Wildcat Silver, now known as AZ Mining Inc, recently announced plans to purchase the 300 acre historic Trench Camp Mine from Asarco Multi-State Environmental Custodial Trust. The custodial trust was formed as a result of a bankruptcy settlement with ASARCO and tasked with cleanup of the abandoned mine.
Mining stopped at the underground Trench mine over 50 years ago, which is located in the Patagonia Mountains adjacent to AZ Mining’s existing 154 acres of private land inholdings. The purchase “will greatly enhance AZ Mining’s surface lands for any future mining operations,” according to a press release.
The press release also stated that AZ Mining Inc “has submitted a remediation work plan that addresses the environmental liabilities with the Arizona Department of Environmental Quality [ADEQ] and will construct a passive water treatment system estimated to cost US$2.6 million, excluding contingency, of which the Company’s share will be US$1.6 million.”
This would be the third time in recent history that the Trench Mine has undergone remediation work. The mine was “largely remediated by ASARCO” in the 1980’s and 1990’s, according to an ADEQ report.
More recent work was necessary after the Trench tailings pile dam overflowed with acidic water loaded with toxic heavy metals when heavy rains hit the Patagonia Mountains in September 2014. ADEQ issued six violations of state water-quality rules as a result of that spill.
AZ Mining Inc takes on these environmental issues with the purchase of the Trench mine. Wendy Russell, PARA Coordinator, told the Weekly Bulletin that she is doubtful the situation will be improved. “I’m really concerned about the environmental issues that we have with the Trench Mine, and if they’ll actually clean it up,” she said.
