I believe I'm nitpicking but I've found several instances of "frontal lodes." Some articles which use "lodes" go on, later in the article and use "lobes," so I assume these are simple typos. Other articles use "lodes" several time and never even hint that they have uncovered a source of gold in the human cranial region.
With gold at $1800 per ounce is my head worth(oops) more to me than I can Possibly imagine?;)
