native copper page 9 of jorc report, page-42

Found my own answer on pg 13 of the resource statement.

1612 drill holes occur within EPM 13049 consisting of 222,146.5m of RC drilling (1430 holes) and 46,872.4m of diamond drilling (175 holes). 7 holes have no drill type recorded.

82 % of drilled meters are from RC and 18% from DD

Some clarification/comparison on how RC drilling vs. DD (due to different methods and ore structure, clays etc.) may be inadvertently missing NCu in one, but picking it up in the other is going to be important imo.
