A few have commented many times over on here on this topic and depth by itself is not the issue. But because the tenor (metals in 100% sulphides) is moderate, you really need either 1) what they have found and continue to find, i.e. smallish pods, to be close to the surface, lets say within the arbitrary 200m; 2) the resource to be much much larger, or 3) similar size deposits but an major increase in grade/massive sulphide thickness. This is exploration. Not many companies hit the jackpot with their first holes at their first prospect. Azure appear to have found a system that has the ability to produce a deposit, it's just needle in the haystack exploration and punters need to have patience.
