500 ppm Mo translates to 0.05% which is probably ore grade these days in an open pit type mine. WO3 (tungsten) assays need to be twice this or 1000 ppm for ore. Or 5000-10000 ppm for underground mining. None of UNO's assays come any where close to the minimum required for an open pit. I don't think they understand the economics of these metals. They're better of playing around at Chester where they have the grades, although low on tonnage.
