Lithium One Delineates Resource of 5.4 Million Tonnes Lithium Carbonate Equivalent and 21.3 Million Tonnes Potash Equivalent at Sal de Vida Brine Project, Argentina


- Among the largest and highest grade lithium-potassium brine resources in the world(1)

- Fully independent inferred resource estimate includes:

-- 5,440,000 tonnes lithium carbonate equivalent

-- 21,300,000 tonnes potash equivalent

-- Average Li grade 695 mg/L

-- Average K grade 7,590 mg/L

- Near-surface deposit has significant potential for expansion:

-- Resource covers only 65% of the project area containing known high-grade lithium and potassium brine

-- Resource to only 140 metres depth and deposit is open below

- Since June of 2010, the Korean Consortium has funded US $6.3 million of an estimated US $15.0 million budget through feasibility.

VANCOUVER, CANADA--(Marketwire - March 7, 2011) - Lithium One Inc. (the "Company") (TSX VENTURE:LI), is pleased to report its first independent lithium ("Li") and potassium ("K") resource statement for its Sal de Vida brine project at Salar del Hombre Muerto, in Salta and Catamarca provinces of Argentina. The inferred resource estimate, prepared by E.L. Montgomery and Associates, is summarized in Table 1 below and includes 5,440,000 tonnes of lithium carbonate ("Li2CO3") equivalent and 21,300,000 tonnes of potash ("KCl") equivalent. These values represent contained lithium expressed as lithium carbonate and contained potassium expressed as potash. The Sal de Vida deposit has emerged in this initial resource estimate as one of the largest and highest grade undeveloped lithium brine deposits in the world1 with significant expansion potential. 

Patrick Highsmith, the President & CEO of Lithium One, commented on the maiden resource for the Sal de Vida Project, "We are very pleased that after just 18 months we have established a large and extremely high quality lithium and potash brine resource that ranks amongst the largest in the world. This work clearly confirms the significance and quality of the Sal de Vida deposit, while the on-going production of lithium carbonate and potash from our pilot recovery plant demonstrates the robustness of our simple and low cost processing system. These excellent developments are major steps towards bringing Sal de Vida into commercial production."

The resource estimate was prepared in accordance with the guidelines of National Instrument 43-101 and uses best practice methods specific to brine resources, including a reliance on core drilling and sampling methods that yield depth-specific chemistry and effective (drainable) porosity measurements. The resource calculations were also confirmed using three different resource models. The work was completed by independent qualified person Mr. Michael Rosko of the international specialist hydrogeology firm E.L. Montgomery & Associates (M&A).

All resources are reported at a 500 mg/L lithium cut-off, meaning any blocks of brine in the model containing less than 500 mg/L lithium were excluded from the inferred resource estimation. In addition, the resource was calculated only to the depth of each exploration well, even though almost every well bottomed in an aquifer containing lithium and potassium rich brine.

The resource is defined entirely with core drilling and it lies within 140 metres of the surface. It is open at depth, as well as laterally to the south and northwest. The core drilling program continues with both infill drilling and step-out holes into areas known to contain near surface brine rich in lithium and potassium. The footprint of the initial resource is approximately 16,900 hectares, whereas sampling of surface brines has identified high lithium and potassium values over more than 26,000 hectares.

The consistently favorable low magnesium and sulfate content of the resource confirm that the chemistry of the Sal de Vida brine is very similar to that produced by FMC Corporation at its adjacent Fénix Project. Some important parameters of the brine composition are:

  • Average density of the brine: 1.19 g/cm3
  • Average Magnesium/Lithium ratio: 2.19
  • Average Sulphate/Lithium ratio: 10.76

Based on current stratigraphic information, approximately 65% of the brine volume in this resource is hosted by predominantly sandy aquifers and 13% by at least one large halite (common salt) body. The balance is hosted in silt, travertine, gravel, or clay dominated units.

The total contained lithium and potassium values are based on measurements of effective (drainable) porosity distributed throughout the aquifer volume that defines this resource. This method of porosity determination is designed to estimate the portion of the total porosity that can reasonably be expected to be drained by pumping; however, these in situ estimates may differ from total extractable quantities. The porosity of the resource volume varies with geology but to date effective porosity has been predictable by hydrostratigraphic units; and the average for the entire database is approximately 7.9%. These porosity values compare favourably to other commercial lithium brine operations, such as FMC's Fénix Project that adjoins Sal de Vida on the west. The average effective porosity in the Fénix reserve is approximately 7%(2).

Maps, sections, and additional information about this resource will be available on the Sal de Vida Project page of the Company's website

Resource Estimation Methodology

A total of 1232 metres of drilling from 10 holes was evaluated for this resource calculation. The total number of drainable porosity results used in the computations was 122, and the total number of brine samples used in this resource calculation was 119 (not including QA/QC samples). The average spacing of vertical samples for both drainable porosity and chemistry is approximately 10 metres. Of the 10 holes used for the resource analysis, only one reached the base of the basinal sediments; all others were terminated after reaching target depth or due to drill limitations. The total thickness of the basin, and the total thickness of saturated sediments, is unknown for most of the basin.

In order to confirm the results, the consultants chose to estimate the resource using three different methodologies: two variations of a modified polygonal technique ("Methods 1 and 2") and Kriging using a linear variogram ("Method 3"). The inferred resource reported here was calculated from the standard polygonal method, Method 1. Hydrostratigraphic units have variable thickness and were determined by the consultants based on anticipated similar hydraulic properties. The values for drainable porosity and grade (lithium and potassium values) for each hydrostratigraphic unit were derived from direct measured values from the well. The unit thicknesses combined with the areas yield a volume. The volumes combined with the drainable porosity values, representing the amount of fluid available from the formation, yield the tonnage of brine. Applying the grade, represented as lithium carbonate and potassium chloride equivalents then provides the estimated resource for each block, which are then summed.

The resource tonnages from Methods 2 and 3 confirm and validate the reported results as a rigorous and conservative estimate of the contained lithium and potassium resources. The results from all three models will be described in the NI 43-101 Technical Report to be filed on SEDAR and posted on the Company's website (

The primary analytical laboratory for the data used in this resource is Alex Stewart Assayers of Mendoza, Argentina. Alex Stewart's Mendoza lab is accredited to ISO 9001:2008 and ISO14001:2004 for its geochemical and environmental labs for the preparation and analysis of numerous sample types, including waters. The details of analytical methodologies and quality assurance protocols were reported in the Company's first NI 43-101 Technical Report, which was filed on SEDAR in 2010.

The porosity determinations were made by Core Laboratories of Houston, Texas. Core Laboratories is a leading provider of proprietary and patented reservoir description, production enhancement and reservoir management services. Core Laboratories has demonstrated that its Quality Management System is in compliance with certification to ISO 9000:2008. The scope of this registration is: providing state of the art petrophysical and geological analysis and interpretation of core samples from rock
