UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Map Showing Metal 1iferous and Selected Nonmetal 1iferous Mineral Deposits, Sward Peninsula, Alaska Compiled b) Travis Hudson, Martha L. Mi11 er, and William J. Pickthorn Open-file report 77-7968 1977 This report is prel iminary and has not been edited or reviwed for confomity with Geological Survey standards CONTENTS Page Explanatory Note ........................................ 1 Table Headings ------------------------------------------------- 2 Table of Metal1iferous and Selected Nonmetal liferous Deposits -- 4 EXPLANATORY NOTE The map and accompanying table is one of several data components prepared as a foundation for evaluating the mineral resource potential of Seward Peninsula. The data included here are based on pub1 ished 1iterature, consul tations with gedogists fami 1iar with Seward Penin- sula mineral deposits, and the f irst-hand knowledge of the sen4 or author. Two U. S. Geological Survey quadrangle report series, metal 1ic m-Sneral resource maps and summaries of references to mineral occurrences, by Ee H. Cobb, (1972 a-f, 1975 a-c, 1976) have been our principal guides to the mineral deposit data. U. S. Bureau of Mines maps depicting the location of mining claims have been used to identify and locate some deposits not known elsewhere in the 1i terature. The compilation in- cludes the great majority of known mineral deposits on Seward Penin- sula; a few generally or local ly known deposits are probably not in- cluded . As used in this report, Smrd Peninsula extends westward from long1tude 161" to Cape Prince of Hales, is bordered to the south by Bering Sea-Norton Bay, and to the north by Kotzebue Sound-Eschscholtz Bay. On the map, the mineral deposits are numbered consecutively in a general clockwise sequence starting from the Cape Prfnce of Wales area. Mineral deposits are considered to be any natural concentra- tion of useful mineral s. Selected deposits of non-metal 1ic resources, namely fluorite, barite, and graphite, are included. The mineral deposit locations shown on the map are approximate. Cobb's mineral resource maps (Cobb, 1972, a-f) or cited references should be con- sul ted for more accurate 1ocati on information. Geologic studies of Seward Peninsula mineral deposits are incom- plete and, as a whole, do not reflect recent mineral deposit concepts. The level of information concerning specific deposits ranges from ex- tensive (Lost River, No. 37) to vague (Camp Creek, No. 253), and the deposits range in significance from minor occurrences to major re- source concentrations . The presence of several re1atively recent dis- coveries emphasizes that this map and table can only reflect inform- tion as presently known; because this information is necessarily in- complete it is only partly indicative of the actual mineral endowent .of Seward Peninsula. TABLE HEADINGS Map No. and Name(s) Map No. refers to a specific deposit-or group of deposits and serves to key the map to the table. Name(s) are those by which the deposit is prin- cipally known in the literature. Unnamed deposits are identified in parentheses by the name of a prominent nearby geographic feature. Map Coordinates and Map coordinates indicate the position of each de- Quadrangle Location posit on the accompanying map using 1etters for each degree of 1ongi tude and numbers for each degree of latitude. Quadrangle location refers to the standard township and range designation within the indicated 1:250,000 U.S. Geological Survey quad- rangle map. Category Category indicates whether the deposit is a mine, prospect, or occurrence as defined below. Mine (M,N - a mineral deposlt with recorded pro- duction. M - mine with no known post-1950 activity. -M - mine with know or probable post-1950 activity. Prospect (P,P) - a deposit that has been claimed and to some extent explored but lacks evi- dence of production. P - prospect with no apparent post-1950. activity. -P - prospect with apparent post-1950 activity. Occurrence (0) - a deposit that, as far as known, is unclaimed and lacks evidence of expl ora- tion. Occurrences are mainly known from recent government surveys: many have not been included in the compilation. Resource(s) indicates the main carmodity or comnodi ties (most by standard chemical symbols, RE symbolizes rare-earth elements) for which the deposit is note- worthy. Important minor constituents are shown in parentheses. Form and/or Type Form and/or type provides a simple descriptive classification of the deposit on the basis of its geometry and/or general geologic characteristics. Description Description is a brief sumnary of the geologic and mineralogic characteristics of the deposit and in some cases production and historical data. Reference(s) are the principal sources of i nforma- tion for each deposit; the list for each deposit is not comprehensive. 1. (t.C.hlaaof ?A 7 L? 4lswlwW OM @lacarclrlm.
