Get PriceIn this case, with potential mining widths in mind you may want or need to sample potential rock between zones. If you sample a 30m wide zone, then have 5m of barren, then another 30m zone – it would be best to sample right through. If you two 1m zones separated by 30m, probably not important to sample everything in between.
