Seafield Resources Ltd. announced an updated NI 43-101 compliant resource for its Miraflores breccia deposit within the company's Quinchía Gold and Silver Project. Seafield's 6,757- hectare Quinchía Gold Project is located in the Department of Risaralda, Colombia. This update incorporates an additional 10,725.3 m of drilling for a total of 25,884.1 m used in the resource estimate.

These results will be incorporated into the updated Preliminary Economic Assessment, scheduled for completion by the end of second quarter of 2013. Highlights: The updated NI 43-101 report documents a measured and indicated resource of 1,816,000 Troy ounces (oz) of gold (Au) grading 0.78 grams per tonne Au and 3,555,000 oz of silver at 1.5 g/t Ag, contained in 72,624,000 tonnes at a cut-off grade of 0.27 g/t Au; The estimate significantly increases the geological confidence in the model by increasing the mineral resources in the measured category from 28.5 Million tonnes to 38.7 Million tonnes and by delineating a greater number of high grade veins at Miraflores. The presence of 21 veins cross cutting the breccia body was confirmed, further improving the definition of the mineralization in the breccia and adjoining basalt.

This more accurate geological model of the deposit will be used for advanced mining studies; A very robust geostatistical analysis was carried out to define estimation parameters, which resulted in a capping of higher gold grades at 45 g/t Au in the breccia and individual analysis in the veins ranging up to 24 g/t Au; The estimate has been delivered on time in accordance with the project schedule and as communicated in the "Miraflores Technical Update".
