Vancouver, British Columbia – May 19, 2021 (Newsfile Corp.) (Investorideas.com Newswire) Ridgestone Mining Inc. (TSXV: RMI) (OTCQB: RIGMF) (FSE: 4U5) (“Ridgestone”) is pleased to announce it has completed another phase of exploration at its wholly-owned Rebeico project in Mexico. The program, which was previously announced on April 13th, 2021, was comprised of geologic mapping, prospecting and sampling with assays expected in the coming weeks. Work to date has been positive and continues to suggest that the identified surface copper-gold mineralization on the Rebeico claims may be related to a much larger unexposed subsurface mineralized system.
Exploration Program Highlights:
- The program included detailed geological mapping, prospecting and sampling around the past producing El Cobre copper mine, in addition to all significant chargeability and resistivity anomalies (‘geophysical anomalies’) identified from the 2018/2019 IP surveys which covered the New Year Zone, Elena Concession, and other significant mineralized areas.
- A total of 93 samples were collected with assays anticipated in the coming two to six weeks.
El Cobre Mine
A total of fourteen (14) samples were taken from the main mineralized structure and historical dumps, and detailed geological mapping of the surrounding area was undertaken. The main mineralized structure is oriented north-south with a dip of 50 degrees to the east, varying in thickness from one to three metres. The system is characterized as a high sulfidation vein system, strongly oxidized on surface, with quartz veinlets with chalcopyrite, molybdenite, and pyrite. Historical samples taken in 1960 by the National Nuclear Energy Commission (Comision Nacional de Energia Atomica) reported copper grades from sampling of underground workings of 0.34%, 1.10%, 3.21%, 5.28%, 6.12%, 9.58%; and molybdenum values of 0.002%, 0.16%, 1.57%, and 1.58%. Additionally, a recent radiometric survey conducted by the Mexican Geological Survey over the area, indicated elevated potassium levels. Approximately four kilometres east of the El Cobre workings, a prominent, highly oxidized and altered gossan measuring 200 by 250 metres was mapped and twenty (20) rock-chip samples taken. Taking a global view of these positive occurrences on the Rebeico claims, these mineralized occurrences are related and may support the hypothesis that the source is a porphyry system being present below the surface.
Regional Geophysical Anomalies
A detailed mapping and sampling program was conducted over a 5.25 square kilometre area, focusing on geophysical anomalies identified by past surveys. In 2018 and 2019 the Company completed 31 line-kilometres of Induced Polarization/ Resistivity surveys covering an area of approximately 9 sq kilometres. The surveys outlined a significant chargeability anomaly over an 800 metre by 1,200 metre area with depths ranging from near surface to 300 metres. The Alaska Vein, the mineralized New Year Breccia Zone and artisanal Elena copper workings all occur within the surveyed area. A total of eighteen distinct geophysical anomalies were identified for follow up on the current program, which were mapped and a total of 62 samples were collected. Over the majority of targets, significant mineralization was identified on surface. Taken in a regional context, with the presence of high sulfidation copper bearing veins, mineralized breccias that are interpreted as diatreme breccias and in conjunction with surface geochemistry and historical records, RMI finds that this may be evidence that the source may be a sub-surface porphyry-type system that is responsible for the numerous mineralized occurrences encountered in the project area.
