Press Release


PHOENIX, AZ—AUGUST 20, 2021--(GLOBE NEWSWIRE)--Tombstone Exploration Corporation (OTCQB: TMBXF), a fully reporting U.S. based mining company, announced today in combination with Goldrock Resources Inc. and the Bonanza Mining Company the second pour from production.

Production of 262.59 oz of Dore was stripped from the Bonanza’s activated carbon by Metals Research and sent to Metalor USA Refining Corp. for final disposition. This is more than a 300% increase from the 83.7 oz of Dore from the first pour announced on July 13, 2021. Reaching another milestone event with the changes that we continue to make on the Bonanza Leach System, we improve production as the project moves forward.

The leaching commenced at the Bonanza Harquahala Mine on June 3, 2021, when pH levels increased to allow for safe sustained leaching. Approximately 35,000 tons of rock have been placed on the leach pad with the entire area under leach. Carbon has been placed in all four carbon columns and is collecting gold & silver from solution. As we continue to increase the production of gold, the Bonanza Mining Company will continue to stack and load the pad with an additional 465,000 tons of Crushed Rock.

Alan Brown, TMBXF President & CEO, commented, “We are excited and expect the numbers to continue to increase. The personnel at the mine continue to seek ways to improve production and identify better options for leaching and ultimately create more enhanced leaching characteristics. The price of gold remains stable and strong at the price $1,780/oz.”

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 & the Sonoran Geosyncline overlap, with likely extensions of Carlin Trend and Mesquite-style mineralization, generating Arizona’s biggest, richest gold deposits.
