Let the numbers speak.I assume the 19k ounces of last quarter to be 5k +7k +7k. July was wet season and had the mill problems.
If the Smarts ore gets replaced with 0.7 g/t lower grade Hicks ore and Smarts ore was 60% we should expect 6k * 3 ounces if no mill problems. Maybe they have pockets of higher grade ore in the stockpiles and can mitigate the impact by blending, maybe not. Expect 17.5-18k for December quarter and $80-$90 higher AISC would by my rough estimate.
