Toronto Stock Exchange (TSX): CVV

VANCOUVER , June 19, 2012 /CNW/ - CanAlaska Uranium Ltd. (TSX - CVV) ("CanAlaska" or the "Company") is pleased to announce assay and trace element geochemistry results for the Grid 5 winter drilling program at its West McArthur project, a 50/50 joint venture between the Company and MC Resources Canada Ltd., a subsidiary of Japan's Mitsubishi Corporation (See also News Release - April 13 th, 2012). The seven drill holes completed during the program, comprising total drilling of 6,421.5 metres, tested targets along six kilometres of conductive trends located immediately SW of the new uranium discovery at Read Lake (See Cameco's website description of its Read Lake project and Saskatchewan Geological Assessment Report #74H-0065).

Drill holes WMA028 and WMA034 produced very positive results for uranium. Both intersected parts of a highly-altered graphitic pelite unit and are thought to be within 50 metres of the targeted conductor, which was identified from the down-hole geophysical surveys.

The targets generated at the eastern end of Grid 5 matched and extended a historical conductor, which was drill-tested by Uranerz in 1989. Neither of the two historical drill holes intersected their targeted basement conductor, but, significantly, contained dravite clay and pyrite along with narrow, steep, clay rich fault gouges/breccia in the top 350-400 metres of the sandstone column. In one historical hole, the upper 400 metres of sandstone showed anomalous uranium and trace elements. Drill holes WMA028 and WMA034 are located in this area. Both show deep alteration into the basement rocks, indicating and confirming a substantial hydrothermal alteration system.

Drill hole WMA028 intersected a series of fracture zones and faults between 80 metres and 335 metres above the unconformity, and a geochemical halo (U, As, Ni)reaching 23 metres above the unconformity In drill hole WMA034, the geochemical halo extended 360 metres above the unconformity (U, B, As, Ni, Cu in the first 125 metres, followed by As only for the next 235 metres). Below the unconformity, WMA028 and WMA034 intercepted multiple graphitic pelites and semi-pelites, with up to 35% disseminated graphite, as well as graphite-rich breccia zones with up to 60% graphite in the matrix. The borehole EM surveys indicate that neither of these holes intercepted the main conductor on which they were targeted.

Drill hole WMA028 (see Figure 2) shows a series of fracture zones and faults from 450 metres to 730 metres down-hole, associated with hydrothermal bleaching. The last 25 metres of sandstone are enriched in uranium, arsenic and nickel associated with Mg-chlorite and sudoite alteration. The basement rocks are clay altered. A radioactive peak of 1,220 cps (counts per second) in probing at 786.55 metres corresponds to one metre at 0.014 % U3O8, associated with anomalous nickel, arsenic, cobalt, copper, and gold values (see table). A radioactive peak of 1,165 cps occurs at 790.4 metres. This assayed 0.030 % U3O8 over 0.5 metres. The borehole EM survey indicates that any follow-up drilling should target the main graphitic unit which is imaged just to the south of the intersection.

Drill hole WMA034 (see Figure 3) has a strong geochemical halo combining uranium, nickel copper, and arsenic which reaches 360 metres above the unconformity. It also shows stronger hydrothermal alteration signature in the last 20 metres of sandstone, but less structural disturbance than drill hole WMA028. The strong geochemical halo at the base of the sandstone is associated with bleaching, disseminated and sooty pyrite and faulting.

The basement rocks in drill hole WMA034 contain graphitic pelites, but the borehole EM survey indicates the target is 50 metres north of the drill hole. A radioactive peak just below the unconformity corresponds to 0.5 metres at 0.013 % U3O8 in a six metre zone of metal enrichment (nickel, arsenic, cobalt, and copper) starting immediately below the unconformity. There is a 6-metre zone of graphitic breccia with multiple fracture events from 929.3 to 935.3 metres and clay (kaolinite) alteration to the bottom of the hole.

