WINNING While well hidden from traffic and neighbours, the pit is vast. SHAKING UP MIDRAND By Eamonn Ryan On average 175 000 vehicles pass daily within sight of AfriSam’s Jukskei Quarry, which is one of the busiest sections of freeway in the entire country; few people spare a glance at the massive granite quarry as seven lanes from three highways converge into four 18_QUARRY SA| JANUARY/FEBRUARY 2019 B ecause of its location (close to the convergence of the M1, N3 and N1 highways), AfriSam’s Jukskei Quarry is one of the busiest plants in the AfriSam group. At the helm, keeping it running and meeting customer demand, is AfriSam works manager, Daneel Celliers. While many quarries are today located in built up areas, few are quite as built up as Jukskei Quarry’s neighbourhood. Looming over its periphery fence, are the Midrand offices of several major JSE-listed companies. It wasn’t like that when Jukskei started operations over 65 years ago, and Midrand scarcely existed. The mine was established early in the 1950s and the surrounding areas only later started to develop around the mine. The mine is extremely well situated near the fast-developing nodes of Midrand, Sandton and Fourways. It is one of only a few well-established commercial aggregate supply quarries in the area.
