A gemstone/specimen occurrence located near the California Gem Mine (Dallas Gem Mine), placing it S of Santa Rita Peak, on/near the San Benito River headwaters area.

NOTE: This is NOT the original Junnila Mine, that is now the Yellow Cat Mine, several miles N of this locality. The Yellow Cat is the locality of the andradite-topazolite specimens as described by Dunn.
