Ridgestone Commenced Permitting for Drill Programs at Both Mexican Projects

Vancouver, May 25, 2021 - Ridgestone Mining Inc. (TSXV: RMI) (OTCQB: RIGMF) (FSE:4U5) ("Ridgestone" or the "Company") is pleased to announce it has commenced permitting for drill programs at both projects in Mexico: the Guadalupe y Calvo (GyC) gold-silver project in Chihuahua State and the Rebeico copper-gold project in Sonora State. The Company is planning for drilling to commence in the late summer following the end of the local rainy season.

"We are excited to advance both projects to allow for drilling later this year," commented Jonathan George, CEO. "The maiden resource tabled for our GyC gold-silver project represents the beginning of a much larger story for the Company. At Rebeico, we are highly encouraged by the preliminary results from the recently-completed exploration program and look to announce assay results in the coming weeks. Our team has identified a number of highly-prospective new target areas, including the past-producing El Cobre copper mine, which has seen little to no modern-day exploration."

Guadalupe y Calvo (GyC) Gold-Silver

Drilling at GyC is designed to further the recently-released maiden resource for the project. The current resource area, which stands at 356,000 oz AuEq in Indicated plus 460,000 oz AuEq in Inferred, remains open for expansion both along strike and at depth. Drilling will look to further define the high-grades at the Rosario and Nankin veins, in addition to testing for significant extensions within the district.

Rebeico Copper-Gold

The Company is permitting for a drill program to test the high-priority copper target areas that were the subject of a recently-completed exploration program. Assay results are anticipated in the coming weeks, which will serve to prioritize the numerous target areas being permitted.
