Always evaluate the cause of any Certified Reference Material (CRM) assay result outside of the certified three standard deviation grade range: Statistically, less than three in each 1,000 results should be outside this range, making this protocol a useful…
Don’t ignore moisture in reconciliation! Although much of Australia is dry we do have wet spells, and any mine in the tropics or in the northern hemisphere is going to have to cope with water to a greater or…

Employ a minimum of four Certified Reference Materials (CRM’s or Standards) at any one time: A typical protocol is to insert CRMs that allow assay accuracy to be monitored at grades equivalent to the anticipated (or known) break-even cut-off grade,…
Accounting for development volumes underground: Unless development is strictly on lines and the ore is either much wider or much narrower than the development face, the drives may meander and stripping cuts may need to be taken to straighten up…
