Pioneer Resources Limited announce the following personnel changes to refresh its senior leadership team and oversee the next phase of development of the Company's multi-commodity asset base. Experienced mining executive Timothy (Tim) Spencer, who has been with Pioneer since October 2017 in the roles of Chief Financial Officer and Company Secretary, will be appointed as Chief Executive Officer, effective 24 January 2020. Mr. Spencer will replace David Crook, who is stepping down after 16 years of service to Pioneer as Managing Director.

Besides his long-standing stewardship of Pioneer since 2003, Mr. Crook's achievements while at the Company's helm have included the discovery of the Mt Jewell gold deposit, which was subsequently sold for A$8 million, the acquisition of the Acra Gold Project, which was subsequently joint ventured with Northern Star Resources, and the discovery and commercial exploitation of the Sinclair pollucite deposit (Sinclair Mine). More recently, Mr. Crook has overseen the discovery of the Pioneer Dome North lithium prospects, which represent a promising growth opportunity for the Company moving forward. Mr. Spencer has over 25 years' experience in the resources and precious metal sectors, including executive roles in the development of two gold mines through to production.

He played a key role in ensuring that the Sinclair Mine delivered both commercially and operationally, and in negotiating the Sinclair off-take transaction with Cabot Specialty Fluids (now Sinomine Specialty Fluids) and the Kangan Gold JV with Novo Resources and Sumitomo. Pioneer also advise that Paul Payne will join the Company's Board as an independent Non-Executive Director, effective 24 January 2020. Mr. Payne is an experienced geologist with a strong technical background, senior executive and board experience.

Mr. Payne was the founding Managing Director of Dacian Gold Limited and is currently a non-executive director of Carnaby Resources Limited and Dreadnought Resources Limited. He will be available to provide technical and mentoring support for the Pioneer exploration team, led by Stuart Kerr.
