Falchani is an exploration property located on the Macusani Plateau and falls within licenses held by Macusani Yellowcake S.A.C (Macusani Yellowcake), formerly Global Gold S.A.C, which is 100% controlled and 99.5% owned by Plateau Energy Metals.

On May 11, 2021, American Lithium Corp. acquired all of the issued and outstanding common shares of Plateau Energy Metals Inc., resulting in Plateau becoming a wholly-owned subsidiary of American Lithium.

Deposit Type

  • Breccia pipe / Stockwork
  • Sedimentary - Volcanogenic


Summary:

Limited mineralogical work has been undertaken by SGS Canada on samples from the Falchani Project, and the understanding of the stratigraphy has evolved through exploration mapping and drilling programmes. In the immediate vicinity of the boreholes drilled at Falchani, the youngest rocks would appear to be these described in the field by Plateau Energy Metals as the Upper Rhyolite. The Upper Rhyolite forms prominent outcrops, and demonstrates a crude bedding, and appears to have a shallow dip to the north-northeast. Outcrops of the Upper Rhyolite have a similar appearance to the acidic tuffs of the Yapamayo and Sapanuta Members of the Quenamari Formation, which host the uranium mineralization.

This together with the fact that the Falchani Project is mapped as being underlain by the Sapanuta Member of the Quenamari Formation, support the interpretation. Below the Upper Rhyolite is the Upper Breccia, which separates the Upper Rhyolite from the Lithium-rich Tuff. The Upper Breccia is not well defined in outcrop but is very distinctive in core. The Upper Breccia contains angular clasts of volcanic material, in a very fine groundmas. The Lithium-rich Tuff is a light grey to white, very fine grained rock, with prominent layering.

Although the Lithium-rich Tuff has been further sub-divided, on the basis of its chemistry, these subdivisions are not immediately recognizable in outcrop or in core, and the term Lithium-rich Tuff is used to describe the whole unit, ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Open pit mining is planned to use conventional truck and shovel mining methods with drill and blasting to break the rock mass into manageable particle sizes. Mining operations are planned to be undertaken by a contractor operated fleet, which is the cost basis for this preliminary economic assessment.

The following design parameters where used for the PEA study revision:
• Fully mobile production equipment, consisting of medium sized hydraulic shovels and 90 tonne rigid dump trucks has been planned;
• Total mining costs of $2.40/t of material moved at altitude is the basis for the Project economics;
• Support equipment will be Front End Loaders, tracked dozers, graders, and water trucks;
• The run-of-mine (RoM) pad at near the Process Plants primary crusher will be the mining and process battery limit;
• Benchmarked operation elevation of 4,700masl was used;
• Optimisation of mining sequencing to minimise the waste stripping costs in phase I of the production ramp up;
• 10m waste benches, with stacking of 2 benches was basis of the design used to access mineralized material to a maximum depth of 200m;
• Geotechnically designed slope are applied to relevant pit areas.

Waste dump will be planned in accordance with environmental constraints and located around the pit edges once it has been confirmed that there are no additional mineral resources in these areas.
