SEDIMENT-HOSTED AU DEPOSITS (MODEL 26A; Berger, 1986) By
SEDIMENT-HOSTED AU DEPOSITS (MODEL 26a; Berger, 1986) by Albert H. Hofstra, Joel S. Leventhal, David J. Grimes, and William D. Heran SUMMARY OF RELEVANT GEOLOGIC, GEOENVIRONMENTAL, AND GEOPHYSICAL INFORMATION Carlin-type deposits are epigenetic, large-tonnage, low-grade, sediment-hosted disseminated gold deposits. The deposits are known mainly in northern Nevada and northwestern Utah where they are arranged in clusters and belts. The deposits in this region are estimated to contain about 5,000 tonnes of gold, more than half of which (~3100 tonnes) is in the Carlin Trend. Approximately 1,000 tonnes of gold have been produced. Carlin-type gold deposits are one of the most important types currently being mined in the western United States. Many aspects of this geoenvironmental model also apply to distal disseminated deposits as defined by Cox and Singer (1990), Doebrich and Theodore (in press), and Howe and others (1995). Deposit geology Unoxidized refractory ore: Refractory ore consists of variably decalcified, dedolomitized, argillized, silicified, sulfidized, carbonaceous sedimentary rocks that contain disseminated iron, arsenic, antimony, mercury, and thallium sulfide minerals. Base-metal sulfide minerals are rare or absent in most deposits. Although pyrite, marcasite, orpiment, and realgar have high acid-generating capacity, they generally are present in small amounts (much less than 5 volume percent) and are usually disseminated in, or surrounded by, carbonate rocks with high acid-consuming capacity. Zones with 5-50 volume percent pyrite, marcasite, orpiment, or realgar are present in some deposits. Ore is refractory because much of the gold forms sub-micron grains in pyrite and marcasite and because carbon in the rock can extract gold from cyanide solutions. -

Abuse by Barrick Gold Corporation Barrick's Porgera Gold Mine
FACTSHEET: Abuse by Barrick Gold Corporation Representing survivors of gang rape and those killed by Barrick Gold Corporation’s security guards at the Porgera gold mine in Papua New Guinea Canadian mining company Barrick Gold Corporation, the largest gold mining company in the world, operates the Porgera mine in Papua New Guinea (PNG), where security guards have raped and gang-raped hundreds of local women and girls and killed several local men. EarthRights International (ERI) represents a number of survivors of rape and family members whose relatives were killed by Barrick security guards. Barrick’s Porgera Gold Mine Barrick has owned and operated the Porgera gold mine since 2006, when it acquired the previous owner, Placer Dome. Barrick also acquired a legacy of environmental damage and human rights abuses that it has failed to remedy. Each day, Barrick dumps more than 16,000 tons of waste into the Porgera River and local creeks that villagers have long relied upon for drinking water, bathing, and washing clothes and food. The mine’s ever-expanding waste dumps continue to take over the land and bury the homes of the original landowners that have lived in the region for generations, long before large-scale mining came to Porgera. Surrounded on all sides, villagers have no choice but to cross the dangerous dumps to reach agricultural land, commercial areas, schools or other villages. Many have not been compensated for the loss of their land and their homes, and Barrick has refused to relocate them. Without land to farm and sources of clean water, practically the only means of income available to some of the local indigenous communities is to scavenge for remnants of gold in the open pit or the treacherous waste dumps. -

As of 31 December 2007 the Government Pension Fund – Global held shares worth some NOK 1,274 million in the company. Barrick Gold is a Canadian mining company, which, in several countries, has been accused of causing extensive environmental degradation. The Council has investigated whether riverine tailings disposal from the Porgera mine in Papua New Guinea generates severe environmental damage, and finds it established that the mining operation at Porgera entails considerable pollution. The Council attributes particular importance to the heavy metals contamination, especially from mercury, produced by the tailings. -

