| Projects Overview |
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.
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.

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.

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.
Rainy River Resources' March 2010 NI 43-101 resource calculation 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 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.
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.
Bayfield Ventures' "B" claim block, totaling approximately 480 hectares, abuts the eastern boundary of Rainy River Resources' (TSX-V: RR) main 433 gold zone Richardson Township property in northwestern Ontario. Access to the "B" Block 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 "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.
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.
Just to the southwest of the "B" Block a 5.2 metre intercept of 12.17 g/t gold was discovered. More recent drill results reported by Rainy River Resources to the east of their 433 gold zone represent a possible eastward strike extension of the zone. With sufficient drilling, Bayfield is of the opinion that it can prove up this extension of the 433 gold zone eastward onto the "B" Block.
Rainy River Resources' March 2010 NI 43-101 resource calculation 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.

The "C" claim property is located near the international boundary with Minnesota. The nearest population centre is Fort Frances, 50 kilometres 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.
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.
