Quaterra Acquires Peg Leg Porphyry Copper Prospect in Arizona
Quaterra Resources Inc. announces the acquisition of the Peg Leg porphyry copper prospect in south-central Arizona. The primary target is a classic San Manuel-Kalamazoo type deposit with the possibility of higher copper grades associated with either a classic chalcocite blanket, or with abundant diabase as at the Ray copper deposit that is located eight miles to the north.
The Peg Leg project is in a region with the highest density of known porphyry copper deposits in the world. The company acquired approximately 11 square miles of mineral rights over the prospect by staking 247 unpatented U.S. lode claims and leasing three Arizona State prospecting permits along the western flank of the Tortilla Mountains, twenty miles east of the Poston Butte copper deposit near Florence, Arizona.
Exploration of the Peg Leg porphyry copper prospect was initiated by Exxon Minerals in the early 1980s. The program defined a large IP (chargeability high-resistivity low) geophysical anomaly that extends over an area of 10 square miles. Five core drill holes (11,726 feet) ranging in depth from 1,948 to 3,283 feet targeted a small part of the anomaly and encountered alteration and low grade copper mineralization interpreted to represent the margins of a large porphyry copper system. The holes may have stopped short of, or been drilled adjacent to, a possible “ore shell”.
The first and deepest drill hole had the best intercept with 473 feet of 547 ppm Cu from a depth of 2810 feet to the bottom of the hole. Mineralization is related to a large zone of potassic-altered quartz monzonite. The remaining four holes intercepted anomalous copper mineralization related to propylitic and outer phyllic alteration along the margins of the system. The large size of the target and the structural complexity of the area suggest that shallower oxide and/or sulfide mineralization may be present.
“We are quite excited about the potential for discovery at Peg Leg.” commented Quaterra President, Dr Thomas Patton. “The prospect has the right address and all the ingredients necessary for major porphyry copper deposit.”
Dr. Patton also announced that Quaterra has signed a consulting agreement to retain the services of James P. Vroman of Tucson, Arizona as exploration manager for the Peg Leg project. Mr. Vroman has 15 years of experience in minerals exploration including six years with Exxon Minerals where as Senior Minerals Geologist, he was responsible for planning and implementing exploration projects throughout the western United States.
Quaterra will carry out geophysical surveys at Peg Leg during 2007 in advance of a possible drilling program.
