Land Status

Land ownership: BLM Administrative Area
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.

Structure

Type: R
Description: The southwestern part of the Kawich Mountain Range has been interpreted to represent a caldera complex. The eastern side of this collapse and resurgent feature is partly preserved on the western flank of the mountain range and the western side of the caldera is buried in the Stone Cabin Valley/Cactus Flats depression. Late Precambrian and early Paleozoic sedimentary rocks form the basement into which the caldera was erupted. This caldera complex is rhyolitic in composition and has an age of 17.8 + 0.5 m.y. (Cornwall, 1972). The Golden Arrow Mining District and Golden Arrow South are situated on the northern margin of the caldera complex but the gold-silver deposits are reported to be hosted in an older rhyolite unit with an age of 21.1 to 21.9 m.y.

Comments

Comment (Geology): The southwestern part of the Kawich Mountain Range has been interpreted to represent a caldera complex. The eastern side of this collapse and resurgent feature is partly preserved on the western flank of the mountain range and the western side of the caldera is buried in the Stone Cabin Valley/Cactus Flats depression. Late Precambrian and early Paleozoic sedimentary rocks form the basement into which the caldera was erupted. This caldera complex is rhyolitic in composition and has an age of 17.8 + 0.5 m.y. (Cornwall, 1972). The Golden Arrow Mining District and Golden Arrow South are situated on the northern margin of the caldera complex but the gold-silver deposits are reported to be hosted in an older rhyolite unit with an age of 21.1 to 21.9 m.y.

Comment (Identification): This mine area encompasses the area described in earlier MRDS record M231953 and adjacent areas. The earlier record should however probably be kept in the database for historical reference.

Comment (Location): The prospect is centered around the old Golden Arrow townsite with activity concentrated about a mile and a half to the southwest.

Comment (Development): The mine was listed as an active heap leach operation in 1980, employing 6 persons. In 1996, Golconda Resources agreed to lease the CNR claims of Mountain View Exploration in the Golden Arrow district where earlier sampling had reportedly outlined a large gold and silver anomaly with rock chip values of up to one ounce per ton of gold and 13 ounces per ton of silver. Also in the Golden Arrow district, Kennecott Exploration confirmed zones of anomalous gold mineralization at the Hidden Hill and Gold Coin Zones of its Golden Arrow deposit. Recent drilling in these zones extended significant mineralization at depth and along trend to the south and west. Previous work on the Golden Arrow deposit had defined a resource of 290,000 to 477,000 ounces of gold and 4.1 to 6.2 million ounces of silver contained in 12.4 million tons grading 0.039 ounces of gold per ton located in two separate zones. In 1997, Tombstone Explorations Co acquired the Golden Arrow project from Kennecott Explorations and commenced RC drilling late in the year. The property consisted of 16 patented and 419 unpatented claims covering the Gold Coin, Confidence, and Hidden Hill deposits. Drilling in 1997 focused on the Hidden Hill deposit and expanded its estimated geologic resource to 3.9 million tons containing 0.034 ounces per ton of gold. Exploration of the property lapsed for a few years, but resumed by 2003, when it was reported that Phase II drilling was underway on Pacific Ridge Exploration Ltd.'s Golden Arrow property. The 2003 Phase II program called for about 25,000 feet of drilling on two high-grade epithermal gold vein feeder systems within the Gold Coin and Hidden Hill zones as well as initial drilling of the large, recently discovered Sunrise target. In 2004, Pacific Ridge Exploration Ltd. completed drilling on its Golden Arrow property and, following study of this and previous drilling, decided to cease work and terminate their agreement on the Golden Arrow property with Nevada Sunrise LLC as the exploration results on the property did not meet Pacific Ridge's corporate objectives In late 2005, Seabridge Gold Inc. announced discovery of a 1,200 meter by 700 meter area of surface gold/silver mineralization on its 100% owned 4,600 acre Golden Arrow project. Golden Arrow was one of two selected for drilling from a portfolio of 12 Nevada exploration projects evaluated by Seabridge geologists in the Company's 2005 Nevada exploration program. A zone of well developed silicic alteration has been identified in the southwest part of the Golden Arrow project. In the vicinity of this alteration zone, 29 rock samples were collected by Seabridge with gold concentrations from trace levels up to 9.95 grams per tonne gold and 246.9 grams per tonne silver. In addition, auger sampling was completed over the zone of silicic alteration and soil geochemical sampling was completed on the strike projection of this alteration zone. A primary target zone defined by alteration and gold geochemistry has an area of about 1,200 meters by 700 meters. A secondary target of 2,000 meters by 500 meters located to the north of the primary target has also been identified but results are indicative of thicker cover in this area. An initial drill program consisting of 2,000 meters of reverse circulation drilling was planned for 2006

Comment (Workings): Older workings consist of a shaft, with more recent surface exploration activity and drilling

Comment (Economic Factors): Previous work on the Golden Arrow deposit had defined a resource of 290,000 to 477,000 ounces of gold and 4.1 to 6.2 million ounces of silver located in two separate areas of the project. 1997 estimated reserves were 12.4 million tons of material grading 0.039 ounces of gold per ton. No 2005 reserves or resources were listed.

Comment (Commodity): Ore Materials: silver minerals, native gold, sphalerite

Comment (Commodity): Gangue Materials: gangue minerals: pyrite, quartz, calcite, adularia

Comment (Deposit): Gold-silver mineralization is associated with north-northwest-trending, quartz-after-calcite sheeted veins and stockwork zones in silicified rhyolite. Exploration work confirmed two high-grade epithermal gold vein feeder systems within the Gold Coin and Hidden Hill zones as well as another large mineralized target, Sunrise. Seabridge identified a zone of well developed silicic alteration in the southwest part of the Golden Arrow project. In the vicinity of this alteration zone, 29 rock samples were collected by Seabridge with gold concentrations from trace levels up to 9.95 grams per tonne gold and 246.9 grams per tonne silver. In addition, auger sampling was completed over the zone of silicic alteration and soil geochemical sampling was completed on the strike projection of this alteration zone. A primary target zone defined by alteration and gold geochemistry has an area of about 1,200 meters by 700 meters. A secondary target of 2,000 meters by 500 meters located to the north of the primary target has also been identified but results are indicative of thicker cover in this area. The delineated resources in the Golden Arrow Mining District are associated with intense silicic alteration in rhyolite tuff. Silicic alteration is manifested as pervasive quartz introduction in the volcanic rock, stockwork quartz veinlets and quartz veins ranging from a few centimeters to a meter wide. Accompanying the introduction of silica is adularia and minor pyrite. The resources are located at the intersection of north-northwest and east-west trending structures that locally control larger quartz veins.
