Sorry all i just couldn't help myself here...condog how long do you think its going to take TON to process this 4.5 million tonnes of tailings with this 200K processing plant you speak of, also how many people are going to be needed to run this operation? and for how long?
This is a stock I don't hold but is on the watchlist (actually, researching this reminds me of MGX a few years ago in terms of development stage).
Condog, in terms of the $500net per ounce figure you have mentioned, is this an industry standard figure you've used for open pit/tailings processing or have I missed a quoted figure buried in an announcement somewhere?

Personally i don't see how this project could not be viable but i guess that will all be released in the scoping study due soon.
The scoping study will reveal all...its just i know of another Goldie with a similar sized tailings deposit who are spending about 20 mill on development using a specialised mill to finely ground the ore so that as much gold as possible can be recovered.
MAIDEN MINERAL RESOURCE ESTIMATE FOR WINDARRA TAILS DAM
● Initial Mineral Resource of 4.50 million tonnes at 0.78 g/t gold for 113,300 contained ounces Indicated Resource for the Windarra Tails Dam Project
● Resource estimate confirms historical records from internal WMC reports
● Metallurgical studies are underway on bulk samples derived from the drill samples
● Scoping Study is on-track for completion in February 2010
Cheers condog - I guess the scoping study may provide further information, especially condiering the other equipment they will need to process the ore and what sort of credit facility they will be looking at to set it all up (if required).Its a baseline estimate figure i use as with todays gold price most producers are able to achieve that.....in this case they should bne able to easily beat that by a safe margin...

So bottom line: I am hoping on the basis of technical reading of the operational philosophy unless the management stuffs it up and gold price crashes, TON is going to be very encouraging even with .78 ppm ore value.
We need to consider the expensive operations of mining and crushing will not be there.
Windarra tailings is therefore very promising. The amount of gold is however not much.

I have a limited understanding of tailings, but i was under the impression that any gold in a tailings deposits would be very small particles (micro) contained within slightly larger and yet still very small particles...so fine crushing would still be required to release the gold....is this not true miner?
Are tailings just ultra small particles similar to powder and the gold simply needs to be separated?

So Cynical
Tailing is the fine material comes out from the ball mill. So the size will always be lesser than after crushed product and after milled product. They never need to be crushed again.
IMO they can be directly fed into mill again then the crushed product can be treated with the additon of cyanide to make the slurry once again to go through the brine solution.
Not to make it technically difficult sounding, the crusher is no no with the tailng product.
Hey Miner,
Not sure if your correct about the crushing
check out envirogolds website
http://www.envirogold.com/
Theyr'e looking at using "albion process technology" which requires ultra fine grinding b4 leaching
As I understand it so-cynical has it right ... the gold is locked up in the tailings otherwise it would have being recovered in the initial processing

Haven't bought into Ton yet but hope 2 b4 announcements are out
So your saying the tailings would be just put through a ball mill again, or thought the leaching thing again or both? and if we are looking at just 0.7 grams per tonne maybe only half of that could be recovered through normal processing? because you can never achieve total recovery....that's why the gold is in the tailings in the first place.
Also with the shipping container comment i made...i just wanted to give people a visual aid in understanding the mathematics and reality of recovering 1 ounce of gold (approx) from 30 tonnes of tailings....never wanted to give the impression that shipping it anywhere was viable or on the cards.
EVG is the other tailings mob i was talking about.
Interesting debate....
Albion Technology sounds good but expensive, obviously a hell of a lot cheaper though then digging gold out of the ground....I would have though slurry and cyanide....but lets ask them...
Dont ever lose sight this is not a project that will get or aim to get 100% recovery.... they will have to use drilling data, sample data of some sort to pick thier targets..... I recall???? 29% of the dam has been identified with reasoanbale quantities.... (too tired to find it)...
Any way I will email or call them and ask them what sort of process they expect to use , or what they have short listed, I will also aske them waht sort of % they envisage might be commercially recoverable....
Its likely to early , and the scoping study in Feb will reveal all, but theres no harm in asking....
I have edited this post and just sent them 7 questions.... they will be posted here if I recieve a response...
