The Bureau of Land Management (BLM), Hassayampa Field Office has received a Draft Mining and Reclamation Plan of Operations (Plan) from Kirkland Mining Company (Kirkland) in order to develop a high quality pozzolan mine on approximately 76 acres of public lands and construct support facilities on four acres of private land owned by Kirkland within an approximately 160 acre project area. The project area is located north of Kirkland, in Yavapai County, Arizona (see Maps). The BLM has determined that the high quality pozzolan present at the site is an “uncommon variety” and as such is regulated under the General Mining Act of 1872.
Kirkland has described the proposed mine operation as the following:
Front end loaders would be used to load the high quality pozzolan onto trucks;
The high quality pozzolan would be crushed and screened on-site (primary processing);
In approximately five years, production is anticipated to be approximately 500,000 tons of high quality pozzolan per year;
Depending on market demands during the first five years, there could be between 30 to 85 truck trips per day; and
Overburden set aside during mining operations would be used for reclamation, which will include regrading and revegetation of disturbed areas.
Blasting is not included in the Plan. There would be no on-site secondary processing; all materials would be taken off-site by haul trucks to various locations north or south of the mine site on Iron Springs Road for further processing. The transportation network has not been identified. No use of chemicals in crushing and screening (primary processing) is being proposed.
On adjacent private land owned by Kirkland, there would be additional support facilities including:
A designated parking area to accommodate mine and support staff vehicles, idle mine equipment, and trucks awaiting loads;
Modular office and lunch buildings on either concrete foundations or blocks approximately, but not limited to, 25 feet by 60 feet;
Portable toilets (one during initial production phase and up to several at full production);
Storage buildings of variable sizes (approximately 24 feet by 24 feet and up to 40 feet by 80 feet), one of which would be used to service equipment as needed and would include a minimum 40-foot by 40-foot concrete pad;
A water storage tank (maximum 12,000 gallons);
A waste oil storage container (maximum 2,500 gallons); and
Miscellaneous equipment and materials including portable waste receptacles, and other facilities.
More detail on the proposed mine operations is included in the Plan, see Documents.
In order for the BLM to process the Mining and Reclamation Plan of Operations, the BLM will need to complete an environmental assessment (EA).
