Trenton Canyon Gold Mine

The Trenton Canyon Gold Mine is a gold mine located in Lander county, Nevada.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Type: R
Description: The Roberts Mountain Thrust fault and the Golconda Thrust fault both affect rocks in the region of the mine

Type: L
Description: The West Side Fault is a major N-S-trending range-front fault bounding the Battle Mountain block on the west side of the range, and is adjacent to the North Peak deposit. The Oyarbide Fault is a NE-trending fault that transects the range, with the Trenton Canyon deposit lying south of the fault and the North Peak and Valmy deposits lying north of the fault.

Analytical Data

Ore: Gold


Comment (Location): The North Peak orebody center is 3.5 km WNW of the Trenton Canyon orebody center, and the Valmy orebody center is 6 km NNE of the Trenton Canyon orebody center. Even if one considers orebody edge-to-edge distances, this MRDS record probably contains three separate deposits. The Valmy orebody edge is separated from the Marigold 30 gold zone by only 1 km, so the Valmy is more logically part of the Marigold district. Also a bit confusing is the fact that the summit of North Peak is much closer to Valmy than it is to the North Peak mine.

Comment (Commodity): Ore Materials: free gold

Comment (Development): A joint venture involving Bow Valley Mining and Santa Fe Pacific discovered the main Trenton Canyon deposit (North Peak ) in 1988, as a result of follow up work on a stream sediment anomaly. 1989 drilling defined the mineralization and the deposit was drilled out from 1990 to 1994, at which time Santa Fe bought out Bow Valley's interest in the deposit. The Valmy deposit was found in 1989 just north of Hecla's Trout Creek deposit, and the two were consolidated when Santa Fe bought out Hecla's interest in 1992. An additional 140 drill holes were completed at Trenton Canyon in 1996 to define and extend mineralized areas and to investigate two new targets. One new zone of shallow oxide mineralization was encountered in the Valmy deposit area. The second, called the Hollywood zone, is on a ridge northeast of the Trenton Canyon deposit where seven drill holes have intercepted a high-angle zone of near-surface oxide mineralization with grades between 0.03 and 0.13 opt in intercepts 40 to 105 feet thick. Construction began on the Trenton Canyon project in early 1996, and by the end of that year, Santa Fe had begun loading ore mined from the North Peak deposit onto the heap leach pads at a rate of 30,000 tons per day. Gold-laden carbon from the leach pads was processed at the Lone Tree Mine facility. Newmont Gold Company acquired the properties when it merged with Santa Fe Pacific in May 1997. The mine was expected to begin producing at a rate of 70,000 ounces per year in 1997, increasing to about 100,000 ounces per year later in its eight-year projected mine life. In 1995, reserves increased 14 percent from 517,000 ounces to 590,000 ounces, contained in more than 20 million tons of ore. The first gold was produced in early 1997.

Comment (Geology): The two pits at the Valmy deposit are hosted entirely in the Valmy Formation, which in the pit area, is divided into an upper and a lower unit separated from each other by a low-angle thrust fault. The North Peak deposit is hosted entirely within the Havallah Unit, which is divided into three subunits in the pit area: a basal siltstone/limestone unit, a middle sandstone unit, and an upper chert/siltstone unit. The deposit is localized in a heavily fractured zone at the intersection of three high-angle Tertiary faults.

Comment (Identification): The Trenton Canyon Project is composed of three distinct deposits, the North Peak, Valmy, and Trenton Canyon deposits.

Comment (Deposit): All three deposits are structurally-controlled, sediment-hosted gold deposits

Comment (Economic Factors): In 1996, the deposit was estimated to contain a resource of 37,149,000 short tons of mineralized material grading 0.03 ounces of gold per ton. Newmont includes the Trenton Canyon Project production with that from the Lone Tree mine, so individual production data for Trenton is not available.

Comment (Location): The Trenton Canyon Project is located on the northwest flank of Battle Mountain and spans Trout and Cottonwood Creeks in Humboldt and Lander counties. UTM is to the Valmy Pit, from which the first ore was mined. UTM of the North Peak Pit is 4500400N, 481400E. UTM of one of the more centrally located of the Trenton Canyon Pits is 4499300N, 484400E. Actual location of the Valmy and North Peak pits and heap leach facilities is on private land, but the access and haul roads and the Trenton Canyon pits lie on both private and BLM administered lands. The pits of the North Peak and Valmy deposits are located in Humboldt County while the Trenton Canyon deposit workings are located in Lander County. The North Peak orebody is over 3 km WNW of the Trenton Canyon orebody, and the Valmy orebody is over 6 km NNE of the Trenton Canyon orebody. So this mine actually contains three separate deposits. The Valmy orebody is really part of the Marigold deposit.

Comment (Workings): The mine project is developed by several open pits
