Highland Copper Company Inc. ("Highland" or the "Company") is pleased to announce results for 61 additional diamond drill holes from the 543S chalcocite deposit at the Keweenaw copper project in the Upper Peninsula of Michigan, U.S.A.
Some of the higher grade and longer intersections in holes include the following:
- CEN413: 16.1 meters of 2.93% Cu and 2.6 g/t Ag including
- 3.5 meters of 8.40% Cu and 4.1 g/t Ag
- CEN415: 23.0 meters of 2.99% Cu and 10.1 g/t Ag including
- 3.0 meters of 10.83% Cu and 6.3 g/t Ag
- CEN432: 28.0 meters of 3.62% Cu and 0.9 g/t Ag including
- 2.6 meters of 8.11% Cu and 1.8 g/t Ag and
- and 16.3 meters of 2.13% Cu and 3.1 g/t Ag including
- 3.7 meters of 8.30% Cu and 1.8 g/t Ag
- CEN443: 29.0 meters of 2.51% Cu and 3.0 g/t Ag including
- 4.5 meters of 8.03% Cu and 6.1 g/t Ag
- CEN451: 20.5 meters of 2.25% Cu and 2.1 g/t Ag including
- 3.0 meters of 5.38% Cu and 1.7 g/t Ag
- CEN458: 26.1 meters of 1.62% Cu and 3.7 g/t Ag including
- 4.5 meters of 8.03% Cu and 6.6 g/t Ag
Results for composite assay intersections in all 61 holes are shown on the attached table (http://media3.marketwire.com/docs/hcopper_table.pdf). Sampling of visually-identified high grade copper intersections is on minimum 0.5 meter intervals adjusted for the geology. Individual high grade samples tend to cluster in continuous zones within broader envelopes of lower grade material. Contacts with adjacent unmineralized wall rocks may be sharp or gradational. Several holes reported in this release that lack significant mineralization are edge holes along the east side of the deposit where earlier drilling had not completely limited the mineralization. The attached cross section is located on the eastern portion of the 543S deposit (http://media3.marketwire.com/docs/hcopper%202.pdf).
"We are very pleased with the results," noted Ross R. Grunwald, PhD, Vice president of Exploration for Highland. "The pattern of high grade zones within longer intersections of lower grade copper mineralization is similar to what we have reported in previous releases indicating a consistent style of mineralization throughout the deposit. This provides confidence that a reliable geological model may be developed to support a resource estimate. The eastern and western limits of the mineralization appear to be offset by fault structures, offering significant exploration potential in the vicinity of the known 543S deposit."
"The Company has delivered the 543S database to independent consultants and a resource estimate in compliance with Canadian National Instrument 43-101 ("NI 43-101") has been initiated."
