Mirasol Resources published assay results from the second program of drilling and initial cyanide extractable gold tests of the mineralization from the La Curva OceanaGold JV in Santa Cruz province, Argentina.

The second program of diamond core and reverse circulation drilling was completed at the project, totaling 3,228m in 17 holes, said the company in a statement.

Nine samples weighing up to 1kg were assayed via the LeachWELL process. Gold recoveries were received from the SouthWest prospect with 93.9% gold recovery achieved from banded epithermal vein style mineralization and an average 69.5% from mineralization style 2, breccia matrix mineralization.
