The Nuckulla Hill gold and silver project is located approximately 115 km north-east of Ceduna in South Australia, and covers approximately 60 km of strike of the mineralised Yarlbrinda Shear Zone, approximately 35 km south of Tunkillia (0.8M oz Au, 1.6M oz Ag). The project consists of seven exploration licences covering 2050 square km. Portions of both EL 4473 and EL 5295 have been relinquished as part Doray’s plan to lessen both its land holdings and expenditure commitment in the project area, as these pieces of ground are now considered to have diminished prospectivity for gold and silver. Generally, though, the Nuckulla Hill tenements remain highly prospective, given their location within the Yarlbrinda Shear Zone, along strike from Tunkillia. The exploration history of the project region has been sporadic, and virtually no systematic gold exploration has been carried out since 1997. Despite the recent increase in the gold (and silver) price, the region remains significantly under-explored. Reconnaissance geological mapping done by Doray across both subject tenements encountered widespread broad outcrops of Hiltaba Suite granite. In both reconnaissance and historic sampling, the granites have shown little to no prospectively for gold mineralisation. In areas with colluvium cover (abundant on EL 5295) fine fraction soil sampling was implemented to test for gold anomalism. No significant anomalism was identified. Reconnaissance rock chip and calcrete sampling was also conducted with no significant anomalism identified. In areas with thin sand dune cover, fine fraction soil sampling was trialled with no significant anomalism detected. A total of 390 minus 75 micron sieved soil and 2 grab rock chip samples were collected by Doray on the relinquished ground portions and were assayed for a range of pathfinder metallic trace elements; the geochemical data for these samples is presented herein. The soil samples targeted three separate structures where earlier calcrete sampling had returned low level anomalous (2-3 times background) results. Sampling was carried out at 100 m intervals along east-west traverses having a north-south spacing varying between 200 and 600 m. During rock chip sampling along traverses crossing the southern part of EL 4473, several outcrops of north-south sheared granitoid were discovered. Two distinct sets of foliations were observed in some outcrops, one striking at approximately 010 [degrees True] and a second at about 045. This is in agreement with the two orientations of magnetic structures that Doray sees in aeromagnetic images of this area.
