Project Summary

The Corridor Project is located approximately 50km north of Halls Creek in Western Australia and is considered highly prospective to host both globally significant V-Ti-Fe and Ni-Cu-PGM resources. The project consists of three exploration licences: Corridor (E80/5228), Corridor North (E80/5326), and Corridor South (E80/5327) for a combined total area of 263 km².

Corridor’s V-Ti-Fe potential was identified by MRG Resources in 2018 with the project advanced through detailed remodelling of magnetic data, re-assaying of historical RC drill chips, early-stage metallurgy test work, and review of historical VTEM data. This work – undertaken in conjunction with independent geophysical consultants – highlighted exceptional Ni-Cu-PGM potential that remains inadequately tested.

In 2024, the project was transferred to Orogen Metals Pty Ltd that was founded to facilitate funding initiatives to advance exploration of both the V-Ti-Fe and Ni-Cu-PGM opportunities.

V-Ti-Fe Mineralisation

An underexplored layered mafic intrusion – the Corridor Gabbro – trends through the project for approximately 75 km and varies in width from hundreds of meters to 3 km wide. Magnetic anomalies associated with this intrusion are caused by magnetite that is, where historic sampling has been undertaken, shown to be highly enriched in V-Ti-Fe.

While outcropping magnetite was noted by past explorers, its V-Ti-Fe enrichment was not investigated despite rock chip sampling returning strong results, including:

• TK500015 1.84% V₂O₅ + 21.18% TiO₂ + 70.20% Fe₂O₃
• TK500100 1.78% V₂O₅ + 17.18% TiO₂ + 69.20% Fe₂O₃
• TK500013 1.60% V₂O₅ + 10.41% TiO₂ + 67.34% Fe₂O₃
• TK500014 1.39% V₂O₅ + 14.91% TiO₂ + 66.48% Fe₂O₃
• TK500016 0.94% V₂O₅ + 10.73% TiO₂ + 62.19% Fe₂O₃

Limited reverse circulation drilling, undertaken in 2012 by the then tenure holder who targeted Ni-Cu-PGM mineralisation, included four holes collared over the large magnetic anomaly. Selective sampling of these holes based on visual sulphide identification returned encouraging Ti-Fe grades although V was not assayed for.

Upon acquisition of historic drill samples, MRG Resources re-assayed three of the four drill holes with each returning thick intervals of high grade, magnetite hosted V-Ti-Fe mineralisation. Intercepts include (@ 0.15% V₂O₅ cut off):

Magnetic inversion modelling over the Corridor Project indicates a large volume of potential magnetite mineralisation occurring at shallow depth that has a high likelihood of being enriched in vanadium and associated titanium. A V-Ti-Fe focused JORC Exploration Target is being developed in conjunction with targeting studies for step-out drill testing leading to resource definition programs.

Early-stage metallurgy test work undertaken by MRG Resources indicates favourable characteristics that, if representative of the whole, may be beneficial for production of a magnetic concentrate via low intensity magnetic separation (LIMS). Average grade of magnetite (2.3% V₂O₅) and titano-FeOx/O (2.5% V₂O₅) as determined by QEMSCAN analysis indicates a strong potential to produce a concentrate grade >2% V₂O₅.

While further drilling and metallurgy test work is required, results to date suggest the Corridor Project has the potential to host a globally significant V-Ti-Fe resource of a scale and grade, and with beneficiation characteristics, that could rank it favourably amongst the world’s largest V-Ti-Fe deposits.

Ni-Cu-PGM Potential

Historical exploration at the Corridor Project was limited and mainly focused on Ni-Cu-(Co-Zn) gossans outcropping at the Billymac Prospect in the northern portion of the central exploration licence. Two shallow WMC percussion holes drilled into the gossans in 1979 returned weak Ni-Cu-Co enrichment alongside peak rock chip values of 4.91% Cu, 0.63% Ni, 560ppm Co, 490ppm Zn, and 0.127g/t Au.

An airborne VTEM survey undertaken by a latter tenure holder identified numerous large and strong conductive anomalies along the basal contact of the Corridor Gabbro that included two anomalies beneath the Billymac Gossans. Limited drill testing intersected disseminated-blebby and rarer semi-massive Ni-Cu-Co sulphides at each of the targets confirming metal fertility along the basal contact of the Corridor Gabbro. Notably, the two Billymac conductors and the largest conductor in the southern portion of the exploration licence were not drill tested.

A review of the historical Ni-Cu-PGM focussed exploration, including re-modelling of VTEM conductor plates, has highlighted a number of untested and poorly tested conductors that are considered high priority exploration targets. A program of ground-based MLEM is planned to refine VTEM conductors ahead of drill testing, with the addition of DHEM surveying post-drilling, which has not been undertaken at the project previously.
