Slightly higher ore tonnage treated combined with slightly lower...

Slightly higher ore tonnage treated combined with slightly lower average grade resulted in slightly lower total concentrate production.

Simplified example to illustrate this point:

old case: 100t @ 1.2% = 20t @ 6%
new case: 110t @ 1% = 18.33t @ 6%
(new case had more ore treated, but the grade was lower enough to result in an overall drop in concentrate produced)


No need for big concern - just mining maths
