LIT’s Lithium Splurge

| February 18, 2016 | 4 Comments

Lithium_SplurgeAs the race intensifies for Lithium positioning in the first phases of what looks like a renaissance in interest in Lithium, we can dust off our old horse race analogy. As anyone in the racing business knows there are hundred-percent owners of thoroughbreds and other horses in which “investors” own shares. Lithium Australia NL (“LIT”, ASX:LIT) in its former guise as Cobre Montana got itself positioned during the down days when pretty much no-one gave a damn about Lithium. In the process it ended up with three “shared” ownerships:

  • Cinovec (with EMH)
  • Sonora (with Alix Resources)
  • Lepidolite Hills (with Focus Minerals Ltd on an 80/20 basis)

Beyond these three “runners” in the Lithium Stakes, LIT also has a 100% owned prospect in the form of what it calls the Ravensthorpe project, but which is also sometimes called Cocanarup. Frankly we prefer the latter name as Ravensthorpe is also synonymous with nickel mining.

In any case the general area has the Mt Cattlin mine, thus making the area more than just prospective for lithium, but an actual production zone. Indeed, the Ravensthorpe region is well-endowed with mineral deposits of many types and includes a broad range of mineral commodities. Indeed, like at Mt Cattlin, previous explorers mostly focussed upon the tantalum-potential of the pegmatites.

In this piece we shall review some recent results out of LIT’s Ravensthorpe territory.

In a Good Neighbourhood

It was only recently that we highlighted the reactivation of the Mt Cattlin lithium mine by General Mining (ASX:GMM) in a Joint Venture with Galaxy Resources (ASX:GXY). The Mt Cattlin is about 2km north of the Ravensthorpe townsite, as can be seen marked on the map below:.


Lithium Australia’s Ravensthorpe project, some 20 km southwest of the historic mining centre of Ravensthorpe, is comprised of granted Exploration Licence E74/543, is in close proximity to both services and infrastructure and contains a large number of pegmatites, broadly referred to as the Cocanarup pegmatites, some of which contain lithium minerals.

The Cocanarup pegmatites were reported in 1900, during the same phase of prospecting activity that led to the discovery of the Mt Cattlin pegmatites nearby.

The Cocanarup pegmatite field is comprised of three discrete pegmatite occurrences that intrude the greenstones of the Yilgarn Craton. These occurrences are the Quarry Pegmatite, Horseshoe Pegmatite and Eastern Pegmatite.

Quarry Pegmatite

The Quarry Pegmatite is the best known of the Cocanarup lithium pegmatites and a small pit (hence the “quarry” in its name) was excavated into its northern end, apparently to mine tantalite.

This deposit consists of two bodies that together outcrop for more than 1400 m along a north-south axis. Mapping by previous operators shows that the unit is between 15 and 40 m wide with a shallow, 20-degree dip to the west. Exposures in the quarry contain purplish lepidolite and coarse-grained rosettes of zinnwaldite (a type of Li mica, which ironically in named for LIT’s Cinovec deposit in the Czech Republic, which is known as Zinnwald in German), along with quartz and feldspar.

The tantalite has been proven to be columbite containing a high proportion of tantalum. The columbite occurs as discreet masses associated with zinnwaldite.

Horseshoe Pegmatite

With dimensions of 700 m by 500 m and a thickness of between 40 and 100 m, this is a U-shaped body in outcrop. Previous mapping observations reveal that the unit contains abundant masses of lepidolite, while recent field inspections have confirmed the presence of lepidolite masses at surface, where they weather to a pinkish colour.

Eastern Pegmatite

Exposed discontinuously for more than 2000 m along the eastern edge of the tenement, the Eastern Pegmatite has mapped thicknesses between 10 and 70 m. As with the Horseshoe Pegmatite, there are no fresh exposures; however, field observations indicate that the body contains rich segregations of zinnwaldite.

Samples of zinnwaldite and lepidolite, taken by LIT from historic excavations in the Quarry Pegmatite, as well as other areas in the region have been sent for leach testing and carbonate production.

Recent Exploration Results

It should be noted that the main work here thus far has been surface sampling. This naturally has a tendency towards cherry-picking the most propitious looking samples from outcrops or loose material. That said the outcropping is not just isolated but rather on a massive scale. This can be noted from the photo of part of the Horseshoe Pegmatite.


Initial results from across the property have confirmed the presence of at least seven lithium pegmatites. Assay results from 19 samples of lithium mineralisation from the lithium core-zones of all pegmatites range from 1.26% Li2O to 4.23% Li2O, with a mean of a very rich 2.96% Li2O.

These have lead the company to interpret these as early indications that the grade and scale of lithium mineralisation is of economic significance and warrants follow-up investigation. We would presume this means trenching and drilling.

When All Said and Done

In this business one sees a lot of news releases and they can become all somewhat of a blur of maps and tables. However, the latest release of LIT has a photograph that pokes you in the eye on mineralisation at the Quarry Pegmatite.


Combining this image with the grades that were yielded by the latest sampling makes the Cocanarup pegmatites start to look like a potentially very rich source of not only Lithium, but Tantalum as well.


To dust off one of our other analogies LIT is charging around the Monopoly board snapping up properties in all the best streets. Verily as we wrote this note it added another one in Western Australia cheek by jowl with Pilbara Resources Pilgangoora Lithium project, which has driven that stock to stratospheric heights. Not all these properties will move forward or not even move forward at the same speed but LIT is making sure it is positioned on prime real estate.

The latest exploration results show that LIT is a good “talent-spotter” and that the potential of Western Australia to become one of the two global hotspots for Lithium (the other being the Argentine salares) is far from exhausted. Now it’s time for LIT to repeat the trajectory of Galaxy and Neometals, drill Cocanarup into a resource status that will provide a fast path to production. The question then is what sort of economies of scale might be achieved by collaboration with its relative near-neighbour, Mt Cattlin.

We await more news on the work program on Cocanarup with high expectations.

    Great article, very informative and saved me a lot of leg work, thanks! Was playing around on their website yesterday to look up information and found this article captured it all. Keeping a close eye on this one Mr. Ecclestone. Look forward to an interview with Ms. Weslosky soon I hope!

    What kind of % Lithium are Li Australia hoping to see on these properties?

    Has the first photo been color-enhanced to emphasize purple and make the Li minerals stand out? Some of the vegetation is purple. Some of the shrubbery is a bizarre shade of green. There are purplish flowers. Do they really use pink stake flags? And the leather handle of my Estwing rock pick is a lot darker, as is the one in the second photograph.
    Take care,

    I was was just to put money in when they jumped.. That does not mean I have changed my long time idea of Lit and Tlg together.
