Pakrut Gold Project

The Pakrut gold project lies within the southern portion of the Tien Shan Fold Belt, a belt of folded rocks that extends from near the Aral Sea in Uzbekistan through the northern part of Tajikistan into China and then into Mongolia. Pakrut is located northeast of the capital city of Tajikistan, Dushanbe, from which it can be accessed in around three and a half hours by road.

LLC Pakrut, a wholly owned subsidiary of Kryso, was granted an exploration and trial mining licence over the Pakrut Licence Area, which comprises the Pakrut and Eastern Pakrut gold deposits and a surrounding 6,300 hectare exploration area containing a number of other deposits and mineral occurrences, in April 2004. This licence is valid until 1 April 2014. The Pakrut Licence Area is located within the Tien-Shan Fold Belt, which contains the world’s second largest known gold resources after the Witwatersrand in South Africa.

The reserves of the Pakrut project, which total 1,257,454oz Au at a cut off grade of 0.5g/t (under the Russian classification system), were approved by the State Committee for Reserves (GKZ) of the Republic of Tajikistan on 15 December 2008. This approval gives Kryso the exclusive right to a full mining licence valid for 20 years.

A bankable feasibility study on the Pakrut Gold deposit has been completed, and the results of continuing exploration and resource development drilling by Kryso have been highly encouraging.

Kryso appointed the Beijing General Research Institute of Mining & Metallurgy (BGRIMM) to complete the Pakrut gold project bankable feasibility study. BGRIMM is a highly reputable Chinese consulting group active in the fields of mining engineering, mineral processing and metallurgy, and has completed substantial work for well known international companies including Kazakhmys, El Dorado Gold, SinoGold, ArcelorMittal and Griffin Mining. BGRIMM is ISO9000 certified.

In completing the Pakrut project BFS BGRIMM built on work previously completed by other consultants to Kryso including GeoLogix Mineral Resource Consultants (resources), GBM Minerals Engineering Consultants (metallurgical test work review and preliminary process design), Prime Resources (social and environmental), Scott Wilson Group (tailings dam design), SGS Group (metallurgical test work) and Turgis Mining Consultants (mining and infrastructure).

There are three additional mineralized systems within five kilometres of the main Pakrut gold deposit. These are the Eastern Pakrut gold deposit, the Sulfidnoye gold and silver prospect and the Rufigar prospect. For more information on the Sulfidnoye and Rufigar prospects please see the Pakrut Satellite Prospects section of the website.

Bankable Feasibility Study Highlights

Mine life 14 years with average gold production of 82,000 ounces per annum over the first 4 years
Life-of-mine operating costs US$377/oz

At a US$897/oz gold price the project would have:

  • NPV (10%) of US$121 million
  • IRR of 40%
  • Payback period of 3.0 years

At a US$1,250/oz gold price the project would have:

  • NPV (10%) of US$227 million
  • IRR of 58%
  • Payback period of 2.7 years

Figures are before tax and allowance for anticipated debt financing

Total capital required for development approx. US$108 million
Optimisation of project prior to construction expected to result in improved economics

By the beginning of 2010, over 20,000m of drilling had been completed by Kryso at Pakrut, over 1450m of pre-existing adit had been refurbished, over 600m of new underground development had been excavated, and over 32,000 samples had been analysed by Kryso’s laboratories in Tajikistan.

Metallurgical Testwork

Initial metallurgical testwork was carried out by Tajik Geology with reported gold recoveries, using rudimentary gravity recovery methods, of 47% to 98%. Consistently high gold recoveries of between 80% and 90% were attained using a combination of gravity methods and cyanidation. Further metallurgical testwork has been carried out by SGS Lakefield and BGRIMM which has confirmed the results of the work carried out by Tajik Geology.

 

Geological Setting

A large number of world class mesothermal gold deposits are hosted within the Tien Shan Fold Belt. The Pakrut area is included in this province, as well as in the rare-metal-polymetallic Zeravshan-Hissar belt of mineral deposits and the Kugiturinscky gold belt of low-sulphide gold-quartz mineralization.

The rocks surrounding the Pakrut Licence Area are dominantly metamorphosed Palaeozoic marine sedimentary formations with subordinate Mesozoic sediments and intrusive rocks. An Upper Ordovician green schist horizon is the most important formation in the area, as it tends to have localised zones of hydrothermally altered, gold bearing rocks. This green schist unit is reported to be the eastern extension of the gold bearing formations of western Uzbekistan where sizable gold deposits including Muruntau, Daugystau and Zarmitan are located.
