Comments on the geologic information

  • Although best developed in the Raspberry Formation, small scheelite occurrences are ubiquitous throughout the Eugene Mountains where granodiorite plugs come in contact with limestone beds. One such occurrence, the Danner Mines, is located in the Triassic siliciclastics unit at the head of Pole Canyon, about 2.5 miles northwesterly from the Nevada- Massachusetts Company Mines. The old Red Hawk and Ben H. Jackson Mines are within the Danner properties as are several prospects at the head of Bonita and Woody Canyons. Rocks exposed in the area consist of a sequence of dark lavender to black pelitic strata interbedded with thin lenses of finegrained channel sandstone and quartzite and with thin, discontinuous lenses of limestone. The metasedimentary rocks are cut by numerous small stocks, plugs, and dikes of granodiorite. In addition, dikes of andesite, aplite, and leucogranite are common in the area. The intrusions often exhibit sericite-clay type alteration. A moderately sized stock, immediately southwest of the Danner Mines, exhibits a fresh granodiorite basal exposure and grades upwards into a quartzrich, pervasively sericitized leucogranite cupola. Scheelite mineralization occurs in two sets of quartz veins in the granodiorite and in skarn developed in limestone. The quartz veins are commonly 1 inch to 1 foot thick and are spaced about 10 feet apart. The veins are oriented N30?E, 55?SE and N70?E, 60?SE. They consist of white quartz and minor adularia and muscovite, and in places, are stained with copper and iron oxides. The veins commonly contain about 0.01% WO3. The most significant scheelite mineralization in the Danner area occurs as skarn replacement of limestone. Johnson and Benson (1963) reported that between 1917 and 1950 about 470 tons of ore grading from 11 to 2.5% WO3 was produced from several of these deposits in the Danner area. Located at the SE corner of section 17, T34N, R34E, the largest deposit has approximately a 600- foot strike length and 4-foot thickness. The deposit is developed in a limestone bed that has been irregularly replaced by an assemblage of garnet, epidote, quartz, diopside, and 0.3 to 2% scheelite, 0.2 to 2% sphalerite, and traces of molybdenite.

Comments on the workings information

  • The historic tungsten mine was developed by crosscuts, drifts and a winze. More recent prospecting has been surface work.

Comments on other economic factors

  • In 1990, the estimated gold resource was 2 million tons of ore grading 0.03 ounces of gold per ton.
    Between 1917 and 1950 the Danner area mines produced about 470 tons of ore grading from 11 to 2.5% WO3.

Comments on development

  • Historically, the mine was a tungsten mine. In 1917 the claims were owned by Nagle and Campbell of Winnemucca who drove a 40-ft cross cut and drifted 35 ft along a steeply-dipping ore bed and sunk a 20-ft winze on it. In 1928 property was owned by Murphy and Brechtel of Winnemucca who leased it to Leverett Davis in 1942. In 1950 the Tungsten Lead Co. drove about 140 ft of new drifts and produced 142 tons of noncommercial ore. By 1956, R. E. Danner had obtained control of the property and other nearby prospects. A small gravity concentrating plant was installed west of the fork in Pole Canyon. During the late 1960s and early 1970s, Danner produced some scheelite concentrate from the property that was sold to Kennametal in Fallon. Most of the production during this period was from a small open pit along the north border of sec. 16, north of the old Red Hawk adit. The more recent work has been on a gold prospect in the vicinity of the old scheelite mine. Danner planned to sell the claims in 1997.

There are three known ledges of ore believed to be part of one continuous ore bed at least half a mile long. Scheelite mineralization within the beds may not be continuous, but confined to irregular shoots at points favorable to mineral deposition.
