River Valley PGE Project
Contact-Style PGE-Cu-Ni-bearing sulphide mineralization
The River Valley PGE Project is located in Crerar and Dana townships, approximately 60 km east-northeast of Sudbury in northeastern Ontario, Canada, immediately south of New Age Metals’ River Valley Palladium Project.

 

The mining rights area in the project consists of 95 single cell mining claims covering approximately 2,085 hectares (21.07 square km).

River Valley PGE Project
History
Much of the early exploration for Ni-Cu sulphides occurred in the late 1950s and through the 1960s; this pre-1973 work, which includes exploration programs in the area of the current Project, was focused on exploring for nickel-copper deposits similar to those known at the time in the Sudbury Igneous Complex (i.e., semi-massive to massive sulphide).

 

In late 1998, recognizing that the River Valley Intrusion (“RVI”) may host similar PGE-Cu-Ni mineralization known to occur in the East Bull Lake and Shakespeare-Dunlop (Agnew Lake) intrusions west of Sudbury, partners Messrs. Lorne Luhta, Bob Bailey and Ron Orchard staked a land position in Dana Township and in following up on 1960s sulphide showings discovered (re-discovered) significant PGE mineralization. Pacific North West Capital Corp. (now New Age Metals Inc.), already exploring for PGEs in the Sudbury region, including neighbouring Janes Township, quickly moved to option the new PGE-Cu-Ni opportunity.

 

Since 1999, historical exploration work on the River Valley PGE Property has included mapping, geophysics, trenching and diamond drilling by Mustang Minerals Corp. (South Grid in Crerar Township) and Aquiline Resources Inc. (northwest and into Dana Township). Earlier exploration work was conducted by Falconbridge Nickel Mines Ltd (1965), Tomrose Mines Ltd. (1963-1966), and McIntyre Porcupine Mines Ltd (1956).

Regional Geology
The Project is located within a geologically diverse area that straddles the Superior (Neoarchean), Southern (Paleoproterozoic) and Grenville (Mesoproterozoic) Provinces of the Canadian Shield near Sudbury in northeastern Ontario. Of particular importance to the Project are a series of large, east-northeast-trending, layered, mafic igneous rocks that occur in the region (the East Bull Lake Intrusive Suite; “EBLIS”); this suite of rocks is notable since these rocks have the potential to host economic PGE-Cu-Ni mineralization of the reef or the contact style (James et al., 2002a).

 

The River Valley PGE Project area is underlain by the RVI, one of the three main intrusions that comprise the EBLIS. The RVI is approximately 30 km long and about 15 km wide and is exposed across at least six townships to the east of Sudbury. Easton and Hrominchuk (1999) indicated that the RVI is dominated (~60% of the surface area) by gabbro, norite, gabbronorite, leucogabbronorite, and leuconorite compositions. True anorthosite forms only about 10% of the surface exposures of the intrusion. Regional geophysics shows the RVI associated with a large, positive gravity anomaly (Easton, 2007), suggesting the possible existence of a denser, more mafic (ultramafic) phase at depth.

 

The RVI lies south of the Grenville Front within the Grenville Front Tectonic Zone (“GFTZ”). The Grenville Front is a sharp tectonic boundary that marks the northwestern limit of the reworking of older terranes during the Grenville Orogeny (1.3 to 1.0 Ga) and is recognized as one of the largest known collisional orogens; the uniformly high grade of metamorphism on the Grenville side of the Front indicate that it was the site of considerable uplift. The GFTZ is an ill-defined region up to 30 km across with transitional boundaries that parallels the Grenville Front.
