hardman seeks 1.3 bln barrels oil, page-19

I kept this info which was posted about the Mauritanean Govt right to buy into Ching, which was posed by someone a couple of months ago, if I recall it came from some Citicorp research in Febuary... basically there's a 150% reimbuirsement for pro-rata costs if the Govt buys. I doubt they could afford it but they may opt for a small percentage they can and/or seek international development funding for some of it.

"The Mauritanian Government has the option of participating in PSC A up to a maximum of 16% from the date on which the exclusive authorisation is granted.
From the date of participation the Government must bear its percentage share of future costs and must re-imburse the Contractor for 150% of those pro-rata past
costs which have not by then been recovered...."

"Joint Venture Area B - Deep water Blocks 4&5 (PSC B)
(This Area includes Chinguetti and Tiof). As for PSC A except..." ...basically, the same deal as far as Mauritanean Govt buying into the fields goes.
