Regional drilling disappoints at Patterson Lake South as Fission/Alpha finish otherwise successful campaign
by Greg Klein | November 28, 2013
Two of Patterson Lake South’s final 11 autumn holes confirmed continuity along a 30-metre strike at the project’s recently discovered sixth zone. But nine others failed to find significant radioactivity, according to scintillometer results released by Fission Uranium TSXV:FCU and Alpha Minerals TSXV:AMW on November 27. The non-mineralized nonet, sunk further west of the project’s western-most R600W zone, might please only an anti-nuke activist. Nevertheless “varying degrees of secondary hydrothermal alteration were present in all holes, thus providing encouragement for the prospectivity of the western strike extension” of the PL-3B EM conductor corridor. R600W remains open in all directions, the 50/50 joint venture partners maintain.
Their hand-held scintillometer measures gamma ray particles in drill core up to a maximum reading of 9,999 counts per second. These results are no substitute for assays, which are still to come. But don’t hold your breath—so are assays for 40 holes drilled last summer.
Of the two mineralized holes, PLS13-123 reached a total depth of 260 metres, encountering sandstone at 90.7 metres and the basement unconformity at 100 metres. Some highlights show:
- <300 to 1,200 cps over 20 metres, starting at 95 metres in downhole depth
- <300 to 5,100 cps over 7.5 metres, starting at 132.5 metres
- 320 to 2,300 cps over 2.5 metres, starting at 142.5 metres
Hole PLS13-124 found sandstone at 97.5 metres and the basement unconformity at 99 metres before stopping at 257 metres. Highlights include:
- 450 to 5,500 cps over 6.5 metres, starting at 97.5 metres
- <300 to 1,300 cps over 7.5 metres, starting at 114 metres
- <300 to 2,500 cps over 11.5 metres, starting at 197 metres
True widths weren’t available. With dips of -87 and -89 degrees respectively, the two holes’ downhole depths are close to vertical.
The 11 land-based holes bring an end to this drill program, most of which took place from barges over the lake. Fifty-three holes totalling 16,485 metres found six near-surface zones along a 1.76-kilometre trend. Ending the season on a triumphant note, Alpha president Ben Ainsworth said the 12-month campaign nearly equalled “what was completed in four years of work on Hathor’s Roughrider discovery.”
