The Hilltop-Slaven project is a sediment hosted, Carlin-type deposit located along structurally controlled intersections within the siliceous upper plate rocks or larger, buried disseminated deposits located in the carbonate lower plate rocks along the Battle Mountain-Eureka trend.


The project area is located approximately 20 kilometers southeast of Battle Mountain along the northern and central portion of the Shoshone Range, Lander County, Nevada, between Newmont's Phoenix complex and Barrick's Cortez complex.

Land Status

Newmont controls over 52 square kilometers of mineral rights through railroad, "checkerboard" private minerals within the area of interest.


Previous exploration and mining during the 1970s in the area targeted barite. Several open pits were mined through the early 1980s. The largest barite mines in the area include the Barse and Bante mines. In 1983, geologists working for Resource Associates of Alaska discovered gold-bearing outcrops in the Slaven Canyon area. Since that time, the area has seen a fair amount of exploration resulting with the delineation of seven historic, non-NI 43-101 compliant resource areas. Two historic resource estimates have been completed on the deposit known as Area 1 ranging from 70,000 to 90,000 ounces of gold. The Newmont checkerboard land sits immediately adjacent to these areas and has seen intermittent exploration over the years.


The majority of the property position consists of siliceous Paleozoic sedimentary rocks of chert, argillite and quartzite. These deep marine sedimentary rocks were thrust over autochthonous, carbonate-rich, continental slope rocks during the Devonian-Mississippian Antler Orogeny along the regionally extensive Roberts Mountains Thrust. Autochthonous carbonate rocks, the principal host for nearby Carlin-type deposits at the Cortez complex, are not exposed on the property, but likely occur extensively at depth beneath upper plate rocks. Major north-south, northwest and west-northwest striking fracture systems commonly host intrusions of late Eocene age crosscut allocthonous and autochthonous sequences. These fracture systems are associated with gold and/or silver mineralization in autochthonous carbonate rocks, including the large Carlin-type deposit at Pipeline. The strongest gold and silver mineralization occurs where the intersecting fracture sets have the highest density. These intersection zones are commonly associated with broad areas of decalcification of carbonate units and more restricted silicification and illitization/kaolinitization of both clastic and carbonate units. Gold mineralization is largely confined to fractures in deposits contained within allochthonous chert, argillite and/or quartzite because of the non-reactive nature of these rocks.


Newmont maintains an extensive database for the Hilltop-Slaven project.
