I know I'm excited for the summers NR's.
