Radiometric results divert NexGen’s focus to new area of Rook 1

Following up on last week’s market-moving news, NexGen Energy TSXV:NXE reported more radiometric readings from the first hole on the Arrow area of its Rook 1 project. Obviously inspired by the results, the company has moved its other rig to Arrow “until additional rigs can be sought to drill the other 11 western-located Rook 1 target areas,” according to the February 24 statement.

Once again NexGen has found dozens of “significant”—if tiny—intervals of uranium mineralization from hole RK-14-21. By “significant,” NexGen means at least 0.05 metres reading over 500 counts per second, a measure of gamma radiation from drill core by a hand-held scintillometer. The significant readings started at 207.8 metres in downhole depth and ended at 583.55 metres. Drilling stopped at 663 metres. Two intervals maxed out the scintillometer at 10,000 cps.

Radiometric results from a single hole have turned
NexGen’s attention to the Arrow area of Rook 1.

The readings are no substitute for assays, which are pending. But an additional spectrometer scan “confirmed that all radiometric activity is due to uranium, with minimal or no thorium input.” Further encouragement came from three intercepts showing visible pitchblende.

Now in progress are two more holes, one collared from the same location but at a more shallow angle and another 30 metres northeast along strike. Now under revision is the company’s original 6,000-metre plan for the Patterson Lake South-adjacent project. Arrow has become the target.

On February 26 NexGen reported it closed a previously announced two-year extension to its 70% earn-in on the northeastern Athabasca Basin Radio project. Assays have yet to be released from Radio’s nine-hole, 3,473-metre program, which wrapped up last July.

Denison reports Wheeler River drill results, updates other projects

A downhole radiometric probe found high-grade uranium oxide-equivalent results for a new batch of holes at Denison Mines’ (TSX:DML) flagship Wheeler River project. The company holds a 60% interest and acts as operator in the southeastern Basin joint venture, with Cameco Corp TSX:CCO holding 30% and JCU (Canada) Exploration 10%. Collars for eight holes released February 26 were spaced over roughly 240 metres of the closely drilled zone A of the Phoenix deposit. The best intercepts show:

Hole WR-548

  • 29.61% uranium oxide-equivalent (eU3O8) over 6.5 metres, starting at 407.9 metres in vertical depth

Hole WR-550

  • 18.37% over 4.7 metres, starting at 407.3 metres

Hole WR-545

  • 16.98% over 3.1 metres, starting at 403.3 metres

Hole WR-539

  • 11.63% over 3.5 metres, starting at 401.6 metres

Hole WR-538

  • 2.14% over 5.1 metres, starting at 392.4 metres

  • 0.87% over 3.3 metres, starting at 403.8 metres

  • 1.36% over 1.4 metres, starting at 408.2 metres

  • 0.11% over 2.1 metres, starting at 426.4 metres

With vertical drilling and “roughly” horizontal mineralization, the company considers intercept widths equal to true widths. Assays will presumably follow these radiometric readings, which are no substitute for lab work.

So far 13 of 28 winter holes have been finished at zone A and an exploration target called the K zone. The latter showed no significant mineralization but Denison declared itself encouraged by “sandstone and basement alteration in three of seven wide-spaced drill holes, which will likely warrant follow-up drilling.” This winter rigs will also target Wheeler’s 489 zone, Phoenix North, K North and two DC resistivity-low anomalies, the company added. The project lies about 35 kilometres from the Key Lake mill.

In other Denison updates reported February 26, 10 holes at Hatchet Lake failed to find significant mineralization. The company will evaluate geochemical data before planning further work.

Ten holes at Moore Lake followed Hatchet’s example. Electromagnetic and DC resistivity surveys are slated for winter. Denison currently has drills turning at its Park Creek, Bell Lake and Waterbury Lake projects in campaigns scheduled for March completion.

Kivalliq announces ore-sorting and metallurgical progress at Angilak in Nunavut

Kivalliq Energy TSXV:KIV says metallurgical and ore-sorting tests from the Lac 50 deposit of its Angilak property provide encouraging news for the Nunavut project’s economics. Announced February 27, tests showed better than 95% uranium recovery in a 48-hour leach cycle, the ability to recycle all the primary alkaline leach reagents and production of 70% yellowcake meeting industry standards for uranium concentrate. The presence of boron and magnesium was “marginally higher than penalty levels but significantly below reject levels,” the company stated. Optimization tests continue.

