Bonanza grade references in industry are typically for 100+gram/metre intersections. At that amount of metal it is likely to be economic if it is wide and low grade or narrow and high grade (to cover different deposit types). However, the size of the positive economic outcome will largely be determined by mining costs....so a narrow high grade is better due less significantly moved. Therefore ABU trumps IDC at present due to high grade, noting that both are shallow open pit starts. IDC results look a lot like ROL's from a couple of years ago. Some potential but expensive to start up.
