The drill hole is located 17 km west-northwest of Inventus Pardo Paleoplacer Gold Project (see Figure 1).

Key Points: 
  • The drill hole is located 17 km west-northwest of Inventus Pardo Paleoplacer Gold Project (see Figure 1).
  • Inventus believes the McCarthy paleoplacer gold occurrence is a separate ancient river system that was depositing gold simultaneously with the Pardo conglomerates and is strong evidence that an extensive paleoplacer gold system occurs in the region.
  • Surface prospecting will investigate whether the favourable gold-bearing conglomerates exist at surface in McCarthy, similar to the Pardo Project.
  • Our principal assets are a 100% interest in the Pardo Paleoplacer Gold Project and the Sudbury 2.0 Project located northeast of Sudbury.
