Alpha Lithium Announces Positive Preliminary Economic Assessment Results for Tolillar Project in Argentina






  • US$1.5 billion (CDN$2.0 billion) after tax NPV8 with an IRR of 25.1%
  • US$5.3 billion (CDN$7.1 billion) of cumulative free cash flow over a 25-year mine life
  • 3.8-year after-tax payback period from start of production
  • Significant upside potential remains from recently drilled wells not yet included in this PEA


Alpha Lithium Corporation (NEO: ALLI) (OTC: APHLF) (German WKN: A3CUW1) a company developing a portfolio of highly prospective lithium assets in Argentina, today announced the results of a Preliminary Economic Assessment for its wholly owned Tolillar lithium brine project in the Salta Province of Argentina. The PEA provides an independent economic assessment of the potential value of Tolillar, based on the lithium resources outlined in the September 2022 Resource Estimate (see news release August 23, 2022).


The PEA evaluated a 25,000 tonnes per annum commercial-scale operation to produce battery-grade lithium carbonate chemicals. Importantly, the study does not include contribution from wells drilled since mid-2022, which management believes represent meaningful, unquantified, upside potential. Alpha intends to soon incorporate drilling completed since mid-2022, and anticipates an expanded resource could potentially support a longer mine life and a second 25,000 tpa phase, for an aggregate 50,000 tpa operation.


Brad Nichol, President & CEO of Alpha commented, “The results of the PEA demonstrate that Alpha’s Tolillar project is an exceptionally robust lithium carbonate project, even with conservative assumptions. Tolillar represents one of the last, large, independent, wholly-owned lithium brine salars globally, and once the latest technical work is incorporated, Tolillar should become an even larger and longer-lived operation. Additionally, with its substantial fresh-water source on site, it is not difficult to understand why Tolillar is such a sought-after target.” Nichol added, “I am very pleased with the speed at which Alpha’s team has advanced the Tolillar project from a greenfield site to PEA. To demonstrate the viability and significant economic potential of such a project speaks to the abilities of our unique team of experienced lithium specialists.”


PEA Highlights:


  • US$1.5 billion (C$2.0 billion) after tax NPV with an 8% discount rate and IRR of 25.1%
  • Average Li2CO3 price of $22,990 per tonne, over 25 years of production
  • After tax payback period of 3.8 years from start of production
  • After tax, cumulative free cash flow of US$5.3 billion ($C7.1 billion) over a 25-year production life
  • Initial capital cost of $777 million (includes contingency of $179 million)
  • Brine mining and processing cost, excluding Li2CO3 transport of $5,150 per tonne
  • Cash cost of $6,301 per tonne (includes mining, processing, transportation, and royalties)


The PEA was prepared by Ausenco Chile Limitada, a global engineering firm, experienced in the lithium industry. Ausenco has prepared multiple economic assessments and feasibility studies, specifically for, but not limited to, South American lithium brine extraction companies over the past several years. In addition to being DLE and production process experts, Ausenco’s knowledge was invaluable for assessing current and conservative operating and capital costs, which incorporated the latest global cost estimates. All values are reported in US dollars, unless otherwise noted. References to CDN$ have been converted at 1.35 x US$.


Economic Analysis and Summary:


Lithium chemicals produced from brines are almost universally less expensive than those produced from hard rock, giving brine operations a significant competitive advantage. Specifically, the Tolillar project benefits meaningfully from the following:

  1. Immediate proximity to (10-15 km from) Livent’s Fenix Project, which has produced approximately 20,000 tpa of lithium carbonate chemicals for over two decades. Tolillar will dramatically benefit from the existence of a national high-grade highway (6 km away) connecting the project to supplies and services, a nearby (6 km) high-pressure natural gas pipeline with existing capacity, nearby (90 km) 3-phase power, and nearby (90 km) international rail lines.
  2. A significant freshwater discovery on the north, south and west sides of the Tolillar salar, with the western discovery being capable of supporting a major lithium chemicals plant, on its own.
  3. A proven DLE-based production process, built upon a process that has been tested and utilized for over two decades in Argentina. Alpha’s production technology has been developed by an expert team with unmatched, hands-on, DLE and production experience.
  4. Being the sole owner of the Tolillar salar eliminates potential conflicts or competition for production, fresh water, equipment, and personnel.


