(TSXV: RMI) (OTCQB: RIGMF) (\"Ridgestone Mining\") is pleased to provide a review of results from exploration on its Rebeico gold-copper project, Sonora, Mexico.After optioning the project in April 2018, the Company commissioned Steven Weiss, PhD., CPG, of Mine Development Associates (MDA), Reno, Nevada, to prepare a NI 43-101 Technical Report on the project, which was completed on April 25th, 2018.The report makes reference to two styles of mineralization recognized on the Rebeico property, both containing copper, gold and silver: the over one kilometre-long north-south trending Alaska vein, and the intensely altered breccia zones southwest of the vein.Both styles of mineralization contain similar minor elements such as bismuth, suggesting that they are related to each other and may be close to a possible copper-gold porphyry at depth.To further investigate this possibility, the author recommended a Phase 1 exploration program consisting of an induced potential and resistivity survey, mapping and rock-chip geochemical sampling, and diamond drilling.An Induced Polarization (IP) geophysical survey, comprised of 18 line-kilometres, was carried out in 2018 by Zonge International of Tucson, Arizona. The IP survey consisted of nine east-west lines at 200 metre spacing by two kilometres in length. In a preliminary interpretation of data obtained from the survey, Zonge observed a high chargeability anomaly which begins to be evident below where the mineralized breccia zone is observed on surface. Here, the anomaly appears at a depth of between 200 to 300 meters and progressively increases in size and intensity towards the last survey line, 600 meters to the south, remaining open.Zonge also noted that the top of the zone of high chargeability appeared to decrease in depth going south and could reach surface near the Company's Elena mining concession. Subsequent field investigations in the Elena concession encountered several mineralized outcrops, some of which were sampled. The rock chip samples were submitted for analysis and the assay results are reported here:Sample IDWidth(m)Cu (%)Au(g/t)Ag(g/t)E11.00.9850.0236.6E21.20.0160.010< 0.5E31.00.3100.0707.4E40.60...
