Vancouver, British Columbia--(Newsfile Corp. - August 28, 2018) - Ridgestone Mining Inc. (TSXV: RMI) (the "Company" or "Ridgestone), is pleased to announce that drilling is underway at its Rebeico Gold-Copper project located in Sonora, Mexico

The program is designed to test for gold and copper mineralization below historical workings along the "Alaska" vein which has a strike length of over one kilometer and is open at depth.

Diamond drilling will comprise 12 HQ-diameter holes totaling approximately 1,400 meters, and is being conducted by Layne Drilling of Mexico, under the supervision of YQ Gold de Mexico, the project operator.

About the Rebeico Gold-Copper Project

The Rebeico Gold-Copper Project is located approximately 115 kilometers east of Hermosillo, Sonora, Mexico in the famed Sierra Madre Gold Belt, which has reportedly produced more than 80 million ounces of gold and over 4.5 billion ounces of silver.

Ridgestone has an option to earn a 100% interest in the Rebeico Gold-Copper Project (subject to a 2% NSR) from YQ Gold de Mexico S.de R.L. de C.V., (a private Mexican company) ("YQ") as further described in the Company's June 11, 2018 news release.

The Rebeico Gold-Copper Project's mineral concessions cover approximately 167 hectares located on private land and are easily accessed by paved highway and all weather gravel roads.

The Rebeico Gold-Copper Project has had intermittent historical production since the 1930's, with most of the efforts concentrated on the one kilometer-long "Alaska" vein, where underground workings reached depths of up to 70 meters.

Sampling by YQ geologists and others demonstrates that portions of the Alaska vein and some outcrops of a breccia zone west of the vein are mineralized with gold, silver and copper at concentrations that justify extensive exploration work, including drilling.
