Mr. Frederick;
As one of the diminishing number of Naxos thread posters I still will
respond to I have something for you and other non-morons to consider.
I respect the right, however, of all morons who wish to post on this
thread and I reserve, as well, the right to ignore them at my pleasure.
Now to the exciting new world of clay resource gold recovery. If anyone
wonders why we hired John Norton and Jeremy Ison then wonder no longer.
Wander around a little in the world of Carbon-In-Pulp recovery technology.
"Since the first CIP operation was commissioned in 1980, no further
conventional plants have been built in South Africa for recovering
gold from newly-mined ore or from residues. There could be no better
demonstration of the fact that CIP has been accepted by industry as
being superior to the former technology. In fact, CIP has become the
preferred method for gold recovery world- wide, for several reasons.
"The majority of gold-mining activities throughout the world are
concerned with lower-grade near-surface ores. The low costs of CIP,
and the short start-up periods, make such operations an attractive
proposition, even when the gold price is depressed. These ores
often contain clay or shaley materials, which do not filter well
and increase the soluble losses from filtration plants, but which do
not materially affect a CIP operation. In 1995, there were 42 primary
carbon-adsorption plants (i.e. not counting operations on tailings
from conventional plants) in South Africa, with an annual capacity of
over 91 million tons per annum. The largest plants in the world, in
terms of tonnages treated, have been designed, constructed, and
operated on the Witwatersrand to recover the last vestiges of gold
from the dumps remaining from earlier activities. Without CIP, it
is doubtful that such huge re-treatment operations would be viable-yet
carbon-adsorption technology is equally suited for gold recovery on
the small and medium scale."

Let's get back to serious discussion about the issues of current and
future events.
