ABSTRACT:Vancouver, British Columbia--(Newsfile Corp. - January 4, 2019) - American CuMo Mining Corporation (TSXV: MLY) (OTC Pink: MLYCF) ("CuMoCo" or the "Company") announces that it has completed its review of all the information gathered during the 2017 drill program conducted at its Calida Gold project. As a result of the Company's assay detailed verification program, it was discovered that there was high variability between individual assays, especially for silver. Also, several assays indicated no precious metals present within the sample where samples were within 20 feet of previous historical samples containing precious metals. As a result of these discrepancies, upon completion of the drill program and the receipt of all assays, including checks and duplicates, the Company submitted seven core samples for microscopic analysis to Vancouver Petrographics Ltd of Langley, BC. The results of the analysis indicate two major point The Company has determined that the assay variation was due to a "nugget effect" created by the irregular distribution of the precious metal grains in the samples, such that taking a standard 50-gm assay split from 8 to 15 kg samples was not representative of the precious metal (Au and Ag) contained in the sample. Also, it should be noted that the results revealed that this is a fine-grained effect, and therefore standard techniques, such as metallic assays, are not applicable
