Strathmore Reports Favourable Preliminary Economic Assessment &
Updated Resource Estimate for Roca Honda Uranium Project
KELOWNA, BRITISH COLUMBIA -- (Marketwire) -- 10/24/12 -- STRATHMORE
MINERALS CORP. (TSX:STM)(OTCQX:STHJF) ("Strathmore" or the "Company")
is pleased to report favourable results from a National Instrument
43-101 technical report entitled "Technical Report on the Roca Honda
Project, McKinley County, New Mexico", dated August 6, 2012, and
prepared by Roscoe Postle Associates Inc. ("RPA"). The technical
report includes an updated NI 43-101 compliant mineral resource
estimate and the results of a Preliminary Economic Assessment ("PEA")
for the uranium resources outlined to date at the Roca Honda Project
in New Mexico. The Roca Honda Property is 60% owned by Strathmore and
40% owned by Sumitomo Corporation of Japan under their jointly held
subsidiary, Roca Honda Resources LLC (RHR).
-- Base case estimated pre-tax Net Present Value (NPV) (8% discount), of US
$220 million and pre-tax internal rate (IRR) of return of 19.2%, using
US $75/lb uranium based on independent third party 2015 price forecasts.
Using a uranium price of US $65/lb, the estimated pre-tax NPV (8%
discount) is US $112 million and the IRR is 14%. The current long-term
uranium contract price is US $60/lb.
-- A mine life of nine years by conventional underground methods with a
variable processing rate of 1,030 stoping tons per day during the time
that mining occurs in Property Sections 9 and 16. Production increases
to 1,200 stoping tons per day when Property Sections 9, 16, and 10 are
all mined simultaneously, and then production drops to 1,020 stoping
tons per day when mining from Property Section 10, only.
-- Average annual production over the life of the mine is 2.6 million lbs
of uranium; Estimated initial pre-production cost of approximately US
$344 million, including contingency of $US 61 million. Total capital
costs over the life of the mine are estimated to be US $444.5 million
with contingency. Operating costs are estimated at US$24/lb. Total
Capital, operating and royalty costs per pound are approximately US
$44/lb with contingency and US $41 without contingency. Payback is
approximately four years after production begins. A Sensitivity Analysis
notes the project is most, and equally sensitive to, head grade, the
uranium price and recovery. It is least, and equally sensitive to
operating and capital costs.
A summary of pre-tax financial evaluation using the base case uranium
price of US $75/lb is presented below. The current spot and long-term
uranium prices are considerably below the base case US $75/lb price
used in the PEA, which is derived from independent third-party
forecasts for 2015. The Roca Honda Project includes construction of a
milling facility at RHR's Pena Ranch property with excess processing
capacity which could be used as a regional toll mill. However, the
base case assumes no toll milling, and uses a market price of US
$75/lb for all years.

Strathmore cautions that the PEA is preliminary in nature and
includes inferred resources that are considered to be too speculative
geologically for economic consideration that would enable them to be
classified as mineral reserves. Mineral resources are not mineral
reserves and do not have demonstrated economic viability. There is no
certainty that the PEA will be realized.
The economic evaluation of the Roca Honda uranium resource was
prepared under the supervision of Stuart E. Collins of Roscoe Postle
(USA) Ltd., Lakewood, Colorado. Mr. Collins is a Registered
Professional Mining Engineer in the state of Colorado, and is a
registered member of the Society for Mining and Metallurgy, and
Exploration, and an independent and Qualified Person as defined in NI
Summary of Roca Honda Mineral Resources:
The Roca Honda property represents Strathmore's largest and highest
grade uranium resource. In addition, the updated Roca Honda resource
estimate prepared by RPA confirms Roca Honda as one of the highest
grade uranium deposits in the United States.

The modeling and estimation of the uranium resources were prepared
under the supervision of Patti Nakai-Lajoie, P.Geo. and Principal
Geologist, RPA. Ms. Nakai-Lajoie is a Professional Geoscientist in
the Province of Ontario and an independent and Qualified Person as
defined in NI 43-101. Ms. Nakai-Lajoie visited the Roca Honda
Property on May 10-12, 2011 and is of the opinion that the data
verification procedures support the geologic interpretations and
confirm the quality of the database. It should be noted that mineral
resources, which are not mineral reserves, do not have demonstrated
RPA reviewed historic plans and sections, geological reports,
historic and recent drill hole logs, digital drill hole database,
historic drill hole summary radiometric logs and survey record,
property boundary surveys, and previous Roca Honda resource
estimates. As part of the data verification process, RPA
independently measured counts per second (cps) of select drill core
samples using a hand held scintillometer, and checked some drill hole
collars and section boundaries on the property using a hand held GPS.
The drill hole locations and the presence of uranium were confirmed,
and few discrepancies were identified, during the verification
process or the independent field data verification. Any discrepancies
were either deleted or corrected.
RPA used Maptek's Vulcan(R) 3D modeling software to estimate the Roca
Honda resource. Stationary domains were generated in ARANZ Geo
Limited's Leapfrog(R) version 22.214.171.124 using geologic and drill hole
data to create hard boundaries, which helped control the estimation
process. Uranium (U3O8%) grades were estimated using the inverse
distance weighting method for 10 ft by 10 ft by 6 ft blocks created
inside domains. Validation was done both visually and by comparison
with nearest neighbor estimation method. No significant discrepancies
were identified with block grade validation. Distances to samples and
number of samples used in estimation were used along with geologic
and grade continuity to determine measured, indicated, and inferred
RPA has recommended the project proceed to the pre-feasibility stage
with continuation of the New Mexico State and Federal permitting
process. Overall, a two-phase work program and budget for both the
Roca Honda property and the proposed Pena Ranch mill has been
outlined. Phase 1, budgeted at US $1.9 million recommended the
continuation of additional metallurgical test work, baseline studies,
and monitor well drilling. Phase 2, which is contingent on
successfully completing Phase 1, is budgeted at US $3.1 million.
Phase 2 recommends additional drilling to increase the quantity and
quality of the Mineral Resources, in addition to advanced mill design
and permitting work.
Roca Honda Resources LLC submitted a mine permit application for the
Roca Honda Project in 2009. A draft Environment Impact Statement
(EIS) prepared under the direction of the United States Forest
Service is scheduled to be completed in December 2012, with a final
EIS due in early 2013. The mine permit decision is expected in 2013.
A Nuclear Regulatory Commission license application for construction
and operation of a conventional uranium mill is currently in draft
form, and it is expected to be submitted in early 2013.
