Seafield Resources Ltd. Commences Drilling at Miraflores Project, Quinchia, Colombia-Launches New Website

TORONTO, ONTARIO -- (Marketwire - June 28, 2010) - Seafield Resources Ltd. (TSX VENTURE: SFF) (the "Company") is pleased to announce that drilling has commenced on its Miraflores project near Quinchia in the Department of Risaralda, Colombia. The company has signed a contract with Bradley Colombia SAS to carry out an initial program of an estimated 3,500 metres of diamond drilling in 11 holes.

The Miraflores deposit currently contains an inferred mineral resource of 18.6 million tonnes grading 1.3 g/t gold at a cut-off grade of 0.5 g/t Au for a total of 776,000 ounces of gold. The mineral resource estimate is based on 3,624 metres of drilling in ten diamond drill holes and 154 underground samples.

The Company recently filed the NI 43-101 technical report on the resource estimate for its Miraflores Project in Colombia (the "Technical Report"), announced in its news release dated April 20, 2010. The Technical Report has been filed on SEDAR and includes the Miraflores grade/tonne chart for the deposit which is reproduced below.

Cut-off Grade Au g/t 	Tonnes ('000s) 	Grade Gold g/t 	Ounces Gold
0.2 	53,277 	0.654 	1,121,042
0.3 	35,042 	0.867 	976,550
0.4 	24,396 	1.095 	859,230
0.5 	18,650 	1.295 	776,373
0.6 	14,363 	1.518 	700,871
0.7 	11,316 	1.754 	638,255
0.8 	9,055 	2.000 	583,060

The Miraflores deposit is a magmatic hydrothermal porphyry breccia pipe related to the cluster of mineralized late Miocene porphyry intrusives which occur in the Quinchia district.

Ian Park, President of Minera Seafield SAS, stated "The Miraflores deposit to date has shown excellent grades and continuity. The resource is robust and holds together at various cut-off grades. The purpose of the current drill program is to both expand the resource and convert some of the inferred resources to measured and indicated resources. In addition, Seafield continues to explore a number of similar targets in the district."

Seafield is currently conducting detailed geological mapping and geochemical soil sampling over its Dos Quebradas porphyry target where two reconnaissance drill holes completed by an earlier operator reported significant intersections and grades:

Drill Hole No. 	From (m) 	To (m) 	Intersection Length (m) 	Gold Grade (g/t) 	Copper Grade (%)
DDH 2 	158 	226 	68 	0.62 	0.07
DDH 2 	232 	268 	36 	0.90 	0.11
DDH 3 	140 	230 	90 	0.63 	0.07
DDH 3 	230 	269.5 	39.5 	1.67 	0.17

The Dos Quebradas porphyry lies approximately 3 km to the northwest of the Miraflores deposit. In addition, geochemical and aeromagnetic survey data indicate the potential for an extension of the favourable porphyry host for several kilometres to the northeast. Drilling is planned on this new exploration target, following completion of the current mapping and soil/rock sampling program.

Seafield Resources will initiate further exploration over the remainder of almost 67 km2 of concession contracts, concession contracts proposals and optioned properties also within the next several months. These porphyry targets have been identified by airborne magnetic signatures and regional geochemical anomalies.

Sample Preparation, Assays, QA/QC. The Miraflores samples were prepared by ALS Chemex at a sample preparation facility in Bogota, Colombia, and were assayed at their laboratory in Lima, Peru. Gold was assayed by fire assay with atomic absorption spectrophotometer ("AAS") or gravimetric finish. Silver was assayed by four acid digestion and AAS finish. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control.
