// PAGE 8 <br />EXHIBIT D <br /> <br /> <br /> <br />Raptor Materials, LLC Cogburn Sand, Gravel, and Reservoir Project February 2025 <br />A Regular Impact (112) Construction Permit Application – Colorado Division of Reclamation Mining and Safety, Office of Mined Land Reclamation <br />This submittal is unable to fully forecast the maximum extent of disturbance within the affected lands <br />expected at any given point in time, beyond an annual basis. As operational extraction and reclamation <br />efforts will vary annually, the timing of extraction, reclamation, and life of operation as forecasted must be <br />based on an initial estimate [refer to Exhibit L: Reclamation Costs], then subsequently verified and <br />adjusted as reasonably determined at the time of the required OMLR Annual Report. If justified by field <br />conditions, a rider to the warranty would follow in due course to reflect current or forecast conditions <br />where such conditions cannot be reasonably attenuated in a timely manner prior to the due date of the <br />next year’s Annual Report. This will serve to assure flexibility and confidence in continued operations until <br />completion of the desired end use. <br />Section (f) <br />A map (in Exhibit C - Pre-Mining and Mining Plan Maps(s) of Affected Lands, Rule 6.4.3) may be used along <br />with a narrative to present the following information: <br />Subsections (i) and (ii) <br />(i) nature, depth and thickness of the deposit to be mined and the thickness and type of <br />overburden to be removed (may be marked "CONFIDENTIAL," pursuant to Rule 1.3(3)); and <br /> <br />(ii) nature of the stratum immediately beneath the material to be mined in sedimentary deposits. <br /> <br />Generally, total soil depth (including all soil horizons) over the property may vary from approximately zero <br />inches to six feet with the potential for a mixture of silt, clay, or gravel outcrops over random areas. Gravel <br />depth may occur from the surface to the underlying shale varying at approximately 23± to 50± feet over the <br />entire property. The underlying shale is generally described as a dark grey and very stiff unit which is <br />expected to be an excellent base for lined reservoirs, and if needed, liner material for the side slopes of the <br />excavations. <br /> <br />Additional geologic considerations are also included in the addendum: Slope Stability Analysis. <br />Sections (g) and (h) <br />Identify the primary and secondary commodities to be mined/extracted and describe the intended use; and <br /> <br />name and describe the intended use of all expected incidental products to be mined/extracted by the <br />proposed operation. <br /> <br />For a diverse list of products to be extracted and/or processed, and sold, they may include but are not <br />limited to the more common products identified in Table D1 – Varra Companies Product List (included as an <br />addendum), or other inert or commonly useful products used for diverse construction purposes, including, <br />but not limited to: structural fill, concrete products, road construction products; and other products to aid <br />the residential, commercial, industrial customer; and for any other infrastructure use. <br />Section (i) <br />Specify if explosives will be used in conjunction with the mining (or reclamation). In consultation with the <br />Office, the Applicant must demonstrate pursuant to Rule 6.5(4), Geotechnical Stability Exhibit, that off-site <br />areas will not be adversely affected by blasting. <br /> <br />Explosives will not be used.
