The Quality Control of Assays webcast will demonstrate how to meet the assay quality requirements of NI43-101. Topics to be discussed include: duplicate data collection, use of standards and blanks, simple statistics in the evaluation of standards, recognition of outliers, binary graphs as an interpretive aid to evaluating duplicate data, and displaying and analyzing data. Emphasis will also be placed on the use of simple statistical approaches that can be used to quantify data quality. http://bit.ly/2eSLvKz #mining

The Taum Sauk plant is an open-loop pure pumped operation: unlike some other pumped storage sites, there is no natural primary flow into the upper reservoir available for generation. It is therefore a net consumer of electricity; the laws of thermodynamics dictate that more power is used to pump the water up the mountain than is generated when it comes down. However, the plant is still economical to operate because the upper reservoir is refilled at night, when the electrical generation system is running at low-cost baseline capacity. This ability to store huge amounts of energy led its operator to call Taum Sauk "the biggest battery that we have".

Construction on Taum Sauk began in 1960, at the time, it was by far the largest pumped storage plant in North America in a number of measures, and was considered a major milestone in the development of pumped storage technology. In 1999, the plant was upgraded with units capable of 225 megawatts (302,000 hp) apiece.

On December 14, 2005, a catastrophic failure in the upper reservoir dam put the plant out of operation until it was rebuilt, recertified, and reopened on April 21, 2010. The new upper reservoir dam, rebuilt from the ground up, is the largest roller-compacted concrete dam in North America.
