Located 2.7 km west of Huanacaxtle, the Betty area is underlain by volcanic sandstone, pebble conglomerates and welded crystal lithic tuffs of the rhyodacite volcano-sedimentary sequence. Stream sediments of the three small drainage areas, that comprise the Betty prospect, returned values of 1,097 ppb to 1,341.3 ppb Au while the highest assayed value from a rock sample contained 158.6 ppb Au. The Betty area exhibits a broad zone of silicified, argillic altered intermediate tuffs with fracture controlled quartz-specularite veining. Grab samples of the alteration contained anomalous but uneconomic concentrations of Au, Cu and As. It is postulated that the exposure on the surface represents a lithocap related to buried mineralization. This hypothesis is supported by subtle polymetallic soil anomalies.
