Innovation overcomes epic struggle to put Cameco’s Cigar Lake into production

 

 

With an ore grade 100 times the world average, Cameco Corp TSX:CCO overcame tremendous challenges to put Cigar Lake into production. Indeed the project’s first ore shipment on March 13 suggests that high grade is the mother of invention.

Among other tribulations, flooding in 2006 and 2008 stalled the eastern Athabasca Basin mine, which dates back to a 1981 discovery and began construction in 2005. Last year’s planned start-up hit another delay with leaks from tanks built to hold the run-of-mine slurry. Around the same time the McClean Lake mill faced delays of its own with modifications to the leaching circuit.

Cameco devised innovative techniques of bulk freezing and jet boring to extract the deposit lying 410 to 450 metres below surface, “where water-saturated Athabasca sandstone meets the underlying basement rocks.”

Uranium news from Saskatchewan and elsewhere for March 8 to 14, 2014

The jet boring tunnel at Cigar Lake, which Cameco calls “among
the most technically challenging mining projects in the world.”

To prevent flooding, the company freezes the ore and surrounding rock “by circulating a brine solution through freeze holes drilled from both surface and underground.”

To extract the ore, Cameco developed a method of high-pressure water jet boring “after many years of test mining” that keeps operators safely distant from the enormously high-grade deposit.

The company’s targeting 18 million pounds a year at full production, making it the world’s largest high-grade uranium mine after the Cameco/AREVA (70%/30%) McArthur River operation. But even 33 years after Cigar Lake’s discovery, the company anticipates further difficulties: “As we ramp up production, there may be some technical challenges which could affect our production plans.”

As of December 31, Cigar Lake capital expenditures came to $2.6 billion. Over 600 people will staff the mine.

Milling will take place at McClean Lake, 70 kilometres northeast. Operator AREVA Resources Canada says the plant “is expected to produce 770 to 1,100 tonnes of uranium concentrate from Cigar Lake ore in 2014. Its annual production rate will ramp up to 8,100 tonnes as early as 2018.”

Cigar Lake shows proven and probable reserves averaging 18.3% for 216.7 million pounds U3O8. Measured and indicated resources average 2.27% for 2.2 million pounds. The inferred resource averages 12.01% for 98.9 million pounds.

Cigar Lake is a joint venture of Cameco (50.025%), AREVA (37.1%), Idemitsu Canada Resources (7.875%) and TEPCO Resources (5%).

The McClean Lake JV consists of AREVA (70% ), Denison Mines TSX:DML (22.5%) and OURD Canada (7.5%).

Fission Uranium reports Patterson Lake South’s second-best radiometric results, $25-million bought deal

Patterson Lake South’s momentum continued on March 10 as Fission Uranium TSXV:FCU released its third batch of radiometric readings in five days—this time boasting one hole with “the second strongest off-scale results recorded at PLS to date, placing it amongst the best holes drilled in the Athabasca Basin.” The four new holes also continue the winter program’s 100% hit rate and further encourage the company’s quest to connect the six zones along a 1.78-kilometre potential strike.

Fission Uranium reports Patterson Lake South’s second-best radiometric results

Fission uses a hand-held scintillometer to measure
radiation from drill core prior to receiving lab assays.

The most recent star hole is PLS14-164, whose intervals showed a total of 30.08 metres of off-scale readings at 9,999 counts per second, the maximum amount of gamma radiation that the hand-held scintillometer can measure. The readings, taken from drill core, are no substitute for assays, which will follow.

Another hole showed a composite 2.1 metres of off-scale radioactivity. Of the four holes, the mineralized intercept closest to surface started at 56 metres, while the deepest stopped at 380.5 metres.

Oddly enough, Fission Uranium’s March 10 release says one of the new holes “has narrowed the distance between zones R390E and R585E to approximately 60 metres.” That’s the same distance between the same zones reported by the company on March 7.

Already 40 holes have been completed in the $12-million winter campaign that began in mid-January. The company plans about 85 or 90 holes totalling around 30,000 metres on the ice-bound lake before spring. While one rig explores outside the mineralized area, Fission Uranium hopes its four other drills will fill the gaps between the project’s six zones.

Just before the March 10 closing bell Fission Uranium announced a $25-million bought deal. A syndicate of underwriters led by Dundee Securities agreed to buy 15.65 million warrants, exercisable for one share each, at $1.60. The company expects to close the private placement by April 1. The underwriters may buy an additional 15%.

