how much would it cost to develop peelwood?

Now that we're well and truly on the right track to getting Peelwood off the ground, I'm now thinking about the costs that will be incurred to get the next stage going.

Is anyone in the know of how much the Exploration/Development cost will be up to production time?

I see Sultan have around $900K cash on hand at the end of Dec and they've been spending at the rate of about $900K per 6 months. They also have US$3.25mill at their disposal at a rate of $150K/month.
