VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/19/13 -- 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 (greater than 9999 cps) radioactivity: mineralization starting at 62m-- PLS13-043 (L040W) intersected 26.5m of weak to strong mineralization with 4.63m of off-scale (greater than 9999 cps) radioactivity: mineralization starting at 63m-- PLS13-041 (L040W) intersected 19.0m of weak to strong mineralization with 4.15m of off-scale (greater than 9999 cps) radioactivity: mineralization starting at 63m
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 approx. 073 degrees 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 (greater than 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 (greater than 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 (greater than 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.
