Aug 27, 2012 (A Wilson) - The southern stripped area consists of gently dipping, graded beds of siltstone-quartz clast cobble conglomerate to pebble conglomerate with a sandstone cap. Two obvious graded sequences are present, which vary from 40cm to 1.5m thick. The cobble conglomerate, with clasts up to 15cm, is matrix supported with 50 to 75% clasts of siltstone and quartz (with quartz making up l0-25% of the clasts). Clasts tend to be well-rounded; quartz clasts are spherical to elongate (2:1 length to width) and siltstone clasts are generally elongate (2:1 to 4:1 length to width). The cobble conglomerate grades quickly upward to a pebble conglomerate of the same composition where clasts average 4-5cm to l-2cm in size. Capping the conglomerate is a thin (1 cm to 2cm) layer of quartz sandstone which also makes up the conglomerate matrix. This quartz sandstone is medium to coarse grained and has a whitish cement.

Aug 27, 2012 (A Wilson) - The initial grab sample from the "Southern Occurrence" (sample 60286: 8742 ppb) was from the sandstone matrix of a quartz-siltstone cobble to pebble conglomerate with t-2% pyrite in the matrix (no clasts were present in the initial grab sample). Fifteen out of thirty-eight samples returned assays greater than l00ppb All four of the highest assays were within the quartz sandstone unit but not the entire sandstone unit influenced samples returned high assays which reflect the erratic nature of the gold. Sample 60370 with 2477ppb Au was located across the area where the 0.25oz7T Au samples were taken during the first phase. Samples 60373 (5361ppb Au) and 60227 (573ppb Au) were taken perpendicular to each other in the same location. Sample 60375 (722ppb Au) was taken at the contact of the sandstone unit with the overlying cobble conglomerate.
