Preliminary report on the Yenberrie uranium prospect, Northern Territory

A little torbernite, reported to be associated with cassiterite, was discovered at the Yenberrie prospect, late in 1952, by Messrs. R. Young and S. Mazlin, members of a syndicate operating a battery to treat tin ore, near Mt. Todd. The area was mapped during May 1953, on a scale of 100 feet to an inch, by D.E. Gardner and N.O. Jones. The prospect was tested for radioactivity with an Austronic ratemeter, and count rates exceeding three times the local background were obtained at four localities along the main shear zone over a length of 250 feet. Samples were obtained from shallow pits and shafts sunk at three of the four localities. A plan of the area and locality maps accompany this report.
