What happened to all the zinc?22 Mar 2019 08:29
This is from yesterday's RNS:
"The Project targets an initial processing rate of 20 tonnes per hour producing a zinc concentrate and vanadium pentoxide before ramping up to a targeted 40 tonnes per hour producing zinc metal, vanadium pentoxide and a lead concentrate. The Project targets to produce annually over 8 000 tonnes of zinc, 1 500 tonnes of vanadium and 15 000 tonnes of lead as it ramps up to full capacity over a 2-year period."
However, in the webcast last year, Leon Coetzer gave estimated figures of 26,400 tonnes per annum of zinc, 15,400 of lead, and 2,040 of vanadium (based on a 40tph plant).
Is the final extraction process really that inefficient? Or what?