NEWS RELEASE TRANSMITTED BY CCNMatthews FOR: VEDRON GOLD INC. SHARES: 25,351,863 TSX VENTURE SYMBOL: YVG OCTOBER 21, 2002 - 09:15 EDT Vedron Gold Inc.: Placer Dome Commences Follow-up Drilling TORONTO, ONTARIO-- Timmins Gold Camp, Timmins, Ontario Vedron Gold Inc. is pleased to announce Placer Dome (CLA) Limited has commenced follow-up drilling on the Buffalo Ankerite property, on which Vedron holds a gold production royalty in the form of a Net Smelter Royalty. The Buffalo Ankerite Property is located directly south of the Fuller Deposit property where Vedron established a 700,000 ounce gold resource during 1996-1998. During April and May of this year Placer completed 23 drill holes on the Buffalo Ankerite property where nearly one million gold ounces were produced from 1926-1974. Placer plans to complete about 25 more drill holes in the current phase of program to confirm the presence of a potentially economic gold zone. The Vedron Fuller Deposit property and the Buffalo Ankerite property are adjacent to the Dome Mine operation, now part of the Porcupine Joint Venture with Kinross Gold, where Placer Dome produces in excess of 300,000 gold ounces per year. Vedron Gold holds the Fuller Deposit property subject to Placer earning their option to acquire the Fuller Deposit property and then making an acquisition payment plus production royalty payments. Vedron holds a 2% NSR on the Buffalo Ankerite property. Vedron recently announced the acquisition a production royalty on the Zenda Mine project in Kern County, California. Vedron Gold is continuing to review further possible royalty purchases. -
Carlin-Type Gold Deposits in Nevada: Critical Geologic Characteristics and Viable Models

MUNTEAN, Nevada Bureau of Mines and Geology, Mail Stop 178, University of Nevada, Reno, Nevada 89557-0088 RICHARD M. TOSDAL, AND KENNETH A. HICKEY Mineral Deposit Research Unit, University of British Columbia, 6339 Stores Road, Vancouver, British Columbia, Canada V6T 1Z4 Abstract Carlin-type Au deposits in Nevada have huge Au endowments that have made the state, and the United States, one of the leading Au producers in the world. Forty years of mining and numerous studies have pro- vided a detailed geologic picture of the deposits, yet a comprehensive and widely accepted genetic model re- mains elusive. The genesis of the deposits has been difficult to determine owing to difficulties in identifying and analyzing the fine-grained, volumetrically minor, and common ore and gangue minerals, and because of postore weathering and oxidation. In addition, other approximately contemporaneous precious metal deposits have overprinted, or are overprinted by, Carlin-type mineralization. Recent geochronological studies have led to a consensus that the Nevada deposits formed ~42 to 36 m.y. ago, and the deposits can now be evaluated in the context of their tectonic setting. Continental rifting and deposi- tion of a passive margin sequence followed by compressional orogenies established a premineral architecture of steeply dipping fluid conduits, shallow, low dipping “traps” and reactive calcareous host rocks. -

Submission to the United Nations Working Group on the Use of Mercenaries
Submission to the United Nations Working Group on the Use of Mercenaries In regard to the relationship between private military and security companies and extractive industry companies from a human rights perspective in law and practice This Submission is in regard to the North Mara Gold Mine in Tanzania and the Porgera Joint Venture Gold Mine in Papua New Guinea. March 2019 Catherine Coumans, Ph.D. Table of contents Introduction p. 1 1. Context p. 2 2. The relationship between the mines’ security, the company and the State p. 6 3. Alleged human rights abuses of the mines’ security forces p. 12 4. International, national, and company-level regulations, p. 15 mechanisms and procedures, and standards 5. Recommendations p. 20 Introduction This submission is made in support of an investigation and forthcoming report by the United Nations Working Group on the Use of Mercenaries (the Working Group)1 that examines the relationship between private military and security companies and extractive industry companies from a human rights perspective. Following communications with the Working Group, this submission covers issues related to excess use of force by private mine security and by police who participate in securing mines through memorandums of understanding between mine proponents and police agencies of the states hosting the mines. The sections below follow organizational and informational guidelines provided by the Working Group.2 This submission highlights that: state security forces deployed with private security often abuse their power in violation of the human rights of local populations; corporate-led monitoring and responsive measures are insufficient both to prevent abuse and to ensure meaningful accountability; greater attention needs to be given to crafting robust remedy mechanisms for those who have been harmed by both public and private security at mine sites; and, international soft law guidance on these issues (e.g.
