Seafield Expands High Grade Gold-Copper-Molybdenum Potential at Tesorito

TORONTO, ONTARIO--(Marketwired - Feb. 11, 2014) - Seafield Resources Ltd. ("Seafield" or "the Company") (TSX VENTURE:SFF) is pleased to announce the results of its recent evaluation of all exploration data acquired to date in the Tesorito area at its Quinchía Gold Project, Department of Risaralda, Colombia. Although most of the Company's focus over the last two years has been on advancing the Miraflores gold deposit towards a production decision, ongoing exploration elsewhere on the Company's large landholdings within the extensive gold-copper-molybdenum porphyry system at Quinchía, is confirming that the Tesorito area is a significant new gold-copper-molybdenum mineralized zone worthy of its own focused exploration program.

Highlights

• Hole TS-DH-02, drilled in 2013, intersected significant values of copper and molybdenum at the bottom of the hole with 0.22% Cu and 86 ppm Mo over 35 m, including 2.63% Cu over 0.7 m associated with chalcopyrite, magnetite, pyrite, molybdenite and bornite mineralization. This mineralization is in close proximity to an untested high chargeability IP anomaly making it an excellent target for further drill testing to explore for possible high-grade Cu-Mo mineralization at depth;
  
  
• The highest values in a recent trench sampling program carried out at Tesorito returned 3.18 g/t Au over 10 m, including 9.04 g/t Au over 2 m. This chip channel sample may have vertical correlation with the intersection 150 m below in hole TS-DH-02 with 29.3 m at 1.9 g/t Au, 1.0 g/t Ag and 0.12 % Cu (From 136.75 m to 166.05 m);
  
  
• Final hole in the 2013 drill program, TS-DH-03, drilled to test the SW extension of the target area, intersected similar Au-Cu mineralization to the two earlier holes including 0.58 g/t Au and 0.075 % Cu over 104.5 m.
  
  

Geology and Mineralization

The initial exploration at Tesorito in 2012 and 2013 included systematic geological mapping, rock and soil sampling, followed by trenching within the area of anomalous Au and Cu in soils. In addition, an induced polarization ("IP") geophysical survey was carried out over part of the target area (see press release dated September 27, 2012).

The Tesorito area is underlain mainly by fine to coarse grained, intrusive porphyritic rocks of granodioritic to dioritic composition, which intrude basaltic rocks of the Barroso Formation of Cretaceous age and Tertiary sandstones and mudstones of the Amaga formation (Figures 1 and 2). The intrusives show variable intensities of hydrothermal alteration, including potassic alteration overprinted by quartz-sericite and sericite-chlorite alteration. NNE, NNW and NW faulting controls the intrusive emplacement and mineralization, including faulting of contacts between the rock units. The depth of sulphide oxidation observed in the first two holes is approximately 20 m.
