As an example of in-situ values relating to posts here recently, here are some data for ML (on Toronto) which is a copper producer with expansion plans for more copper and Moly
At $1.40 copper and $10 Moly, ML has projected in-situ resources of US $6.8 billion (it is the feasibility study stage for expansion but is already producing 11m lbs copper annually in a fully permitted and functioning mine)
Its market cap is US 40m, i.e. less than 1% of market cap.
