For reference point, everyone should look at the Cascadura well drilled by Touchstone. Possibly 0.5TCF, company making, and valued at $250-$850m. Not yet in production, but added about $100m to mcap so far. That's a lot when you have an mcap of £7m as PRD does (14fold).
For the risks, see Aminex. 2TCF discovered, mired in bureaucracy developing it. Mcap down to less than £20m.