Fission Uranium surpassed its 52-week high March 10, opening three cents above its previous close, reaching $1.71 and then settling on $1.67 when trading was halted at the company’s request minutes before the $25-million announcement.

Trading resumed the following day. The company closed March 14 on $1.59. With 330.12 million shares outstanding, Fission Uranium had a market cap of $524.89 million.

NexGen repeats success with second hole at Rook 1’s new area

NexGen repeats success with second hole at Rook 1’s new area

Core from RK-14-27 shows pitchblende within
brecciated shear at 253.8 metres in downhole depth.

With radiometric results from a second hole on Rook 1’s Arrow prospect, NexGen Energy TSXV:NXE repeated last month’s success. On March 13 the company released dozens of tiny intervals ranging from 0.05 to 0.45 metres that showed “significant” readings over 500 counts per second. One intercept of 15.05 metres (not true width) showed almost continuous significant results.

The measurements, which are no substitute for assays, were obtained by scanning drill core with a hand-held radiation detector.

Significant intervals for RK-14-27 started at 224.45 metres in downhole depth and ended at 435.9 metres. Drilling stopped at 576 metres. About a dozen small intervals hit the device’s maximum possible reading of 10,000 cps. Arrow’s mineralization now extends at least 32 metres down dip across two holes, NexGen stated.

Three other holes failed to find significant radiation but “analysis of structures in these holes meant that hole 27 was successfully planned to intersect the interpreted mineralized zones both along strike and down dip.” The company plans to sink RK-14-29 40 metres southwest along strike. Now in progress, RK-14-28 is testing a gravity low roughly 200 metres west of RK-14-27.

The company has two drills working the Arrow area, now the focus of the PLS-adjacent Rook 1 project. A third rig will join by summer.

On March 10 NexGen stated it filed a preliminary short form prospectus regarding the previously announced $10-million bought deal, which the company expects to close on or about March 26.

Fission 3.0 stakes 42,000 additional hectares in and around the Basin

Three acquisitions and one property expansion add nearly 42,000 hectares to Fission 3.0’s (TSXV:FUU) portfolio. Announced March 13, the newly staked properties indicate “there remain many under-explored areas of the Athabasca Basin,” according to COO and chief geologist Ross McElroy.

Not all the new turf actually lies within the Basin. But neither does PLS. The 20,826-hectare Perron Lake property is about 20 kilometres north of the Basin and has benefited from regional lake sediment sampling that showed strong uranium anomalies.

The 9,168-hectare Cree Bay property sits within the northeastern Basin, where historic airborne geophysics suggest potential for hydrothermal and structure-related deposits.

Within the southeastern Basin, the 4,354-hectare Grey Island property is located about 70 kilometres from Key Lake, the world’s largest high-grade uranium mill.

Manitou Falls enlarges by 7,589 hectares to a total of 10,529 hectares. The northeastern Basin property was originally staked last May when the spinco was just a gleam in Fission Uranium’s eye. Historic data shows six radiometric anomalies and multiple basement electromagnetic conductors.

Fission 3.0’s portfolio now numbers nine Saskatchewan and Alberta properties in and around the Basin and one in Peru’s Macusani uranium district.

Purepoint finds new zone at Hook Lake JV

March 10 news from Purepoint Uranium TSXV:PTU heralded a new zone of mineralization at its Hook Lake joint venture five kilometres northeast of PLS. Although two of four holes failed to find mineralization, the other two prompted the company to move its second rig to the new Spitfire zone.

The single interval released from hole HK14-09 showed:

  • 0.32% uranium oxide (U3O8) over 6.2 metres, starting at 208.9 metres in downhole depth
  • (including 1.1% over 0.5 metres)

Thirty metres northwest, HK14-11 showed:

  • 0.11% over 2 metres, starting at 197.9 metres

  • 0.05% over 3 metres, starting at 201.9 metres

  • 0.57% over 0.9 metres, starting at 210.6 metres

True widths weren’t provided. These holes were drilled at a -70 degree dip.

All four holes targeted the 2.9-kilometre D2 electromagnetic conductor, which features “a large magnetic low, possibly indicative of hydrothermal alteration,” said VP of exploration Scott Frostad. “Now that the D2 conductor has been shown to be associated with uranium mineralization, we will increase our drilling efforts towards the northeast where geophysics suggests there is a more structurally complex setting.”

