Alpha/Fission extend one PLS zone, disagree about certainty of a “fifth zone”
The news from Patterson Lake South continues to impress—even when the joint venture partners don’t interpret it quite the same way. Fission Uranium TSXV:FCU says a 150-metre step-out found a “fifth high-grade zone.” Alpha Minerals TSXV:AMW prefers to call it a “potential” fifth high-grade zone. Either way, the September 23 news was one of three announcements last week that included an extension to an existing zone’s strike length.
The new or potential new zone sits about halfway between the R390E and R780E zones, which are either the second and third of four zones, or the second and fourth of five zones, along a 1.02-kilometre southwest-northeast trend. With luck future drill results will bring Alpha into agreement with Fission, thereby simplifying sentence structure.
Hole PLS13-085 was collared 150 metres grid east of R390E, reached a depth of 317 metres and struck the basement unconformity at 62.4 metres without encountering sandstone. Preliminary results come from a hand-held scintillometer, which measures radiation up to an off-scale level of more than 9,999 counts per second. Scintillometer readings are no substitute for assays, which are pending. Some highlights showed:
- <300 to >9,999 cps over 33.5 metres, starting at 67 metres in downhole depth
- <300 to 2,200 cps over 9.5 metres, starting at 111 metres
- <300 to >9,999 cps over 16.5 metres, starting at 123 metres
- <300 to >9,999 cps over 9.5 metres, starting at 160.5 metres
True widths weren’t available. With a -89 degree dip, downhole depths were close to vertical depths.
Two days later, and with greater unanimity, the 50/50 partners released assays for holes that had previously reported scintillometer readings. Ranking as one of the best PLS holes so far, PLS13-072 reached a total depth of 209 metres. It found no sandstone and struck the basement unconformity at 55.7 metres. Some highlights include:
- 8.15% uranium oxide (U3O8) over 34.5 metres, starting at 61 metres in downhole depth
- (including 19.28% over 7.5 metres)
- (and including 21.53% over 4 metres)
- 0.58% over 11 metres, starting at 98.5 metres
- 0.57% over 8.5 metres, starting at 125 metres
- (including 1.61% over 2.5 metres)
- 2.22% over 6.5 metres, starting at 137 metres
- (including 10.65% over 1 metre)
With an -89 degree dip, the depths were close to vertical.
PLS13-073 struck sandstone at 50 metres and the basement unconformity at 53 metres, before stopping at 248 metres. Some highlights include:
- 0.25% over 19.5 metres, starting at 102 metres in vertical depth
- (including 0.92% over 3 metres)
- 0.59% over 10 metres, starting at 132.5 metres
- (including 4.81% over 1 metre)
True thicknesses are still to come.
When their scintillometer readings were reported earlier (here and here), the two holes extended R390E’s strike 15 metres grid west and 15 metres grid east respectively. But on September 27 the JV announced a further extension, bringing the zone’s strike to about 255 metres and suggesting the possibility “of extending the zone south along the entire length of the corridor as it becomes further delineated.” Here are some highlights from the eight holes reported:
Hole PLS13-087A reached a total depth of 227 metres, encountering sandstone at 50 metres and the basement unconformity at 50.9 metres.
- <300 to >9,999 cps over 14.5 metres, starting at 68.5 metres in downhole depth
- <300 to 2,100 cps over 17 metres, starting at 98 metres
Hole PLS13-088 reached a total depth of 296 metres, encountering sandstone at 53 metres and the basement unconformity at 54.3 metres.
- <300 to 9,800 cps over 23.5 metres, starting at 80 metres in downhole depth
- 400 to 8,100 cps over 8 metres, starting at 135 metres
Hole PLS13-094 reached a total depth of 272.3 metres, encountering sandstone at 50.7 metres and the basement unconformity at 53.4 metres.
- <300 to >9,999 cps over 12 metres, starting at 130 metres in downhole depth
Hole PLS13-095 reached a total depth of 275 metres, encountering sandstone at 47.6 metres and the basement unconformity at 51.7 metres.
- <300 to >9,999 cps over 11.5 metres, starting at 68 metres in downhole depth
- <300 to >9,999 cps over 7 metres, starting at 93.5 metres
- <300 to 5,800 cps over 33 metres, starting at 116 metres
Hole PLS13-100 reached a total depth of 263 metres, encountering sandstone at 53 metres and the basement unconformity at 53.3 metres.
- 790 to >9,999 cps over 6 metres, starting at 53 metres in downhole depth
- <300 to 8,000 cps over 20 metres, starting at 99.5 metres
- <300 to>9,999 cps over 8.5 metres, starting at 134 metres
Hole PLS13-102 reached a total depth of 275 metres, encountering sandstone at 58.3 metres and the basement unconformity at 58.8 metres.
- <300 to 6,000 cps over 29 metres, starting at 103 metres in downhole depth
- <300 to >9,999 cps over 10.5 metres, starting at 137.5 metres
Again, true thicknesses were unavailable. With dips ranging from -84 to -89 degrees, downhole depths were close to vertical. Assays are pending for these holes but this summer’s drilling has extended R390E more than four-fold from last winter’s 60-metre strike.
Fission acts as project operator on the current $6.95-million program. On September 18 the partners signed a definitive agreement for Fission’s acquisition of Alpha and sole control over PLS, with the companies’ other assets to be spun out into two separate companies.
