I know you are not asking me, but I thought the figure was slightly higher than that, 22 or 23 percent.

Anyway, and from reading history of mining at Tombstone, I think silver grades improved with depth, so if there is associated silver with the iron and malachite showings at Hay Mountain, it could get better with depth there too.

By the way, when the mines flooded at Tombstone, the grades had been improving with depth, so it was a no brainer to bring in (then) new age, massive pumps at great expense. However, once mining resumed in these rich grades, they quickly ended, and Tombstone died a second time.

Recall here the Walnut Creek claims adjacent to downtown Tombstone? I think this is a silver target not previously drilled or cut by tunnels. Sorry, this should be a subject for another time. ...wife hogging the TV for now.
