Mining News: News Nuggets: Constantine resumes drilling at Palmer

Constantine Metal Resources Ltd. June 3 reported that field crews have mobilized for the start of its 2015 drill program at the Palmer copper-zinc-silver-gold in Southeast Alaska. Roughly 6,000 meters of drilling is planned for this US$5 million program funded by partner Dowa Metals & Mining Co. Ltd. Drilling will focus on resource growth, with holes targeting lower elevations of the recently updated inferred mineral resource of 8.1 million metric tons grading 1.41 percent copper, 5.25 percent zinc, 0.32 grams per metric ton gold and 31.7 g/t silver. Constantine reports that the thickest part of the deposit is located at the current down-dip limit of the South Wall zone. The thickening trend of the deposit in this direction, combined with mineral zoning and borehole geophysical data, support the potential for a copper-rich core zone within the Lower offset target, located below the Kudo fault. This target, and extensions of the thick South Wall electromagnetic plate resource, represents the priority target areas for the 2015 drill program. Other work planned for the 2015 season includes borehole geophysical surveys, and environmental and geotechnical studies. Topographic relief at the project provides opportunity to drill target areas from surface with shorter length holes. Drill-hole length to reach the planned 2015 targets ranges from 400 to 800 meters, with the lower offset target roughly at the elevation of valley bottom. Drills for the 2015 program are being mobilized from a new road and laydown yard constructed in 2014.
