Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020005 Forest or Resource Area: DEERLODGE Owner: M Impact: V Report: Atlantic & Pacific-Viking-Western Pacific This area is treated as one property because geology and environmental problems are continuous and related across the area. The area contains 3 adit discharges, a large tailings pile with mass-wasting problems, and some mass-wasting of dump material from the Atlantic and Pacific adit (see map). In addition, the Atlantic and Pacific contains a large open cut on private land which has been mined in recently under a Department of State Lands operating permit. The area lies along the northwest trending Mammoth Fault, a major high angle structure which played a part in localizing both the Tobacco Root Batholith (Reid, 1957) and mineralization. The Atlantic & Pacific has been the only productive mine at the site. Gold ore was mined from a fractured aplite dike bounded on and associated with Cretaceous granodiorite on the north, and in contact with Archean gneiss on the south (Winchell, 1914; Tansley and others, 1933). The ore contained quartz and auriferous pyrite and occurs veins and disseminated in the country rock. Most was mined from surface workings, but there are more than 600 feet of underground workings. The portal is located on national forest ground and discharges water. Water may enter these underground workings from the large open cut above (R. McCulloch, MBMG, oral communication). Approximately 75,000 tons of tailings are also present at the site. The tailings contain high gold values (.026 oz/ton) but low silver and base metal values (see map). They are being eroded during storm events into an adjoining drainage where they contaminate springs feeding Park Creek. On the Western Pacific, or Viking property, granodiorite and aplite with mineralized shear zones and disseminated pyrite was also mined, although metal values from samples taken were low (see map and USBM MLA-95-83). Despite the poor sample values and the low potential assigned to the property by O'Neill and others (1983), explorationists have done some recent drilling. Probably the extensive area of altered rock and anomalous gold have generated some optimism for finding low grade bulk tonnage gold deposits. Two short caved adits discharge water on the Western Pacific. The dumps associated with the discharges contain only weakly iron stained rock and amount to only a few hundred tons. The dominant mine in the area is the Atlantic Pacific Mine, located at the top of the ridge. All other mines are located within the South Boulder River drainage, below the A-P. Although sulfides were not strongly evident, several adits indicated low pH and high SC. As the area is large and hydrologically complex, there are several sampling sites. Samples were collected as per the MBMG-USFS Quality Assurance Plan and the MBMG Standard Field Operating Procedures. JAPS10M: Located in the tributary drainage to Park Creek below the tailings wash area. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. JAPD10H: Located next to JAPS10M where tailings and soils are mixing near the stream The sample will be analyzed for Total Metals only. The sample is a grab sample at the stake. JAPS20H: Located at the adit discharge point. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam-bucket and stopwatch. JAPS30L: Located the head of Park Creek above within old workings. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam-bucket and stopwatch. JAPS40M: Located at caved adit discharge adjacent to Park Creek. The sample will be analyzed for Dissolved Metals only. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. JAPS50L: Located on Park Creek upstream of adit discharge. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam-bucket and stopwatch. JAPS60M: Located on Park Creek downstream of the main portion of the "Park Creek Tailings". The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam-bucket and stopwatch. JAPT20H: Located on the main portion of the "Park Creek Tailings". The sample will be analyzed for Total Metals. JAPS70L: Located on Park Creek above the confluence with the dry tributary stream to Park Creek. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. JAPS80L: Located on tributary to Park Creek above mine workings. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. JAPS90L: Located on tributary to Park Creek below mine workings and above the confluence with Park Creek. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. |
