So GL1's value increased approximately $23.5mil today. To get into more detail I'd need to know the estimated cost of exploration and technical studies, not to mention the risk of meeting milestones. So, in lieu of that (I don't have the experience to estimate) I would use the fact that this all reverts to 50/50 without those costs and milestones. So if the value of Manna right now is 50/50 and GL1 increased in value by $23.5mil I would estimate the value of BRB's portion is similar, i.e. closer to $23.5mil than $8mil.
All IMO, please DYOR and GLTAH.
