Tombstone Exploration Corporation announced the results of the processed and refined ore from Metalor USA that was shipped from the Bonanza Harquahala Mine on April 7, 2022. This is the second delivery of precious metals in 2022 and the third shipment will be sent on May 3, 2022. The results of the processed material from April 7, 2022 produced 456.80 oz of dore which delivered 83.34 oz of Au and 78.66 oz of Ag.

The leach has been running 24/7 and continues as crushed rock and leach material are loaded onto the pad. The third shipment for processing the carbon and refining the gold and silver ore for 2022 is expected to be shipped on May 3, 2022. The Bonanza Mine property includes the Harquahala and Golden Eagle mines, located approximately eight miles south of Salome, Arizona.

The project totals 2,656 acres and has significant potential for gold and silver production in multiple phases moving forward. The Bonanza Mine is located where the Prolific Walker Lane and the Sonoran Geosyncline overlap with likely extensions of Carlin Trend and Mesquite-style mineralization generating Arizona's biggest richest deposits.
