ALPHA MINERALS JV CONFIRMS SIGNIFICANT MINERALIZATION WITH STRONG "OFF-SCALE" RADIOACTIVITY AT R945E ZONE AT PLS PROJECT
Alpha Minerals Inc. and its 50-per-cent joint venture partner Fission Uranium Corp. have released results from two additional holes drilled (PLS13-092 and 096) on the R945E zone at their Patterson Lake South (PLS) property in Canada's Athabasca basin. PLS13-096 returned 103.5 metres of total composite mineralization (within depths of 94.0 to 317.5 m), including 9.92 m total composite off-scale (greater than 9,999 counts per second (cps)) recorded within several intervals including a discrete 3.19 m of continuous off-scale. These are the widest continuous and strongest results encountered to date at the R945E zone. The joint venture has now hit significant off-scale mineralization at all four zones at PLS (R00E, R390E, R780E and R945E).
Drilling highlights include:
-
PLS13-096: multiple intervals of variable-strength mineralization that
yield a total composite of 103.5 m mineralization within a 223.5 m section
(94.0 to 317.5 m), where barren intervals range from widths of two to
19.0 m; mineralized widths ranging from 0.5 to 42.5 m and are highlighted
by:
- 42.5 m of continuous, variable-strength mineralization (135.5 m to
178.0 m), including:
- 3.21 m of total composite off-scale (greater than 9,999 cps)
radioactivity in several intervals.
- 14.5 m of continuous, variable-strength mineralization (249.0 m to
263.5 m) including:
- 4.39 m of total composite off-scale (greater than 9,999 cps)
radioactivity in several discrete intervals including a discrete
3.19 m of continuous off-scale starting at 253.0 m.
R945E zone
The R945E zone discovery was the result of drill testing a radon-in-water anomaly identified during the partial infill coverage survey of the radon-in-water and radon-in-sediment survey program completed in April, 2013, by RadonEx. The radon anomaly is the strongest radon-in-water anomaly to date at Patterson Lake South (see news release dated May 6, 2013). This anomaly lies along an east-northeast trend, parallel to the southernmost EM conductor, PL-3BM.
Hole PLS13-092 (line 945E) was collared as a vertical hole and completed to a depth of 377.0 m. Moderate to locally strongly anomalous and intermittent radioactivity was encountered between the depths of 157.5 to 318.0 m in intervals ranging from 0.5 m up to 16.0 m wide. The best grade radioactivity is present in a 16.0 m interval from 163.0 to 179.0 m which is moderate to locally strongly radioactive throughout including several narrow intervals from 0.2 to 0.5 m wide of off-scale (greater than 9,999 cps) totalling a composite of 0.9 m. Basement bedrock was encountered at 59.0 m below the surface. The basement lithology comprises alternating sequences of predominantly pelitic and psammitic gneiss. A diabase unit was intersected from 362.8 to 377.0 m to the end-of-hole depth.
Hole PLS13-096 (line 930E) was collared as a vertical hole and completed to a depth of 365.0 m. The hole is located approximately 15 m grid west of hole PLS13-084 (18.0 m of radioactive mineralization with 2.7 m total composite off-scale (see news release Aug. 15, 2013)). A total of 17 discrete intervals of moderate to strongly radioactive mineralization within a 223.5 m section (94.0 m to 317.5 m) in widths ranging from 0.5 m to 42.5 m. Four of these intervals contain discrete intervals of off-scale (greater than 9,999 cps) radioactivity from 0.1 to 3.19 m wide, for a total measured composite of 9.92 m of off-scale radioactivity. Basement bedrock was encountered at 56.5 m below the surface. The upper part of the lithologic sequence (56.5 m to 84.1 m) comprises a quartzitic gneiss. From 84.1 to 276.7 m pelitic gneiss dominates with local narrow intervals (0.9 m to 9.4 m wide) of undifferentiated mylonites, transitioning to a semi-pelitic gneiss from 276.7 m to 365.0 m to the end-of-hole depth. Moderate chlorite alteration is present throughout the hole from 56.5 m to 136.0 m, with hematitic clay dominating from 136.0 m to 175.4 m. Sulphide-bearing intervals occur from 175.4 m to 241.6 m.

A $6.95-million, 44-hole, 11,000 m drill program and ground geophysics surveys continue 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, like the downhole gamma probe 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 downhole core interval measurements and true thickness is yet to be determined.
Radiometric surveys are planned for all holes using a Mount Sopris 2GHF-1000 triple gamma probe, which allows for more accurate measurements in high-grade mineralized zones.
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 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.

Patterson Lake South property
The 31,000-hectare (76,000-acre) PLS project is a 50/50 joint venture held by Alpha Minerals and Fission Uranium. The joint venture property is 100 per cent owned with no underlying royalties or vendor payments. Alpha may return as the operator of the joint venture in 2014. For the present work, the exploration is being operated under the direction of the joint venture management committee and further work is still planned for targets on land to the southwest of the discovery zone R00E.
The property is accessible by road with primary access from all-weather Highway 955, which runs 74 kilometres north to the former Cluff Lake mine (greater than 60 million pounds of U3O8 produced from multiple open-pit and underground mines), and passes through the claims covering the UEX-Areva Shea Creek discoveries located 58 km to the north, currently under active exploration and development.
The technical information in this news release has been prepared in accordance with the Canadian regulatory requirements set out in National Instrument 43-101 and reviewed on behalf of Alpha Minerals by Garrett Ainsworth, PGeo, vice-president, exploration, a qualified person.
We seek Safe Harbor.
