Thank you for the prompt and detailed reponse, and for thinking the answer important enough to share on the company Web site.

Your reply reminded me that the simple answer I thought I may read here could well be complicated by the fact that the surficial, in-line blebs/veins of iron and copper-related minerals at Hay Mountain have been forced through 100-200 feet of brecciated marble, that the economic minerals we seek below this capping may have structures different from what is exposed on top.  And this may well be the case.

I asked because I recently learned that where bornite is abundant in a porphyry, gold recoveries can be better than at other such structures.  As you have already indicated that Hay Mountain is a sprospective copper-gold-moly deposit, I was wondering how bornite could play a part in this. 

We will know better from drilling, of course.

Thanks again.
