Written by: JP George, Business Manager The U.S. Dept of Energy (DOE) classifies critical materials and minerals based on their importance to energy and supply risk. With the new U.S. administration taking office in January 2025, there has been a renewed effort to focus on strengthening the supply of these resources both domestically and abroad. Strengthening Domestic Supply Bipartisan efforts continue to bolster domestic mineral production through legislative actions, such as the proposed Critical Mineral Consistency Act of 2025 and revisions to the Energy Act of 2020. The National Mining Association (NMA) supports these measures, emphasizing the need for U.S. production over reliance on foreign sources. According to the U.S. Geological Survey’s (USGS) 2025 Mineral Commodity Summaries, the U.S. remains import-reliant for many critical minerals, with China controlling production for over two-thirds of these resources. NMA President & CEO Rich Nolan states, “We could be producing most of these minerals here at home—under world-leading environmental, labor and safety standards”. Projects like Perpetua Resources’ Idaho gold project could supply up to 35% of the U.S. annual demand for antimony, demonstrating the potential for revitalized domestic mining.

The Market for Lightweight Construction Mats
Written by William G. Handlos, P.E. Lightweight Construction Mats Construction access in soft soils present a common challenge engineers and project managers face while attempting to complete a project on-time and within budget while avoiding scheduling delays and associated costs. These soft soil sites may also be located in remote, difficult to access areas making construction impossible without a good site access system. Popular construction mat systems are made out of a range of materials including timber, laminate, steel and composite mats. They can be effective, but are also costly. They can also put laborers at risk as they require heavy equipment to install. The ideal mat system for access road construction would be designed to have a high utility-to-weight ratio and would deliver an eco-friendly alternative to current technology. A lightweight construction mat system made from high density polyethylene (HDPE), GEOTERRA®, was created by Presto Products in 2003 to meet the needs of major oil and gas companies working in remote areas of the Amazon jungle. Transporting materials to these sites by helicopter precipitated the need for light, yet strong mats for work platforms and roadways. As the first of its kind, the mats capitalize on the sustainable characteristics of… Read more »
