The last bit about Crystalex being the company to do the mining is very clear. I do not speak/read Spanish but the sentence in the article stands out even in it's native format.

"Consultado sobre las empresas que estarían operando en el Caura, el parlamentario mencionó a la empresa transnacional Cristalex, pero sin ofrecer mayores detalles"

I am wondering how credible this source is?

Along with some of the info contained in KRY's annual report I am more hopeful now of an imminent break through than any time in the last year.

GLTA!
