Translation of last paragraph below.

For his part, the representative of the company Galaxy Lithium Jose Vila Melo said the approval of the Environmental Impact Statement (EIS ) announced that the Secretary of Mining ( Rodolfo Micone ) , is a critical step to finally advance the extraction and use of lithium in the eastern sector of the Salar del Hombre Muerto , in Antofagasta de la Sierra .
" The environmental license to develop the project means that we have permission to make the exploitation of the deposit draft , and is also the condition for the project to be financed with our money , credit or international investors. Because without the DIA could not enable the negotiation rounds , "said Vila Melo to the Union.

In that vein , counsel noted that despite some discussions with potential investors could not advance the project because this document was needed. "The next step will be to develop the mine to explode and start selling internationally mineral or use part here, if there is interest in developing , adding value in Argentina albeit in smaller quantities. Apart from raw material to sell you are talking about a battery factory , research still has to follow , it is very difficult to compete with plants and technology from other countries , "he said .
