La Jara Mesa

La Jara Mesa, a sandstone-hosted roll front style deposit is located in Grants Mineral Belt, New Mexico, the largest historical uranium district in the United States. The project is at the development stage and will be an underground operation.


LOCATION

Cibola County, New Mexico in the Ambrosia Lake Mining District of the Grants Mineral Belt


KEY ATTRIBUTES:

  • Discovered in 1983 – the last significant discovery to be made in the district
  • Acquired in 2005 from Homestake Mining, which completed extensive work, including metallurgical test work, mine planning and mine permit approval
  • Project has excellent grades and additional exploration potential
  • The current NI 43-101/JORC compliant resource calculation on La Jara Mesa was completed in 2006, and was subsequently amended in July 2007 by Douglas Peters. The Indicated Mineral Resources are estimated at totalling 7.2 million pounds of uranium (U3O8) contained in 1.4 million tonnes at an average grade of 0.23% U3O8, and an additional 3.1 million pounds of uranium (U3O8) contained in 0.7 million tonnes at an average grade of 0.20% U3O8 classified as Inferred Mineral Resources
  • Received draft Environmental Impact Statement from U.S. Forest Services (USFS)

PROGRESS S S AT LA JARA MESA:

On May 18, 2012, the USFS issued a draft EIS for the Company’s La Jara Mesa uranium project. The issuance of the draft EIS represents a milestone in the mine permit process, which would allow underground development activities and mine production at the La Jara Mesa project.  The US Forest Service is currently reviewing the draft EIS in light of public comments and is continuing the Native American Consultation Process. Accordingly, progress will continue with the National Environmental Policy Act (NEPA) review process of La Jara Mesa, which will ultimately lead to the completion of the final EIS. Both this and the Records of Decision (ROD) from the USFS and NEPA are expected in 2013. Upon completion of any conditions in the ROD, the Company will be eligible to receive permits to allow underground development activities and mine production.

 


FUTURE OUTLOOK

Plan of Operations – completed and reviewed by USFS

Environmental Impact Statement – Final phase and public comment period

Permitting – Final permitting approval under way and waiting on Record of Decision

 


GEOLOGY

The La Jara Mesa uranium deposit is a roll front uranium deposit occurring within a sequence of classic Jurassic and Cretaceous sedimentary rocks. Tertiary basaltic lavas occur unconformably on top of the cretaceous sediments.

Uranium mineralization at La Jara occurs within 4 levels of the Poison Canyon sandstone member of the Morrison formation, however the only significant deposits are known within the lower two units. Within the district the Marquez Mine produced 656,000 tonnes grading 0.26 % U3O8. This deposit occurs 4 miles north of La Jara.


HISTORY

Uranium was discovered in the Grants district of New Mexico in the early 1950s. Since the discovery considerable historic uranium exploration activity has been completed on La Jara Mesa by companies such as United Nuclear Corporation, Gulf Resources and Homestake primarily in the 70’s and 80’s. These companies performed exploration work, comprising of over 700 drill holes as well as metallurgical test work. Historical metallurgical studies on La Jara Mesa exhibited strong recoveries and potential underground access is quite straightforward via an inclined ramp from the valley floor. These tests determined that the mineralization would readily leach with acid and recoveries averaging 90% were achieved.
