The Tamarack Intrusive Complex (TIC) is a 2002 original Kennecott Exploration Company (a subsidiary of the Rio Tinto Group) discovery with approximately 124,000 meters drilled to date and a land package comprising 31,000 acres. Nine exploration target areas over a strike length of 18 kilometers (11.2 miles) have intercepted sulphide mineralization, making the TIC comparable in strike length to some of the world's most prolific nickel producers.

The TIC is located 85 km west of Duluth, Minnesota.
At the Talon/Kennecott core-shed you will be welcomed by professional geologists who will be happy to take you on a fascinating tour of the different rock types, being samples from the 124,000 meters of drilling.
Our objective is to take the project through to a pre-feasibility study but before we can do that we need to:
COMPLETE METALLURGICAL TESTING TO INCLUDE THE FULL RESOURCE ESTIMATE IN THE NEXT ITERATION OF THE PEA MINE PLAN
The majority of the inferred mineral resource estimate tonnage in the upper Semi-Massive Sulphide Unit (SMSU) and all of the tonnage in the 138 Zone have been excluded from this Initial PEA as metallurgical testing is still in progress. One objective of the current metallurgical test program is to expand metallurgical testing to include the total mineral resource estimate. A second objective is to simplify the flowsheet and reagent regime, thus reducing the capital and operating expenses for a given plant throughput.
In a world of ever decreasing nickel grades and deeper nickel mines, the Tamarack North Project Initial PEA demonstrates robust economics with pessimistic ($6.75/lb Ni), base case ($8/lb Ni) and incentive pricing ($9.50/lb Ni) after-tax Internal Rates of Return of 28%, 39% and 48%, respectively.

EXPLORE POSSIBLE MSU EXTENSIONS BELOW THE 138 ZONE AND POSSIBLE MSU ACCUMULATION IN THE 164 ZONE AND CGO BEND
In working with Kennecott over the last number of years, we have refined an effective combination of geological and geophysical methods, both surface and downhole, that have successfully been used to substantially increase the Massive Sulphide Unit (MSU) resource at Tamarack. These methods will be repeated outside of the Tamarack Zone to effectively design drill hole targets for intercepting MSU, which, if successful, will have a profound impact on any future mine plan. More specifically:
LONG SECTION LOOKING FROM THE EAST (LOOKING TO THE WEST)
PLAN VIEW (LOOKING FROM THE TOP)
CONSIDER THE POSSIBLE IMPACT OF FUTURE EXPLORATION POTENTIAL TO THE SOUTH OF THE 164 ZONE AND TO THE NORTH OF THE CGO BEND
The Tamarack and 138 Zones, where the NI 43-101 resource is located, is the first out of nine qualified exploration targets that require further investigation along the 11.6 mile (18 km) Tamarack Intrusive Complex (TIC).
“The zone of entry of the FGO into the Bowl becomes highly prospective for sulphides that have settled out of the FGO magma, as its rate of intrusion likely slowed on entering into the wider chamber. The Eastern Deeps ore body at Voisey’s Bay occurs precisely along the zone within which a feeder dyke enters the upper chamber” said Dr. Anthony J. Naldrett , University Professor Emeritus, University of Toronto and author of the book Magmatic Sulphide Deposits, Geology, Geochemistry and Exploration (Director, Talon). Click here to learn more.
