Hullo
I am doing some research on Dan Walker's claim/s and want to get hold of him ASAP. My email is migdakota@yahoo.com.au - does Dan still own the claim that was for sale on Trade Me and what became of the dredge?

Hi
I see there are two claims 53215 and 53459. I am interested to see any geology reports on the likely yield if dredging is done at 30 m and interested in knowing what the sediment is like. The suction dredge failed unfortunately.
I believe the claim was for sale?
I am currently working on a larger feasibility study.
Cheers
Chris

Hi thanks for that - I am interested in the turbidity issue - how does dredging increase water flow?

hi - I just researched turbidity - water quality - it is easily remediated even for a large bucket dredge -

G'day thedr, Well ... if you have discovered the means to reduce turbidity from a bucket dredge so the regulators would allow a bucket dredge to operate in an active New Zealand waterway, then ... you have discovered the holy grail of dredging! Up until the late 1980s there were numerous digger and screen gold recovery plants working in active waterways in New Zealand. Then it was decided that the turbidity created by using heavy earth moving equpment in an active waterway was unacceptable. The usual suspects (leftie academics) then did their bulky reports to "prove" turbidity was environmentally damaging. Policians armed with thick reports were then able to effortlessly stop all mining that used heavy earth moving equipment in active waterways. If the turbidity regulations were not so stringent there would have been a digger and screen operation in the Clutha river, on Dannys claim, well before now. There is no doubt that there is payable gold in the lower Clutha, but to get it, using efficient means, would increase turbidity levels well above what is currently allowed. The Grey river dredge owners were charged just a few years back after operating the dredge too close to the active river bed when they were unable to contain the turbidity. A digger and screen operation in the Shotover river during the early 1990s. Regards, Rob (RKC)
