A ERC <br /> OPERATIONS AFTER 2026 <br /> • The sand plant will be erected early into this timeframe. <br /> • Dredging will occur from March through November annually with average production rate of 1.2 <br /> MCY per year. <br /> • Until the sand plant is running,dredged materials will continue to be routed to the hydro-cyclone <br /> similar to 2025 operations. <br /> • The stockpile configuration shown in the end of year five configuration (Drawing C-8 and C-9)can <br /> accommodate the total volume of material expected to be dredged during this period. However, <br /> the actual volume of dredged materials in the stockpiles will depend on the quantity sold. The <br /> stockpile layout conservatively assumes that no material is sold. Selling the materials is a key <br /> objective of this project, so it is anticipated that the stockpiles will be significantly smaller than <br /> depicted in the drawings. <br /> • The ultimate stockpile configuration shown on Drawings C-10 and C-11 can accommodate <br /> approximately 17 MCY which is approximately 65%of the anticipated materials to be <br /> dredged. This means, as a minimum, approximately 9 MCY of materials will be sold. <br /> • Normal operations when the sand plant is operational (current plan): <br /> o Dredged materials will be directly fed to the sand plant. <br /> o The sand plant will segregate the dredged materials into the desired particle <br /> sizes. Oversize materials will be placed into stockpiles. Water and fines will be pumped <br /> to the settling ponds. <br /> o After dewatering the solids,materials will be extracted from the settling ponds and placed <br /> in one of the site stockpiles.These materials will primarily consist of particles smaller than <br /> #200 sieve size and are likely to contain a significant amount of clay. As a result, these <br /> materials could be beneficial and marketable for projects requiring low permeability <br /> materials. <br /> o The current plan is to transport the primary product(sand)from the sand plant to a load- <br /> out stockpile using a conveyor system equipped with a radial stacker. <br /> • Operations when the sand plant is not operating(current plan): <br /> o The dredging, cyclone, filling, and dewatering processes will be similar to those in the <br /> 2025 operation. <br /> o The hydro-cyclone will be relocated as needed to enhance logistics and efficiency in <br /> material handling. <br /> • Third party trucks will enter and exit from the main mine entrance. <br /> 15 <br />
