Denison reports best grade/interval result from high-grade Wheeler River
A radiometric probe has found the most impressive result so far from Denison Mines’ TSX:DML Wheeler River project in the eastern Athabasca Basin. Of four holes reported July 24, one showed the project’s highest grade-times-thickness calculation.
Three holes at the Phoenix A deposit showed:
- 43.2% uranium oxide-equivalent (eU3O8) over 10.3 metres, starting at 401.6 metres in vertical depth
- 16.4% over 1.7 metres, starting at 403.5 metres
- 13% over 3.1 metres, starting at 403.7 metres.
Roughly 2.1 kilometres from the Phoenix deposits, one hole at the 489 zone showed:
- 0.3% over 3.2 metres, starting at 411.1 metres.
Intercepts are approximate true widths. The company explained eU3O8 as “radiometric equivalent uranium oxide calculated from a total gamma downhole probe.” Radiometric probes are not chemical assays.
The Phoenix A drill holes tested for possible extensions of the deposit’s higher-grade domain, defined as approximately 20% U3O8. Using a 0.8% cutoff, the December 2012 resource estimate for Phoenix A showed:
- an indicated category of 133,500 tonnes averaging 15.8% for 46.5 million pounds U3O8
- an inferred category of 6,300 tonnes averaging 51.7% for 7.2 million pounds.
With the same 0.8% cutoff, the Phoenix B deposit showed:
- an indicated category of 19,000 tonnes averaging 14.1% for 5.9 million pounds
- an inferred category of 5,300 tonnes averaging 3.5% for 400,000 pounds.
Combined, Wheeler River’s resource comes to 52.4 million pounds indicated and 7.6 million pounds inferred.
This summer will also see Denison busy at seven other Basin properties: Waterbury Lake (held 40% by the Korea Electric Power Corp), Packrat, South Dufferin, Johnston Lake and Moon Lake (held 45% by Uranium One TSX:UUU, which is expected to be taken private by the Russian state-owned company ARMZ in Q3).
WASP extends VTEM-Plus, advances radiometrics on PLS-area’s largest package
A four-company strategic alliance announced progress on its airborne surveys over the Patterson Lake South-area’s largest land package. Jointly funded by Skyharbour Resources TSXV:SYH, Athabasca Nuclear TSXV:ASC, Lucky Strike Resources TSXV:LKY and Noka Resources TSXV:NX, the Western Athabasca Syndicate Project totals 287,130 hectares, with 275,361 hectares in the vicinity of the near-surface, high-grade PLS discovery of Alpha Minerals TSXV:AMW and Fission Uranium TSXV:FCU.
A VTEM-Plus survey has flown 720 line-kilometres in addition to the original 4,120-line-kilometre survey. The additional coverage consisted of infill and extension of conductive anomalies and structural features identified in preliminary data, the syndicate reported on July 23. Meanwhile Goldak Airborne Surveys is wrapping up a 4,400-line-kilometre radiometric program at 200-metre line spacing to measure radioactivity in outcrops and boulder trains. Goldak compiles the data using a proprietary digital acquisition system.
“We should have complete interpretation done by [geophysicist] Phil Robertshaw in early or mid-August,” Skyharbour president/CEO Jordan Trimble tells ResourceClips.com. “That will delineate the highest-priority targets for fieldwork but we’ve already had boots on the ground doing some preliminary surveying and prospecting. We plan to have a small team back there in early August and that will lead to the full-fledged field program that will commence probably in late August.”
With the four companies earning 25% each, the alliance plans to spend $6 million over two years. “The syndicate is a real advantage to budget,” Trimble points out. “Skyharbour’s obligation is just one-sixth of that. The same with Athabasca Nuclear and then Lucky Strike and Noka pay just one-third each, so it’s not onerous for any one company. It makes the project a lot more viable, especially in these tough markets. And we’re really starting to see the synergies pay off here with the different geologists and their contact base. Their networks are open too.”
VTEM-Plus, radiometric collaboration flies Aldrin’s Triple M
The VTEM-Plus and radiometric surveys also cover PLS-area properties held by Aldrin Resource TSXV:ALN and Forum Uranium TSXV:FDC, a money-saving collaboration announced in May. On July 24 Aldrin also reported the program completed VTEM-Plus infill lines and began radiometrics using 100-metre line spacing over its Triple M property.
Scheduled for August is radon sampling as well as follow-up work on any anomalies found by the radiometrics. The company hopes to start drilling next January to test basement conductors reported in June.
NexGen expands PLS-adjacent Rook 1 drill campaign
NexGen Energy TSXV:NXE has doubled its drill plans for Rook 1, the company announced July 24. With two rigs scheduled to start in mid-August, the campaign now calls for approximately 20 holes totalling 3,000 metres, twice the amount announced in May. Land-based, shallow drilling will test targets identified by airborne VTEM and ground gravity and DC resistivity surveys in the property’s southwestern section, immediately northeast of PLS. NexGen interprets a conductor to extend from the Fission/Alpha discovery into southwestern Rook 1.
Fission, Azincourt announce summer program for Patterson Lake North
Immediately north of Patterson Lake South lies, of course, Patterson Lake North. On July 22 joint venture partners Fission and Azincourt Uranium TSXV:AAZ announced a $530,000 summer program to start in early August.
Following up on “conductive areas of interest” found by a previous survey, an airborne VTEM max will fly 303 line-kilometres at 400-metre line spacing over the approximately 25,000-hectare property’s northern half. That will be followed by a single-line 6.3-line-kilometre ground magnetotellurics survey. The property’s southern portion will get a ground TDEM survey. The partners hope results will help identify targets for a drill campaign anticipated for next winter.
The companies say PLN sits within a large gravity low structural corridor that incorporates PLS, the former Cluff Lake mine and the Shea Creek deposits of UEX Corp TSX:UEX and AREVA Resources Canada. Additionally PLN shows EM anomalies that might be interpreted as an extension of the Saskatoon Lake EM conductor associated with Shea Creek.
Azincourt may earn 50% of PLN by paying $4.75 million in cash or shares and spending $12 million by April 2017. Fission gets a 2% NSR and acts as project operator. Fission has already spent about $4.7 million exploring PLN. Earlier this month the company applied for a patent on its “System and Method for Aerial Surveying or Mapping of Radioactive Deposits.”
