Structure: Paleozoic thrusting and folding and Tertiary age high angle faulting have affected rocks in the mine area. Limestone beds are gently folded along ENE-trending fold axes, forming anticlines and synclines that plunge 10-40 degrees to the east. The dominant Tertiary fault sets strike northwest and north-south; other sets strike east-northeast and northeast. The Gold Bar deposits are located in a window of lower plate rocks below the Roberts Mountain Thrust and lying along the NW-trending Battle Mountain-Eureka Trend of mineral deposits.
Alteration: Mineralization at Gold Bar is closely associated with major decalcification and to a lesser extent with silicification of host rocks and jasperoid development along high-angle structures. Also evident is remobilization of carbon and oxidation and redistribution. Minor bleaching, calcite veining, argillization. All alteration types occur mainly up dip from the feeder structure. The oxidation of pyrite and subsequent remobilization of iron oxides have produced spectacular brick-red to dark yellow brown banding in the oxidized, decalcified limestone. In many areas the ore exhibits intense liesegang banding. Most of the calcite veining is characterized by 0.1-30 cm veins located up dip from the orebody. Argillization is rare. Illitic clays have been locally altered to montmorillonite and allophane.
Commodity: Ore Materials: NATIVE GOLD Gangue Materials: Calcite, quartz, hematite, limonite, clays, barite, Mn oxides, stibiconite in oxidized ore. Pyrite, calcite in jasperoidal ore. Orpiment an drealgar
Deposit: The Gold Bar deposits occur along the crest of a large east-west-trending antiform in thin-bedded lower plate carbonate rocks, where mineralizatoin was localized by NW- and NE-trending structural conduits. The Gold Bar, Goldstone, and Gold Canyon orebodies are hosted by thin-bedded, non-fossiliferous limey mudstone of the Upper Denay Unit 2, and are higher grade, more stratabound, and have well-developed bedded jasperoids. The Gold Pick, Gold Ridge, and Cabin Creek orebodies are hosted by thin-bedded fossiliferous limestone of the Bartine Member of the McColley Canyon Formation, and are lower grade, more structurally controlled, and have spotty basal jasperoids. Petrographic data suggest that gold mineralization postdates silicification and is contemporaneous with, or immediately postdates, decalcification. Three ore types are known: 1) oxidized, 2) jasperoidal, and 3) carbonaceous. The orebody consists mainly of oxidized ore with small amounts of jasperoidal and carbonaceous ore. The carbonaceous ores are twice the grade of the oxide ores. The Gold Bar deposits are located on the crest of a NNW-trending horst of Lower Plate Devonian Limestone covered by a thin veneer of Quaternary gravels and Tertiary volcanics. Mineralization is controlled by a NNW-trending fault and structural intersections with NE-trending cross faults. The recently discovered Millsite deposit lies 1000 feet WNW of the Gold Bar Mine and contains about 150,000 ounces gold at a grade of 0.09 opt gold (1.6 million tons @ 0.091 opt gold) at a depth of approximately 500 feet. The overall shape of the Gold Bar deposit is like a flattened cigar. Gold occurs as micron-sized grains in decalcified zones and along fractures in silicified zones. Petrographic examination and metallurgical testing indicate that the gold is not encapsulated by silica.
Deposit type: Sediment-hosted Au
Development: Numerous companies explored the Roberts Mountains for precious metals deposits beginning in the 1960s. Regional reconnaissance exploration activity by Atlas Precious Metals discovered gold-anomalous jasperoid along the southwest flank of the Roberts Mountains in 1983. Atlas drilled 16 wide-spaced shallow exploration holes, one of which intersected thin gold mineralization (5 ft @ 0.13 opt gold). The following year, the Gold Bar deposit was discovered with the completion of hole number 28, which intersected 110 ft @ 0.138 opt gold starting at a depth of just 15 feet below the surface. Grid drilling of 270 holes on 100-foot centers began in the summer of 1984 and defined the Gold Bar deposit with a reserve of 2.8 million tons of ore grading 0.09 ounces of gold per ton. Mining began in 1986 with first production in 1987. Construction of the mill was completed in January, 1987 with an initial capacity of 1500 tpd., and was expanded in 1988 to its final capacity of 3000 tpd. It employed carbon-in-leach technology with gold recoveries of >90%. Atlas began reconnaissance mapping and sampling east of the mine in 1986, which resulted in the discovery of the nearby Goldstone, Gold Ridge, and Gold Pick orebodies in 1986-87. Subsequently, other companies identified additional nearby gold resources: the Cabin Creek resource was discovered in 1987 by American Copper and Nickel on claims joint-ventured with Nerco Minerals, and in 1988, Phelps Dodge Mining Company discovered the Gold Canyon deposit on claims leased from NL Baroid. Atlas acquired these two properties in 1991 and 1992, to add to the overall Gold Bar district inventory of resources. Mining at Gold Bar was completed in 1990, although stockpiled refractory ore from this deposit was processed through the mill after