Approximately 500 acres of patented mining claims and 1,500 acres of unpatented claims on National Forest System lands are involved. A large portion of the project site is impacted by historic mining operations. Some historic impacts have been previously remediated, and Midas Gold proposes to reclaim and/or remediate other legacy mining impacts in addition to the impacts of their operation. The Plan of Operations includes the following: mining from two historic pits and one new open pit to recover gold, silver and antimony; reprocessing of historic tailings; back-filling of one pit; reconstruction of stream channels and wetlands, and restoring fish passage in the East Fork of the South Fork of the Salmon River through the legacy Yellow Pine pit. The company is estimating a project life of approximately 21-28 years, including redevelopment and construction (2-3 years), mining and processing (12-15 years), initial closure and reclamation (2-3 years), and post-closure and monitoring (5-7 years). Preliminary issues identified include access and transportation; fisheries, wildlife, and threatened and endangered species; surface and groundwater; post-closure site management and land use; cultural and historic resources, including Tribal treaty and trust responsibilities; public health and safety; recreation; Roadless and Wilderness resources; and socioeconomics. Project-specific Forest Plan amendments will be required in order to approve the Plan of Operations. Cooperating agencies are the Environmental Protection Agency, the Army Corps of Engineers, and the Idaho Departments of Lands, Environmental Quality, and the Governor’s Office of Energy and Mineral Resources, and Valley County. A third-party contractor, AECOM, has been hired to prepare the Project Area. Existing West End pit in the bottom right, and The EIS.

The Mining District is officially on the Boise National Forest, but the area is administered by the Payette National Forest. The mine is located 35 air miles east of McCall, Idaho. Access to the site is via three routes. In the summer, the Lick Creek and Johnson Creek roads are the primary routes. During winter months, only the South Fork of the Salmon River route is accessible due to snow levels. These routes lead to the community of Yellow Pine, then to the Stibnite Mining District along 12 miles of the East Fork Road. Driving time from McCall to the project site is approximately three hours depending on route taken.

From 1941 to 1945 Stibnite mined and milled more tungsten and antimony than any other mine in the United States. During this wartime period, Stibnite produced 40 percent of the nation's domestic supply of tungsten and 90 percent of its antimony. Following the closing of the mine in the mid- 1950s, additional mining occurred on small and large scale from the 1970s through the Stibnite Mining District in the late 1940s. late 1990s.

In 1991, a release of arsenic was discovered Miners first came to Stibnite during Idaho’s gold rush due to an analysis of steelhead trout taken days in 1899. Over the next few years, the number of from the East Fork of the South Fork miners at the site continued to grow and several Salmon River was discovered. The site operators, including United Mercury Mining Company includes a number of waste source areas and Bradley Mining Company, started working in the resulting from mining along Meadow Creek area. In 1938, miners started focusing their efforts on and the East Fork of the South Fork of the the Yellow Pine Pit, where they were able to extract Salmon River. large quantities of gold from this area of the site. These operations at the pit blocked fish passage and to this day, fish in the East Fork of the South Fork of the Salmon River cannot swim upstream past the site. During World War II, antimony became a mineral critical to the war effort as it was used to create ammunition. Stibnite contained such large quantities of antimony that individuals were able to serve their country by working at the site. At one point, more Stibnite housing in the 1940s. 5 Exploration on the Payette National Forest: Who is Midas Gold Beginning in 2007, Niagara Resources began (Text provided acquiring, through purchase from prior owners or by Midas Gold by staking on its own behalf, mining claims Idaho) throughout the District.

  • Antimony Data Sheet
    22 ANTIMONY (Data in metric tons of antimony content unless otherwise noted) Domestic Production and Use: In 2019, no marketable antimony was mined in the United States. A mine in Nevada that had extracted about 800 tons of stibnite ore from 2013 through 2014 was placed on care-and-maintenance status in 2015 and had no reported production in 2019. Primary antimony metal and oxide were produced by one company in Montana using imported feedstock. Secondary antimony production was derived mostly from antimonial lead recovered from spent lead-acid batteries. The estimated value of secondary antimony produced in 2019, based on the average New York dealer price for antimony, was about $34 million. Recycling supplied about 14% of estimated domestic consumption, and the remainder came mostly from imports. The value of antimony consumption in 2019, based on the average New York dealer price, was about $234 million. The estimated distribution of domestic primary antimony consumption was as follows: nonmetal products, including ceramics and glass and rubber products, 22%; flame retardants, 40%; and metal products, including antimonial lead and ammunition, 39%.

