BOYD's reserve reports receive mining industry wide acceptance and comply fully with both foreign and U.S. Securities and Exchange Commission (SEC) filing requirements. We have completed over 2,000 reserve audits. Representatives of BOYD have appeared before SEC’s technical staff to support our estimates. Coal reserve classifications used in BOYD's mining reserve studies and reserve audits are directed toward reliability of the deposit. These classifications assist in future planning of exploration and mining.

• Completed a comprehensive multiple-seam, multiple-mine reserve audit for a major producer in the Republic of South Africa as part of an overall operational assessment. Highly variable coal qualities, igneous intrusions, large volatilized zones, and multiple mining methods were all key considerations in determining reserve estimates. Supplied our client with a series of detailed maps and reserve tabulations.



• Completed an independent reserve audit of a large US coal producer. The demonstrated reserve base of 2.1 billion tons was investigated and encompassed operating and inactive properties in Illinois, Indiana, Kentucky, Tennessee, Utah, West Virginia, and Wyoming.



• Performed an independent reserve audit of a large US coal producer. The demonstrated reserve base of 1.9 billion tons considered surface and underground reserves in Alabama, Colorado, Illinois, Indiana, Kentucky, North Dakota, Texas, Tennessee, Virginia, West Virginia, and Wyoming.
