XRD - XRF - ANALYZERSWhat is the difference between XRD and XRF?
XRD can determine the presence and amounts of minerals species in sample, as well as identify phases. XRF will give details as to the chemical composition of a sample but will not indicate what phases are present in the sample.
Perhaps both are rightful in their own respect.

Yeah, another post to answer , ( Tabulator on ceo.ca )
Almost certain,
i also suggested in post to employ a 3rd party independent to perform the XRF analysis - whereas Braveheart is separate from the independent results.
Secondly, where i feel the issue lies is at the point of,
2018 - Bravehearts discovery of -cobaltite.
2019 - Moose Mtn resource calculation.
1) Cobaltite was known of prior to the resouce calculation.
2) Moose Mtn did not include the cobaltite or other minerals with in the resource calculation.
3) Contract was signed for a 25% copper con
4) Cobaltite reports to the tailings.
5) Are tailings gerouped in the 25% comncentrate with a 75% ore with potential minerals ?
6) Further ttesting on cobaltite should have been performed.
7) As much as - completely different style of extraction to accommodate for all metal credits
Solution ?
- I wouldn't be much of a shareholder if i didn't offer a solution.
- Independent XRF analysis - 3rd party ( mine walls, all core from drills not just veining
sections, tailing from mine portals, tailings from pit waste, stockpiled ores.
- new extraction model that considers all - metal credits -
- if cobaltite was reporting to the tailings then, what other economical metals report to tailing ?
- Could the tailings see a secondary ( heavies ) concentrate that can be imparted inwhich
empties the waste ores of all minerals based on heavies - molecular weights ?
And as so, would Ocean then want the - 25% copper con with 75 % true waste ores ?
If not,,,, then , it would point to - the waste ores with original extractionaffords profiable
minerals with in.
Back tracking to the cobaltite and " other mineral credits " makes quick remedy.
As mentioned in numerous posts,
The best solution might be as simple as not erunning the high grade copper as other peers who have .25 - .30% copper.
A smaller junior who has upto 7x greater grades but less tonnage should consider not running the path of their peers with a concentrate.
Rather.., adopting a new format of,
electrolysis might command a far higher profit - margin.
Jump the gun and sign a contract with minerals that end up in - tailings ?
Wet tonnage soon changes to dry tonnage and just how many mineral credits are with in
the tailings - when... Braveheart + Moose Mtn perhaps should've performed a 30 point analysis on the ores inside and outside - veining material - to see what exactly they're dealing with before ( drawing + signing ) with Ocean.
I see it as an easy fix.
But... it's all how the junior precieves this...
Will they remedy or, continue course ?
Hard to say.
DOES - ALS - PROVIDE SERVICES FOR - XRF ?
You betchya they do.
One has must ask,
if a lab relies on XRF - then, it must cut the mustard.
Portable XRF on prepared pulps
ALS offers portable XRF analysis on pulps immediately after sample preparation at the prep lab closest to your project.

Now, what's not talked about in the industry is,
The results from - fire assaying + 4 part acid.
Many minerals are transitional minerals
Too much heat can perhaps - morph the targeted mineral in which may not be detected by certain methods -
Acids, dissolve,
and as so, i haven't come across any literature on the effects of - mineral loss or binding with other minerals upon acid dissolution. Once minerals are in solution - they can lattice bond with other minerals .
Now, where i have an issue with acid mineral testing is,
If labs are using a specific signature trait identifier and if the minerals were dissolved and happened to bond with another - compatable mineral - the signature identifier may no longer be identifiable. Thus, potentially a skewed end value - targeted mineral no longer able to detect.
raw analysis - own opinion.
using spectrometry or XRF XRD, could avert the side effects
of standard lab alaysis' that employ - screen fire assay or acid solvents.
