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,
Quinchia, 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 P80 of 106mm, 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.

Seafield's Miraflores Deposit is situated in the Company's 100%-owned,
6,757-hectare, Quinchia 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.
