Oxus Gold plc
Mineral Resources and Ore Reserves Statement
at 30 June 2006
LONDON: 30 November 2006 - Oxus Gold plc ('Oxus' or the 'Company') is pleased to
state an increase in JORC classified gold and silver Mineral Resources and gold
Ore Reserves at Amantaytau Goldfields and report on its Mineral Resources and
Ore Reserves statement as at the end of the Company's financial year.
The Ore Reserves show an overall increase in gold of 41,000 ounces as compared
to the previous year. Significantly, this is in addition to the 146,937 ounces
of gold mined during the year, hence the Ore Reserve ounces have been
replenished in excess of the rate of mining by the conversion of Mineral
Measured plus Indicated Mineral Resources have increased substantially by
743,000 ounces of gold and 14.48 million ounces of silver. This increase
provides a further platform for the Company's growth potential as it continues
to convert resources into reserves for future mining. Inferred Mineral Resources
have also increased substantially by 650,000 ounces of gold and 7.79 million
ounces of silver, and are planned to be upgraded by further exploration
During the year, 37,196 metres of exploration and development RC drilling, 942
metres of core drilling and 585 metres of trenching was completed on a number of
deposits of the AGF licence area. On the basis of this new information, enhanced
by data entry of Uzbek/Soviet sourced exploration results, resource modelling of
3 gold deposits at AGF has been completed. In addition, satellite based
structural and alteration interpretation of the AGF licence area has defined new
oxide targets. Significantly, Oxus has evaluated a number of deeper sulphide
extensions to the oxide pits and has increased the future growth potential of
The main Group changes occurred at Amantaytau Goldfields (AGF - 50% Oxus),
• Attributable Measured plus Indicated Mineral Resources within the AGF
licence area increased by 743,000 ounces to 2.49 million ounces of gold and
silver increased by 14.48 million ounces to 19.33 million ounces, and
attributable Inferred Resources increased by 650,000 ounces to 1.19 million
ounces of gold and silver increased by 7.79 million ounces to 8.02 million
• Attributable Ore Reserves within the AGF licence increased by 41,000
ounces to 1.47 million ounces of gold and silver decreased by 939,000 ounces
to 3.67 million ounces.
The changes at AGF described above in terms of the JORC Mineral Resources and
Ore Reserves were;
• Following exploration and remodelling, the oxide Measured plus
Indicated Mineral Resources increased by 5.0 million tonnes containing a
reduction of 42,000 ounces of gold and an increase of 1.48 million ounces of
silver, and the Inferred Mineral Resource increased by 1.38 million tonnes
containing 31,000 ounces of gold and 274,000 ounces of silver;
• Following exploration of open pitable sulphide mineralisation below
the existing oxide resources and the reduction in cutoff grade at Amantaytau the
sulphide Measured plus Indicated Mineral Resources increased by 26.9 million
tonnes containing 1.53 million ounces of gold and 27.47 million ounces of silver
and the Inferred Mineral Resource increased by 21.1 million tonnes containing
1.27 million ounces of gold and 15.3 million ounces of silver;
• Following mining depletion, orebody remodelling and block model
adjustment as a result of grade control the Carbon-In-Pulp Plant (CIP) and Heap
Leach Ore Reserves reduced by 1.72 million tonnes containing 297,000 ounces of
gold and 1.88 million ounces of silver. The remaining CIP ore is at a lower
average grade of 1.56g/t gold compared with 2.09g/t gold reported previously,
and the average heap leachable silver grade dropped to 43.70g/t, from the 68.37g
/t previously reported;
• Sulphide Ore Reserves increased by 4.24 million tonnes containing
378,000 ounces of gold as a result of a reduced cut-off grade to 3.5g/t gold
calculated for the new Amantaytau underground mine design, with a resultant
grade of 7.71g/t gold compared with 11.54g/t gold reported previously.
Subject to licence approvals at Ayirak and Tamdy areas in Uzbekistan and
international arbitration at Jerooy, Kyrgyzstan;
• The Company's attributable JORC compliant Mineral Resources (Measured plus
Indicated) are 41.69 million tonnes at 2.96g/t gold and 14.42g/t silver for
3.97 million ounces of gold and 19.33 million ounces of silver, and Inferred
Resources are are 32.96 million tonnes at 2.53g/t gold and 7.57g/t silver
for 2.68 million ounces of gold and 8.02 million ounces of silver.
• The total attributable JORC compliant Ore Reserves (Proven plus Probable)
for the Company are 18.91 million tonnes at 4.18g/t gold and 6.03g/t silver
for 2.54 million ounces of gold and 3.67 million ounces of silver.
• The total attributable JORC compliant Exploration Results for the Company
are 4.01 million ounces of gold and 36.40 million ounces of silver.
• In addition to the JORC resources, the attributable Soviet classified P1
category is 5.22 million ounces of gold and 158.91 million ounces of silver,
and Soviet P2 category is 6.93 million ounces of gold and 25.11 million
ounces of silver, which will be future targets for conversion to JORC
A detailed listing of results of all the exploration work carried out during the
year will be presented on the Company's website (www.oxusgold.co.uk), including
exploration drillhole results, the exploration trenching methodology and
results. In addition, an explanation of the resource classifications used will
also be presented.
It is the intent of the company to continue to define additional resources and
to upgrade the existing resources for conversion into reserves, with the aim to
assess the potential to extend or increase ore throughput at AGF's existing CIP
process plant. The possibility of further heap leach units to exploit lower
grade oxide material is also under consideration.
As part of the Group's long term exploration strategy, cost effective value
added exploration programmes are envisaged. Core drilling will be utilised for
specific projects such as deep sulphide drilling, Amantaytau sulphide 'superpit'
evaluation, geotechnical and metallurgical drilling. Oxus intend to continue
advancing the exploration of the AGF licence area to evaluate the remaining
targets in order to define the upside potential and develop a robust future
The current Oxus Group's resources and reserves are summarized below.
A detailed exploration year end report including the detailed tabulation of
resources and reserves will also be presented on the website.
The resources and reserves are stated in accordance with the AIM Guidance for
Mining, Oil and Gas Companies for reporting, and adopt the 'JORC Code'
(Australasian Code for Reporting of Exploration Results, Mineral Resources and
Ore Reserves prepared by the Joint Ore Reserves Committee) classification as
well as the Russian system of classifying resources and reserves where
applicable. In accordance with the rules, the total project and Oxus
attributable ounces of gold and silver are presented.
The resources and reserves stated in this report have been compiled by the
