From this resource they will be looking to build a 100k oz pa plant to run 15 plus years running 2g/ton ore while looking for more gold , they should be able to build this at around 100m usd capex depending on how much extra infrastructure they need to put in, elec etc , the nearby randgold plant runs at a cash cost of 600 usd and they should be able to get close to this with a low strip ratio with a npat of around half the cash margin so should make 30mio usd a year from say 2020, if the Chinese can pony up 25m usd to get the ball rolling they will probably just about be able to make a strong case to build but it is drc risk and so an IRR north of 20% will be needed, my guess is they probably will just try to prove up things closer to 5m oz and sell out to randgold, but I dont think there is a lot of upside in the shares from here if that is the plan ...
