Hi Meteor,

We do need to careful that we are comparing apples to apples.
I believe the figures from the April update were based on actual metals.
The figures from the May update are about concentrates.

From the May update and my calcs below:
Copper concentrate production is exceeding forecast with an average grade of 24.2% copper @ 76.4% recovery, producing 1,047 dmt of concentrate.

0.242 * 0.764 * 1047 = 193 tonnes of metal copper

Lead concentrate production is exceeding forecast with an average grade of 67.19% lead @ 79.3% recovery, producing 1,440 dmt of concentrate.

0.6719 * 0.793 * 1440 = 767 tonnes of metal lead.

Zinc concentrate production is exceeding forecast with an average grade of 46.62% zinc @ 87.5% recovery, producing 4,589 dmt of concentrate.

0.4662 * 0.875 * 4589 = 1871 tonnes of metal zinc.


The question is, were the April figures DMT or WMT?

Hopefully all these updates will become standardised so comparisons can be made. I also wait for the production guidelines and settlement date.

Btw, I could be wrong with my interpretation so DYOR.
