<p>Turgis Consulting has been rebranded as Royal HaskoningDHV Mining - to align with the larger parent company RoyalHaskoningDHV (RHDHV). <br> <br> RHDHV Mining (Turgis) continues to offer specialised technical professional consulting services to mining companies and financial institutions across the globe. The company remains privately owned and independent of all manufacturers and equipment suppliers. <br> <br> RHDHV Mining (Turgis) is proudly objective and innovative in its work, and is dedicated to the sustainable development of the mining industry. Founded in 1990 by Alex du Plessis, initial work was focused on assisting mining companies in the design and implementation of hydropower systems, and mining supply companies in developing value-add products and services for mining clients. Turgis has grown steadily over the years, focussing on providing clients with integrated, multi-disciplinary solutions to mining challenges. The company always sought to ensure that its work output was to the highest international standards. During the 1990s, Turgis focussed specifically on nurturing expertise in underground hard-rock mining and more recently expanded its multi-disciplinary service offering with the addition of environmental engineering and mineral processing capabilities, and in addressing all commodities, both in surface and underground mines. <br> <br> In 2008, Turgis merged with a large Dutch infrastructure engineering company, DHV Group BV. In 2012, DHV and Royal Haskoning officially merged and rebranded to form Royal HaskoningDHV (RHDHV). The merger not only expanded the Turgis global footprint but also the expertise that Turgis can make available to its clients, particularly in mining support infrastructure.</p> <h3>Specialties</h3> <p> Feasibility studies, Design, Independent review to small and large, Surface and underground mines, Dynamic Simulation, Hydropower, Asset Valuation, Operational Support, Technical Audits, Detailed Design, Geotechnical Engineering, Financial Modelling </p>
