Alpha Minerals JV R00E Zone, Grows with More "Off-Scale" Radioactivity with Grid Drilling at Patterson Lake South, Athabasca Basin

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 19, 2013) - Alpha Minerals Inc. ("Alpha" or "the Company") (TSX VENTURE:AMW), and its Joint Venture partner Fission Energy Corp. are pleased to announce results from 10 additional step-out drill targets in the R00E zone at the Patterson Lake South (PLS) property. All 10 holes intersected anomalous radioactivity, with 8 holes intersecting significant mineralization, including 6 holes intersecting variable amounts of off-scale radioactivity.

The Operator reports that the R00E zone has now been traced for over 80m of mineralized strike length at shallow depth from PLS13-049 (L060W) to the west to PLS13-052 (L015E) to the east, and over 50m wide (L025W). The zone remains open along strike and width.

Drilling Highlights include:

  • PLS13-052 (L015E) intersected 31.5m of weak to strong mineralization with 5.95m of off-scale (>9999 cps) radioactivity: mineralization starting at 62m
  • PLS13-043 (L040W) intersected 26.5m of weak to strong mineralization with 4.63m of off-scale (>9999 cps) radioactivity: mineralization starting at 63m
  • PLS13-041 (L040W) intersected 19.0m of weak to strong mineralization with 4.15m of off-scale (>9999 cps) radioactivity: mineralization starting at 63m

R00E Zone

Close spaced delineation drilling was completed on lines L040W, L060W and L015E of the R00E zone. Interpretation thus far shows mineralization to be primarily focused across a steeply south dipping package of E-NE trending pelitic gneiss, sandwiched between a semi-pelitic rock to the north and a quartz-feldspar gneiss to the south. Delineation drilling has also shown mineralization to cross lithological boundaries into the footwall and hanging wall adjacent the pelitic gneiss. This conductive lithologic package appears to be parallel along strike to the ~073° oriented basement EM conductor identified from airborne and ground geophysics surveys.

As was the case with previous drill results from the R00E zone, the main mineralized horizon appears to be structurally controlled and generally flat lying within the pelitic (+/- graphite) unit, with the upper level of the mineralized zone occurring at or near the top of the Archean basement rocks, either within or immediately below a thin veneer or Devonian sandstone (see cross-sections L060W, L040W and L015E). Mineralization has been traced northward extending into the semi-pelitic package on sections L025W, 040W and 060W) and remains untested on the other sections.

Description of Drill Results by Section Line

L040W - Four drill holes (PLS13-039, 041, 043 and 045) successfully delineated the width of mineralization over 30m. The drill holes were all collared vertical on a 10m spacing. The best results were returned from hole PLS13-043, drilled 10m south of hole PLS13-041 which intersected 26.5m of weak to strong radioactive mineralization (63.0m to 89.5m), including 4.63m of off-scale (>9999 cps) in several discrete intervals throughout. PLS13-041 intersected weak to moderate mineralization in a 5.5m interval (63.0m - 68.5m) and weak to strong mineralization in a 19.0m interval (72.0m - 91.0m), including 4.15m of off-scale (>9999 cps) radioactivity in several discrete intervals throughout. Hole PLS13-045 collared 10m to the north of PLS13-041, intersected a 25.0m interval of weak to locally strong mineralization (64.0m - 89.0m), including a narrow 0.13m wide interval of off-scale (>9999 cps) radioactivity. Hole PLS13-039 drilled 10m to the south of hole 043 intersected two narrow zones of weak mineralization (125.0m - 128.5m and 161.5m - 163.5m respectively). Two intervals that show as mineralized zones from the down-hole gamma probe survey (65.9m to 66.7m and 72.3m to 75.3m) were washed away as the inspected drill core from these intervals did not reveal correlating radioactivity and mineralization.

L060W - Three drill holes (PLS13-047, 049 and 050) successfully delineated the width of mineralization over 20m. The drill holes were all collared vertical on a 10m spacing. The best results were returned from hole PLS13-049, which intersected a 19.0m interval of weak to strong (64.5m - 83.5m) including 3.35m of off-scale (>9999 cps) radioactivity in several discrete intervals throughout. Hole PLS13-047 was collared 10m to the south of hole PLS13-049 and intersected two intervals of weak radioactivity (64.0m - 68.5m and 105.0m - 107.0m respectively). Hole PLS13-050 was collared 10m north of PLS13-049 and intersected a narrow 1.0m wide interval (63.5m - 64.5m) of weak mineralization.

L015E - Three drill holes (PLS13-052, 054 and 056) successfully delineated the width of mineralization over 20m. All 3 holes were collared at angles of -71° to -72° at azimuths to the N-NE (see Table 1 for collar details). PLS13-052 intersected weak to strong mineralization over a 31.5m interval (62.0m - 93.5m) including 5.95m of off-scale (>9999 cps) in several discrete intervals throughout. Hole PLS13-054, collared 10m grid south of PLS13-052 intersected weak to locally strong mineralization over an 11.5m interval (68.0m - 79.5m), including a narrow interval (0.27m) of off-scale (>9999 cps) radioactivity. Hole PLS13-056 drilled 10m to the north of PLS13-052 intersected a 9.5m wide interval of weak to moderate mineralization (62.5m - 72.0m).

* 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. 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 thickness are yet to be determined.

An ongoing field program is in progress. More than half of the planned program of approximately 8000m of core drilling has been completed. Assay results are beginning to come in from SRC Geoanalytical laboratories and will be reported as they are reviewed and compiled.

All holes are surveyed using a Mount Sopris 2GHF-1000 Triple Gamma probe, which allows for accurate measurements in high grade mineralized zones. The Triple Gamma probe is preferred in zones of high grade mineralization.

Split core samples from the mineralized section of core will be taken continuously through the mineralized intervals and submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis, which includes uranium calculated to U3O8 (wt %) and fire assay for gold. All samples sent for analysis will include a 63 element ICP-OES, uranium by fluorimetry and boron. Assay results will be released when received.
