Highest Uranium Extraction Combined with Lowest Acid Consumption Achieved In Leach Testing at Macusani

Share it

VANCOUVER, British Columbia, Feb. 16, 2022 (GLOBE NEWSWIRE) — American Lithium Corp. (“American Lithium” or the “Company”) (TSX-V:LI | OTCQB:LIACF | Frankfurt:5LA1) is pleased to announce excellent uranium leach test results from recent work completed at Australian Nuclear Science and Technology Organization (“ANSTO Minerals”) and TECMMINE Mineral Processing Consultants, based in Lima, Peru. These results are from work carried out on uranium mineralization from five of the Company’s uranium deposits on the Macusani Uranium Project (“Macusani”) in southeastern Peru and confirm excellent extraction, low acid consumption and short leach cycle times.

ANSTO Minerals is a globally respected consultancy with world leading experience in uranium and lithium processing and played a key role in proving the ability to produce battery grade lithium carbonate from Falchani. While COVID 19 caused significant disruption in Australia with delays and closures impacting most businesses including ANSTO, with the situation now improving, the Company anticipates that ANSTO will be a key contributor as the Company looks to update PEAs on Macusani and Falchani and release its maiden PEA on TLC.

Highlights

  • 91.0 to 98.0% Uranium extraction using weak sulfuric acid at ambient temperatures;
  • 97.0 to 99.7% Uranium extraction using sulfuric acid at elevated temperatures (60-95°C) and a variety of acid concentrations;
  • Weaker acid concentrations obtained similar uranium extractions (pH 1.8-1.5 versus pH 1.2); and
  • Results demonstrate the ability to extract even higher levels of uranium than previously demonstrated, with lower acid consumption.

Simon Clarke, CEO of American Lithium states, “We continue to refine our processing options at the Macusani as we await the grant of final permits to commence the resource expansion and in-fill drill program which will also support an updated Macusani PEA. These recent results confirm the outstanding leach characteristics of Macusani mineralization. The high recoveries, low acid consumption and short leach cycles combined with previously announced positive gravity pre-concentration results should result in additional improvements to the already robust economics for this globally significant uranium project.”

ANSTO Minerals Diagnostic Leach Test Work Report – Detailed Results:

  • Uranium mineralization from the Colibri and Kihitian deposits was leached at ambient and elevated temperatures using dilute sulfuric acid, varying initial acid concentration, temperature and leach time in a series of initial diagnostic leach tests;
  • Leaching of high-grade Kihitian mineralization (2,345 parts per million [“ppm”] Uranium [“U”]):
    • Ambient temperature leaching (20°C) achieved 97.9 – 98.0% U extraction at pH 1.2, 1.5 and 1.8 using a 12-hour leach time for each test;
    • Elevated temperature leaching (60, 75 and 90°C) achieved 99.5 – 99.7% U extraction in a 24-hour leach cycle;
  • Leaching of lower grade Colibri mineralization (211 ppm U)
    • Ambient temperature leaching (20°C) achieved 91.0 – 93.4% U extraction at pH 1.2, 1.5 and 1.8 using a 12-hour leach time for each test.
  • Conclusions/Observations:
    • Mineralization is hexavalent uranium mineral autunite, which does not require oxidant addition;
    • Solution data indicates that extraction was complete in 6 hours for ambient temperature leaching;
    • Leaching with lower acid concentrations than previous test work (pH 1.8 versus pH 1.2) obtained similar excellent uranium extractions, with resulting lower acid consumption; and
    • Final leach solution compositions are clean with no issues expected in Ion Exchange (IX) uranium recovery; indicates low gangue mineral dissolution and low acid consumption at low temperature.

TECMMINE Leach Test Work – Detailed Results:

  • Mineralization from Corachapi, Chacacconiza, Chilcuno was leached at ambient and elevated temperatures using dilute sulphuric acid, varying acid concentration, temperature and leach time in a series of tank leach tests;
  • Leaching of Chilcuno mineralization (606 ppm U) at 95°C for 3 hours achieved 97.0% U extraction with 28 kilograms per tonne (“kg/t”) acid consumption;
  • Leaching of Chacacconiza mineralization (243 ppm U) at ambient temperature (20°C) for 6 hours achieved 95.2% U extraction with 20.1 kg/t acid consumption; solution data indicates that U extraction was essentially complete in 3 hours;
  • Leaching of Corachapi mineralization (217 ppm U) at ambient temperature (20°C) achieved 92.0% U extraction after 2 hours with 8.7 kg/t acid consumption; and
  • Leaching of upgraded Corachapi mineralization (468 ppm U) at ambient temperature (20°C) achieved 93.8% U extraction after 4 hours leaching with 11.1 kg/t acid consumption.

Macusani Project Plans

  • Extension and exploration drilling at Macusani utilizing two Company diamond drills will commence upon receipt of final permits;
  • A planned 12,000 metres (70 holes) of diamond drilling targeting expansion of current uranium deposits/resources, test new radiometric anomalies, and follow-up high grade, near surface exploration targets identified in 2021 field work where 90 grab samples1 averaged 18,270 ppm (2.15% U3O8); and
  • Update historic PEA (2016) by Q4, 2022:
    • Focus on economic benefits of gravity pre-concentration which has successfully doubled the feed grade and has potential to significantly increase throughput / life of mine using additional resources not previously included;
    • Include any additional resource defined during drill program into future PEA mine plan;
    • Include results of on-going metallurgical leach and precipitation test work; and
    • Produce sufficient quantity of yellowcake product for chemical and commercial assessment.

Notes
1 Grab samples are selective, and the selected nature of such sampling does not necessarily reflect potential uranium contents expected from future drill testing, however, they do indicate the presence of uranium mineralization and mineralizing systems in the surface rocks collected.

Investors should not place undue reliance on forward-looking statements. Cautionary Note Regarding Macusani Concessions Thirty-two of the 151 concessions held by American Lithium’s subsidiary Macusani, are currently subject to Administrative and Judicial processes (together, the “Processes”) in Peru to overturn resolutions issued by INGEMMET and the Mining Council of MINEM in February 2019 and July 2019, respectively, which declared Macusani’s title to 32 of the concessions invalid due to late receipt of the annual validity payments. In November 2019, Macusani applied for injunctive relief on 32 concessions in a Court in Lima, Peru and was successful in obtaining such an injunction on 17 of the concessions including three of the four concessions included in the Macusani Uranium Project PEA. The grant of the Precautionary Measure (Medida Cautelar) has restored the title, rights and validity of those 17 concessions to Macusani until a final decision is obtained at the last stage of the judicial process. A Precautionary Measure application was made at the same time for the remaining 15 concessions and was ultimately granted by a Court in Lima, Peru on March 2, 2021 which has also restored the title, rights and validity of those 15 remaining concessions to Macusani, with the result being that all 32 concessions are now protected by Precautionary Measure (Medida Cautelar) until a final decision on this matter is obtained at the last stage of the judicial process. The favourable judge’s ruling confirming title to all 32 concessions from November 3, 2021 represents the final stage of the current judicial process. However, this ruling has recently been appealed by MINEM and INGEMMET. American Lithium has no assurance that the outcome of these appeals will be in the Company’s favour.
