~S~'arY~ The following report gives information from two news
thataaches appearing in the same issue of the paper. One disclosed
geological survey of the Ta-yeh mining area last year was
unsatisfactory and a resurvey was required to obtain "reliable data"
for construction plans; the other describes the discovery of a large
sedimentary manganese ore bed in the T'an-hsiang manganese mining
area.]
Work of Surve Team
To provide the reliable data for plans to begin cons?ruction of China's
second iron and steel center, the members of the No !29 geological survey team
of the Minist y of Geolo,ry, who are survcyinr, in the Ta-yeh mining area, are
presently speeding up all types of worl; to complete their survey report on the
Ta-yeh mining area before the end of March 1954.
Before the end of 1953, the survey team "successfully" completed the geo-
logical and topographical surveying work of tt~e Ta-yeh mining area as well as a
report on geological surveying of the surrounding area. Subsequently, acting

pletion of the geological survey report nn the Ta-Peh miningaareasbyrt}~chend of
March 1951 ,
In a certain mountain area at Ta-ye}~, the worF;ers of the No 28 drilling
machine of the advanced drilling e.+cploration team, according to drilling theory,
drafted a detailed production chart of their accomplishments and aims. By
implementing Soviet methods and past experience, they have already surpassed
their quota by 1+1 days and have completed their drilling exploration for the
first quarter of the year. To reach the ton of cliffs several tens of metres
high to obtain samples, the geological. work personnel managed to put up a rope
laddc:, thus advancing the wort, of altitude sampling.
Surveying personnel working out in the cold open desert country are also
progressing with their work. Even thou~,h some men suffered from frozen hands
and feet, they obstinately continued with their work an3 have already success-
fully completed their ,jobs. In tt:e past, tine chemical testing laboratory has
frequently been unable to meet tiie :?equirements of other departments, but it is
paw improving its work, and its efficiency has increased by 25 percent and the
quantity and quality of work :;as been improved. '_ince various workers are putting
forth a united effort and are closely coordinating their activities, the compi_
lation of the geological survey report oi' the Ta-yeh mining area has been accel-
erated.
Large Manganese OrE Deposits
n T'an-hsianr Area
The Government has discovered a large sedimentary manganese ore bed i,i the
T'an-hsiang manganese mining area. Prel~minar,; irvestigatlons ant chemical exam-
ination show that this new ore deposit is not only large but is also on a level
plane so that it can be surface mined. Moreover, t're ore is of uniform compo-
sition. ManGanese is a very important raw material for the iron and steel industry,

The 'P'an-hsiang manganese. mine, xhich began operations in 1916, is a famous
oxidlzed manganese mine. Originally, beneath the oxidized manganese ore of this
mine was a layer of rocY, which resembled limestone, and people thought that it
was limestone. At the end of November of 1953, Hou Te-feng, a specialist of the
Ministry of Geology, came to the mine to examine the deposit. He examined and
surveyed the area and concluded that the deposit was of the sedimentary type.
According to geo_~gical scientific calculations, it was quite possible to have
Primary manganese ore beds under oxidized deposits. Therefore, on the basis of
the past erroneous assumption that this strata actually was limestone, he in-
structed the chemical 7sboratory of the T'an_hsiang manganese mine to conduct
further chemical analysis. Results of the chemical examinations show that what
was originally recognized as a limestone (calcium carbonate deposit is actually
a high-grade manganese ca*-bonate ore. At present, the T'an-hsisng manganese
mine is preparing to advance surveying work in order to increase future produc-
tion.
