punch in 100 ppm - look at the percent value
= .01%
https://www.rapidtables.com/math/number/PPM.html
scale it up using - 100 ppm
100 ppm of 1,000 ppm = 10% ( 1,000 ~ 100 )
100 ppm of 10,000 ppm = 1% ( 10,000 ~ 100 )
100 ppm of 100,000 ppm = .001 % ( 100,000 ~ 100 )
100 ppm of 1,000,000 = .0001 % ( 1,000,000 ~ 100 )
now let's crunch the numbers
1,000,000 ppm = 1 kg or 1 liter
1,000 liters or kg's = 1 tonne
if we multiply - 01 % ( of every kg ) x 1,000 kg's in a ( tonne )
= 1,000 x .01 = 10 kg
now if we multiply 100 ppm ( per each kg ) x 1,000 kg's in a ( tonne )
= 100,000 ppm
ppm - is always tied to - per kg or liter
ppm - is not per tonne
CONCLUSION
using the the percentage ( .01 % ) of each kg multiplied by 1,000 units = 10 kg
remeber - 100 ppm represents = .01 % - there are 1,000 units of these in - 1,000 kg
using the ppm ( `100 ppm ) x 1,000 units = 100,000 ppm per - 1,000 kg
this metric math is not absolute.
why ?
becasue 100 ppm and .01 % should both arrive at the same value.
therefore - 100 ppm is not .01% and .01 % is not 100 ppm
online ppm calculators are skewed.
my own opinion.
inorder for it to work correctly...
100 ppm per 1,000,000 ppm per kg - online calculator must equate to - .0001 %
Im not a fan of using ppm - when, particles are in suspension in fluid.
Or... ppm in mass - especially - copper - becasue copper can take on many forms.
even lithium ,or other salts...al lbecause another mineral can bond to the salt mineral.
if only lithium is being tested - a lithium molecule can bond to borite, or other, and
the result will be a missed - lithium value - in a bond.
Therefore - lab must look for multiple bonds - in which the targeted mineral is hitrching a ride.
if, sulphuric acid is used - and copper is malachite or azurite - transitioned.
what if the ( sulphuric - acid ) doesn't solubilize the copper int osolution - can't detect it ?
transitional minerals - salts - copper - other metals...
makes one wonder how many lab reports - may have missed the target mineral ?
when you tihnk about it... copper when introduced to a rhyolite/feldspar or iron - ore,
and the copper oxidizes and morphs... i'd bet there's been many a juniors with dud results
when perhaps... the results werren't ?
The extraction papers/reports i've read - as per copper - it's a real bugger...
tough to detect - and sometimes - other acids are needed to - place int osolution
float and extract.
If the copper values are - rich in the rocks - but not in the soils/talus...
One would have ot ask why not the same ?
Could it be... the places - one chose to sample were too dilutive ?
Perhaps...
But.. i would like ot see a second sampling of the talus' copper showing.
Using a - fortified acid method - that tests for all transitional coppers.
Just incase - the former copper talus tests were off.
Copper is seen in the rocks in 3 forms...
chalcopyrite
azurite
malachite
if therer's iron, there could be cupric copper.
now... i could get real - jiggy - and suggest.. is there another form of copper
that no one has ever detected - such as a transitional copper that bonds to another mineral ?
Before you laugh... think again... copper can be seen in gold. Throw in salt metal bonding, and who knows how far minerals can go when bonding. ( tribonding / quadbonding )
which is why...
all avenues must be thought of, when seeking out where a copper could hide.
what if the lab, only detects the ionic charge value of a copper ?
what if they're given a list of charge ion value - and only seek that specific copper ion ?
let's now ask...
= what if the copper hitched a ride on another mineral ?
= it would certainly have a highe rcharge value
= all because the copper bonded t oanother mineral.
= goes undetected on the merits of - only seeking specific charge value or molecular.
sorry to post again on the metrics...
but... it was bothering me...lol
