In connection with closing of the Transaction, PDI expects to issue an aggregate of approximately 2,115 million PDI Shares to Robex shareholders, based on the Robex Shares outstanding as at the date of this announcement. PDI may also issue up to approximately 497 million additional PDI Shares subject to conversion of any Robex convertible securities into Robex Shares prior to the Effective Time, including up to approximately 281 million PDI Shares from the conversion of Robex’s 32.38 million warrants with an exercise price of C$2.55 per warrant, which recently had the expiry date accelerated to 18 October 2025.⁵

Under the Plan of Arrangement and in accordance with the Agreement, any of Robex’s convertible securities, including its outstanding warrants, options and other incentive securities, which are not exercised prior to the Effective Time will remain outstanding in accordance with their terms and, after the Effective Time, will be exercisable for PDI Shares in lieu of Robex Shares, provided that the number of PDI Shares and exercise price for each PDI Share will each be adjusted based on the Exchange Ratio.

The combined company will be led by a combined board and management team of experienced mining and business leaders, bringing together their respective strengths and capabilities. The Transaction is expected to close in December 2025 or early 2026.

STRATEGIC RATIONALE FOR THE TRANSACTION

PDI’s key asset is the Bankan Project in Guinea, which has estimated average production of approximately 250koz per annum over 12 years,⁷ and is advancing towards a final investment decision targeted for the second quarter of 2026. Robex is currently constructing the Kiniero Project in Guinea, which is on schedule to achieve first gold production in December 2025 and is expected to produce an average of 139koz per annum over 9 years.⁸ Robex also operates the Nampala gold mine (“Nampala Project”) in Mali, which is forecast to produce 46-47koz in 2025.⁹

Key strategic, financial and operational advantages of the combined company include the following:

• Pathway to becoming one of West Africa’s leading gold producers: Combines two of the potentially largest, lowest cost and most advanced gold projects in West Africa, enhancing scale, access to capital, strategic relevance and competitiveness; the combined company is expected to have +400kozpa Au¹⁰ of production by 2029, combined Mineral Resources of approximately 9.5Moz Au¹¹ and combined Ore Reserves of approximately 4.5Moz Au.¹²
• Flexibility through leveraging cash flows from Robex to fund development of the Bankan Project: Significant cash flows expected to be generated from the Kiniero Project and the ongoing exercise of in-the-money warrants and options, which can support development of the Bankan Project.
• Right management and board skill set to drive value creation: Strengthened team with a proven in-country track record and complementary skill set to develop and operate mines in West Africa, and with extensive experience working within dual-listed and large mining companies in Africa. Robex’s leading development team are ready to move from the Kiniero Project’s construction to the Bankan Project’s development, applying lessons learned and optimizing workforce deployment.
• Potential for meaningful upside: Proximity of the Bankan Project and Kiniero Project creates a tier-1 mining hub with potential for meaningful upside, coordinated development, operating and exploration strategies, and enhanced ability to leverage in-country resources.
• Enhanced capital markets presence: Greater scale and multi-asset nature of the combined company, with potential inclusion in the ASX 200 and VanEck Junior Gold Miners (“GDXJ”) indices, enhancing its relevance and attractiveness to investors, positioning it for a potential share price re-rate.

Andrew Pardey, Chief Executive Officer and Managing Director of PDI, commented: “By combining two of West Africa’s largest and most advanced gold development projects and leveraging the proven track record of both management teams in Africa, we are creating a company that positions Guinea to become one of Africa’s top five gold producers. The new, diversified company will not only further de-risk our flagship Bankan Project, but also deliver enduring value for shareholders, the communities where we operate and Guinea as a whole.”

Matthew Wilcox, Chief Executive Officer and Managing Director of Robex, commented: “This combination marks a transformative step for both companies, creating a platform with the scale, assets and capability to deliver long-term value. As incoming CEO and Managing Director of the combined company, I am excited to lead a team that brings together deep operational experience, proven development expertise and a shared commitment to responsible growth in West Africa. I look forward to overseeing the successful commissioning of the Kiniero Project and rapidly advancing the development of the Bankan Project.”
