Geological Setting, Classification, Genesis and Exploration A REVIEW OF THE SEDIMENT-HOSTED, DISSEMINATED PRECIOUS METAL DEPOSITS OF NEVADA : Geological Setting, Classification, Genesis and Exploration by Philip J Ash Dissertation submitted in partial fulfilment of the requirements for the degree of Master of Science (Mineral Exp loration) , Rhodes University, Grahamstown, South Africa January, 1986 This dissertation was prepared in accordance with specifications laid down by the University and was completed within a period of eight weeks full-time study. ABSTRACT Carlin-type, fine-grained, "invisible" or Disseminated Replacement Type gold­ silver deposits are all different names for a major new type of are deposit that is currently being extensively developed in the Western United States. This type of deposit is now being found elsewhere. Thus a descriptive empirical model that emphasizes the geological and geochemical environment of formation is needed to assist the mining industry in the search for similar deposits. These deposits are typically formed in carbonaceous, silty dolomites and I imestones or calcareous siltstones and claystones. Gold-silver mineralization is disseminated in the host sedimentary rocks and is exceedingly fine-grained, usually less than one micron in size in unoxidized ore. Primary alteration types include decalcification, argillitization, silicification and pyritization. Silicification is commonly intense resulting in the formation of jasperoid bodies which may be the host to higher grade ore. Supergene alteration is dominated by oxidation resulting in the formation of numerous oxides and sulphates and the release of gold from its association with sulphides and organic carbon. Commonly associated trace elements are As, Ba, Hg, Sb, and TI. Available geological, geochemical, fluid inclusion and stable-isotope studies lead to the conclusion that a circulating hydrothermal system is the important factor necessary for gold-silver concentration and deposition. A direct genetic or only casual relation between are deposition and discrete igneous formations remains unclear. However, it is considered that volcanism provided the source of heat necessary for the generation of a circulating hydrothermal system. High angle faults and fold structures facilitate transport and are of prime importance in directing are fluids to favourable host lithologies. The host rocks, overwhelmingly carbonate - rich, include those whose original and/or altered compositions and resulting permeability provide favourable sites for the precipitation of disseminated gold. The processes resulting in the formation of these deposits are not specialized. Any th ick section of carbonate rocks has the potential to produce Disseminated Replacement Type deposits wherever underlying igneous activity has developed a hydrothermal system. CONTENTS PAGE 1 .

Buy Corporate Overview Golden Odyssey Mining Inc. was founded in April 2004, launched its initial public offering in December 2004 and its shares began trading in January 2005. Golden Odyssey Mining—through its wholly owned subsidiary, Golden Odyssey Exploration Inc.—is engaged in the identification, evaluation, acquisition and development of high potential mineral properties in the State of Nevada. Golden Odyssey’s management has extensive experience in the discovery and develop- ment of economically viable gold deposits and the building of strong, well funded mining companies. The Company’s project portfolio is dynamic and evolving with a focus on near-term discovery of world class gold depos- its. Golden Odyssey currently has five active projects—all situated on major gold trends. On the Walker Lane Belt in Es- meralda County, Nevada, the Company has the Morningstar and Palmetto projects. (This highly mineralized trend has hosted some of the most important mining districts in North America including the famous Comstock, Tonopah, Gold- field, Bullfrog and Aurora districts. The region is currently being actively explored by Barrick Gold/Kinross Gold at the Round Mountain Mine, Gryphon Gold at the Borealis Mine, and Newcrest at the Redlich project.) In the Cortez Trend in Eureka County, the Company holds the Anchor and JDS projects, which is situated on trend with Barrick Gold Corpora- tion’s East Archimedes mine and US Gold Corporation’s Tonkin Springs Mine. On the Carlin Trend in Elko County, the Company is exploring the Mexican Hill project which is southeast of Newmont Gold’s Rain and Emigrant Springs mines.

    NEWS RELEASE NYSE: NEM newmont.com Barrick and Newmont Forge Nevada Joint Venture Agreement Historic joint venture designed to unlock $5 billion1 in synergies Barrick to be Operator Ownership to be 61.5% Barrick; 38.5% Newmont Board representation based on ownership Advisory committees to have equal representation Barrick to withdraw Newmont acquisition and AGM proposals ELKO, Nevada — March 11, 2019 — Barrick Gold Corporation (NYSE:GOLD)(TSX:ABX) (Barrick) and Newmont Mining Corporation (NYSE:NEM) (Newmont) said today that the two companies have signed an implementation agreement to create a joint venture combining their respective mining operations, assets, reserves, and talent in Nevada. The joint venture is an historic accord between the two gold mining companies, which have operated independently in Nevada for decades, but have previously been unable to agree terms for cooperation. The joint venture will allow them to capture an estimated $500 million in average annual pre-tax synergies in the first five full years of the combination, which is projected to total $5 billion pre- tax net present value1 over a 20-year period. Barrick President and Chief Executive Officer Mark Bristow said the agreement marked the successful culmination of a deal that had been more than 20 years in the making. “We listened to our shareholders and agreed with them that this was the best way to realize the enormous potential of the Nevada goldfields’ unequalled mineral endowment, and to maximize the returns from our operations there. We are finally taking down the fences to operate Nevada as a single entity in order to deliver full value to both sets of shareholders, as well as to all our stakeholders in the state, by securing the long-term future of gold mining in Nevada,” he said.

This vast deposit of silver in the vicinity of Virginia City, Nevada, was, in fact, responsible for Nevada's separate existence as a sovereign state. As H. H. Bancroft observed: Nowhere else in the world do we find a society springing up in a desert wilderness, so wholly dependent on a mountain of metal, so ruled by the everchanging vagaries of its development, and which finally attained the full measure of a prosperous commonwealth * * *.

  • Humboldt River Chronology an Overview and Chronological History of the Humboldt River and Related Water Issues
    Humboldt River Chronology An Overview and Chronological History of the Humboldt River and Related Water Issues The information contained in Volume 1, Part I – Overview of this Humboldt River Chronology provides a general overview and description of the Humboldt River Basin and Humboldt River and its physical, geologic, and hydrologic characteristics and attributes. Volume 2, Part II – Pre-Twentieth Century and Part III – Twentieth and Twenty-First Centuries contain a detailed listing by date of some of the more important events associated with the Humboldt River Basin, the Humboldt River, sub-basins and various tributaries, storage reservoirs, water diversions, and related water supply, water use, water rights, water resources development, fisheries and habitat, and environmental and water quality issues. Part I – Overview Introduction The Humboldt River Basin is an extensive river drainage system located in north-central Nevada and extending in a generally east-to-west direction from its headwaters in the Jarbidge, Independence and Ruby Mountains in Elko County, to its terminus in the Humboldt Sink, approximately 225 miles away in the desert of northwest Churchill County. The basin encompasses an area of approximately 16,840 square miles and is the only major river system wholly contained within the State of Nevada. Connecting the Humboldt River’s lofty mountain sources of water to the basin’s terminus is the 310- mile long Humboldt River, which, by some claims, is actually about twice that in length accounting for its countless meanders.1 One particularly interesting observation in a U.S. Army Corps of Engineers report’s background study dealt with the meandering flow of the Humboldt River.
