Project Overview
![]() Regional Setting of the Rainy River Greenstone Belt and Gold Deposits Click to Enlarge The Bayfield Ventures' flagship 100% owned 80 acre "Burns" claim block abuts the eastern boundary of Rainy River Resources (TSX: 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.
![]() Rainy River Gold Exploration Claims Map Click to Enlarge 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.
![]() Rainy River Regional Geology Map Click to Enlarge 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. Discovery 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. The other drill holes were also successful in intersecting gold values and proving the continuity of mineralization from the ODM17 gold zone onto Bayfield's Burns Block. 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.
Drilling on the property has confirmed the widespread distribution of gold and silver within two litho-structural intervals directly on strike with the ODM17 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 and silver 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's June 2011 resource calculation shows a measured and indicated resource of 4.41 million ounces of gold, averaging 1.17 g/t gold, in addition to an inferred resource of 2.33 million ounces of gold, averaging 0.94 g/t gold. Rainy River considers that the material above the final depth of the conceptual pit shell (450 metres vertical depth) offers reasonable prospects for economic extraction from an open pit using a cut-off grade of 0.35 g/t gold. Bayfield continues to be aggressive with its exploration and drilling on the Burns Block. The Company currently has two rigs drilling on the property and is conducting a 100,000 metre diamond drill program. The objective of this major drill program is to explore and expand the extension of gold and silver mineralization that is being defined by Rainy River Resources on their ground adjacent to Bayfield's properties.
Thus far Bayfield has had great success with the 100,000 metre drill program. The Company is delineating lower grade, bulk tonnage gold mineralization as well as higher grade zones with drill results right on par with Rainy River Resources. Early on in the program hole RR10-15 tapped into a high grade gold and silver shoot and returned 31.71 g/t Au over 3.0 metres at 160 metres below surface. The Company quickly followed up this result with another significant drill intercept. Hole RR10-18 intersected 35.93 g/t Au over 10.0 metres . Bonanza grade silver was also intersected in hole RR10-18 totaling 360 g/t Ag over 10 metres including 1760 g/t Ag over 1 metre (gold equivalent intersection of 46 g/t AuEq over 10 metres). Furthermore, the linear plunge distance between the high grade zone in hole RR10-15 and that in hole RR10-18 is in excess of 400 metres indicating a potential for a high grade gold shoot of considerable length on the Burns Block.
![]() Cross Section of Burns Block Looking East Showing Three Seperate Mineralized Zones Click to Enlarge As delineation drilling of the high grade gold-silver shoot continues on the western portion of the Burns Block, more high grade intercepts have been drilled as of late. Hole RR10-52, drilled between RR10-18 and RR10-15, intersected 89.96 g/t Au and 1414.55 g/t Ag over 1.1 metres. Hole 11-1 intersected 33.13 g/t Au and 208.18 g/t Ag over 2.2 metres representing the down-plunge extension of the high grade mineralization in RR10-18. Hole RR11-5 intersected 13 g/t Au and 70.22 g/t Ag over 6.6 metres. The gold-silver zone in RR11-5 represents the up-plunge extension of the high grade mineralization intercepted in RR10-15 as the Company delineates the high grade shoot up towards the surface on the northern part of the property.
In May of 2011, a new east-west exploratory drill fence, known as the Far North Fence, had been established in a position 60 metres north of the existing North Fence. The purpose of the new fence is to test the near surface portion of the mineralized zone that has only partially been delineated on the Burns Block to date. A major gold-silver zone was intercepted in Far North Fence hole RR11-71: 26.70 g/t Au and 170.69 g/t Ag over 25.50 metres including a bonanza grade zone of 11.20 metres of 60.05 g/t Au and 362.96 g/t Ag. The bonanza grade intercept in RR11-71 falls within the up-plunge projection of the modeled mineralized gold-silver shoot on the western portion of the property thereby expanding the known high grade zone to the northeast. The total linear plunge distance between the bonanza grade zones in RR10-18 and RR11-71 is approximately 600 metres. The results strongly support the presence of a discrete structural zone which hosts significant high grade gold-silver mineralization in a SSW-NNE orientation.
Bayfield has recently initiated the drilling of a series of holes drilled on due west azimuths in the northwest corner of the Burns Block. The purpose of these drill holes is two fold: to further delineate known high grade gold and silver zones and to explore for additional electrum bearing fracture zones between the existing pattern of north facing dill holes. The Company has numerous set-ups for these east-west drill holes in order to test the lateral thicknesses and vertical extensions of the bonanza grade gold zones previously intercepted in holes RR11-71, RR10-15, RR10-52 and RR10-18. The initial results from these east-west infill drill holes have been highly encouraging. Drill hole RR11-180 intercepted 30.00 metres grading 12.98 g/t Au and 39.65 g/t Ag at a vertical depth of 40 metres. The length of this intercept demonstrates that the high grade zone intercepted in hole RR11-71 (11.2 metres of 60.05 g/t Au and 362.96 g/t Ag) has significant lateral width to it from east-west. It also illustrates that the high grade drill intercept reported in RR11-71 did not result from down-dip drilling through a narrow high grade structure. This fact is also supported by hole RR11-181 which intercepted 7.20 metres of 61.02 g/t Au. Drill hole RR11-182 intercepted 12.00 metres of 9.53 g/t Au and 31.35 g/t Ag and was drilled 5 degrees below hole RR11-180 from the same collar.
The geometry of the three holes RR11-180, RR11-181 and RR11-182 produces approximately 12 metres of vertical continuity of the high grade zone along with highly variable but significant east-west continuity ranging from 7.2 to 30 metres. This high grade gold and silver zone is near surface and well above 100 metres vertical depth. Three dimensional modeling of the near surface gold and silver intercepts is underway and will be extended to include the total width along the north and far north fences for which mineralization of >5.0 g/t Au has been discovered. This width is currently at approximately 130 metres west to east on the Burns Block. Surrounding the high grade zones on the western portion of the Burns Block is a pervasive, lower grade mineralized envelope. This envelope is significant to the overall value of the gold and silver mineralization hosted at the Burns Block. The mineralization commences immediately under 15 to 25 metres of glacial till cover in the northwest corner of the property. Notable High Grade Drill Intercepts on the Burns Block:
* g/t = grams per metric tonne
The drill program is currently focused on two complimentary exploration efforts. The first being delineation drilling of the high grade gold-silver zones in the west portion of the Burns Block. The second being eastward exploration towards the east portion of the block through a series of four west-east drill fences referred to as the Far North, North, Central and South Drill Fences. This extension drilling on the Burns Block continues to define a thick, pervasive, well-mineralized gold-silver zone. The drilling completed so far has been quite successful in increasing the potential tonnage of gold-silver mineralization that could be included in a larger open pit mining operation. As Bayfield continues to define the extension of the mineralized zone to the east, more detailed follow-up drilling will focus on targeting additional high grade zones and shoots within the mineralized envelope.
The Company'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.

