There's more like this.

From NR 180 - "These replacement deposits are expected to be quite high grade and may be located surrounding intrusive porphyry perhaps carrying disseminated mineralization of bulk minable grade."

From NR 174 - "We have now compared the footprint of the Mission-Pima ore bodies to the magnetic anomaly high at Hay Mountain, electromagnetic anomalies and the nested geochemical anomalies. The footprint (horizontal or map projection) of the Mission-Pima ore body fits comfortably in the superimposed anomalies at Hay Mountain. Similarly, the footprint of both Bisbee, Arizona, and Bingham Canyon, Utah, also fit comfortably within the anomaly highs at Hay Mountain."

...and we have 8 targets in the Tombstone Caldera. Hay Mountain is but one!
