MT BRUSSLOF - NIOBIUM Here's another PDF research paper discussing the Mt Brussloff - Niobium.
The Niobium is from the species of, Fersmite.
What's interesting about this study is....
They found that the niobium runs with the - calcium .
Most other carbonate deposits the niobium runs with - tantalum.
At the Mount Brussilof magnesite deposit,
fersmite is an erratically distributed trace mineral. The fersmite-bearing zone, now mined out, was approximately 10 m long, irregular, and porous. It consisted of sugary dolomite and sparry dolomite that cuts sparry magnesite.
The zone was exposed a few metres from a pyrite stockwork in the sparry magnesite. The Mount Brussilof fersmite forms brittle, black, acicular to platy crystals up to 2 cm long with a submetallic to vitreous lustre that line cavities in sparry dolomite. In some cavities, fersmite occurs with euhedral quartz (Fig. 3). Fersmite also occurs as smaller crystals enclosed in dolomite
Fersmite ([Ca,Ce,Na][Nb,Ta,Ti]2 [O,OH,F]6 ) is hosted by the sparry dolomite or by sugary dolomite enclosed in the sparry dolomite.

reveals the calcium to Niobium ratio in sample ore.
Good Read - short and sweet - ( 2019 ) 11 pages.

Yes... i have to say it....
Our most recent bulk samples were only from, magnesite ores.
And even then - calcium and other impurities were taken out of the bulk samples.
This is where the Fersmite hosts. ( calcium )
I wouldn't fully rely on the - pdf study - above.
I would still do a thorough check on all dolo ores, specifically colored ores.
As one can read in the pdf - lots of other ree's are found in the dolomites.
Look at the uranium - values.
Appears, BayMay missed this mineral credit - mined out their fersmite long ago.
But then again...
this research ( paper ) suddenly shows itself on line.
I did several searches on Baymag, and nothing showed.
Wait a few days... research again -
another paper comes forth - proving - BayMag has the ree's.
Now today - this one shows up.
Almost like someone's releasing - pdf's - as i research.
I won't complain - lol
In the paper it does mention fersmite is black....
But... it also mentions these colors -
Primary fersmite is less common. It occurs mainly as prismatic crystals that are predominantly tabular, bladeshaped, or acicular. Crystals are black, dark brown, or lemonyellow to yellow-brown, and their luster varies from resinous to subvitreous or submetallic. Many dark-colored crystals are nearly opaque, fl uoresce yellow-green to bluish-green under shortwave and longwave ultraviolet light, and have a pale blue cathodoluminescence (Anthony et al., 2017).
There's a photo - on page - 3 -
Rock sample looks.... blusih - purple ( fermite )
Driftwood has pret near al lthe colors - mentioned above.
.
We don't even know if our Geo is doing a second take -
more samples taken from the colored dolos -
would be nice to know.
Cheers....
