The Uruguayan National Environmental Agency has granted an operating licence to Orosur Mining, to dispose of tailings at the new tailings storage facility at its San Gregorio mine in Uruguay.

The firm will carry out the construction of a new tailings storage facility in four phases, each phase requiring continued, staged andenvironmental approval.

The permit is valid for the first phase of tailings disposal.

Orosur Mining chief executive officer David Fowler said, "This licence is an important milestone in the continuing operation of San Gregorio and reflects Orosur’s consistently good environmental performance and community engagement."

The San Gregorio mine has produced ore from several deposits or lodes which is hosted along the San Gregorio Shear which has about 10km of mineralised strike.

All the lode gold deposits are associated with quartz-carbonate boudins along shear structures while the principal alteration assemblage is silica-carbonate-sericite-pyrite-chlorite-epidote.
