Nickel, Copper, Cobalt, PGE’s
The Chip-Loy/Roberts prospect is comprised of forty-two (42) unpatented mining claims located on State of Alaska public lands wholly within the McGrath A-3 Quadrangle. While the prospects (Chip-Loy and Roberts) are described separately, it is noted that geophysical data suggests the Roberts prospect is part of a belt of similar deposits that includes the Chip-Loy prospect. As such, Nova has combined the two prospects into single project.
The Chip-Loy massive sulphide Nickel, Copper and Cobalt (Ni-Cu-Co) prospect was first discovered and staked by prospectors Ed Chipp and Robert Loy in the early 1960s. Since then numerous geologists from industry and government have visited and sampled it. It is located adjacent to Straight Creek, one of the headwater tributaries of the Middle Fork of the Kuskokwim River. It consists of an irregular, steeply dipping layer of massive to disseminated, nickelian pyrrhotite accompanied by other sulfides in an elongate, composite, diabase intrusion. The diabase, which ranges from gabbro to diorite, has been described as a pipe in plan view or as a dike. The intrusion trends in a northeast direction and cuts mid-Silurian Terra Cotta Mountains Sandstone, a formation of the Dillinger subterrane, a continental margin assemblage of Lower Paleozoic age and has been assign as early Tertiary age.
The Roberts Nickel, Copper, Cobalt and Platinum Group Elements (Ni-Cu-Co-PGE) prospect is in a differentiated, mafic-ultramafic sill that cuts silty limestone and shale of the Late Cambrian to Early Ordovician, Lyman Hills Formation, the oldest facies of the Dillinger subterrane. The mineralization at the Roberts prospect is mainly disseminated and network-style sulfides with a notable content of platinum group elements (PGE) in the lower and middle part of the sill. This prospect includes the oldest facies of the Dillinger subterrane and believed to be correlative with Late Triassic feeders in the Tatina River Volcanics (a subdivision of the Middle Devonian to Lower Jurassic Mystic subterrane).
- Chip-channel samples from the Chip-Loy deposit contain a number of historical disseminated and massive Ni-Co-Cu sulfide sampling
- Roberts prospect has notable content of platinum group elements
- Drilling planned to understand the extent and expand on the known massive sulphide Ni-Co-Cu mineralisation.
