Fission, Alpha Minerals drill 10.5 metres of 29% U3O8 at PLS

April 22, 2013

Alpha Minerals Reports 53 metres of 6.57% U3O8 with 10.5 metres of 29.26% U3O8 at Patterson Lake South JV, SW Athabasca Basin

Alpha Minerals Inc. (TSX.V: AMW), and its Joint Venture partner Fission Energy Corp. (TSX.V: FIS) are pleased to report assay results from drill hole PLS13-051, part of its successful winter drill program and radon survey on its Patterson Lake South ("PLS") property.

Monday 22nd, 2013, Alpha Minerals Inc. ("Alpha" or “the Company") (TSX.V: AMW), and its Joint Venture partner Fission Energy Corp. are pleased to report assay results from drill hole PLS13-051, part of its successful winter drill program and radon survey on its Patterson Lake South ("PLS") property.

PLS 13-051 Drilling Highlights:

◾53.0m @ 6.57% U3O8;

◾Including 10.5m @ 29.26% U3O8

◾Highest assay in the interval: 44.6% U3O8 over 0.5m

PLS13-051, within zone R390E, is located 15m grid east of PLS13-038 (see news release dated March 24, 2013) in which assays included 4.92% over 34m and today’s assays represent the best results to date. Like drill hole PLS 13 – 038, this latest drill hole was targeted within the large radon anomaly in lake water sampling identified in earlier work this year by the Joint Venture. The radon anomaly extends beyond the area drilled to date.

The drill hole was vertical and intersected the mineralization within a steeply dipping interval of graphitic meta pelitic rock. All measurements of length reflect drill core lengths here and have not been estimated as true widths. There is significant matching of similar assays or scintillometer evaluations of the drill holes in this zone over a strike length now exceeding 30 meters and all well within the radon anomaly.

An extension of the radon survey is currently being carried out to extend the original experimental radon work. The results of which, to date, include the discovery of zones R390E and R790E indicating that significant uranium mineralization is a source, more than 50 meter deep, of the radon anomalies in those zones.

Composited U3O8 mineralized intervals are summarized in Table 1 below. The results show that the uranium is concentrated continuously throughout the 53m interval (95.0m – 148.0m), and with a 19m wide higher grade core (101.5m – 120.5m) that averages 17.28% U3O8. Within the higher grade core is a 10.5m wide interval (107.5m – 118.0m) which grades 29.26% U3O8. Not all assay results have been received for PLS13-051, but the outstanding intervals are not expected to contain anomalous uranium values.

Hole PLS13-051 was collared as a vertical hole and was completed at a depth of 282.5m. The collar is located 405m grid east of discovery hole PLS12-022 (8.5m @ 1.07% U3O8; see news release December 5, 2012). The relevant geological features of the hole are as follows: At 48.2m depth, a thin (3.4m wide) cap of probable Devonian Sandstone was encountered which overlies alternating sequences of quartzitic and pelitic gneiss to 120m. Graphitic shear zones, +/- sulphides, dominate from 120.0m to 213.1m. From 213.1m – 282.5 (EOH) basement rocks consist of pelitic and semipelitic gneiss.   The main mineralized horizon was encountered from 95.0m – 148.0m and is associated with the transition from a quartz-feldspar gneiss above to a pelitic gneiss below. Uranium mineralization occurs as flecks, blebs, clots, veins, semi-massive and wormhole style.

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). The Joint Venture property is 100% owned with no underlying royalties or vendor payments. Fission is the Operator until April 1st 2014. The property is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine, (>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.

Alpha “Area” Properties

Alpha Minerals also is carrying out exploration on a uranium project next to the Cluff Lake Mine licence. The Company holds a large claim block over its Hook Lake property that covers the northern extensions of the fertile Patterson Lake and Derkson Conductor trends and is flanked by the Purepoint-Cameco- Areva JV and the Nexgen- Clermont   project area. Further work is planned for this year on all properties.

Staking activity in the area surrounding the JV accelerated this year with more than twice the area occupied by the JV now covered with new tie on claims. Updated maps highlighting the drilling programs for PLS can be found on the Company's website at
