A coiple of days ago GMD released a discussion on their purchase of the ex FML resource at Laverton. They paid $250 million for a resource of approx 4 million ozs, which is less than our market cap for a lot less ozs. We need some more spectacular drill results to sustain the share price.

Also in the discussion paper were two items of interest that re-inforce what I have said about milling and ore types.
On page 16 they stated that deeper fresh rock drilling was almost non existent as the Barnicot mill was amenable to oxide and trasitional material only. The crushing and grinding circuits would have been designed for that ore and as the mill is small (1.5mtpa) the cost of upgrade was prohibitive. GMD will truck it to the new bigger mill at Jupiter.
On page 17 they talk about the Lancefield deposit being comprised of different two milling classes. Main lode is Refractory and West lode is non refractory. These require different processing techniques with the refractory ore being the problematic one. Historically this was done through roasting (KCGM had a plant 20 kms NE of Kalgoorlie at Gidgee to do this) Sulphur dioxide was released to the atmosphere along with other stuff which is not easily permitted in todays world. Alternative processing is by either bug plants (sulphur eating microbes) like the old Harbour lights plant, HPO (high pressure oxidation) or a super fine grind using Isa mills, which is what KCGM went with. All of these add extra cost to the processing.

It will be interesting to see what the metallurgical results for Lakeview come back as.
