Bayfield Ventures Corp. (TSX-V: BYV) is exploring for gold in the Rainy
River district of northwestern Ontario.

Bayfield's 100% owned "Burns" block property is located in the Richardson Township, Rainy River District of northwestern Ontario. The property is
surrounded by Rainy River Resources (TSX-V: RR) and adjoins the immediate east of Rainy River Resources' main ODM17 gold zone.

The Bayfield Ventures' "Burns" claim block abuts the eastern boundary of Rainy River Resources (TSX-V: RR) main ODM17 gold zone Richardson Township property in northwestern Ontario. Access to the "Burns" property is attained via numerous all-weather, secondary provincial highways (gravel) and township roads, which lead off of paved provincial highways 11 and 71. These routes traverse the region and provide excellent ingress to the property.

The property is located near the international boundary with Minnesota. The
nearest population centre is Fort Frances, 50 km to the southwest.
Bayfield's properties lie within the Rainy River Greenstone Belt. This belt
is one component of the western part of the Archean Wabigoon Subprovince of
the Canadian Shield, a 900 km long east-west trending
metavolcanic-metasedimentary domain bordered and intruded by granitoid
intrusions of up to batholithic dimensions. The Wabigoon Subprovince is
composed of several tectonically bounded assemblages consisting of
komatiitic to calc-alkalic metavolcanics overlain by clastic and minor
chemical sediments. Intrusion of the granitoid domes has imparted a
synformal structural character to the supracrustal rocks, and the central
axial zones of many of these synformal belts may be characterized by long
sinuous shear / fault zones.

In the fall of 2008, Rainy River Resources, under an option agreement,
completed a diamond drill program on Bayfield's "Burns" claim block. Rainy
River Resources managed to complete 8 drill holes totaling 3332 metres at a
cost of $420,000 on Bayfield's "Burns" property. The "Burns" property
drilling concentrated on tracing the strike and extension of the ODM17 gold
zone which crosses under highway 600, as well as to trace the down dip of
Rainy River's drill hole NR08-280. 

Hole NR08-283 was collared near the eastern boundary of Rainy River
Resources' property but deviated eastward where, approximately 30 metres
inside Bayfield's "Burns" property at the -420 metre level, it intersected a
4.5 metre interval grading 7.34 g/t gold within 10.5 metres grading 3.54 g/t
gold. Drill hole NR08-294, targeting the relatively high-grade assay
intervals in hole NR08-280, intersected a 4.5 metre interval grading 2.24
g/t gold of the down-dip extension of the zone at the 263 metre level. The
holes NR08-296 and NR08-304 targeted the east extension of the ODM17 zone
intersected in hole NR08-283. NR08-296 cut a broad 25 metre interval grading
0.89 g/t gold. Hole NR08-304 intersected 43.5 metres grading 0.78 g/t gold
including two zones from 178.5 to 183 metres and 204 to 208.5 metres grading
2.0 g/t gold and 3.0 g/t gold respectively.

The option agreement was subsequently terminated when Rainy River Resources
failed to spend the required exploration expenditures by November 2008 and
Bayfield now holds a 100% ownership in the property. 

In February 2010, three diamond drill holes totalling 1509 metres were
completed on the Burns Block property by Bayfield. The holes were along the
western edge of the property and completed a section immediately on strike
with the eastern end of the "ODM17" Zone of Rainy River Resources. All three
holes encountered gold values in the same litho-structural settings that
host the ODM17 Zone and North Zone on Rainy River Resources' property. Gold
mineralization is widespread within a sheared felsic pyroclastic sequence.
Gold grade appears to be strongly influenced by proximity to the margins of
strong sericitic alteration within the shear system. The drilling to date
has shown that the ODM17 Zone extends from Rainy River Resources' ground
onto the Burns Block.

The first hole in this drill program, RR10-1, encountered 61.2 metres of
0.49 g/t gold including 7.5 metres of 1.77 g/t gold within 16.5 metres of
1.20 g/t gold. RR10-2 intersected a 12 metre interval of 0.54 g/t gold at a
depth of 324 metres. These intercepts relate directly to the extension of
the ODM17 Zone onto the Burns block. RR10-3 targeted the down dip of the
North Zone of Rainy River Resources and encountered a 7.0 metre interval
grading 0.72 g/t gold, a 1 metre interval grading 4.83 g/t gold, and a 1
metre interval grading 9.51 g/t gold at a depth of 728 metres to 745 metres.

Drilling on the property has confirmed the widespread distribution of gold
within two litho-structural intervals directly on strike with the ODM17 Zone
and North Zone of Rainy River Resources. Both shallow and deeper (below
potential open pit parameters) intercepts reported by Bayfield Ventures
along the strike extension of the ODM17 Zone of Rainy River Resources
indicate that well above gold cut-off grade material continues onto the
Burns Block. 

The zones of mineralization occur in felsic metavolcanics within zones of
stronger penetrative foliation. The foliation is near coincident with the
strike and dip of the lithologies. Gold grade appears to be strongly
influenced by proximity to the margins of strong sericitic alteration within
the shear system. The zones strike at 120 degrees and dip at around 50
degrees to the southeast on the Burns Block property.

