Two things have me a little worried,
The pump is a potential thorn, as it is not an off the shelf, tried and true product. It is being developed for the project so long term reliability and costs are a potential unknown.

Up until now I was led to believe a single fracture horizon with multiple holes intersecting it were sufficient to get the flow rates required. However it appears multiple fracture zones, perhaps 3 or more one below the other will have to developed and the flow to pass through all of them more or less equally distributed. It may happen with luck, but if it doesn't, you either live with the problem of less than efficient heat transfer, or you some how try to correct it, not easy.

Bearing in mind that this project is still very much in the pioneering stage as opposed to a development along a known path, in my mind I've downgraded it from an exciting prospect to something that is still with risk.
Thus I've sold most of my share holding and decided to deploy the cash with better prospects for the time being.

I still have enormous respect for the management and have no criticism of their abilities or the way they are developing this project.

When a few things have been resolved further down the track, I'll look at investing again.
