Ardea Resources Limited (Ardea or the Company) is pleased to report an independent panel of globally recognised Environmental, Social and Governance (ESG) experts from Digbee ESGTM (Digbee) have awarded Ardea an overall ESG rating of 'BBB' on both corporate and the Kalgoorlie Nickel Project (KNP or the Project). For an emergent development company such as Ardea, BBB is a meritorious outcome and an excellent platform to achieve AAA as the company grows. In assessing ESG credentials Digbee looked at several factors and awarded those individual factors a score that ranged from CC to AAA. The BBB score achieved by Ardea is an average of all scores and Ardea acknowledges that there is the potential to reflect CC or AAA depending on action or inaction taken to manage ESG risks and opportunities. The top 5 rating bands of AAA to BB (see Figure 1) give credit for present positives/opportunities whereas the bottom 5 rating bands (B to D) reflect present negatives/threats. This review by Digby, demonstrates Ardea's continued strong commitment to ESG integration, reporting transparency and continuous improvement.

Ardea is focused on establishing a sustainable business that is a significant contributor to a de-carbonised future helping to solve complex global problems:

Supply global customers with an alternative, sustainable supply of nickelcobalt and other Critical Minerals essential to driving a Net-Zero Carbon future.

Use sustainable mining practices notably site land rehabilitation; and

Maintain high business integrity, ethics and transparency.

The Digbee platform offers companies a right-sized, future-looking set of globally aligned ESG frameworks to map out ESG risks and opportunities

On receiving confirmation of Ardea's overall ESG 'BBB' rating from Digbee's ESGTM independent assessment team, Mr Andrew Penkethman, Managing Director and CEO of Ardea commented: 'Our commitment to a transparent ESG strategy, reporting and continuous improvement program is exemplified by our partnership with Digbee ESGTM. Now that the independent team of experts from Digbee ESGTM have identified Ardea's baseline credentials, we will now incorporate all their recommendations in order to assist in 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 maiden overall ESG award of 'BBB' and acknowledge that this range provides some near-term opportunities for improvement which will be realised, as Ardea continues to grow and advance the KNP Goongarrie Hub towards development as a leading source of sustainable and ethical nickel-cobalt battery mineral supply. As the improvements are embedded in our current operations, we look forward to preparing our next submission and demonstrating continuous improvement. 'In the coming months we look forward to releasing our ESG strategy and reporting aspirations as we look to embed the improvements outlined in our maiden Digbee report. Ardea's next submission to Digbee for review by the global panel of independent ESG experts is September 2023.' Commenting on the assessment, Mr Jamie Strauss, the founder and CEO of Digbee commented. 'The leadership team of Ardea has shown, throughout their submission, clear incorporation of ESG principles and sustainability priorities as part of the Company's vision and value. This early stage embracement of ESG, the commitment to minimise greenhouse gas emissions per tonne of nickel equivalent produced and the transparency to address areas of remediation identified in the Report, demonstrates a positive culture towards delivering a mine of the future.'

Assessment Findings

The Digbee report and associated scoring system provides Ardea with a baseline of ESG risks and opportunities assessment within the rating credentials for both Ardea corporate (Figure 2) and the KNP (Figure 3). This report will now allow Ardea to apply improvement mechanisms in relation to the pillars of Environmental, Social and Corporate Governance embedded within our entire operation

About Ardea Resources

Ardea Resources (ASX:ARL) is an ASX-listed nickel resources company, with a large portfolio of 100%-controlled West Australian-based projects, focussed on: * Development of the Kalgoorlie Nickel Project (KNP) and its sub-set the Goongarrie Hub, a globally significant series of nickel-cobalt and Critical Mineral deposits which host the largest nickel-cobalt resource in the developed World at 830Mt at 0.71% nickel and 0.046% cobalt for 5.9Mt of contained nickel and 380kt of contained cobalt (Ardea ASX releases 15 February, 16 June 2021), located in a jurisdiction with exemplary Environmental Social and Governance (ESG) credentials, notably environment. * Advanced-stage exploration at compelling nickel sulphide targets, such as Emu Lake, and Critical Minerals targets including scandium and Rare Earth Elements throughout the KNP Eastern Goldfields world-class nickelgold province, with all exploration targets complementing the KNP nickel development strategy. Ardea's KNP development with its 5.9 million tonnes of contained nickel is the foundation of the Company, with the nickel sulphide exploration, such as Emu Lake, as an evolving contribution to Ardea's building of a green, forwardfacing integrated nickel company. Put simply, in the Lithium Ion Battery (LIB) sector, the Electric Vehicle and Energy Storage System battery customers demand an ESG-compliant, sustainable, and ethical supply chain for nickel and other inputs. In the wet tropics, with their signature HPAL submarine tailings disposal and rain forest habitat destruction, an acceptable ESG regime is problematic. In contrast, the world-class semi-arid, temperate KNP Great Western Woodlands with its benign environmental setting is likely the single greatest asset of the KNP. The KNP is located in a well-established mining jurisdiction with absolute geopolitical acceptance and none of the landuse and societal conflicts that commonly characterise nickel laterite proposals elsewhere. All KNP Goongarrie Hub production tenure is on granted Mining Leases with Native Title Agreement in place
