Pan American Silver has reported positive results from ongoing drilling on the recently discovered skarn target at its La Colorada underground mine in Zacatecas, Mexico. More than 11,300 m of infill and step-out drilling were completed during the second quarter of 2019, lifting total meters drilled on the target to more than 31,000. At the end of the quarter, four drill rigs were operating underground and three were operating on surface.
The La Colorada drilling has defined a polymetallic mineralized skarn system starting 300 m below the mine’s current production level. Each drill hole has intersected multiple mineralized horizons and veins with varying widths. Additionally, four drill holes intersected mineralized hydrothermal breccia, a previously unknown mineralizing event.
Over the remainder of 2019, Pan American plans to complete a 50,000-m drill program and review the results of a 12-km magnetotellurics geophysics survey undertaken to better define the skarn footprint limits and the location of higher concentrations of sulphides.
