There are also sections of mineralization that "cross fault" and run across both trend lines that have been drilled over a distance of 150 meters and 100 meters.
There is also a third and much smaller parallel zone located between the two main zones that has been drilled over a strike length of 200 meters.
All of these targets represent extended near surface tonnage that exhibits on surface mineralized tonnage available for potential extraction. IMHO
Assuming that these targets total 450 meters of strike and width of 30 meters. We have an additional 30m x 450m x 170m depth for an extra 6.4 million tonnes NOT included in your guesstimate.
Warning this is a guesstimate and IMHO the JORC will be around 15 million tonnes which is a remarkable achievement in 6 months (and is referred to in the German TV interview) and should put BGS at +$1.00 per share.
