Wiluna ASIC ?

For anyone interested in numbers.
In the June qty the plant processed transitional and fresh ore from Matilda with a recovered grade of 1.13 g/t (1.44 x .7876 )
* ASIC $1509
In the march qty the plant processed oxide ore from Matilda with a recovered grade of 1.34 g/t ( 1.51 x .894 )
* ASIC $1092
The Wilunga resource
* Transitional ore 1.53 g/t forcast 84.3% recovery yields 1.14 g/t (c.f, 1.13 march qty )
* Oxide ore 1.26 g/t forcast 90.8% recovery yields 1.28 g/t ( c.f. 1.34 june qty)

The average grade at Wilunga (1.43 g/t) is slightly higher than Matilda (1.39 g/t )
We are aware of the split between oxide and transitional at Wilunga which yields an average recovery of 1.225 g/t based on the forcast recovery percentages.

I can't find a split between oxide and transitional at Matilda but the average recovered grade may not be too different based on the above numbers.

In addition to better grades at Wiluna OP, the proximity to the plant is a real cost saver compared to Matilda. What will also be interesting is the stripping ratio. 1:1 (or less) is fantastic, 3:1 is pretty good & 7:1 can work if ore grade, haulage & mill throughput are good enough. Hopefully the stripping ratio at Wiluna OP will be consistently better than Matilda.

it's all good on paper. One thing to be wary of is the met recoveries of the transition zone - it will be variable, I am hoping these Muppets have done enough test work to get a handle on it.

If they screw this up, then any last semblance of market confidence will evaporate - you'll be looking at either receivership or 2c IMO.
