Bayfield Drills13.0 g/t Au and 70.22 g/t Ag over 6.6m within 39.95m of2.51 g/t Au and 20.47 g/t Ag in Rainy River, NW Ontario

Bayfield Ventures Corp. (TSX-V: BYV) (FWB: B4N) (the "Company")is pleased to announce additional significant gold intercepts on its 100%ownedBurns Block property in the Rainy River District of north-western Ontario.

The Burns Block is situated adjacent to the east and on strike to RainyRiverResources' (TSX-V: RR) multi-million ounce gold deposit. Rainy RiverResources'February 2011 NI 43-101 resource calculation shows a low grade, bulktonnagedrill indicated resource of 3.42 million ounces of gold, averaging 1.1grams pertonne gold, in addition to an inferred resource of 3.17 million ounces ofgold,averaging 0.91 grams per tonne gold. Of the total 6.59 million ounces ofgoldinferred and indicated, 5.91 million ounces of gold are contained withinopenpit parameters and the remaining 0.68 million ounces of gold are belowopen pitdepths.

Highlights:* Notable high grade gold intercept: 13 g/t gold over 6.6 metres, within39.95 metres of 2.51 g/t gold in drill hole RR11-5.* The gold zone in RR11-5 represents the up-plunge extension of the highgrademineralization intercepted in previous holes RR10-15, RR10-18, RR10-52andRR11-1.* Significant silver mineralization accompanying gold mineralization inRR11-5 including 70.22 g/t silver over 6.6 metres within 39.95 metres of20.47g/t silver.* East step out hole RR11-2, located 140 metres east of the west Burnsboundary, intersects 4.1 metres of 1.85 g/t gold and 2 metres of 2.44g/tgold within 29.5 metres of 0.60 g/t gold. Silver assays are pending.* Gold intercepts reported on Bayfield's Burns Block continue to defineeastern extension of Rainy River Resource's main ODM17 gold zone.* Infill and up-plunge extension drilling on the high grade zonecontinueswith one rig* Expansion drilling of the continuation of the ODM17 zone to the east ontheBurns Block continues with second rig.* Assays pending for ten more holes.

Discussion of Results from Hole RR11-5:

Hole RR11-5 was collared 25 metres north of previously announced high gradegoldintercept in hole RR10-15. Hole RR11-5 was drilled by Bayfield earlyin our2011 exploration program as part of an effort to extend the known strikelengthof high grade gold and silver mineralization intersected in July andAugust,2010 in the western portion of the Burns block land position. Local, cm-scaleintervals containing visible gold were noted during logging of themineralizedinterval in RR11-5. Coarse gold and electrum occur as both isolated blebsand incross cutting fracture fillings within a distinctive foliated andsericitealtered dacite host rock. Accessory minerals include abundant darkbrownsphalerite, blebs of chalcopyrite and arsenopyrite as well as deformedpyritestringer veins and cross cutting galena veinlets.

Significant assay results from RR11-5 are summarized in the tablebelow.Significant silver mineralization occurs with the gold mineralization.Silvercontent of the mineralization has an important impact on the gradeof themineralized zones when combined and expressed as gold equivalent values orAuEq(far right column of the table).

Discussion of Results from Hole RR11-2:

Hole RR11-2 was collared 50 metres east of hole RR10-53, a position 150metreseast of the southwest corner of the Burns Block. The holeintersected thetargeted foliation, strong sericite alteration and sulfide mineralizationzonefrom 275 metres to 390 metres downhole. The 29.5 metre thick interval ofgoldmineralization was found within the altered zone. Assays, shown in thetablebelow, include 9.2 metres of 1.05 g/t gold and 2 metres of 2.44 g/t goldwithin29.5 metres of 0.60 g/t gold. Silver assay are pending.

The mineralization intersected in RR11-2 is very encouraging as it clearlyshowsthat the gold system extending east from the ODM-17 Zone of RaineyRiverResources is maintaining a respectable thickness and grade ofgoldmineralization at a point 150 metres east of the Company's west boundary.Theseresults are another significant step for Bayfield in the definitionof thesignificant tonnage of mineralized dacite within 300 metres from surface.

Current Exploration Summary:

Bayfield is still at an early stage of exploration on its Rainy Riverpropertieswith approximately 28,000 metres of drilling completed out of theplanned50,000+ metre drill program. The program is focused on twocomplimentaryexploration efforts, extension of the high grade zone in the west portionof theblock and eastward exploration towards the central portion of the block.Assaysare pending for ten additional completed holes (RR11-6 through RR11-15).

Expansion drilling of the high grade zone discovered by Bayfield lastAugustcontinues to show excellent results, as demonstrated by the results ofthe up-plunge extension hole RR11-5 reported here. The significantthickness ofpotential open pit grade (21.2 metres of 4.37 g/t gold and 28.20 g/tsilver) inRR11-5 occurs at a vertical depth of only 140 metres. The results fromRR11-5fit well with our goal of delineating a significant resource of an averagegradesimilar to that announced by Rainey River resources.

Bayfield is continuing to explore the up-plunge extension of the high gradezonetoward the north. In the near future, a series of infill holes will bedrilledalong the north exploration fence. The results of that work will beused toplan a more northerly fence to continue to chase the high grade zone uptowardssurface.

A second rig is continuing to expand the known mineralization eastwardand iscurrently drilling 190 metres east of the Company's west boundary (aposition40 metres east of hole RR11-2).

Quality Assurance:

Drill core analysis and assaying is being conducted by ACT Labs in ThunderBay,Ont. The lab is ISO/IEC 17025:2005 (CAN-P-4E) certified. The drill core issplitand sampled in standard 0.5 metre to 1 metre intervals. The core sampleswereanalyzed for gold by 30-gm fire assay with AA finish and by gravimetricmethodsfrom assays over 3000 ppb (over limit). Screened total metallic assays arebeingperformed on samples assaying over 10,000 ppb. The Company hasimplemented aquality assurance and quality control program to ensure that thesampling andanalysis of all samples is conducted in accordance with the bestpossiblepractices.
