AB  - Thundelarra Exploration Ltd has conducted a analysis programme on samples from the NTGS core facility during February 2007. All holes sampled were located within the applications held by Thundelarra (or its subsidiary Element 92)in the Ngalia Basin. A total of 254 quarter-core samples (mostly on 1m intervals, taken from holes drilled by AGIP, were analysed by Ultratrace Laboratories in Perth for U, V, Se, Cu, Pb, Zn, Ni, Co & As using mixed acid digest with an ICP finish (Ultratrace Job# u94553. Samples with high U were prepared with a sodium peroxide fusion. The results failed to repeat the anomalism demonstrated by the earlier AGIP sampling in YRD66 (AGIP: 5248 ppm U3O8 from 162.5-163 vs THX: 23.5 ppm U from 162-163, which highlights the highly localised nature of the uranium mineralisation in that hole. The results from Y206RD proved to be closer to the original analyses (AGIP: 1240 ppm U3O8 vs THX: 1076.75 ppm U, both from 197-201, indicating that the mineralisation is probably more disseminated in this hole. Hole Y24RD & Y26RD also showed relatively high-order zinc anomalism (Y26RD: 12m @ 0.11% from 135m & Y24RD: 1m @ 0.287% from 195m. The zinc-anomalous interval in Y24RD was later found to be associated with a chloritic metasediment (very poor recovery)that represents a zone of intense dynamic deformation. Very low order uranium anomalies correlate with the elevated zinc(e.g. Y24RD: 1m @ 12 ppm from 195m. Both the uranium and zinc are probably primary in origin, but were slightly enhanced by the deformation.
