Where sampling by shovelling is unavoidable, in crements shall be taken from evenly as possible over the surface of the ore to be sampled, ensuring that each Increment contains all sizes of ore represented In that portion of the ore. The recommended shovel dimensions are given in table D1
The procedure for sampling using a shovel shall be as follows.
a) Dig a hole to a depth of at least 300 mm in the ore bed, ensuring that the ore dug out of the hole is thrown clear of the hole The angle of the sides of the hole should be selected to prevent the ore rolling down the sides of the hole and causing further bias in the sample,
b) Take an increment of the appropriate mass from the bottom of the hole in eilher sinQle or multiple operations of the shovel, as appropriate.
