Seafield Resources Drills 152.6 m at 1.03 g/t Au including 12 m at 3.66 g/t Au at its Miraflores Deposit in the Quinchia District, Colombia06:30 EST Wednesday, November 07, 2012TORONTO, ONTARIO--(Marketwire - Nov. 7, 2012) -Seafield Resources Ltd. ("Seafield" or "the Company") (TSX VENTURE:SFF) is pleased to announce further results from the completed 4,697-metre diamond drill program at the Company's Miraflores Deposit ("the Deposit") in the Quinchía District, Department of Risaralda, Colombia. The Company's infill drilling program returned moderate to high-grade mineralization in significant intervals. Seafield plans to gain more confidence in the high-grade veins identified within the Deposit to further delineate its resource as it moves its project towards feasibility level. Highlights:Drill hole QM-DH-37 intersected 152.6 m at 1.03 g/t Au, including 12 m of 3.66 g/t Au;Drill hole QM-DH-36 intersected 65.8 m at 1.01 g/t Au, including 25.3 m at 1.63 g/t Au and 14 m at 3.2 g/t Au and 141 m of 0.89 g/t Au, including 4.35 m at 7.93 g/t Au; QM-DH-37 was drilled from northeast of the Miraflores breccia pipe as part of Seafield's infill drill program aimed at improving the confidence in the Deposit's current resource. This drill hole confirms that mineralization extends 50 metres northeast from what was intersected in drill hole QM-DH-15 (0.8 g/t Au over 261.9 m, including 1.45 g/t over 43.1 m and 1.35 g/t over 41.7 m, press released on October 31, 2011); QM-DH-36 was drilled from northeast border of the breccia pipe and confirms the extension and continuity of mineralization intercepted 30 m to the south of drill-hole QM-DH-13 (1.71 g/t Au over 17.4, 1.43 g/t over 16.3 m and 0.83 g/t over 20.45 m, press released October 31, 2011); To further delineate the resource as the project moves towards feasibility level, an 8,000-metre drill program consisting of 1,500 metres of underground drilling and 6,500 metres of surface infill drilling has recently been initiated.Details: Seafield's Miraflores Deposit is situated in the Company's 6,757-hectare, Quinchía Gold Project. Miraflores is a low sulphidation epithermal deposit located in Colombia's mineral-prolific Mid-Cauca gold belt. The Deposit's mineralization is characterized by a hydrothermal breccia pipe with free gold associated with cement materials (the matrix) and high-grade structures where gold is associated with zinc, lead, copper and iron. At surface, the breccia pipe has a drill-tested diameter of 250 metres by 280 metres. The breccia pipe widens and remains open at depth with a drill-tested vertical extent of 600 metres.The Deposit currently hosts a NI 43-101 compliant Measured and Indicated resource of 77.8 million tonnes averaging 0.8 g/t Au for contained gold of 1.9 million ounces and an inferred resource of 5.5 million tonnes averaging 0.6 g/t Au for 103,043 ounces of contained gold. A 0.3 g/t Au cut-off grade was used for the estimate as reported in the Company's press release on January 31, 2012.Miraflores presents robust economics as indicated in a Preliminary Economic Assessment ("PEA") on the Deposit that was completed by SRK Consulting in Denver on April 23, 2012. The indicated economics for the Deposit include a pre-tax IRR of 50%, an NPV (8%) of $249 million and a payback period of 1.8 years. SRK considers that portions of the Miraflores gold deposit are amenable to open pit mining, while other portions are amenable to underground mining methods. The proposed mine development in the PEA was prepared to best fit Seafield's corporate strategy focused on a medium sized operation that results in solid value accretion (as measured by NPV), moderate capital usage, and manageable environmental and social programs.The Company cautions that the PEA is preliminary in nature, and is based on technical and economic assumptions which will be evaluated in more advanced studies. The PEA is based on a resource model that contains Measured, Indicated and Inferred mineral resources. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.The assays reported in this press release represents the results from three diamond drill holes, which accounts for 1,065 m of a total 4,697 m drilled since January 2012 (See Figure 1). "We are excited to move in the next stages of bringing Miraflores towards feasibility level," commented Cesar Lopez, CEO of Seafield. "We have commenced our next phase of drilling, which will provide a consistent flow of news to our shareholders in the next few months and give us more information on the high-grade structures within the breccia pipe." QM-DH-35, QM-DH-36 (See Figure 2) and QM-DH-37 (See Figure 3) were completed as part of Seafield's infill and breccia definition drilling program at Miraflores. The Company's completed 4,697-metre drill program was aimed at further verifying the geometry and continuity of the breccia pipe as well as the high-grade structures within it. All information from the completed drill program and the recently initiated 8,000 metres of drilling will be used to develop a more robust geological model for Miraflores' resource at feasibility level.Table 1 below summarizes the results of diamond drill holes QM-DH-35, QM-DH-36 and QM-DH-37:Table 1 - Drill Results:Drill HoleFrom (m)To (m)Interval (m)Au (g/t)QM-DH-35024.524.50.38AND60.487.527.10.66AND92.2108.616.40.54AND118.5144.826.30.56AND150.217726.80.44AND191.6207.6160.35AND219.6239.6200.35AND265.6275.6100.39QM-DH-36221631410.89Including67.7572.14.357.93AND173238.865.81.01Including194.8220.125.31.63AND244.8265.120.30.71AND312.8326.8143.20QM-DH-3710110760.90AND180193.8513.850.35AND198.4234.836.40.81AND238.8391.4152.61.03Including281.6293.6123.66Including341.6351.29.61.54Note: Only continual intervals of mineralization above 6 metres with a cut-off grade of 0.2 g/t Au are reported.

Mr. Ortiz is a Fellow of the Australasian Institute of Mining and Metallurgy (Membership # 304612) a professional association and designation recognized by the Canadian regulatory authorities. Mr. Ortiz verified the data disclosed in this release, including the sampling, analytical and test data underlying the information contained in this release. Verification included a review and validation of the applicable assay databases and reviews of assay certificates.The core samples were split by rock saw, and half of the core was sampled. Core samples were prepared by SGS laboratory in Medellin and were assayed at the SGS laboratory in Lima, Peru. Gold was analyzed by fire assay on a 30 gram sample with atomic adsorption spectrophotometer (AAS) finish. Samples above 5.0 g/t Au were repeated by fire assay on a 30 gram sample with gravimetric finish. Multi-elements were analyzed by inductively coupled plasma mass spectroscopy (ICP-MS) following multi-acid digestion. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control.For additional technical information on the Miraflores Deposit, please refer to the Company's technical report (the "Technical Report") entitled "Technical Report, Seafield Resources Ltd., Quinchía Project, Quinchía District, Republic Colombia" dated January 31, 2012, prepared by Scott E.
