Benta Group, in Sees. 20 and 29, T. 18 S., R. 12 E., M. D. M., waslocated in 1913 by M. G. Ramirez and S. Tirado, of Hernandez. Thereare two claims in the group, which joins the Ramirez or Los Picachosclaims on the southwest. The claims are on the same series of highlysiliceous croppings which show so prominently on the Ramirez prop-erty, but the serpentine appears less silieified. Only the annual assess-ment work has been done so far. A little cinnabar has been found,occurring in veinlets with silica in the serpentine fractures. It is inthe Monterey National Forest, reached only by trail. Bibl.: Cal. State ]\Iin. Bur., Report XV. p. 652; Chapter period, 1915-1916, p. 58. Bonanza Group.
