The initial stage of drilling commenced on Bayswater’s 100% owned Anna Lake Property during July of 2007. The drilling targeted a portion of a 12 kilometre structural corridor that was the focus of Bayswater’s early stage exploration program and where uraniferous boulder trains were previously identified. Geochemical analysis from the first hole drilled, AL07-01, returned assays grading 0.07% U3O8 over 40 metres. Subsequent drilling has successfully delineated the Anna Lake Uranium Deposit over a 750 metre strike length and to a depth of 663 metres in the plane of the mineralization. To date, 25,355 metres of core have been recovered from 74 holes at Anna Lake. In October 2009, Bayswater announced the results of an independent NI 43-101 mineral resource estimate by R. Dean Fraser and Gar H.Ginoux of September 2009 filed on Sedar which indicates an Inferred resource of 4.91 million pounds U3O8 in 5.06 million tons grading 0.044% U3O8 using a 0.03% U3O8 cutoff.

Location & History

The Central Mineral Belt Uranium District (CMB) of Labrador extends for more than 250 km through the south-central portion of Labrador. The CMB is host to numerous significant uranium deposits and abundant prospects and showings, making it one of the most important uranium exploration districts in Canada. Bayswater currently holds the largest land position in the district with 100% interest in 504,157 acres of highly prospective ground. The Company also holds a 50% interest in 28,664 acres of joint venture land with UCore Uranium. The Anna Lake Deposit and favourable structural corridor are located within a group of 512 claims covering a 31,630 acre area. See the Central Mineral Belt Profile for detailed descriptions of location, history, geology and exploration on the CMB Project.

The Anna Lake Deposit is located within the CMB approximately 150 kilometres north-northeast of Happy Valley-Goose Bay and 35 kilometres southwest of the coastal community of Postville. All exploration programs undertaken to date have been based from the town of Postville. With a population of approximately 250 people, the community provides excellent infrastructure along with a small, able work force, whose members have experience in exploration through the various junior companies active in the area, including Voisey's Bay Nickel. Access to Postville can be obtained by regularly scheduled commercial twin otter aircraft, or the less frequent coastal ferry service from the main center of Goose Bay. Road access is not available in or out of the community. Access to the immediate deposit area is only possible by helicopter, although float planes can land on nearby lakes. The Anna Lake Deposit is located 15 kilometres northwest from Fronteer Development’s Michelin deposit which hosts a resource of over 100 million lbs of U3O8. A proposed development road leading to the community of Postville from the Michelin deposit will come within 13 kilometres of the Anna Lake Deposit.

The Anna Lake Deposit is located within lands governed under the Labrador Inuit Settlement Area (LISA) Agreement which are administered jointly by the Newfoundland and Labrador and Nunatsiavut Governments. Both Governments welcome exploration and development of resources in these areas. The mineralized zone lies completely outside of Labrador Inuit Lands (LIL) which is currently the subject of a three year temporary moratorium on uranium mining. A decision on the moratorium is expected during the spring of 2011.

