(TSXV: NIM) (the \"Company\" or \"Nicola\") is pleased to announce the results of a preliminary metallurgical testing program and the significance of a copper-magnetite grade equivalent (\"CuEq\") at its wholly-owned New Craigmont Project (the \"Project\"), located 14 km from the city of Merritt, BC.Nicola contracted ALS Metallurgy's Kamloops[1] laboratory to perform magnetic separation and froth floatation testing on samples collected from a number of selected diamond drill and reverse circulation drill holes (\"RC\").A total of thirty-nine samples were classified into low-grade (\"LG\") copper and high-grade copper (\"HG\") composites that reflect mineralization grades encountered at the Project. The composites were tested using a Davis Tube[2] for magnetite separation. Composite samples were then tested by froth floatation to determine copper recovery. The tailings from the froth floatation was then re-tested using the Davis Tube test to determine the iron (\"Fe\") recovery after copper extraction (Figure 1).Figure 1: Workflow of composite samples[1]To view an enhanced version of this graphic, please visit:https://orders.newsfilecorp.com/files/4873/42897_1acf4d2624585933_001full.jpgMetallurgical testing was conducted to provide a CuEq value, based on recoverable magnetite (Fe₃O₄) associated with Cu mineralization, as not all Fe grades can be attributed to magnetite. ALS Metallurgy provided the Company its findings in the Metallurgy Testing for Nicola Mining - KM8541 report[3], which is available on the Company's website[4] and filed on Sedar. The composite samples created are described below: Low-grade Copper Composite: Feed assays on the LG composite were conducted by ALS and returned grades of 0.27% Cu and 5.1% Fe. The presence of magnetite in low-grade material provided an economic contribution of approximately 34% and an increase in CuEq of approximately 0.09%.High-grade Copper Composite: Feed assays on the HG composite were conducted by ALS and returned grades of 3.26% copper (\"Cu\") and 11.4% iron (\"Fe\"). The presence of magnetite in high-grade material provided an economic contribution of ...
