About us

Kingsley Allen has been involved in the mining industry for 20 years, including the operation of a medium-scale alluvial gold mine in Papua New Guinea, working alongside government bodies developing and implementing community-based mining projects there.

He studied Real Property Valuation at The University of Queensland and spent a number of years working for government in property development, leasing, acquisitions, arbitration and litigation matters. With his background in valuation, finance, investment analysis and related property law, he went on to develop real estate, with a focus on specialised, complex small to medium scale subdivisions.

Kingsley established Great Eastern Gold in 2019 and has led the acquisition and resource development of the portfolio of gold assets the company owns.

He has a hands-on approach to business and in-depth knowledge of gold mining methods, gold resources, exploration and resource development. He is passionate about gold mining production and history, and has used his knowledge of historical sites to help identify the mining tenements the company acquired.

He has a special interest in projects that benefit disadvantaged communities in Australia and overseas, and in developing integrated indigenous businesses that provide a future fund for those communities. He is also committed to bringing the latest decontamination technologies into mine site practice, to shift mining culture from containment to rehabilitation.
