SECT%O/7 > <br />/nlioeucfion <br />9 Exhibit 1-1. Summary of the Status of Specified Facilities at the Van 4 Mine <br />Specified Facilities Facility Status <br />Leach facilities, or heap leach <br />ad Not Present <br />Tailings storage or disposal <br />areas Not Present <br />Impoundments Not Present <br />Waste rock piles Present <br />Stock piles, temporary or <br />permanent Not currently present, but stockpiles will be present when production <br />resumes <br />Land application sites Not Present <br />The Van 4 Mine is not currently operating (i.e., generating ore) and therefore, only <br />waste rock piles (development rock area) are present. Development rock is material <br />that must be excavated to facilitate mine development, but that does not contain <br />adequate metals content to constitute ore. This investigation focused on evaluation of <br />development rock in the existing development rock area to determine if these <br />materials are potentially acid- or tocix-forming. <br />1.3 Land Uses in Area of Mine <br />The post-mining land uses at the Van 4 Mine are established in the BLM Management <br />Plan for the area (San Juan-San Miguel Resource Management Plan, BLM 1985). The <br />affected areas of the Van 4 Mine are included within Multiple Use Emphasis Area E- <br />• Mineral Resources. Management activities for areas with this designation are defined <br />as follows (BLM 1985): <br />Management direction will emphasize mineral development on public lands. <br />Mineral values indicate significant reserves of valuable minerals are present <br />and development is either currently ongoing or will occur in the near future. <br />Other resource uses will occur to the extent they are compatible with mineral <br />development. Limited expenditures of public resources will be used on <br />developing the present land resources. Livestock grazing will continue, <br />wildlife habitat will be maintained where feasible, and cultural resources will <br />receive protection currently afforded by law. <br />As described in the BLM Management Plan, BLM intends to manage this area <br />primarily for mineral development. Motorized recreation is authorized in the area <br />and livestock are permitted. Reductions in livestock use are planned where needed to <br />minimize impacts to mineral development and reclamation. <br />1.4 Description of Rock Materials Exposed by Mining <br />Rock material currently exposed by mining at the Van 4 Mine is development rock. <br />However, once mining operations commence again, ore would also be exposed at the <br />site. Ore is extracted from the Top Rim Sandstone unit, which occurs in the upper <br />portion of the Salt Wash Member of the Morrison Formation. Development rock <br />consists of non-mineralized or weakly mineralized Top Rim sandstone and non- <br />. mineralized siltstone from adjacent rock units. <br />1-3 <br />T164966-Denison Mines\Te
