Ridgestone Commences Exploration at Its High-Grade Rebeico Copper-Gold Project in Mexico

Vancouver, April 13, 2021 - Ridgestone Mining Inc. (TSXV: RMI) (OTCQB: RIGMF) (FSE:4U5) ("Ridgestone") is pleased to announce a phased exploration plan at it's wholly-owned Rebeico project in Mexico. Work to date has been positive and indicates that the identified copper-gold mineralization on the Rebeico claims may be part of a much larger mineralized system and is most likely related to this system.

The current exploration phase will be comprised of geologic mapping, sampling and prospecting with the aim of delineating additional targets for follow-up exploration drilling. Specifically, the program will focus on the New Year Zone, the Santa Elena outcrop, and the El Cobre mine. In addition, the program will evaluate a number of copper and gold prospects identified on the project.

"We are excited to remobilize to the Rebeico project specifically given the significant past exploration efforts which have already delineated a number of high-grade copper and gold opportunities within the expansive property package," stated Jonathan George, Ridgestone's CEO and Director. "Our focus of this next phase of exploration is to refine and prioritize the numerous copper and gold targets within the project area for a follow-up drill program and extend the areas of known mineralization."

New Year Zone
Exploration efforts at the New Year Zone will follow up on the successful 2020 exploration program, which outlined a large zone of widespread copper and gold mineralization with rock chip sampling returning up to 0.65% copper and 12.95 g/t gold. The subsequent drill program confirmed the sub-surface extension of widespread mineralization identified on surface, with highlights including 1.56% copper plus 1.8 g/t gold over 19.30 metres from surface and 0.54% copper over 29.15 metres from surface. Based on geological interpretations of past exploration data, the Company will focus follow-up exploration to the east and north-east where mineralization is expected to be more pervasive.

Elena Concession
Previous rock-chip samples from the Elena concession returned assays of 3.77% copper over 1.5 metres and 3.42% copper over 1.5 metres, where artisanal workings are observed in a stockwork/breccia zone with abundant copper oxides. The Elena concession is underlain by an intense chargeability anomaly, which may represent a potential source of the copper mineralization observed at surface. Approximately 450 meters west of Elena, three rock-chip samples collected from outcrop returned from 1.31% to 2.13% copper suggesting a possible extension of the mineralized zone. Additionally, approximately 600 metres north of Elena, channel samples collected from outcrop returned 2.42% copper and 4.35% copper over a 1.5 metre interval.

El Cobre Mine
The El Cobre mine was a high-grade underground copper mine operated by Asarco during the 1960's. Based on historical records, the mine was developed on three levels down to a depth of 130 metres with over 180 metres of lateral development on each level. Historical sampling of waste material discarded from prior operations ranged between 2.07% to 2.41% copper with notable gold, silver and molybdenum credits. The current exploration program will focus on prospecting around the El Cobre mine and surrounding area for extensions to the high-grade copper mineralization and delineating targets for follow-up drill testing.

Regional Exploration
The Company's wholly-owned 3,459-hectare land position that comprises the Rebeico property has seen little to no modern-day exploration. The exploration program will focus on following up on a number of high-grade artisanal workings documented by Mexican Government reports and the Mexican Geological Survey (Servicio Geológico Mexicano or "SGM").

The Company has engaged Prospeccion y Desarrollo Minero del Norte S.A. de C.V. or ProDeMin of Mexico to assist with the exploration efforts. ProDeMin engages primarily in project management, in addition to exploration efforts such as geological mapping and sampling, surveying, prospecting and project generation. ProDeMin's clients include senior gold companies such as Kinross Gold, Argonaut Gold, and Alio Gold, as well a number of Mexican-focused exploration companies.
