. • • III IIIIIIIIIIIIIIII 999 s~ EXHIBIT B - MINING PLAN Taminco, Inc. Monogram Mines (Union Carbide Lease) July 3, 197E Taminco, Inc. holds a mining lease from Union Carbide Corporation on portions of the Monogram group of claims which it operat~ua-under the name Monogram Mines (Union Carbide lease). The Monogram area has a long history of mining extending back to the early part of the century which has resulted in numerous interconnected and adjacent mine workings. The uranium-vanadium deposits are often small and erratic, varying in depth from surface exposures to several hundred feet depending on the canyon-and-mesa topography typical of the Uravan mineral belt. Past activities have provided most of the access and drill roads, power and telephone lines, waste dumps and surfaces facilities necessary to resume operations. Thesa existing appurtenances will be utilized where feasible in conducting the planned operations. Therefore, additional surface disturbance will be kept to a minimum. The mines were considered essentially worked out until the recent advance in the price of uranium justified yet another round of activity. The current mining program will consist predominately of a series of small cleanup operations with old workings explored and rehabilitated where results justify. The work will involve mostly underground mining, however, some surface mining will be conducted to extract shallow deposits. Ore leads exposed in the existing workings are testholed and/or followed, surface exploratory holes are drilled to search for and delineate new deposits, and venti- lation holes and raises are required to control radon con- centrations in the working areas. IJue to the erratic nature and generally small size of the deposits, flexibility to adjust to developing conditions must be incorporated in the mining program.
