I don’t think anyone is expecting a drill bit to match 30-40% rock chip grades. As you said with lithium… they get 4-5% rock grades then hopefully trickles down to 1-2% drill grades.

look at WA1 grades. Drill bit getting anywhere from 1-4% some a little higher. Most ppl who have read a few articles would know that 1-2% lithium drills is very appealing and any company who has these 1-2% grades in the masses in commercially viable.

Now when it comes to Niobium idk what the drill bit % must be to look decent enough to mine? Is it similar to lithium at 1-2% or needs to be a bit more. Atleast if for nothing else we can work with WA1 and their average grades?
