Seafield Drills 449 Metres Grading 1.29 g/t Gold at Miraflores, Quinchia Gold Project, Colombia

TORONTO, ONTARIO--(Marketwire - Dec. 2, 2010) - Seafield Resources Ltd. (TSX VENTURE:SFF) ("Seafield" or the "Company") is pleased to announce assay results from the first three drill holes at its Miraflores property at the Quinchia Gold project, Risaralda, Colombia. The Quinchia project contains a number of porphyry and porphyry breccia open pit targets including the breccia style deposit at Miraflores. 

  • Hole QM DH-03 was drilled from the NE contact to the SW contact through the centre of the Miraflores porphyry breccia pipe body and intersected 449 metres grading 1.29 g/t Au, including 23.95 metres grading 9.18 g/t Au

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. Using a cut-off of 0.3 g/t Au, the inferred resources expand to 976,550 ounces gold. The mineral resource estimate is based on 3,624 metres of drilling in ten diamond drill holes carried out in 2006 and 2007, and 154 underground samples. The current diamond drill program was designed to expand the resources and better delineate the porphyry intrusion breccia body which hosts the gold mineralization. Core logging from several of the current holes shows that the breccia body is more extensive at depth than was inferred from previous drilling. A total of 4,132 metres were drilled in 12 holes during the recently completed program.

Of the first three holes reported here, holes QM DH-01 and QM DH-02 were drilled at an inclination of -60° to define the projected margin of the breccia body whereas QM DH-03 was drilled at an inclination of -50° to a depth of 596 metres from the NE contact to the SW contact through the centre of the breccia body. (See map.) Significant assay results from these first three holes are as follows:

Hole From (m) To (m) Interval Gold (g/t) Comments
QM DH-01 70.9 82.9 12.2 0.66 SE Margin
  139.8 218.0 78.2 0.48  
  264.5 270.5 6.0 0.59  
  425.5 437.0 11.5 0.45  
QM DH-02 59.2 93.2 34.0 0.80 SE Margin
QM DH-03 53.1 502.1 449.0 1.29 1.03 g/t cut
including 231.8 241.8 10.0 2.87  
including 282.55 306.5 23.95 9.18 4.67 g/t cut
Note: Hole QM DH-03 contains some samples with bonanza grades of up to 71.04 g/t Au over 2.0 m. The length weighted average grades in the table are uncut, and where appropriate, grades are also shown cut to 20 g/t Au.

Geologically the Miraflores breccia body consists of a number of variably mineralized, separate, intrusive porphyry breccia phases with the better gold mineralization being associated with a later clean breccia phase which is cemented by vuggy quartz, carbonate and epidote associated with pyrite, sphalerite, chalcopyrite and galena with local visible gold.

Seafield President Anthony Roodenburg stated: "With the best hole ever drilled on the Miraflores project, we are very optimistic that we will see an increase in the inferred resource, and our continuing exploration and drilling on the other porphyry targets on our large property will allow us to further increase resources in the district."

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. Blank, standard and duplicate samples were routinely inserted for quality assurance and quality control.