mining ceased. Production ceased in 1994. A total of over 286,000 ounces of gold was produced from the Gold Bar deposit between 1987 and 1996. Atlas negotiated a series of joint-venture agreements with other mining companies between 1994 and 1999. Homestake Mining Company entered into a joint venture in 1994 for exploration of the pediment area south and southeast of the Gold Bar mine. Homestake conducted CSAMT surveys and drilled 17 exploration holes on the area south of Gold Bar in 1995 and 1996. The joint venture was terminated in 1996. Atlas discovered the Millsite deposit in a down-faulted block west of the Gold Bar mine in 1995. Later that year, Vista Gold explored the immediate Gold Bar mine area as part of a proposed merger with Atlas, and partially drilled out the Millsite deposit. The proposed merger was terminated in 1997. American Barrick (Barrick Gold Exploration Inc.) acquired 90% of the Gold Bar properties in 1997 with a 2-year option to acquire the balance from Atlas. Barrick drilled a series of wide-spaced holes around the perimeter of the Millsite deposit in search of a >5 million ounce gold deposit. Barrick also drilled seven deep holes to the north. The Barrick joint venture was terminated in 1999, after which Vengold (American Bonanza Gold Mining Corp.) leased all of Atlas' holdings in the Roberts Mountains. American Bonanza reduced the size of its claim holdings in 2001 at which time White Knight staked two noncontiguous claim groups of the Gold Bar Horst claim block bordering the remaining claims at Gold Bar on the north and south. White Knight?s claims are in two noncontiguous blocks, covering the northern and southern projections of the ore-hosting horst beyond Bonanza Explorations' claims in the immediate Gold Bar mine area. The depth to bedrock under Quaternary gravels, as indicated by CSAMT and gravity surveys, and drilling, varies from less than 500 feet to greater than 1000 feet. In 2005 American Bonanza Gold Corp.(95%) announced that recent drill results at the Gold Bar Project include 380-395 feet @ 0.019 opt Au (BZGB-2); 630-725 feet @ 0.017 opt Au (BZGB-4); 690-720 feet @ 0.046 opt Au (BZGB-7) and 615-695 feet @ 0.071 opt Au (BZGB-8). In 2006, White Knight Resources Inc. announced that recent drill results at the Gold Pick Project include 117.3-123.4 meters @ 0.033 opt Au (GPQ-11); 123.4-129.5 meters @ 0.031 opt Au (GPQ-12); 155.4-160 meters @ 0.012 opt Au (GPQ-15) and 160-167.6 meters @ 0.083 opt Au (GPQ- 16). (resource = 2,600,000 tons @ 0.063 opt Au) Also in 2006, American Bonanza Gold Corp. announced that based on recent drill results at the Gold Bar Project, resources aggregate 1,622,500 tons @ 0.091 opt Au inferred.

The claims are in two noncontiguous blocks, covering the northern and southern projections of the horst beyond Bonanza Explorations' claims in the immediate Gold Bar mine area. The depth to bedrock under Quarternary gravels, as indicated by CSAMT and gravity surveys, and drilling, varies from less than 500 feet to greater than 1000 feet. the Gold Bar deposit is located on the crest of a NNW-trending horst of Lower Plate Devonian Limestone covered by a thin veneer of Quaternary gravels and Tertiary volcanics. Mineralization is controlled by a NNW-trending fault and structural intersections with NE-trending cross faults. The recently discovered Millsite deposit lies 1000 feet WNW of the Gold Bar Mine and contains about 150,000 ounces gold at a grade of 0.09 opt gold (1.6 million tons @ 0.091 opt gold) at a depth of approximately 500 feet. White Knight's claims border within 2000 feet of the Millsite deposit. The majority of previous drilling on the Gold Bar Horst property is less than 350 feet deep and did not encounter bedrock. One deeper drill hole (BGB37) on White Knight's claims north of the Millsite deposit encountered a mineralized jasperoid grading up to 150 ppb gold from 1160 feet to total depth at 1255 feet. This hole may be peripheral to significant gold mineralization. The target is a large blind Carlin-type deposit hosted in Devonian Denay Formation or underlying McColley Canyon Formation beneath gravel cover and a possible cap of Tertiary volcanics. A cap of Vinini Formation siliciclastics at the Roberts Mountains thrust fault occurs along the west edge of the south Olum block and may also occur in the north part of the north Olum claims, enhancing the potential for a major Carlin-style deposit. NNW to NW-trending horst-bounding faults and crosscutting NE-trending faults are likely feeder structures. The mineralizing structure at Gold Bar has little offset, suggesting that it is not a major structure. The master feeder fault (analogous to Post fault in northern Carlin trend) has not been tested. The Gold Bar deposit may itself be a satellite to the major deposit of the district which remains undiscovered beneath gravel cover, possibly along one of the major horst-bounding faults
Ore(s): A northwesterly-trending fault is the main feeder structure for mineralizing fluids. Wider, thicker, and higher grade portions of the orebody occur at intersections of this main feeder zone with northwest-striking high-angle normal faults. Thin-bedded silty limestones are a lithologic control of gold deposition.