Purepoint stated D2 comprises part of the Patterson Lake conductive corridor, the same conductive trend targeted by Fission at PLS.

Purepoint holds a 21% interest in the 28,683-hectare project and acts as operator for partners Cameco (39.5%) and AREVA Resources Canada (39.5%). The work is part of a $2.5-million, 5,000-metre campaign that began in late January.

In early February Rio Tinto NYE:RIO began drilling Purepoint’s Red Willow project as part of Rio’s 51% earn-in.

More than $7 billion in mining investments stalled in Colombia

January 22nd, 2014

by Cecilia Jamasmie | January 22, 2014 | Reprinted by permission of MINING.com

Colombia, not long ago one of the favourite destinations for mining enthusiasts, is struggling to keep its resources sector healthy, with about $7.3 billion of expected investments currently stalled due to delays in environmental approvals and decreased demand from overseas.

More than $7 billion in mining investments stalled in Colombia

Over 4,000 mining jobs are on the line due to ongoing suspension of Drummond’s exports. (Photo:

In an interview with local paper Vanguardia.com, Large Scale Mining Association representative Claudia Jimenez blamed regulatory holdups for the declining growth of the sector.

Colombia’s economy, mostly driven by oil and mining, grew 6.6% in 2011 but has steadily declined ever since. That’s partly due to the economic state of its biggest trading partners, mainly the U.S.

But Jimenez—who represents 13 of the largest miners of Colombia, such as Cerrejon, Cerro Matoso, AngloGold Ashanti NYE:AU and Drummond—also thinks the decline is related to the lack of support for companies in the country. She told Vanguardia she hoped the situation would improve rather soon, as the country now has a National Mining Agency, created two years ago.

The Drummond effect

Some analysts believe the recent sanctions against U.S. mining giant Drummond, which saw its coal shipments frozen in early January for not complying with a new environmental law, may damage Colombia’s embattled mining industry even further.

The firm, Colombia’s second-largest coal producer, didn’t meet the government’s deadline for coal miners to build direct ship-loading facilities in their ports by January 1 this year.

“Whilst Drummond clearly overestimated its position as a big contributor for the Colombian arks, the decision to put a stop to the operations is an economical harakiri and demands a careful analysis,” said OPHIR Mining, Resources & Investment earlier this month.

The experts think Drummond negligence could have been managed through sanctions that didn’t harm the economic chain, as has happened with the interruption of all of Drummond’s shipments, which are equivalent to a third of the total coal production in Colombia.

Over 4,000 jobs could face temporary suspension, but the government has warned Drummond that it will not allow layoffs as the company has had seven years to complete the upgrading.

Introducing the Alpha Minerals spinco—Alpha Exploration Inc

With court blessing announced December 2 for the Alpha Minerals TSXV:AMW takeover by Fission Uranium TSXV:FCU, the deal faces just one more approval, this one from the TSXV. That was expected, but not announced, on December 6. Alpha’s spinco, Alpha Exploration Inc (anticipated ticker TSXV:AEX) gets about $3 million cash and all non-Patterson Lake South assets, including properties in Ontario and British Columbia as well as Saskatchewan. Each Alpha Minerals share fetches 5.725 Fission shares and one-half spinco share. Since December 3 Alpha Minerals shares have no longer traded with spinco shares attached.

The current Alpha Minerals board and management will “substantially” move into AEX positions.

Court approval for Fission Uranium’s spinco—tentatively titled Fission 3.0 to also commemorate Fission Uranium’s predecessor and Denison Mines’ TSX:DML acquisition Fission Energy—was announced the previous week. Each Fission Uranium shareholder gets one share of post-arrangement Fission Uranium as well as a share of the Fission spinout, expected to start trading December 10.

Having obtained full PLS ownership from its 50/50 joint venture ally, Fission Uranium has undoubtedly caught the attention of much bigger takeout artists.

Lakeland/Declan Resources JV accelerates work, strengthens their positions

In this market you have to work with strong partners. You have to collaborate and be a bit creative. We’re fortunate to work with people like Declan president Wayne Tisdale’s team and the financial connections they can bring.—Ryan Fletcher, director of Lakeland Resources

A new team of Lakeland Resources TSXV:LK and Declan Resources TSXV:LAN means an accelerated winter drill program for their Gibbon’s Creek flagship as well as the opportunity to put additional work into other Basin-area projects.

