The best undeveloped niobium deposit in the world - I don't think so

I received an email from Argonaut saying the CXX is " a likely takeover target " with the "best undeveloped niobium project in the world"

From the CXX annual report Panda resource is 20.6Mt at 0.68% Nb2O5; and located in Tanzania, Africa. The Duncan depsoit at Mt Weld, in Australia, has an (indicated and inferred) undeveloped niobium resource of 37.7 Mt at 1.07 Nb2O5.

Not sure why Argonaut would say the words they did. Maybe some one can explain why Panda is so much better than Duncan.
