Perhaps I can give you just one example.
Inside the company that I work for, we do a lot of development work, so we would traditionally be contracted to run a pilot plant, for example, for a new copper mine. The difference is that we would be able to run that entire program for something less than $1 million. The challenge that we have in a rare earth organization, or in a rare earth property, is that we need to run that million-dollar campaign on an intermediate product, not on a primary feed source. So the company might spend anywhere between $5 million and $10 million to process enough material to generate the feed for that million-dollar development campaign. From my perspective, in terms of the actual test work, and then the follow-on work for both the separating and the refining, just a very crude estimate would be 10 times.