The Discounted Cash Flow Model, generated independently by Ausenco, with an outside consultant providing tax estimate advice, demonstrates an attractive economic result from the potential production of lithium carbonate chemicals from the Tolillar project. As a result, the Company expects to continue construction of its 120 tpa pilot plant, which will provide the necessary data to support the design and feasibility study for the 50,000 tpa lithium carbonate chemicals plant envisioned by Alpha.

The PEA NPV results take into account royalties that are specifically applicable to the Tolillar project.


With over $30 million of cash on hand, Alpha is well financed to complete this work and has a strong technical team with extensive lithium experience leading its efforts in Argentina.


Initial Capital Costs:


Description US$ millions
Direct Costs:  
Brine Extraction Wells $35.7
DLE Plant $107.5
Reverse Osmosis $67.8
Chemical Plant $27.7
Purification $22.5
Dry Product Handling $27.5
General Utilities $68.1
Infrastructure $43.1
Direct Costs Subtotal $399.8
Indirect Costs $197.6
Contingency $179.2
Total Initial Capital Costs $776.6


Total estimated initial capital costs are $776.6 million for the first phase (25,000 tpa) of lithium carbonate chemicals. Contingency costs are estimated at 30% of total direct and indirect costs. Capital costs for the second phase (a second 25,000 tpa) are not included in this PEA analysis; however, management expects those to be approximately 35% lower than the capital costs for the first phase by utilizing economies of scale.


Operating Costs:


Description US$/year US$/tonne Li2CO3
DIRECT Operating Costs:    
Chemical Reactives and Reagents $73,397,431 $2,936.20
Energy $23,408,421 $936.30
Manpower $6,169,100 $246.76
Catering and Camp Services $4,556,000 $182.24
Maintenance $5,148,319 $205.90
Site Vehicle Costs $286,800 $11.47
Bus-in/Bus-out Transportation $548,000 $21.92
Consumables $625,000 $25.00
Li2CO3Transportation $2,875,000 $115.00
Resin and Membrane Replacement $11,728,817 $469.15
Sub Total DIRECT Costs* $128,742,823 $5,149.94
Sub Total INDIRECT Costs $2,915,500 $116.62
TOTAL Processing Cost (excluding Transportation)* $128,783,323 $5,151.56
TOTAL Production Cost (including Transportation)* $131,658,323 $5,266.56

*Numbers may not add up due to rounding.


The estimated operating costs are current as of Q1 2023 and reflect 100% year-on-year cost increases in some cases, such as for chemical reagents, which dramatically increased due to ongoing COVID-19 related global supply chain constraints. Management supports the use of potentially temporarily inflated costs and believes the cost estimates are appropriately conservative in light of many reported cost overruns in the industry. Finally, the second largest cost center is “Energy,” accounting for 18% of the total operating cost. Alpha management has previously investigated and utilized solar power to provide energy to similar and larger projects in the past; however, solar power was not incorporated into the PEA at this time. Utilization of solar power should dramatically decrease the estimated operating cost.


Lithium Markets and Price:


Alpha consulted industry experts at Global Lithium LLC for estimates of long-term market and pricing dynamics. Recently, the price of lithium carbonate has been volatile, ranging from $5,000/tonne in 2018 to over $80,000/tonne in China’s spot market in 2022, before moderating in 2023. Even during the most recent period of spot market volatility, long-term contract prices outside of China remained relatively constant in the $60,000/tonne range, on average, through April 2023.


For estimating future cash flows from new projects, Global Lithium LLC and Alpha recommended a conservative approach, using a price significantly below (approximately 50% of) the upper end of the expected long-term marginal cost curve, yielding conservative project economics that leave room for significant upside. While most forecasters do not forecast prices beyond 2030, Global Lithium LLC recommended using a price of $22,500/tonne from 2031 to 2035 and a price of $23,500/tonne from 2036 and beyond.


Year Li2CO3Price (US$/tonne)
2025 $22,500
2026 $21,000
2027 $21,000
2028 $21,000
2029 $21,750
2030 – 2035 $22,500
2036 – beyond $23,500
Average price for 25-year production life of Tolillar project $22,990


The PEA is based upon brine grades across the company’s Measured, Indicated and Inferred Mineral Resources only. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no certainty that the Tolillar project envisioned by the PEA will be realized. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.