Claim Block "B" Gold-Silver Project
![]() Regional Setting of the Rainy River Greenstone Belt and Gold Deposits Click to Enlarge Bayfield Ventures' "B" claim block, totaling approximately 480 hectares, abuts the eastern boundary of Rainy River Resources' (TSX: 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.

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.
![]() Rodren Drill Rig on B Claim Block Click to Enlarge 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 Bayfield's "B" claim block. 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's June 2011 resource calculation shows a measured and indicated resource of 4.41 million ounces of gold, averaging 1.17 g/t gold, in addition to an inferred resource of 2.33 million ounces of gold, averaging 0.94 g/t gold. Rainy River considers that the material above the final depth of the conceptual pit shell (450 metres vertical depth) offers reasonable prospects for economic extraction from an open pit using a cut-off grade of 0.35 g/t gold.
Bayfield is currently carrying out a 100,000 metre diamond drill program. 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. The drilling will focus on confirming gold continuity and grade at both shallow and deeper depths.

Claim Block "C" Gold-Silver Project
Bayfield Ventures' "C" claim block, consisting of 49 units totaling approximately 800 hectares, abuts the western boundary of Rainy River Resources' (TSX: 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. Rainy River's June 2011 resource calculation shows a measured and indicated resource of 4.41 million ounces of gold, averaging 1.17 g/t gold, in addition to an inferred resource of 2.33 million ounces of gold, averaging 0.94 g/t gold. Rainy River considers that the material above the final depth of the conceptual pit shell (450 metres vertical depth) offers reasonable prospects for economic extraction from an open pit using a cut-off grade of 0.35 g/t gold.
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. 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.
Bayfield contracted Geotech Ltd. to fly a combined VTEM and high sensitivity cesium magnetometer survey over its Burns, "B" and "C" Block properties in mid-December 2010. A total of 308 line kilometres were flown in the survey. Data from the survey was used to advance the understanding of the structural geology of the surveyed areas as well as to provide specific drill targets at discrete conductors, resistors and structural intersections. The survey was flown in two distinct blocks, an eastern block covering the Burns and "B" Block exploration areas and a western block covering the large "C" Block exploration area. Interpretation of the data on the western block is complete and numerous drill targets have been identified on the "C" Block. The cesium magnetic data from the "C" Block survey show clear evidence of mafic volcanic rocks in the northern portion of the property. These rocks are separated from interpreted intermediate volcanic rocks by a sharp contact that is very likely a fault. The interpreted fault contact and the area of interpreted intermediate volcanic (dacite or equivalent) rocks present top quality drill targets at the "C" Block. Drill testing of this area is planned for the beginning of 2012.
