Geology

Regionally, our licences lie within the Tien Shan gold belt. Locally they are within the Turkestan-Alai gold-polysulfide ore belt. The Aprelskoe deposit occupies the central part of the Almalinsky ore field and is located in the foothills of the High Turkestan Mountain Range. The fault on which the Aprelskoe deposit and the Karachokinskaya field lie is confined to intrusive formations of gabbro-monzodiorite-syenite composition of Permian age. The fault is known for containing gold ore deposits of various types and formations, as well as the ore of tungsten, bismuth and rare earths.

The Aprelskoe deposit and Karachokinskaya field areas have a complicated fault framework, controlling placement of several gold-bearing veins fractured into zones with different directions. In many respects the areas are similar to a number of well-known known fields which are currently under development in the western regions of the United States but such ‘Carlin-type’ gold deposits are comparatively rare in Central Asia. However, some ‘Carlin-type’ deposits have been found during the last decade in the ore regions of Tajikistan and Uzbekistan, countries which border the Kyrgyz Republic. On the basis of these similarities, the Directors are hopeful that heap leaching will be an economically viable form of recovery.

Within the Aprelskoe deposit, there are two types of gold mineralization: hydrothermal-metasomatic (in propylitized syenites) and hydrothermal (in quartz-barite-sulphide veins), each with different structural and morphological types and composition.

The Aprelskoe deposit is divided into three principal sites: (i) Centralny, (ii) Rodnikovy and (iii) Medny. Centralny is further divided into five zones: (i) Bonanaza, (ii) Vostochnaya, (iii) Zelenya, (iv) Danbal-Maki and (v) Nos. Mining of the Bonanaza and Vostochnaya zones is expected to be by underground methods because of the thin nature of the mineralisation. The mineralisation of the gold at the Medney site is oxidised and of relatively low grade. This is seen as a potential open pit mine.

The Karachokinskaya licence covers the same geological trend which hosts the Aprelskoe deposits. Initial prospecting, which has included examination of satellite and aerial images of the area, surface examination and some trenching, has identified a number of anomalies within the trends which we consider to be highly prospective for the presence of gold. Taken together, the licences encompass four of the 96 deposits and ore manifestations identified in a 2007 government study of the Kyrgyz Republic’s gold resources.
