Superior’s “next Mount Isa” the Victor Project comprises four exploration permits covering a total area of 438 sq km. This Tier 1-potential, lead-zinc exploration project is located within the Carpentaria Zinc Province in north-west Queensland and is considered an industry-leading opportunity to discover a world-class, Mount Isa-style zinc-lead-silver-copper deposit.
Work conducted by the Company indicates that stratigraphy prospective for the discovery of Mount Isa-style deposits is likely to be present under moderate sedimentary cover within the Victor Project area. This area is relatively unexplored. Superior’s exploration strategy is based on the mechanism of geochemical “leakage” of key metals (lead, zinc and copper) from a deeper Proterozoic mineralised basement source into the younger overlying sediments.
Geochemical Leakage into Surrounding Rocks and Overlying Cover
Superior understands that there are two important types of “leakage”:
Historical Airborne Surveys
The north-west Queensland area is blessed by almost complete coverage by airborne magnetics and radiometrics. In addition to this coverage there are numerous historical airborne EM surveys available which have been largely ignored by explorers.
Superior has acquired most of the EM surveys in digital form and processed a number of surveys to produce conductivity sections. Many of the surveys contain anomalies over conductive graphitic sediments which makes interpretation for mineralisation difficult.
However, the surveys provide a view of the stratigraphy in covered areas. As mineralisation is often associated with graphitic sediments the location of these conductive units can assist the delineation of prospective areas.
