NEWS RELEASE
September 7, 2010
Bayfield Drills 35.93 g/t Au over 10.0m within
13.28 g/t Au over 28.0m in Rainy River, NW Ontario
Vancouver, BC - Bayfield Ventures Corp. (TSX-V: BYV) (FWB: B4N) (the "Company")
is pleased to announce an additional high grade gold discovery on its 100% owned
Burns Block property in the Rainy River District of north-western Ontario. The
Burns Block is situated immediately to the east and on strike to Rainy River
Resources' (TSX-V: RR) gold project.

Highlights:
* Another significant high grade gold discovery early in 20,000+ metre (50+
holes) diamond drill program
* 35.93 g/t gold over 10.0 metres within 13.28 g/t gold over 28.0 metres
intersected in hole RR10-18
* The linear "plunge distance" between the high grade zone in the previously
reported hole, RR10-15, and that in the newly reported hole, RR10-18, is in
excess of 400 metres indicating a potential for a high grade gold shoot of
considerable length
* The map distance between the collars of RR10-15 and RR10-18 is approximately
125 metres; little drilling between the holes has been done
* 13 additional holes completed; assays pending
Drill hole RR10-18 has intersected high grade gold mineralization within the
upper portion of a lapilli tuff unit from 488 metres to 516 metres down hole.
The intercept totals 28.0 metres at 13.28 g/t gold and includes 10.0 metres of
35.93 g/t gold. The hole targeted the down-dip extension of the 283 Gold Zone in
the southern portion of the Burns Block. The 283 Zone was initially discovered
by Rainy River Resources in 2008 during their drill program on the Burns Block
and is interpreted to be an eastward extension of Rainy River Resources' ODM17
Gold Zone (see Rainy River Resources' news release dated September 16, 2008:
http://www.bayfieldventures.com/i/pdf/NR-RR-Burns.pdf). The Bayfield news
release of August 18, 2010 reported the results from the first four holes in the
current 20,000+ metre drill program, which were all drilled into the 283 Zone
and all intersected gold. These results were highly encouraging and prompted
Bayfield to do more drilling into the zone.
The gold mineralization in RR10-18 continues to show that very high gold grades
do occur within broad, mineralized envelopes. The best indication of this fact
is that the very high grade 11 metre interval reported in hole RR10-18 is
contained within 81 metres of altered volcanic rock grading 2.70 g/t gold.
Bayfield has partially delineated two of these envelopes on the Burns Block, the
283 and West Gold Zones, and is currently in the initial stages with a second
drill rig of exploring a similar zone of gold mineralization on its 100% owned
"B" Block property immediately to the northeast of the Burns Block.

Bayfield believes that the West and 283 Gold Zones are, in fact, the up-dip and
down-dip extensions of a single, south dipping zone of gold mineralization.
Additionally, the initial examination of the position and geologic setting of
the high grade gold intercept in RR10-18 strongly suggests that this
mineralization represents the down plunge extension of the mineralized 606 High
Grade Zone in hole RR10-15 which intersected 31.71 g/t gold over 3.0 metres
within 12.88 g/t gold over 9.0 metres (see Bayfield's news release of August
24, 2010). The linear distance between the shallow high grade zone in RR10-15
and the deeper high grade zone in RR10-18 reported here is in excess of 400
metres. The plotted geometry of the two intercepts strongly indicates that a
high grade gold shoot of a size, thickness and grade similar to those being
delineated by Rainy River Resources to the west has been found by Bayfield on
the Burns Block.
Infill drilling of the high grade shoot will commence as soon as the drill rig
has completed a critically important fence of drill holes in the northern
section of the Burns Block. This current fence of holes is exploring the up-dip
portion of the West Gold Zone and has been slightly modified to also explore for
the up-dip portion of the 606 High Grade Zone in hole RR10-15.
Significant gold intercepts from the latest batch of assay results for holes
RR10-17 and RR10-18 are listed in the table below. Hole RR10-17 was drilled from
the same collar as RR10-18. Due to the flatter dip of hole RR10-17, the
distance between it and hole RR10-18 is approximately 100 metres (EOH) in the
area of the strong mineralization of RR10-18. This distance is important in
putting the 250 ppb to 1100 ppb gold mineralization in RR10-17 in perspective.
It appears that this low grade mineralization represents a portion of the
mineralized envelope around the highly mineralized zone in hole RR10-18.

