Annual report on EL 24841 Murphy project 1 August 2009 to 31 July 2010

Abstract

Work during this period comprised: geological mapping; geological interpretation of the 2008 detailed airborne magnetic, and radiometric survey; 3D inversion modeling; target generation; and three RC / diamond drill holes were drilled for 1062.7m. Two new targets, UC25 and UC26 were defined by Doug Haynes and the target areas for UC19, UC 22 and 23 were altered based on the new interpretation. Seven addition base metal (Cu-Ni) targets were defined. 3D inversion modeling of the detailed airborne magnetic data help determine depths to magnetic targets and the geometry of the magnetic, and possible mafic, geology at UC19 and Camp target areas. Ground magnetics at UC19 were useful in mapping the magnetic bodies and structural zones; however, the presences of maghemite in the regolith resulted in very noisy data which reduced the effectiveness of this geophysical method. Two RC/Diamond tailed holes (MURD015 and MURD016) were drilled to test for extensions to the mineralisation intersected in MURD002, within the altered mafic dyke; and also test for mineralisation in an interpreted mafic dyke adjacent to the NW trending fault. MURD015 intersected the upper mafic dyke and lower non-magnetic dyke. However, the assays returned only elevated U and Cu values in the lower dyke. MURD016 remained in unaltered sandstones of the Westmoreland Conglomerate and failed to intersect the inferred mafic body or basement lithologies. One RC/Diamond tailed hole (MURD013) was drilled to test the depth of the Phanerozoic cover rocks, the unconformity between the Westmoreland conglomerate and the Murphy inlier and to determine whether the lithologies in the Murphy inlier are favourable for uranium mineralisation. The hole was also designed to test a magnetic body which turned out to be a barren dolerite. No significant geochemistry was located.
