[{"type":"text","content":" VANCOUVER, British Columbia, April 15, 2019 (GLOBE NEWSWIRE) -- Amerigo Resources Ltd. (\"Amerigo\" or the \"Company\") (TSX: ARG) announces production results for Q1-2019 from Minera Valle Central (\"MVC\"), the Company’s 100% owned operation located near Rancagua, Chile. Q1-2019 production affected by low plant recoveries and maintenance shutdown In Q1-2019, MVC produced 13.0 million pounds of copper at a cash cost of $2.03/lb per pound, and 0.2 million pounds of molybdenum. Production was lower than forecast as a result of low plant recoveries during the quarter. Cauquenes material was extracted from a known poor-quality zone as dictated by the mining plan sequence. However, in addition to lower grades, the material had a higher than expected fines content and significant iron and clay contamination, which negatively affected recoveries and the quality of the final copper and molybdenum concentrates. In addition, MVC suspended operations for an unexpectedly long 7 days in March, in response to a shutdown of Codelco’s División El Teniente (“DET”)’s tailings system, as announced in the Company’s news release of February 28, 2019. The shutdown was required to conduct maintenance work in various sections of the entire DET tailings concrete channel. The ramp up and optimization of MVC’s new flotation plant was affected by the shutdown, the high fines content and the contaminations, requiring frequent adjustments to plant operating conditions.
