Bayfield Reports Silver Results from Further Assaying 2010 Drilling in Rainy River, NW Ontario

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 20, 2011) - Bayfield Ventures Corp. (TSX VENTURE:BYV) (FRANKFURT:B4N) (the "Company") is pleased to announce silver results from further assaying 2010 drilling on its 100% owned Burns Block property in the Rainy River District of north-western Ontario. The Burns Block is situated adjacent to the east and on strike to Rainy River Resources' multi-million ounce gold and silver deposit. Rainy River's February 2011 NI 43-101 resource calculation shows a drill indicated resource of 3.42 million ounces of gold, averaging 1.1 g/t gold, in addition to an inferred resource of 3.17 million ounces of gold, averaging 0.91 g/t gold. It also contains a drill indicated resource of 6.61 million ounces of silver, averaging 2.19 g/t silver, in addition to an inferred resource of 8.10 million ounces of silver, averaging 2.32 g/t silver.

Highlights:

--  Silver mineralization at the Burns property has an important impact on
    the total metal value of mineralized zones discovered by Bayfield to
    date 
--  Impact can be seen by comparing gold grade with gold equivalent grade 
--  Silver mineralization at Burns could be very important in eventual
    assessment of economic viability 
--  Hole RR10-10 returned 358 g/t silver over 3 metres which adds 10.52 g/t
    gold equivalent value 
--  Hole RR10-11 returned 303 g/t silver over 1 metre which adds 8.91 g/t
    gold equivalent value 
--  Previously reported hole RR10-18 returned 360 g/t silver over 10 metres
    which adds 10.58 g/t gold equivalent in addition to gold assays of 36
    g/t 
--  Silver assays for holes RR10-37 to RR10-54 are pending 

Completion of Silver Assays from 2010 Drilling at Burns Block:

The chart below summarizes another major batch of silver assays from the 2010 drilling at the Burns Block. These assays are from holes RR10-08 to RR10-36. The silver assays from holes RR10-37 to RR10-54 are pending and represent the last of the catch-up silver assays from last year. Bayfield is now running silver assays on all samples submitted for gold assay.

The coexistence of gold and silver at the Burns property has an important impact on the total metal value of the mineralized zones at the project. This impact can be seen by comparing the gold grade with the gold equivalent grade of the intervals in the table and by simply reviewing the listed silver assays.

The gold numbers in the chart have all been previously reported. Significant silver mineralization at the Burns Block occurs solely within zones of gold mineralization. This fact strongly suggests that the main stage gold mineralization event in the district was in fact a gold-silver event.

Silver mineralization occurs in at least two forms at the Burns Block. Based on detailed core logging observations, it is known that silver occurs both combined with gold as the alloy electrum and as native silver. It should be noted, however, that these determinations have been made based on the color of the visible veinlets, blebs and smears of native metals. It is likely that what we are identifying as native silver also contains at least some alloyed gold.

The majority of high grade gold-silver zones at the Burns property also contain galena mineralization. It is likely that the galena contains appreciable silver, as is common in many poly metallic districts worldwide.

Bayfield plans to conduct a formal thin section study of the character of the high grade mineralization at the Burns Block in the near future as a first step toward understanding the mineralogical details of the mineralized zones.

Quality Assurance:

Drill core analysis and assaying is being conducted by ACT Labs in Thunder Bay, Ont. The lab is ISO/IEC 17025:2005 (CAN-P-4E) certified. The drill core is split and sampled in standard 0.5 metre to 1.5 metre intervals. The core samples were analyzed for gold by 30-gm fire assay with AA finish and by gravimetric methods from assays over 3000 ppb (over limit). Screened total metallic assays are being performed on samples assaying over 10,000 ppb. The Company has implemented a quality assurance and quality control program to ensure that the sampling and analysis of all samples is conducted in accordance with the best possible practices.
