So no pressure then?
(Unfortunately it's not quite as clear cut, as I thought that the basins were interlinked. They are not.)
Just read that the 3 basins are not linked by tunnels or aquifers, so each is working independently. That means that the new plant will not benefit the Central Basin and we will need our pumps to continue without interruption. That may raise the question as to whether the existing pump is enough as demonstrated by the recent rise in level.
Other news I am looking forward to seeing is the results of the Centrifugal Concentrator's live trial test results. We know that the small scale test were impressive - "The Concentrator Testwork has indicated that the Mine Waste Dump material can be upgraded from an average gold grade of 0.7g/t to gold grades between 2.5g/t to 5.0g/t.", but they have not released any information on the full scale test. With the recovery rate at about 90% this would definitely help with our cashflow. Fingers crossed for that.
My concern however is that we are relying on the government to complete and finalise the studies, building work and commissioning the plants by 2020. South Africa is also in a drought right now, even though it is the rainy season. Not sure how things will stand if the drought ends and the plant is not operational.
Western Basin - not sure what the current treatment capacity is, but this is being upgraded to 50 mega litres per day.
Central Basin - supposedly treating 82 mega litres per day. The report we refer to from the Central Rand website regarding water levels are the results from this plant. (82 mlpd = 3,416 m³/h)
Eastern Basin - This plant is new and should be just about ready for business. It will treat around 110 mega litres per day.
The Eastern Basin has a new plant coming online, the Western Basin is getting an upgrade - but not sure about the Central Basin. We have proven for the past year that we can reduced the water levels, but we are back to where were started the year due to 'higher than normal rainfall'. Is this higher than normal for the rainy season? We also have no idea what was going on with the pumps as the data is not shown - were they even on during that period?
Still positive about the share though. If the government starts making money from the desalination then I imagine private companies will try to do the same. The Toll agreement and our own acquisition should provide us with a decent revenue - once the concentrator circuit is complete that could double or treble for the same amount of material.
There is also the chance that government policy or actions will change so if the Central Basin is not getting dewatered, this will probably be looked at again. At least we now know that CRND will not be selling any water or byproducts.
