<br /> <br />• EXHIBIT T -ENVIRONMENTAL PROTECTION PLAN <br />1.0 INTRODUCTION <br />Battle Mountain Resources Inc. (BMRI) extracted and beneficiated precious metal at the San <br />Luis Mine Project from January 1941 to November 1996 under permit M-88-112 from the <br />Colorado Division of Minerals and Geology (CDMG). Mining and beneficiation activities took <br />place approximately four miles northeast of the town of San Luis in Costilla County, Colorado. <br />Since the temtination of mining and beneficiation activities at the San Luis site, BMRI has been <br />conducting surface land reclamation and closure-related surface and groundwater monitoring. <br />All lands utilized by the project are privately owned. <br />Ore extracted from the surface mine facilities were beneficiated through a cazbon-in-]each (CIL) <br />circuit to recover the precious metal concentrations. The tailings material generated from the <br />miIUCIL circuit were deposited in acomposite-lined, tailings disposal facility (TDF). The <br />milllCIL circuit was designed and operated to provide containment and collection of any spills <br />within the facility operations. The TDF was designed and is managed as a zero-dischazge facility <br />containing water from the CIL circuit and stormwater flows from the Probable Maximum <br />Precipitation (PMP) storm event. <br />Since the termination of operations at these facilities in 1997, all chemical reagents and <br />beneficiation solutions associated with these facilities have been either removed ftlom the site or <br />chemically neutralized and placed in the TDF for final disposal in accordance with <br />reclamation closure plans authorized and approved in the CDMG permit. <br />[n July 1998, closure-related groundwater monitoring identified an exceedance of permit <br />condition values at a West Pit monitoring well (M-11R) which resulted in the development of <br />Technical Revision (TR) 26, "Water Management in the West Pit Area, San Luis Project, <br />Costilla County, Colorado," in accordance and compliance with the CDMG permit• Subsequent <br />to the development of TR-026 and further investigation and remediation actions associated with <br />the groundwater exceedance, BMRI has implemented measures for the construction and <br />operation of an active water treatment facility to treat groundwater in the vicinity of the West Pit <br />at the San Luis Project.
