Section 1 <br />Introduction <br />Management Plan, BLM 2008). The affected areas of the Sunday Mines Group are included 10 <br />within Management Area 3 (MA 3): Natural Landscape with Limited,Vanagement. Management <br />activities for areas with this designation are defined as follows (BLM 2008): <br />Management activities are allowed, but limited, on MA 3s. They occur mostly for <br />restoration purposes needed because of natural disturbance events or past management <br />actions. Management activities may include restoration of ecological conditions or <br />habitat components; prescribed burns; wildland fire use, salvage logging following fire, <br />insect epidemics, and/or wind events, hazardous fuels reduction; and invasive species <br />reduction. Temporary road construction and motorized equipment may be used in order <br />to achieve desired conditions; however, most roads would be closed upon project <br />completion. Most MA 3s emphasize non-motorized recreation opportunities, but <br />motorized travel occurs in some areas on existing roads and some trails. Livestock <br />grazing occurs on many of these lands. <br />As described in the BLM Management Plan designation, BLM intends to manage this area with <br />very limited vehicular access including only temporary or existing roads, and some trails. <br />Existing mine reclamation plans established within State permits for the Sunday Mines Group <br />include reclamation of mine facilities and most access roads. Therefore, intensive recreational <br />activities such as all-terrain vehicle (ATV) use are unlikely to occur during the post-raining <br />period. Salvage logging is also unlikely to occur because marketable timber is not present in the <br />area of the Sunday Mines Group. It is possible that short-term activities such as non-motorized <br />recreation, prescribed burns or invasive species reduction (weed control) may occur. <br />1.4 Description of Rock Materials Exposed by Mining 0 <br />Two primary types of rock materials are exposed by mining at the Sunday Mines Group: ore <br />and development rock. Ore is extracted from the Top Rim Sandstone unit, which occurs in the <br />upper portion of the Salt Wash Member of the Morrison Formation. Development rock consists <br />of non-mineralized or weakly mineralized Top Rim sandstone and non-mineralized siltstone <br />from adjacent rock units. <br />Botinelly and Weeks (1957) classified the mineralogy of the uranium-vanadium deposits of the <br />Colorado Plateau including deposits in the area of the Sunday Mines Group. Botinelly and <br />Weeks (1957) classified ore in the Sunday Mines area as Type 1 and Type 2, which exhibit a high <br />vanadium to uranium ratio and moderate to high valance. Dominant ore minerals identified by <br />Botinelly and Weeks (1957) are summarized in Exhibit 1-3. <br /> <br />cm 1-4 <br />TA64866-Denison Mines\Task Order 3 - DMO Sampling and Analysis PlanUask 3.12 - Soil, Ore, Rack Data Assessment RepomSuneay Rock Re port%final report ReportTinal Sunday Mines Group Soil Ore Rock <br />Data Assessment Repor1_051509Am
