TORONTO, Oct. 22 /CNW/ - Amazon Mining Holding Plc (TSX-V symbol: "AMZ")
("Amazon" or the "Company") is pleased to report that it has materially
increased its title permit areas held at the Madeira Gold Project ("Madeira")
located in the Rondonia and Amazonas states of Brazil. The Company has
received encouraging field exploration results and has increased its
exploration concession to 332,011 hectares from 202,568 hectares (see figure 1
at http://files.newswire.ca/760/Amazon_Madeira.pdf).
Early stage exploratory ground field work has identified gold bearing
conglomerates in a farmland region located away from the Madeira River where
historic multi-million ounce gold production occurred between 1975 and 1995.
As part of the Company's Madeira work program, geologists targeted the
delineation of a medium grained conglomerate (known as "Mocururu"), in an area
located hundreds of metres away from the Madeira River. Samples taken from
water bore-holes confirmed the presence of the Mocururu and importantly that
the structure was gold bearing. In addition, gold mineralization was also
encountered in the coarse-grained sandy stratigraphic layers occurring above
and below the Mocururu. Historically, buried conglomerate structures exposed
by the Madeira River provided for reported gold production of over 1.6 million
ounces.
The water bore-holes, located 1,154 metres apart, were drilled to the
north of Humaita to approximate depths of 30 metre. Pan concentrates of
2 litres of material from every 1 metre interval of bore-hole interval were
prepared, and panning of this material produced fine grained gold over a 5 to
6 metre zone. The gold bearing zones begin at approximately 20 metres below
surface. The Mocururu in this area is 40cm thick. Gold was also recovered from
the coarse grained sand layers that occur above and below the Mocururu.
Amazon plans to continue to use well drilling equipment to cost
effectively determine the extent and nature of the mineralization at Madeira.
The method has been successful and can be utilized at up to one-tenth the cost
of conventional diamond core drilling. In subsequent work the Company expects
to be able to determine grade content for identified structures.
Mr. Cristiano Veloso, Amazon's President and CEO commented, "We are very
pleased with the initial results at Madeira. The program to date is
encouraging and will provide project exploration advances in a very cost
effective manner."
Background
To date, exploration on the property has consisted of the processing and
analyzing of remote sensing data to define shallow paleo-channels or
depressions that could be favourable for hosting gold deposition.
