....on page 6, you see a cross section of the mineralisation. On the other side of the fault is the footwall sediments and volcanics, a totally different type of rock to where the mineralisation is located.
Mineralisation is in the Dolomitic Siltstone package for the py3, while the Pyritic Siltstone package has the lower grade py1 deposit.

The real question as they drill and increase the resource size will be whether to mine both types of mineralisation, and shandy them in the process plant, or go for a smaller process plant and just mine the higher grade py3 zone.

Another alternative will be to go out up to 100m from the FRF, which would effectively increase the overall resource but lower the average grade, but allow for open pit mining.

I'm just having difficulty in believing they would have an open pit that was 10km long and down to 300m deep. The strip ratio is going to be massive, probably making it not worthwhile. Then there is another option of open pit py1 and underground py3 together.

Basically lots of options are appearing to open up for the company.