The discovery of high grade radioactive boulders in the Melody Hill area in 1965 by Mokta (Canada) Ltee., led to periodic exploration in the Anna Lake-Melody Hill area during 1970-1971, 1974-1975, 1977 and in more detail by Brinco/Brinex from 1978 to 1981. Melody Hill is located approximately nine kilometres east of Anna Lake. Reconnaissance mapping and prospecting carried out near Melody Hill during the summers of 1979 and 1980, resulted in the discovery of 2,146 radioactive boulders in six fans, approximately 2.8 km north of Anna Lake. Designated as the Anna Lake North prospect, Brinex followed up in 1981 with detailed ground work over the Anna Lake boulder train including gridding, limited stream and silt geochemistry, a radon cup survey, mag/VLF geophysics, a ground scintillometer survey and sampling of boulders in the area. Following the ground work, a series of 11 short diamond drill holes totaling 1,222 metres was completed. Results from the drilling program proved interesting with four of the holes encountering uranium mineralization. The best intersection assayed 0.180% U3O8 over 1.5 metres. Numerous boulders returned assays greater than 1% U3O8, with the best sample returning a grade of 2.4% U3O8, and a calculated average for all mineralized boulders of 0.15% U3O8. Two other boulder trains in the area were not tested and results suggested there was good potential in the area for additional mineralization to be discovered. Due to deteriorating uranium market conditions, exploration was curtailed during the 1980’s. No further work was conducted until 2006 when Bayswater acquired the ground as part of a much larger land package in the CMB. During 2006, an extensive high resolution airborne survey was flown over its entire land package and ground follow-up work was carried out. A detailed examination of all available historic data revealed that the Brinex drilling was performed in a less than ideal orientation to intersect what Bayswater interpreted as a north-south trending mineralized zone. Subsequent drill testing in 2007 by Bayswater confirmed this interpretation and led to the discovery of the Anna Lake Deposit.

Geology & Mineralization

The Central Mineral Belt Uranium District (CMB) is hosted within, and is spatially related to the structural intersection of the Nain, Makkovik and Churchill structural provinces and the Grenville Province Over-Thrust Belt to the south. Collectively, these provinces are composed of Archean to Mesoproterozoic gneissic, sedimentary, volcanic and granitic rocks. The rocks of the Makkovik Province and metamorphosed equivalents south of the Grenville front host most of the Central Mineral Belt uranium mineralization discovered to date. Bedrock within the Makkovik Province consists of reworked Archean Hopedale Block gneisses, granodioritic to granitic intrusive bodies, mafic to felsic volcanic and volcaniclastic rocks, and metamorphic schistose equivalents varying in age from Archean to Paleoproterozoic. The Anna Lake Deposit is situated within the Post Hill Group of the Makkovik structural province which consists primarily of variably metamorphosed surpracrustal rocks.

A portion of the Anna Lake Property containing the Anna Lake Uranium Deposit was grid mapped as part of the Company’s 2008 field program. Over 75% of the area is covered by glacial detritus, consisting mainly of fans, trains, sheets and drumlinized piles of blocks and boulders. Bedrock within the Anna Lake area has been subjected to a long and varied tectonic and metamorphic history. These rocks have most likely undergone four major orogenic events including the Hudsonian, Makkovikian, Labradorian and Grenvillian. The rocks exhibit evidence of at least one exposure to upper amphibolite metamorphism, and in drill core of partial melting. Complex fold patterns, shearing, mylonitization, faulting, and disruption of rock units can also be observed in outcrop and in drill core. A detailed geological map of the grid area showing basic tectonostratigraphic divisions of rock units underlying the grid area has been provided below.

Bedrock underlying the Anna Lake grid area consists of a variably metamorphosed and tectonically dismembered belt of supracrustal and intrusive igneous rocks. These can be divided into five mappable units. They include supracrustal rocks of volcanic and sedimentary origins, granite/granodiorite, mafic dykes, magnetite bearing granites and amphibolites. Pegmatite dykes are also common throughout the area. The supracrustal rocks of the Post Hill Group host the Anna Lake Deposit along with numerous other deposits including the high grade Kitts Deposit which is located along strike to the northeast.

The Anna Lake Deposit occurs as a continuous north-south trending, 60 to 70 degree easterly dipping and broadly undulating sheet like body. Uranium mineralization is predominantly hosted within and spatially related to grey-red-brown, crenulated garnetiferous biotite schist unit. These rocks, along with a thick sequence of supracrustals, form the hanging wall to a quartz sericite altered mylonite zone. The altered mylonite grades into a coarse grained k-spar granitic intrusive and defines the boundary between the hanging wall and footwall rocks. The contact zone is currently thought to represent a pre-existing structural zone of weakness that may have controlled alteration and mineralization. Pegmatites locally cut the mineralized zone and are common in the hanging wall unit. Wide spaced drilling has currently delineated the Anna Lake Deposit over a strike length of 750 metres and down-dip in the plane of the mineralization to 663 metres. The deposit remains open along strike to the north, south and at depth. A longitudinal section of grade x thickness has been provided below. Two higher grade lobes are identified within the deposit. Significant assays for all drilling to date can be found in press releases dated October 29, 2007, December 10, 2007, August 06, 2008 and February 17, 2009.

