Eagle Hill Exploration Corp. (TSXV:EAG,OTCQX:EHECF) announced that further metallurgical testing shows that gold recovery at its Windfall Lake project could be as high as 95.7 percent using a standard flotation and cyanide leaching process.
As quoted in the press release:
In 2013, Eagle Hill used two 75-kg samples from two sectors of the deposit to complete metallurgical testing. In October 2014 Eagle Hill performed cyanide leaching on the flotation test reject from the 2013 testwork to determine the amount of recoverable gold still present in the material. This new testing, completed by ALS Minerals, Metallurgy Division in Kamloops, Canada, shows that gold recovery can be increased by 4% when flotation rejects are ground to less than 70 μm and processed with cyanide leaching. As a result, Eagle Hill will use a 95.7% gold recovery factor in the Preliminary Economic Assessment, an increase from the 91.7% recovery factor used in the National Instrument 43-101 technical report for the project prepared by SRK Consulting (Canada), Inc. dated April 17, 2014.
