Nyrstar enters into option agreement to sell Coricancha mine

19 May 2015

Nyrstar ("Nyrstar" or the "Company") today announces that it has reached a two-year option agreement to sell its Coricancha mining complex ("Coricancha"), located 90 kilometers east of Lima, Peru, to Great Panther Silver Limited ("Great Panther") – a Canadian precious metals mining and exploration company with operations in Latin America.

The terms of the option agreement call for Great Panther to make a cash payment of USD 1.5 million upon signing. A second option payment of USD 1.5 million is due on the first anniversary of signing to extend the option for a second year. Should Great Panther exercise the option on or before the second anniversary, the companies would enter into a Share Purchase Agreement whereupon Great Panther would make a cash payment of USD 5 million for 100 percent of the shares of Nyrstar Coricancha, S.A. (plus the second option payment if not already paid).

There is a further contingent payment of USD 4 million payable to Nyrstar under certain conditions.

Under the option agreement, Great Panther will undertake certain exploration activities during the two-year option period of USD 2 million in the first year and USD 3 million in the second year.

Coricancha was acquired by Nyrstar in October 2009. It has been on Care and Maintenance since August 2013. The mining complex consists of a poly-metallic underground mine with more than 60 years of operating history and a 600-tonne per day ore processing facility. Reserves and resources include gold, silver, zinc, lead and copper.
