Alpha Minerals Hits 18.9m Total of "Off-Scale" in Hole PLS13-053 at Patterson Lake South
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/13/13 -- Alpha Minerals Inc. ("Alpha" or "the Company") (TSX VENTURE: AMW), and its Joint Venture partner Fission Energy Corp. are pleased to announce the most recent drill results from delineation drilling in the recently discovered R390E zone. (See news release dated March 11, 2013). With 18.9m of off-scale (greater than 9999 cps) mineralization, PLS13-053 represents the widest, largest accumulation of discrete off-scale mineralized intervals in any drill hole on Patterson Lake South ("PLS") property to date.
PLS13-053 Drilling Highlights include:
-- 15m step out west of PLS13-038 extends strike length of R390E zone to
30m
-- 67.0m of basement mineralization in two zones, separated by only 3.5m of
barren rock
-- Upper zone (66.0m - 116.5m) with 17.4m total off-scale radioactivity in
several discrete intervals including 8.9m of continuous off-scale
(greater than 9999 cps) (95.5m - 104.4m)
-- Lower zone (120.0m - 136.5m) with 1.5m of off-scale in two discrete
(greater than 9999 cps) intervals
-- PLS13-053 Up-Hole Triple Gamma Log is attached at the end of the news
release.
R390E Zone:
Drill hole PLS013-053 was collared as a vertical hole, but deviated slightly to a dip of -89.26 degrees to the SE. The hole was drilled to a depth of 282.5m. The hole is collared 15m grid west of PLS13-038. Two main zones of mineralization were intersected (50.5m and 16.5m width respectively), separated by 3.5m of unmineralized rock. The upper zone (66.0m - 116.5m) is characterized by weak to moderate to strongly mineralized throughout. A total of 17.4m of off-scale radioactivity (greater than 9999 cps) was intersected throughout, with the largest discrete interval measuring 8.9m (95.5m to 104.4m). The lower zone (120.0m to 136.5m), similar to the upper zone, is characterized by weak to moderate to strong mineralization throughout. A total of 1.5m of off-scale radioactivity (greater than 9999 cps) was intersected in 2 discrete intervals. Several additional narrow intervals of weak mineralization were present from 145.0m to 219.5m (see Table 1). A thin cap of Devonian sandstone was encountered from 49.4m to 51.4m, overlying a quartzitic gneiss to a depth of 57.5m. The quartzitic gneiss was underlain by an intensely altered graphitic pelitic gneiss hosting multiple discrete graphitic shear zones. The hole was terminated at a depth of 282.6m in barren unaltered semi-pelitic gneiss. Moderate to strong clay alteration is present from 51.4m to 159.3m, flanked above and below by weak to moderate clay and chlorite alteration.
All intersections reported herein are not true widths but drill core intersections and true widths have yet to be determined. The continuity and similarity of radioactive signatures in these intersections do indicate strong correlation from hole to hole and vertical extents have not yet been limited by drilling.

(i) Scintillometer Instrument: GR-110G
Natural gamma radiation in drill core that is reported in this news release was measured in counts per second (cps) using a hand held Exploranium GR-110G total count gamma-ray scintillometer. Borehole radioactivity is measured downhole using a Mount Sopris 2GHF-1000 Triple Gamma probe. (please refer to the Triple Gamma Log at the end of the news release) The reader is cautioned that scintillometer readings are not directly or uniformly related to uranium grades of the rock sample measured, and should be used only as a preliminary indication of the presence of radioactive materials. The degree of radioactivity within the mineralized intervals is highly variable and associated with visible pitchblende mineralization. All intersections are down-hole, core interval measurements and true thicknesses are yet to be determined.
Approximately 8,000m of core drilling is planned to continue delineation and definition the several mineralized regions identified during the 2011 and 2012 exploration programs.
All holes are to be surveyed using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for accurate measurements of radioactivityin high grade mineralized zones. The Triple Gamma probe is preferred in zones of high grade mineralization. The Operator, Fission Energy Corp, has used this system extensively in the J Zone drilling, the eastern extension of the Roughrider deposits discovered Hathor Exploration.
Patterson Lake South Property
The 31,000 hectare (76,000 acres) PLS project is a 50%/50% Joint Venture held by Alpha Minerals Inc (AMW) and Fission Energy (FIS). Fission is the Operator until April 1st 2014. PLS is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine, (greater than 60M lbs of U3O8 produced), and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development. Updated maps highlighting the core and reverse circulation drilling programs planned for PLS can be found on the Company's website at http://www.alphaminerals.ca.
