43-101 / JORC Explanation received - In -Box ,.thanx . open to board discussion,
Hello Traps.
Just wanted to check you numbers in privacy here.
I could be wrong, but since core is not consistent on density, I would not convert it's volume directly into mass. What I think is more accurate is to convert your volume into copper volume (use whatever % you pick, I tend to use 1% for 4100N to be very conservative but 3% is great as well). Once you do this, you have the amount of copper by volume in that section. We know the density of copper accurately and then you can covert that volume to mass. We also know the price of copper per unit mass.
If I am accurate, I think there may be an error in you posted calculation, but I could be wrong. I thought better reach to you in private, we are on the same team here.
have a great weekend.
MY POST,
The current drilling here at 4100 zone IN-FILLING between the 17 historic holes so-far has seen 9 new holes sent out to the Lab..The area so-far here at 4100 zone has copper continuity over one kilometer by 400 meters and avg. over 33 m thick of 3 % copper per ton..
Back of napkin #### 3000 X 1200 = 3,600,000 SQ FEET
3,600,000 X 100 = 360,000,000 CUBIC FEET
360,000,000 cubic ft div by 12 = 30,000,000 tons
30,000,000 tons at 3 % copper.
..One Ton = 60 pounds of copper
30,000,000 tons x 60 pounds = 1.8ep pounds
1.8ep div by 2000 pounds = 900,000 tons of copper
900,000 tns x $ 6,000 per tn = $ 5.4 Billion..
Explanation
In my calculation - back of cuff
I agree we don"t know the density factor, which well change my calculation substantially. Afactor of 40 would cut the volume mass of copper and also a more fair average of 1 % would pass..
I used the LAB results in my calculation as being 3 % copper per ton. One ton equals 2000 pounds so 3 % = 60 pounds per ton..
Here i used 12 cubic feet in physical size being = to one ton which one ton contains 60 pounds of copper.
Yes a 1 % cu/tn = 20 pounds per tn,
Volume over Mass of cu..???
Thanx,. for in-box
