The Top Ten


  1. One of the larger salars in the world to be drill tested with a 4,250 meters (14,000 feet) in 12 drill holes starting in late April, 2019. The lithium industry and global investment community are watching.
  2. A large property covering 75,400 hectares or 290 square miles.
  3. All 83 geochemical samples over 80 kilometers assayed for lithium with an average grade of 78 parts per million(ppm) lithium. 59 of these geochemical samples have an average grade of 86 ppm lithium that defines a geochemical anomaly covering 150 square kilometers. As surface samples, these results are anomalous and are a higher grade than some lithium-brine producers.
  4. The geological conditions that are necessary to develop lithium brine are present at the Property, which include the presence of hot springs, a volcanic source rock containing lithium, fault structures, a closed basin (meaning that water does not escape the basin), and a regional volcanic heat source.
  5. Initial geological analysis indicates an extensive and active structural environment including both north-south and lateral faults that are present throughout the survey area.
  6. Geophysical survey results identified 3 large highly conductive zones that cover more than 54 square kilometers and likely indicates the presence of brines.
  7. Zone One may be more than 100 meters (300 feet) thick and zone three may be more than 200 meters (600 feet) thick.
  8. The salar is estimated (based on prior gravity surveys) to be 8,000 feet deep at the western margin and could contain lithium-bearing aquifers that may be stacked to depth.
  9. The Salar del Diablo is located 35 km from San Felipe, which is a regional service center that will likely reduce exploration and development costs. It also has a seaport that may be used to ship product worldwide, including Asia.
  10. The Salar del Diablo is about the same size and has similar geologic attributes as the Salar de Atacama, which produces 27% of the world ‘s supply and is the world’s largest lithium /brine producer.

Salar del Diablo Lithium Property


The Salar del Diablo is a 75,400 hectare (290 square miles) property that covers a large salar. The Property is located in the State of Baja California Norte, Mexico.

Approximately 20% of the property has been explored by geochemical sampling, a geophysical survey, some geological mapping, and satellite imagery structural analysis. A time domain electromagnetic survey consisted of 80 line kilometers composed of 7 lines spaced two kilometers apart that covers 150 square kilometers.

Geophysical Program
Results to Date


  • The geophysical survey results defined three major conductive zones that could be indicative of brine, which cover more than 54 square kilometers. Two of the three zones extend beyond the limits of the geophysical survey and are open ended.
  • Syd Visser, President of SJ Geophysics Ltd. noted “The survey’s objective was to delineate changes in conductivity that could represent conductive layers. The Salar del Diablo was considerably more conductive than expected. As in other salars in North and South America that are in production or advanced exploration, the conductive layers could represent saline brines, which may contain elevated concentrations of lithium.”

The conductive zones identified by SJ Geophysics are:

Zone Two: Light Blue


  • Surrounds Zone One;
  • Is less than 100 meters (300 feet) thick;
  • Is also very conductive with reading of 2.0 ohm.m which is the average value of readings that range from 1.5 ohm.m to of 5.0 ohm.m;
  • Covers 24 square kilometers, which includes Zone One in the center; and
  • Is open ended to both the north and south beyond the survey grid.

Zone Three: Light Pink


  • Is a continuously conductive zone located beneath a resistive layer;
  • Is both east and west of Zone Two. Interpretation suggests the west side has likely been down faulted and may be originally related to Zones One and Two;
  • Is located at 300 meters deep at the south end and shallows to 200 meters as the overlying sediments decrease in thickness;
  • Is estimated to be 200 meters (600 feet) thick;
  • Is continuously conductive with ohm.m varying between 5 and 10 ohm.m; and
  • Is open ended to both the north and south off the grid.
  • Zone three covers more than 30 square kilometers

Geochemical Program
Results to Date


  • Over a distance of 80 kilometers, all 24 initial geochemical surface samples contained lithium with an average grade of 74 parts per million (ppm) lithium. Within the area of the geophysical survey, 59 additional samples have an average grade of 86 ppm lithium, which defines a 150 square kilometer lithium anomaly. For surface samples, these lithium grades are higher than other producing lithium brine properties. The samples also assayed as high as 1.9% potassium, an average grade of 400 ppm boron, as high as 10,000 ppm cesium, and a low average grade of 1.3% magnesium.
Samples 320 to 379 are the 59 samples referred to above

Geological Results to Date


A geological map has not been completed. However, evaluation of satellite data, known tufa mounds (relic hot springs) and outcrops indicate intra basin structures exist including faults in bedrock outcrop found outside the basin that trend into the Salar.

There are north-south active faults and cross cutting linears that could be cross faulting throughout the basin and adjacent bedrock outcrops.

There are two evident features:

1.) the geophysical Zone One appears to be constrained at the north and south ends of the survey area by a significant increase in cross faulting; and

2.) the cross faulting appears to dominate the east side of the basin and bedrock complex. These features suggest that conditions may exist to concentrate brines.


USGS-defined geologic attributes necessary to concentrate lithium in a brine are present at Salar del Diablo are:

  • 1. a closed basin
  • 2. presence of hot springs
  • 3. volcanic rocks enriched with lithium
  • 4. active faults that may allow for transport of lithium into the salar basin
  • 5. within a region of high heat flow.

Drilling Program


Twelve drill hole locations have been selected to test all three geophysical highly conductive zones an anomalous geochemical target and geological structures. The drilling program will be approximately 4,250 meters (14,000 ft). Some of the holes are placed near to interpreted structures to test both the structural setting of the basin as well as the potential existence of aquifers that may contain lithium. The Company plans to drill in late April, 2019.

Drill holes 1 and 2 will test geophysical Zone One which is 6 km square and likely more than 100 meters thick;

Drill holes 3,4, and 8 will test geophysical Zone Two that is more than 24 kilometers square and less than 100 meters thick:

Drill holes 5 and 6 will test Zone Two’s southerly extensions;

Drill holes 7, 7A and 10 will test both geophysical Zones Two and Three. Zone Three may be more than 200 meters thick and is greater than 30 square kilometers, being open ended to both the north and south; and

Drill holes 9 and 11 are sited to test the 150 square kilometer geochemical anomaly that is external to the geophysical survey footprint.

The Phase Three drilling program includes permitting, site preparation, and drilling to determine the existence of aquifers. If found, the aquifers will be tested for thickness, permeability, porosity, initial flow rates, sustainable flow rates, sampling, and analysis for lithium and other minerals.


Future Programs


Additional programs may include a gravity survey to establish basin configuration and to confirm the basin's interpreted 8,000 foot depth. Time domain electromagnetic (TEM) surveys may be conducted to close the open ended conductive zones 2 and 3 delineated in the first TEM program. After suitable surface exploration work is completed, a second pre drilling program may evaluate the remaining 80% of the property that is south of the initial drilling area.


Salar del Diablo Property Interests


One World Lithium Inc. has funded phase one and phase two pre drilling programs and now owns an undivided 60% working interest in the Property.

On completing the phase three drilling program and paying the Energy Metal discovery Group $150,000 and 400,000 shares, One World will have then earned an additional 20% working interest for a total of an 80% working interest.

On receipt of a bankable Feasibility Report, the Company has a one-time election to purchase an additional 10% working interest based on a Bankable Feasibility Report’s present value using a 10% discount rate for a total of an undivided 90% working interest.
