Production Has Started At The Bonanza Harquahala Mine


PHOENIX, AZ - Tombstone Exploration Corporation announced first results have been received from production in June that started at the Bonanza Harquahala Mine. Production of 83.7 oz of Dore was stripped from the Bonanza’s activated carbon by Metals Research and sent to Metalore Inc. for final disposition. This is a milestone event with improvement in production expected as the project continues to move 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.

Alan Brown, President & CEO, said, “This is the start of production after a series of issues related to the water and permitting. 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. Bonanza will continue to move forward with production with ounce production expected to increase as we perfect the leach process over the upcoming months. As the leaching has started, periodic delivery of the carbon to the designated gold processing facility is expected.”
