Lithium Brine Program

LITHIUM BRINE PROGRAM

American Potash lithium exploration/development rights in UT are held in 11 State of UT mineral leases (Lithium, K, Bromine, etc.) totaling 7,040 acres, and 308 Federal placer mining claims covering 6,160 acres, which provide exploration and development rights for Lithium and Bromine. Lithium exploration and development rights in Colorado are controlled via 608 lithium placer mining claims totaling 12,160 acres.

Subsurface brines are commonly encountered during oil and gas drilling at widespread locations in the Paradox Basin. In 2012 AMP became aware of significantly enriched lithium concentrations within subsurface brines (brine aquifers) in the Paradox Basin, hosted primarily by the clastic stratigraphic layers separating the Paradox Formation evaporite sequences. In 2016 AMP began acquisition of 308 Federal lithium claims (6160 acres) within the bounds of their Potash exploration permit application area of interest (AOI) and, in conjunction with the approximately 7,040 acres of Utah State lithium leases, now possess approximately 13,200 acres of lithium claims and leases in Utah. In late 2016 and into 2017 AMP began acquiring lithium mining claims in the Colorado portion of the Paradox Basin, focused on two areas with historic and current oil and gas exploration and production. American Potash’s Colorado lithium claim position now totals approximately 12,160 acres.

Unlike our competitors in the Paradox Basin and elsewhere, AMP control rights to potassium as well as lithium and bromine within the area of the Utah lithium mining claims and State leases due to the juxtaposition of the lithium mining claims and their potash prospection permit application AOI. This unique situation will allow AMP to take advantage of all potentially economic elements contained within the rich multi-commodity Paradox Formation brines, specifically lithium, potassium, and bromine, which are all known to occur in high concentrations in Paradox Basin brines. The multi-commodity nature of the Paradox Formation brines is unique to large marine sedimentary basins due to the original sea water source of the present day dissolved solutes/metals, unlike the South American and Nevada dry lake bed (“salar”) brines which comprise most of current world-wide lithium production.

Utah Lithium Brine Project

In 2016 AMP began acquisition of Federal placer lithium claims and Utah State lithium leases in the Utah portion of the Paradox Basin and within the confines of AMP’s existing Potash Prospecting Permit application AOI. American Potash currently control 308 Lithium mining claims (6,160 acres) and 7040 acres of Utah State mineral leases allowing exploration and development of lithium, potash, bromine and other elements within an area totaling 13,200 acres.

American Potash’s lithium mining claims and Utah state lithium leases cover known brine-hosting clastic stratigraphy in the Paradox Formation. Over-pressured brine production was recorded in the well log of historic oil and gas well Federal 1-26 located within the boundaries of AMP’s lithium claim block, and historic well Shell Quintana located approximately 3 miles north of the Lithium claim block at the northern boundary of the AMP potash permit application area. Further, significant lithium concentrations ranging from 87 ppm to 500 ppm have been measured in brines produced from the same brine-hosting stratigraphy as Federal 1-26 in several wells in the Long Canyon and Big Flat areas of the Paradox Basin, located approximately 10 miles south of the AMP claim block. The documented occurrences of Li-enriched subsurface brines from several wells in the Paradox Basin, and the occurrence of highly saline brines beneath the AMP claim area, are considered very encouraging relative to the potential success of AMP’s Lithium exploration program.

According to terms defined by the JV agreement with PWM, AMP plan to drill one test well targeting known brine aquifers beneath their Utah State leases within 6-months of the JV signature date and a second well targeting the same brine aquifers beneath their Federal lithium mining claims within 6-months of completion of the first.

Colorado Lithium Brine Project

American Potash, recently (Q1, 2017) acquired 608 US Federal placer mining claims, totaling approximately 12,160 acres, in the southeast extension of the Paradox Basin in San Miguel County, southwest Colorado. Approximately 1/3 of the Paradox Basin extends southeast from Utah into the State of Colorado, including thick sections of Paradox Formation evaporate (salt bed) stratigraphy. The new mining claims occur as two blocks located over part of the southeast extension of the Paradox Basin’s Paradox Formation and locally underlying Leadville Limestone stratigraphy from which lithium-bearing brines have been documented in five historic oil and gas wells (ranging from 87 ppm to 500 ppm lithium) and one historic potash exploration well (730 ppm lithium). The new Colorado claim blocks also encompass parts of the southeast extension of the Lisbon Valley Anticline, Gypsum Valley Anticline and associated fold and fault belt structures that create traps for hydrocarbons and, potentially, aqueous brines as well. Well logs from an historic potash exploration well (Standard Oil 88-21P) located in the Lisbon Valley area near the Utah-Colorado border document incidental brine production from a Paradox Formation clastic unit containing 730 ppm lithium-oxide (339 ppm elemental lithium). This well is located approximately 5 miles northwest of AMP’s new Southeast Lisbon Valley claim block in Colorado.

The two new Colorado claim blocks encompass existing operating and shut-in oil and gas wells, many with reported co-produced brines. American Potash are currently in negotiations with the well-field lease owner and operator regarding procurement of an agreement allowing AMP to access and sample co-produced brines from their oil and gas production wells. Occurrence of lithium in potentially diluted co-produced oil-field brines proves existence of lithium in brines in this part of the basin, but does not necessarily represent potential levels of lithium concentrations in individual Paradox Formation hosted brine aquifers. Collection and analyses of samples from specific, discrete brine aquifers will be required to determine their actual lithium concentrations, which can potentially be accomplished via re-entry of shut-in wells and/or completion of new wells.
