The people behind the group.

Nathan Mitchell

Nathan Mitchell has spent his career in the resources and energy sector. He joined the family business in 1989 and took the lead role in 2000, driving a period of rapid growth building Australia's largest private drilling contractor, before steering it to a successful exit in 2008.

Since founding Mitchell Group that same year, Nathan has built one of Australia's most active and diversified resources and energy investment portfolios. He has founded, led and funded dozens of businesses through the full lifecycle — from concept and first capital through to growth, listing and exit. Nathan has held board positions across listed and unlisted companies in Australia, Africa and USA, including as Executive Chairman of Mitchell Services (ASX:MSV).

He is widely recognised as a leader in the sector, known for backing projects at the earliest stages, contributing meaningfully beyond capital, and maintaining conviction through the cycles that deter less patient investors.

Chris Baumann

Chris leads the execution of group strategy and management of Mitchell Group's diverse range of business operations and investments across a team of 900+. He brings deep commercial experience across energy infrastructure, project financing, project development and commodity marketing, alongside significant expertise in corporate finance and investments.

For over a decade, Chris has supported the group across capital raising, project financing, restructuring, takeovers and a wide range of commercial and corporate transactions. Prior to joining Mitchell Group, Chris worked in commodities, facilitating physical trade of bulk commodities between major trading partners in China, the United States and India.

Chris holds a Master of Applied Finance majoring in Corporate Finance and Investment Analysis, and a Bachelor of Business.

Nigel White

Nigel brings extensive legal experience across contract law, resources law, mergers and acquisitions, project financing, restructuring, corporate governance and employment law. He began his career at Feez Ruthning (now Allens Arthur Robinson) and has since worked in both private practice and in-house roles across London and Asia, including seven years with BT Funds Management in Sydney and three and a half years as General Counsel with Fidelity in Asia.

Nigel has strong experience across the resources and energy sectors, including as General Counsel for Mitchell Services (ASX:MSV). A core member of the Mitchell team for over 15 years, he has steered the group through many complex and challenging commercial situations. He is a Fellow of the Governance Institute of Australia.

George Thomas

George Thomas is an experienced Leader and Manager with extensive experience in strategic business growth through providing commercially focused leadership within the mining, mineral exploration and heavy equipment industries. A highly experienced senior manager, George brings deep operational and commercial expertise, with particular strength in Mitchell Group's African businesses.

He began his career in retail and investment banking before moving into corporate accounting across a range of industries. Rod holds a CPA qualification and a Master of Business Administration from the Australian Institute of Business.

Rod has a strong track record leading teams to deliver against operational and productivity targets, and is an effective communicator, building relationships both internally and externally and translating financial information for financial and non-financial audiences alike, from executives through to staff at all levels.

He brings diverse experience across financial performance review and analysis, budgeting and financial reporting, with a proven ability to manage and consolidate multiple business streams for reporting and analysis by key stakeholders.

Rosanna Celesto

Rosanna is an accomplished administrator with over 15 years of experience in executive administration and office management. Prior to joining Mitchell Group, she worked across mid-tier and top-tier global law firms.

For over a decade, Rosanna has been instrumental in providing executive support to Nathan Mitchell and the broader leadership team, across both listed and private environments. Her role extends well beyond traditional executive assistance — she manages the complex dynamics of running a family office operating internationally, and leads teams both within the real assets portfolio and across investee companies. Organised and focused, Rosanna brings the judgement and discretion required to support the principals and executives, and the businesses they back.

Izack Mitchell

Izack Mitchell is an Operations Manager with a strong track record supporting both group and business operations across project delivery, fabrication and workshop operations, and procurement. He brings a practical, hands-on approach to ensuring projects are delivered efficiently and operations run smoothly, in support of broader business objectives.

Izack has developed strong field operations experience through multiple remote site deployments in active mining and exploration environments, giving him a solid understanding of the operational challenges and demands of working in remote, operationally complex settings.

Izack holds a Bachelor of Commerce, underpinning his commercial and analytical approach to operations management.

Will Mitchell

He leads the development of pioneering software and business systems spanning business development and CRM, drilling operations, ERP, safety, and other key workflows, helping to drive innovation and efficiency across the business.
