Australian Gold Reagents (AGR) is poised to expand its sodium cyanide production to
support growing global demand for gold.

24 FEBRUARY 2022

A significant expansion of AGR’s sodium cyanide plant is being planned for construction in
Kwinana, Western Australia.

If approved, it will increase AGR’s production capacity by circa 30,000 tonnes per annum
from its existing production of more than 90,000 tonnes per annum, with the sodium cyanide
to be used in gold mining operations across Australia, Asia, South Africa, the Americas and
the Middle East.

AGR General Manager Barney Jones said he was excited about the potential to become the
third largest sodium cyanide producer in the world for gold mining.

“The expansion will consolidate AGR’s position as a high-quality supplier with a strong
commitment to innovation, safety, and the environment,” Mr Jones said.

“By applying the experience, expertise and safety credentials we have amassed over almost
35 years of operation, we will be able to capitalise on the efficiency and safety benefits that
come from expanding on an existing industrial site.

“We have an established, high-calibre and well-trained team already in place who can bring
the project to fruition once we complete the necessary studies,” he said.

To progress the expansion, AGR has completed project feasibility and front end engineering
and design studies to explore the project options in more detail, including possible timings
and implementation schedules. Further engineering work is underway to refine the preferred
option.

Depending on the findings of the study, the planned expansion may occur in full or in phases
over a period of years, with all decisions to be underpinned by operational parameters and
the status of the global gold market.

The expansion is expected to deliver improved sustainability at the site through:

• Efficiencies: By utilising the existing site, the expanded plant will connect into
  established infrastructure, delivering capital cost and operational efficiencies and safety
  benefits.
• Low risk: Wherever possible and practical, new equipment will match current plant
  design to reduce risk and enable maintenance efficiencies.
• Water recycling: More than 80 per cent of waste water produced in the manufacturing
  process is expected to be recycled and used in the cooling towers of the expanded
  plant.
• Carbon emissions reductions: The proposed incinerator will lower emissions intensity
  compared to existing operations. Additionally the heat generated will be recovered to
  generate electricity.

The proposed sodium cyanide plant expansion at Kwinana, Western Australia, is the next
step forward in AGR’s journey.

Approval to commence the expansion will be sought in the second half 2022
