In administrative respect Belanovskoye jaspilite deposit is situated in Kremenchug region Poltava district, near railway platform Belany, in 20 km north-east from Komsomolsk and in 25 km east from Kremenchug.
Deposit is opened as a result of exploration works performance by Kremenchug Geological Survey Expedition in years 1970-1972. The reconnaissance was held in years 1973-1974 and detailed exploration up to depth 700 m – in years 1975-1979. Kremenchug Geological Survey Expedition performed the jaspilite follow-up exploration of Belanovskoye deposit subformation K23, K25 and bench K233.
Belanovskoye deposit borders on Yeristovskoye jaspilite deposit in south, in north – on Galeschinskoye deposit.
Belanovskoye deposit forms a constituent part of Kremenchugskoye iron-ore area, situated in north axial region of Orehovo-Pavlogradskaya suture zone, which divides Ingul’skiy and Srednepridneprovskiy megablocks of Ukrainian shield.
Deposit geology and its flanks are built of pre-cambrian formations of supercrust mesoarheyskaya – horse-verhovtchevskaya and paleoproterozoic – krivorozhskaya series, and, besides, granitoids of dneprovskogo and kirovogradskogo complexes. Residuum of Mesozoic age overlies almost widespread on the basement rocks. The residuum is overlapped by soft aqueous sediments of Paleogene and quaternary period with mean accumulation 92 m.
Main minerals of Belanovskoye deposit are magnetite iron ores. Within deposit one can separate four industrial ore reserves of jaspilite subformation: К22, К25, К27 and bench K233. According their chemical-mineralogic composition, they are divided into two main forms: magnetite and cummingtonite-magnetite. Magnetite quartzite in its turn is divided into two subvarietis: red- and greyeutaxitic.
Redeutaxitic magnetite quartzite occur in maximum quantity in bottom and top benches of subformation К22, and, besides, in top bench of subformation К25 and below subformation К27. Mineral composition: quartzite (40-60%), magnetite (25-60%), hematite (2-10%), cummingtonite (0-7%), green biotite up to 6%, secondary dolomit-ankerite (up to 15%). Redeutaxitic magnetite quartzite is most brush on deposit. Their average iron grade makes up 35,15-36,07%, magnetite 27,06-28-24%, hematite 3,4-3,5%, silicate and carbonate 3,99-4,26%.
Greyeutaxitic magnetite quartzite builds up middle bench of subformation К25 and К27. Mineral composition: quartzite (35-60%), magnetite (18-35%), cummingtonite (2-8%, seldom up to 10-35%), riebeckite (1-12%), green biotite (2-8%), colorless mica (1-2%), iron carbonate, essentially chapped, (5-15%). Average grade of total iron in greyeutaxitic magnetite quartzite makes 32,8%, magnetite 24,0%, hematite 2,45%, silicate and carbonate 5,7%. Cummingtonite-magnetite quartzite coincides with subformation К23. They form beds and significant alternations of little accumulation in subformations К25 and К27. Mineral composition: quartzite (35-60%), cummingtonite (10-35%), green biotite (1-10%), secondary – carbonate (3-15%), chlorite (up to 5%). Riebeckite and colorless mica can be quite often seen in rocks. Magnetite concentrates, mainly (up to 75%), in ore bands with accumulation 1-3 mm, more rarely up to 5-6 mm. Cummingtonite-magnetite quartzite are sensibly less ore-bearing, as average grade of iron in bench makes 25,57%, magnetite – 15,51 %. Confidence estimation is fulfilled by variety between reserves assessment results, earlier confirmed in USSR State committee for reserves, and measured reserves in present work, according to demands of Australasian system JORC.
