Environmental, Social and Governance (ESG)

Ardea and importantly the Original Equipment Manufacturers (OEM) with whom it deals all operate to ensure Environmental, Social and (Corporate) Governance (ESG) considerations are at the forefront of the way in which the Company does business and assesses societal impact. All project designs and work practices are predicated on ensuring the Company minimises greenhouse gas emission per tonne of nickel equivalent production. In doing so, the Company can ensure responsible sourcing of critical mineral supply, through sustainable and ethical production.

To this end, Ardea enlisted the services of Digbee ESG™ which is considered the mining sector’s foremost independent assessment platform for ESG disclosure, to assess and report on Ardea Resources and the Kalgoorlie Nickel Project (KNP).

In 2024, Digbee ESG™ awarded Ardea with an “A” ESG score for Corporate and Kalgoorlie Nickel Project activities
This updated submission from 2022, where Ardea achieved a “BBB” rating, shows that the Company continues to prioritise and improve its operational and reporting requirements across all pillars of ESG
Digbee ESG™ is a reputable independent assessment platform for ESG disclosure in the mining sector which is endorsed by leading global financiers such as BlackRock which integrates ESG practices into its investment processes

On receiving confirmation of Ardea’s overall ESG “A” rating from Digbee’s ESG™ independent assessment team, Mr Andrew Penkethman, Managing Director and CEO of Ardea commented:

“Ardea’s commitment to a transparent ESG strategy, reporting and continuous improvement program is exemplified by our partnership with Digbee ESG™.

The independent team of experts from Digbee ESG™ have identified a noticeable improvement in Ardea’s baseline credentials and we will now incorporate their recommendations in order to assist in further improving our Environmental, Social and Governance programs, which will remain a key focus in the development of our assets, and in upholding the highest levels of business integrity and ethics.

The Board and staff of Ardea note our updated overall ESG award of “A” and acknowledge that this range provides some near-term opportunities for improvement which will be realised as Ardea continues to grow and advance the Kalgoorlie Nickel Project - Goongarrie Hub towards development as a leading source of nickel-cobalt Critical Mineral supply meeting the high ESG standards expected from modern society.”

Environmental

Responsible sourcing of materials, through mechanisms such as mandatory reporting of CO₂ footprints for all batteries sold is essential. Traceability is also being implemented with raw materials used in batteries that must be procured according to OECD guidelines for sustainable sourcing. These important considerations are an essential part of the feasibility study work Ardea is undertaking on the KNP, notably through its FBICRC membership.
Project designs and work practices are based on the Company minimising the project development footprint and CO₂ green-house gas emissions when in production. The proposed flowsheet has been enhanced for CO₂ mitigation in the neutralisation circuit through introducing an Atmospheric Leach (AL) circuit to assist in neutralising the High Pressure Acid Leach (HPAL) discharge. The AL circuit facilitates upgrade of the site acid plant utilisation and allows Ardea to generate its own site power requirements off-grid, without relying on fossil fuel for power generation. Responsible sourcing of materials, through mechanisms such as mandatory reporting of CO₂ footprints for all batteries sold is essential. Traceability is also being implemented with raw materials used in batteries that must be procured according to Organisation for Economic Co-operation and Development (OECD) guidelines for sustainable sourcing.

During the 2023 PFS, a cradle-to-gate Life Cycle Assessment (LCA) of the Goongarrie Hub was completed. Using the KNP Goongarrie Hub’s mass and energy data produced for the 2023 PFS, the expected environmental impacts of Ardea’s nickel and cobalt-containing MHP product have been quantified.

The LCA has also undergone third party review and is published in accordance with ISO 14040/2006 and 14044/2006 standards. The reported KNP Goongarrie Hub climate change impact is expected to be 11.9kg CO₂ eq. per kg nickel in MHP based on Ardea’s Scope 1, 2 and upstream Scope 3 emissions. Ardea’s maiden LCA is deemed relatively low for an HPAL operation primarily due to the use of Mineralised Neutraliser (MN) rather than importing and transporting limestone to neutralise acid waste streams. Ardea’s proposed flowsheet, which includes the generation of on-site electricity from steam generated as a by-product of burning sulphur within the sulphuric acid plant, also contributes to the comparatively low LCA.

Education Fund - Ardea Resources established an education fund to support Indigenous students within the communities that Ardea operates. The Eastern Goldfields Education Grant Program offers funding for a range of activities, including education and sporting opportunities. The grants are available upon application to eligible individuals, associations, charities and not-for-profit organisations. Eastern Goldfields Education Grant is independently administered and managed by Kalgoorlie local business, Kalsec. For more information, call (08) 9021 4555 or go to the website.

Kalgoorlie student Noah Hinkley received funding support to help his dream of education and basketball in the USA in 2021. The Goldfields Education Grant Program assisted Noah in funding his 12-month adventure to the USA, attending Community College as well as further developing his basketball talent in an elite program.

Ardea sponsored Leonora Drug Action Group basketball team’s participation in regional tournament, covering team uniform, and travelling funds.

Other local community support initiatives are being considered and will be implemented in the future. For more information visit: www.easterngoldfieldsgrants.com
Ardea enjoys strong support from the communities in which we operate, primarily the City of Kalgoorlie-Boulder and the Shire of Menzies in addition to the local business community.
