just 1 of these quads-I think 69,70,72,73 (see bingos post I just reposted) gave a proven 13,400,000 tons,and as I said the quad was only ca 8.7% of the Coloso length as per my calcs.and they didnt drill to bottom of iron-bottom would probably need beneficiation-which China is very familiar with,as China's ore averages 15% and falling as per posted articles, w Chinese mines as low as 4% underground (documentary I saw). FIgures might have to be ameliorated a little as some of this may be where the Samson and Coloso veins bordered each other though it was "upstream" where they crossed.
I still dont know how they determined the so far known 2 veins on the S 1/2 of Baja 14 (S of San Vicente River) when I think all 73 drill holes were on N 1/2 of Baja 14-maybe bingo knows.
