Seafield Resources Ltd. reported 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. located in Richmond, BC, Canada. 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 earlier PEA study 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.

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. 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.
