Millrock Resources Inc. ("Millrock" or "the Company") recently completed a seismic geophysical survey and drilling of a single reverse circulation borehole at its Monsoon copper project in southeast Arizona. The survey results and the drill hole indicate that it is unlikely that a large porphyry copper deposit exists within 500 m of surface.
The project was the subject of an option agreement with FQM (Akubra) Inc, formerly Inmet Mining Corporation, a wholly owned subsidiary of First Quantum Minerals Ltd. ("FQML") whereby FQML may have earned a 70% joint venture interest. FQML has advised Millrock that it will withdraw from the option agreement. Millrock believes there is potential for discovery of a porphyry copper deposit at greater depth and intends to seek a new funding partner to further test the targets developed.
Prior to the recent exploration phase Millrock had carried out property-wide biogeochemical sampling, soil sampling, water well sampling, and airborne ZTEM and magnetic surveys. The work was designed to search for buried porphyry copper deposits along the projected trend of the Safford copper deposits in Laramide-aged rocks that host copper mineralization in the district.
Reprocessing and interpretation of historic seismic data had led Millrock to believe that an upthrown structural block of Laramide-aged rock may be present, and that copper mineralization may exist in the shallow subsurface. A modern 2D seismic reflection survey was carried out to confirm the historic survey in an area where Millrock had discovered polymetallic anomalies in various geochemical surveys. Two lines totaling approximately 17 km were surveyed. Two possible interpretations could be made from the seismic data. One interpretation indicated the favourable Laramide contact was at an approximate depth of 500 m below surface. Another interpretation indicated a depth of approximately 1,000 m.
A vertically-oriented 500 m reverse circulation hole was drilled as a stratigraphic test and to determine the source of the geochemical anomaly. Results of the drilling suggest that an upthrown structural block does exist in the area tested. Tertiary volcanic rock was intersected at only 100 m below surface; a much shallower level than in holes drilled by prior explorers elsewhere on the property. However, the contact with the Laramide aged rocks must lie deeper than 500 m; most likely at an approximate depth of 1,000 m.
