Results from this release incorporate drilling from the Martillo and 822-2 underground drill stations which were developed to expand and define mineralization at the Rodilla, NE-1S and 623 Mantos. Drill results in this release were not included in the Company's updated Mineral Resource Estimate as of March 31, 2018 and represents potential for additions to existing resources. Platosa drill core samples are prepared and assayed by SGS Minerals Services in Durango, Mexico. The lab is accredited to ISO/IEC 17025. The Company has a comprehensive QA/QC program, supervised by an independent Qualified Person. Surface drilling continues with a drill rig testing targets that host the Platosa deposit within the north-south trending Platosa corridor, with assays pending. The Company continues to test priority targets within this corridor while defining new targets at Jaboncillo, PDN, Saltillera North and South and San Gilberto through ongoing fieldwork. A 3D induced polarization program was completed at Jaboncillo and PDN in late 2018 in preparation for drilling programs on both targets in the coming months.
