TLU history ?

I' ve just discovered I'm the proud owner of just over 1500 TLU (now CRX) shares. While this doesn't seem like it will fund my early retirement, I don't have a clue how I would have obtained them, and the company web pages are now 'under construction'. If another holder could give me a very brief history lesson of the company that would be greatly appreciated, so I can get my 'books in order' if I ever sell out.

(My suspicion is that they were a spin-off from another explorer)
