Vancouver, B.C., May 7, 2013: American CuMo Mining Corporation (TSXV: MLY, OTCQX: MLYCF), (formerly Mosquito Consolidated Gold Mines Limited) (“CuMoCo”) is pleased to report excellent results from its 2012 diamond drilling program for its Idaho-based molybdenum/copper CuMo Project.

A total of 4,700 meters (15,463 feet) was drilled in nine (9) holes. Holes were located on the extremities of the deposit and as infill to improve resource confidence. The results confirmed the established geological model and also the excellent grade continuity of the mineralized zones. Hole locations are shown in figure 1 and detailed results are contained in table 1 attached.

Highlights from the drilling include:

The entire core from all holes was sampled and cut in half using a diamond saw with one-half sent for analysis while the other half has been kept and stored at the core facility located on site. Following cutting, the samples were delivered directly by CuMoCo personnel to either ALS Chemex or SGS Labs, both fully accredited analytical laboratories located in Elko, Nevada. They were first analyzed for 47 elements using a four (4) acid digestion with analysis by Inductively Coupled Argon Plasma Optical Mass Spectrometer (ICP-MS). Copper and Molybdenum bearing samples were then checked by using a larger five gram sample and analyzed using pressed powder pellet X-Ray Fluorescence Spectroscopy (XRF). In addition, duplicates, blanks, and standards were analyzed to ensure analytical accuracy and reproducibility. All rejects are being kept for further analysis and for use in metallurgical testing.

A full summary of the analytical results is outlined below in Table 1. Mineralization consists of copper, molybdenum, silver and rhenium. As a result of the multi-element nature of the mineralization, it was decided to calculate both a copper and molybdenum equivalent for the intercepts. Both equivalents are required as the deposit is zoned as described above. Please see notes below table for explanation of the calculation of copper equivalent (Cu Equiv.), MoS₂ equivalent (MoS₂ Equiv.). The presence of the by-product elements gold, silver and rhenium is very significant in terms of the development of the property. Note: Due to recent changes in metal prices, the prices used in the equivalent calculation have been changed to $2.1/lb copper, $10/lb molybdenum oxide and 0.96/gram silver.

The table below lists the location and orientation of the current drill holes. All holes are being surveyed down the hole using a Reflex survey instrument.

In other news, the branding of the new company is well underway with updated corporate materials and innovative marketing campaigns. Significant discussions are proceeding with groups in North America, Europe and Asia interested in funding the CuMo Project to feasibility.

Forward-looking information

This news release contains “forward-looking information” within the meaning of applicable Canadian securities legislation including, but not limited to, statements that address activities, events or developments that CuMoCo expects or anticipates will or may occur in the future, such as the CuMoCo’s ability to move its CuMo project to feasibility and production, and to become one of the largest and lowest-cost molybdenum producers in the world as well as a significant producer of copper and silver. Forward-looking information is based on a number of material factors and assumptions, including the result of exploration activities, the ability of CuMoCo to raise the financing for a feasibility study and to put the CuMo project into production, that no labour shortages or delays are experienced, that plant and equipment function as specified that the Court will not intervene with CuMoCo’s proposed exploration activities at the CuMo project, and the ability of CuMoCo to obtain all requisite permits and licenses to bring the CuMo project into production. Forward-looking information involves known and unknown risks, future events, conditions, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future prediction, projection or forecast expressed or implied by the forward-looking information. Such factors include, among others, the interpretation and actual results of current exploration activities; changes in project parameters as plans continue to be refined; future prices of molybdenum, silver and copper; possible variations in grade or recovery rates; labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing, as well as those factors disclosed in CuMoCo’s publicly filed documents. There may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking information. Except as required under applicable securities legislation, CuMoCo undertakes no obligation to publicly update or revise forward-looking information.
