RE:RE:News..Deepest Drill Hits Bonanza Gold at AdumbiBonanza grade is defined as grade X intersect length greater than 100 gms
Grades increase with depth below the open pit, which is what we are seeing here.
At Kibali, drilling is down to 751 m and the underground grades at twice those of the open pit.
Latest resource levels showed 14.7 million in the underground and 3.1 m ounces in the open pit, a UG/ OP ratio greater than 4 .
Such a ratio would place the undeground of Adumbi over 10 million ounces..
How much longer will Barraik wait ?