*EPA Honors 2012 Presidential Green Chemistry Challenge Award Winners*

WASHINGTON June 18, 2012: Today the U.S. Environmental Protection Agency recognized innovative chemical technologies that have the potential to prevent pollution in the United States. These awards recognize leading researchers and industrial innovators who create safer and more sustainable chemical designs, processes, and products that reduce the need to use chemicals that pollute the environment and threaten Americans' health. The awardees were honored during the 17th Annual Green Chemistry Challenge Awards Ceremony in Washington, D.C.

"EPA congratulates the 2012 winners for designing, developing, and implementing these innovative green chemistry technologies that will help create more sustainable industries and greener, safer products to protect people's health and the environment," said Jim Jones, EPA's acting assistant administrator for the Office of Chemical Safety and Pollution Prevention. "These are exciting technologies that have great potential to improve the safety of the detergents and personal care products we use in our homes; reduce energy consumption and hazardous waste in industrial metal production processes; improve the paper goods and plastics we use daily so that they are made with a smaller environmental footprint and can be recycled more effectively; and even a potential alternative to BPA-based can linings,"

The Presidential Green Chemistry Challenge Awards include five categories: Academic, Small Business, Greener Synthetic Pathways, Greener Reaction Conditions and Designing Greener Chemicals.

This year, EPA is recognizing two winning academic technologies: Robert M. Weymouth, PhD, Stanford University, Stanford, Calif., and James L. Hedrick, PhD, San Jose, Calif., for organic catalysis -- an innovation that removes hazardous metals used in the production of plastics. The technique creates a safer end product that allows bottle-to-bottle recycling, thereby providing an opportunity to reduce the millions of pounds of plastics that end up in landfills.

Geoffrey W. Coates, PhD, Cornell University, Ithaca, N.Y., for synthesizing biodegradable polymers from carbon dioxide and carbon monoxide that can be used in a wide range of adhesives, foams, plastic and potentially lead to the development of a BPA-alternative for use in can linings.

In the small-business category, Elevance Renewable Sciences, Inc., Woodridge, Ill., is being recognized for the production of high-performing, green specialty chemicals at advantageous costs. These green chemicals can be produced with less energy, significantly reduced greenhouse gas emissions compared to petrochemical technologies, and used in a wide range of consumer and industrial products and processes.

Winners in the "Greener Reaction Conditions, Designing Greener Chemicals, and Greener Synthetic Pathways," categories include:

Cytec Industries Inc., Woodland Park, N.J. for MAX HT "Bayer Process" scale inhibitor products that result in a drastically more energy efficient and less hazardous process for the production of alumina, a raw material for making aluminum. Application of this technology can result in reducing hazardous acid waste by millions of pounds annually and preventing billions of pounds of CO2 from being released into the atmosphere.

Buckman International, Inc., Memphis, Tenn., for enzymes to be used in papermaking that modify the cellulose in wood to increase the number of "fibrils" that bind the wood fibers to each other. The innovation produces paper with improved strength and quality without additional chemicals or energy. The process also allows papermaking with less wood fiber and higher percentages of recycled paper, enabling a single plant to save $1 million per year.

Andrew Garfield and Emma Stone

Emma Stone and Andrew Garfield had 'instant chemistry'.

The couple began dating after meeting on the set of 'The Amazing Spider-Man' and the actress loved working closely with the actor on the superhero movie and hoped their close bond is reflected in their characters.

Emma - who plays Gwen Stacy - said: 'It was really great to work with Andrew. We just had instant chemistry as soon as we were on set and I think it was great to be able to build that relationship.'

Emma has previously worked with hunky actors including Penn Badgley in 'Easy A' and Ryan Gosling in 'Crazy, Stupid, Love' and jokingly claimed she only agrees to appear in films with 'hot' co-stars.

Speaking at the UK premiere of 'The Amazing Spider-Man' in London's Leicester Square this evening (18.06.12), she told BANG Showbiz: 'I only seem to work with hot men and it''s pretty great to get that contractually written.'

The 23-year-old beauty also admitted she much prefers the 'romance' element to 'The Amazing Spider-Man' as she was more comfortable shooting those scenes than getting to grips with anything physical.

She said: 'The romance is my favourite part of filming because I don't do the action quite as well.'
