Resource estimation

Tin
On the territory of the Okrug 83 deposits of tin are found, mostly complex tin-and-tungsten, including:

1basic - 11,
2gravel - 72.

Estimated and probable reserves of tin in the Chukotka Autonomous Okrug (as in 01.01.2006) are as follows:

Mineral	Deposits			Probable reserves
Mineral	Total	In-place reserves	Off-balance reserves	Total	Р3	Р2	Р1
Tin (thousand tons )	425,2	373,9	51,3	508	57	185	266
Tungsten (thousand tons )	75,1	64,6	10,5	168,3	-	122	46,3

The greater part of tin and tungsten deposits is concentrated in the Chukotka metallogenic zone. They are situated relatively close to each other in the north of the Okrug. The largest are basic reserves (Pyrkakayski Stockworks, Yioultin, Valkumei, Ekug, Svetloye, Lunnoye). The average percentage of tin in the ore is 0.23%.

The largest deposit is Pyrkakayski stockworks.
Location: Chaoun District, 86 km south-eastwards of the town of Pevek.
Characteristics: stockwork group is constituted of 7 deposits with the Okrug’s largest reserves of ВС1С2 category, ore revertible.
In-place reserves: 270.800 tons, or 82% of total Okrug’s reserves; В+С1 – 259. 8 thousand tons, С2 – 11.2 thousand tons.
Average percentage of tin in the ore: 0.23%
Exploration: open cutting is possible.
Slump in tin prices and sharp contraction of domestic market that took place in 1990s resulted in stoppage of tin production at the Valkumei and Yioultin deposits, as well as at numerous tin placers. All such tin deposits have been transferred to state reserve.

Platinum group metals
Probable reserves of the platinum group metals in the Okrug are located in the Anadyr-Kiryak system, which is characteristic of gold, mercury, rarer copper, chromite and tin-and-silver mineralization, as well as of some placers of gold and platinoids.
Advance geochemical search and prospecting works performed in recent years in the Mainitski-Khatyrski platinum-beating area brought new data on metallogenic potential and perspectives of the territory in finding basic deposits of gold, platinoids and chromites; a forecast estimation of these deposits has been provided. Based on recent information, promising metallogenic areas needing a more detailed analysis of their geologic-structural, geochemical and search characteristics have been singled out. These are Algan, Velikorechinsk, Mainits, Rytgyl, Alkatvaam, and Econai areas.
In addition to this, probable reserves of platinum group metals in the Peschanka complex molybdenum-copper-porphyry formation deposit are estimated by the Р1 category as follows: Platinum - 16.2 tons, palladium - 125.5 tons, rhodium - 17.6 tons.

Silver
Pure silver deposits have not discovered, but still there are reasons to think that there are reserves with big concentrations of silver. Silver as a co-product is found in many proven gold and tin-silver deposits. Estimated on-site deposits amount to 1087 tons including:

1В+Сi – 45.6 tons – 1041.4 tons,
2C2 – 1041.4 tons.

Probable silver reserves as estimated on 01.01.2003 are set in the amount of 8500 tons by the Р2 category. These are located in two metallogenic areas:

Verkhne-Yablonski area with gold and silver mineralization - 2300 tons,
Pettymel-Oleptitinsky area with silver and polymetallic mineralization - 6200 tons.

The profitability of industrial exploration of silver-bearing deposits with on-site reserves is judged by economic value of basic minerals, gold and tin.

Tungsten deposits
The Government Statement of Balance includes 28 tungsten deposits on the territory of the Chukotka Autonomous Okrug, including:

gravel - 17,
basic - 11.

On-site reserves are contained in gravel and basic deposits that by the ВС1С2 category total 63,700 tons, with average percentage of WO3 of 0.06%.
Gravel deposits of the Yioultin District allow open cutting, and three of them have reserves for deep-mined output. Also, gold placers of the Lenotap River contain tungsten trioxide allowing for drag extraction.
In 7 locations with open cutting in the Chaoun District tungsten trioxide is found as a co-product for tin.
In 1992 tungsten production was quitted by the same reasons as production of tin.

Copper
Presently no copper extraction locations have been set in the Chukotka Autonomous Okrug.
However as a co-product copper may very well be produced. The most promising in this respect is the Peschanka complex copper-porphyry deposit. Apart from copper, it is proved to contain considerate reserves of molybdenum, gold, silver and platinum group metals.
Exploration work of search and estimation stage have been performed on the Peschanka deposit, mineralization was explored to 700 m depth. Results of this work served as base for estimating probable reserves of Pi category, these made up 1.350 billion tons of ore containing the following:

8.3 million tons of copper (0.61% percentage),
200,000 tons of molybdenum (0.015%),
435 tons of gold (0.32 g/ton),
5000 tons of silver (3.7 g/ton) and
159 tons of platinum group metals (0.12 g/ton).

In connection with steep rise of copper price (it now costs more than $7000 per ton) industrial value of this deposit is worth reconsidering.
Additional copper reserves were found during assessment research of large territories, very promising from the point of view of copper-sulfur formation reserves.

COMMENTS

The program of economic development in Chukotka can be carried out, considers vice-premier of government CHAO M. Sobolev.

First of all, the long-term program leans on resources of peninsula. Let’s begin that geological resources of Chukotka are explored today on 10 %-17 %. The next regions are explored much better. And even on these, tentative estimations resources here can be found. The proved resources of gas on the Priosernoe deposit - 7,3 billion cubic meters. Oil resources are estimated approximately in 10 million tons, the proved stocks make 4 million tons of them. They are dispersed on small Fields, such, as Hatirskoe, where extraction is conducted by "Sibneft" company. But it is not necessary to dismiss a shelf – it’s insufficiently studied yet, but there are data, that it’s resources can make up to 14 billion tons of conditional fuel. Exxon Mobile Company in similar ice conditions, in Baffin bay has constructed 7 platforms. What prevents to construct them here?

Reindeer breeding can be profitable: E. Marochkin acting on the head of agriculture and foodstuffs department makes comments.

There was a moratorium on an industrial slaughter of deers in district till 2006. But now it is removed, farms have allocated a contingent for commodity slaughter this year. It is planned to hand over in a trading network about 9 thousand deers this year. Within the limits of national project the agrarian and industrial complex have got slaughter area on terms of financial leasing which is assembled in Kanchalan. Basically its value is in that correctly cut production will receive a trade look and will answer all established norms. The livestock of deers for September, 1st - from above 183 thousand. It’s below the level of 1990 (490 thousand heads), nevertheless, in Chukotka a livestock grows on faster rates, than on Yamal, and it’s our main competitor. Potential market - not only Vladivostok, but also Japan, Korea, China. Reindeer breeding is, at least, preservation of a traditional way of life of native people and food safety of region and when sales volumes become great enough, branch can turn in profitable.
