sbl's interest in project

Hi everyone. Can someone point out what the deal is with SBLs interest in the project? I see mention of 70%, is the other party free carried the 30% of production (i.e get all 30% the revenue) or are they proportionately responsible for costs as well?

How about exploration and development costs?

I am just trying to do some forward projection work and this seems to have a fairly large impact on the amount of cash SBL will likely generate on a monthly basis. We are not talking massive wads of cash in ramp up either even at current prices.

Anyway appreciate any feedback/help and sorry if this info is buried in a preso or some report from 12 - 18 months ago.
