Consolidated Zinc Limited (ASX: CZL or “the Company”) is pleased to announce it has executed a new Toll Treatment agreement for its Plomosas Mine, Chihuahua State, Mexico, and is negotiating new offtake agreements for Plomosas concentrates.

On Friday 22 March, CZL received a copy of an email sent to Minera Latin American Zinc S.A.P.I. de C.V. (“MLAZ”), operator of the Plomosas Mine, from the legal representatives of Grupo Mexico, with which the MLAZ has had a toll treatment and offtake agreement in place since September 2018. The email formally notified that the Grupo Mexico Toll Treatment and Offtake Agreement would terminate in 60 days.

On 29 March, MLAZ executed a toll treatment agreement with a well-established toll treatment provider Triturado y Minerales La Piedrera S.A. de CV, who operate the Aldama concentrator facility (the “Aldama Plant”), located close to the Plomosas Mine.

Key details of the new tolling treatment agreement with the Aldama Plant include:

  • Ore processing capacity of up to 300t per day or 9,000t per month
  • Plomosas ore will fully utilise this capacity, with no blending of Plomosas ore with other material

  • Term of 18 months with 6 month extensions at MLAZ election
  • Termination notice period of 6 months by the Aldama Plant, 1 month by MLAZ

  • Plomosas ore will be marketed and sold by MLAZ, and

  • Plomosas ore processing commences on 22 April 2019.

CZL will process Plomosas ore at both the Aldama Plant and Grupo Mexico Santa Eulalia concentrators for approximately a month under its contracts.

Zinc and lead concentrates produced from Plomosas have very low levels of impurities and are within all deleterious impurity limits. The Company is currently in advanced negotiations with a number of parties, including Industrias Penoles S.A.B. de C.V. and Trafigura Beheer BV, to sell the Plomosas Zinc and Lead Concentrates and will provide an update to shareholder’s once these formal offtake agreements have been executed.

ZL Managing Director Brad Marwood said, “The opportunity to replace the Grupo Mexico contract with a longer-term contract with improved conditions has been an opportunity that delivers process certainty for the next 18 months. I am very pleased that our Mexican team have secured this opportunity in such a timely manner.”

The Aldama Plant has operated for over 30 years, with Plomosas ore successfully toll treated through the Aldama Plant prior to the Company acquiring ownership of the Plomosas.

For and on behalf of Consolidated Zinc Limited.

Consolidated Zinc Limited (ASX: CZL) owns 90% of the historic Plomosas Mine, located 120km from Chihuahua City, Chihuahua State, Mexico. Chihuahua State has a strong mining sector with other large base and precious metal projects in operation within the state. Historical mining at Plomosas between 1945 and 1974 extracted over 2 million tonnes of ore grading 22% Zn+Pb and over 80g/t Ag. Only small-scale mining continued to the present day and the mineralised zones remain open at depth and along strike.

The company has recommenced mining at Plomosas and is committed to exploit the potential of the high-grade Zinc, Lead and Silver Mineral Resource through the identification, exploration and exploitation of new zones of mineralisation within and adjacent to the known mineralisation with a view to identify new mineral resources that are exploitable.
