About 223 million tenge was allocated for the exploration of rare earth metals at the Khorgosskoye site in the Almaty region, reports publication "SK News" with reference to KazTAG. "Customer – RSU "South Kazakhstan Interregional Department of Geology of the Committee of Geology of the Ministry of Ecology, Geology and Natural Resources of the Republic of Kazakhstan "Yuzhkaznedra"; name - geological exploration work; additional characteristic – prospecting for rare earth metals at the Khorgosskoye site; planned amount – T222 768 750", – it is said in the description of the lot posted on the public procurement portal.
Acceptance of applications for participation in the competition has already started and will end on May 6. "Work on the project "Search for rare earth raw materials within the Khorgos massif" will be carried out in the northern part of the Panfilov district of Almaty region, within the Birlik rural district. Work on the project will focus on the area of geological diversion, which is planned in the known areas of the output of the leucogranites of the Khorgos complex and its exocontacts, as well as metasomatites along the periphery of the massif, on the area of the sheet L-44-125- B", – it is said in the technical specification files for the competition. It is noted that the territory is located between the mountains of the Border Dzungaria and the Eastern Tien Shan.
"Its northern part is occupied by inaccessible high mountain ranges and individual mountain ranges (spurs of the Birohoro ridge), and the southern part is an intermountain depression, along the bottom of which the Ili River flows (beyond the southern border of the territory). The prevailing absolute height of the mountains is 2-4 thousand m. The highest point of the territory – the height of 4370 m is located in the northwestern part of the sheet L-44-125, north of the work area. The ridges of the mountains are wide, wavy, the tops are mostly rounded, less often sharp, peak-shaped. The slopes are steep, often steep, rocky. There are especially many rocky cliffs in the north of the territory, where their height reaches 600-800 m, and the length is 2-4 km. The peaks and slopes of the mountains from a height of 3.5 thousand meters are covered with eternal snow and glaciers. The southern slopes of the mountains facing the Ili Valley are much higher, but are cut by a dense network of gullies and ravines, as well as by the channels of drying watercourses," – specified in the documentation. It follows from the description that in 1934-1935, manifestations of molybdenum, tungsten, bismuth and polymetallic mineralization were discovered in the basins of the Khorgos, Chizhin and Usek rivers, and after a number of works in 1969, exploratory work was carried out on the newly identified beryllium-tungsten-tin Watershed manifestation, which was given a promising assessment. In 1979, case studies were conducted to identify rare metal complexes associated with the mineralization of mercury, gold, tin, and tungsten and promising sites were identified, and in 1986, search work was completed within the Ushkol search area, which resulted in the discovery of tungsten manifestations of Alexandrovskoye. In 2014, the generalizing work "Geological and mineragenic mapping of the Tekeli-Useksky district, sheets L-44-124, 125" was completed, where all known data on rare-metal-gold-polymetallic metallogeny of the district were summarized.
"The rest of the geological work did not have a special focus on the study of rare metals and concerned these metals due to the complexity of the research. Of the types of studies used, the most informative for rare earth elements are the results of shlich surveys, for tungsten, tin and bismuth – the results of lithochemical surveys, and for volatile elements (lithium, beryllium and others) – the results of hydrochemical studies, furrow and geochemical testing," the documentation says.
