Comment Geology and rock and silt geochemical surveys were conducted. Twenty-one areas of zinc mineralization were found in the Arnica, Manetoe and Nahanni Formation. Mineralization is characteristically smithsonite with minor galena. Values from silt sampling ranged from 20-54 ppm Pb and 37-159 ppm Zn. Results for rock chip samples are typically in the 2-4% Zn range with one notable chip sample returning 12.10% Zn over 8 ft. Additional silt sampling and prospecting, combined with detailed mapping, ground geophysics and trenching of known mineralized zones, is recommended.

Activity Sampling
Comment Geochemical stream sediment sampling was conducted in the drainage areas of occurrences B15, B17, and B18. Sample analysis ranged from 20 to 54 ppm lead and 37 to 159 ppm zinc. Assays of grab, and chip samples from Prospecting Permits 306 and 305 include: 0.05% Pb and 12.10% Zn over 8 feet from B1; 3100 ppm Pb and >20,000 ppm Zn from B8; 2750 ppm Pb and >20,000 ppm from B9; 2.6% Zn over 12 feet from B23; and 3.10% Zn over 30 feet from B29. Samples from Permit 304 retuned assays of: 1.15% Zn over 10 feet from B35; 2.75% Zn over 2 feet from B38; 1.40% Zn over 5 feet from B39; and 3.0% Zn over 3 feet from B45.
