It appears that the 30,000 oz. is the gold content stacked in Q2. I recall something in Q2 production numbers that seemed to indicate that they intentionally held back on producing that gold in Q2 so that they had a head start for Q3 production. They are simply managing to their expectations. The 94K they produced in H1 translates into over 230K for the year using the 40:60 split (H1:H2). Here's my Q3 production estimates:
Twangiza - 34,000 oz.
Namoya - 32,500 oz.
TOTAL - 66,500 oz.
Q3 will be their best quarter this year. Q4 will be slightly less as they will not have the advantage of the additional gold content stacked they had going into Q3. Total year should come in around 225K oz.
