Since gypsum is a relatively insoluble material, the acid produced by the
oxidation of pyrite would be effectively neutralized.
The contribution of organic sulfur to acidity is considered negligible since
organic sulfur is only slowly oxidized from the organic form to the sulfate form
and may be tied up in other organic forms almost immediately. Since no
inorganic sulfate exists in these drill hole samples, it too may be disregarded
with respect to acidity concerns.
Two drill holes from the B -2 Seam were cored and analyzed for forms of
sulfur. See Exhibit 6 for a tabulation of the laboratory reports and the
locations of the drill holes. The results of the analysis follows:

The results of the geochemical analyses presented below indicates, by its
acid base potential, the B -Seam coal is not acid producing.
A sample of run of mine coal, from the nearby Bowie No. 1 Mine, was
analyzed to determine if the coal has sufficient lime to neutralize its acid
producing characteristics. The coal mined from the Bowie No. 1 Mine has a
carbonate equivalent of 0.22% which equates to 4.4 pounds per ton of coal
or 4,400 pounds of lime per 1,000 tons of coal. This means the coal
contains adequate lime to neutralize coal bearing 0.07% iron pyrite (4,400
divided by 625). The laboratory report is presented in Volume III, Exhibit 6.
