Mine Life30 years (as of Jan 1, 2019)
Lithium South expects to expand the known resource with its current drill program. Preliminary results support this expectation. Additional project work including permitting, environmental studies and process test work is ongoing.

Deposit Type

  • Brine


Summary:

The deposit type is a brine aquifer within a salar basin. The conceptual model for the Hombre Muerto basin, and for its brine aquifer, is based on exploration of similar salar basins in Chile, Argentina, and Bolivia. Salar basins are characterized by closed topography and interior drainage. The lowest exposed portions of these basins may contain salt encrusted playas, or “salars”. Typically, no significant groundwater discharges from these basins as underflow. All groundwater discharge that occurs within the basin is evaporated. All surface water that flows into the basin is either evaporated directly or enters the groundwater circulation system and is evaporated at a later time.

Salar basin locations and basin depths are typically structurally controlled but may be influenced by volcanism that may alter drainage patterns. Basin-fill deposits within salar basins typically contain thin to thickly bedded evaporite deposits in the deeper, low-energy portion of the basin, together with thin to thickly bedded low-permeability lacustrine clays. Coarser-grained, higher permeability deposits associated with active alluvial fans can typically be observed along the edges of the salar. Similar alluvial fan deposits, associated with ancient drainages, may occur buried within the basin-fill deposits. Other permeable basin-fill deposits which may occur within salar basins include pyroclastic deposits, ignimbrite flows, lava-flow rocks, and spring deposits.

Mining Methods

  • Brine mining


Summary:

Well holes with internal pumps will be used to transfer brine to one of three pre-concentration ponds located near the processing plant. At present there are two holes on the property that are drilled to 400 m depth and are suitable for production brine pumping. An estimated 100 L/s of brine will be required to feed the ponds and processing plant sufficiently to achieve the targeted production rate of 5,000 t/a of Li2CO3. Three well holes will be required to achieve this rate. An additional four holes will be drilled during the pre-production period, bringing the total to six and providing double the well requirement as a contingency.

A production rate of 5,000 t/a of Li2CO3 has been targeted for the project. This rate was selected as a reasonable starting level of production, with the potential for expansion once commercial production and/or payback has been achieved.

A 30-year production forecast was assumed for the Project. A production rate of 3,750 t/a was assumed for the first operating year (75% of full production) and a rate of 4,500 t/a was assumed for the second year of operations (90% of full production). All remaining years were scheduled at the full production rate.

The production forecast therefore contemplates a total extraction of 148 kt of Li2CO3 equivalent, approximately 56% of the resource.
