Other Notes
All other elements should be each 0.10% max, with the exception of Fe. Unless contracted at the time of negotiation, other elements above do not give Buyer right to reject and may only form the basis for further discussion in the event material assays outside of these maximum levels.
This grade is sometimes also called ‘Western’.

Inspection Schedule
Open all containers, inspect entire contents, making note of any different markings, forms or indications of heterogeneity or contamination. Segregate if necessary. Confirm packing lists, and note all details.
Sampling Schedule
If there are no indications of material heterogeneity then sample on an incremental basis of 10 MT sub-lots. If heterogeneity is suspected select the incremental groups accordingly but in sub-lots of 10 MT or less. Sampling from all the drums for a 10 MT parcel, for larger parcels sampling from all the drums may be impracticable, consequently increase the number of drums by 20% of the 10 MT drum lot number.
The drums should be individually tipped, samples drawn with the appropriate shovel to form the appropriate sub sample to each lot, mix and reduce in size, to < 2.5mm sizing. Mix and draw bulk samples of 10 KG for preparation.
If heterogeneity is suspected then sample incremental groups accordingly but in sub-lots of 5 MT or less. It may be considered necessary to segregate certain drums and prepare samples separately.
Sample Preparation
The bulk samples can be then crushed, individually or they can be composited, to 1 mm. The samples can then be rolls crushed, mixed, milled, and a quality sample produced. The balance of any subsamples should be kept.
