Consolidated Zinc announced operating results for the month of December 2018. The toll treatment has progressed well with recoveries of 89% of Zinc achieved through the Santa Eulalia concentrator. Ore hauled to surface of 4,072 tonnes with improved availability of equipment and more equipment brought to site . This includes the 600t hauled from Level 6 stopes where ore has previously been broken. The grades are impacted by development headings on ore providing a significant portion of ore hauled to the surface. On Level 6 a stoping area has been assayed and found to contain high grade ore blasted but not mined exceeding 3,000t. Lifting of this ore to the surface during the month commenced after the Level 6 Stope access was established for haul trucks with 600t lifted to the surface during the month.

During January 2019 production is expected to increase as the mine will not have the closure and reduced staffing that occurred during the end of year holiday season.
