Inspection Schedule

Open all containers, note any different markings on form or indications of heterogeneity.

Sampling Schedule

If there are no indications of material heterogeneity then sample on an incremental basis of 1 MT sub lots. If heterogeneity is suspected select the incremental groups accordingly but in sub lots of 1 MT or less.
Select 10% of the ingots schematically, drill each ingot using a predetermined template which accounts for the whole of the ingot form. If no drilling facility is available solid pieces may be taken from different positions on the ingot form using a cold chisel.
Where heterogeneity or contamination is suspected it may be considered necessary to segregate certain drums and prepare samples separately. 

Sample Preparation

The drillings from each incremental sub lot should be mixed, drillings or pieces subdivided if necessary, to produce a homogeneous bulk sample in each instance.
Two options are then open:
1. Quality samples can be drawn from each homogenised sub lot bulk sample for analysis.
2. Alternatively a composite can be prepared from portions of each of the sublots to give a total parcel bulk sample from which total parcel quality samples may be drawn.
The balance of the sub lots being held for reference purposes.
