Located in the Bhilwara district of Rajasthan state, RAM is the largest and richest, lead-zinc deposit in the country and among the world's largest with 75.0 Mt of ore reserves and resources (R&R) with in situ average grade of 10.8% zinc and 2.0% lead on an exclusive basis as on end of FY 2021-22.

By perfect concentration, assuming the lead to be as galena and the zinc as sphalerite: The value of crude ore by perfect concentration is then $11.46 for the lead concentrate and $11.18 for the zinc, or a total of $22.64 per ton of crude ore. By formula (28) Economic recovery = 100 x 18.50/22.64 = 81.7%

NEWFOUNDLAND – Canadian Zinc Corp. of Vancouver and Buchans Minerals Corp. of Toronto have been exploring the concept of a centralized mill to process ore from five base metal deposits in the central part of the province. Both companies have volcanogenic massive sulphide properties in the area.
