Newfield and the Tongo Mine Development
In early 2018, Newfield Resources Limited (Newfield), an ASX-listed company, acquired Stellar Diamonds plc, a company listed on the London Stock Exchange (AIM). The key shareholders of Newfield have wide ranging business interests including property development, pharmaceutical, building materials and education.
