Digging question

[guitarxexe]

Hey folks! Just started playing again and have tons of questions (which I'll leave for another topic), but for now I have a quick question about prospecting, which was the first thing I did as soon as I logged in!

Anyway, there's this little annoyance when you try to prospect, and it says that the deposit is less than 1m away, but you just can't find it no matter how much you wiggle around there. Now, I remember one time I asked about this before, I was told a very handy trick, but I can't remember it exactly. I think the trick was to put up your tracking for that material, find the deposit, but not stop there but instead keep going further 100m and try prospecting there.

I don't remember it exactly, but I think it was something like that, and it used to work perfectly for me. Does anyone know what I am talking about? Could you refresh my memory?
