It placed 15.4 million new shares with institutional investors at €6.50 per share, with the new shares representing 16.4% of the number of outstanding shares before the transaction.
The deal is supposed to close on November 17 when Nyrstar shares will total 109 million.
Of the total proceeds, €30 million will be used to restart Myra Falls in British Columbia, which was suspended in October 2015.
The remainder will fund the €70 million capital investment required to finish the redevelopment of Port Pirie in South Australia, which is being ramped up and should result in "a substantial earnings uplift from 2018 onwards".
The redevelopment includes replacing the old sinter plant with an oxygen enriched bath smelting furnace, replacing the old sulphuric acid plant with a new plant with greater capacity and upgrading technology at the smelter.