To date, 25,355 metres of core had been recovered from 74 drill holes on the Anna Lake Uranium Deposit. In a release dated October 15, 2009, Bayswater announced the results of an independent NI 43-101 Mineral Resource Estimate for Anna Lake performed by Mr. Gary Giroux (P.Eng.) of Giroux Consultants Limited and R. Dean Fraser (P.Geo.). The estimate indicates an Inferred resource of 4.91 million pounds of uranium oxide using a 0.03% U3O8 cutoff (5.06 million tonnes averaging 0.044% U3O8). Also contained within this resource are an estimated 1.56 million pounds of molybdenum and 1.00 million grams of rhenium.

Exploration

Extensive detailed exploration work by Bayswater was undertaken on the Anna Lake Property during 2006, 2007 and 2008. A multi-disciplined approach was implemented over the Anna Lake area in an attempt to identify and delineate uranium mineralization. Work performed to date includes high resolution airborne magnetic, radiometric and electromagnetic surveys, 180 kilometres of grid establishment, geological grid mapping, 146 line kilometres of ground magnetometer survey, 109 line kilometres of induced polarization surveying, 6400 conventional soil geochemical samples, radon flux surveys constituting 2,716 measurements and 25,335 metres of diamond drilling. The following lists the sequence of all work performed on the Anna Lake Project:

2006

• A detailed compilation of all government archived data was completed prior to the initial field program.
• Fugro Airborne Surveys was contracted to fly a high resolution radiometric/magnetic survey over the entire land package. A total of 41,561 line kilometres of data was collected. Fight lines in the Anna Lake area were flown at 100 metre line spacings.
• A first pass prospecting and sampling program in the Anna Lake area confirmed the presence of significant uranium mineralization within the Anna Lake boulder field.

2007

• AeroQuest International was commissioned to fly an EM survey over a selected portion of the Bayswater claims. A total of 5,878 line kilometres of data was collected. The Anna Lake area was flown at 100 metre line spacings.
• The establishment of a cut grid was initiated over the Anna Lake zone for ground control.
• Ground geophysical surveying including the induced polarization and ground magnetometer methods, along with conventional soil geochemistry and radon flux surveys commenced.
• A preliminary diamond drill program was implemented on the Anna Lake target to test for uranium mineralization. A total of 9,668 metres in 41 holes was drilled as a result of encouraging results in the Phase 1 Bayswater drill program.
• The discovery and near surface delineation of the Anna Lake Deposit was verified by diamond drilling.
• Additional prospecting and sampling of the area was performed by Bayswater field crews.

2008

• A Phase 2 diamond drill program was initiated to expand the Anna Lake Deposit. A total of 15,687 metres of drilling was completed in 33 holes on the deposit and on targets in the immediate area.
• Continued gridding, ground geophysics, ground geochemistry and radon flux surveys were completed by Bayswater field personnel along the Anna Lake corridor.
• A geological mapping program of the grid area was completed.
• Additional prospecting was performed on the Anna Lake claims.

2009

• An independent NI 43-101 mineral resource estimate indicated an Inferred resource of 4.91 million pounds of uranium oxide using a 0.03% U3O8 cutoff.

Results from work performed in the Anna Lake area have successfully outlined the Anna Lake Uranium Deposit. Additional delineation and infill drilling is required to fully define the extent of the deposit. The Anna Lake Deposit currently remains open along strike to the north, south and at depth. Numerous high priority targets proximal to the deposit have also been identified and will require reconnaissance drill testing.
