2. The Special Technical Control Department (Odborna technicka kontrola -CAMK)
at lora Zdar - Vykmanov (N51/K71) is responsible for the grading of the
uranium are. The ore is handled as follows.
a. When the ore is brought to the surface it is weighed in the carts by collector's
instruments and then transported to the Grading Department (a wooden hut),
- where it is tilted out on the concrete floor. There it is sorted out into
different piles and each pile is provided with a wooden beard to indicate
the origin of the ore. The ore is broken by hammers and put into special
wooden oases according to the degree of activity. The types of ore areas follows.
(1) muck ore, which is the purest.
(2) Brown ore, the second purest grade.
(3) Black ore called "soot", which is,sott, moist and sticky.

(4) Ore hidden inside the stones, the presence of which can be
ascertained only by the weight of the stones. This ore is called
Ucko (U-ore) and is the weakest in radioactivity.
(5) Deaf ore (Rlusiaa), which has no radioactivity and is transported
directly to the Special Technical Control Department.
(6) Ore contained in PbS (Galenit) in the form of veins or fine grains.
b. The ore, graded and in boxes, is taken by truck to the Special Technical Control
Department, where it is unloaded, measured, weighed in a speaial department
called RadiOmetrie, and stored in special boxes.
c. By means of conveyor belts the ore is transported to grinding towers,
where it is crushed. The grinding machines are cleaned3 after each crushing
in order to avoid mixing the various ores.
d. The crushed ore is put into metal barrels 70 by 50 cm. in size, with lids 20 am.
in diameter, which are shaken on special vibration nets. The average weight
of a barrel containing ore is 67 kg. If it contains pure ore the weight
is 130 kg.
e. The barrels of ore are shifted to the Shipping Storehouse, where the barrels
are closed and sealed and the lids provided with particulars such as number
of barrel, month and year, pit and section of origin, weight and radioactivity.1
The barrels thus marked go to the storage area and are shipped from there to the
USSR.
3. There are two methods of packing the ore for shipment to the USSR. Ucko
(U-ore) is loaded into closed freightcars and sealed, while the better quality
ores are loaded, while still in the barrel, into the freightcars, which are then
sealed.
4. Before the -ore is crushed it has to be turned over several times in order to get
an even quality. Then a sample from each pile is taken to the laboratory,
the samples are crushed into fine powder and this is tested and seht to the USSR
as a sample of the corresponding barrel.
5. Ucko (U-ore) which has been brought from the pits to the Special Technical
Control Department is put on the concrete floor and from there it is loaded into
wooden wagons, measured and weighed, put into piles, and shipped by freightcar.
If some ore of good quality is found among the Ucko the whole lot is sent
to the grinding towers and the procedure is the sane as for the Ores of better
quality.
6. The sealed freightcars are shipped from the Special Technical Control Department
to the Ostrov (N51/K70) station. The cars are assembled into special trains
which leave every three weeks for the USSR by way of Cierna. The average train
consists of 18 to 20 cars. Such trains have been seen passing through Cesky
Tesin (Q50/088).
7. Each train has a guard of SNB men who travel in a special car at the front, of the
train. Whenever the train stops at a station each car is guarded by an SNB man.
While in motion there are two-man guards at each end of the train mauling
light machine-guns ready for use. The engineers and firemen are civilians and trusted
members of the CP.
8. The freightcars used have special wide axles to which another set of wheels can be
affixed, enabling the train to operate on the broad-gauge Russian rails.

9, Cseehoelovakia has-been divided into sectors for -the -purpose of -prospecting for Urallillt
In each sect= a rubberitellmnis blown up lath local air, -which is then teitid in a
laboratciry. If the air being tested is found to contain radioactive elements,
the area is searched. In.cdrilliug, a special pneumatic drill called Grelius is used.
It is capable of drilling to a depth of 200 meters.
10. There are 300 people in the forced labor camp at Vykmanov.
