ZINC-LEAD: Darnley Bay files technical report for Pine Point project

NORTHWEST TERRITORIES – Darnley Bay Resources of Toronto has filed an updated resource estimate for its 100% owned Pine Point zinc-lead project 42 km east of Hay River. The report is based on 15 of deposits on the property that have 43-101-compliant measured an indicated resources totaling about 28 million tonnes. Additionally, the property contains a total of 54 undeveloped deposits with historic non-compliant resources on the property.

The facilities at Pine Point in 1985.

The property was previously explored by Cominco, Westmin and Tamerlane. Cominco mined 64 million tonnes of ore grading 7.0% zinc and 3.1% lead from 52 deposits when it operated the  mine from 1964 to 1987.

Pine Point belongs to the class of carbonate hosted zinc-lead sulphide deposits known as Mississippi Valley Type deposits. Darnley Bay notes that MVT deposits are among the most important zinc and lead  sources in the world. They typically have moderate to high grades, simple metallurgy, and yield high quality concentrates.

Darnley Bay believes there are 34 additional geophysical anomalies at Pine Point that require further work, particularly on the South Trend. Large portions of the western most leases are underexplored due to their long distance from the original Pine Point concentrator. A new mill location is contemplated.
