Fission/Alpha report 4 PLS holes, R00E zone still open
So far this summer, three previous step-outs have extended the middle of Patterson Lake South’s trio of zones. On August 8 Alpha Minerals TSXV:AMW and Fission Uranium TSXV:FCU released scintillometer results from four new holes in the southern-most zone, which remains open along strike and width. Along with the results came some interesting speculation about the mineralization.
The hand-held gamma-ray scintillometer readings, which are no substitute for assays, measure radiation from drill core in counts per second. Anything over 9,999 cps is off scale.
A 15-metre step-out testing the western extent of the zone, hole PLS13-074 was drilled to 203 metres in approximate vertical depth, encountering sandstone at 60.9 metres and a basement unconformity at 66 metres:
- 550 to 1,050 cps over 1 metre, starting at 65 metres in approximate vertical depth
- 370 cps over 1 metre, starting at 105 metres.
The other three holes tested the zone’s centre. Hole PLS13-076 was drilled to 267 metres in approximate vertical depth, encountering sandstone at 54 metres and the basement unconformity at 61.4 metres:
- <300 to 2,700 cps over 14 metres, starting at 177.5 metres in approximate vertical depth.
Hole PLS13-077 was drilled to 259.5 metres in downhole depth, encountering sandstone at 56 metres and the basement unconformity at 61.4 metres:
- 340 to 7,500 cps over 11.5 metres, starting at 59 metres in downhole depth
- <300 to 4,000 cps over 15 metres, starting at 73.5 metres.
Hole PLS13-079 was drilled to 218 metres in downhole depth, encountering no sandstone but hitting the unconformity at 59 metres:
- 340 to >9,999 cps over 18.5 metres, starting at 82.5 metres in downhole depth
- (including 5,700 to >9,999 cps over 6.5 metres)
- 300 to 490 cps over 2 metres, starting at 119 metres.
The 50/50 joint venture partners stated the mineralization “may have been derived from a high-energy erosion of mineralization exposed at the top of a body of basement mineralization on the floor of the Devonian sea. It does not have the characteristics of hydrothermal mineralization such as is seen in the basement mineralization elsewhere.”
Alpha’s news release added, “The Devonian cover appears to be patchy and the uranium boulders in the boulder field down ice did not show any evidence of association with Devonian sandstone lithologies. This is significant as it opens the possibility that the source of the uranium boulders may be located in a nearby window in the Devonian veneer where basement mineralization was scoured by the overriding till sheet as it was pushed towards the west-southwest by the ice. The uranium mineralization encountered to date in the three zones of high-grade mineralization was not the source of the large uranium boulder field down ice.”
The boulder train discovery, announced in summer 2011, brought assays up to 39.6% uranium oxide (U3O8). Since then drilling has attempted to find the motherlode that spawned the glacial migration.
UEX releases Shea Creek drill results, updates Douglas River and Hidden Bay
UEX Corp TSX:UEX announced the first five holes from Shea Creek’s summer program on August 6 and also provided updates about its Douglas River and Hidden Bay projects.
Results came from downhole probes measuring gamma radiation, with two holes in the Kianna East zone finding basement mineralization. Hole SHE-142 was drilled to a total downhole depth of 1,056 metres, reaching the unconformity at 726.5 metres:
- 0.2% uranium oxide-equivalent (eU3O8) over 3.4 metres, starting at 885.3 metres in downhole depth
- (including 0.35% over 1.2 metres)
- 0.34% over 2.9 metres, starting at 907.9 metres
- 0.85% over 22.3 metres, starting at 915.2 metres
- (including 1.14% over 8.8 metres)
- (which includes 5.93% over 1.4 metres).
Hole SHE-142-1 reached 1,083 metres in downhole depth, striking the unconformity at 727.4 metres:
- 0.23% over 1.6 metres, starting at 939.4 metres.
True widths were unavailable. Hole SHE-142 expands the zone approximately 15 metres east of the previously reported SHE-118-24 that found 1.55% eU3O8 over 19.9 metres starting at 943.7 metres, the company stated. Mineralization remains open east and southeast of SHE-142. Hole SHE-142-1 stepped out approximately 35 metres north of SHE-118-24.
Three holes sunk in the Anne South zone to test a prospective conductor found no significant results. UEX holds a 49% interest in the Shea Creek JV, in which AREVA Resources Canada acts as project operator. The companies have now incorporated their 49%/51% Douglas River JV into the Shea Creek project, saying mineralization extends from Shea Creek’s northern boundary into the contiguous Douglas River property. Shea Creek sits about nine kilometres south of the former Cluff Lake mine, a 22-year operation that produced over 64 million pounds of U3O8.
The Athabasca Basin’s third-largest resource after Cameco Corp’s TSX:CCO McArthur River and Cigar Lake, Shea Creek’s April update showed:
- an indicated category of 2.07 million tonnes averaging 1.48% for 67.66 million pounds U3O8
- an inferred category of 1.27 million tonnes averaging 1.01% for 28.19 million pounds.
UEX also announced it has shelved its 100%-held Hidden Bay project until spot and long-term uranium prices pick up. In February 2011 the company issued a preliminary economic assessment for the eastside Basin property’s Horseshoe and Raven deposits.
Western Athabasca Syndicate begins PLS-area fieldwork ahead of schedule
Backed by a four-company strategic alliance, fieldwork has begun on the PLS-area’s largest land package. On August 8 Skyharbour Resources TSXV:SYH, Athabasca Nuclear TSXV:ASC, Lucky Strike Resources TSXV:LKY and Noka Resources TSXV:NX announced completion of VTEM plus and radiometric surveys over their Western Athabasca Syndicate Project. After an initial review the companies decided on immediate follow-up work.
The package totals 287,130 hectares, with 275,361 hectares in the vicinity of the Fission/Alpha near-surface, high-grade discovery. On reviewing early survey data, the alliance expanded the survey for a total of 4,840 line-kilometres of VTEM plus and 4,400 line-kilometres of radiometrics to search for conductive anomalies, boulder trains and in-situ mineralization. The surveys focused on the syndicate’s Preston Lake property just south, southeast and west of PLS.
“Originally we were planning on having a field crew up there later in August,” Skyharbour president/CEO Jordan Trimble tells ResourceClips.com. “Now we’ve decided to send them up this weekend because we’re very, very encouraged with what we’ve seen initially.”
One area of Preston Lake especially caught their attention. “There were quite a few targets but this one really lit up,” Trimble says. “So we made the decision to expedite the program and begin the fieldwork immediately. We’ll be employing the same techniques that worked for Alpha and Fission.”
While geophysicist Phil Robertshaw works out a more detailed interpretation of the airborne surveys, ground work will consist of water and soil radon sampling, biogeochemistry, lake sediment and soil sampling, prospecting and scintillometer surveying.
“By the end of September or early October we’ll have spent $1.5 million, with each company contributing towards its 25% earn-in. The four companies with their respective geological teams are working harmoniously on this,” he adds.
“We’re now focused on the northern part of Preston Lake, but we have a large land package. As a four-company syndicate we have more ability to finance and explore. There’s certainly a lot of blue sky potential elsewhere on our properties.”
The current phase should last until early October, he explains. “Then we’ll decide what to do in the fall. There’s still a lot of work that can be done that time of year. Obviously we don’t want to drill just anywhere but if we can get definitive drill targets by then, winter would be the ideal time to drill. The earlier we can get these targets, the better. And that’s the goal.”
Combined, the four companies have agreed to fund $6 million of exploration over two years. Athabasca Nuclear acts as project operator.
