In the article it says
"que le permitir extraer entre 600 a 800 mil onzas de oro y ms de 10 millones de onzas de plata en los prximos 7 aos."

To me that says allowing the extraction of between 600 to 800 thousand ounces of gold and more than 10 million ounces of silver in the next 7 years

Using the google translater it comes up with about the same.
