FIELD OPERATIONS SamR~s~ Activttles Sampling activities were conducted on April 26, 1995. Access to the Battle Mountain Gold permit area was not secured at the time of field activities; therefore, no direct observations of the mine's workings were documented. Sample collection was limlted to offslte surface water and sediment samples. Surface water and sediment samples, ~MSW/SE-01, were collected from the Rlto Seto east of the mine's permitted area within Castilla County greenbelt property. Samples were collected from the Rita Seco immediately west of the western boundary of the permit area and designated BM-SW/SE-02. Surface water and sediment samples, designated BM-SW f SE-03, were collected from the Rita Seca downstream of signficant lengths (greater than 0.1 stream miles) of scxub-shrub wetlands contiguous to the river. Proposed samples BM-SW/SE-04 were not collected because an adequate stream- wetland evaluation was achieved with the location and collection of samples BMSW/SE- 03. Sediment sample BM-SE-05 was collected from the flowing ditch at the diversion point to the reservoir. The ditch from which BM-SW-0S was collected receives flow from the Rlto Seco diverted approximately 2 miles northeast of the reservoir. A sediment sample (BM-SE-06) was collected from the dry drainage channel downgradient of the tailings disposal facility on the west side of the fence line between Dos Hermanos property and the mine permit area. Non-SamQlina Data Collection Observations regarding flora and fauna habitat associated with the Rito Seto River were documented. Catchable size game fish (trout) were observed st locations east of the Battle Mountain Gold permit area. Numerous, apparently recent beaver dams were observed on the Rito Seco both within the permitted area and to the east within the Dos Hermanos Ranch. Beaver dam placement has resulted in extensive inundation of areas adjacent to the Rlto Seco channel. Scrub-shrub wetland vegetation was noted to be essentially continuous from a point within the permitted area to a point beyond the river's exit from the foothills. a~vsoa~.a~rmeavK - 2 - mR a a+liou
