Ann: Addendum to ASX Announcement dated 5 June 2023, page-13

I have also been very interested in caesium - which showed up in rock chips from memory.

I am guessing caesium would only be detected via chemical assay

Cesium Wars: Why Are China and North America Fighting Over This Rare Metal? | OilPrice.com

Some highlights:

Critical minerals represent one of the most pressing present and future national security issues for the Western world. The Canadian government should be cautious in accepting Chinese investment in its crucial mining sector while creating new opportunities and reducing future risk for investors.The rarer the mineral is, the more critical to national security. Access to rare metals is essential to gaining technological superiority, which in turn dictates superpower status. It’s the East-West battle of the century, and the critical mineral Cesium (Cs) is a key element at the heart of it all.

Cesium is so critical that its value is in the realm of the priceless.

Cesium bromide is also used in infrared detectors, optics, photoelectrical cells, scintillation counters, and spectrometers. Critical use goes beyond this, as well, with cesium isotopes necessary for maintaining atomic resonance frequency standards in atomic clocks (think: aircraft guidance systems, global positioning satellites, and internet and cellular telephone transmissions).

5G technology is expected to rule the world because it can create a continuous, real-time connection for every single device that exists and every single device that will be made because of it. The new 5G cellular wireless tech will transfer data and the correct time faster than ever before--fast enough and accurately enough to transform industries. None of it can happen without cesium.Meanwhile, China is forging ahead with its Huawei-led plans for 5G (and global) domination.

With three critical commodities on offer—lithium, cesium and tantalum—in our opinion, Case Lake is shaping up to be one of the most important mining venues to watch on the planet.

Note the company mentioned - Power Metals - has sold its offtake to Winsome Resources.

The MD of Winsome Resources, Chris Evans, just so happens to be a Non-Executive Director of Askari.
