American CuMo Mining Updates Shareholders

Vancouver, British Columbia--(Newsfile Corp. - April 25, 2018) - American CuMo Mining Corporation (TSXV: MLY) (OTC Pink: MLYCF) ("CuMoCo" or the "Company") announces that it has completed its analysis of the current status of the CuMo Project and based on the results of the recently announced updated Preliminary Economic Analysis has outlined a drill program for the upcoming field season. The Company plans to drill up to nine holes on the west side of the deposit with drill pads located on the recently purchased private land. The holes are designed to examine the extent of the higher-grade copper and silver mineralization between hole 10-47 and the Coon Dog waste dumps, first announced in the Company's November 20, 2017 news release. The waste dumps are located 1371 meters (4500 feet) west of Hole 10-47. Hole 47 intersected 301 meters grading 0.22% Cu,5.35 gms Ag/T and 0.054% MoS2. The dump grab sample indicated it is part of an older copper porphyry system that pre-dates the molybdenum system at CuMo. A 15-kilogram sample from the dump assayed 3.12% Cu, 783 gms Ag/t, and 0.986 gms Au/t.

The reader is cautioned that grab sample assays represent prospecting samples and may not be representative of the grade or width of the mineralization. There is presently insufficient data with respect to the size and extent of the mineralization represented by the sample to determine its significance. The proposed drilling is designed to determine that significance.

At Calida, a large 8-kilogram sample from one of the better intersections of the 2017 drilling has been delivered to PMC Ltd. of Maple Ridge. PMC will perform a full in-situ mineral composition and precious metal deportment analysis using a scanning electron microscope fitted with an energy dispersive spectrometer to determine the true grade of the sample. Analysis will be on the entire sample, not the regular 50-gram assay samples used at commercial laboratories.

Company management has accepted an invitation to participate in the "Mining Pitch Battle", based on the Sharks Tank and Dragon's Den TV programmes, at the Mines and Money conference in New York City during May 8^th and 9^th. Management will be attending the conference following investor presentation trips to Munich, Germany, and Zurich, Switzerland, during the week of April 30 to May 4, 2018.

The Company announces that it has granted as of April 20, 2018, a total of 6,975,000 new stock options to directors, officers, and consultants. The options granted are for five years expiring on April 20, 2023, at a price of fifteen cents ($0.15).

Finally, the Company announces that materials for the upcoming Annual General Meeting (AGM) on Wednesday, May 30, 2018, at 10 am PST at Suite 2300-550 Burrard Street, Bentall 5, Vancouver, British Columbia are being mailed and are also available on the website (http://cumoco.com/investors/annual-special-general-meeting/).
