Capsule Geology

The area of the Tatsa showing is underlain by Mississippian undivided volcanic rocks of the Stikine Assemblage.

A 0.9 metre chip sample (sample M04A-C109) taken from sheared carbonate altered sericite schist with malachite staining assayed 3.9 grams per tonne silver, 0.35 per cent copper, 0.2 per cent arsenic and 0.11 per cent antimony (Assessment Report 27775).

A number of float boulders mineralized with up to 0.27 per cent molybdenum and 0.10 per cent copper were found in the large glacial bowl draining east through the Tatsa #3 claim, about 250 metres south-southwest of the 0.9 metre (Assessment Report 27775). The Molybdenum rich boulders are likely deposited by the glacier and originated fuaher to the west. They are typically composed of semi-massive to massive siliceous pyrite and minor molybdenite.

Solomon Resources Ltd staked the Tatsa claims in early 2004. Work in 2004 included geological mapping, prospecting and reconnaissance soil and silt geochemical surveys. A total of 49 rock (34 grab, 4 chip and 11 float samples), 571 soil and 13 stream silt samples were collected and submitted for geochemical analysis. No work or sampling was undertaken on the Tatsa #6, #7 claims. Soil samples were collected along the southernmost boundaries of the Tatsa 8 and 9 claims.
