Slide 17: In 2006 BHP Billiton said…
In 2006 BHP Billiton said… • We will not proceed with a mining proposal that would have a negative impact on the deep alluvial irrigation aquifers. • We do not expect it to be feasible to mine the whole of the exploration area. Slide 17
Slide 18: Mining methods not being considered
¾Not considering Longwall mining under deep alluvial irrigation aquifer ¾Not considering Longwall mining under the flood plains ¾Not considering Open Cut mining anywhere on the Caroona ELA Slide 18
Slide 19: Targeted Exploration
Targeted Exploration • The Mooki River and Quirindi Creek are outside the area to be targeted for further exploration. • These areas are generally located under the ridge country of Doona Point (including Doona State Forest), Nicholas Ridge and George’s Island. • Exploration drilling to date, and ot
Slide 20: What next?
What next? • Community Consultation • Further slim core drilling • Environmental monitoring – Surface and Groundwater – Air quality – Meterological conditions – Noise – Flora & fauna – Cultural heritage – Soils • Pre-Feasibility (Selection) Phase Study Slide 20
