Talon Metals Announces Initial NI 43-101 Technical Report for the Tamarack South Project
- The drilling at the Tamarack South Project has shown that the magmatic layering of the FGO (Fine Grain Olivine) intrusive (original sulphide bearing peridotite) is consistent with the magmatic layering at the Tamarack North Project.
- Massive sulphide intersections proximal to the FGO footwall contact, similar to the Tamarack North Project, have been encountered in three of seven drill holes spaced 300 m and 200 m apart within the Neck Zone (see Figure 3).
- Five of seven holes within the Neck Zone have shown between 15.2 m and up to 520.8 m of trace to blebby sulphides within the FGO intrusive (see Figure 3).
Only limited drilling (27 holes) has been completed over a 7,400 acre (30 km2) area comprising the Tamarack South Project.
"With respect to the Tamarack South Project, 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.
Road Town, British Virgin Islands--(Newsfile Corp. - November 29, 2018) - Talon Metals Corp. (TSX:TLO) ("Talon" or the "Company") is pleased to announce the results of the National Instrument 43-101 technical report (the "Technical Report") in respect to the Tamarack South Nickel-Copper-Cobalt (the "Tamarack South Project") located in Minnesota, USA.
Tamarack South Technical Report Summary
Located within Aitkin and Carlton Counties, Minnesota, USA (see Figure 1) the Tamarack South Project represents the southern part of the extensive Tamarack Intrusive Complex (the "TIC"), an ultramafic to mafic intrusive complex that hosts Ni-Cu sulphide mineralization with associated Co, Pt, Pd (PGEs) and Au (see Figure 2). The Tamarack South Project contains extensive portions of the TIC intrusion, however, to date, most of the exploration and activity has been focused and reported for the Tamarack North Project. The limited drilling that has been conducted has demonstrated the future potential at the Tamarack South Project.
The geometry of the TIC, as outlined by a well-defined aeromagnetic anomaly, consists of a curved, elongated intrusion striking NS to SE over 18 km and is related to the early evolution of the approximately 1.1 Ga Midcontinent Rift (MCR).
To date, exploration by Kennecott Exploration Company ("Kennecott") has included a wide range of geophysical surveys including: airborne magnetic and electromagnetic (EM-MEGATEM and AeroTEM), ground magnetic, surface EM and MT, IP, gravity, seismic, MALM and DHEM. Kennecott has conducted limited reconnaissance style drilling at the Tamarack South Project since 2002. This drilling is comprised of 27 diamond drill holes totalling 17,314 m with drill holes between 97.5 m and over 1,230 m depth. The Tamarack South Project has been divided into the Neck and Bowl Zones, reflecting analogous shapes of the intrusive geology (see Figure 2).
The Tamarack South Project drill hole geochemical data indicates that the FGO intrusive is consistent with the mineral bearing FGO found within the Tamarack North Project. As well, the magmatic layering found in the Tamarack North Project appears to continue into the Tamarack South Project (see Figure 2). Limited exploration drilling in the Bowl portion of the intrusion has also confirmed the presence of Norite and Dunite layering.

Currently, at the Tamarack South Project there are two prospective exploration areas at:
1) The Neck Zone, which has demonstrated widespread, anomalous, low grade Ni-Cu-Co sulphide mineralization at depth and also provided three massive sulphide intersections within the lower FGO layers (see Figure 3) (See Annex A for drill intercept details). Evidently, a result of the winnowing out of droplets of dense sulphide liquid from an overlying flow of sulphide-bearing silicate magma, the conceptual analogous model would be typical of a Norilsk style deposit (i.e. Talnakh).
2) The drill results from the Neck Zone have also established that the FGO plunges to the south and potentially underlies the Bowl as a possible feeder (see Figure 2). This presents the potential for future exploration targeting based on Talon's current conceptual model proposed by Professor Naldrett (see Figure 4) and analogous to his previous work at Voisey's Bay (Eastern Deeps) (see Figure 5).

The Tamarack South Project, given its size and favourable geologic environment, has the potential for hosting Ni-Cu-Co massive sulphide deposit(s). Talon intends to further investigate these prospective areas using ground geophysics as a means of leveraging low cost high value targeting information prior to any drilling program.
Quality Assurance, Quality Control and Qualified Persons
The Tamarack South Project has a consistent QA/QC program of analysing duplicates of pulps, coarse rejects, and core, as well as the routine insertion of quality control reference standards and blanks.

All samples were analysed by ALS Minerals. Nickel, copper, and cobalt grades were first analysed by a 4 acid digestion and ICP AES (ME-MS61).Grades reporting greater than 0.25% Ni and/or 0.1% Cu, using ME-MS61, trigger a sodium peroxide fusion with ICP-AES finish (ICP81). Platinum, palladium and gold are initially analyzed by a 50g fire assay with an ICP-MS finish (PGM-MS24). Any samples reporting >1g/t Pt or Pd trigger an over-limit analysis by ICP-AES finish (PGM-ICP27) and any samples reporting >1g/t Au trigger an over-limit analysis by AAS (Au-AA26).
