GT Resources drills up to 0.9% Ni at Moshkinabi Intrusion, Tyko Ni - Cu Project

Mar 11, 2024

"The first drilling on the Tyko II property has returned encouraging results including up to 0.9% Ni in massive sulphide. The drill program was focused on the Moshkinabi intrusion which is the best mapped and hence understood part of the wider Faries-Moshkinabi mafic-ultramafic complex. Large parts of this intrusive complex remain untested, notably the Gionet Zone which has demonstrated strong copper and nickel soil anomalies coincident with VTEM anomalies. Plans are underway to further explore this large mafic-ultramafic complex once additional Exploration Permits are received," said Derrick Weyrauch, President and CEO. 

GT Resources Inc. is pleased to announce final results from the 2023 drill program on the Tyko II Property, which forms part of the larger Tyko Nickel-Copper Project in Ontario.


  • Represents GT's first drill testing on the Tyko II Property.
  • Massive sulphide was intercepted at the base of the Moshkinabi intrusion thereby supporting the prospectivity for additional massive sulphide mineralization at Tyko II. Drilling returned: 
    • 0.8% Ni, 0.6% Cu over 0.7 meters including 0.9% Ni, 0.6% Cu over 0.4 meters in hole TK23-141
  • Also intersected was disseminated copper-palladium-rich mineralization, within the Kejimalda Zone, which represents an additional style of mineralization and further supports the prospectivity of the area. Drilling returned:
    • 0.1% Cu, 0.33 g/t TPM ("Platinum + Palladium + Gold") over 24.3 meters including 0.23% Cu, 0.73 g/t TPM over 2.0 meters in hole TK23-142.
    • The Kejimalda Zone extends over a 3-kilometer strike length and ranges in width from a few meters up to 30 meters in width.
  • In Q4 2023, 3,028 meters were drilled in 22 diamond drill holes on the Tyko Project, twelve holes were drilled on the Tyko I Property and ten on the Tyko II Property which are detailed in this release.
  • The Gionet Zone has returned up to 0.38% Cu in soils coincident with VTEM ("Versatile Time Domain Electromagnetic") anomalies and remains to be drill tested following receipt of exploration drill permits.

The 2023 drill program comprised 22 holes totalling 3,028 meters on both the Tyko I and Tyko II Properties. The program included twelve holes targeting the West Pickle area of Tyko I (see news release Feb 1, 2024) and ten drill holes on the Tyko II Property, primarily targeting the Moshkinabi intrusion. Drilling on the Moshkinabi intrusion targeted both massive and disseminated sulphides. 

The primary drill target was massive sulphide mineralization along the base of the intrusion such as that found in a historic trench which returned grab samples up to 1.0% Ni, 0.2% Cu, 0.13% Co, 2.42 g/t Pd, and 0.15 g/t Pt (see news release November 21, 2023). A 2023 VTEMmax survey outlined several isolated conductors located near the base of the Moshkinabi intrusion which could represent additional massive sulphide accumulations (see news release September 28, 2023). Holes TK23-140 and 141 successfully intersected Ni-rich semi-massive and massive sulphide similar to the grab samples from the historic trench, however several other holes intersected highly deformed sulphide facies banded iron formation in the volcanic wall rock to the Moshkinabi intrusion. It is currently thought that many of these VTEM anomalies are due to this wall rock sulphide, however ~50% of the drill holes did not intersect any significant sulphide and these VTEM targets remain unexplained. The fact that the Moshkinabi intrusion has produced basal-style Ni-rich massive sulphides is highly encouraging and the presence of sulphide facies banded iron formation in the wall rock could also serve as a source of sulphur. This style of mineralization warrants additional follow up.

The secondary target was disseminated Cu-Pd-rich mineralization higher up in the Moshkinabi intrusion belonging to the Kejimalda Zone, which has been defined by historical mapping and prospecting over three kilometers of strike length. Disseminated style mineralization was intersected in six holes with widths ranging from two to twenty-four meters. The disseminated style mineralization appears to parallel the lower contact of the intrusion, which dips shallowly the northeast, and could represent a reef-style system. 

The final hole of the program TK23-144 targeted an isolated VTEM anomaly and intersected semi-massive pyrrhotite-rich mineralization with minor chalcopyrite in highly deformed volcanics. It is thought to be volcanogenic massive sulphide ("VMS") style mineralization with potential similarities to the nearby world-class Geco mine that produced over 49.3 Mt of ore grading 1.85% Cu, 3.78% Zn, and 56.2 g/t Ag (Puumala et al., 2020).
