Mineralization Comments

Oct 05, 2010 (A Wilson) - The garnets are pale red and average about pea size. They occur in zones but there are several rich bands 6-10 feet wide containing garnets up to 2 inches in size. The largest garnets are hosted within the mica schist. The garnet was deemed to have good abrasive qualities and easily mined and concentrated.
