Challenges for
greenfields

exploration


Difficulties in raising funds for
greenfields

exploration


Rising costs of discovery, especially in
Australia


High
-
risk nature of undercover
exploration


Role of Government is to lower the risk
and cost of discovery relative to other
jurisdictions



NT Government support for exploration

Ongoing geoscience programs to attract and support
exploration


Large
-
scale regional geophysical survey


Geoscience mapping programs to highlight
prospectivity


Improved online access to NTGS data and reports and
exploration company reports


Collaborative funding of
greenfields

exploration


Funding 100% up to $100k of selected projects


Round 6 of Geophysics and Drilling Collaborations underway


Assistance for explorers in attracting investment


International investment attraction in key markets such as
China, Japan and Korea


NTGS activities in greater Katherine region

Summary


The greater Katherine region has potential for significant mining developments for
commodities including iron ore,
ilmenite
, zinc, rare earths, gold and diamonds


Gas exploration and development is emerging as a major industry


Exploration industry is experiencing difficulties globally


NT Geological Survey is working to stimulate exploration in the region through
the CORE initiative
