In November 2006 Direct Nickel Projects Pty Limited (“DNP”) entered into a process development and licensing agreement with the US-based research and development corporation, Drinkard Metalox Inc (“DMI”). DMI is a recognised world leader in nitrate chemistry and had earlier patented its nitric acid recycle technology which is incorporated into and a key step in the DNi Process™. DNP has exclusive and perpetual worldwide rights to the DMI developed patents and is the owner of the DNi Process™.

DNP has invested over twelve years and almost $40 million in the development of the DNi Process™.

2010   CSIRO makes its first equity investment in DNP and the commercial scale, acid-recycle demonstration is successfully completed at DMI’s facility in Charlotte NC; the licence granted to DNP  is confirmed by DMI as ‘perpetual’.

2012   CSIRO decides to make a further investment in DNP; completion of construction of Stage 1 of Perth Test Plant; Teck Resources confirms approval for funding the Stage 1 Perth Test Plant programme; 200 tonnes of ore from PT Antam’s Indonesian laterite deposit on Halmahera Island arrives in Perth.

2013   Hot commissioning of the Stage 1 Test Plant commenced and completed in February; the first ore from Teck Resources majority owned Santa Fe Ipora mine in Brazil is processed in the Test Plant; official opening of the Perth Test Plant takes place; hot commissioning of the Stage 2 Test Plant (full flowsheet); completion of the planned 19 campaigns of ore through the Test Plant.

2014   Delivery of the Nickel Production Demonstration Program report detailing the successful completion of the 2013 testing.

2017   A Co-Operation Agreement is signed with ANROCA Pty Ltd (trading as Queensland Pacific Minerals) to pursue a project in Australia.
