From the SDL release

"Current undeveloped DSO projects in Australia are valued at anything up to A$10/tonne of in-ground DSO resource. Our current market capitalisation is equivalent to around A$2.50/tonne based on our current DSO Inferred Resource
base of 190 million tonnes of high quality DSO material. This ignores any prospect to increase this DSO tonnage as drilling extends to new exploration targets ..."

If BRM was worth $2.50/tonne for its undeveloped resource it would be worth more than $1 billion.
