Unless contracted at the time of negotiation, other elements 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.

Material should be degassed / burnished and not black.

Form

Broken cathodes.

Packaging

Drums with uniform net weights per lot, usually 250 KG each.

Lot Size & Tolerance

1 MT (+/- 2%)

Documentation

Standard documentation, as per MMTA Consolidated Regulations.

Weighing & Sampling

As per MMTA Consolidated Regulations.

Other Notes

1. CMBA material is produced by CTT, a division of Managem.

2. Original producer packing can be of particular importance; close attention should be paid to the MMTA regulations relating to the resealing of damaged drums, or repacking of drums no longer suitable for onward transit by the holding warehouse.

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 5 MT sub-lots. Tip 10% of the opened drums and using the appropriate shovel take samples top middle and bottom, place in a clean drum/container.  

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 samples from each incremental sub-lot should be mixed by coning and quartering to produce a homogeneous bulk sample in each instance. These bulk samples should be crushed or milled to give a final quality sample.

Two options are then open:
     1. Quality samples can be drawn from each homogenised sub-lot bulk sample.
     2. Alternatively a composite can be prepared from portions of each sub-lot to give a total parcel bulk sample from which total parcel quality samples may be drawn.

The balance of the bulk samples being held for reference purposes.
