Well had a quick look at WLFunding. They have two off takes agreement (it appears) and need more money to get the ball rolling in England.
AZYellow is really after copper and gold with some possible by product of tungsten.
It appears Tungsten is in the top 20 list for European minerals.
"A critical raw material cannot usually be replaced by another material. The most critical raw materials to the EU are antimony, beryllium, cobalt, fluorspar, gallium, germanium, graphite, indium, magnesium, niobium, platinum group metals, rare earths, tantalum and tungsten. European countries are almost entirely dependent on the import of these materials." Source:http://www.geofoorumi.fi/20103/page4.html

In the end it is all up to market and demand sentiment.
