World Uranium Resources
Total identified uranium resources (measured + indicated +
inferred) as of Jan. 2013: 5,902,900 t of uranium metal (increase
of ~11% compared to Jan. 2011)1.
Results mainly from re-evaluations of previously identified
resources and addition to known deposits (Australia, Canada,
Czech Republic, Greenland, Kazakhstan, China and South Africa
due to 23% increase in uranium exploration and mine
development expenditures 2010-2012).
At the 2012 level of uranium requirements, identified uranium
resources are sufficient for over 120 years of supply for the
global nuclear power fleet (world reactor requirements 61,980
tU).

Geological Types of Uranium Deposits2
Uranium occurs in a number of different geological
environments.
Most Kazakh uranium resources are sedimentary.
Most Canadian uranium resources are unconformity-related.
Most Australian uranium resources situated in roll-front,
unconformity-related and Fe-oxide breccia complex ore bodies.

Geological Types of Uranium Deposits3
1. Unconformity-related deposits (e.g. Key Lake, Canada)
2. Sedimentary formations/aquifers overlying and underlying the ore
aquifer being long-term monitored ( results reported to Ministry of
Mining/Environment).
3. Potential use category of groundwaters unchanged.
4. Assessment of potential for impact on fossil groundwater aquifers
above/below the ore zone aquifer.
5. Assessment of liquid waste capacity ( environmental assessment
report prior to mining approval).
6. Remediation strategies (see above).
7. Compliance monitoring (see above).

Excursion Control Parameters
The proposed parameters of:
• pH, SO4, EC (for lateral wells)
and
• pH, SO4 and uranium (for overlying and underlying wells)
are selected because these parameters will exhibit the greatest
contrast between native groundwater and mining solution, whilst
being readily and reliably measured.

Aquifer remediation methods available
If required to meet outcomes
Groundwater flush (creates waste stream)
Pump, treat and re-inject
- Batch treatment
- RO (reverse osmosis) or electrodialysis (creates waste stream)
Mixing
Non-mineralized leaching
Addition of remediation agents
- H2S
- CSIRO’s Virtual Curtain Technology (lime-based additives –hydrotalcites - to remediate acidic and contaminated waste water in one step; e.g. pre-treatment for RO)

ISR Hydrogeology – Current State of Knowledge
1. Current state of knowledge is robust and suitable to
ensure that ISR mining can be undertaken without
unacceptable impacts.
2. Good understanding required of:
ore zone hydrogeology
regional hydrogeological setting
natural attenuation processes
3. Arguably a more robust understanding than for any
approved uranium mine (including Beverley mine).
4. Mining more knowledge enhanced mining and
management practices enhanced (environmentally
sustainable) mine closure.
