RE:Hypothetical Sunnyside/BRO Evaluation At $0.71, BRO's valuation is about $93 million. South32 is investing $5 Billion in development alone, right next door. Not to mention what they paid for the land. South32 has to think the mine from development returns is worth much more than their $5 Billion development investment. I will be under the assumption that BRO's value is at least on par to the investment amount South32 is committing to their side of the neighbourhood. Who would invest $5 Billion without appraising that the minerals in the ground far exceed the money they are putting in? BRO's minerals equal or exceed their neighbour, says the industry expert on the video noted below, with proof and evidence. Never would any right minded shareholder agree to sell BRO at $0.71.
