"Cube Consulting and CSA Global to undertake an independent resource estimation and preliminary economic mining study for the Project."
I'd guess one is doing resource estimation and the other is doing preliminary economic mining study. At a guess.
"The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (‘the JORC Code’) is a professional code of practice that sets minimum standards for Public Reporting of minerals Exploration Results, Mineral Resources and Ore Reserves."
"The JORC Code was first published in 1989, with the most recent revision being published late in 2012. Since 1989 and 1992 respectively, it has been incorporated in the Listing Rules of the Australian and New Zealand Stock Exchanges, making compliance mandatory for listing public companies in Australia and New Zealand."
JORC is Aus/NZ standard not related to South Africa.
