Key Points

  • Commencement of Phase 1 Drilling: MAX Power Mining Corp. has initiated Phase 1 drilling at its Willcox Playa Lithium Project in Arizona. The drilling follows a comprehensive analysis of historical data and results from the 2023 geophysics program. Geologists now have a model for potential significant discoveries, and this marks the first systematic diamond drilling at the Playa.
  • Geological Highlights and Targets: MAX Power is strategically positioned with a first-mover advantage in the approximately 50 sq. miles (129 sq.km) Willcox Playa, surrounded by essential infrastructure. The company is targeting a claystone sequence below the Playa, with a thickness of up to 1,600 meters, and exploring trapped non-potable fluids with potential lithium brines. Pervasive resistivity anomalies detected through recent surveys suggest the presence of lithium targets, and a review of historical data indicates the prevalence of clay minerals conducive to lithium concentration.
  • Lithium Concentration Model and Exploration Focus: The deposition and concentration model for lithium at Willcox Playa involve erosion of source rocks, transportation to a brackish lake, hydrological closure, and concentration over time. The Playa basin’s unique geological features, including apparent structural controls and the nearby Turkey Creek Caldera, contribute to the potential for lithium accumulation. The company has identified large anomalies through geophysical surveys and established drill targets across its property, emphasizing the prospect of lithium accumulation and concentration.

MAX Power Mining Corp. (CSE: MAXX; OTC: MAXXF; FRANKFURT: 89N) (“MAX Power” or the “Company”) is pleased to announce that Phase 1 drilling has commenced at the Company’s Willcox Playa Lithium Project in Arizona. Compilation of historical data combined with results from MAX Power’s 2023 geophysics program has given geologists a model for a potential significant discovery at the Playa where first-ever systematic diamond drilling is now in progress.

MAX Power has first-mover advantage at Willcox where the Playa comprises approximately 50 sq. miles (129 sq.km) in an area with nearby infrastructure, surrounded by roads, rail, power and services provided by a nearby community.

Discovery Model Highlights:

  • MAX Power is targeting both a property-wide claystone sequence below the Willcox Playa, which has a thickness of up to 1,600 metres, and trapped non potable fluids with the potential to host lithium brines;
  • MAX Power has defined pervasive and significant resistivity low anomalies across most of its 3,754-acre property. Extreme resistivity lows, detected through a recent HSAMT Survey, most probably represent clay-rich sediments, which could comprise lithium targets extending from near-surface to depth;
  • The HSAMT Survey suggests these anomalies are persistent to depths of at least 600 metres below the surface with the thickness of the clay sequence estimated to be 1,200 to 1,600 metres;
  • In addition to the anomalies, the geophysical cross section highlights what appears to be a series of sub-vertical parallel structural controls, possibly faults, that are known in similar settings to concentrate lithium in desert playa environments;
  • A comprehensive review of historical data suggests that illite and montmorillonite, associated with the weathering of silicic volcanic ash tuffs, are the most common clay minerals under the Willcox Playa. Illite at Willcox is described as the “dominant” clay mineral in a PhD thesis. Its formation in a geothermally active, alkaline environment is often significant and can aid in the concentration of lithium. This clay mineral is known to contribute to high-grade lithium values in other claystone lithium deposits.

Lithium Concentration Model at the Willcox Playa

The current model for the deposition and concentration of lithium on and under the Playa involves four key steps:

1) The erosion of the Apache Leap Tuffs (~18.5 Ma), the proposed source rocks which surround much of the playa (Chiricahua Mountains to the south, the Dos Cabezas mountains to the east and the Dragoon and Little Dragoon Mountains to the west, and the Galiuro-Winchester mountains to the north);

2) The material eroded from the source rocks was then transported to the centre of the valley into a very large brackish lake named Lake Cochise. The Playa is a mere remnant of Pleistocene aged Lake Cochise;

3) The basin is hydrologically closed, and the fluids for the most part do not exit, other than by evaporation. This created a concentration and compaction of the deposited materials over time. The result was a dry lake with a clay package up to one mile (1,600 metres) thick beneath the current land surface. Refer to Figure 1, a general outline of the source rocks, deposition and concentration;

4) The nearbyTurkey Creek Caldera is proposed as an important heat source to drive geothermal springs in the area and add to the concentration of lithium within the Playa basin.

Geophysical Anomalies

When looking at Figure 2, large anomalies are noted as seen by the colours blue and yellow. Values for the anomalies can be less than 1.0 Ω m (Ohm metre). Figure 2 is a plan view slice of the anomalies 100 metres below the surface. The Company has drill targets ranging over 10 km from the far north to the far south of the property to target these anomalies. The gravity low identified by the survey near the centre of the Playa often overlays the anomalies. The HSAMT and gravity surveys strengthen the possibility of lithium accumulation and concentration under the property.

Interpreted Structures (Resistivity)

Figure 3 is a cross section looking to the northwest. The section shows the resistivity values along the entire length of the Willcox Property. The cross section shows four sub-vertical interpreted structures spaced approximately 3,000 metres apart along the cross section. The geophysical interpretation suggests these apparent structures have some degree of influence on the distribution of anomalously low resistivity anomalies. At Clayton Valley, Nevada, structures are important in concentrating lithium in brines. There, according to Davis et al. (1986), the brines most enriched in lithium are in the down-faulted portion of the Playa. They also stated the highest lithium concentrations are found in brines produced from the tuff where it contacts faults, producing local structural traps for brines.

Historical Context

The Willcox Playa, situated approximately 200 miles southeast of Phoenix in Cochise County, was historically referenced by the U.S. Geological Survey (USGS), following limited drilling in the 1970’s, as one of the most prospective locations for lithium in the western United States, similar in its potential to Clayton Valley, Nevada, and the lithium brine and claystone deposits that have been identified there. Decades of U.S. Air Force activity in the Willcox Playa has ended, with MAX Power benefiting from first-mover advantage in the area.
