This is a little OT, but in line with a subject Bud in Denver brought up here some days ago.
"TORONTO, Sept. 16, 2014 -- Electric car producer Tesla Motors is planning to build a $6-billion lithium-ion battery 'Gigafactory' in 2017, doubling the 2013 global output of lithium ion batteries and creating a massive shortage of graphite – unless new mines come on line." [Emphsis added.]

Among the most related minerals are copper, silver, gold, zinc, which we have at Hay Mountain. However, I think there is only one producer of graphite in North America at this time and that's in Canada.
There are, however, a number of prospects near Hay Mountain in the Dos Cabezas area (http://www.mindat.org/minlocsearch.php?frm_id=mls&cform_is_valid=1&cf_mls_page=1&minname=graphite®ion=Dos+Cabezas)
...and I found one at Bisbee (http://www.mindat.org/minlocsearch.php?frm_id=mls&cform_is_valid=1&cf_mls_page=1&minname=graphite®ion=bisbee&sort=&submit_mls=Search).
Having mentioned these, I have no idea how active these claims may be.
This is not to suggest that any of them are economic, or that graphite in any amount will be found at Hay Mountain, but this does a some minor additional interest to the area.
