Drilling Results at Artvin Project

DRILLING RESULTS AT ARTVIN PROJECT, TURKEY
KEFI Minerals, an AIM-quoted gold and copper exploration company with projects
in Turkey and the Kingdom of Saudi Arabia, is pleased to announce the assay
results from its recently completed diamond drilling programme at the Company's
Artvin Project located in the Eastern Pontide Belt in northeastern Turkey.
The Artvin Project is a joint venture with a subsidiary of Centerra Gold Inc.
("Centerra"), which is currently funding exploration in order to earn up to 70%
of the Artvin Project upon expenditure of US$6m. KEFI Minerals is the manager
of the joint venture.
The objective of the 2009 drilling programme was to further test at the Yanikli
Prospect, the extensive alteration system, with coincident gold, silver and
base metals geochemical anomalism; and a large (1,250m x 800m) induced
polarisation ("IP") chargeability anomaly.
All four diamond drillholes totalling 1,125m intersected wide intervals of
strongly propyllitic- to phyllic-altered andesitic volcanic rocks with
widespread disseminated and vein-style pyrite +/- lesser
sphalerite-galena-chalcopyrite mineralisation. Anomalous assays include 1.95m
at 0.64g/t Au and 25.2g/t Ag from 137m. Hole AYDD007 returned 1.3m at 2.26% Cu
from 301.8m and 1.6m at 1.61% Zn from 213m. Hole AYDD008.returned the widest
zone of anomalous zinc mineralisation viz. 67m at 0.25% Zn from 88m, including
2m at 1.12% Zn from 124m. The chargeability anomaly is explained by the high
levels of alteration-related pyrite in the host andesitic to dacitic volcanic
rocks.
The style of alteration and mineralisation suggests that the property has
potential for volcanogenic massive sulphide copper-zinc deposits and
porphyry-style copper-gold deposits. Surface geochemical sampling and
geological mapping has outlined an extensive altered zone, comprising strongly
propyllitic- and phyllic-altered mafic to felsic volcanics, hosting vein-style
and disseminated gold, silver base metals mineralisation. Soil, rock chip and
channel chip sampling delineated a series of gold, silver and base metals
anomalies over a 1.75km x 1.50km area, with maximum soil values of 2.4g/t Au
and maximum rock chip values of 5.1g/t Au being returned. These geochemically
anomalous zones, with selected geological targets, were tested in late 2008 by
diamond drilling. The best intercepts recorded from the 2008 drilling programme
were 2m at 20.9g/t Au, 14m at 1.0g/t Au, 64m at 0.35% Zn and 44m at 0.57% Zn.
Petrologic analysis of drill core from hole AYDD006 identified dioritic
intrusive rocks. This, along with other rock types and alteration assemblages,
suggests that the Yanikli Prospect forms part of the distal portions of a
porphyry-style copper-gold system. Examples of this type of system occur at
Berta and at Ardala, 15km and 25km southwest, respectively, of the Yanikli
Prospect.
KEFI Minerals' Managing Director, Jeff Rayner, commented that:
"Results from the initial diamond drilling programme at Yanikli in 2008 were
encouraging. The results from the second-phase diamond drilling programme in
2009, whilst of a lower grade, indicate that our understanding of the nature
of, and controls on, the alteration and mineralisation is increasing. It is
important that we continue to develop that understanding and we are now
evaluating the results of this drilling programme, in conjunction with
Centerra, to plan the next phase of work to be carried out on the Artvin
Project.
Description of Second-Phase Drilling Programme
The second-phase diamond drilling programme at the Yanikli Prospect was
completed on 15th December 2009. Four holes were completed for an aggregate of
1,125.2m of HQ core. The drilling was carried out by Pozitif Sondaj, an
Ankara-based drilling contractor. Detailed lithological logging of the drill
core was undertaken and intervals with alteration +/- mineralisation +/-
veining were selected for sampling. Half HQ core samples were collected at 1-2m
intervals with 469 samples (including 18 standards) being submitted to ALS
Chemex in Izmir for analysis.

About the Artvin Project
The Artvin Project is located in the Artvin Province of northeastern Turkey and
comprises 15 tenements, which cover approximately 254km2 within the eastern
portion of the Eastern Pontide Belt. The Eastern Pontide Belt is a major
metallogenic province in the eastern Black Sea coastal region and is
prospective for VHMS deposits, porphyry copper-gold deposits and epithermal
gold-silver mineralisation.
The Artvin Project comprises 15 tenements, which cover approximately 254km2,
and is subject to a Joint Venture agreement with a subsidiary of Centerra Gold
Inc., a Canadian-based gold mining and exploration company listed on the
Toronto Stock Exchange.
About KEFI Minerals
KEFI Minerals commenced trading on AIM in December 2006 and was formed with the
aim of creating shareholder value through the discovery and exploitation of
gold and copper deposits.
In Turkey, KEFI Minerals currently has the following exploration projects:
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. Artvin is a joint venture operated by KEFI Minerals and
funded by a subsidiary Centerra Gold Inc, who has the right to earn up to
70% interest in the property by spending US$6 million.
3. Bakir Tepe, in southwestern Turkey, is prospective for VHMS polymetallic
