Ann: More High Grade Zinc Intersected at Oposura, page-4

I was interested in that they increased the number of holes from 120 to 160 and so added two months of effort and costs. Why? Infill drilling to better define the resource or looking for extensions where the resource was open? Assuming the new holes are numbered 120 to 160, had a quick look at where they were located to get a sense of purpose but not conclusion. I did note however that there are just 18 new holes in the western zone so assume that balance off 22 are back in the east. Again, curious as to their purpose....