Declan’s first-year commitment will inject another $1.25 million into Gibbon’s, a 12,771-hectare north-central Basin property that already underwent over $3 million of work prior to last fall’s field campaign by Lakeland. Declan may earn 50% of the project by spending that $1.25 million, paying Lakeland $100,000 and issuing two million shares in 12 months. Over four years Declan may obtain a 70% interest for a total of $1.5 million in cash, 11 million shares and $6.5 million in spending.

The agreement further demonstrates Declan’s new direction, following its acquisitions in September and October of the 9,000-hectare Patterson Lake Northeast and 50,000-hectare Firebag River properties.

Declan’s commitment also allows Lakeland to ramp up its campaign for two other north-central Basin properties, South Pine and Perch Lake. Work on all those properties will be managed by Dahrouge Geological Consulting, led by PLS and Waterbury Lake veteran Jody Dahrouge.

Field results from Lakeland’s fall campaign are pending, while new appointments are anticipated from Declan.

Macusani claims low-cost uranium potential in Peruvian PEA

Macusani Yellowcake TSXV:YEL presented its case for a low-grade but potentially low-cost uranium mining operation in Peru with a preliminary economic assessment released December 5. The company envisions both open pit and underground operations with “a low stripping ratio in the open pit operations, anticipated low acid consumption and high process plant recoveries expected to be achieved in a short period of time.”

Uranium news from Saskatchewan and elsewhere for November 30 to December 6, 2013

The under-explored Macusani plateau shows considerable
uranium potential, according to the eponymous Macusani Yellowcake.

The report, using U.S. dollars, uses an 8% discount rate to calculate a $417-million after-tax net present value with a 32.4% internal rate of return. Those numbers assume a long-term price of $65 a pound uranium oxide (U3O8).

Initial capital expenditures would come to $331 million to build the mine and a plant processing 8.5 million tonnes per year. Total sustaining capital costs for the 10-year lifespan would reach $228 million. Payback would take 3.5 years.

Life of mine cash costs would average $20.57 a pound but, Macusani emphasized, years one to five would average $19.45, “placing it in the lowest quartile in the world using 2012 production figures.” Those first five years would produce an average 5.17 million pounds annually which would, were it operating now, rank the mine the world’s sixth largest, the company maintained. The 10-year average would be 4.3 million pounds.

The project, on the Macusani plateau in southeastern Peru, features multiple deposits, some adjacent to each other, others a few to several kilometres apart. The December 5 news release once again claimed last August’s resource update showed a 167% increase in measured and indicated categories. But there was no increase in the measured category. In fact measured pounds equal less than 1% of the M&I total.

Calling the project potentially “one of the lowest-cost uranium producers in the world,” Macusani CEO Laurence Stefan added, “The PEA demonstrates that the Macusani plateau has significant potential to become a major uranium-producing district, considering that only small areas have been explored to date.”

The company expects to begin pre-feasibility work in 2014.

NexGen announces initial geophysical results for Rook 1

An airborne radiometric survey over the PLS-vicinity Rook 1 project found at least five zones with elevated readings, NexGen Energy TSXV:NXE reported on December 2. Two of the zones are “proximal” to last summer’s drilling and could provide targets for another program beginning in January. Additionally aeromagnetic data identified regional and local basement structures.

The company will pursue the source of the elevated radiometrics next summer through ground radiometric surveying, mapping and sampling. Meanwhile the current data from 5,772 line-kilometres of high-resolution magnetic, very low frequency and radiometric surveys undergoes more comprehensive analysis.

Still to come are assays from NexGen’s nine-hole, 3,473-metre campaign at the eastside Basin Radio project, where the company holds a 70% option two kilometres east of Rio Tinto’s NYE:RIO Roughrider deposits. Having raised $5 million in late August, NexGen stated it’s still well-financed.

More near-surface, district-wide potential found in Argentina, says U3O8

In mid-November U3O8 Corp TSX:UWE said a discovery roughly 40 kilometres northeast of its Laguna Salada deposit could indicate district-scale potential. On December 4 the company stated another Argentinian discovery, on the southern extension of Laguna Salada, further suggests that potential. In both cases vertical channel sampling found near-surface, soft gravel uranium-vanadium mineralization.

