CGM (ASX) Amblygonite and it's economic uses

Originally posted by Elcorp ↑

The sample results in the 2nd Oct news release listed Pegmatite Rock and/or Amblygonite.
Pegmatites are extreme igneous rocks that form during the final stage of a magma's crystallization. They are extreme because they contain exceptionally large crystals and they sometimes contain minerals that are rarely found in other types of rocks.
To be called a pegmatite, a rock should be composed almost entirely of crystals that are at least one centimeter in diameter. The name pegmatite has nothing to do with the mineral composition of the rock.
Pegmatites are sometimes sources of valuable minerals such as spodumene (an ore of lithium)

So anything on that results chart (apart from those stated Amblygonite) could in fact be Spodumene.

Spodumene is a pyroxene mineral that is found, almost exclusively, in granite pegmatites. It has a chemical composition of LiAlSi₂O₆ but small amounts of sodium sometimes substitute for lithium. Spodumene is typically found in lithium-rich pegmatites in association with other lithium minerals such as lepidolite, eucryptite, and petalite.

While I'm on the topic. The DNPM 2012 survey identified 7 distinct areas as below.

Area 1: amblygonite and secondarily tantalite-columbite and beryl
Area 2: quartz k-feldspar, clevelandite, spodumene, lepidolite, amblygonite, cassiterite, muscovite, tantalite, beryl and tourmaline;
Area 3: amblygonite crystals up to 40 cm x 15 cm
Area 4: amblygonite, tantalite-columbite and beryl
Area 5: amblygonite, beryl and spodumene
Area 6: beryl main production, in association with microcline, afrisite, apatite and other phosphates;
Area 7: beryllium, mica and amblygonite

We haven't even scraped the surface yet. As further results are released and further testing is carried out I can see this developing into something quite exciting. Brazil was Randal's key project, prior to the Graphite deal popping up, and I'm sure he knew what he was doing then just as I'm sure he knows what he's doing now. He's not a 'city suit wearing MD', he's a seasoned expert. The LOI release below may be worth revisiting. Cheers, E
