If you are doing a lot of drilling with resource targeting at least some wedges should be planned for and I stress the word planned. Something more basic is diamond drilling from surface using a raft of drilling management tools and remedies that basically I am not going to mention here but are well-used with many working in that part of the world. Negotiate a cheap rate for your top 200m. PEX should have navi on hand if needed here. It makes so much sense if some drill holes look like being duds from deviation. The cost over the loss is a no brainer.
