Golden Cross Resources (GCR.ASX) is a stock which I have taken a great deal of interest in over the years. The reason is simple enough - the company has been a prolific 'project generator' insofar as it is able to generate projects and get others to fund. That appears to have stopped after Dr David Timms left the company, but nevertheless his legacy remains.
The positive for this company was that it has a potentially large target in the Central-West of NSW. The problem with this large target is the grades. We can expect more tonnes from this project. In fact I expect a lot of more tonnes from:
1. Extensions of the Buckley's Proposed Pit
2. Possibly from nearby satellite deposits around Larras Lee, which has had only a few drill holes put into it some years ago...with pretty decent results.
My concern is that a lot of investment might be going on hope. They have already outlined a 150Mt resource containing 1.5Moz of gold (grade 0.3%Au) and 0.5Mt (grading 0.3%Cu) of copper. The project has great infrastructure. The problem I have is the low grade. You also have to conclude that similar grade material at Larras Lee (assuming so) would not be viable given the extra trucking distance.
What this project needs is a new method of mining. I have a few ideas, but I have no idea as to their commercial viability. These types of deposits were formed by the micro-fractioning of the rocks millions of years ago, and subsequent ingress of mineralised fluids. It would be nice to think that these rocks can be leached the same way. i.e. You drill the region with heaps of holes, allow fluids to enter these holes to react with the host minerals, which were formed at far higher temperatures and pressures, so might be unstable under present conditions. The problem is achieving 'micro-fracturing'. The problem is the confining pressure. The drill hole provides some access, but hard to see micro-access being achieved...which brings us to the contemporary solution: Drilling holes at 25m spacing, developing tunnels into the ore, blasting the ore, crushing it, grinding then extracting the minerals.
Anyway, why can't I dream as well.
