Todays Release........
Todays Release........Quetzal, thankyou friend for your input here regularly on how to do some of this calulating;
much appreciated.
Although I could not wrap my head around the conversion, I came to the conclusion that
until that information becomes clear and precise in the upcoming updated 101 that's being
prepared, it is sufficient enough to have the company make us aware that the previous 45
tons of gold indicated from the previous 1970's estimates, are now noted as significantly higher!
I think the MMs are betting on us little retailers to be blindsided by the fact that why we are
adamently focused on receiving the complete and updated 101, that they are banking on us
overlooking the significant statement being made today in the release ........
Gold is part of a 30 mineral suite being assayed as part of a 43-101 resource statement
being prepared, and is in addition to zinc, copper and silver already known to be
present in the deposit (see DFI press release of June 4, 2010).
The presence of elevated gold values and the possibility of locating high-grade
mineralization open at depth within the South West Basin just adds further potential
value to the deposit."
I personally have never been involved in a mining company that has 30 minerals being valued
in its NR-101.
For those who are new to this stock, you may wish to review this previous estimate to see what the previous estimate was that we are now exceeding in its value.........

| Preview | ABSTRACT
The Atlantis-II-Deep's metalliferous sediments were recently discovered along the mid-ocean ridge system extending into the Red Sea, at a mean water depth of 2,200 m. The average thickness is 7 to 11 m in different sub-basins. The metal-bearing mud contains sulfides of zinc, cupper and iron with significant amounts of silver, gold and cobalt. A variety of oxide, siliceous and carbonaceous gangue minerals are also present.
To determine the in-situ characteristics pertaining to the variability of the metal grades and mineralized thickness, and to study the natural phenomena, mining geostatistics was applied to estimate the Red Sea offshore mineral resources. Horizontal experimental variograms were computed along 0±180 degrees and then models were fitted to analyse the mineralization in each area. Kriging estimates indicate that 696.330 million tons of bulk sediments contain 1.891 million tons of zinc, 0.425 million tons of copper and 3.75 thousand tons of silver. Gold and cobalt contents were calculated from the analysis of solids in flotation concentrates as 47 tons and 5,368 tons respectively.
The significant outcome of implementing geostatistics to the Red Sea brine preciptates is not only for the evaluation of metal reserves, but it also provides a useful tool in the optimization of selective dredging of appropriate areas to be mined.
INTRODUCTION
The Atlantis-II-Deep is a unique marine deposit with a 2,200 m-thick sea water overburden. The stratified muds consist of varying quantities of very fine grained oxides, silicates and sulfides of zinc, copper and iron, and considerable concentrations of gold and cobalt. Extensive systematic exploration has revealed the fact that brine precipitates formed this potentially mineable orebody of economic interest.
The resource potential and economic worth of the Atlantis-II-Deep has been studied at different times utilizing data provided by exploration campaigns. The following are those worthy of mention.
In 1969, Bischoff and Manheim (1) assessed the in-situ value of the deposit at $2.5 billion, based on 41 analyses from 7 piston core samples that were collected during the Chain cruise. This represents: - 2.9 x10
