I have a question about BDR's AISC figures. The latest announcement has AISC of $US$638 for Q2 (ended 31/12/2014). This is a tad above the forecast range of US$595-615 quoted by BDR on 2/1/2015, but still an excellent figure.

The ASIC figure announced earlier by BDR for Q1 (ended 30/9/2014) was US$1150, so there has been a major improvement in this latest quarter. What I now find confusing is that in this latest announcement the projected AISC for the full CY2015 is US$810-890. That looks like BDR is going backwards - an increase in AISC of US$200 across the whole year. As Prof. Sumner-Miller would say "why is this so?"

I continue to watch BDR - am not a holder but have been looking to buy if there is a noticeable price weakness, but ---- I do find the company very confusing. My gold stock at present is NST.
