Carbon steel resources producer and developer, Aquila
Resources Limited (ASX:AQA Aquila or the Company) is pleased to announce
further promising manganese assay results from its Avontuur Projects located
75km north west of Kuruman, in the Northern Cape Province of South Africa.
The above assay results are from significant
intercepts in the next nine holes drilled within the 74% owned Avontuur
Projects, which comprise a permit area of 370sq km. The manganese discoveries
were identified on two mineralised prospects some 20km apart and
adjoining the northern-most farms of the main Kalahari Manganese Field (Figure
1).
Southern Project
Drilling on the southern project area of the Avontuur
permit has discovered manganese mineralisation in the Hotazel Formation, which
is interpreted to represent an extension of the Kalahari Manganese Field. The
permit boundary is approximately eight km north of the Wessels underground
mining operations, where ore is mined over a depth range of 300 to 500m.
A programme of diamond drilling is in progress across
the projected trend of the mineralisation. Following the results of the
drilling announced on April 4th 2008, assays have been received from
EBEX 6, 7 and 9. EBEX 8 is yet to be completed. Details of the analytical results
of intercepts from these holes are contained in the following tables.

Northern Project
Drilling
on the northern project area of the Avontuur permit is also testing manganese
mineralisation in the Hotazel Formation along the northern end of the Avontuur
Basin. The Avontuur
Basin is approximately 10km long and is
located 20km north of the larger Kalahari
Manganese Basin.
Following the promising assay results from GHEX 2 announced on April 8th
2008, further encouraging assays have been received from six diamond holes
drilled along a 2km projected mineralised trend. The northern project is at an
early stage of exploration assessment and further drilling is ongoing. Details
of the analytical results of intercepts from these more recent drillholes are
outlined in the following tables.

The
Kalahari Manganese Field represents over 50% of the world's total known
land-based manganese resources. The field was opened up following the discovery
of the Hotazel deposits in 1961 and the subsequent establishment of rail
access. The rail head is at Blackrock, only 9km to the south of the Avontuur
permit boundary. Currently, mining operations are conducted at Mamatwan and
Wessels by Samancor and at Gloria and N'Chwaning by Assmang.
The
manganese deposits occur as three laterally continuous sedimentary beds
interbedded with Superior-type banded iron formation within the Hotazel
Formation, a stratigraphic unit of the early Paleoproterozoic Postmasburg Group.
The
lowermost of the three manganese units is the principal source of the ore
currently being mined either as:
1.
Carbonate-rich
Mamatwan-type ore (38% Mn), which constitutes some 95% of the total ore
reserves, or
2.
Higher-grade
Mn Oxide-rich Wessels-type ore (>44% Mn), which is found in the northern
part of the field and constitutes <5% of the known reserves.
Manganese
ore is used in the steel making process primarily in the form of
silico-manganese and ferromanganese alloys. The world demand for manganese
depends directly on the requirements of the steel industry, with the price of
manganese ore having risen significantly in recent years.

The information in this
announcement, insofar as it relates to Mineral Exploration activities, is based
on information compiled by Geoffrey F Pigott who is a member of the Australian
Institute of Geoscientists, and who has more than five years experience in the
field of activity being reported on. Mr Pigott is a full-time employee of
the Company. Mr Pigott has sufficient experience which is relevant to the
style of mineralisation and type of deposit under consideration and to the
activity which he is undertaking to qualify as a Competent Person as defined in
the 2004 Edition of the 'Australasian Code of Reporting of Exploration Results,
Mineral Resources and Ore Reserves'. Mr Pigott consents to the inclusion
in the report of the matters based on the information in the form and context
in which it appears.
