AbstractDetailed geochemical studies were carried out in 197 5 to determine the distribution and dispersion patterns of uranium, the base metals, and associated elements in bedrock, surficial overburden, and lake and stream waters and sediments. Sampled media were selectively analyzed by a variety of techniques for: Zn, Cu, Pb, Ni, Co, Ag, Mn, As, Mo, Fe, Hg, Sr, Ba, Ti, Al, Ca, Mg, K, V, Cr, Be, La, Y, and U. Multielement regional distribution patterns in both lake waters and sediments provide information indicative of pegmatitic uranium mineralization, disseminated sulphide mineralization, chemical variations in bedrock lithologies, and differences in aquatic physicochemistry. A definite value was found in interpreting hydrogeochemical dispersion patterns in terms of elemental associations based on trace and minor element assemblages outlined for known mineralization, bedrock lithologies and different aquatic physicochemistry within the study area. Reconnaissance exploration for uranium and base metal mineralization can be carried out utilizing lake sediments at sample densities of one sample/ 13 km 2 and 2 to 5 km 2, respectively. Lake waters can provide auxiliary data, particularly in the search for uranium. Detailed exploration can be accomplished using lake waters and sediments. The use of stream waters and sediments for mineral exploration in this area was not worthwhile nor was the chemistry of the overburden indicative of the underlying bedrock lithology.
