Blackwolf holds 100% interest in the advanced stage Niblack Project on Prince of Whales Island located in southeast Alaska, less than 50kms from the town of Ketchikan, AK and 100kms from Stewart, BC. (see Figure 1)
The Niblack Project is endowed with volcanogenic massive sulphide (VMS) mineralization including the Lookout and Trio deposits which host 43-101 compliant resources of copper, gold, silver, and zinc.
Niblack hosts six known VMS zones (the Lookout and Trio deposits and the Dama, Lindsy, Mammoth, and historic Niblack Mine site) within a 6,200-acre property that includes 250 acres of patented lands.
The property is located near tidewater, enjoys year-round marine and floatplane access, and is well-served by existing site infrastructure. Key project infrastructure at the Niblack Project includes: a road network, over one kilometre of underground workings, a water treatment plant and discharge system, a dock and barge plus a core logging facility, power generation, and ancillary buildings.
Since 2009, drilling has been successful at significantly increasing resource tonnage at Niblack Project - the Indicated resource has grown from 2.6 million tonnes to 5.6 million tonnes and the Inferred resource has grown from 1.7 million tonnes to 3.4 million tonnes (see Figure 2 below).
At a US$50 net smelter return cutoff, the November 2011 estimate comprises:
- 5.6 million tonnes in the Indicated category grading 0.95% copper, 1.75 g/t gold, 1.73% zinc, 29.52 g/t silver; and
- 3.4 million tonnes in the Inferred category grading 0.81% copper, 1.32 g/t gold, 1.29% zinc, 20.10 g/t silver.
Within the Indicated resources in the Lookout deposit there is a continuous higher grade zone which, at a US$150 NSR cut off, comprises 1.12 million tonnes grading 1.71% copper, 3.21 g/t gold, 3.83% zinc, 62.68 g/t silver.
Modern metallurgical studies have yielded good recoveries through traditional methods and government agencies are helping to facilitate resource development in the region.
All of the known six zones on the Niblack project remain open and are candidates for further resource expansion.
In December of 2020, an 1,800 metre drill program at the historic Niblack Mine site confirmed a new geological interpretation of the deposit, thereby opening up the project for mineralization to be discovered on new areas (see the purple horizon in Figure 3 below).
