Capstone’s Q3 output down on lower grade

Vancouver-based base metals producer Capstone Mining this week reported slightly weaker quarter-on-quarter output, as adverse weather and lower grades at its three mines impacted on its performance. The TSX-listed company, with mines in Canada, the US and Mexico, on Tuesday reported consolidated output of 26 200 t of copper for the three months ended September 30 and 81 500 t of copper in concentrate and cathode in the year-to-date periods, with additional by-products of zinc, molybdenum, lead, silver and gold.