Bayfield currently has two rigs drilling on its Rainy River properties, one
on the Burns Block and one on the "B" Block, to carry out the Company's
20,000+ metres of diamond drilling. The objective of this major drill
program is to explore and expand the extension of gold mineralization that
is being defined by Rainy River Resources on their ground adjacent to
Bayfield's properties. With $3.5 million in its treasury, Bayfield is well
financed to carry out the drilling.

 The "B" claim property is located near the international boundary with
Minnesota. The nearest population centre is Fort Frances, 50 km to the
southwest. Bayfield's properties lie within the Rainy River Greenstone Belt.
This belt is one component of the western part of the Archean Wabigoon
Subprovince of the Canadian Shield, a 900 km long east-west trending
metavolcanic-metasedimentary domain bordered and intruded by granitoid
intrusions of up to batholithic dimensions. The Wabigoon Subprovince is
composed of several tectonically bounded assemblages consisting of
komatiitic to calc-alkalic metavolcanics overlain by clastic and minor
chemical sediments. Intrusion of the granitoid domes has imparted a
synformal structural character to the supracrustal rocks, and the central
axial zones of many of these synformal belts may be characterized by long
sinuous shear / fault zones.

Compilations of historic geological and geographical data of exploration work conducted on claim block "B" indicates 3 -- 4 high priority airborne EM conductors that are coincident with a strong IP conductive zone identified from ground survey data shown below.

In December 2008, Bayfield Ventures completed a 4 hole drill program (1192
metres in total) concentrated in the southwest corner of the "B" claim
block. Mineralization on the "B" claim block was encountered in felsic
pyroclastics flanking a strong north-south trending growth fault on the
property. The fault is the most easterly of a series of north-south trending
faults in the area. A number of distinct pebbly pyroclastic units abut this
fault and trend off to the southwest. 

All four holes, although shallow, encountered wide sections of elevated to
strongly anomalous gold values including a 2 metre intercept grading 5.70
g/t gold within 5 metres of 2.64 g/t gold, and a 1 metre intercept grading
1.95 g/t gold. The gold values are typically associated with sulfides and
elevated zinc values.

Hole RR08-1 encountered elevated to strongly anomalous gold values of 200
ppb to 1900 ppb Au over 38.8 metres from 92 metres to 130.8 metres,
including 1.95 g/t Au over 1 metre from 99.7 metres to 100.7 metres. Hole
RR08-2 encountered elevated to strongly anomalous gold values over a 21
metre intersection from 251 metres to 272 metres including 5.7 g/t Au (.17
oz/t Au) over 2 metres within 5 metres of 2.64 g/t Au. Hole RR08-3
encountered elevated to strongly anomalous gold values from 177 metres to
188 metres. Hole RR08-4 encountered elevated to strongly anomalous gold
values of 200 ppb to 900 ppb Au over 28 metres from 26.5 metres to 54.5
metres. 

The mineralization encountered on Bayfield's "B" claim block occurs in an
environment similar to that hosting gold values on Bayfield's Burns Block
and on the main ODM17 Zone of Rainy River Resources, all to the southwest.
It is very likely that some of the lithological units are correlative across
the area. All of this augers well for defining deposit scale mineralization
on ground held by Bayfield Ventures in the immediate area. The Company is of
the opinion that the highly altered dacitic tuff breccia zone, seen in Rainy
River Resources' core, continues in an easterly trend onto the "B" claim
block held 100% by Bayfield Ventures.

Bayfield Ventures' "C" claim block, consisting of 49 units totaling
approximately 800 hectares, abuts the western boundary of Rainy River Resources' (TSX-V: RR) Rainy River Resources (TSX-V: RR) Richardson Township property in northwestern Ontario. Access to the property
is attained via numerous all-weather, secondary provincial highways (gravel)
and township roads, which lead off of paved provincial highways 11 and 71.
These routes traverse the region and provide excellent ingress to the
property.

The Company completed a 2008 winter exploration program on its Claim Block
"C" property in the Rainy River District of northwestern Ontario.

A tightly spaced line-cut grid consisting of approximately 70 kilometres was
established on the Claim Block "C" property. Bayfield Ventures carried out a
detailed Magnetometer survey and an Electro-Magnetic (EM) survey with Dan
Patrie Explorations. The geophysical program was designed to establish
targets that will be diamond drilled. The property has a large area of low
lying acreage and swampland, so the work program was designed to utilize
winter access to the maximum and to allow a comprehensive drill program to
follow.

Rainy River Resources' March 2010 NI 43-101 shows an indicated resource of
2.37 million ounces of gold (averaged at 1.3 g/t) and inferred resources of
2.66 million ounces of gold (averaged at 1.2 g/t). Of the total 5.03 million
ounces Au inferred and indicated, 4.09 million ounces Au are contained
within open pit parameters and the remaining 0.94 million ounces Au are
below open pit depths. 

Bayfield's properties are ideally located with easy access to roads and
power. Ontario has low political risk and the Rainy River District has
skilled labour and is one of the lowest-cost areas for mineral exploration
and development in Canada.
