Geochemical sampling of mining claims in northern Nevada, as part of an evaluation of their gold potential.

Iron-ore mine in the Mojave Desert. The appraisal required estimating the remaining resource, production costs, and market prices.

Haul truck at a sand and gravel quarry in Riverside County, California. This quarry was appraised for purposes of collateralizing a loan for new equipment.

Engraved corner stone from 1901 mineral survey. Diligent searching allowed us to locate all four corners of this patented lode claim, the location of which turned out to be different from that believed by the owner, and from that shown on BLM maps.

 

Mineral Property Appraisers

Western Mineral Appraisers LLC, and its predecessor Alderman, Slothower & Associates, (AS&A) are in the specialized business of appraising non-fuel mineral rights and mineral properties, and related processing facilities. Appraisals have been undertaken in most of the Western United States, and in several Latin-American countries.

We do not appraise real estate (surface rights only). Also we do not appraise properties for their value in petroleum, natural gas, coal, or oil shale.

Appraisals are undertaken to fulfill various client needs, including acquisitions, property exchanges, mergers, condemnations, estate settlements, project financing, and securities registration. The subject mineral properties include operating mines, patented and unpatented mining claims, homesteads, land grants, railroad lands, state sections, and unappropriated public domain lands. The mineral-rights ownership may or may not be severed from the surface estate.

We use the Uniform Standards of Professional Appraisal Practice (USPAP) and mineral appraisal procedures accepted by the Mining Industry and Government Agencies for determining the Market Value of mineral properties in all stages of development. We also use the Uniform Appraisal Standards for Federal Land Aquisitions (UASFLA) for acquisitions by the federal government. All appraisals are done within the context of the American Institute of Minerals Appraisers Code of Ethics.

Western Mineral Appraisers has extensive experience in using discounted cash-flow analysis as part of the income approach for evaluating proposed mining projects and operating mines.

Our Mining Geologists evaluate ore reserves using recognized industry-standard methods to check computer generated data, to ensure that the geological model is appropriate, and that geologic controls are recognized. Sampling methods are reviewed critically to assure that the input data are realistic. When required, we utilize the services of associated specialists in related fields such as Geostatistics, Mineral Processing, Mineral Marketing, Mining Law, and Environment.
