You don't PLAN to drill lengths measured to the nearest 10cm, that would be the actual depth. Regarding why we would stop in mineralisation, we've already encountered drilling problems (which happen all the time due to various reasons) in this phase one exploration seeing one hole end in spod that was confirmed to be the beginning of a 100m+ interval on follow up. I wouldn't ponder over it to much but the deeper the hole it usually means they like what they are seeing along the whole way down.
