TORONTO (miningweekly.com) – Potash project developer Prospect Global Resources on Wednesday announced that it had received its air quality control permit for the construction and operation of an underground potash mine and surface processing facilities from the Arizona Department of Environmental Quality.
The company said the air permit was for the emissions from a 2.2-million-ton-a-year, two-train processing plant and related mine production, as planned in the company’s December 2011 preliminary economic assessment.
Prospect Global said that despite the permit allowing for a two-train operation, it was evaluating building only one of the two processing trains and related mine output with correspondingly reduced emissions.
The current infill-drilling programme was also expected to be complete in the next two weeks, and Prospect Global expected to publish an updated National Instrument 43-101-compliant resource report by the end of the year.
The mine and facilities would be located about 50 km south-east of the city of Holbrook, in Apache county.
