The program is designed to test the main Chapman structure (a broad, shallow dipping, mineralised thrust zone with thicknesses up to 20 metres) in a complex litho-structural and geochemical setting.

King River’s previous drilling at Chapman had defined a strong thrust zone over a strike of over 800 metres with arsenic-gold mineralisation in most holes.
The company believes that this consistent structure has potential to host a significant gold deposit.
The new deep diamond hole is designed to test the Chapman structure in a new geochemical and litho-structural environment close to a major north-east trending structure.

A deep reverse circulation (RC) hole (220 metres) was drilled prior to positioning the diamond hole to assist with targeting.
The hole intersected the thrust zone with quartz veining and arsenic mineralisation (assays pending) allowing better extrapolation of the thrust at depth.
The new diamond drill hole is designed to a depth of 600 metres and will take about 2 weeks to complete (budgeted drill costs of $130,000).
Meanwhile, RC drilling will continue at Mt Remarkable testing high grade gold epithermal vein targets during October and November.
