From Dialogue to Delivery: Bridging the Execution Gap

As demand for critical minerals accelerates, the gap between ambition and delivery continues to widen. Projects remain slow to advance, often taking decades due to regulatory complexity, capital discipline, and operational constraints. The industry is being pushed to move beyond planning and into execution that delivers tangible outcomes.

The speakers in this podcast are:

• Darryn Quayle: Vice President, Mining for Worley
• Terry Briggs: Chief Development Officer for Anglo Gold Ashanti
• Christopher Vandome: Senior Research Fellow, Global Economy and Finance Programme and Africa Programme; Lead, Critical Minerals Initiative, Chatham House
• Assheton Stewart Carter: Executive Chair, TDi Sustainability (Host)

The speakers argue that the execution gap is systemic rather than technical, emphasising that feasibility studies must be designed to build mines rather than simply raise capital, that execution expertise and affected stakeholders should be involved at concept stage, and that projects must be aligned with corporate, national and local priorities.

This episode is part of the TDi Sustainability special series of podcasts produced in advance of the Resourcing Tomorrow 2026 event that will take place in London between 1-3 December. Find out more about the event here.
