The final outcomes of the investigation included a 3D geotechnical model showing the distribution and extent of the cemented strata and the geotechnical parameter ranges associated with defined geotechnical units. The model was incorporated into the mine and production planning to optimise operational planning and control.

SRK was appointed to assist with emergency drought intervention programmes in 2016 and 2019. This included the drilling and testing of boreholes for rural water supply. In 2016, 36 villages formed part of the programme. Forty two boreholes were constructed for abstraction purposes at a combined yield of up to 53.55 L/s (4,626 m3/day). Thirteen villages formed part of the 2019 programme and 10 production boreholes were established to deliver a combined yield of 12 L/s (1,036 m3/day). 2 newly defined corridors containing high-grade N copper zones Kamoa North 0 5 10 Western Foreland kilometres exploration licences Kamoa (Ivanhoe Mines 100%) Kansoko Mine Total Copper (%) (2.0% cut-off) Kakula Mine 0 Kamoa Kakula 1 Mining Licence 2 (397.4km2) 3 Kakula West 4 5 Kamoa-Kakula Copper Project 6 Exploration Targets 7 Drill tested area 2% Total Copper grade contours >7 Environmental compliance Platreef 4 Mtpa feasibility study Kakula mine South Africa has a comprehensive In 2015, Ivanplats (Pty) Ltd investigated The Kamoa-Kakula Copper project has governance framework informing the feasibility to develop a new 4 Mtpa been independently ranked as the world’s environmental management compliance underground PGM mine known as the largest, undeveloped, high-grade copper in the mining sector.

In 2015, SRK was appointed by a major mining company to conduct stakeholder mapping of three of its mines in South Africa. The purpose of the assignment was to identify key external and internal stakeholders, ascertain their perceptions and behaviours, and identify measures to strengthen relationships - with the findings informing responsive stakeholder engagement plans. Understanding stakeholder dynamics is key to maintaining a mine’s social license to operate.
