"...Even though a part of the Forest Reserve Imataca is in the river basin of the Cuyuní, the vice-minister asserted that to protect the vegetal lung guayanés, in that sylvan zone mining activities will not be allowed. " We must be coherent with our environmental policy."

From The American College Dictionary: Sylvan - wooded, woody. Take a look at those Vheadline pics of Las Cristinas posted by Group awhile ago. It certainly looks like we are in the Cuyuni basin. Also, without a doubt, the Las Cristinas site does not fit the aforementioned definition of "sylvan". The adjacent forested areas in the pics could be defined as "off-limits", while the Las Cristinas site could be designated as "approved for mining" when Minamb issues the map.
