Strathmore Completes Agreement With Nu-Mex Uranium for US$44.5 Million Commitment at Nose Rock, New Mexico Uranium Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 20, 2007) - Strathmore Minerals Corp. (TSX VENTURE:STM) is pleased to announce that its subsidiary, Strathmore Resources (US) Ltd. ("Strathmore" or "the Company"), has completed a formal option and joint venture agreement with Nu-Mex Uranium Resources Inc. ("Nu-Mex") to explore and develop Strathmore's Nose Rock properties (the "Nose Rock Project") - see news release dated June 18, 2007.

The Nose Rock Project is located northeast of Crownpoint within the Grants Mineral Belt in the State of New Mexico. The Company acquired the property through mineral leases or by claim staking and the Nose Rock Project as a whole consists of approximately 5,000 acres (2,023 Ha) of land. According to the previous operator Phillips Uranium, a division of Phillips 66 Oil Company in the 1970's, part of the original mine site now under Strathmore's control, contains a demonstrated resource of 6,694,217 tons ore grading 0.135% U3O8. This historical resource totals 18,230,955 lbs U3O8 (not 43-101 compliant). The discovery of the Nose Rock ore body by Phillips Uranium was announced in December, 1975 (p. 20, New Mexico Bureau of Mines and Minerals, Memoir 38, 1979).

The completed agreement provides that Strathmore will grant Nu-Mex sole and exclusive right to earn-in up to a 65% interest in the Nose Rock Project on the following terms (all dollar amounts are in US$):

1. Nu-Mex will pay to Strathmore $250,000 on closing and issue to the limited liability company to be formed to consummate this joint venture between the parties 5,000,000 common shares in the capital stock of Nu-Mex; and

2. Nu-Mex will incur a total of $44,500,000 in work commitment expenditures on the Nose Rock Project in accordance with the following schedule:

- $1,000,000 in work commitment expenditures in each of the first and second years,

- an additional $1,500,000 in work commitment expenditures in the third year,

- an additional $10,000,000 in work commitment expenditures in each of the fourth, fifth and sixth years, and

- an additional $11,000,000 in work commitment expenditures in the seventh year.

Nu-Mex will earn a 25% interest in the Nose Rock Project once Nu-Mex has completed the work commitments (US $13,500,000) required on or before the anniversary of the fourth year. Nu-Mex will earn an additional 40% interest in the Nose Rock Project once Nu-Mex has completed the additional work commitments (US $31,000,000) required on or before the anniversary of the seventh year. Strathmore has the right to pay US $25,000,000 to earn back a 16% interest in the Nose Rock Property if it so chooses.

The agreement contemplates that after the fourth year, and provided Nu-Mex has fulfilled its commitments, the parties shall review all work completed and prepare an independent NI 43-101 compliant technical report and resource calculation. Recommendations from this report will help plan further development initiatives.

The foregoing historical resource estimates were completed prior to the implementation of NI 43-101. Given the quality of the historic work completed on the properties discussed herein, the Company believes the resource estimates to be both relevant and reliable. However, a qualified person has not completed sufficient work to classify the historic mineral resources as current mineral resources, and is not treating the historic resources as current. Hence, they should not be relied upon. The technical information in this news release has been prepared in accordance with the Canadian regulatory requirements set out in National Instrument 43-101 and reviewed by David Miller, President and Chief Operating Officer for Strathmore Minerals Corp., a qualified person under National Instrument 43-101.
