RE: Operational Update17 Sep 2013 12:01
Having read yesterday's RNS now several times I clearly view the update in a more positive light than some investors who have decided to bail out today. Bad management in the past has probably set production back a year and added to the debt but the current CEO seems far more on the ball. The appointment of Adam Mooney in my view will be a game changer, providing, as he openly states, cash flow can be managed and capital investment made to remove bottlenecks in the production process. Investment in new stacking equipment capable of stacking to in excess of 8 metres would appear, from the RNS, to be the most urgent issue. I am no expert in extraction metallurgy but for me the big positives from the RNS were: -
(1) the issues with low permeability appear to have been largely sorted
(2) the utilisation of secondary sulphide containing ore to manage clay content presumably means that the total recoverable copper from the mine using the SX/EW plant has increased
(3) control of the permeability issues has enabled pad 3 to be stacked to 4.2 metres with the possibility of increasing to 6 metres with modification to existing equipment. I believe the stack height is now the most crucial factor in achieving winter production. Laboratory tests have suggested that high agglomerate permeability can be maintained under loads equivalent to >10 metres stack height and it would appear that Adam's goal is for 8 metres. By more than tripling the original pad volume the benefits during the winter months would be enormous, as the heat capacity of the pad is tripled but the surface area for heat loss remains almost the same as for a 2.5 metre pad. The higher the temperatures within the pad the faster the chemical reactions, which are exothermic and generate more heat. A 4.2 metre pad may not allow production throughout the entire winter, but as stated will allow them to operate further into the winter period and restart operations earlier. Maybe they can increase that to 6 metres before the winter.
(4) as the pad height increases the capex and Opex decreases proportionately with respect to tonnes of ore stacked. It's obvious that for an 8 metre high pad you've only got to excavate the pad once, line it once, etc. which then frees up equipment for other activities - sorry if i'm stating the obvious.
It seems to me that thanks to Adam Mooney, the main technical issues are resolved or close to being resolved. There will always be room for further improvement. It's whether the company can get through this difficult financial period and make the necessary capital investment to upgrade equipment like the radial stacker. Surely with such progress on the technical front the $20 million loan, alluded to in a previous RNS should be forthcoming.
Good luck to all invested here. With an average of around 3p I'm in for the long haul now.
