Like all things in life you need to read the fine print and footnotes. Within the 15.3 m @8.12 g/tonne was section of 4.8 m @ 15.67 g/tonne. A glory hole? no. But the results still probably support a mineable deposit. The majors have their breakeven g/tonne in mind at some $/troy oz (certainly it is not today's price). The fact that it is further west (1 kilometer to go to Lake Shore) is very encouraging as is the fact that they have not reached the bottom of the deposit or the outer edges .
BTW According to my table of conversion factors: 1 Tonne = 1 Ton = 2240 pounds; 1 gram = 0.0353 ounce (on the postage/kitchen scale) = 0.0322 troy ounces; 1 ounce = 0.9115 troy ounces
