Alpha Minerals Inc. (TSX VENTURE:AMW)(FRANKFURT:E2GA) ("Alpha" or "the Company")
and its 50% Joint Venture partner Fission Uranium Corp. are pleased to announce
partial results of its first hole of the summer drill season, testing the
western extension of the R390E zone. Hole PLS13-072 (drilling still in
progress), has so far returned a broad 85.5m interval (62.0m - 147.5m) of
variably radioactive mineralization including a total of 18.93m of off-scale
(greater than 9999 cps) radioactivity in numerous narrower intervals throughout.
The hole is located 15m grid west of hole PLS13-061, previously the western-most
hole testing the R390E zone. Scintillometer results for hole PLS13-072 overall
are stronger, wider, more continuous and contain significantly more off-scale
radioactivity than PLS13-061 (see news release dated April 3, 2013). Drilling of
hole PLS13-072 is still in progress at a depth of 185.1m, but temporarily
on-hold for mechanical reasons and is awaiting replacement.
PLS13-072 Highlights:
-- 85.5m (62.0m - 147.5m) wide main zone containing total of 18.93m of off-
scale (greater than 9999 cps) radioactivity.
-- Main zone characterized by variable radioactivity from weak-to-very
strong throughout.
-- Off-scale mineralization comprised of multiple narrower intervals of
off-scale (greater than 9999 cps) radioactivity ranging in width
from 0.1m to 4.6m wide each, totaling 18.93m.
-- Expands the western boundary of the R390E zone by 15m.
-- Main wide zone of variably radioactive mineralization starts at shallow
depth of 62.0 m, and two narrower intervals starting at 157.5 m and
169.5 m of weak-to-moderate radioactivity as measured with a GR-110 hand
held scintillometer.
Key Technical Details
-- Hole PLS13-072 (R390E Zone line 345E) was collared as a vertical hole
and is still in progress at a depth of 185.1m. The collar is located 15m
grid west of PLS13-061 (23.5m @ 1.39% U3O8 including 6.0m @ 4.34% U3O8
(see news release June 5, 2013), and represents a significant
intersection at the R390E zone.
-- This new drill hole represents a shallow, very broad interval of almost
continuous radioactivity and, importantly, extends the R390E Zone an
additional 15.0m west.
The relevant geological features of the hole are as follows:
-- Basement bedrock was encountered at 55.7m depth, immediately below the
overburden with no Devonian sandstone encountered above the basement.
-- In drill hole PLS13-072 there is a marked difference in the absence of
Devonian sandstone, and greater depth to the top of basement rocks
compared to drill holes located along strike to the east within the
R390E zone. This may be a result of the RC rig casing past the
overburden and bedrock contact, and so the presence or absence of
Devonian sandstone is inconclusive. Alternatively, the lack of Devonian
sandstone and presence of shallower mineralization may indicate that the
bedrock source of the high grade uranium boulders is possibly
approaching further to the west of PLS13-072. Other step out drill holes
may resolve this.
-- From 55.7m to 163.0m basement lithology consists of alternating
sequences of moderate-to-steeply dipping pelitic gneiss and mylonites.
This alternating sequence is underlain by semi-pelitic gneiss from
163.0m to the present drilling depth.
-- Moderate-to-locally-strong clay alteration is present throughout the
pelitic gneiss/mylonite package.
-- Radioactive mineralization (62.0m - 147.5m) starts 6.3m below the
overburden - basement unconformity and is dominantly constrained within
the pelitic gneiss/mylonite rocks, though weak mineralization continues
below within the semi-pelitic gneiss. The upper 5.0m of mineralization
being very weakly radioactive while more intense mineralization begins
at 67.0m and continues to 108.0m, consisting of weak-to-strong
radioactivity including numerous narrower intervals of off-scale
(greater than 9999 cps) radioactivity each ranging in width from 0.1m to
4.6m wide.
-- From 108.0m to 125.0m, mineralization is weak-to-moderately radioactive
and increasing to moderate-to-locally-strong from 125.0m to 147.5m.

A $6.95M, 44 hole, 11,000m drill program and ground geophysics surveys continues
at PLS.
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. 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 is yet to be determined.
All holes are planned to be radiometrically surveyed using a Mount Sopris
2GHF-1000 Triple Gamma probe, which allows for more 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 U3O8 (wt %) and fire assay for gold. All
samples sent for analysis will include a 63 element ICP-OES, uranium by ICP-MS
and boron. Assay results will be released when received.
