NSW Statewide Minerals Resource Audit

Manager - Minerals & Land Use
“Who’s on First?”
Early land use planning around mines and quarries was based on existing use rights and often led to situations where no-one wins in the long run
• Sydney REP 9 (1986, 1995) • Hunter REP (1989) • Illawarra REP 1(1986)
Comprehensive, up to date information on the location of mineral and extractive resources is essential to sound land use planning. Providing such information has been an important role of Mineral Resources since the 1960s.
Why is Geological Survey involved in Land use?
Section 117 (2) Direction 1.3 Mining, Petroleum Production & Extractive Industries
• Purpose is to prevent unnecessary sterilisation of resources due to inappropriate zoning.
• Issued in 1994 - amended 2005 & 2007. • Requires councils to consult T&I if proposed LEPs would
prohibit or restrict development of mineral, petroleum and extractive resources of state and regional significance identified by Trade & Investment.
• If T&I objects to an LEP, council must provide justification for proceeding to Department of Planning & Infrastructure. • “Section 117” mapping program initiated by Mineral Resources Branch to provide councils with resource data.
Notification Status 1998
• NSW Planning Reforms 2004 • SEPP Mining Petroleum Production & Extractive Industries –
requiring councils to consider impacts “in the vicinity of” extractive operations and resources.
• Standard Local Environmental Plans (LEPs) for all Councils by 2011 • 300+ zones into 25 new zones • Resource Audit commenced 2007 to provide data on mineral &
extractive resources to councils to inform new LEPs. • Data will meet requirements of S117 Direction 1.3 & Mining SEPP. • Will update data for LGAs where S117 data previously provided as
well as provide data for those LGAs not previously covered. • To be completed by mid 2011….

Most Identified resource areas were threatened in 2006-7
Martin’s Creek Quarry
Somersby Plateau Southern Potential Sand Resource
Somersby Plateau Northern Potential Sand Resource
1000m blasting 500m non blasting
Types of resource areas
Resource Audit Flowchart: 1. Acquire data and geodatabase 2. Plot data in GIS, allocate some areas 3. Field check where required 4. Assign identified/potential resource areas 5. Write report using template 6. Peer review of shapes and justification 7. Amend GIS and report as required 8. Present report and maps to council

What Next ? • Provided to Dept of Planning & Infrastructure
(DP&I) for input to SRLUP • DP&I to publish SRA on website – under EP&A
legislation • Coal & petroleum resource supplement • Presentations to Councils, planners • Continual updating with new resource areas and
changes in details • Develop online delivery – single point of truth • Adding to metadata – resource estimates,
consent boundaries, deposit models, mine plans, infrastructure, $ values
