TORONTO, ONTARIO--(Marketwire - Feb. 15, 2013) - Seafield Resources Ltd. ("Seafield" or "the Company") (TSX VENTURE:SFF) is pleased to report preliminary metallurgical test results of an extensive metallurgical development program for its gold-silver Miraflores Deposit, Quinchía, Colombia, presently underway at Inspectorate Exploration and Mining Services Ltd. ("Inspectorate"), located in Richmond, BC, Canada. This study program was designed and is being supervised by SRK Consulting in Denver ("SRK") on behalf of Seafield.

Highlights:

• All test composite samples evaluated were highly amenable to gold recovery by a process flow sheet using conventional gravity concentration followed by gold flotation from the gravity tailings;

• All test composite samples, ground to a nominal P 80 of 106 m m, contained significant amounts of coarse gold amenable to gravity concentration. Gold recoveries of 52 to 65% were obtained in gravity cleaner concentrates containing between 382 - 1,271 g/t Au;

• Gravity concentration followed by gold rougher flotation from gravity tailings resulted in gold recoveries ranging from 94 to 98%;

• The next phase of the metallurgical program will investigate process parameters required to cyanide leach the gold contained in the flotation concentrates.

"We are delighted to confirm the high gold recovery rates for all major geo-metallurgical units in the Miraflores deposit and are confident these materials can be treated efficiently by the flow sheets evaluated with the present metallurgical development program," commented Dave Prins, Seafield's Chief Operating Officer. "As this study advances, the results obtained will provide the data required for the design of a potential commercial processing facility."

Sample Characterization

Three composite samples were prepared from multiple quarter-core drill hole samples representing the major geo-metallurgical units in the mineable areas of the deposit. Based on the mining plans developed in our earlier PEA study (see press release dated, April 23, 2012) two mining operations, an open pit and an underground mine were designed. In the open pit mine, the major geo-metallurgical units were determined to be White and Green breccias with a minor contribution of Red and Grey breccias and Basalt. In the underground mine the major geo-metallurgical unit are the White breccias, with minor amounts of Green breccias. The minor geo-metallurgical units are not included in the master composite samples and will be used only for process variability studies.

For the purposes of this study, the major geo-metallurgical units of both open pit and underground mines were studied in detail. Considering that the Miraflores deposit is essentially a large mineralized breccia containing multiple high-grade veins, the samples selected to be part of the master composites consisted of long mineralized quarter core intervals of varying grades, which included vein intervals.

To prepare the composites for the open pit mine, the drill holes and intervals selected crossed the proposed minable material blocks from the PEA mining plan. Similarly, for the underground mine, the drill holes and intervals selected were within the material blocks that could be mined as indicated by the PEA mining plan.

Table 1 below, shows the characterization of these sample composites.

Metallurgical Test Results

Initial test work was conducted on the three composite samples representing the major geo-metallurgical units at a target P80 grind of 74 microns. After gravity separation, the gravity tails were subjected to rougher gold flotation using different reagent schemes. Once optimum process parameters for flotation were established, tests were conducted to evaluate gold recovery versus grind size for each master composite.

Table 2 shows the effect of grind size on gold recovery for the major geo-metallurgical units. An economic analysis will determine the optimum grind size.

Work in Progress

Future work to be completed is outlined below, with the metallurgical test work program scheduled for completion in Q2 2013:

• Completion of Master Composite Studies:
  • Mineralogical evaluations
  • Gravity concentration-rougher flotation-cleaner flotation studies
  • Locked-cycle flotation tests
  • Concentrate cyanide leaching
  • Cyanide detoxification studies
  • Sedimentation studies
  • Tailings geochemistry evaluation

• Comminution Testing (Master Composites and Variability Composites)
  • Bond ball mill work index
  • SAG Mill Comminution (SMC) tests
  • Abrasion work index

• Metallurgical testing on variability composites

Seafield's Miraflores Deposit is situated in the Company's 100%-owned, 6,757-hectare, Quinchía Gold Project. Miraflores is a low sulphidation epithermal gold deposit located in Colombia's mineral-prolific Mid-Cauca gold belt. The mineralization is located in a hydrothermal breccia pipe with free gold associated with cement materials (the matrix) and high grade structures where gold is associated with zinc, lead, copper and iron. At surface, the breccia pipe has a drill-tested diameter of 250 metres by 280 metres. The breccia pipe widens and remains open at depth with a drill-tested vertical extent of 600 metres.