    Itmd1//8Lhmdq`knesgdLnmsg9Rshamhsd This month’s mineral is among the most collectible of all minerals. Ours come from a Chinese antimony mine that is now recognized as a classic stibnite locality, and our write-up explains the unusual structure and properties of stibnite, describes its remarkable crystals, and details the many uses of antimony. OVERVIEW PHYSICAL PROPERTIES Chemistry: Sb2S3 Antimony Trisulfide, often containing some bismuth Class: Sulfides Group: Stibnite Crystal System: Orthorhombic Crystal Habits: Individual bladed or acicular prisms or jumbled aggregates of prisms, striated lengthwise; prisms often bent or twisted; also as radiated groups and granular and massive forms. Color: Lead-gray and gray-black to steel-gray and silvery-gray, sometimes with a bluish hue; occasionally iridescent; tarnish black. Luster: Metallic Transparency: Opaque Streak: Dark lead-gray Refractive Index: None (opaque) Cleavage: Perfect in one direction lengthwise Figure 1. Stibnite crytals. Fracture: Subconchoidal to irregular; brittle; thin prisms are slightly flexible. Hardness: 2.0 Specific Gravity: 4.6 Luminescence: None Distinctive Features and Tests: Best field identification features are softness; flexibility of thin prisms; and long, bladed and acicular crystal habits. Visually similar to bismuthinite [bismuth trisulfide, Bi2S3], which has considerably more density. Dana Classification Number: 2.11.2.1 NAME Stibnite, pronounced STIBB-nite, derives from stibi, the Greek name for the mineral. Stibnite has formerly been referred to as “antimonite,” “antimonide,” “sulfur antimonide,” “sulfur antimony,” “antimony glance,” “gray antimony,” “gray antimony ore,” “kohl,” “stibi,” “stimmi,” “stibium,” “lupus metallorum,” “platyophthalmite,” and “speissglas.” In current European mineralogical literature, stibnite appears as stibnit, stibnita, and stibnine. Antimony, pronounced ANN-tih-mow-nee, stems from the Latin word for the metal, antimonium, which means “opposed to solitude,” in allusion to its rare occurrence as a native element.

  • Minerals of Bismuthinite-Stibnite Series with Special Reference to Horobetsuite from the Horobetsu Mine, Hokkaido, Japan*
    MINERALOGICAL JOURNAL VOL . 1, No. 4, pp. 189-197, JUNE, 1955 MINERALS OF BISMUTHINITE-STIBNITE SERIES WITH SPECIAL REFERENCE TO HOROBETSUITE FROM THE HOROBETSU MINE, HOKKAIDO, JAPAN* KITARO HAYASE Institute of Mining, Faculty of Science and Engineering , Waseda University. ABSTRACT Horobetsuite occurs associated with free sulphur and iron sulphide minerals, in the sulphur deposit of Horobetsu Mine. The chemical formula of horobetsuite has been determined as (Bi, Sb)2S3. The molecular ratio of Bi2S3 to Sb2S3 varies between 9:11 and 13:7. The mineral is intermediate between bismuthinite and stibnite in lattice constant, specific gravity, optical behaviour and etching reac tion. The data obtained reveal the mineral to be a new species belonging to the bismuthinite-stibnite series. A new mineral name, horobetsuite, is proposed for the mineral of the series which should have the molecular ratio of Bi2S3 to Sb2S3 between 7:3 and 3:7. Introduction The writer1) once reported the results of the study of a Bi-Sb sul phide mineral that occurred at the Horobetsu mine, and suggested that it might represent a solid solution of bismuthinite and stibnite. The slight fluctuation observed of the molecular ratio of Bi2S3 to Sb2S3 has prompt us to a further study. Occurrence of horobetsuitel) The Horobetsu mine in which horobetsuite occurs is located at Sobetsu Village, Usu County, in the vicinity of Muroran, Hokkaido, Japan.

