The Rampura Agucha is a sediment-hosted zinc deposit which lies within gneisses and schists of the Precambrian Mangalwar Complex. The main ore body is approximately 1.5 kilometres long and has a width ranging from five metres to 120 metres with an average of approximately 58 metres. It extends from the surface with recent exploration intersecting up to 15 metre wide mineralised zones at depths of over 900 metres. The southern boundary of the ore body is sharp and steeply dipping while the northern margin is characterised by a thinning mineralised zone. Grades remain relatively consistent with depth. The ore body consists of sphalerite and galena, with localised concentrations of pyrite, arsenopyrite, pyrrhotite and tetrahedrite-tennantite.

The mine is highly mechanized with state of the art technology. Underground Mining is carried out using Long Hole Open Stoping with Paste Fill method with mined out stopes backfilled with cemented rock & with cemented tailing in paste form.

Rampura Agucha open pit mine, which was commissioned on March 25 1991, delivered its final ore on March 25 2018.

The processing facility is a conventional crushing, milling and differential lead-zinc floatation plant. Ore from the open-pit is crushed in a series of crushing circuits and then milled in four streams, one rod mill-ball and three other sag mill-balls in closed circuit. The milled ore is then sent to the lead flotation circuit which includes roughing, scavenging and three stages of cleaning. The lead concentrates are thickened and filtered ahead of storage and transport to the Chanderiya and Dariba lead smelter. The lead flotation tails proceed to zinc flotation which comprises roughing, scavenging and four stages of cleaning. Zinc concentrates are thickened and filtered ahead of storage and transported to different HZL zinc smelters. Zinc flotation tails are thickened ahead of disposal to the tailings dam.

The capacity of the mine and concentrator was expanded between 2003 and 2010 from 2.4 million tpa to 6.2 million tpa for mine and 6.5 million tpa for mill.
