Media Release

Queensland Government and Rio Tinto partnership to support

Gladstone’s Boyne Smelters

15 August 2024

MELBOURNE, Australia--(BUSINESS WIRE)-- The Queensland Government and Rio Tinto will work

together to safeguard a pillar of the State’s heavy industrial manufacturing base around Gladstone

under a partnership to support investment in renewable energy projects.

The agreement announced today represents an important step towards securing a long-term future for

Australia's second-largest aluminium smelter, Boyne Smelters Limited (BSL) and thousands of jobs in

central Queensland supported by the operations.

The partnership supports Queensland's vision to establish Gladstone as a renewable energy hub and

strengthens the electricity grid as Australia transitions to a cleaner energy future. The cooperation

between Rio Tinto and the Queensland Government will complement ongoing policy development by

the Australian Government to support a decarbonised aluminium industry as part of its Future Made in

Australia Plan.

Highlights of the agreement between the Queensland Government and Rio Tinto include:

•Economic Support: Through its “Energy and Jobs Plan’, the Queensland Government will

support BSL’s financial viability from 2029 as the smelter transitions to renewable energy.

•Operational Commitments & Employment: Rio Tinto will invest to maintain BSL's full

operational capacity, supporting Australia’s ambition to remain a major exporter of aluminium.

This ensures BSL, which has an annual production capacity of more than 500,000 tonnes of

aluminium and directly employs more than 1000 people, will continue to be a significant

contributor to the local, Queensland and national economy. Rio Tinto will also work to expand its

coastal shipping capacity, to add a fifth domestically crewed vessel to its existing fleet of four.

These ships transport bauxite from the company's Gove and Weipa mines to operations in

Gladstone.

•Renewable Energy Investment: Rio Tinto commits to additional sustainable energy

investments in Queensland, building on its existing commitments to Australia's largest solar and

wind projects across the State.

•Gladstone Transformation: Support for Queensland's vision to establish Gladstone as a

renewable energy hub, with BSL to develop capabilities to manage power consumption during

times of peak demand and strengthen the electricity grid.

The agreement remains contingent on the completion of Rio Tinto's energy contracting activities,

relevant joint venture approvals, and the establishment of an Australian Government pathway for a

decarbonised aluminium industry.

Rio Tinto Chief Executive Australia Kellie Parker said: "This agreement with the Queensland

Government represents one of the most significant partnerships in our long history of operations in the

State.

“It paves the way for a competitive, green-energy powered BSL, supporting employment and lowering

Australia’s carbon footprint. The partnership will support Australia’s status as a leading, global supplier

of aluminium at a time when the world needs the metal for the green energy transition.

“While this is a critical part of the puzzle, we have more to do. We will continue to engage with the

Federal Government on supportive industry policy to help sustain Australia’s green aluminium sector for

the future."

About Rio Tinto and Boyne Smelters Limited

Boyne Smelters Limited (BSL) has been operating since 1982 and is Australia’s second largest

aluminium smelter. Located at Boyne Island in central Queensland, BSL’s activities include

manufacturing carbon anodes in the carbon plant, aluminium production (smelting) in reduction lines,

and casting of molten metal into aluminium products ready to ship. The smelter is adjacent to, and

connected via a conveyor belt, to the Queensland Alumina Limited refinery for the supply of alumina.

Rio Tinto's integrated aluminium production chain in Queensland is a significant economic driver,

employing over 4500 people directly and supporting thousands more Australian livelihoods. The

company's operations in Gladstone alone account for more than 3000 jobs, with 1000 of those at the

BSL. Additionally, Rio Tinto's bauxite operations in Weipa employ more than 1300 people, supplying

raw materials to the Gladstone manufacturing facilities.
