The last month has seen a massive transition in Alaska from planning to execution, from getting ready to go to the field to boots on the outcrop and drills in the ground. Each year the hustle and bustle of the Alaska summer exploration season subsumes virtually everything else (except the Stanley Cup) as field programs launch around the state. This year has been no different with base metal programs in the Brooks Range, gold programs in Interior Alaska and the Seward Peninsula, nickel-copper-platinum group element programs in the Alaska Range, rare earth element projects in Southeast Alaska and copper porphyry projects in the Alaska Range and on the Alaska Peninsula. People, drills, helicopters and time are all in high demand and short supply. In short, pretty much a normal Alaska summer!

Ucore Rare Metals Inc. announced acquisition of its Ray Mountains rare earth element prospect. The Company has conducted initial geochemical analyses of field-concentrated heavy mineral samples from the 11,400 acre property. The initial assay results indicate mineral concentrates containing 5 percent to more than 30 percent combined valuable metals, with a total rare earth element content ranging from 1-8 percent. The samples additionally show high heavy rare earth element content, generally ranging between 20 percent and 30 percent of total rare earth elements, and high content of the strategic metal dysprosium which ranged from 2-5 percent of the total rare-earth-element content. Multiple mineralized stream systems and fluvial basins occur across an 80 kilometer-wide section of the Ray Mountains. Various government surveys during the 1970s and 1980s concluded that significant tin and rare earth element placer deposits are present in the drainages of the Kanuti, Kilolitna and Ray Rivers. The rare metal placers of the Ray Mountains contain REE as monazite and xenotime, tin as cassiterite, tungsten as wolframite, and zirconium as zircon. Minor amounts of niobium and tantalum also have been identified. Additional work is planned for later in 2011.