Laguna Salada trials showed that screening could concentrate over 90% of its uranium in about 10% of the gravel’s original mass, resulting in 10 to 11 times greater grade, U3O8 stated. The company maintains its deposits offer continuous surface mining potential with alkaline leaching.

Dubbed La Susana, the new discovery’s slated for pitting and trenching to determine the extent of mineralization. While Laguna Salada’s PEA nears completion, the company continues JV negotiations with a province-owned mining company that could unite Laguna Salada with adjoining concessions.

U3O8 has a Colombian uranium-polymetallic project with a PEA and an earlier-stage project in Guyana.

Aldrin finishes Triple M gravity survey, offers $2-million private placement

With its ground gravity survey complete, Aldrin Resource TSXV:ALN stated anomalies coincide with previous results and already-identified drill targets. Data from 871 stations on Triple M, adjacent to and southwest of PLS, covered two parallel bedrock conductors already noted from an airborne VTEM survey and surface radon anomalies, the company reported on December 4.

Gravity anomalies consist of relatively low readings “reflecting the dissolution and removal of rock mass by the same basinal fluids that may also precipitate uranium,” Aldrin explained.

Two days earlier the company announced a $2-million private placement for Triple M exploration and drilling. The offer comprises 18.18 million units at $0.11, with each unit consisting of one flow-though share and one-half warrant, with each full warrant exercisable at $0.16 for 18 months.

In early November Aldrin reported closing a $972,500 first tranche of a private placement that had been announced the previous month. The company has also indicated plans to buy the Virgin property around the Basin’s south-central rim.

New Argentinian discovery might hold district-wide potential, says U3O8 Corp

Roughly 40 kilometres northeast of its Laguna Salada deposit in Argentina, U3O8 Corp TSX:UWE said it’s discovered a new area with the district’s “highest uranium-vanadium grades found to date.” La Rosada shows district-scale potential for Laguna Salada-style mineralization in near-surface, soft gravels, the company stated on November 12. But in addition, chip samples from adjacent basement rock show grades ranging from 0.01% to over 0.79% uranium oxide (U3O8). That might indicate a source of the gravel’s mineralization.

The extremely shallow, fine-sand mineralization potentially offers low-cost extraction through continuous surface mining, the company maintained. Screening tests at Laguna Salada, moreover, concentrated over 90% of the uranium in about 10% of the gravel’s original mass.

Vertical channel samples starting less than a metre from surface show a weighted average of 0.15% U3O8 and 0.08% vanadium pentoxide (V2O5). Some highlights show:

  • 0.12% U3O8 and 0.06% V2O5 over 0.7 metres

  • 0.13% U3O8 and 0.05% V2O5 over 0.5 metres

  • 0.25% U3O8 and 0.09% V2O5 over 0.9 metres

  • 1.18% U3O8 and 0.52% V2O5 over 0.4 metres

  • 0.24% U3O8 and 0.08% V2O5 over 1.5 metres

Highlights from horizontal channel sampling of the basement rock show:

  • 0.09% U3O8 and 0.04% V2O5 over 0.6 metres

  • 0.09% U3O8 and 0.04% V2O5 over 0.9 metres

  • 0.16% U3O8 and 0.07% V2O5 over 0.2 metres

  • 0.79% U3O8 and 0.26% V2O5 over 0.1 metre

  • 0.17% U3O8 and 0.06% V2O5 over 0.4 metres

The company didn’t provide the depth to basement.

Further near-surface exploration is planned south of the discovery while the basement calls for systematic trenching to determine its “potential as a target in its own right,” U3O8 stated. Planned for year-end completion is Laguna Salada’s preliminary economic assessment and a hoped-for joint venture with a state-owned company holding adjacent claims.

Laguna Salada has a 2011 resource estimate showing:

  • an indicated category of 47.3 million tonnes averaging 0.006% U3O8 and 0.055% V2O5 for 6.3 million pounds U3O8 and 57.1 million pounds V2O5

  • an inferred category of 20.8 million tonnes averaging 0.0085% U3O8 and 0.059% V2O5 for 3.8 million pounds U3O8 and 26.9 million pounds V2O5

Elsewhere U3O8 has completed a PEA for its Berlin uranium-polymetallic project in Colombia and holds two earlier-stage projects in Argentina and Guyana.

