Seafield Announces Resources of 1,582,105 Ounces Gold at Miraflores Project, Quinchia, Colombia

TORONTO, ONTARIO--(Marketwire - May 26, 2011) - Seafield Resources Ltd. (TSX VENTURE:SFF) ("Seafield" or the "Company,") is pleased to announce an updated NI 43-101 compliant resource estimate for its Miraflores property in the Quinchia district, Colombia. This includes a Measured and Indicated resource of 1,227,593 ounces of gold grading 0.9 g/t gold contained in 44,717,000 tonnes at a cut off grade of 0.3 g/t Au. Additionally, the resource contains an Inferred resource of 354,512 ounces of gold grading 0.9 g/t gold in 12,252,000 tonnes at a cut off grade of 0.3 g/t Au.

This represents a significant increase in all categories, from the previous inferred resource estimate of 776,000 ounces at 1.295 g/t gold in 18,650 million tonnes, at a cut off grade of 0.5 g/t, (see press release dated 20 April 2010). Updated geological interpretations and increased drilling density have moved a significant proportion of the resources into the measured and indicated category.

The mineral resource estimate is based on 7,757 metres of drilling in 22 diamond drill holes and 154 underground channel samples. This includes 4,132 metres in 12 holes completed by Seafield in October 2010 (see press releases of results dated December 2, 1010 and February 14, 2011), and 3,624 metres in 10 holes carried out by AngloGold Ashanti and B2Gold in 2006-2007.

The Miraflores property is located within the Quinchia gold mining district and has been the site of artisanal mining since Pre-Columbian times. The Miraflores deposit occurs within a hydrothermal breccia pipe which is roughly circular in shape, measuring some 280 metres by 250 metres in outcrop. It has been traced by drilling for over 600 metres in vertical extent and remains open at depth. Recently updated geological interpretations show that the breccia pipe is wider at depth than previously thought.

ONGOING WORK PROGRAM

Seafield will shortly start a second drill program at Miraflores for expansion and infill drilling, to define the shape of the deposit better, and to extend the mineralization laterally and at depth, where it remains open. A program of preliminary metallurgical test work is also underway at McClelland Laboratories Inc in Sparks, Nevada.

Drilling continues in the Dosquebradas area of the Seafield property in an area that was previously drilled by Anglo Gold. Results will be released when the drilling in Dosquebradas is complete. Acquisition activities are also underway for other excellent gold targets as defined by previous soil and rock sampling.

Cesar Lopez, President and CEO of Seafield, stated that "I am very pleased with this new resource in Miraflores as it represents a significant increase with respect to the previously reported resource and is an important step in the development of the project. It also provides an excellent basis for Seafield to commission further studies on the project, which will be incorporated into a scoping level study to be initiated this year."

Qualified Person - Scott Wilson of Scott E. Wilson Consulting, Inc. of Englewood, Colorado prepared the Miraflores Project resource estimates. The Company will file a NI 43-101 technical report in support of the technical information in this press release within 45 days.

Mr. Wilson is an independent qualified person as defined by National Instrument 43-101 and has prepared or reviewed the preparation of the information which forms the basis of this press release. He is a Certified Professional Geologist and member of the American Institute of Professional Geologists (CPG #10965) and a Registered Member (#4025107) of the Society of Mining and Metallurgy and Exploration, Inc., a professional association and designation recognized by the Canadian regulatory authorities. Mr. Wilson 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.

Sample Preparation, Assays, QA/QC. The Seafield core samples were split by rock saw and half of the core was sampled. Core samples were crushed and pulverized by SGS at their 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. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control. Silver and other metals were analyzed in a multiple element package by multiacid digestion and inductively coupled plasma emission spectroscopy finish (ICP).
