Deposit Type

  • Pegmatite


Summary:

Deposit Types
Frontier Lithium’s target or deposit model is the highly evolved, granitic, rare-element lithium-cesium-tantalum bearing (LCT) complex type, petalite subtype pegmatite. The Tanco pegmatite situated in the Bird River belt in southeastern Manitoba is the best known and a world-class example of this type of deposit model.

Of the five classes, the rare-element class is the group with the most attractive economic potential and can represent economic sources of tantalum, ceramic grade spodumene, rubidium, and the main cesium ore mineral, pollucite.The lithium rich, rare-element pegmatites are not common and comprise <0.1% of the total known pegmatites (Kesler, et al, 2012).

The rare-element class of granitic pegmatites is generated by the differentiation of fertile, S-type granitic plutons. This differentiation process of the parental granite is accompanied by the progressive accumulation of lithophile rare-elements as well as elements such as thallium, tantalum, hafnium, gallium, germanium, boron, fluorine, and phosphorus (Cerný and Ercit, 2005). The pegmatite field results when the lithophile rare-element enriched residual melt is expelled from the fertile granite and assuming suitable channels exist migrates outward and upward away from the granite.A field can be comprised of many pegmatites over a distance of a few kilometres from the source granite. The field itself shows an increasing fractionation moving away from the source granite.< ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Open Pit mining is the selected method of extraction for this PEA. The underground resource at PEA is not considered as part of this PEA.

The Open Pit mine plan was scheduled on an annual basis for the 25-year pit life of the Pak deposit and 25-year pit life for the Spark deposit.

The mining method selected for the project will be a conventional open pit, truck and shovel, drill and blast operation. Minimal vegetation, topsoil, and overburden will be stripped and stockpiled for future reclamation use. The mineralization and waste rock will be mined with 10 m high benches, drilled, blasted, and loaded into haul trucks with a hydraulic excavator and a loader for back-up.

The PAK Lithium Project is designed as a conventional truck-shovel operation assuming 36 nominal tonnes trucks and 5 m³ shovel. Mining at the PAK open pit is planned to produce a total of 5.5 Mt of material (2.9 Mt of chemical grade at average Li2O grade of 1.75 and 2.6 Mt of technical grade at average of Li2O of 1.90), 33.4 Mt of waste for a 1:6 overall strip ratio, for a period of 24 years (excluding 1 year of pre-production). Mining at the Spark open pit is planned to produce 17.2 Mt of mineralization and 48.6 Mt of waste for a 1:2.82 overall strip ratio, for a period of 23 years. The current life-of-mine (LOM) plan focuses on achieving consistent production rates in the production schedule, as well as balancing grade and strip ratios.
