Harry Moser reports that one of the many surprises coming out of the current, tumultuous presidential election cycle is the degree to which manufacturing has emerged as a significant campaign issue. Candidates are now openly pledging to oppose trade agreements perceived as hurting the U.S. manufacturers. And while trade policy is only one aspect of the overall debate, it is clear that candidates are recognizing the importance of manufacturing to the American economy.

A quick glance at the U.S. industrial landscape tells a profound story ... America has lost more than five million ma... More →

The largest, most significant technological innovations depend on minerals. Take beryllium, for example, which has properties that help advance and improve nearly every modern American industry. In 2015, the U.S. produced 275 tons of beryllium, 92% of the world beryllium resources mined that year. In the U.S., the majority of domestic produced beryllium is found in Utah, but reserves can also be found in Alaska.

Because of its low density, beryllium is lightweight and pliable. In fact, it is lighter than aluminum and stronger than steel, making it perfectly suited for alloys used in... More →

Peter Dasler reports that CanAlaska Uranium Ltd. is pleased to report that it has acquired by staking approximately 75 kimberlite targets in the Western Athabasca Basin, Saskatchewan. The claims staked by CanAlaska cover kimberlite style targets developed from a high-resolution airborne geophysical survey carried out on behalf of the Saskatchewan Geological Survey.

The 2011 airborne magnetic survey reveals a series of discrete magnetic anomalies with a shallow signature northeast of the Carswell structure and close to a large crustal structure, the Grease River Shear Zone. The Sask... More →

Dave Coler reports that one of the key challenges to good XRF sample preparation is contamination. Contamination comes from two main sources ... the sample preparation device and sample to sample cross contamination.

Sample pulverizers are usually the sample preparation device that has the potential to contribute the most contamination to a sample. Pulverizers usually use a ring and puck style grinding bowl to grind samples from coarse chips to a fine powder. This grinding action can add various elements contained in the grinding vessel to a sample which is why one should be careful... More →

William Lewis opines that in his second of a series of articles discussing best(?) practice, we focus on the importance of continuity within a mineral resource. The first article covered the classification of resources. Continuity lies at the heart of that discussion and, from the Lewis view, is one of the most important but one of the most frequently overlooked issues when conducting mineral resource estimates.

The Merriam-Webster online simple definition of continuity(?), as it applies to his discussion, is ... a) the quality of something that does not stop or change as time passe... More →

Dimitri A. Sverjensky and Fang Huang report that diamond formation has typically been attributed to redox reactions during precipitation from fluids or magmas. Either the oxidation of methane or the reduction of carbon dioxide has been suggested, based on simplistic models of deep fluids consisting of mixtures of dissolved neutral gas molecules without consideration of aqueous ions.

The role of pH changes associated with water-silicate rock interactions during diamond formation is unknown. They demonstrate that diamonds could form due to a drop in pH during water-rock interactions.... More →

Micron geologists report that the economic geology of the so called Ring of Fire area in the James Bay lowlands of northern Ontario is centered upon two principal domains, namely the Archaean granite-greenstone terrain with potential for gold, base metals, volcanogenic massive sulphides and diamond deposits, and the younger Ring of Fire layered igneous complex (ROF) with potential for chromite and platinum group elements-nickel-copper (PGE-Ni-Cu) deposits.

This article is restricted to the ROF and focuses on its potential for new discoveries. Backed by the knowledge of its consulta... More →

The analysis of rocks and minerals often require the preparation of thin sections. This involves the laborious task of cutting, bonding and grinding a specimen down to a mere 30 micron. Since the margin for error is low and each specimen has unique physical properties sample preparation is extremely challenging. Struers new SystemAbele accessories solve this problem with revolutionary and patented UV bonding and diamond grinding technologies, which make the production of thin sections fast and easy....

This edition of European Geologist is dedicated to metallic mineral resources, to complement the previous issue, which focused on industrial minerals and construction materials. The majority of the articles now published describe metallic ore deposits in Europe, and this is an interesting consequence of shifting political attitudes that, until recently, were against mining. The opposition to mining and the disinvestment in European mines arose after the 1970s, induced by growing environmental standards and the transfer of mining activities to third world countries. This situation had advantage... More →

This report presents the results of the 2015 annual survey of mining and exploration companies. The survey is an attempt to assess how mineral endowments and public policy factors such as taxation and regulatory uncertainty affect exploration investment. The survey was circulated electronically to over 3,800 individuals between September 15th and November 27th, 2015. Survey responses have been tallied to rank provinces, states, and countries according to the extent that public policy factors encourage or discourage investment. A total of 449 responses were received for the survey, providing su... More →

Boart Longyear Drilling Services reports that as the value of minerals continues to rise in the marketplace, mining companies are revisiting their heap leach pads. A heap leach pad can contain a wealth of minerals that are waiting to be discovered. Boart Longyear Drilling Services was contracted to implement their sonic program to sample and install wells into targeted heap leach pads.

Heap leach pads are large piles of rock waste from a mine operation that receive further processing through a leaching solution to remove the mineral ore from the rock. The leaching solution is applie... More →

Megan Van Wyngaardt reports that the global mineral exploration is in crisis, but mining companies can turn their exploration performance around. Finding orebodies is not all about luck and success is not unpredictable. And while some companies struggle to replace depleted reserves, those that act in a counter cyclical way that build world-class exploration capabilities will be rewarded with disproportionate returns, said The Boston Consulting Group (BCG) partner Alexander Koch, coauthor of a new report by the management consulting firm, titled Tackling the Crisis in Mineral Exploration.

Leger blogs that it occurred to him that there are probably investors and mining individuals who have no idea of US mining law or the history of the government involvement in mining. Over the years, the U.S. mining industry has been restricted in mine development and exploration due to increased government involvement in the form of mineral land withdrawals (wilderness areas), environmental restrictions (sage grouse habitat), added claim holding costs and BLM exploration regulations (5-acre land disturbance).

Spectral Evolution indicates that valuable information to determine the type of alteration of potential deposits an be obtained with oreXpress and EZ-ID software. High sulfidation epithermal deposits are commonly characterized by alteration zones with mineral assemblages dominated by alunite, pyrophyllite, kaolinite, illite, and chlorite rich clays. Detecting and identifying these minerals in the field can provide geologists and the companies they work for, with the accurate data necessary to guide cost-efficient continued sampling and drilling.
