Claim Block "C" Gold-Silver Project
Bayfield Ventures' "C" claim block, consisting of 49 units totaling approximately 1976 acres, 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 October 2012 resource calculation shows a measured and indicated resource of 6.17 million of gold averaging 1.21 g/t gold, in addition to an inferred resource of 2.28 million ounces of gold averaging 0.75 g/t gold. Rainy River considers that the material above the final depth of the conceptual pit shell (500 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 deposit also contains a measured and indicated resource of 13.34 million ounces of silver averaging 2.62 g/t silver, in addition to an inferred resource of 6.98 million ounces of silver averaging 2.32 g/t silver.
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.

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.
Robert Marvin, P.Geo., CPG, Project Geologist for Bayfield Ventures is the Qualified Person as defined by National Instrument 43-101 and supervised both the project field exploration and the preparation of the technical information on this website.
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.
