Second Pour With Substantial Increase From Production At Bonanza Harquahala Mine

PHOENIX, AZ – Tombstone Exploration Corporation reported that 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 in July. 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 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 it continues 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, President & CEO, said, “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.”
