Merlin Diamonds, page-82

What we know:
- The mine has been successful in the past
- More recent digs/drills/whatever were not very successful
- They hired two mining big wigs about 6 months ago
- They are hiring workers
- They bought the XRT machine and have installed it successfully
- The machine is running and calibration is due to be finished mid-February (i.e. now)
- They plan to do many works on the site (see quarterly report)

Diamonds have been found in the past year and past quarter (we don't know if it was using the XRT or not). But as for making money and selling diamonds, we don't have much information (any?). Best to follow the old adage here: and only invest what you can afford to lose.
