American CuMo Mining Corporation: US Forest Service Supplemental Environmental Assessment Paves Way for Completion of Strategic Metals Exploration in Idaho

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 19, 2013) - American CuMo Mining Corp. (CuMoCo) (TSX VENTURE:MLY)(OTCQX:MLYCF) is pleased to announce that the U.S. Forest Service (USFS) has released its Supplemental Environmental Assessment (EA) regarding the CuMo Exploration Project. The report, issued August 15, 2013, follows the Forest Service's 2011 Decision Notice and Finding of No Significant Impact and will enable fulfillment of a federal judge's order to carry out studies necessary for completion of the exploration phase of the CuMo Project's large strategic metals asset in Idaho.

The new report demonstrates that by following proper procedures, the exploration program can avoid or mitigate groundwater quality impacts - a key consideration for the federal district court.

The Supplemental EA study resulted from an August 2012 decision rendered by Federal District Court Judge, Edward Lodge, in response to litigation filed by environmental groups challenging the U.S. Forest Service's Environmental Assessment process and its Finding of No Significant Impact relative to the CuMo Exploration Project. While Judge Lodge affirmed the Forest Service process and denied four of the five claims in the litigation, the fifth claim regarding deficiencies in groundwater analysis was remanded to the USFS for further clarification.

"While the 2011 EA did include groundwater data related to the CuMo Project exploration, it needed to be presented in a more comprehensive manner in the document prepared by the Forest Service," said Shaun Dykes, Chief Executive Officer of CuMoCo. "In addition, more current information was presented on wildlife and plant resources within the study area so that this assessment will be an up-to-the-minute analysis."

The release of the Supplemental EA begins a 30-day public comment period, beginning August 20 and ending Sept. 18, 2013. The USFS is in charge of that process.

The Forest Service's response to the court focuses on the following subject areas:

• Deeper analysis directed by the court on potential impacts to groundwater quality;
• Additional reporting required by the court addressing mitigation and monitoring measures;
• An update to changes in status of the wolverine and gray wolf under the Endangered Species Act;
• Additional monitoring information performed in 2011 and 2012 on the great gray owl and northern goshawk;
• Rare plant inventories performed on Sacajawea's bitterroot;
• Additional narrative about the CuMo Project's Comprehensive Plan of Operation and Best Management Practices Checklist concerning approved temporary roads and drill pad construction and reconstruction.

In February 2013, the USFS determined to address Judge Lodge's decision in a supplemental addendum to the original EA. The report clarifying groundwater assessment is the culmination of the efforts of the USFS and Enviroscientists (http://enviroincus.com), an independent third-party contractor that performed the work.

"We are pleased with the extraordinarily high level of effort the USFS put into its rigorous environmental review," said Dykes "They left no stone unturned and held us to the highest standards. That fits perfectly with this company's commitment to environmental excellence. The release of the Supplemental EA is positive step in a transparent and ongoing public process."

CuMoCo has been conducting scientific exploration of the CuMo Project since 2004 and relies on scientific methodology and best mining practices in every facet of research and development. Corporate leadership believes the outcome of the USFS EA studies will affirm that the CuMo Project can proceed with full and complete exploration - with little impact to the environment and a substantial positive impact on the economy.

"CuMoCo has once again demonstrated its commitment to a strong working relationship with the USFS and the communities of Idaho," said Dykes. "Our industry-leading environmental practices are dedicated to advancing this vital exploration program."

"With the cooperation of the USFS, best management practices and vital support of the community, the CuMo Project should be advanced," said Dykes. "As CuMoCo works through the environmental assessments, we believe we will be able to reach our goal of bringing thousands of jobs to Idaho and billions of dollars of construction and development spending to Idaho."
