Have you factored into your calculation that the mine will most probably be selling a 50 to 60% tin concentrate which will need to be refined elsewhere. Refining tin is energy hungry not to mention may require more tonnage than we can provide for a refinery onsite to be viable.
Look the company has not yet released any details on the recovery of tin so anything we do now is pure speculation.
My more conservative calculation yielded an estimate of $US30 per tonne reduction in processing costs.
I hope that SS V1.2 gives us some more detail on this matter.