Fission/Alpha release results from two PLS zones, lengthen strike by 15 metres

Releasing both scintillometer readings and assays the same week, Alpha Minerals TSXV:AMW and Fission Uranium TSXV:FCU provided a prompt update from their current Patterson Lake South drilling as well as results from last summer’s campaign. On November 12 the 50/50 joint venture partners said they’ve confirmed the sixth zone announced last week, extending it 15 metres east and 10 metres north. Two days later they reported five more holes bearing high grades from R390E, the third most-easterly zone along what’s now a 1.8-kilometre trend.

Starting with the newly discovered R600W zone, the partners reported readings from a handheld device that measures gamma ray particles from core in counts per second, maxing out at an off-scale reading above 9,999 cps. Scintillometer results are no substitute for assays, which are pending.

Both holes were sunk at -89 degrees, making downhole depths close to vertical. Hole PLS13-121 reached a total depth of 248 metres, encountering just a bit of sandstone at 98.7 metres before hitting the basement unconformity at 99 metres. Some of the better results show:

  • <300 cps to >9,999 cps over 11.3 metres, starting at 98.7 metres in downhole depth

  • <300 cps to 600 cps over 3.5 metres, starting at 141 metres

Hole PLS13-122 totalled 332 metres in depth, reaching the basement unconformity at 100 metres without finding sandstone. Some highlights show:

  • <300 cps to 800 cps over 2 metres, starting at 101.5 metres in downhole depth

  • <300 cps to 510 cps over 4 metres, starting at 106 metres

  • 430 cps to 1,900 cps over 1 metre, starting at 158.5 metres

True widths weren’t provided.

Turning to zone R390E and real lab assays, some highlights show:

Hole PLS13-078

  • 0.66% U3O8 over 30 metres, starting at 85 metres in downhole depth

  • (including 7.62% over 1.5 metres)

  • 0.12% over 7.5 metres, starting at 128 metres

Hole PLS13-081

  • 0.19% over 18.5 metres, starting at 106 metres

  • Hole PLS13-085

  • 0.93% over 22 metres, starting at 82.5 metres

  • (including 4.07% over 4 metres)

Hole PLS13-086

  • 1.93% over 43 metres, starting at 81.5 metres

  • (including 9.91% over 5 metres)

Hole PLS13-087A

  • 0.28% over 4 metres, starting at 45.5 metres

  • 0.4% over 8.5 metres, starting at 63.5 metres

  • 0.12% over 16.5 metres, starting at 92.5 metres

True widths weren’t available. Dips strayed no more than six degrees from vertical.

With $2.25 million funding an 11-hole, 3,700-metre extension to the summer/fall campaign, land-based work now focuses on the R600W area while waiting for the lake to freeze. Meanwhile more assays are expected from the previous barge-based drilling to the east.

Alpha acquisition vote looms; Fission and Dahrouge square off in legal battle

November 28’s the day when Fission and Alpha shareholders vote on the latter’s acquisition by the former. Mentioned in the companies’ joint November 15 update was a barely publicized legal dispute between Fission and Dahrouge Geological Consulting, its principals and a related company.

Seeking unspecified damages, Fission filed a notice of civil claim on July 29 alleging “breach of fiduciary duties and knowing assistance in breach of the same.” On November 8 the defendants filed a counter-claim with “allegations of breaches of British Columbia securities laws, slander, wrongful interference, improper assignment and improper variation of obligations. The relief being sought in the counter-claim includes unspecified losses and damages, declarations of ownership in relation to certain mineral permits and claims, declarations concerning the enforceability of certain assignments, injunctions preventing the defendants by way of counter-claim from disparaging certain mineral permits and claims, interest and costs.”

The account of the defendants’ counter-claim comes from a draft version reported in Fission and Alpha circulars dated October 30. Neither claim has been tested in court.

International Enexco/Cameco/AREVA plan winter drilling at Mann Lake

A three-way JV intends to start the new year with a $2.9-million drill program for the eastside Athabasca Basin Mann Lake project. Up to 18 holes will evaluate three types of targets—the area footwall to the western axis of the C trend, remaining targets along the main C trend and conductive features near the western margin of the Wollaston sedimentary corridor, International Enexco TSXV:IEC stated on November 13. The company holds a 30% interest in the 3,407-hectare property, along with AREVA Resources Canada (17.5%) and Cameco Corp TSX:CCO (52.5%).

