eis approval process comparo with exs, page-5

I see another potentail problen for CDU included in the EIS for Exco comments !

I think this is why Wayne wanted Wilgar left till after the 10 year 3mt p/a M.L was approved for Las Min !

Conix may have to wait some time to find out wahts going on down in the south west !

Radioactive mineral assessment

The Cloncurry Region is naturally high in mineralised uranium and other radioactive elements. The Exco proposal refers to potential recovery of uranium elements should there be a change in government polity The submitted EIS provides no assessment of the potential impacts on water, ecological and air values from radioactive elements that may be extracted with the ore or waste rock.

The EM plan is required to include an assessment of the potential impacts on water, ecological and air values
from extracting, processing and disposing of radioactive elements, and should propose appropriate mitigation measures for all potential impacts.

To address the potential presence of radioactive (or radiogenic) minerals, Exco resources is required to prepare
a radioactive mineral assessment proposal that includes
-------------------------------------------------------
The analysis has not taken into account all metals, including selenium, strontium, uranium, rubidium, and
lithium.

The submitted EIS does not adequately address the potential leaching of a variety of contaminants under a
representative range of physical and chemical conditions likely to be accounted at the site. Therefore, the proposed waste rock dump design has the potential to place high risk material (such as mineralised rock) on the outside of the dump. The placement of this material on the outside of the waste rock dump is a risk that has not been identified or assessed in the submitted EIS.

Consequently, the methodology for characterising the waste rock does not adequately represent field conditions, nor does it enable a complete assessment against guidelines values.

To address the DERM�s concerns on neutral mine drainage, Exco Resources is required to develop and implement a neutral mine drainage proposal to assess: the potential for release of contaminants from waste rock stockpiles under neutral conditions; the possible impacts of such release; and the management systems required to avoid or minimise those impacts. DERM considers that the Global Acid Rock Drainage Guide(GARD guide) prepared by the International Network for Acid Prevention (INAP) provides appropriate direction for the management of drainage issues from mine waste rock.
