Seafield Resources Ltd. (TSX VENTURE:SFF) is continuing its exploration program on its 6,757 hectare Quinchia gold project in the Department of Risaralda, Colombia.
Following completion of the drill program at the Miraflores gold-bearing breccia body, the diamond drill has now been moved about three kilometres to the northwest, to the Dosquebradas area to extend the gold mineralized porphyry discovered in 2006.
The gold-in-soil anomaly which defines the northern extension of the Dosquebradas porphyry on Seafield's property has an area of about 700 metres by 550 metres as defined by soil samples above 50 ppb Au (0.05 g/t Au). Values in soils are as high as 0.58 g/t Au.
Trenching in one location at the southern end of the anomaly has exposed sheeted quartz veinlets crosscutting quartz diorite porphyry and basalt wall-rock and containing iron-rich weathering products after magnetite or sulfides. Continuous channel samples, each two metres in length, collected from the trench returned the following widths and gold grades:
This trench extends east-west and is close to the surface trace of a hole drilled into the Dosquebradas porphyry intrusion in 2006 by AngloGold Ashanti, a previous operator. This hole DQ-DD-3 drilled at -60°returned grades of 0.63 g/t Au over 90.0 metres and 1.67 g/t Au over 39.5 metres about 200 metres below the trench.
Plans for the Dosquebradas drill program are to drill up to 3,000 metres in 8 holes and currently a total of 1336 metres have been completed in three holes. These holes exhibit zones consisting of sheeted quartz-magnetite veinlets with minor pyrite in altered quartz diorite porphyry, breccia and basalt, similar to that found in the hole DQ-DD-3 mentioned above.

Stewart D. Redwood, Consulting Geologist to 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 sampling program. Dr. Redwood is a Fellow of the Institute of Materials, Minerals and Mining (Number 47017), a professional association and designation recognized by the Canadian regulatory authorities. Dr. Redwood verified the data disclosed in this release, including the sampling, analytical and test data underlying the information contained in this release.

Sample Collection, Preparation, Analyses and QA-QC
The trench chip samples were delivered to the SGS laboratory in Medellin for preparation 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.