This year’s drilling totalled 21 holes for 15,721 metres, focusing on the C conductor, which Enexco describes as a six-kilometre-long section of a regional trend extending from Cameco’s McArthur River mine to Denison Mines’ TSX:DML Wheeler River deposit.

The previous week Enexco reported three holes from the southeastern Basin’s Bachman Lake, a 20/80 JV with Denison, which holds a 7.4% interest in Enexco. The latter also keeps busy with pre-feasibility work at its 100%-held Contact copper project in Nevada.

Aldrin reports radon results from Triple M

With its Triple M property’s surface radon survey complete, Aldrin Resource TSXV:ALN announced some results from 527 sample sites on November 14. The findings show elevated values over more than one kilometre of a VTEM bedrock conductor, which the company interprets as a steeply south-dipping fault zone. “The most intense portion of this radon anomaly reaches a high value of 1.68 pCi/m²/s [picocuries per square metre per second] and extends for more than 200 metres, comprising a priority drill target,” Aldrin stated.

The company added that the fault zone parallels the conductor hosting the PLS discovery on the Alpha/Fission project adjacent to and northeast of Triple M. North of the fault zone, and parallel to it, sits a second VTEM basement conductor with radon values up to 1.18 pCi/m²/s.

The previous week Aldrin reported closing a $972,500 first tranche of a private placement that had been increased to $1.5 million. The company has also previously announced an agreement to buy the 49,275-hectare Virgin property around the Basin’s south-central edge.

Shares in Batero Gold TSXV:BAT jumped as much as 8% in volumes 10 times higher than usual on November 8 after releasing a PEA for its Colombian project earlier this week.

In early afternoon trade the Vancouver-based explorer fell back slightly from highs earlier in the day to trade at $0.125, up 4.2% with more than 615,000 shares changing hands, including one 250,000-block at $0.13.

That compares to usual volumes below 50,000 and made Batero the tenth-most traded stock on the Venture exchange.

It has been a busy week for Batero, kicking off on November 4 with the company announcing a preliminary economic assessment of its 100%-owned Batero-Quinchia project in Riseralda, Colombia, board changes and new prices for warrants issued two years ago.

What makes Batero-Quinchia a particularly attractive asset according to the PEA is the “relatively high gold recoveries and fast leach kinetics of the surface oxide mineralization within the Batero-Quinchia deposit.”

Highlights of the PEA, with a base case gold price of $1,400 an ounce, include:

  • Mine life of seven years at 3.5 million tonnes per annum production steady state (10,000 tonnes per day)

  • Life-of-mine (LoM) production of 390,000 ounces of gold and 817,000 ounces of silver recovered

  • Annual average production of 56,000 ounces of gold and 117,000 ounces of silver recovered

Total open pit production, which has been factored for mining extraction and mining dilution:

  • 9.4 million tonnes of measured mineral resources at 0.81 grams per tonne gold and 1.8 g/t silver for 244,000 ounces of contained gold and 545,000 ounces of contained silver

  • 11 Mt of indicated mineral resources at 0.77 g/t gold and 2 g/t silver for 273,000 ounces of contained gold and 720,000 ounces of contained silver

  • 3.3 Mt of inferred mineral resources at 0.59 g/t gold and 1.6 g/t silver for 64,000 ounces of contained gold and 171,000 ounces of contained silver

  • Approximately 86% of open pit production tonnage is classified as measured or indicated mineral resources

  • Mining strip ratio of 0.3:1 (waste:production)

  • LoM average gold and silver heap leach recoveries of 67% and 57% respectively

  • Initial capital cost of $97.3 million, which includes $16.2 million in contingency costs

  • Pre-tax payback of 23 months

  • Net pre-tax cashflow of $105 million

  • Pre-tax internal rate of return (IRR) of 27%

  • Pre-tax net present value (NPV) at a 5% discount rate of $69.1 million

  • Total cash operating cost (net of silver credits) of $842 per ounce gold

  • After-tax payback of 30 months

  • Net after-tax cashflow of $76.9 million

  • After-tax IRR of 21%

  • After-tax NPV at a 5% discount rate of $47.3 million

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.

Uranium news from Saskatchewan and elsewhere for September 21 to 27, 2013

Patterson Lake South now has a fifth zone—or a
potential fifth zone, depending on whom you listen to.

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

Uranium news from Saskatchewan and elsewhere for September 21 to 27, 2013

Brecciated core from NexGen Energy’s Rook 1 drill program.

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.
