Looking for opinions on a comparative company to get an idea on a fair mc for hvy once we are producing.
Is it RDG? Is it as simple as that?
They are nearby, grades are comparable, if RH comes through we will have a similarly sized resource.....
Whilst RDG does have some other revenue streams my understanding is that they are a relatively small percentage when compared to its Garnett operation.
Could we argue that on the assumption that our resource and grade will be the same (discounted against HVY as I believe we will be bigger and better) and throw in a 10% discount based on RDG's other revenue that we should fairly be valued at 90% of RDG (approx 180M mc today) once we are producing?
I appreciate this is a very simplistic approach to a mc and that supply/demand, world events, technology etc will change over the next 3-5 years however I don't see why it is not a likely scenario.
Would love to hear of other comparable companies and thoughts on my opinion.