Dilution could be reduced through radiometric ore sorting prior to milling. Tests showed a cumulative uranium recovery of 96.7% out of 49.2% of the extracted rock. In other words, 50.8% of the rock was rejected with loss of only 3.3% of uranium. The tests also showed 94.1% recovery from just 15.9% of the rock, when 84.1% of rock was rejected with a loss of only 5.9% of uranium.

“The testing reflects the high-grade uranium characteristics at Lac 50 where the majority of uranium mineralization occurs as disseminations and veins of massive pitchblende within the carbonate and hematite alteration zone” comprising the inferred resource, the company stated.

The resource boasts Canada’s highest grade outside the Athabasca Basin. Released in January 2013, the inferred category uses a 0.2% cutoff to show 2.83 million tonnes averaging 0.69% for 43.3 million pounds uranium oxide (U3O8). The inferred resource also shows 1.88 million ounces silver, 10.4 million pounds molybdenum and 15.6 million pounds copper. Kivalliq operates the 137,699-hectare project, 225 kilometres south of the hamlet of Baker Lake, in partnership with Nunavut Tunngavik Inc.

Kivalliq picked up another Nunavut property in October and moved into Saskatchewan last January.

Forum starts 3,000 metres at Clearwater

Adjacently southwest of PLS, drilling has begun at Forum Uranium’s (TSXV:FDC) 9,910-hectare Clearwater project. According to its February 26 statement, the company plans about 3,000 metres in 12 to 15 shallow holes between 100 and 200 metres in depth. Around 11 targets were chosen by previous surveys including ground gravity, airborne EM and radon work.

Initial drilling will focus on the project’s northern claim. Forum stated the central and southern claims require further ground gravity, ground EM and radon surveys to define targets.

The previous week Forum’s portfolio increased with the Fir Island acquisition east of Stony Rapids on the Athabasca Basin’s northeastern rim.

Lakeland Resources offers $2 million private placement for Basin exploration

Lakeland Resources TSXV:LK announced a private placement up to $2 million on February 24. The offer consists of three million flow-through units at $0.25 and 5.92 million non-flow-through units at $0.21. Each flow-through unit consists of one flow-through share and one-half non-flow-through warrant. Each warrant is exercisable for 12 months at $0.30. Non-flow-through units consist of one share and one warrant, also exercisable at $0.30 for a year.

Proceeds go to Athabasca Basin exploration, corporate development and general and administrative purposes.

In January Lakeland announced its 12,771-hectare Gibbon’s Creek project showed high-grade boulders up to 4.28% U3O8 and some of the highest radon readings ever measured in the Basin. As part of a 70% four-year earn-in, Declan Resources TSXV:LAN has committed $1.25 million to exploration this year.

Fission and Alpha sign acquisition agreement, Denison challenges Mega for Rockgate

Another burst of merger and acquisition activity hit the markets last week. Joint September 18 statements from Fission Uranium TSXV:FCU and Alpha Minerals TSXV:AMW announced a definitive agreement for the former’s acquisition of the latter. The proposed Mega Uranium TSX:MGA/Rockgate Capital TSX:RGT merger, however, took a surprising turn with Denison Mines’ TSX:DML unsolicited pitch for Rockgate. Denison’s September 17 announcement claimed a 38% premium over Mega’s offer, based on the previous day’s closing prices.

In addition to taking a run at Rockgate, Denison filed a revised
43-101 report for six deposits on its Mutanga property in Zambia.

The Fission/Alpha rationale is to put their 50/50 joint venture under a single owner, creating a company solely focused on Patterson Lake South and presumably a more attractive takeover target. Their other properties would go to two newly created spincos. Should Denison’s offer succeed, the company would spin out its African assets along with Rockgate’s advanced-stage Mali project. That would leave Denison focused on the Athabasca Basin.

Read more about these proposals and other uranium M&A news.

(Update: On September 24 Rockgate terminated its proposed merger with Mega. Read more.)

PLS assay backlog grows as Fission/Alpha release more scintillometer results

Step-out drilling confirmed strong mineralization in Patterson Lake South’s newest zone, Alpha and Fission stated on September 16. The JV partners released scintillometer readings for two new holes on zone R945E, the fourth of four zones along a 1.02-kilometre southwest-northeast trend.

The hand-held device measures drill core gamma rays in counts per second, up to an off-scale reading above 9,999 cps. The results are no substitute for assays, which are pending.

