(TSXV: RMI) (OTCQB: RIGMF) (\"Ridgestone Mining\") is pleased to announce the results from a bulk sampling program recently carried out at its Rebeico gold-copper project in Sonora, Mexico. A total of 111 samples with a combined weight of approximately 2,500 kilograms was collected from eight waste-rock dumps remaining from historical underground mining on the property. The waste-rock material was mined principally from the \"Alaska\" vein as recently as the 1960's.The waste-rock dump samples, averaging approximately 22 kilograms each, were collected from trenches and holes excavated with pick and shovel, and were submitted to LABVAL, an independent commercial analytical and metallurgical testing laboratory in Hermosillo, Sonora. Each sample was assayed for gold, silver and copper. Gold and silver were determined by 30-gram fire-assay fusion with a gravimetric finish. Copper was analyzed by atomic absorption spectrometry following digestion with aqua regia. Summary assay results for each of the waste-rock dumps are shown in the following table:Waste Dump NameSamples (N)Sample Wt Mean (kg)Au Mean g/tAu Range (Min-Max) g/tAg Mean g/tAg Range (Min-Max) g/tCu Mean PercentCu Range (Min-Max) PercentVeta Grande2120.56.681.37-16.8512.670.83-84.150.790.28-1.72Upper Alaska2624.63.300.62-10.9410.784.00-25.301.390.65-2.50Lower Alaska1421.83.401.23-8.9323.1710.70-92.71.320.32-2.70La Verde818.73.541.27-8.9112.130.31-35.540.370.08-0.65Josefina721.60.240.14-0.5712.380.80-31.170.490.42-1.00Tunel de Garcia719.22.070.30-5.721.821.00-5.740.400.28-1.00Año Nuevo1325.91.010.29-2.225.131.00-17.700.600.23-1.32Elena1521.00.100.04-0.585.280.20-17.270.990.18-2.10Totals11121.72.510.40.8 Erwin Wong, CFO and Director of Ridgestone Mining, commented: \"While these sampling results represent material that was uneconomic at the time, we are highly encouraged by the grades presented in the context of today's metal price environment. The sampling results serve to reaffirm the historical mining records and moreover, the potential mineralization hosted by the Alaska and associated veins. Going forward, we are incorporating the bulk sample results in addition to the results f...