Jespilite reserves of Belanovskoye deposit are confirmed by USSR State committee for reserves in 1979 with a protocol No 8366 in quantity:

Galeschinskoye deposit of high-grade iron ore was discovered by Kremenchug Geological Survey Expedition in 1950. Geological exploration of deposit commercial evaluation was carried out in 1950-1956 by Kremenchug Geological Survey Expedition. In 1956 while drafting final report after completion of all exploration works, ore reserves of the deposit were confirmed by USSR State committee for reserves with minutes No 1551 dd 1956-12-25. Ferrexpo Belanovo Mining LLC has a license for bucking ore mining of Galeschinskoye deposit. In administrative respect Galeschinskoye deposit is situated in Kremenchug region Poltava district at 20 km north-east from Komsomolsk and at 30 km east from Kremenchug.
Aimed to fulfill a complete illumination of Galeschinskoye deposit ore-bearing, Kremenchug Geological Survey Expedition performed detailed exploration in 1976-1983, then in 1983-1991 – preliminary exploration of high-grade iron ore in depth interval 600-1500 m with reserve evaluation of commercial categories. In 1991 Kremenchug Geological Survey Expedition drew up “Report concerning preliminary exploration of Galeschinskoye iron-ore deposit in depth interval 600-1500 m”. In geological-structure relationship Kremenchug iron-ore region is one of the allotments of north-east flank of Ukrainian shield, in zone of its suture with Dneprovsko-Donetskoy depression. Galeschinskaya synclinal is considered to be main structural element at deposit. Its strike extension exceeds 26 km. It is one-limb fold along the strike, with eastern limb. The western flank dips 75-80°. Ore field of Galeschinskoye deposit high-grade iron ores is situated on eastern limb of Galeschinskaya synclinal. Fold bend sinks to the north at 15-60°. Fold width makes 1,3 km, strike of bend limbs is north-south. Ore reserves of Galeschinskoye deposit form a tape with extent about 4 km. Two structural sequences participate in deposit geology: lower, consisting of Precambrian crystalline rocks, and upper, formed by aqueous rocks of Mesozoic and Cainozoic ages. Total assumption of soft mesocenozoic sediments within deposit makes from 100 m to 295 m, at average 150 m, increasing southward. Main minerals at Galeschinskoye deposit are high-grade iron ore subformation К22. Jespilites of subformations К22, К23, К25 have subordinate value, i.e. demand preliminary separation. According the minutes No 1551 dd 1956-12-25, one should take oxide jespilites reserves, including deposits of high-grade iron ores, to be outbalance. Among high-grade ores, taking into consideration mineral composition, following natural blond metal should be separated:
Martite ores confine to redeutaxitic quartzite of subformation К22. Dark-color ores with blue shade, almost always thin banding appears in them. In mineral ratio martite, iron mica, hematite, quartzite, clays, magnetite is present in ores.
Chloritic-martite ores represent banded formations, ore bands of black color interstratify with drab-green chloritic bands.
Dispersivehematite-martite ores are associated with martite greyeutaxitic quartzite and developed, essentially, in middle bench of subformation К22, mineralization in subformation К21is also presented by these ores, they dominate on deposit. Martite and dispersive hematite (hydrohematite) are playing a key role on ore composition, martite assay makes 70 – 80%, hydrohematite average grade is 10 – 20%, sometimes rising up to 30 – 40%.
As recrements one can see quartz, clays, hematite and carbonates.
Dispersivehematite ores are mainly located in subformation strata К23, they represent laminated claylike formations with cherry-red color. Ores have in their mineral composition following: mouldy fine dispersed hematite, martite, quartz and clays. Hematite is main mineral, martite – unavoidable and considerable recrement in hydrohematite ores, non-metallic recrements in hygrohematite ores are consistently in appreciable amount.
Carbonate-martite ores can’t be seen at deep, developed northward of deposit, just below trias. They are characterized by significant density and hardness; ores are monolith, with no distinct lamination and banding, dark-grey color, seldom brownish black. In mineral ratio martite, magnetite, carbonates, quartz, pyrite, apatite, kaolinite and ferrum oxide is present in ores.
