Seafield reports updated metallurgical results and high gold recovery rates at Miraflores, Colombia

Monday, Feb 18, 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, 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.

"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.
