BACKGROUND – LITHIUM BRINE DEPOSITS

General Characteristics and Geology Salars can be classified according to “mature” and “immature” end members. “Immature clastic” salars are characterised by significant thicknesses of clastic sediments with gypsum dominated evaporite interbeds, with porosity and permeability characterised by primary depositional features, which can be highly variable given the nature of the sediments.

The clastic controlled characteristics can extend to several hundred metres depth – the recent drilling by Galan at Salar de Hombre Muerto has demonstrated this with the maiden hole (C-01-19) intersecting porous, lithium brine rich sediments down to at least 365m depth.
“Mature halite” salars are characterised by high permeability at shallow levels, however this decreases rapidly with increase in depth due to salt recrystallising and sealing fractures – in these salars exploitable resources are limited to shallow depths, generally down to around 50m.

The immature salars are commonly found at higher and wetter elevations, with the mature type at lower and more arid elevations; however some salars exhibit both styles, with Salar de Hombre Muerto being a prime example - the western basin is a mature system, with the eastern (including Candelas) being an immature system.

A number of factors are essential in the formation of lithium rich, potentially exploitable saline brines:
– Arid climate
– low rainfall,
– High evaporation rates,
– Closed basin, with ongoing tectonic SUBSIDENCE
– Suitable lithium source rocks: and,
– Thick aquifers with permissive porosity and permeability to allow efficient extraction of the brines.

Ongoing hydrothermal activity is also considered important for a number of reasons, including enhancing leaching of lithium from source rocks amongst others.

Tried to copy this diagram from several sources but it won’t play the game.

Unfortunate really as it answers many questions as to why GLN has chased this paleochannel.

It’s interesting how keen they were to get down to hope 2
after hole 1 and if they believe that what’s going on at Candelas is essentially the same as in this diagram then it’s highly likely they think some of the main hydrothermal source is down around this part of Candelas.

Again for those interested here’s the full Munk item.Probably posted before but what the hell.

Ps Weatherman there’s stuff in The Assay item that might help but as SMR and a few other have found it’s all in the drilling now imo.
