Resources
The following table presents the Resources of the Wismut on 1 January 1991. All values are in tonnes uranium (not uranium oxide). Total unmined resources are the combination of reserves plus inferred resources. The total uranium potential are the total unmined resources plus the mined resources. After 1990 there was a little mining in Ronneburg, Niederschlema-Alberoda and Pöhla to reduce the contact surface between uranium ore and groundwater after flooding the mines. In Königstein the cleaning process of mine water still produces uranium today which is sold to international customers. The total production after 1990 is about 1,500 tonnes uranium and is not included in the table.

Famous quotes containing the word resources:
“The great object of Education should be commensurate with the object of life. It should be a moral one; to teach self-trust: to inspire the youthful man with an interest in himself; with a curiosity touching his own nature; to acquaint him with the resources of his mind, and to teach him that there is all his strength, and to inflame him with a piety towards the Grand Mind in which he lives. Thus would education conspire with the Divine Providence.”
—Ralph Waldo Emerson (1803–1882)
“The old, subjective, stagnant, indolent and wretched life for woman has gone. She has as many resources as men, as many activities beckon her on. As large possibilities swell and inspire her heart.”
—Anna Julia Cooper (1859–1964)
“How many inner resources one needs to tolerate a life of leisure without fatigue”
—Natalie Clifford Barney (1876–1972)
