Land Status

Land ownership: Federal
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Reference): Primary Reference = Sterne and others, 1984

Comment (Workings): Discovered in 1977, the deposit was explored by more than 125 drill holes in the early 1990's. Lik South will be open-pit. Lik North will probably be developed by underground mining, access will be from the bottom of the Lik South pit.

Comment (Geology): Leach et al, 2005 lists the primary deposit model as sedimentary exhalative Zn-Pb, but the deposit also shows shale-hosted and carbonate replacement aspects.

Comment (Geology): The Lik prospect is a black, carbonaceous shale- and chert-hosted, volcanogenic exhalative, massive, Pb-Zn-Ag sulfide deposit. The deposit strikes northeast and dips about 30 degrees west. The sulfide horizons are thinly bedded, stratiform and confined to carbonaceous shale and chert. The ore consists of fine- to very fine-grained, sulfides in thin bands or massive lenses which occur discontinuously along strike for over a kilometer. The dominant sulfides are pyrite, marcasite, sphalerite and minor galena. Pyrite accounts for about 50% of the sulfides. Barite is also reported. In silver-rich zones, boulangerite and bournonite appear as exsolution blebs in galena. There are three types of sulfide mineralization in the Lik deposit. The most common type consists of thinly-banded, fine-grained sulfides in black shales that occur in the lowest portion of the section. The second type consists of lenses of massive sulfide, quartz, and barite higher in the section. The third type consists of vein and breccia sulfide deposits stratigraphically below the massive sulfide lenses. The Lik deposit is hosted by a sequence of black shales, black cherts, calcareous black shales and occasional calcareous sandstones. The sequence grades upward from the foot-wall of the deposit through the mineralized zone into an oxidized zone without any apparent depositional hiatus. The hanging-wall of the deposit consists of Permian-Triassic, thick-bedded, gray-green cherts and siliceous mudstones. The Permian-Triassic strata either grade downward into black shales or rest directly on the massive sulfides. The Permian-Triassic rocks are overlain by the severely-sheared sole of an overriding, Upper Cretaceous thrust sheet. Complex folding and disrupted bedding are commonly found in the banded sulfides. The deposit is divided into three parts, Lik North, Lik South, and Su. Lik North is adjacent but offset from Lik South by a fault. Su is the southern continuation of Lik South, but on different claims.

Comment (Exploration): Status = Active

Comment (Geology): Age = Potassium-argon dating indicates that the mineralization is Late Mississippian in age.
