Rexall

The Rexall is a gold mine located in Alaska.

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.

Mine Info

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.

Comments

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Smith, 1913 (B 525)

Comment (Workings): Workings / Exploration = The Rexall mine was discovered by J.L. Solomon in March, 1910, and shortly afterwards, he staked four claims on the property (Times Publishing Company, 1912). Mining was started on a 3- to 5-foot-wide shear zone oriented N 25 E, 25 NW (Smith, 1913; B 525). By the end of 1911, an adit had been driven 127 feet, and 50 feet of drift cut on a quartz-rich shear zone that varied from 8 to 32 inches wide (Brooks, 1912). By mid-1912, a richer ore shoot was intersected about 140 feet from the portal of the Rexall adit. Work on the larger, northeast-trending shear was abandoned and a winze was sunk to the water table on the smaller, east-west trending shear. A total of 340 feet of drift had been driven on the smaller shear; two winzes and five production stopes were ready for mining by November, 1912. The smaller shear zone was intersected in the main Rexall adit approximately 140 feet below the surface.? In the fall of 1912, a two-stamp Joshua Hendy mill was erected on the Rexall claim and began milling ore in November, 1912. By this time the Rexall adit was 485 feet long and six stopes were ready for mining (Times Publishing Company, 1912).

Comment (Deposit): Model Name = Gold-quartz vein.

Comment (Geology): Geologic Description = Gold is found in quartz-rich shear zones. Mining initially began on a 3- to 5-foot wide shear zone trending N 25 E, 25 NW (Smith, 1913; B 525). Samples collected from the Rexall mine in 1910 averaged 6 ounces of gold per ton. By 1911, an adit had been driven 127 feet and 50 feet of drift had been driven on a quartz-rich shear zone that varied from 8 to 32 inches wide (Brooks, 1912). A richer ore shoot was intersected about 140 feet from the portal of the Rexall adit. This zone contained a 1- to 8-inch-wide quartz-rich shear that trends east-west and dips 60 N. The smaller shear is offset a few feet by the larger shear (Smith, 1913; B 525).? By November, 1912, a total of 340 feet of drift had been driven on the smaller shear and two winzes and five production stopes were ready for mining. The smaller shear zone was intersected in the main Rexall adit approximately 140 feet below the surface. Several custom lots of Rexall ore were milled in Fairbanks during 1912. A 25 ton lot from the small shear averaged $112 per ton in free gold (5.4 ounces of gold per ton); a 10 ton lot from the small shear averaged $166 of gold per ton in free gold (8.0 ounces of gold per ton) and a 3 ton lot from the large shear averaged $37 of gold per ton, or 1.8 ounces of gold per ton (Smith, 1913; B 525).

Comment (Production): Production Notes = Over the winter of 1911-1912, approximately 25-tons of ore were custom milled; they averaged $120 per ton or about 5.8 ounces per ton gold (Times Publishing Company, 1912). Several custom lots of Rexall mine ore were milled in Fairbanks during 1912. A 25 ton lot from the small shear averaged $112 per ton in free gold (5.4 ounces per ton gold), a 10 ton lot from the small shear averaged $166 per ton in free gold (8.0 ounces per ton gold) and a 3 ton lot from the large shear averaged $37 per ton in free gold, or about 1.8 ounces of gold per ton (Smith, 1913; B 525). In the fall of 1912, a two-stamp Joshua Hendy mill was erected on the Rexall claim and began milling ore on November 28, 1912. By this time the Rexall adit was 485 feet long and six stopes were ready for production (Times Publishing Company, 1912). No references to the Rexall mine are available for the period 1913 through 1921. By 1922, Davis (1922) and Stewart (1922) reported that the Rexall mill had been sold to the owners of the David mine and moved to Skoogy Gulch.
