Exploration Strategy for Lithium:

The exploration strategy will target the discovery of pegmatitie-hosted lithium deposits. The program of work will evaluate the whole of the land subject to the application for lithium mineralisation by compilation and consideration of results from historical exploration over and near the tenements, and interpretation of airborne geophysical data and detailed systematic filed exploration program, including regional soli and stream sampling program.

This currently intended to be followed by infill sampling of anomalous areas possibly other geophysical surveys to define drill targets, followed by drill testing if justified.

Lithium (from Greek: λίθος lithos, "stone") is a chemical element with the symbol Li and atomic number 3. It is a soft, silver-white metal belonging to the alkali metal group of chemical element
Lithium is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable.

Because of its high reactivity, lithium never occurs freely in nature, and instead, appears only in compounds, which are usually ionic. Lithium occurs in a number of pegmatitic minerals, but due to its solubility as an ion, is present in ocean water and is commonly obtained from clays.

On a commercial scale, lithium is isolated electrolytically from a mixture of lithium chloride and potassium chloride.

Maximum concentrations of lithium found in samples of flint clay (white clay) and associated rocks of North & South America and Western Australia. The formation of lithium-bearing kaolin deposits are positive induction of high grade of Lithium.

The maximum concentration found in the bauxite region such as Guyana is 460 ppm and that in flint clay in North America is 370 ppm. Previous samples from areas are relatively representing mostly commercially valuable clays alumina silicate with Lithium compound and represent only a part of the refractory clay deposits in the North America.

In samples containing more than 2000 ppm lithium, the lithium occurs in a dioctahedral chlorite mineral very similar to cookeite, which previously has not been recognized in sedimentary clays. The associated clays consist chiefly of well-crystallized kaolinite. Lithium-rich clays could serve as a significant lithium resource in the very distant future.

Alumina Silicate – Lithium rich white clays in Guyana potentially may supplier of high grade lithium, same as Greenbushes near future.

Spodumene is a mineral with a hardness of 7 out of 10 on the Mohs scale of mineral hardness. These Monoclinicly structured gems are made of lithium aluminum silicate, their full chemical compound being LiAl (SiO3)2.

Spodumene is a lithium aluminum silicate that crystallizes in the monoclinic system. It is one of several rock-forming minerals in the Pyroxene group, which are physically-related as their chemical content is quite similar and forms a chain. Fellow pyroxenes are jadeite, enstatite, diopside, hypersthene, augite, acmite, hedenbergite, pigeonite, and aegirineaugite.

It appears as prismatic crystals, sometimes gigantic. One sample was 16m long and weighing several tons, with vertical striations. It also forms rodlike aggregates of cryptocrystalline masses, like gelatinous masses that slowly solidified.

Crystals can be whitish, yellow, gray, pink (kunzite), or emerald-green (hiddenite). It is a trichroic mineral, changing color depending on the angle at which it is viewed. It is hard, heavy, has perfect cleavage parallel to the vertical prism. It is transparent to translucent, with vitreous luster.

It is insoluble, fuses easily, coloring the flame crimson (lithium). Spodumene occurs in lithium-bearing pegmatites associated with quartz, feldspars, lepidolite, beryl and tourmaline. It is often subject to layer alteration, turning mixtures of various minerals, including clays, albite, muscovite, eucryptite, etc.

Morabisi and Greenbushes:

Guyana Morabisi Tenements has got geological and geophysical similarity same as Greenbushes and Mt Marion (WA) mines.

The Greenbushes pegmatites belong to the Lithium-Caesium-Tantalum family. The Greenbushes pegmatite deposit intrudes along a major northwest regional fault zone. It is approximately 2,525 million years old. The pegmatite consists of a large main zone over 3 kms long and up to 300 m wide with numerous smaller pegmatite dykes and pods flanking the main body.

The Greenbushes pegmatites are mineralogically zoned in a lenticular interfingering style along strike and down dip. The lithium zone is over 2 kms long and enriched in the lithium-bearing mineral spodumene which often makes up 50% of the rock.
