EPA Moves Forward With Gold King Cleanup

They say gold loves misery and, so far, most would agree that 2020 has been a miserable year. Backing up that old adage, gold prices this month surged above $2,000 per ounce (oz). On a percentage basis, the price of silver actually performed better than gold. The two usually rise and fall in tandem. Silver had been lagging, but it quickly caught up, rising more than 60% to nearly $29/oz. Look for an industry-wide revitalization to begin with precious metals.
As this edition was going to press, which would be the five-year anniversary of the Gold King mine blowout, the U.S. Environmental Protection Agency (EPA) and the state of Utah announced they had reached a settlement. On August 5, 2015, a contractor working for the EPA pierced the seal of a mine portal in South West Colorado and released mine water laden with heavy metals. The catastrophic environmental incident created an orange plume that fouled the waterways from .... read more

Machines That Help Reduce Dilution
The top narrow vein mining solutions on the market offer an increased power-to-weight ratio, lower ownership costs and higher productivity

By Jesse Morton, Technical Writer

Hecla’s San Sebastian silver mine used a handful of techniques to reduce dilution. They used controlled blasting techniques, trench sampling, and relied heavily on geologists in the pit to visually assess the muck and face and pinpoint cutoff grade. “Through the whole project, through to the end, we didn’t exceed 10% on dilution,” Alberto Ramos, senior project engineer, Hecla Mining, said. “It ranged between 3% and 7%.” When it launched underground operations in 2018, it planned on cut-and-fill stoping, with ore extracted by rubber-tired equipment. It tested longhole mining Mines.... read more

Dealing With Data: Cybersecurity in the COVID-19 Era
Working smarter and safer has become an industry creed for employee welfare. Companies should apply the same principles to data management.

By Russell A. Carter, Contributing Editor

“Data” might be the most imprecise word in the language of business, both in terms of meaning and value. For mineral producers, a data item could be anything from a momentary, routine signal from a remote sensor, to a single cell in a vast financial spreadsheet. As for value, how is it measured? Is a gigabyte of drill hole data worth more than a gigabyte sent from a pipeline pressure sensor? Sometimes the actual value of data can only be determined when it’s misused or missing. The cost of ignoring or misinterpreting data from a haul truck temperature..... read more

Pit Dewatering
Dewater, Derisk, Deliver
Dewatering is a vital component of safe, productive mining operations, but its role and impact are often misunderstood

By Carly Leonida, European Editor

The law of gravity dictates that the creation of an open-pit mine — essentially, a giant funnel cut into the earth through layers of rock — will channel and collect water. No matter the scale of an operation, it is inevitable that the excavation will intercept groundwater flows at some point and, depending upon the local conditions, surface water or run-off is also likely to pool in certain areas. Effective dewatering benefits every function within an operation, from mine design and slope stability .... read more
