yes lime stabilization is a relatively quick and overall cheap process that can be used to create a very good running surface.
I've seen some terrible ground looking like a runway after running 3-6% lime through it; Bitumen stabilization also excellent and both are often used on maintained haul roads and both are good at keeping water out; yes with good initial supply 2-5km are possible production ranges per day; so yep technically you could run from Manono to Moba in just a few months, but i dont think they could get 5mtpa/750kt out through that route too easy Why? because that alignment runs through an area which looks like it would possibly get knocked out for about 3-4 months during the wet season...but yes they could lime it and open it up.
, it may actually have gotten them around the reporting hurdle hey. Could run that route for 6-8 months of the year possibly whilst also running south also. Anyway, for the time being i think they need to run south tbh, the road alignment will be in and running by end of year, i just see it as the way to go at least in the short - medium term until they ramp it right up and the infrastructure that seems to be jigsawing around Manono comes together.
"In your view, that $200+ but under $250 leg, is economical for the project and reasonable enough to get started whilst scale of economies is homed in on?"
yes if you can get FOB for sub 250 i think we are in a good place; be great if it was at that $160 figure of course, but reduce that 200+ figure with credits and i think the $160 will be a target once other routes open up. $160 is a very very good figure for where Manono is; IMO i think that $160 figure was a bit fanciful when you look over those route; sits down and start to gather information regard what the rail companies are charging per tonne etc etc.
Tin credits are great, who knows , we could even get under $200 per tonne, but i wouldn't be banking on that at this stage
