RIDGESTONE MINING COMPLETES IP SURVEY ON THE REBEICO GOLD-COPPER PROJECT, SONORA MEXICO

Ridgestone Mining Inc. has completed an induced polarization (IP) geophysical survey on its Rebeico gold-copper project, Sonora, Mexico.

The survey, conducted by Zonge International, of Tucson, Ariz., was undertaken to better define targets for a planned drill program. It comprised nine lines of IP, each 2.0 kilometres long for a total of 18 line kilometres, spaced 200 metres apart, covering an area of 1.6 by 2.0 kilometres. The company will be releasing the results of the survey in due course as such results become available.

About the Rebeico gold-copper project

The Rebeico gold-copper project is located approximately 115 kilometres east of Hermosillo, Sonora, Mexico, in the famed Sierra Madre gold belt estimated to have 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-per-cent interest in the Rebeico gold-copper project (subject to a 2-per-cent net smelter return (NSR)) from YQ Gold de Mexico S. de R.L. de C.V. (a private Mexican company), 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 1930s, with most of the efforts concentrated on the one-kilometre-long Alaska vein, where extensive underground workings reached depths of up to 70 metres.

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.

Additional information on the Rebeico gold-copper project can be found in the National Instrument 43-101 technical report entitled, "Technical Report on the Rebeico Gold-Copper Project, Central Sonora, Mexico," by Steven I. Weiss, Phd, CPG, of Mine Development Associates, dated April 25, 2018, which has been filed on SEDAR.

Technical aspects of this news release have been reviewed and approved by Derrick Strickland, PGeo, a qualified person under NI 43-101.
