Seafield Reports Drilling Results from the Porphyry-Style Dosquebradas Target at Its Quinchia Gold District Project, Colombia

TORONTO, ONTARIO--(Marketwire - July 25, 2011) - Seafield Resources Ltd. (TSX VENTURE:SFF) ("Seafield" or the "Company") is pleased to announce the drill results from the Dosquebradas area as part of its ongoing exploration program at its Quinchia gold project in the Department of Risaralda, Colombia.

The Dosquebradas area is 3 kilometres northwest of the Miraflores gold deposit, where Seafield has previously announced 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 (see press release dated May 26, 2011).

The current diamond drill program at Dosquebradas was planned to test a gold-in-soil anomaly in an area where in 2006, AngloGold Ashanti drilled a total of 587 meters in two holes. Seafield's goal for the Phase I Drilling just completed was to expand on these AngoGold Ashanti holes and obtain information to understand the geology and nature of the mineralization.

Seafield President, Cesar Lopez, stated, "Seafield was successful in accomplishing the goal of the Phase I drilling at Dosquebradas, as we have now defined where the strong mineralization is and the direction of its extension. Now that we understand more about the geology, we will implement the Phase II drilling program which will follow on the mineralized areas that returned greater than 0.3 g/t intercepts, for the purpose of developing at least an inferred mineral resource at Dosquebradas."

To date a total of 5,648 metres have been drilled in thirteen holes (nearly double the amount that was originally announced in the Company's press release dated December 8, 2010). The program was designed to trace northwards and delineate the gold mineralization associated with the Dosquebradas quartz diorite porphyry intrusion. Assay data have now been received for all thirteen holes of the program and the significant results are listed in the table below.

The drill hole pattern was laid out across the Dosquebradas area to test the general district trend of porphyry intrusive rocks to the north as well as associated north-trending structures and the coincident gold in soil anomaly (see map above).

The best gold mineralization to date at Dosquebradas is associated with an Early Diorite porphyry and associated intrusive breccias shown on the above map. The grades above 0.3 g/t gold are concentrated in a zone approximately 250 meters wide (E-W) and greater than 300 meters long (N-S). The zone is open at depth and is interpreted to plunge to the north. This zone was intersected by holes QDQ-DH-02, with 511.5 m at 0.58 g/t Au including 199.9 m at 0.98 g/t Au (reported in press release of March 7, 2011) and QDQ-DH-13 with 60.4 m at 0.63 g/t Au. This is part of a larger porphyry system at least 600 meters long (N-S) by 600 meters wide (E-W). Other drill holes intersected lower grades of gold mineralization associated with inter-mineral and late diorite porphyries and breccias and basalt wall rock.

Trench sampling of the Early Diorite porphyry by Seafield returned 1.75 g/t Au over 94 m (see press release of December 8, 2010).

AngloGold Ashanti, a previous operator, drilled two shorter holes in 2006 on the same section as QDQ-DH-02. Hole DQ-DD-2 returned 0.62 g/t Au, 0.07% Cu over 68 meters and 0.90 g/t Au, 0.10 % Cu over 36 meters. Hole DQ-DD-3 drilled at -60° returned grades of 0.63 g/t Au over 90.0 meters and 1.67 g/t Au over 39.5 meters.

Seafield has started a second diamond drill program of 5,635 meters in 12 holes over an area of approximately 300m x 200m with two drill rigs in order to better define the gold mineralization in the Early Diorite porphyry and be able to make a mineral resource estimate.

Sample Collection, Preparation, Analyses and QA-QC

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. Multielements were analyzed by inductively coupled plasma mass spectroscopy (ICP-MS) following multiacid digestion. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control.
