Reality Check: First Solar and Tellurium

If you find a significant source of Te that is better than a few hundred 100 ppm, please let us know. I do not invest in faith of the invisible. All sources I have seen do not indicate there is any other substantial source, at any price. Gold is the only metal of the USGS's 9 rarest metals group (that includes Te) that is mined in the 2,000 tonnes/yr range you're hoping for. Gold costs 120 times more and has had centuries of research and investment. The least expensive of the others is palladium, 50 times more than Te and has 1/2 the Te production.
