This study was aimed at assessment of Re migration and its accumulation by organisms within the Zhireken ore field and neighboring territories (Eastern Transbaikalia). To measure the concentrations of Re in biogeochemical objects, the ISP-mass spectrometry method and solutions with known metal content were used. Other metal were determined by AAS. The hyperaccumulation of rhenium by plants growing around Zhireken quarry (up to 60 mg/kg) at a background level of 5-10 ng/g of dry matter was established. The Re content in the reservoir of the bottom part of the quarry (74 µg/l) and the duct (63 µg/l) exceeds the background concentrations by 1,000-5,000 times. The coefficient of water migration Re in the ore anomaly reaches 914 units, which indicates its high migration ability. Re concentrations in soils and ground correlate with Mo, Cu and Fe ones. In plants, this relationship is not established. The Re hyperaccumulation by plants is the basis for the development of technologies for extracting metal from ore materials and reconndissance of rhenium anomalies.
