Fission Uranium stretches strike with new zone at Patterson Lake South, closes $28.75-million financing

Step-out drilling has added a new zone to Fission Uranium’s (TSXV:FCU) Patterson Lake South, shortly after infill drilling had merged other zones. Announced March 31, zone R1620E lies 465 metres east of R1155E, extending the project’s potential strike from 1.78 kilometres to 2.24 kilometres.

The results come from a hand-held scintillometer that measures gamma radiation from drill core in counts per second. Scintillometer readings are no substitute for assays, which are pending.

Uranium news from Saskatchewan and elsewhere for March 29 to April 4, 2014

The road to Patterson Lake South, where Fission has four
of its five rigs trying to merge zones into one big deposit.

Six new holes all showed mineralization, with the new zone’s inaugural hole, PLS14-196, revealing a 30-metre interval ranging between 300 cps and 6,100 cps starting at 99 metres in downhole depth. The maximum that the scintillometer can measure is 9,999 cps. Drilling on PLS14-196 continues.

Among other holes, PLS14-190, south of zone R1155E, “suggests that further step-outs to the south may be prospective,” the company stated.

Starting from the west, zone R600W has both a 30-metre east-west strike and a 30-metre north-south lateral width. About 510 metres east, discovery zone R00E has a strike of approximately 165 metres and a lateral width up to about 45 metres. Another 135 metres east sits R780E, with about 855 metres in strike and up to about 95 metres in lateral width.

Neighbouring 75 metres east, R1155E so far has just three mineralized holes. Fission Uranium declared the new zone, 465 metres east again, on the basis of a single hole over conductor PL-3C, “the suspected 1.3-kilometre-long strike extension of the mineralized PL-3B conductor” at an interpreted cross-fault, the company added.

So far 63 of a planned 100 holes totalling 30,000 metres have been sunk. The winter budget comes to $12 million but on April 1 the company announced its most recent private placement closed with gross proceeds of $28.75 million.

Three days later Fission Uranium granted insiders 6.5 million options at $1.65 for five years.

NexGen’s best-ever hole extends strike at Rook 1’s Arrow zone

NexGen Energy TSXV:NXE ended its Rook 1 winter drill program with a “massive” step-out showing the project’s best hole yet. Results for three holes released March 31 lengthen the strike to about 215 metres, open to the southwest.

The winter campaign comprised 17 holes totalling 7,442 metres, but it wasn’t until late February that the Arrow discovery diverted attention to this new zone of the PLS-adjacent project. A second hole in early March contributed to the company’s optimism. In all, seven of eight Arrow holes so far have found significant mineralization.

The results come from a hand-held spectrometer that measures drill core for radiation in counts per second. As is the case with Fission Uranium’s scintillometer readings, the results are no substitute for assays, which NexGen expects to see in about six weeks.

NexGen reports radiometric readings differently than Fission Uranium, providing a more detailed breakdown of small intercepts.

The step-out, hole RK-14-30, found a composite 47.2 metres (not true widths) of anomalous intercepts at least 0.05 metres wide measuring over 500 cps. A total of 8.3 metres surpassed the spectrometer’s maximum possible reading of 9,999 cps. Mineralization began at 84.15 metres in downhole depth, with the deepest intercept stopping at 701.45 metres.

RK-14-29 also revealed many small intercepts, with the first starting at 50.6 metres in downhole depth and the last ending at 569 metres.

RK-14-28 intercepts started at 87 metres in downhole depth, with the last ending at 549 metres.

Having closed an $11.5-million bought deal the previous week, NexGen now has about $15 million to spend. Spring breakup work will include detailed petrography and petrophysics before drilling resumes in the summer.

Denison drills 17.3% eU3O8 over 4.2 metres at new Wheeler River zone

Denison Mines TSX:DML reported a second hole on April 2 that supports last month’s discovery of the Gryphon zone at the Wheeler River JV. WR-560 was drilled 40 metres along the up-dip extension of the first hole, revealing one especially high-grade interval. The results come from a downhole probe that measures radiation in uranium oxide-equivalent (eU3O8). Although the probe is more accurate than a scintillometer or spectrometer, its readings are no substitute for assays. Nevertheless they show:

  • 0.1% eU3O8 over 1.3 metres, starting at 653.5 metres in downhole depth

  • 0.1% over 4.1 metres, starting at 676.2 metres

  • 17.3% over 4.2 metres, starting at 757.9 metres

  • 0.3% over 2.6 metres, starting at 770.7 metres

True widths are estimated at about 75%. Denison interprets these results “to be a new lens in the footwall, about 50 metres northwest of the high-grade intersection in WR-556,” Gryphon’s discovery hole. Mineralization lies approximately 200 metres beneath the unconformity and remains open in both strike directions and at depth, the company stated.

