GEOPHYSICAL SURVEY IDENTIFIES DRILL TARGETS AT BAKIR TEPE PROJECT
KEFI Minerals, the AIM-quoted gold and copper exploration company with projects
in Turkey, is pleased to announce the results of a recently completed
pole-dipole Induced Polarisation ("IP")/Resistivity survey on its 100% owned
Bakir Tepe Licences in southwestern Turkey.
The IP survey has defined two moderately strong chargeability anomalies, one of
which the survey suggests has a strike length of over 900m, in what is
interpreted to be a very favourable setting for volcanic massive sulphide (VMS)
copper-gold style of mineralisation.
The northern anomaly is marked by continuous chargeability values exceeding
10mV/V, up to a maximum of 19.9mV/V. The anomaly has a strike length of
approximately 900m east-west and is up to 350m in width. The two dimensional
inversion models place the depth to the top of the chargeable source as greater
than 50m and up to 120m in places. This anomaly coincides with the down-dip
projection of the known copper-gold mineralisation in the area.
The southern anomaly is marked by continuous chargeability values exceeding
10mV/V, up to a maximum of 19.0mV/V. The anomaly has a strike length of over
400m east-west, is up to 250m in width, and is open ended to the west. The two
dimensional inversion models place the depth to chargeable source as
approximately 50m.
The IP responses are interpreted as being indicative of the occurrence of
potentially economically significant levels of sulphide mineralisation. KEFI
Minerals plans to complete an initial phase of diamond drilling to test the IP
anomalies at depth. Drilling of up to three holes, each to around 200m deep, is
scheduled for September 2008. Further drilling programmes will then be
coordinated based on the success of the initial phase of diamond drilling.
The alteration sequence observed at Bakir Tepe is typical of peripheral
alteration "apron" zones that form around the core of a massive sulphide
deposit. The geophysical IP survey was designed to explore for the presence of
sulphide mineralisation at depths of up to 250m below surface, in the vicinity
of the outcropping mineralised alteration zones.
KEFI Minerals was granted the Bakir Tepe Licences, covering a total area of 78
km2in south-western Turkey in June 2008. The area is prospective for
Cyprus-type VMS style of copper and gold mineralisation.
As reported previously, initial surface grab and channel samples have returned
values of up to 3.6% copper, 4.6 g/t gold, 67 g/t silver and 1,070 g/t zinc
from mineralised alteration zones at Bakir Tepe.
KEFI Minerals' Managing Director, Jeff Rayner, commented:
"The results of the IP survey at Bakir Tepe confirm our view of the potential
of the area to host significant copper-gold mineralisation and have provided
valuable data for planning the initial phase of drill testing. The three
planned diamond drill holes will test the possibility that the IP anomalies
represent part of an extensive hydrothermal system with the potential to host a
large tonnage mineralised body."

Notes to Editors:
KEFI Minerals commenced trading on AIM on 18 December 2006 and aims to create
shareholder value through the discovery and exploitation of gold and copper
deposits.
KEFI Minerals currently has the following nine exploration projects in Turkey:
1. At Derinin Tepe in the Western Anatolia Region, low-sulphidation epithermal
quartz veins have been identified with gold and silver mineralisation.
2. At Artvin in northeastern Turkey, extensive hydrothermal alteration and
gold and base metal mineralisation have been recognised in the project
area, as well as historical workings indicating potential for economic
mineralisation.
3. At Gumushane in eastern Turkey, areas of extensive hydrothermal alteration
have been recognised in the project area, as well as coincident areas of
interest identified through interpretation of Aster data.
4. Hasancelebi, in central Turkey, is prospective for high-sulphidation
epithermal gold mineralisation and Iron-Oxide Copper-Gold ("IOCG")
mineralisation.
5. At Karalar, in Central Anatolia, highly anomalous gold in stream sediments
have been identified in an area of historic base metal mines.
6. Muratdag, in the Western Anatolia Region, is prospective for Carlin-style
epithermal gold mineralisation.
7. Meyvali, in the Western Anatolia Region, is prospective for epithermal and
skarn related mineralisation.
8. At Yatik, in the Western Anatolia Region, low-sulphidation epithermal
quartz veins with gold and silver mineralisation have been identified.
9. Bakir Tepe, in southwestern Turkey, is prospective for Cyprus-type
volcanogenic massive sulphide (VMS) copper-gold mineralisation.
KEFI Minerals also has an extensive exploration database which contains
information about approximately 100 further prospective sites in Turkey. This
database provides the Company with a competitive advantage to identify
prospective areas for project generation in Turkey. Monitoring of the
exploration licence status of geologically prospective areas will be carried
out on an ongoing basis so that KEFI Minerals can acquire further exploration
opportunities as soon as they become available.
EMED Mining has agreed to provide technical and administrative systems and
personnel to KEFI Minerals on a cost-recovery basis, thus enabling KEFI
Minerals to reduce overheads and spend more on exploring Turkey and potentially
other countries in the region.
KEFI Minerals' Board of Directors is comprised of Mr. Harry Anagnostaras-Adams
(Chairman), Mr. Jeffrey Rayner (Managing Director), Professor Ian Plimer
(Deputy Chairman) and John Leach (Finance Director).
