Consistent strong sericite altered monzodiorite hosting disseminated arsenopyrite-pyrite (gold-bearing) mineralisation was observed from where the drill hole entered the pipe, at approximately 336m down hole, through to where the hole intersected a more mafic diorite at a down hole depth of 890 to 920m (at pipe edge).

In places quartz and pyrite may dominate along with fine-grained sericite.
Kris Butera, CEO of Gossan Hill Gold (SOC owns 87%), stated, "We are delighted that the current hole has demonstrated a minimum approximate true width of 100m at depth, and widening, and consistently strong sericite alteration and sulphide mineralisation from where the hole entered the pipe at 336m to the current depth.

Sonic drill hole RS12-06 returned values from background up to 157 ppb Au, and is situated within a 700 metre by 400 metre gold, molybdenum and arsenic soil geochemical anomaly, in an area where strongly sericite altered felsic volcanic rocks and siliceous exhalites have been mapped at surface (please see Strongbow news release #12-06 dated July 26th, 2012).