Hole PLS13-092 was collared roughly 10 metres north of existing holes. It reached a total downhole depth of 377 metres, striking the basement unconformity at 59 metres without encountering sandstone. Some highlights include:

  • <300 to 1,400 cps over 3 metres, starting at 157.5 metres in downhole depth

  • <300 to >9,999 cps over 16 metres, starting at 163 metres

  • <300 to 1,800 cps over 11 metres, starting at 192.5 metres

  • 460 to 2,500 cps over 2.5 metres, starting at 238 metres

PLS13-096 was collared about 15 metres grid west of PLS-084, replacing it as the zone’s most southwesterly hole. It found no sandstone, hit the basement unconformity at 56.5 metres and stopped at 365 metres. Highlights include:

  • <300 to >9,999 cps over 42.5 metres, starting at 135.5 metres in downhole depth

  • 310 to >9,999 cps over 11.5 metres, starting at 185.5 metres

  • <300 to >9,999 cps over 10.5 metres, starting at 235.5 metres

  • <300 to >9,999 cps over 14.5 metres, starting at 249 metres

True widths weren’t available. The two holes were drilled at -88 and -89 degree angles respectively, making downhole depths close to vertical.

The $6.95-million program calls for 44 holes totalling 11,000 metres, along with geophysics. These results bring the summer’s drilling to 27 holes totalling 8,488 metres. So far just one of the holes has had lab assays released. Scintillometer readings have been reported for 18 holes this summer.

Denison files combined resources for Mutanga property in Zambia

Denison has filed a new NI 43-101 report to replace two previous reports for its Mutanga property in Zambia, the company announced on September 16. The New Mutanga Report follows an Ontario Securities Commission review of a resource filed in March 2012 for the property’s Dibwe East deposit. The OSC declared that report non-compliant because it didn’t include all resource estimates and material information for the property as a whole. Denison’s new report incorporates information covered in a 2009 report on the Mutanga and Dibwe deposits, as well as the 2012 info for Dibwe East.

Of the project’s six deposits, only Mutanga shows measured, indicated and inferred categories. Mutanga Extension, Mutanga East, Mutanga West, Dibwe and Dibwe East have inferred pounds only. Combined, the estimate shows:

  • a measured resource of 1.88 million tonnes averaging 0.048% for 2 million pounds uranium oxide (U3O8)

  • an indicated resource of 8.4 million tonnes averaging 0.031% for 5.8 million pounds

  • inferred resources totalling 65.2 million tonnes averaging 0.029% for 41.4 million pounds

The 457.3-square-kilometre property is about 200 kilometres south of the capital city of Lusaka, near the Zimbabwean border.

The previous week, Denison updated two Athabasca Basin projects with a new resource for Waterbury Lake and more high-grade assays from Wheeler River.

Lakeland Resources options gold project to focus on Athabasca uranium

Now a pure play uranium explorer, Lakeland Resources TSXV:LK optioned a north-central Ontario gold property to New Dimension Resources TSXV:NDR, the companies announced September 16. New Dimension may earn a 70% interest in the Midas project by paying $100,000, spending $1.2 million and issuing 1.5 million shares. New Dimension must spend $300,000 on exploration by December 31.

We’re maintaining our focus on uranium, yet we’re not giving away what could turn out to be a valuable asset in the end. In our view there’s no downside to our shareholders, only a potential upside.—Roger Leschuk, corporate communications manager for Lakeland Resources

The 2,112-hectare road-accessible property has already seen ground magnetics, induced polarization and 16 drill holes that partially defined two gold-bearing zones, with 14 holes showing gold mineralization. Among the assays was 5.92 grams per tonne gold over 4.7 metres, starting at 45.7 metres in depth and including 8.88 g/t over 2.6 metres.

“We get to maintain an interest in a property that looks very encouraging to say the least,” Lakeland corporate communications manager Roger Leschuk tells “The people who are picking it up are a very good group and they see this as potentially becoming their flagship property. The great part about it for Lakeland is we retain a 30% interest all the way potentially to a new discovery. We’re maintaining our focus on uranium, yet we’re not giving away what could turn out to be a valuable asset in the end. In our view there’s no downside to our shareholders, only a potential upside.”

A fall drill program is expected to begin shortly, the companies stated.

Forum announces fall/winter plans for its PLS-adjacent Clearwater project

In a September 17 report, Forum Uranium TSXV:FDC updated its Clearwater project, which underwent ground radiometric prospecting, lake sediment geochemical surveys and soil radon surveys in late August and early September. The radon survey found anomalous zones immediately southwest of the adjacent PLS property, the company stated. Forum now plans further prospecting of radiometric anomalies, as well as an expanded radon survey to cover areas with electromagnetic conductors on strike with the PLS conductive trend. Autumn is scheduled for ground EM surveys and early winter for ground gravity work to identify drill targets for the 9,910-hectare property in late January.

One week earlier Forum said its private placement raised $2.59 million.
