Patterson Lake South gives Fission 91 metres of 4.29% U3O8
High grades and shallow depths continue to characterize Fission Uranium’s (TSXV:FCU) Patterson Lake South. A June 16 batch of assays found positive results from three holes targeting the eastern part of R780E, the middle of five zones along a 2.24-kilometre potential strike. The two best holes showed:
- 0.11% uranium oxide (U3O8) over 13 metres, starting at 137 metres in downhole depth
- 0.2% over 22 metres, starting at 153 metres
- 1.88% over 3.5 metres, starting at 190.5 metres
- 2.48% over 4.5 metres, starting at 209.5 metres
- 7.85% over 3 metres, starting at 221.5 metres
- (including 18.1% over 1 metre)
- 4.29% over 91 metres, starting at 97 metres
- (including 14.69% over 6.5 metres)
- (and including 21.2% over 7 metres)
- 3.5% over 2.5 metres, starting at 228 metres
True widths weren’t provided. Another hole testing the gap between R780E and discovery zone R00E to the west failed to find significant mineralization.
The results followed a late May batch that featured 4.44% U3O8 over 38 metres. The tally from last winter’s campaign now stands at 44 holes reported and 48 pending.
With still no word on a maiden resource, another question remains outstanding: When will someone find the source of the uraniferous boulder field that inspired so much successful drilling since November 2012?
Denison boosts Wheeler River to 70 million pounds indicated, drills Gryphon zone
Denison Mines TSX:DML reported a 34% increase for the indicated category of the Phoenix zone on its Wheeler River joint venture June 17. The resource uses a 0.8% cutoff to estimate:
- indicated: 166,400 tonnes averaging 19.13% for 70.2 million pounds U3O8
- inferred:8,600 tonnes averaging 5.8% for 1.1 million pounds
With a 60% interest in Wheeler River, project operator Denison’s share comes to 42.1 million pounds indicated and 600,000 pounds inferred. Cameco Corp TSX:CCO holds a 30% interest while JCU (Canada) Exploration holds the rest.
The estimate was based on 25 new holes in addition to the 2012 resource. With mineralization at 400 metres in depth and varying from disseminated to massive, “Phoenix belongs to a select group of very high-grade unconformity uranium deposits that includes the prolific McArthur River mine (37 kilometres to the northeast) and the Cigar Lake mine (80 kilometres to the northeast),” Denison stated.
JV partner Cameco operates the Key Lake mill about 35 kilometres northeast of Wheeler.
The Phoenix upgrade notwithstanding, Wheeler’s newly discovered Gryphon zone has taken centre stage. Now underway is a two-drill, 18-hole, 14,000-metre summer program three kilometres northwest of Phoenix. Meanwhile Denison has a 3D DC-resistivity survey planned for the northern extension of the Phoenix trend.
The previous week Denison closed its most recent company acquisition, of International Enexco. With $15 million committed to Canadian exploration in 2014, Denison announced its summer plans earlier this month.
Aldrin’s first three Anticline holes at Triple M reveal radioactivity
Aldrin Resource TSXV:ALN reported more radioactive mineralization from the Anticline target on its PLS-adjacent Triple M property June 19. Results for the first three holes showed significant intervals above 300 counts per second for widths above 0.3 metres as measured by a downhole radiometric probe.
Hole ALN14-008 had been reported in late May but further drilling found additional radioactivity in small intervals ranging from 0.4 metres to 6.5 metres (not true thicknesses) of mineralization between downhole depths of 176.6 and 323.9 metres.
ALN14-009 showed radioactivity in several small intercepts between 214.9 and 289.1 metres in depth, while ALN14-010 revealed intervals between 226.7 and 282 metres.
The company cautioned that radiometric results could indicate potassium or thorium. Aldrin describes the Anticline target as “a coincident basement conductor, gravity low and structural feature extending more than 2.5 kilometres on strike.” These three holes tested its northeast corner.
Drilling will resume “immediately following our high-resolution surface geophysics and geochemistry,” CEO Johnathan More stated.
In April the company released initial results from four of seven holes on Triple M’s Forrest Lake fault. The 12,000-hectare project comprises two blocks west and south of PLS.
Fission 3.0, Azincourt to begin summer drilling at Patterson Lake North
Adjacent and to the north of PLS, Patterson Lake North has four or five holes totalling about 1,600 metres that were expected to begin imminently, according to June 16 announcements from Fission 3.0 TSXV:FUU and Azincourt Uranium TSXV:AAZ. The plan is to test the project’s A1 and A4 conductors with three holes spaced 400 metres apart and a fourth contingent on the first three results. Winter drilling failed to find radioactivity but did “confirm the high prospectivity of the target areas,” the companies stated last April.
The Fission 3.0 portfolio also includes a Peruvian interest in addition to nine others in Saskatchewan and Alberta. Late last month the company joined Brades Resource TSXV:BRA to announce VTEM results from their Clearwater West joint venture.
