ISR Mine MethodIN SITU RECOVERY (ISR) MINING
* Nearly all uranium mining in the USA is by this method;
* Nearly all uranium mining in Central Asia is by this method;
* In 2011, 45 % of all World uranium production was produced by this method.

The In-Situ Recovery Mining Process
Uranerz plans to use the low cost mining process of in-situ recovery mining, a process that uses a 'leaching' solution to extract uranium from sandstone uranium deposits. The 'leaching' agent, which contains an oxidant such as oxygen with sodium bicarbonate (commonly known as baking soda), is added to the native groundwater and injected through wells into the ore body in a confined aquifer to dissolve the uranium. This solution is then pumped via other wells to the surface for processing -- resulting in a cost-efficient and environmentally friendly mining process.
In Situ Recovery (ISR) Mining
+ Low Capital Costs for Mine Development
+ Environmentally Friendly
+ No Waste Rock, No Tailings Pond
+ Profitable on Lower Grade Uranium Deposits
+ Small Work Force (low labor costs)
