TALON METALS

OUR PROJECT

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.

We completed an Initial PEA on the portion of the independent resource estimate (effective February 15, 2018) for which representative metallurgical test results were available.

” High nickel grades, excellent metallurgical recoveries, exploration potential and good infrastructure are synonymous with the Tamarack North Project.  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 (“IRR”) of 28%, 39% and 48%, respectively.”

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:

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.

COMPLETE TEST PROGRAM RELATED TO THE IMPLEMENTATION OF BEST AVAILABLE TECHNOLOGIES

CURING AND STORING OF WASTE MATERIAL WHERE IT CAME FROM – UNDERGROUND

Metallurgical test work successfully separated high sulphur from low sulphur tailings.  Talon therefore commissioned a paste-backfill study, which showed that a paste backfill plant will produce a concrete mixture that will be pumped to mined out, open stopes for curing, thereby avoiding storage of high sulphur tailings above ground.  In addition, this cured, concrete platform, will serve as a stable base for the blasting of a new stope above.

DISPOSE ANY REMAINING MATERIALS IN A CO-DISPOSAL FILTERED TAILINGS FACILITY

Talon developed a method whereby the remaining, low sulphur tailings, not utilized to fill the open, mined out stopes, will be filtered, thereby recycling water for processing by the water treatment plant and re-use in the mineral processing facility. Talon also developed a method whereby the waste rock from the shaft and levels is used to construct a perimeter wall. The remaining development rock from a portion of the levels and all development rock from ramps will be co-disposed with the low sulphur tailings from the processing plant, thereby reducing surface expression by 37% compared to separate tailings and development rock, storage facilities. A drainage ditch around the perimeter wall will drain precipitation run-off to the water treatment plant for re-use in the mineral processing facility, thereby reducing overall water consumption. This facility is termed a Co-Disposal Filtered Tailings Facility (CFTF). The CFTF will be lined by a composite liner and upon closure, also encapsulated by a composite liner.

A MINIMIZED FOOTPRINT USING A SMALL SHAFT INSTEAD OF A BOX-CUT

Typically, a mineral deposit at 1,115 feet (340 meters) below surface would be accessed through a portal and decline. Talon commissioned three trade-off studies with the aim of reducing surface excavation area. By using a small (16.4 feet (5 meter)) diameter shaft, the surface excavation area was reduced by 99%.

LONG-TERM, SUSTAINABLE POWER FOR INDUSTRY

Once constructed, the CFTF will be an ideal platform for the construction of a solar garden that will produce clean energy. Rain water and snow melt run-off from the sealed, encapsulated CFTF will continue to be treated through a water treatment plant. Clean power and clean water could be a catalyst for creating diverse industries within this Designated Opportunity Zone. 

COMPLETE A NICKEL AND COBALT SULPHATE TRADE-OFF STUDY

THE NICKEL TO NICKEL IN BATTERIES VALUE CHAIN IS ILLUSTRATED BELOW

TALON IS INVESTIGATING THE PRODUCTION OF NICKEL SULPHATE AND COBALT SULPHATE  AS PART OF THE PRESENT METALLURGICAL TEST WORK PROGRAM.  

The aim of the test work is to demonstrate the technical feasibility for a proposed downstream processing of nickel concentrate at Tamarack to produce nickel sulphate and cobalt sulphate for the EV and stationary battery markets. This has the potential to add significant value to Talon:

Manufacturing of nickel sulphates and cobalt sulphates at the mine, would result in no third party smelting and refining costs

This could lead to direct sales to battery manufacturers, such as CATL, LG Chem, Samsung SDI, Panasonic (Tesla), SK Energy and others

Resulting in a  premium price for the nickel in nickel sulphate  (presently around 35%) when compared to the LME price for nickel as nickel metal
