BAY MAG Was researching Baymag -
Can't find any current mg reserve data - all data thus far that i've come across is old intel.
The only current date i could find is their - 5 drill holes - Aris Report.
BAYMAG The 5 holes drilled have high calcium content - making it less desirable Mgo.
Pages - 40-ish onward.
https://aris.empr.gov.bc.ca/ArisReports/37842.PDF What piques my interest is...
BayMag's deposit is in same vicinity as, Driftwood.
One would think the deposits would have similar grades.
Could it be... different testing methods ?
Onwe method includes the LOI while another lab separates the LOI from the MgO ?
BayMag reports - Mgo in the 97% range - no LOI mentioned.
When analyzing their drill data - all other minerals along with the Mg add up to the 100% content of
ore characterisits...
While MGX's shows a 43% Mgo with a few tag alongs of, Alum, Cal, Iron, Silica.
Low in each seondary mineral making it idea for a minable deposit.
So... how does MGX's report differ from BayMag ?
MGX shows the - LOI.
LOI = life of ignition - of the MgO.

I've yet to see this - LOI - value in any of the BayMag's reports.
I may have missed it.. but, it is odd.
What did i just come across today ? Study on regulators of purifying magnesite ore by cationic reverse flotation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8379186/ More importantly.... This study has a special table ( chart ) that breaks down the ore contents = arriving at grade.
If one compares the first two columbs ...It has similar grades to that of Driftwood.
Refer to chart at end of this post - Magnesite Ore
Magnesite So.. how does a 47% grade increase to 92% + 98% ?
LOI - is added in.
Like the chart suggests... ( L+I ) = O
Life + Ignition = Oxygen.
So.,. could it be....
Adding in the LOI - arrives at a total - MgO ?
If one 9 again ) refers to MGX's report above - many of the ( MgO + LOI )
values if combined would flirt with the 90-ish % MgO
Is BayMag including their - LOI - in their overall Magnesium deposit percentage values ?
Should MGX
combine their - LOI - with thier Mgo deposit percentages ?
I'm no magnesium pro...
But... maybe another could chime in.
Chemical composition of magnesite ore, and single mineral magnesite, dolomite, and quartz (wt%).
Sample | MgO | CaO | SiO2 | Al2O3 | Fe2O3 | LOI | MgO (IL = 0) |
Magnesite ore | 46.01 | 0.75 | 2.38 | 0.13 | 0.23 | 50.5 | 92.95 |
Magnesite | 47.35 | 0.25 | 0.19 | 0.34 | 0.17 | 51.70 | 98.03 |
Dolomite | 22.24 | 29.99 | 0.64 | 0.34 | 0.15 | 46.5 | |
Quartz | 0.08 | 0.01 | 99.4 | 0.22 | 0.01 | – |
Cheers...
