Windfall East
Location, Access, Description
The Windfall East property is composed of 12 contiguous claims (674.54 Ha) located in Eeyou-Istchee James Bay Territory (EIJB), Quebec Province, within the traditional territories of the Waswanipi Cree First Nation, approximately 95 km south of Chibougamau (Qc) and 240 km NE of Val-d’Or (Qc). The claims are part of the Skyfall Nickel project of Vior Inc. and Globex retains a 2% Net Smelter Royalty (NSR) on it.
The Windfall East property is accessible from Lebel-sur-Quevillon or Chibougamau via a complete network of well-maintained logging roads. The Windfall advanced gold exploration project of Windfall Mining Group is located about 50 km west. A high-voltage power line runs 40 km west of the property.
Geology and Mineralization
The Windfall East property is located in the Abitibi Subprovince of the Canadian Shield, about 6 km northwest of the Grenville Thrust. Rocks of the property are located at the base of the Urban-Barry Greenstone Belt (UBGB), a complex and ancient volcano-sedimentary sequence (2791 Ma) which is considered to be a fragment of the pre-Abitibi basement (Bandyayera et al., 2004b, Rhéaume and Bandyayera, 2007). They are generally metamorphosed to greenschist facies and locally reached amphibolite facies ; the regional metamorphic gradient generally increases eastward towards the Grenville Front (Joly, 1990).
Rocks of the Windfall East property consist of a succession of mafic to felsic volcanic assemblages with a dacitic volcanic center and significant sequences of mafic-ultramafic flows to the south/southeast, as well as other ultramafic units within the Grenville Province parautochthon. Thin layers of exhalative sediments (cherts and iron formations) and detrital sediments (sandstone, mudstone, etc.) are interbedded within the volcanic rocks (Vior website, August 2025). The Milner fault strikes E-W in the northern part of the property.
As for Rhéaume and Bandyayera (RP2006-08), the history of the area “comprises the formation of a pre-Abitibi basement consisting of ancient volcanic rocks (Fecteau Formation, 2,791 Ma), the opening of an ocean basin and the formation of oceanic crust with the periodic development of island arcs between 2730 and 2707 Ma and the closing and imbrication of this basin during the Kenoran Orogeny”. This rich and long history involves the setting up of different styles of mineralization at each stage. Following Bandyayera et al. (RG2003-07), three major categories of mineralization have been identified in the Lac Hébert region: orogenic gold veins, volcanogenic massive sulfides, and Cu-Ni-Co ±PGE mineralization associated with ultramafic rocks. The volcano-sedimentary units of the UBGB have been considered until now as equivalent to volcanic cycle I (2,720–2,730 Ma) of the Chibougamau Segment (Bandyayera et al., RG2003-07) in which numerous base metal and gold mines have historically been brought into production.
The Urban-Barry belt is home to important deposits such as Windfall (Proven and Probable Reserves of 12.2 Mt @ 8.06 g/t Au and 4.18 g/t Ag (Andrieux et al., 2023 – NI 43-101 Technical Report Feasibility Study for the Windfall Project)), Barry (Measured and Indicated Resources of 1,916,000t @ 2.68 g/t Au, (Bonterra NI 43-101 Technical Report, June 2021)) and Gladiator (Measured and Indicated Resources of 1,413,000t @ 8.61 g/t Au (Bonterra NI 43-101 Technical Report, June 2021)).
According to Vior’s interpretations, “the units and structures associated with the Gladiator deposit continue onto the Skyfall project”. Structures similar in orientation to the Mazères fault (NE-SW) bordering the Windfall deposit have been interpreted on the magnetic survey of the Skyfall project. Vior also identified two (2) favorable environments for Ni-mineralization in the area of the property (Vior Website, August 2025) : 1) Mafic-UM assemblages in the UBGB and 2) UM intrusions and komatiitic flows in the Grenville Province.
History
The property area has seen a great deal of historical exploration work spanning from 1943 to 2009, with no historical resource estimates or production for that period. The majority of historical work done in the area was completed west and southwest in the area of Windfall and Barry Lake. Few geophysical magnetic and electromagnetic-VLF surveys were completed on the property.
Till sampling by Vior in 2020-2021 highlighted strong Au-anomalous clusters including in the area of the Windfall East claims. Between 2022 and 2025, Vior carried out geological mapping (GM72749, GM74180, GM74408) and helicopter-borne Mag and EM survey (GM73433) on the Skyfall project in order to better understand the stratigraphic sequence in this area. A detailed history of the property is proposed in GM74408 (Guay and Blanchet, 2025).
Resources and Potential
The Windfall East property is located in one of the few areas in Abitibi and the Urban-Barry Belt that remains largely unexplored (only a few drill holes have been recorded) and located near a first-class deposit (Windfall).
Vertical gradient of the magnetic field (geophysical compilation map above) shows a strong positive anomaly centered on the Milner fault on the Windfall East claims which could correspond to UM rocks. Exploration work by Vior is still ongoing.
