Comments on the geologic information

  • Geologic Description = Woewodski Island has complex geology that is largely covered by thick vegetation and is further complicated by a prominent structural zone that crosses it and continues north along Duncan Canal. Brew (1997 [OF 97-156-J]) maps the rocks on Woewodski Island as Mesozoic phyllite; Triassic, Hyd Group felsic and intermediate volcanic flows and breccia, limestone, and argillite; Mesozoic gabbro; and Cretaceous diorite, but the exact relationships and distribution of these rocks requires more detailed mapping. Woewodski Island has lured prospectors since at least the 1920's and there are numerous stories and rumors about people who have prospected there and what they found, many of which cannot be documented or verified well. For instance, it is common knowledge that there was a major drilling program carried out by a private company east of Harvey Lake in the mid-1970's and Williams (1953) mentions a prospect of unstated type somewhere between Harvey Lake and what is now called Harrys Lake. In addition, since the 1970's various parts of the Island have been examined by a succession of companies, including Resource Associates of Alaska, Cominco Exploration, Houston Oil and Minerals Westmin Resources, and others, as well as private individuals. The details of at least some of the work by Houston Oil and Minerals in late 1970's and 1980 have been filed with their notice of assessment work in the Petersburg Recorders office (Book 10, pages 933-971, and Book 12, pages 687-738). Most of the Island has been staked at one time or another in the last 20 years and sampled geochemically, some areas repeatedly. In other words, there has been much more work on Woewodski Island, some going back 80 years, than cannot be documented. It is likely that additional mineral occurrences were found as a result of this work, perhaps many more. The details of the types of deposits that were being searched for in specific exploration work are largely undocumented now but in general the search was probably mainly for gold until the 1970's and since then for volcanogenic massive sulfide deposits.
