Seafield Announces the Discovery of a New Porphyry-Style Drill Target at its Quinchia Gold Project in Risaralda, Colombia06:30 EDT Thursday, September 27, 2012TORONTO, ONTARIO--(Marketwire - Sept. 27, 2012) -Seafield Resources Ltd. ("Seafield" or "the Company") (TSX VENTURE:SFF) is pleased to announce the discovery of a new porphyry-style drill target within its Quinchía Gold Project in Risaralda, Colombia. The new target zone, Tesorito, is situated 800 metres southeast of the Miraflores gold deposit at an elevation of approximately 1,200 metres above sea level (See Figure 1). Highlights Assay results of 565 rock samples taken from the Tesorito target zone include: 18.0 m at 1.03 g/t Au and 0.09 % Cu7.0 m at 0.84 g/t Au and 0.02% Cu16.0 m at 1.0 g/t Au and 0.02% Cu Porphyry-style target at Tesorito has an anomalous area of 500 m by 700 m Details: Tesorito Target Zone: Arce Geofísicos of Perú was commissioned by the Company to conduct induced polarization (IP) study and rock chip channel sampling in the Tesorito target zone. The IP survey:covered a rectangular area oriented east to west measuring 1.4 km by 1 km; was conducted with a pole-dipole array and a dipole spacing of 50 metres; and consisted of 10 survey lines with a 90° azimuth and constant spacing between lines of 100 m. A total of 14 km of IP data was collected.IP survey in the Tesorito target zone presented anomalies with high values of chargeability (See Figure 2.1), which can be associated with high contents of sulfides and/or the presence of hydrothermal alteration clays. The anomaly covers an area of 500 metres by 700 metres and is stronger 50 metres below the surface to the west of the area indicating anomalous values of gold in rocks. The chargeability and resistivity pattern observed in this anomaly (See Figures 2.1 and 2.2) suggest the potential extension of porphyry stock observed at surface. At least two intrusive bodies have been mapped in the mineralization observed at surface. An aphyric textured diorite intruded by coarse-grained dacitic porphyry found in Tesorito is similar to one found near Seafield's Miraflores breccia pipe. Both intrusives are emplaced into the massive basalts of the Barroso Formation. Gold is believed to occur in magnetite, quartz-magnetite and quartz-pyrite and sulfides microveinlets, veinlets and stockworks, sheeted with dissemination of sulfides. Additionally, gold is also related to structural zones defined by brittle rock and fault gouge. Some potassic hydrothermal alteration is observed and locally overprinted by choritic and argillic alterations. Assay results of 565 rock samples (See Figure 3) taken from the Tesorito target zone included intervals of 18.0 metres averaging of 1 g/t Au and 0.09% Cu (See Table 1), 7.0 metres averaging 0.84 g/t Au and 0.02% Cu (See Table 2) and 16.0 metres averaging 1 g/t Au and 0.02% Cu (See Table 3). All assays came from rock chip channel samples collected along road cuts and creeks. The following tables present details of the intervals outlined above:TABLE 1: 0.84 g/t Au and 0.024% Cu over 7 mSampleInterval (m)Au (g/t)Cu (%)D-1668420.310.013D-1668521.850.031D-1668620.590.030D-1668710.390.02TABLE 2: 1.03 g/t Au and 0.09% Cu over 18 mSampleInterval (m)Au (g/t)Cu (%)R-0034720.610.050R-0034820.410.034R-0034920.430.047R-0035021.030.069R-0035121.480.114R-0035222.170.140R-0035321.220.143R-0035421.250.112R-0035520.710.078TABLE 3: 1 g/t Au and 0.024% Cu over 16 mSampleInterval (m)Au (g/t)Cu (%)R-155020.440.024R-155121.870.024R-155220.730.015R-155320.450.017R-155521.660.022R-155620.610.031R-155721.480.029R-155820.790.027In Q1 2013, an initial 1,500-metre drilling program will be executed in the Tesorito target zone. The drill program will test the continuity of the surface mineralization at depth and examine the chargeability anomaly from the IP survey. "This is a very exciting time for Seafield. In addition to advancing our Miraflores deposit towards development stage, we now have another potential porphyry-style deposit in our concession," commented Cesar Lopez, CEO of Seafield. "This adds tremendous value to our project and confirms our confidence that there are other mineralized zones within our sizable land package. We will be conducting further regional exploration work and look forward to the possibility of expanding the known mineralized areas within the Quinchía project."Other Target Zones: Five additional potential target zones (Santa Sofia, La Loma, Naranjal, Miracielo and Sausagua) have been found along the northwest to southeast trend in Seafield's 6,757-hectare concession. Geochemical sampling, including soil and stream sediment sampling, indicates several anomalies in these zones (See Figure 1). Detailed geological mapping, trenching, surface geophysical surveys, and additional sampling will be performed in the prospective areas over the coming months to evaluate and delineate the anomalous gold values currently observed there.
