Jun 26, 2013 (A Wilson) - The hole encountered 58.8 m of overburden before collaring in quartz-feldspar porphyry. The porphyry was intersected to 134.7 m where the hole passed into talc-chlorite schist exhibiting well-developed spinifex texture. Diorite was encountered from 236.9m to 246.7 m, from 251.0 m to 254.7 m, and 351.2 m to 353.6 m. A partially-developed green-grey carbonate alteration zone was intersected between 313.6 m and 361.0 m. The hole ended in relatively unaltered talc-chlorite schist.
