re: great news I'm guessimating that the specific gravity (SG) of Teena ore will most likely be around 3.1 gm/cc

Example Intervals:
TNDD009: 16.2m @ 14.91% Zn and 2.32% Pb
TNDD010: 12.5m @ 16.8% Zn and 2.68% Pb

Assume Zn and Pb is 100% Sphalerite and Galena,
*Sphalerite is 64 weight % Zinc and has a SG of 4.1 gm/cc
*Galena is 86.6 weight % Pb and has a SG of 7.4 gm/cc
*Host rock SG of 2.6 gm/cc higher due to the presence of pyrite

So in TNDD009, we have 16.2m @ 23.3% Sphalerite and 2.7% Galena. SG of interval should be (23.3% x 4.1) + (2.7% x 7.4) + (74% x 2.6) = 3.1 gm/cc

and for TNDD010, 12.5m @ 26% Sphalerite and 3.1% Galena. SG of interval should be (26% x 4.1)+(3.1% x 7.4) + (70.7% x 2.6)= 3.1 gm/cc

Aksier, might get a bit more tonnes with SG of 3.1 :)
