September 6, 2017 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”) (TSX-V: RRI), is pleased to report that geologic mapping and rock-chip sampling continues at the partner-funded Glor Gold Project (the “Project”) in northwestern Sonora, Mexico. This latest phase of exploration work has yielded further encouraging results from the Puerto El Alamo (“Alamo”) target area in the central part of the Project. Recently received gold assays for a batch of 75 rock-chip samples from the Alamo target area include high-grade values of 14.4 and 24.0 g/t Au. The current exploration campaign at Glor is being funded by Centerra Gold Inc. (“Centerra”), with the ultimate objective being to discover an economic deposit of orogenic gold mineralization similar to that found at Alamos Gold’s El Chanate Mine located approximately 12 kilometres to the east-southeast of Glor.
The Alamo target area is located 3 kilometres southwest of the Pitaya target where Centerra recently drilled 9 diamond drill holes (1,942 meters) completed under the JV. These drill-holes tested a zone of disseminated and fracture-controlled gold mineralization hosted by andesitic volcanic rock that had been sampled in excavated trenches (see Company news releases issued on April 17 and June 19 of 2017). Geologic mapping of the Alamo target area has outlined extensive outcroppings of andesite volcanic rock similar to that found at Pitaya (see Figure 1, below) and a number of shear structures inclined at low angles to the south have been identified within the volcanic unit and in underlying sedimentary rocks. These ductile fault zones display orogenic-style rock alteration, quartz and carbonate veining and have yielded rock-chip samples that assayed up to 14.4 g/t gold across 1.0 meter. In addition, the Alamo target area is host to a number of quartz veins, typically tens of meters in length and less than 30 centimetres thick containing samples which have yielded gold grades of up to 24 g/t Au.
