NEWS RELEASE
March 28, 2012
Bayfield Reports 7.5m of 7.31 g/t Au, 107.95 g/t Ag and 7.9m of 4.8 g/t Au,
43.5 g/t Ag in Expanding Discovery Zone at Burns Block in Rainy River, NW
Ontario
Vancouver, BC - Bayfield Ventures Corp. (TSX-V: BYV) (OTC Pink: BYVVF) (the
"Company") is pleased to announce additional assays from the continuing early
stage exploration of an expanding, significant zone of gold and silver
mineralization in the eastern portion of the Burns Block. The Company's 100%
owned Burns Block gold-silver project is located in the Rainy River District of
north-western Ontario and is situated adjacent to the east and on strike to
Rainy River Resources' (TSX: RR) multi-million ounce gold-silver deposit.
The new gold-silver zone is hosted within strongly sheared and altered dacite
volcanic units located 600-700 metres to the east of Bayfield's high grade gold-
silver zones and appears to be the easterly strike extension of the main ODM17
gold-silver zone which hosts Rainy River's deposit.
Rainy River District Gold Zones:
http://www.bayfieldventures.com/i/pdf/RR-Gold-Zones.pdf
The assay results for holes RR12-6, RR12-7 and RR12-8 detailed in this news
release continue to show that strong gold and silver mineralization is present
over an expanding area, both up and down dip and along strike in the east-
central Burns Block.
This developing new zone remains more gold dominant than the western Burns area
however, local zones of very high grade silver mineralization are now being
found along with multi-gram gold values. The appearance of these silver rich
zones in the east is very reminiscent of our exploration experience in the early
delineation stage of the western portion of the Burns Block.
Highlights:
* Hole RR12-7 intercepted 10.5 metres of 5.28 g/t Au and 77.82 g/t Ag
including 7.5 metres of 7.31 g/t Au and 107.95 g/t Ag starting at 545 metres
down hole.
* Hole RR12-8 intercepted 11.0 metres of 3.8 g/t Au and 26.98 g/t Ag including
7.9 metres of 4.77 g/t Au and 43.47 g/t Ag starting at 506 metres down
hole.
* Hole RR12-6 was drilled up dip of the strong mineralization previously
reported in hole RR12-5 and intercepted 7.0 metres of 0.60 g/t Au and 7.44
g/t Ag. See discussion of this lower grade intercept in the section below.
* Mineralization is being found within a 50 to 60 metre wide zone of shearing,
sericite-silica alteration and polymetallic base metal sulfide and local
electrum mineralization.
* This east-central zone of mineralization is completely open down dip and
down the likely SSW plunge. The zone is also open onto Rainy River
Resources' land to the east.
* A program of re-assaying higher grade silver zones at the Burns Block using
screen fire metallic methods is showing a clear trend of higher to much
higher silver assay values with the 500 gram pulp screen fire metallic
method vs. the previously reported 30 gram pulp gravimetric silver assay
method. This re-assay program is being expanded.
Eastern Burns Block Early-Stage Exploration/Delineation Discussion:
Bayfield is advancing the initial exploration and delineation of the east-
central Burns Block with drill collar step outs ranging from 30 to 75 metres.
This relatively wide spaced drilling is being done to test the conceptual model
of a SSW plunging higher grade mineralized zone. The assay results to date,
including those reported here, are confirming that the new east-central zone has
a SSW plunging geometry very similar to that of Bayfield's western high grade
mineralized zone on the Burns Block.

.jpg
We are in the final stages of completing the up-plunge delineation with hole
RR12-9 being completed and hole RR12-10 in progress from a common collar 60
metres north of hole RR12-8. Following completion of this work, the main down-
plunge target area will be targeted for exploration. A highly prospective area
of 200 metres down-plunge and approximately 200 metres in strike length remains
completely undrilled. Much more exploration on 50 metre step-outs will be
required to outline mineralization in the down-plunge target area. Infill
drilling of the entire new mineralized zone will commence once the planned
exploration drilling is completed.
Cross Section of 2012 Drill Holes Looking West at East Burns:
http://www.bayfieldventures.com/i/maps/BurnsBlock-W.jpg
The drill results in the table below present the assay results from the latest
completed holes RR12-6, 7 and 8. Four important points from these results are:
1. The success rate from drilling in the eastern area remains very high.
2. Gold and silver mineralization is showing a pattern of increasing to the
east and south, geometry consistent with a SSW plunging mineralized zone.
3. Higher silver numbers are now being intercepted with hole RR12-7 returning
146.66 g/t Ag over 5.2 metres including 269.37 Ag over 1.9 metres within the
main zone. These high grade silver numbers are very encouraging as they are
similar to those found in and around very high grade zones of gold
mineralization within the western portion of the Burns Block.
4. The lower grade results from hole RR12-6 should be viewed in the context of
the initial exploration and delineation of a new mineralized zone. Shear
zone hosted ore bodies are known to contain locally erratic grade
distribution. This intercept is an anomaly within an area of consistently
higher grade gold and silver mineralization.

* g/t = grams per metric tonne
* The down hole interval lengths are estimated to be approximately 65%-95% of
true width
* AuEq (gold equivalent) values calculated at a 50 to 1 (gold price vs. silver
price) ratio and metallurgical recoveries and net smelter returns are assumed to
be 100%
* The intervals were determined using a 0.35 g/t gold equivalent cut-off grade
with a maximum gap of 3.0 metres between intervals below the cut-off grade
The mineralization at the eastern Burns area is very similar in character to
that found by Bayfield in the western portion of the property where multi-ounce
gold and silver material has been intercepted over significant widths. The gold-
silver mineralization in the eastern area is focused within sheared and altered
dacite volcanic wall rocks and is accompanied by abundant sphalerite, galena and
arsenopyrite with local smears and crack fills of electrum.
Plan View of 2012 Drill Holes at East Burns:
http://www.bayfieldventures.com/i/maps/BurnsBlock-WestHoles.jpg
It should also be noted that Bayfield has recently begun a program of re-
assaying high grade silver zones previously reported in the western area by
screen fire metallic methods using a 500 gram pulp. This much larger sample size
is important when dealing with high grade gold or silver mineralization. Screen
fire assay results from 30 selected samples shows a clear trend of higher to
much higher silver assay values with the screen fire metallic method verse the
previously reported standard gravimetric silver assay methods.
The initial results of this re-assay program appear to indicate that coarse
grained native silver present in some mineralized intervals in the western Burns
area was being sampled by the smaller pulp and the gravimetric assay method. The
500 gram pulp and screen fire metallic assay method are industry standard for
mineralization that includes coarse grained native silver.
This re-assaying was initiated by Bayfield due to comparison of logged zones
containing visible native silver with the assay results of those zones. Detailed
discussions with our assayer, ACT Labs led to a decision to begin a program of
re-assaying using the 500 gram pulp screen fire metallic method.
This program is now being expanded to include additional higher grade silver
zones in the west and will done on all current higher grade silver zones in the
east. A detailed report on the results of this work will be announced as soon as
a significant amount of the re-assaying by screen fire metallic methods is
completed.
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 5,000 ppb (over limit). Screened total metallic assays are
being performed on samples assaying over 5,000 ppb. The core samples were
analyzed for silver by Ag Aqua Regia-ICP finish and Ag Fire Assay-Gravimetric
from assays over 100 ppm (over limit). 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.
