Pingandy Creek Project
The Pingandy Creek Project encompasses a regional base metals and uranium geochemical anomaly. A series of shallow drill holes were completed by Pasminco in the 1990s that extend over 30km of strike. The drilling intersected a sphalerite and chalcopyrite mineralised sequence at the base of the Jillawarra Formation and returned up to 3m @ 1.25% Zn (including 1m @ 2.88% Zn).
The targeted horizon hosts a 9km long uranium channel radiometric anomaly and coincident GSWA regional, multi-element (U-As-Mo-Sb) stream sediment anomaly within the Pingandy Project. Downhole gamma logs of two of the percussion holes drilled by Pasminco indicate highly anomalous radiometric responses of over ten times background associated with significant Zn, Cu, AS, Mo an Ni anomalism. Base metal anomalism is found within the alteration halo of a number of unconformity uranium deposits and the coincident radiometric anomalism at Pingandy Creek is considered to be highly encouraging. No uranium analysis was completed on the historic RC drill holes.
Encounter has commenced a program to test the effectiveness of Hyperspectral mapping in the Bangemall terrain. Hypersprectal imaging utilises multi channel spectral mapping to identify mineral and alteration assemblages that can be used to define areas of mineral prospectivity. In order to calibrate the interpretation, hyperspectral data from the Ranger, Narbelek and Rum Jungle uranium deposits in the Northern Territory was acquired and interpreted to identify the style of alteration seen in unconformity uranium deposits.
