Vancouver-based Gold Hawk Resources Inc. announced that the company's U.S. subsidiary has contracted Major Drilling for a surface diamond drill program at its Oracle Ridge Copper Mine [right, credit, Gold Hawk Resources] in the Santa Catalina Mountains north of Tucson.
The company press release says "the phase one surface drill program is for an initial 15,000 feet designed to validate the existing drill hole data."
"Gold Hawk is in possession of the historic data base consisting of 534 drill holes totaling more than 163,000 feet of drilling. The available historic drill core samples are in good condition and stored on site and are in the process of being catalogued, logged and assayed as part of the study to bring the project to NI 43-101 standards."
The company's August 20, 2010 Technical Report, Review of the Oracle Ridge Mine Project, is available on SEDAR and on the company's website Properties page - (http://www.goldhawkresources.com/en/properties/oracle-ridge.php).
