This week’s 30 Seconds of Info – Grabbing samples from ore passes

This week’s 30 Seconds of Info comes from Ian Glacken – Director of Geology.

Grabbing samples from ore passes:  Deriving grades from underground ore passes, especially in precious metal mines, is a hit-and-miss activity at best, and may give a woefully biased sample at worst.  However, if you must sample ore passes (and it’s not recommended), lots of small samples (5-10 kg) taken over a few days, rather than one larger (20-30 kg) sample per shift.

If you would like to contact Ian, his email is iglacken@snowdenoptiro.com
