The company put up barriers to contain the spill, neutralized the acid with lime and removed the spilt liquid. In addition, the affected area was neutralized and cleaned, the agency said.

Profepa will visit the area to test for soil contamination and to determine if any remediation work is required.

No-one from the company was immediately available to comment. La Caridad, operated by subsidiary Southern Copper, produced 74.5Mlb copper in Q2, up 4.1% on the same period last year.
