Seafield Intercepts Higher Grades in Last 4 Holes of In-Fill Program at Miraflores07:30 EDT Thursday, March 21, 2013TORONTO, ONTARIO--(Marketwire - March 21, 2013) -Seafield Resources Ltd. ("Seafield" or "the Company") (TSX VENTURE:SFF) is pleased to announce assay results from the final four drill holes completed as part of the 6,532.7-metre in-fill diamond drilling program at the Company's Miraflores Deposit in the Quinchía District, Department of Risaralda, Colombia.Highlights:Drill hole QM-DH-52 intersected 174.05 m at 1.15 g/t Au and 1.63 g/t Ag, including 59.95 m at 2.33 g/t Au and 2.62 g/t Ag;Drill hole UM-DH-004 intersected 111.4 m at 1.52 g/t Au and 2.1 g/t Ag, including 23.4 m at 3.91 g/t Au and 3.22 g/t Ag;Drill hole UM-DH-005 intersected 81 m at 1.93 g/t Au and 1.26 g/t Ag, including 17.65 m at 5.35 g/t Au and 2.18 g/t Ag.Details:The results released correspond to four additional diamond drill holes, representing 1,621.5 metres. The infill drilling program commenced in November 2012 and has been completed with 27 drill holes totaling 6,532.7 metres (See Figure 1). Gold and silver mineralization has been intercepted in the four holes reported, which tested horizontal and vertical continuity near surface and deeper mineralization in the breccia pipe and within the high grade veins present in the deposit.Table 1 below summarizes the gold and silver assay results of the four diamond drill holes.Table 1 - Drill Results:Drill HoleFromToIntervalAuAg(m)(m)(m)(g/t)(g/t)QM-DH-5213.427.3513.950.410.89And80.9137.856.90.361.16And140.9181.140.21.031.38And183.6254.6571.051.072.42And256.25430.3174.051.151.63including258.25318.259.952.332.62And480.3491.711.40.411.16QM-DH-55136199.763.70.661.11And221.2256.835.60.401.16And261284.323.32.081.55And312.5324.5120.450.75And340.536423.50.320.68And401.9419.417.50.350.73UM-DH-004621.615.60.531.28And29.6141111.41.522.1including113.613723.43.913.22And149167181.763.34And199.6214.314.70.530.95And224270.846.81.211.07including231.4252.220.82.391.47UM-DH-0055.45159.550.451.12And2145.524.51.231.05And51132811.931.26including101.1118.7517.655.352.18And186.5203.5170.40.75And235.5249.5140.511.11Note: Only continual intervals of mineralization above 6 metres with a cut-off grade of 0.2 g/t Au are reported. Gold grades reported are cut to 20 g/t. Hole QM-DH-52 includes a sample of 49.6 g/t Au over 1.5 m and a sample of 181.0 g/t Au over 2.0 m, Hole QM-DH-55 includes a sample of 26.4 g/t Au over 1.6 m, Hole UM-DH-004 includes a sample of 21.8 g/t Au over 1.5 m, and Hole UM-DH-005 includes a sample of 43.5 g/t Au over 2.0 m.Table 2 - Drill Hole Coordinates:Drill HoleEastingNorthingElevationAzimuthInclinationDepth(m)(m)(m)(°)(°)(m)QM-DH-52423,175.7585,132.71407.7252-56500.0QM-DH-55(**)423,059585,2401,491245-73518.5UM-DH-004(*)423,124585,0981,365255-50285.0UM-DH-005(*)423,139585,0581,364247-32318.0(*)Holes drilled from pads constructed inside the La Cruzada Tunnel in Miraflores.(**)The final 95.2 m of core from hole QM-DH-55 were reserved for geotechnical testing and therefore were not assayed.The azimuth, dip and total length of each drill hole is shown in Table 2. Holes QM-DH-52 and QM-DH-55 were collared inside the breccia. UM-DH-004 and UM-DH-005 were drilled from chambers inside the La Cruzada tunnel, inside the beccia pipe.Figure 1 illustrates a plan view with the location of each hole, and the vertical sections for each hole are shown in Figures 2-5 (see below)."We are pleased to announce the final assay results from the drill program at Miraflores," commented Cesar Lopez, Seafield's President and CEO. "All of the reported assay results will be incorporated into an updated resource estimate which we expect during Q2 2013. Seafield continues to complete the necessary work at Miraflores on schedule and we are excited about the further development of the deposit."Seafield's Miraflores Deposit is situated in the Company's 100%-owned, 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.To view "Figure 1 - Plan View of Miraflores Deposit", please visit the following link: http://media3.marketwire.com/docs/fig1sff.pdf.To view "Figure 2 - Vertical Section of Miraflores Deposit - Hole QM-DH-52", please visit the following link: http://media3.marketwire.com/docs/fig2sff.pdf.To view "Figure 3 - Vertical Section of Miraflores Deposit - Hole QM-DH-55", please visit the following link: http://media3.marketwire.com/docs/fig3sff.pdf.To view "Figure 4 - Vertical Section of Miraflores Deposit - Hole UM-DH-004", please visit the following link: http://media3.marketwire.com/docs/fig4sff.pdf.To view "Figure 5 - Vertical Section of Miraflores Deposit - Hole UM-DH-005", please visit the following link: http://media3.marketwire.com/docs/fig5sff.pdf.Review by Qualified Person, Quality Control and ReportsGiovanny Ortiz, Vice President of Exploration for Seafield Resources Ltd., is a qualified person as defined by National Instrument 43-101 and prepared or reviewed the preparation of the scientific and technical information in this press release with respect to the assay results from the drilling program. 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 ALS Colombia Ltd., in Medellín and were assayed at the ALS laboratory in Lima, Peru. Gold was analyzed by fire assay on a 30 gram sample with atomic adsorption spectrophotometer (AAS) finish. Samples above 10.0 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.
