I was thinking particularly of a sale price for a resource, a buyer of that resource could conceivably pay 5% of the JORC resource for the costs and risks and time factor associated with mining, processing and shipping of the product. So I agree, if the buyer spent say $80m in capex, plus the costs of adding value in mining, processing and shipping (I can't quantify that), plus 30% ROI would need to add up to at least $288m. Of course there would be upside and downside risks in the product price over time amongst other things. There would be an added benefit of a likelihood of nearby resources (a bird in the bush . .)
