...last week's Science Magazine, Dr. D. B. Shimkin of Harvard's Russian Research Center reported on a uranium-prospecting trip he has made through Russian geological literature. Pay dirt, he said, has been found all the way from the Ukraine to far eastern Siberia...
...long ago as 1900, according to Shimkin, the Russians began looking for radioactive minerals. The best find was at Tyuya Muyun in the Fergana Valley of Central Asia, 200 miles east of Tashkent -where a mine was opened in 1908. By the end of 1913, it had produced 1,044 tons of ore containing vanadium, copper and about .82% of uranium. At 26 pounds of U-235 per atom bomb (a current guess), this early production could have yielded theoretically enough "fissionable material" for four bombs. The Tyuya Muyun mine was still producing in 1936, when it (and some radioactive...
None of the geological literature quoted by Shimkin is later than 1944. What the Russians may have found by frantic searching since that time, Shimkin does not guess. But he believes that the uranium deposits found before the war in the Fergana Valley alone "appear to provide a possible basis for the development of atomic power in that region...