Rockgate rejects Mega merger, mulls Denison deal and other possibilities
Just one day before their shareholders were to vote on a merger with Mega Uranium TSX:MGA, Rockgate Capital TSX:RGT directors scuttled the proposal. Although a “superior” offer from Denison Mines TSX:DML led to their September 24 announcement, Rockgate directors expressed reservations, said they needed more time for due diligence and expressed interest in receiving other offers.
Rockgate delineates Falea project’s 880 zone in Mali
Meanwhile work continues on the object of those affections, Rockgate’s Falea flagship in southwestern Mali. On September 26 the company released assays from four holes on the 880 zone, which was discovered last fall. The results show:
- 0.59% U3O8, 45.7 grams per tonne silver and 0.17% copper over 2.7 metres, starting at 301.4 metres in downhole depth
- 0.06% U3O8, 118.3 g/t silver and 0.78% copper over 2 metres, starting at 303 metres
- 0.12% U3O8, 86.3 g/t silver and 0.52% copper over 3 metres, starting at 320 metres
- 0.17% U3O8, 17.1 g/t silver and 0.16% copper over 4 metres, starting at 304.5 metres
- (including 1.13% U3O8, 96 g/t silver and 1.14% copper over 0.5 metres)
Intercepts are estimated at 96% to 100% of true widths. Mineralization remains open in several directions, the company stated.
This year’s 19-hole, 5,910-metre program included 14 holes totalling 4,563 metres on the 880 zone’s 500-metre strike length. Another five holes totalling 1,347 metres tested the project’s Central zone. The 880 zone has yet to be included in Falea’s resource estimate. Released last December, it shows:
- a measured category of 1.39 million tonnes averaging 0.14% U3O8 for 4.29 million pounds U3O8, with 3.52 million ounces silver and 6.05 million pounds copper
- an indicated category of 14.28 million tonnes averaging 0.08% U3O8 for 25.29 million pounds U3O8, with 24.43 million ounces silver and 68.17 million pounds copper
- an inferred category of 15.35 million tonnes averaging 0.05% U3O8 for 15.69 million pounds U3O8, with 8.91 million ounces silver and 81.19 million pounds copper
Rockgate plans to incorporate the 880 zone into an updated resource, likely to coincide with a pre-feasibility study scheduled for completion early next year. The company says it’s been “entirely unaffected” by last year’s military coup and this year’s fighting between French troops and al-Qaida-linked rebels.
NexGen completes two-thirds of Rook 1 drilling, awaits Radio assays
NexGen Energy TSXV:NXE updated its PLS-adjacent Rook 1 drill campaign September 25. With 3,000 metres planned, the company has sunk eight holes totalling 1,957 metres on an area about 700 metres along interpreted extensions of the PLS 3B conductor and a parallel conductor approximately 800 metres east.
“All holes intersected varying types of structural zones in basement lithologies, ranging from small fractures through to wide, heavily brecciated material,” the company stated. Scintillometer readings found intercepts of elevated levels in several holes, while all eight holes reached shallow basement rock at downhole depths ranging from 48.7 metres to 82.6 metres. Weather permitting, drilling will continue to October. Winter drilling is planned for the same area.
Assays are still pending from NexGen’s nine-hole, 3,473-metre campaign at Radio, where the company holds a 70% option two kilometres east of Rio Tinto’s NYE:RIO Roughrider deposits on the northeastern Basin. In late August NexGen closed $5 million in private placements.
Canadian International Minerals options two claim groups to Rio Grande;
Rio Grande offers $900,000 private placement, grants options
Canadian International Minerals TSXV:CIN announced on September 24 it optioned Rio Grande Mining TSXV:RGV a 75% interest in the Britts Lake East and Firebag East/Descharme claims about 35 kilometres southwest of PLS. Under the agreement Rio Grande would pay a total of $100,000 and issue Canadian International 500,000 shares. Rio Grande would also spend $250,000 by year one, $500,000 by year two and $1.5 million by year three. The companies didn’t specify whether those are aggregate or separate yearly figures.
Canadian International retains a 2% NSR, of which Rio Grande may buy half for $1 million. Canadian International will act as project operator on a planned winter campaign to include radon and helium surveys, as well as lake sediment sampling on the 18,041-hectare package.
Canadian International also holds a 50% interest in each of two other Saskatchewan uranium prospects, the 4,639-hectare Coflin Lake property and the 34,762-hectare Clearwater property.
On September 25 Rio Grande announced a private placement of up to $900,000, consisting of six million units at $0.10 and another 2.5 million units at $0.12. The company also granted 900,000 options to insiders at $0.12 for five years.
Western Athabasca Syndicate reports radon and radiometric anomalies at Preston Lake
A four-company strategic alliance focused on the PLS area’s Western Athabasca Syndicate project reported anomalous radon and scintillometer findings on September 26. Skyharbour Resources TSXV:SYH, Athabasca Nuclear TSXV:ASC, Noka Resources TSXV:NX and Lucky Strike Resources TSXV:LKY stated an initial radon-in-water survey found nine of 291 samples measuring over 23 picocuries per litre, with the highest reaching 98 pCi/L. The anomalies appear as both clusters and discrete point anomalies, the companies added. Fission and Alpha based their initial PLS drill targets on these measurements of radon gas.
Additionally, WASP’s 217-kilometre scintillometer survey found 25 areas radiating over 1,000 cps, more than twice the typical background level. More Phase II results are pending while Phase III field work continues with the intention of identifying drill targets.
