RE: RFC AMBRIAN: COPPER M & A11 Apr 2021 22:47
News - "I have able to just locate the XTR Hole 1 details:
XTR Hole 1: 0. 3 % CU COPPER.
0. 0 2 g/t au gold
1.45 g/t Ag Silver.
= 0 . 3 3 % Cu EQ. [920m from 110m]"
Yes, you read a news release. A knighthood cannot be far away.
News - "So, in short, the CU is still 0 . 3% COPPER vs 0. 3 3 % Cu EQ.
So, a small variance only of equivalent which is NOT statistically significant?"
It's not a question of statistical significance or not. If you're a marginal project then that extra 10% potential revenue might be the difference between profit or loss, success or failure. We want the numbers to be higher, obviously. 0.3% and 0.33% is a relatively small difference, but here it just reflects a lack of gold. hmmmm.
News - "I quoted from RFC AMBRIAN:
WORLD RANKED NO 1: PEBBLE-ALASKA @ 0. 3 4 % CU [Copper]
WORLD RANKED NO 9: CASINO-CANADA @ 0. 1 7 % CU
WORLD RANKED NO 10: MASON - USA @ 0. 3 % CU"
Yes, and my problem with that is that all of those projects (especially the first two) have a much higher CuEq% than Cu%, so their Cu% in isolation is both meaningless and misleading. The CuEq% shows how much their rocks are worth in situ.
Pebble - 6.5 billion tons M&I of yes only 0.40% Cu, but it's 0.77%CuEq when you add in all of their gold, moly, silver, rhenium.
Casino - 2.2 billion tons M&I of yes only 0.16% Cu, but it's 0.36%Cueq when you add in the gold, moly and silver.
Mason - 2.2 billion tons of yes only 0.29% Cu, but it's roughly 0.35% CuEq when you add in the gold moly and silver.
Now i happen to think all three projects suck for one reason or another, and it's easy to find better prospects in other companies. But anyhow, when aiming for an apples to apples comparison, you're best to measure by CuEq because porphyries usually contain good amounts of payable gold, mo, ag etc.... Or at least the good ones do! ;-)