PO Box 429 13181 Hwy 55 December 2020 Donnelly, ID 83615 STIBNITE GOLD PROJECT REFINED PROPOSED ACTION – MODPRO2 Summary This document describes Midas Gold Idaho, Inc.’s (Midas Gold’s) proposed further refinements of the Stibnite Gold Project (SGP) Plan of Restoration and Operations (PRO) (Midas Gold, 2016) and presents Midas Gold’s updated proposed action, the ModPRO21. The ModPRO2 was developed to further reduce potential environmental impacts of the SGP in alignment with Midas Gold’s Core Values as set out in the PRO (Section 2), Conservation Principles (PRO Section 2), its Sustainability Goals (PRO Section 2.4) and its Environmental Goals (PRO Section 6.2). Project refinements included in the ModPRO2: (1) are supported by udpated data and analysis that identify opportunities to reduce potential environmental impacts; (2) address persistent potential environmental impacts not sufficiently ameliorated or reduced by project refinements included in the original ModPRO; (3) are informed by public and reviewing agencies’ comments on the DEIS, and; (4) align with the National Environmental Policy Act (NEPA) and all applicable Federal, State and Local regulations and permit requirements. The ModPRO2 also aligns with the project development approach in Midas Gold’s Feasibility Study (FS) (M3, 2020). The ModPRO2 is presented in three sections and an appendix: • Section 1 describes the evolution of the ModPRO2 in the context of the original proposed action (the PRO) and alternatives evaluated in the SGP Draft Environmental Impact Statement (DEIS) including the ModPRO (DEIS Alternative 2). • Section 2 provides the justification and approach for refinements to components of the SGP that result in the ModPRO2.

  • 10800 Realgar
    10800 Realgar Chemical composition : As4S4 C.I. 77085, Pigment Yellow 39 Realgar is the natural orange-red sulphide of arsenic. It is closely related chemically and associated in nature with orpiment. The two minerals are often found in the same deposits. Realgar occurs as a minor constituent in certain ore veins associated with orpiment and other arsenic minerals, with stibnite, lead, gold and silver. It is found in Romania, the former Czechoslovakia, and the former Yugoslavia, Greece, Germany, Italy, Corsica and the western United States. The name is derived from the Arabic rahj al ghar, powder of the mine. The Latin term was sandarach and De Mayerne who was writing in the seventeenth-century referred to it as rubis d'orpiment. Realgar has been found on a few works by Tintoretto and from Bulgarian icons dating from the Middle Ages to the Renaissance. Realgar has also been reported on Indian sixteenth- to seventeenth-century paintings and an eleventh- to thirteenth-century manuscript from Central Asia. Realgar appears to be less permanent and is known to change to orpiment after long exposure to light. Chinese realgar figurines from the eighteenth-century had oxidized to orpiment and arsenious oxide (Daniels). The chemical and physical properties are similar to orpiment. It belongs to the same crystal system (monoclinic). Its color is orange or an orange-red by transmitted light but usually many yellow particles of orpiment can also be seen. The particles of mineral realgar are usually granular, coarse to fine and have a resinous to greasy luster.

  • STIBNITE-QUARTZ DEPOSITS (MODELS 27D,E and 36C; Bliss and Orris, 1986A-C; Berger, 1993)
    STIBNITE-QUARTZ DEPOSITS (MODELS 27d,e and 36c; Bliss and Orris, 1986a-c; Berger, 1993) by Robert R. Seal, II, James D. Bliss, and David L. Campbell SUMMARY OF RELEVANT GEOLOGIC, GEOENVIRONMENTAL, AND GEOPHYSICAL INFORMATION Deposits described in this model are designated "Stibnite-quartz deposits" to describe a group of antimony deposits that share many of the characteristics of simple (vein dominated) antimony deposits (Model 27d; Bliss and Orris, 1986a,b), disseminated antimony deposits (Model 27e; Bliss and Orris, 1986c), and gold-antimony deposits (Model 36c; Berger, 1993), but have features that distinguish them from these models. The Lake George deposit (New Brunswick, Canada) is included in the "stibnite-quartz deposit" geoenvironmental model. However, it was also included by Bliss and Orris (1986a) in their simple antimony (27d) and disseminated antimony (27e) models. The most significant distinction between stibnite-quartz deposits and simple antimony and disseminated antimony models is the lack of an association with volcanic rocks and a minimal association with intrusive rocks. Stibnite-quartz deposits are hosted dominantly by shale, marl, and carbonate rocks (±quartzite and granite) or their low-grade metamorphic (greenschist facies) equivalents, whereas many gold-antimony deposits are associated with mafic and ultramafic metavolcanic rocks. Stibnite-quartz deposits are most similar to those gold-antimony deposits that are hosted by Late Proterozoic turbiditic black shale, siltstone, sandstone, and carbonate rocks; however, gold grades of the stibnite-quartz deposits are distinctly lower than those of the gold-antimony deposits. Gold has been identified in the Lake George (New Brunswick, Canada) stibnite-quartz deposit, but it is present in a minor vein set (Seal and others, 1988) and has not been extracted during mining and milling of the ore.
