Danie has more than 35 years' success driving comprehensive strategic planning, project governance, business analysis, tender/bid development, and general management for renowned, world-class organizations, all aimed at cultivating business and revenue growth and optimal performance. He has been involved in the mining industry specifically from 2003 onwards. While consulting to re-establish a diamond and a coal mine in eSwatini (Swaziland), he initiated the eSwatini 'Mining Rights' Project with a potential market capitalization in excess of US$1 billion. Danie was employed on a contract basis between 2007 and 2009, at RSV ENCO as Project Management Office Manager (PMO), where he was instrumental in the establishment of major engineering, procurement, commissioning, and management (EPCM) coal mining projects such as Thubelisha and Impumelelo at Sasol Secunda. He also spearheaded key efforts to implement an innovative documentation management systems (DMS) and a new PMO system (using PRISM Management Suite and ProjectWise software packages) to effectively support the delivery of cutting-edge EPCM mining projects with values of over R5 billion. He spent the period from 2010 to 2012 in the IT industry, where he was instrumental in compiling numerous tenders and initiating projects worth over R2 billion. He returned to his home ground of engineering project development and management in 2012, and played an integral role in assisting the companies he worked with in pioneering 93 project portfolio concept business plans, about 35% of which are mining-related, to be executed on a global scale with a value of over US$20 billion if implemented.
