Fission, Alpha Drill 21.65 Metres of Radioactivity at PLS
Alpha Minerals Inc. (TSX-V: AMW), (the “Company” or “Alpha”), and its 50% Joint Venture partner Fission Uranium Corp. (TSX-V: FCU) are pleased to announce results for an additional two holes drilled on the R390E Zone. Holes PLS13-073 and PLS13-075 tested the eastern and western extension of the zone respectively and both intersected mineralization. The strike length of the R390E zone has now been increased to 105m at an early stage of the summer drill program. At 21.65m off-scale (>9999 cps) mineralization, PLS13-075 represents the largest accumulation of discrete off-scale mineralized intervals in any drill hole at PLS to date. Drilling of hole PLS13-075 is still in progress at a depth of 188.0m, and it is expected that the main zone of mineralization has been intersected and reported in this news release.
PLS13-075 Drilling Highlights include:
-
Extends strike length of R390E zone to 105m
-
21.65m total off-scale radioactivity in several discrete intervals including
o16.7m of continuous off-scale (>9999 cps) (73.5m – 90.2m)
-
82.0m of variable strength basement mineralization in two zones, separated by only 2.5m of barren rock
-
The upper zone (57.5m – 127.5m), which includes the 21.65m of total composite off-scale, reported variable weak to strong radioactivity
-
The lower zone (130.0m – 142.0m) reported weak to moderate radioactivity
-
Multiple narrow anomalous radioactive intervals present from 146.5m to 162.5m
R390E Zone:
Line 330E: Drill hole PLS13-075 (drilling is still in progress) was collared as a vertical hole. The hole is still in progress at a depth of 188.0m. The hole is collared 15m grid west of PLS13-072. Two main zones of mineralization were intersected (70.0m and 12.0m wide respectively), separated by 2.5m of unmineralized rock. The upper zone (57.5m – 127.5m) is characterized by variably weak to strong radioactivity throughout. A total cumulative of 21.65m of off-scale radioactivity (>9999 cps) was intersected throughout, with the largest discrete interval measuring 16.7m (73.5m – 90.2m). The lower zone (130.0m – 142.0m) is characterized as weak to moderate radioactivity throughout. Several additional narrow intervals of generally weak mineralization were present from 146.5m to 162.5m (see Table 1), including a 2.5m wide interval (146.5m – 149.0m of weak to strong mineralization including a narrow 0.15m wide interval of off-scale (>9999 cps) radioactivity at 147.13m. A thin cap of Devonian sandstone was encountered from 47.0m to 49.3m, overlying a quartzitic gneiss to a depth of 55.6m. The quartzitic gneiss was underlain by a foliated and locally faulted strongly altered locally strongly graphitic pelitic gneiss. Foliation is generally moderate to steep to core axis at 020° to 048°. The hole is still in progress at a depth of 188.0m. Moderate to strong clay alteration is present from 49.3m to 162.5m.
Line 435E: Drillhole PLS13-073 was collared as a vertical hole. The hole was drilled to a depth of 248.0m. The hole is collared 15m grid east of PLS13-066. Two zones of mineralization were intersected (19.5m and 11.0m wide respectively), separated by 21.0m of unmineralized rock. The upper zone (102.0m – 121.5m) is characterized by variably weak to moderate radioactivity throughout. A narrow 0.1m wide interval of off-scale radioactivity (>9999 cps) was intersected at 107.79m. The lower zone (142.5m – 153.5m) is characterized as weak to locally strong radioactivity throughout. A narrow 0.33m wide interval of off-scale radioactivity (>9999 cps) was intersected at 138.1m. A thin cap of Devonian sandstone was encountered from 50.0m to 53.0m, overlying a quartz-feldspar granofel to a depth of 90.1m. The quartz-feldspar granofel was underlain by alternating sequence of pelitic gneiss and mylonites to the end of hole depth of 248.0m. The foliated pelitic gneiss and mylonite sequence is moderately clay altered to 226.0m and sulphide bearing from 235.5m to 248.0m. Foliation is generally steep to core axis at 010° to 040°. The hole was terminated at a depth of 248.0m in unaltered sulphide bearing pelitic gneiss. It appears that this drill hole tested south of the upper pelitic gneiss and quartz-feldspar granofel contact, which has been the optimal area for intersecting high grade mineralization in the R390E zone. Stepping out to the north of drill hole PLS13-073 should test this highly prospective zone.

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.