With spring break-up underway, drilling is expected to resume in early June, largely focusing on the new find. Gryphon is three kilometres northwest of the project’s Phoenix deposit, which produced a batch of drill results in February.

Denison holds a 60% interest in Wheeler and acts as operator. Cameco Corp TSX:CCO holds 30% and JCU (Canada) Exploration the rest.

Declan picks up six Alberta and Saskatchewan properties

Calling it a “six-pack” of new properties, Declan Resources TSXV:LAN announced a package of Alberta and Saskatchewan acquisitions in and around the Basin on April 1. Totalling roughly 101,000 hectares, the properties include Maurice Creek in Alberta, immediately northwest of the Northwest Athabasca project, a JV involving Cameco, Forum Uranium TSXV:FDC and NexGen that hosts the historic Maurice Bay deposit.

Two other Alberta properties, Maybelle North and Richardson River, “cover potential northerly extensions to the structure which is host to a significant uranium deposit at Dragon Lake along the Maybelle River shear zone,” Declan stated.

The other properties are Archer Lake and Jackfish Creek, also in Alberta, and Thorburn Lake in Saskatchewan.

The optioner gets $25,000 and 2.5 million shares on TSXV approval, another $125,000 within a year and a 3% gross overriding royalty with a 1% buyback clause for $1 million. To keep the properties in good standing Declan must spend $225,000 by April 17.

Declan also announced changes to its board, which now consists of David Miller, Wayne Tisdale, Michelle Gahagan, Hikmet Akin, Gordon King, Jamie Newall and Craig McLean.

Declan’s flagship is Gibbon’s Creek, a joint venture with Lakeland Resources TSXV:LK.

International Enexco reports new radiometric results from Mann Lake

The latest hole from its Mann Lake JV suggests the project has at least 300 metres of mineralized trend within the footwall of the western conductor target, International Enexco TSXV:IEC stated April 3. The results come from a downhole radiometric probe and are no substitute for assays.

Sunk 150 metres north of the project’s best interval so far, hole MN-065 showed:

  • an average 3.67% eU3O8 over 1.2 metres, starting at 689.8 metres in downhole depth

  • (including an average 6.51% over 0.7 metres)

  • (which includes an average 11.02% over 0.3 metres)

True widths weren’t available.

So far eight holes have tested about 1.8 kilometres of the target, which the company says remains prospective for its entire 3.1-kilometre length. Enexco anticipates follow-up drilling next winter along the conductor and on other areas. The southeastern Basin project is operated by JV partner Cameco, which holds 52.5%, leaving Enexco with 30% and AREVA Resources Canada 17.5%.

But how long Enexco will be involved depends on the outcome of Denison’s most recent acquisition activities. The two companies signed a letter of intent last month for an all-share deal that would give Denison all of Enexco’s Basin properties while spinning out the others. The companies currently JV on another southeastern Basin property, Bachman Lake.

Uracan/UEX drill results suggest prospective target at Black Lake

Black Lake partners Uracan Resources TSXV:URC and UEX Corp TSX:UEX reported the first six holes from their northern Basin JV on April 2, with one mineralized hole suggesting a new target. BL-148 showed:

  • 0.13% U3O8 over 0.5 metres, starting at 275 metres in downhole depth

  • 0.04% over 0.5 metres, starting at 299.5 metres

  • 0.12% over 1 metre, starting at 317 metres

True widths weren’t provided. The three intervals occur up to 19 metres below a footwall unconformity between the basement and sandstones, representing a mineralization style that “has not been encountered previously in this area of the property and represents a new prospective target,” the companies stated.

Next in line is a ground DC resistivity survey to precede further drilling and field work. Uracan may earn 60% of the 30,381-hectare project from UEX, which holds an 89.99% interest. AREVA Resources Canada holds the remaining 10.01%. UEX acts as operator.

Previous Black Lake drilling has found intervals as high as 0.69% over 4.4 metres, starting at 310 metres in downhole depth, 0.79% over 2.82 metres, starting at 310 metres, and 0.67% over 3 metres, starting at 274 metres.

The property borders Gibbon’s Creek, where JV partners Lakeland and Declan have reported boulder samples grading up to 4.28% and some of the Basin’s highest-ever radon readings.
