ABSTRACT:Vancouver, British Columbia – Ero Copper Corp. (the “Company”) (TSX: ERO) is pleased to announce the first regional discovery based upon the Company’s targeting exercise incorporating the result of the airborne survey completed in late 2018. The new discovery, named Siriema, is located approximately 1.5 kilometers south of the Vermelhos Mine. To date, copper mineralization at Siriema has been defined by both core drilling (11 holes) and reverse circulation (“RC”) drilling (22 holes) totaling 8,566 meters and has been interpreted as a mineralized zone extending approximately 400 meters in strike-length, approximately 20 to 50 meters in width, and from surface to a depth of approximately 250 meters. The zone is interpreted to contain multiple sub-vertical mineralized lenses and remains open to depth and to the east. While the mineralization encountered to date is predominately disseminated, drilling following downhole electromagnetic (“EM”) anomalies continues to intercept a shallow-plunging east-dipping zone of high-grade massive-sulphide breccia mineralization trending to the north-northwest. Follow-up drilling as well as additional down-hole EM surveys along this massive-sulphide zone remain ongoing.
