MORE INSIGHT INTO - RUBIDIUM Rubidium and caesium aluminyls: synthesis,
structures and reactivity in C–H bond
A recent review highlighted the growing recognition of alkali metal mediation, AMM, that underpins a diversity of applications in main group organometallic chemistry. AMM can be defined as chemical transformations that cannot occur at all or cannot take place efficiently, without intervention of an alkali metal. Expanding knowledge of low valent aluminium chemistry, rubidium and caesium aluminyls are reported to complete the group 1 (Li–Cs) set of metal aluminyls. Both compounds crystallize as a contacted dimeric pair supported by Mπ(arene) interactions with a pronounced twist between aluminyl units. Density functional theory calculations show symmetrical bonding between the M and Al atoms, with an Al centred lone-pair donating into vacant Rb and Cs orbitals. https://pubs.rsc.org/en/content/articlehtml/2022/cc/d1cc05379e RUBIDIUM COMES IN MANY COLORS Grey

MGX's press mentions the aluminum as causative to the
rosey coloration.... they also make mention of,
purple. I pointed out how rubidium is associated to, aluminum in
former post. ( rosey blushes )
Here is another
aluminum Rubidium called,
RUBICLINE. Rubicline, also referred to as Rb-microcline, is the rubidium analogue of microcline, an important tectosilicate mineral. Its chemical formula is (Rb, K)[AlSi3O8] with an ideal composition of RbAlSi3O8. Chemical analysis by electron microprobe indicated the average weight of the crystal is 56.66% SiO2, 16.95% Al2O3, and 23.77% Rb2O,[4] along with trace amounts of caesium oxide (Cs2O) and iron(III) oxide (Fe2O3).[5]

As one can see,
Aluminum plays a huge role with, rubidium + cesium.
With a variety of species and colors....
Rhodizite = green + rosey = rubidium.

INFINITY MINING DISCOVERS HIGH GRADE - RUBIDIUM
Where did they discover the rubidium ?
Iron and wearhered pegmatites ( lol )
High grade.
Does one chase white pegmatites on GC claims ?
Or, look to the grey + iron country rocks and, ask.....
Could all the rosey, limes, be.... Rubidium ?
Higher grade rubdiumm grey or iton source vs pegmatites ?
Where were the rock chip samples taken ?
Iron or grey rock, or from pegmatite dykes ?
Here's a photo of Infinity's Rb discovery...
Reminds me of GC's Iron with rosey quartz melt, atop.

------------------------------------------------------------------------------
So there you have it.
Run to the pegmatites....
Or, is the rubdium higher grade in the irons or, grey rock ?
-------------------------------------------------------------------------------
GC DRILL CORE - REPORT - HISTORICAL I've sifted through it....
Felspars, white carbonates, minor irons - stood out.
They were't looking for lithium or ree's.
So.... not much to go on.
Few clues, but sparce.
https://apps.nrs.gov.bc.ca/pub/aris/Report/13727a.pdf/ I myself have the impression, rubdium will be higher grade
and more abundant in the irons and grey - country rock.
Why ?
Rubidium does not compund or bond to lithium.
But rubidium does with iron, alumina silicates, felspars, potassium, etc....
Would love to see a ( few ) small holes. in greys and irons.
As seen in photo outcrops.
Wouldn't hurt to tap another 6 holes ( 30m ) each
eq to one drill hole
3 in grey
3 in irons
One could say, that highlighted list is a mix, iron + salts.
But, keep in mind.....without salts, rubidium cannot swap out.
Hence, if the pegmatites came forth ( into ) country rock,
the salts and alumina in pegmatites, would come in contact
with grey and iron country rock and perform the swap out.
Most Geo's will be attracted to the - white pegmatites,
thinking lithium and ree's....but as mentioned, rubidium
does not bond to lithium, which points to, greys + irons....
Other research papers do mention, ree's abundance in
sedimentey and irons host rocks....
Cheers....
