Construction of a computerized model to estimate mineral resources is a common practice in mineral exploration projects and mining operations. Many times a technical report is done as per international reporting standards such as NI-43-101 or JORC to meet the requirement of certain stock exchanges in the world. In all these standards, there are certain minimum suggested requirements that have to be met for reporting mineral resources and reserves. The standards are not and cannot be prescriptive.
Following the release of a USGS report on 23 mineral commodities that are critical for the U.S. economy and security, President Donald Trump signed an executive order to reduce America's dependence on foreign sources of critical minerals. Shortly after the executive order, Interior Secretary Ryan Zinke released a secretarial order on December 21 directing the initial steps to producing a nationwide geological and topographical survey of the U.S.
On December 12, the House Subcommittee on Energy and Mineral Resources held an oversight hearing, “Examining Consequences of America’s Growing Dependence on Foreign Minerals,” to discuss reasons for the declining self-sufficiency of the United States for mineral commodities, and the consequences of relying on foreign sources for critical minerals.
No country in the world produces all of the mineral resources necessary for modern society. International trade plays a critical role in providing these raw materials, forming a global network of production, export, import, and use. This network must continuously adapt to national and international developments in science, technology, politics, and economics. As a result, information on the global flow of raw materials plays a fundamental role in improving national and international resilience to potential supply disruptions and market changes.
The Kentucky Mine Mapping Information System is produced by the Kentucky Energy and Environment Cabinet to allow users to access maps of coal mines and mined out areas in Kentucky. Users can search by company name, seam name, or state file number (SFN). For each map, overview information is provided where available (map year, mine status, mine owner, mine type, seam thickness, etc.), and users are directed to the map. Users can also overlay information on oil and gas activity on the map.
The Minnesota Department of Natural Resources provides an interactive map of underground mines in Minnesota. The map provides detailed information on underground mines and their relationship to overlying surface features. Specifically, this map focuses on iron mines in the northeast of the state.
