The Sindesar Khurd mine lies on the same geological belt as the Rajpura Dariba mine. The mine is approachable from Rajpura Dariba mines by road.

The mineralization has been traced over almost 2.5 kilometers along strike and 1.3 kilometre vertical extension. In the mine area, dip is steep westerly, while the dip turns into easterly direction in the lower-southern part of the deposit. The current mine block extends over 1,500 meters along strike and up to 420 meters depth extension.

The deposit has been drilled to a depth of approximately 1,300 meters below surface and the ore body is traced over approximately 2 kilometers along the strike with a 1,100 meters vertical extension. While the deposit is still open in depth in the southern extension of the present mine block, the area below the mine block and towards the north extension only has narrow and low to moderate grade mineralization intersected.

Mining: Sindesar Khurd has access to the mine through an inclined ramp. Mining method is blast hole open stoping with filling.

The current mine block extends over 1,500 metres along strike and up to 420 metres depth extension.

Ore produced from the mine is treated at 2.0 mmtpa beneficiation plant commissioned in 2011 at Sindesar Khurd. Benefication plant has undergone debottlenecking in January 2015 to increase its capacity from 2 to 2.8 mtpa at Sindesar Khurd.

The ore is crushed at the surface and transported to the beneficiation plant for further crushing; milling; and flotation process. Lead and zinc concentrates are sent to their respective high rate thickeners installed separately for lead concentrate and zinc concentrate generated from the concentrator. Tailing dewatering and disposal section comprises of hydro cyclone, tailing thickener, neutralization tank, pumping of tailing to tailing pond and reclaimed water pumping. Lead and zinc concentrates are thickened, filtered and stored before they are sent to HZL’s smelters.
