<br /> It is estimated that, at a minimum, 8000 and a maximum of 16500 yds3, of overburden
<br /> would need to be removed to reach the sandstone layers below. The overburden is a
<br /> clay/gravel/rock mixture with little vegetation growing. The overburden may be used
<br /> for fill, pond lining, and other such uses on Twin Buttes property.
<br /> Removal of the overburden will be based upon the demand for the underlying
<br /> sandstone, thus it may be decades before the over burden is moved.

<br /> If the overburden is not utilized elsewhere, it will be used to re-contour mined areas and
<br /> then top soiled, if possible. See Map C-2 (following page).
