I do understand the difference between different drill types, but I'm not experienced enough with nickel explorers to know what to expect next, just anticipating an announcement to say they've at least not drilled dusters... maybe?
For example, you can use UV light when you RC drill for lithium to get some visuals from pieces of rocks like the attached image or usually they say pegs have been intersected etc.
Maybe you or others can tell us if nickel explorers can use ways to get an idea of what they've drilled?? (eg like how lithium explorers use UV).
