Highland Resources intersects 20.5 meters of 2.24% Cu at the Keweenaw copper project, Michigan, USA
VANCOUVER, BRITISH COLUMBIA–(Marketwire – Oct. 3, 2012) – Highland Resources Inc. (TSX VENTURE:HI) (“Highland” or the “Company”) is pleased to announce results from the first 17 diamond drill holes for which all assays have been received from the Keweenaw Copper Project in northern Michigan. Some of the longer intersections include:
- Hole CEN 302: 20.5 meters of 2.24% Cu
- Hole CEN 308: 9.0 meters of 2.10% Cu
- Hole CEN 309: 12.0 meters of 3.24% Cu
- Hole CEN 312: 13.1 meters of 3.02% Cu
- Hole CEN 313: 10.4 meters of 1.77% Cu
- Hole CEN 331: 17.0 meters of 2.07% Cu
Assay results are summarized in Table 1 below and drill hole locations are on Figure 1. The objective of the exploration program initiated in July is to confirm in compliance with NI 43-101 the historical resource of the 543S deposit originally discovered in the early 1970s. Lens-like zones of mineralization consist mostly of primary chalcocite in altered basalt flow top breccias accompanied by small amounts of native copper and native silver (see cross section 200E in Figure 2). Traces of other sulfide minerals are also present. Mineralization comes to the bedrock surface and is covered by 3 to 30 meters of glacial deposits.
“The alteration and mineralization intersected by Highland are identical to the available historic core and we are encouraged that the historic resource estimates from the 543S deposit may be duplicated by the current drill program” noted Dr. Ross R. Grunwald, Vice president – Exploration for Highland. “Four drills are operating at the project and the initial plan is to complete roughly 20,000 meters in 100 holes by mid-late October. Upon completion of the planned program we will evaluate the need for interspaced holes at 543S and will consider moving drills to several of the numerous additional chalcocite prospects in this area.”
The 2012 drill holes are within an area of 101 historic diamond drill holes called the 543S sulphide deposit, a zone of chalcocite mineralization that was explored from 1973-1977 and briefly in the mid-nineties. The 543S deposit contains a historic resource estimate of 4.5 million short tons averaging 2.27% Cu at a 0.75% Cu cutoff grade as described in a Technical Report by Behre Dolbear & Company, Ltd. titled “Centennial and Kingston Native Copper, 543S, and Other Copper Sulfide Properties, Houghton and Keweenaw Counties, Michigan, USA” dated September 29, 2011. The Company has not completed the work necessary to classify the historical estimate mentioned above as current mineral resources. The Company is not treating the historical estimate as current mineral resources as defined in NI 43-101 and the historical estimate should not be relied upon. Highland’s objective is to complete approximately 100 diamond drill holes to confirm the size and grade of the non-compliant 543S historic resource estimate. Resource modeling will begin in early 2013 if justified. The historical resource estimate is contained in six separate lenses averaging 5.0 meters (16.5 ft.) true thickness that dip about 40° to the north.

Drilling, Sampling, Assaying, and QAQC
The 2012 drill holes are on cross sections spaced at 30 meter intervals between the historic 60 meter grid lines at the 543S deposit. All holes reported on Table 1 except CEN 306 and CEN 307 are inclined to the south along section lines shown on Figure 1. Inclinations are selected to approximate a true width of the mineralized lenses based on regional information on the dips of the lava flows. Holes CEN306 and CEN 307 are inclined to the west and the intersections reported in Table 1 for CEN307 may be 5-10 percent greater than true widths.
All technical information for the 543S exploration program is collected under a formal quality assurance and quality control (QAQC) program. Samples are taken under the direction of qualified geologists and stored in sealed bags. Samples are then placed in sealed containers and delivered via courier or common carrier to Accurassay Labs, a certified analytical facility in Thunder Bay, Ontario, Canada for analysis. Copper and silver contents are determined using a four acid digestion procedure.
The technical information contained in this release has been reviewed and approved by Ross R. Grunwald, PhD., Vice president – Exploration for the Company. Dr. Grunwald is a qualified person as defined in NI 43-101.
