Kyrgyzstan is a mountainous country in central Asia.
It is independent, politically and economically stable,
and a member of the World Trade Organisation. The country
has a wide variety of mineral occurrences and has been
encouraging external investment in mineral exploration
and mining over resent years. Interest by foreign investors
has focused chiefly on Tien Shan gold deposits, one of the
main examples being the development of the Kumtor deposit
by Centerra Gold Inc.
Kyrgyzstan has considerable potential for the following
types of gold and platinum group metal deposits:
• Placer deposits: formed by the concentration
of heavy minerals, such as gold and PGMs, by water action
in riverbed sands and gravels. Such deposits are often
preserved in alluvial terraces related to ancient drainage
systems. These deposits are near surface and mined by
open-pit or dredging methods.
• Orogenic gold deposits: associated with
gold-bearing quartz veins of hydrothermal origin formed
during major mountain building episodes in the earth’s history.
They are often high grade and amenable to both open-pit
and underground mining.
• Porphyry copper-gold deposits: formed during hydrothermal
alteration of porphyritic granitic intrusions (so called
because they contain large crystals in a finely crystalline matrix)
associated with the margins of continental plates. These are
generally fairly low grade, large tonnage, bulk
