Seafield Drills 200 Metres Grading 0.98 g/t Gold, 0.09% Cu at Dosquebradas, Quinchia Gold Project, Colombia
TORONTO, ONTARIO -- (Marketwire) -- 03/07/11 -- Seafield Resources Ltd. ('Seafield' or the 'Company') (TSX VENTURE: SFF) is continuing its exploration program on its Quinchia gold project in the Department of Risaralda, Colombia. In the Dosquebradas area, some 3 kilometres northwest of the Miraflores gold deposit, the current diamond drill program is testing the gold-in-soil anomaly which defines the northern extension of the Dosquebradas porphyry on Seafield's property.
Highlight:
- Hole QDQ-DH-02 was drilled at -50 degrees westward to test the extension of the gold mineralization outlined in the trench reported in the Company press release of December 8, 2010. The hole intersected 511.5 metres grading 0.58 g/t Au, 0.05% Cu including 199.9 metres grading 0.98 g/t Au, 0.09% Cu from 122 metres to 322 metres, and terminated in mineralization.
The Dosquebradas target 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. Anomalous copper and molybdenum values in soils also define the target area. To date a total of 3,497 metres have been drilled in nine holes out of a total of 11 holes planned for this phase of 5,000 metres. The program is designed to identify and delineate the gold mineralization associated with the Dosquebradas diorite porphyry intrusion. Assay data have been received for the first three holes of the program and the significant results are listed in the table below.

Note: length-weighted intervals calculated using a cut-off grade of 0.1 g/t.
Significant intervals with an average grade above 0.3 g/t Au are listed.
Grades are un-capped.
The three holes were drilled from the same platform with different azimuths as shown on the map below.

Hole QDQ-DH-01 was drilled to the northeast at an inclination of -50 degrees and intersected alternating diorites and basalt wall rock both with potassic alteration and a stockwork of quartz-magnetite veinlets. Higher grade gold intersections occur in fault breccias. The hole defines the eastern contact of mineralized diorite with basalt at 268.8 m downhole.
Hole QDQ-DH-02 was drilled to the west at an inclination of -50 degrees and intersected quartz diorites, quartz diorite breccias and basalts with potassic alteration and quartz-magnetite stockwork veinlets throughout the whole length of the hole, with a weak overprint of intermediate argillic to phyllic alteration. The hole ended in mineralization at 511.5 m depth. 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 metres and 0.90 g/t Au, 0.10 % Cu over 36 metres. Hole DQ-DD-3 drilled at -60 degrees returned grades of 0.63 g/t Au over 90.0 metres and 1.67 g/t Au over 39.5 metres.
Hole QDQ-DH-03 was drilled to the east at an inclination of -50 degrees outwards from the soil anomaly and intersected basalt country rocks with weaker alteration and low gold values up to 0.75 g/t in individual samples in the top 105 m but with no significant intervals. This hole was drilled to define the eastern limit of the mineralization.
Seafield President Anthony Roodenburg commented: 'These results from Dosquebradas are very encouraging and they confirm the existence of a potentially significant second deposit on our Quinchia project.'

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. Copper was analyzed as part of a multielement package 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.
