Seafield Intersects 261.9 Metres of 0.80 g/t Gold Including 43.1 Metres of 1.45 g/t at Miraflores Prospect, Quinchia District, Colombia
TORONTO, ONTARIO -- (Marketwire) -- 10/31/11 -- Seafield Resources Ltd. ('the Company' or 'Seafield') (TSX VENTURE: SFF) is pleased to announce assay results from an additional two drill holes at its Miraflores prospect in the multi-million ounce Quinchia District in Colombia.
-- QM-DH-13 intersected 1.71 g/t gold over 17.4 metres, 1.43 g/t gold over
16.3 metres, 0.83 g/t gold over 55.05 metres, 0.85 g/t gold over 20.45
metres and 0.64 g/t gold over 42.7 metres.
-- QM-DH-15 intersected 0.80 g/t gold over 261.9 metres that includes 1.45
g/t gold over 43.1 metres and 1.35 g/t gold over 41.7 metres.
During the period 2005-2007, AngloGold Ashanti Limited and B2Gold Corp. completed 3,624 metres of drilling in ten diamond drill holes at the Miraflores prospect. From 2010 to date, Seafield has completed 9,168 metres in 21 holes. Assay results are pending for QM-DH-14, and QM-DH-16 to QM-DH-21, and the Company expects to report the results from those holes when received. An additional 1,730 metres are planned for the remainder of 2011. The results until November 30th from this year's program will be included in an updated resource estimate and a scoping study being prepared by SRK in its Denver office, targeted for completion by Q1 2012.
The gold mineralization contained in the Miraflores Breccia pipe is characterized by the presence of free gold associated with the cement material of the breccias and to high grade structures where gold is associated with Zn, Pb, Cu and Fe sulphides. At surface, the diameter of the roughly-circular breccia pipe varies from 250 metres to 280 metres. Recently updated geological interpretations indicate that the breccia pipe widens at depth. The mineralization has been tested from surface to 600 m depth and still remains open. The deposit is classified as a low sulphidation epithermal deposit and is part of the prolific Mid Cauca porphyry belt.
The results of the two recent holes (QM-DH-13 and QM-DH-15) at the Miraflores prospect are shown in Table 1. Significant intercepts from drill holes carried out previously by Seafield at Miraflores are shown in table 2.

Note: Grades are uncut except for holes QM-DH-11, 12, where one 2 m
sample in each hole returned a bonanza grade value which was cut to 20
g/t Au. Intervals are calculated using a cut-off grade of 0.1 g/t Au.
Only intervals above 0.3 g/t Au reported.
Encouraging metallurgical test results for gravity concentration have been obtained for Miraflores ore (as previously reported in the company's press release dated September 21, 2011). The Company has engaged Gustavo Meyer, a PhD Metallurgical Engineer from Colombia University with extensive experience in gold ore processing metallurgy. Mr. Meyer is establishing a program that includes the preparation of a geo-metallurgical model of the deposit.
At Miraflores, Seafield has already defined an NI 43-101 compliant resource that includes a Measured and Indicated resource of 1,227,593 ounces gold (44.7 million tonnes grading 0.9 g/t Au at a cut-off grade of 0.3 g/t Au) and an Inferred resource of 354,512 ounces gold (12.2 Million tonnes grading 0.9 g/t Au at a cut-off of 0.3 g/t Au), as previously reported in the company's press release dated May 26, 2011.
The geology and drill locations are presented in Map 1 (see below). A drill plan map and cross sections are available on the Seafield website www.sffresources.com.

Review by Qualified Person, Quality Control and Reports
Tom Henricksen, VP Exploration of Seafield, 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. Dr. Henricksen is a Registered Professional Geologist in the State of Wyoming, USA (Membership # PG-3069) a professional association and designation recognized by the Canadian regulatory authorities. Dr. Henricksen 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.
