Annual report for EL 25694 Central Mount 18 September 2009 to 17 September 2010

Abstract

During a brief visit to Tianda's Central Mount project by Terra Search staff in 2008, encouraging uranium samples were collected and gave results of up to 89ppm of the element. These results justified a more detailed investigation. During April 2010, EL 25694 was investigated by a Terra Search geologist and field assistant. Their objective was an area near the western boundary of the tenement, where uranium anomalism had been found in ferruginized sandstone and in nearby ironstone veins. While in the area, the crew took 85 rock chip and 174 soil geochemical samples. Several stream calcrete deposits were discovered, as well as a complex of ironstone veins. The disposition of the ironstone veins appears to be controlled by a major fault and its conjugates. The northern area, centred about a radiometrically-active vein, has been designated as the Archimedes prospect. A second, more scattered southern anomaly has been dubbed the Bragg prospect. Much of the area was covered by colluvial and alluvial deposits. Outcrop, subcrop and lag were mapped, as were structural data. These data were recorded on hand GPS units and downloaded onto a computer in the field. As the dykes were ferruginized and probably magnetic, a detailed ground magnetometer survey was performed, of 120 line-km over 3.8km2. After processing, this revealed tabular bodies parallel to the dykes, as well as a number of cylindrical bodies, probably dolerites. Neither the tabular nor cylindrical bodies have any surface expression. ICP-MS of the rock chip samples returned a number assays in the Archimedes prospect in the range 100 - 299ppm of uranium, over a strike length of 160m. Further south, in the Bragg prospect, they were lower but still gave values of 40 - 70ppm over a strike length of about 700m. No other element gave commercially-significant results, with the possible exception of iron. Uranium soil geochemical assays were in the range of 3 - 6ppm, with a few higher returns in the vicinity of the outstanding rock chip assays. In July 2010, a return visit was made to the prospects. Apart from detailed rockchip sampling of 11 traverses, a gamma ray spectrometer survey was performed on the same traverses. Also, magnetic susceptibility determinations were undertaken of all of these samples, as well as of other rock specimens in the tenement. Altogether, an additional 149 rock chip samples were taken, of which 145 had gamma ray spectrometry performed. An additional 50 locations on a twelfth traverse also had spectrometer and magnetic susceptibility data recorded, but were not sampled for geochemistry. It is recommended that a program of reverse circulation drilling along the strike of the various ironstone veins and magnetic anomalies. A total of seventeen holes, generally oriented in a northeasterly to southeasterly direction, is planned. These will be at a dip of 60 degrees and up to 200m drill depth.