Hole RR10-18 was drilled to the north at an initial inclination of 88 degrees.
The hole flattened to an inclination of 79 degrees towards the end of the hole
at 550 metres. Based on the details of core logging of the gold zone in RR10-18,
as well as logging results from surrounding holes, the true width of the 10.0
metre down hole interval grading 35.93 g/t gold is estimated to be 80% of true
width. This estimate compares very well with the estimated 9.0 metre true width
of the zone in hole RR10-15.
Geologic Character of the High Grade Gold Zone
Numerous fine grains (to 2 mm) of visible gold occur in the highest grade
portions of the intersection. This mineralogical data, as in the high grade gold
zone in RR10-15, strongly suggests that the intersection is not based on
sporadic occurrence of very coarse gold but rather due to the presence of
pervasive mineralization of microscopic to locally visible gold within the
entire zone.
The new gold zone contains moderate to abundant pyrite, sphalerite and intense
sericite alteration of the lapilli tuff host rock. The sulfides occur as
stringer veinlets and clots, typical of other mineralized zones in the Rainy
River area. The zone is strongly deformed and contains scattered quartz
veinlets. Fine grained grey sulfides up to 0.5% occur in the high grade
interval. This mineral is tentatively identified as galena. Silver assays of
the high grade portions of both holes RR10-15 and RR10-18 are currently being
completed due to the very strong correlation of the presence of galena and
silver values >100 ppm.
Rainy River regional geology map:
http://www.bayfieldventures.com/i/maps/Burns-B-Geology.jpg
The mineralization is localized within the upper portion of a distinctive
volcanic lapilli tuff unit within the dominantly intermediate to felsic volcanic
rock sequence of the property. This consistent stratigraphic location of strong
sericite alteration and abundant gold and sulfide mineralization was first
recognized by Bayfield during the 2010 winter drill program at the Burns Block.
The mineralization thus has a generally stratabound geometry. However, other
crosscutting features, including intense foliation and the presence of quartz
veinlets within the mineralized zones strongly suggest structural control of the
gold zones, as is typical of the vast majority of gold deposits found in Archean
aged rocks worldwide.
Discussion of Assay Results
Bayfield is in the process of studying all data from the strongly mineralized
intercept in hole RR10-18. As was mentioned earlier, the position of the new
intercept in RR10-18 relative to that in RR10-15 fits very well with the
geometry of high grade gold shoots currently being delineated by Rainy River
Resources immediately to the west of the Burns Block. It is very likely that the
high grade zone intersected at depth in hole RR10-18 is the down plunge
extension of the 606 High Grade Gold Zone. In both cases, the high grade gold
mineralization occurs within large zones of more disseminated gold
mineralization.
Jim Pettit, CEO of Bayfield Ventures, stated: "We are elated to have hit another
high grade gold intercept in only the 11(th) hole drilled in the current 50+
hole program. Bayfield continues to intersect gold zones on its Burns Block at
both shallower and deeper depths. We are now more confident than ever that with
continued drilling, a significant gold resource can be delineated on the Burns
Block."
Exploration Potential
The discovery of additional high grade gold mineralization on the Burns Block
property fully confirms Bayfield's earlier assessments of the exploration
potential of the ground and that the mineralization at the Burns Block is the
direct eastward extension of Rainy River Resources' adjacent ODM17 Gold Zone.
The linear, down plunge, distance between the shallower high grade intercept in
RR10-15 and the deeper high grade intercept in RR10-18 is in excess of 400
metres. A detailed, 3 dimensional, study of all drilling data in the area of the
intercepts is underway in order to provide more data on the potential shape and
possible connection of the high grade zones. This study will result in the
identification of a series of drill locations designed to expand the high grade
gold zones and to explore for the potential connection of them in a plunging
gold shoot.
Bayfield is still at a very early stage of exploration on both the Burns and the
"B" Block properties. The Company has developed plans to continue to explore for
the eastward strike expansion of mineralized zones at the Burns Block as well as
to explore for higher grade gold zones throughout both properties. The plans at
the Burns Block are being guided by the recognition of the importance of the
upper portion of the distinctive lapilli tuff unit as described above. The
structure strikes approximately east-west and dips south. This geometry bodes
well for additional discoveries in the central and eastern portions of the Burns
Block. The setting of the known gold mineralization at the "B" Block is
currently being evaluated based on data from the initial pair of holes completed
there.
Bayfield feels that its current exploration method of drilling to establish the
presence of lower grade gold envelopes followed by infill drilling to define
higher grade gold zones is working well. This exploration method will be applied
at both the Burns and the "B" Blocks as the exploration of both properties
advances.
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 metre intervals. The core samples were
analyzed for gold by 30-gm fire assay with AA finish and by gravimetric methods
from assays over 3,000 ppb (over limit). Screened total metallic assays are
being performed on samples assaying over 5,000 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.
