Hi Tonio,

The reason I didn't add it is that different grades of the alluvium will require very different ratios of the 'wet processed' ore produced.

For example:

400 tonnes Alluvium (grade of 0.03%) is required to produce one (1) Tonne of wet processed ore with grade of 12%.

While 160 tonnes Alluvium (grade of 0.05%) is required to produce one (1) Tonne of wet processed ore with grade of 8%.

For the former it is 45,000 tonnes, while for the latter it is closer to the 120,000 tonnes being 112,500 Tonnes.

With such a difference in volumes I have assumed the ROM is the amount of material required at the begining of each process.

Cheers,

Stoops.
