The Tasmanian Government will secure the future of Nyrstar's Hobart operations with a $22.5m investment to protect the more than 500 local jobs at one of the State's most significant employers.
Premier Jeremy Rockliff said the support package backs Tasmanian workers and their families.
The funding will be provided through a combination of existing support streams already allocated to the company, including its Electrolytic Cellhouse upgrade, and new support streams.
"We've worked closely with Nyrstar and Trafigura over recent months to secure a path forward, and today we're delivering," Premier Rockliff said.
"This package will help keep the Hobart smelter operating, delivering significant investment in maintenance and upgrades to keep the site strong and safe.
"As part of the agreement, Nyrstar will undertake major investment works at the Hobart site, requiring the engagement of around 200 additional contractors and suppliers.
"We're backing industry, backing Australia's sovereign capability and backing the workers who underpin our State's economy."
It forms part of a broader $135 million national package to support Nyrstar's Australian operations during a nine-month transitional phase.
Minister for Business, Industry and Resources, Eric Abetz, said the support for Nyrstar reflected the strategic importance of Tasmania's minerals processing sector.
"The Hobart site is a key part of Australia's critical minerals supply chain, processing zinc sourced from Rosebery on the West Coast and right across the country," Minister Abetz said.
Nyrstar contributes more than $1.7 billion to the national economy each year, employing around 1,400 people directly and supporting over 6,600 indirect jobs across the country.
