Long Valley Exploration Project Drilling Project Approved
The Acting District Ranger of the Mammoth Ranger District has approved the categorical exclusion (CE) for
the Long Valley Exploration Drilling Project.
The project is approved based upon the proposed Plan of Operations submitted by the proponent, KORE
Mining, that is for mineral exploration only. An application has not been submitted or proposed for mineral
extraction (mining). If that were to occur, that application would be processed as a separate project and
have a separate National Environmental Policy Act analysis.
The initial Plan of Operations was revised based on analysis and comments received during project scoping,
and many requirements were added to minimize resource impacts.
This decision approves mineral exploration, including ground-disturbing reclamation activities, for up to one
The scope of this project will total approximately 0.82 acres; 0.43 acres would be from the drill pads and
0.39 acres from the use of the temporary access roads. Twelve drill pads, measuring 53 feet by 30 feet, will
be constructed and up to three core borings will be drilled on each pad. The proposed drilling equipment will
access the property across existing public roads and will utilize temporary access roads from the public
roads to the drilling pad locations to minimize disturbance from road grading. Best management practice will
be employed for drilling. The timeframe for these activities will be less than one year after drilling begins.
“This decision includes measures to minimize effects to natural and cultural resources by requiring postproject restoration for habitat improvement and monitors to protect cultural resources during drilling
activities,” Acting District Ranger Leeann Murphy said, “These restoration activities are important to provide
food and cover for native wildlife species, allow for native plant success, and ensure there is no net loss of
habitat and no effect to the capability of forest species of conversation of concern to persist over the long
term in the plan area.”
Activities such as monitoring, native seeding, and maintaining a sage grouse friendly fence to exclude
livestock from the restoration areas are in support of the post-project habitat restoration.
