Gem minining with minumum environmental damage

Greetings!

I really enjoyed Mr. Wise’s article on mining in Brazil , which can
be viewed at www.rwwise.com.

As you may know, Pakistan has abundant gem mineral deposits,
including emeralds, tourmaline and peridot, but exploiting those
resources with the MINIMUM of environmental damage is an issue facing
us.

I have heard that new techniques in gem mining are being used in
Africa. If any of you can enlighten me with your knowledge on the
subject, or point me towards someone who can, I will be very
grateful.
