Park, James 1906 The Cyanide Process of Gold Extraction, Fourth Edition, London: Charles Griffin & Co.
From 1979 through 1982, the Comstock Mill operated without a Plan of Operations or reclamation bond, receiving ore from area mines and extracting gold using the cyanide process and depositing mill tailings in an adjacent 40-acre, unlined, tailings impoundment.
The success of the efforts of Phillips with the mill encouraged others to employ the new cyanide process, which promised to renew productivity of mining on the Comstock and elsewhere: the innovative approach for extracting precious metal meant that lower grades of ore could become profitable, allowing for more productive excavations of ore within mining districts that had ceased operations.
