PHOENIX, AZ - JUNE 11, 2020

PHOENIX, AZ (June 11, 2020)  (GLOBE NEWSWIRE) -- Tombstone Exploration Corporation (OTCQB: TMBXF), a fully reporting U.S. based mining company, is pleased to announce in combination with Goldrock Resources Inc. and the Bonanza Mining Company that construction has begun on the leach pad at the Harquahala Mine in La Paz County, Arizona.

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 underground workings, from which some 180,000-200,000 ounces of gold were reportedly produced from high-grade ore in the late 1800's and early 1900’s. Mined rock and tailings from previous operations represent an additional potential resource.

Alan Brown states “Once the construction is complete, we will start moving an estimated 500,000 tons onto the leach pad and begin an estimated six to eight month processing period for all of the mined material in Phase One.  Once leaching has started, bi-weekly delivery of the carbon to our designated gold processing facility is expected.  Based on past metallurgical testing, production is budgeted at 23,000 ounces of gold with potential for more.  "We are highly confident in our test results and expect our first gold pour in mid to late September," stated Bonanza Manager Todd Fayram.

Todd Fayram, Bonanza Project Manager, is a Metallurgical Engineer with 26 years of experience with global assignments and extensive experience in mining, crushing, mineral processing and mineral economics. Mr. Fayram states “ The entire site has been surveyed and stacked for location. A drone has flown the site and created a 3D model of the site to 6" contours. 5D started site mobilization on 6/8/2020 and 5D has mobilized a D7 CAT and Small Track Hoe. 5D has effectively grubbed and cleared 3/4 of the pad area”.
