VANCOUVER, Nov. 1, 2011 /CNW/ - Diamond Fields International Ltd.
(DFI:TSX) (DFI or the Company) is pleased to announce an update to the
independent NI 43-101 compliant Technical Report on its Atlantis II
deposit, to include manganese. The updated resource statement by ACA
Howe International Limited estimates the deposit to contain
approximately 80.9 million tonnes of sediment grading 2.69% manganese
(tonnes and grade on a Dry Salt-Free basis) at the Inferred resource
level, for a total of 2.18 million tonnes of manganese.
The Company is currently examining the feasibility of recovering
manganese by froth flotation as an additional metal credit to the base
and precious metals contained within the deposit (26th July 2011 press
The Atlantis II basin containing the Atlantis II deposit is located in
the Red Sea, approximately 115 kilometres west of the city of Jeddah.
The Atlantis basin comprises four interlinked sub-basins which lie at
depths of approximately 2,000 metres below sea level. Deep-tow seismic
data from earlier exploration indicates that sediments in some parts of
the Atlantis basin may reach in excess of 30 metres. On average only
the top 8.5 metres of the deposits have been sampled by coring to date.
The composition of the deeper sediments below 8.5 metres is currently
unknown, but offers potential to host a further significant addition to
the overall resource. On the basis of the data from core samples taken
to date, the Company estimates that less than one quarter of the
sediments by volume contained within the Atlantis II Deep have been
The updated NI43-101 resource estimate undertaken by ACA Howe will be
published on SEDAR within the next 45 days.
