Summary and conclusions: <br />The environ encompassing the King I and King II Mines is a microcosm of complexity. <br />The waters which enter this environ come from several sources. In addition the chemical <br />signatures of these sources vary over time. Low TDS water from the La Plata River, via the <br />Hay Gulch Ditch can mix with regional rainwater and existing shallow aquafers to produce <br />mixed and ever changing water sources. The data used in this monitoring report is a series <br />of "snapshots" taken quarterly. The analysis of these snapshots gives a different assortment <br />of data points each quarter that can and do bounce all over the spectrum. A significant <br />example is the depth to water in the King II Down - gradient Well which in one quarter was <br />almost artesian at 2 inches and in a different quarter dropped to 100+ inches below grade. <br />Another example is the level of Manganese in the King I Wiltze Well. This parameter varies <br />from non - detect up to 2.5 mg /L while showing a significant downward trend over the near <br />ten -year monitoring period. <br />The single notable finding of the trend analysis is that most parameters remain <br />somewhat constant [linear] over long monitoring cycles, while others trend upward and still <br />others trend downward. Examples of the former are found in the King II Up- gradient well <br />where Calcium, Magnesium, and Manganese trend upward significantly. Examples of the <br />latter is the downward trend in Iron in the King II Up- gradient Well and Manganese in the <br />King II Down - gradient Well. <br />Even though most trends are linear and mostly flat, individual quarterly readings run <br />the gambit from tight clusters around the linear trend to widely varying values along a trend <br />line. This high degree of variability is in keeping with natural occurrences within this environ <br />[Hay Gulch] and not as a result of mining activities <br />In conclusion: CDS performed trend analysis on all of the data submitted by GCC to <br />the State of Colorado, Division of Reclamation, Mining and Safety and referenced in their <br />letter dated April 21, 2014. The complex nature of the interaction of various water sources <br />within the Hay Gulch environ precludes straightforward interpretations of the presented <br />data. Simple models using precipitation are invalid due to the interaction with highly <br />soluble soils along the Hay Gulch valley and an irrigation ditch carrying low TDS water. <br />Variations in measured parameters are most closely related to what appears to be a long <br />term warming cycle, not related to global warming, where more effects of reduced water <br />supplies and found more often than precipitation driven changes. <br />If you have any questions please call.
