Figure 7- Block wall being developed in front of Portal #3 <br />2. Mining Timetable <br />By expanding the mining out to the additional gallery and quarries, selectivity in mining to meet <br />market demands is greatly improved. While the marble throughout the deposit is stunningly white, <br />the delicate veining varies through the geologic section as well as along strike of the deposit. The <br />intent of the operation is to open the quarries as soon as possible in order to explore and develop the <br />marble within those areas. <br />Current operations within the Lincoln Gallery will continue. Access to the Lincoln Gallery is already <br />established through Portals #5-7. Due to variability of the marble market exact mining life for the <br />gallery is unknown. However, it is estimated that the gallery has 50-100 years of mine life if <br />excavated to the approximate depth of the Washington Gallery. <br />Access to the Jefferson Quarry will be established beginning in 2016, but actual quarrying is not <br />expected until 2017. The Jefferson Quarry has approximately 3.0 million cubic yards of marble. The <br />The Pride of America DRMS 112c <br />Exhibit D - 6 12/23/15 <br />
