@The_Jow And I'm wondering whether what's called "spodumene" is actually a mix of spodumene with many of the other Li-bearing silicates, like petalite, eucryptite,.... Which probably will influence the quality of the ore.

@Aryal_RajaRam @EarthObsAu Thanks so much for sharing @Aryal_RajaRam. And thanks #AEO22 for giving me the opportunity to present. Great conference!

@GenevievMarquis @GSC_CGC @cjmlawley @AASappin @LarmagnatS @Roger_Paulen @JesseyRice @dpettsy @vshear @nikole_bingham @RockMunki @nat7shea There are hyperspectral drill core data plus high res RGB imagery available from across the Mount Isa Inlier made accessible by the #AuScopeNVCL. These can be fed into ML algorithms for various purposes.

@stargonewrong @StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy Hyperspecteal IR remote sensing can be done at distance. See #Crism for example

@StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy I'm also wondering about the atmospheric windows on Mars: I assume these are at different wvl ranges, compared to Earth!? If so, wvl ranges could be used for SWIR imaging, that we can't use on Earth. Thinking of the 2700 to 3500 nm range, which is swamped by atm water on Earth.

@StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy A shortwave infrared imaging system would be useful for identifying the rock type base on the SWIR-active mineral assemblage

@StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy 3/3 providers/manufacturers are for example plotlogic, specim, itres, hyspex,....

@StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy 2/3 a good SNR in the 2000 to 2500 nm wvl range is crucial for discrimination of hydroxylated silicates and sulphates.

[Carsten Laukamp @CarstenLaukamp]

@StevenDJBaumann @BluRayHush @unsc1325 @ThePlanetaryGuy 1/3 One could use a hyperspectral SWIR camera, such as the ones used for mine face imaging and remote sensing.

@nalinarileo @murpharoo It is explained in the same article in the Guardian, accessible via the quick guide after the 2nd paragraph

@PwC_AU "The next generation of critical minerals miners will focus on extraction, processing, refining and, potentially, manufacturing to deliver a more secure and higher-value supply chain" It all relies on advanced resource characterisation and exploring for the right mineral deposit

[Carsten Laukamp @CarstenLaukamp]

@Strandjunker Maybe its time for introducing a maximum wage. Of course, in conjunction with minimum wage.

[Carsten Laukamp @CarstenLaukamp]

@JannisNoltsch @mxkell @rbb24 Ja. In Australien. Nach vier Jahren - realistisch.

[Carsten Laukamp @CarstenLaukamp]

@ixfoduap @EmmaRAndersson Of course, you'll have the same issue when the reviewers don't understand the papers they review

[Carsten Laukamp @CarstenLaukamp]

@ixfoduap @EmmaRAndersson I think that would lead to publication of even more low-quality papers. Problem is that most readers don't have sufficient knowledge about the published topics and, therefore, can be mislead by low quality papers.

[Carsten Laukamp @CarstenLaukamp]

@INN_Lithium Like Jilmenez hinted at, just because there's Li in lepidolite doesn't mean it can be extracted efficiently.
We need to move on from element-based resource estimations to mineral-based resources estimations.

[Carsten Laukamp @CarstenLaukamp]

@AuScopeNVCL @DrJessStromberg Very interestingly, we also discovered during the workshop together a potential relationship between Mn geochem alteration and the λ of SWIR vibrational modes of chlorite!

@RangaYogeshwar Danke @RangaYogeshwar! Ich stimme voll und ganz mit Ihnen ueberein!
