SENT BY:FSP&T, LLC, U2 ;11-20- 1 ~ 7:31AM <br />b <br />GEOCHEMCSTRY & ANALYTICAL RESULTS <br />• Intelpietatiotls 1[t t}tis section aze divided into eight brief statements, grouped into <br />four sets: one evaluation for limestones and one for averaged shale interbeds. All data <br />referred to are provided in the,Appendix. Analyses provided by CT&E for Fort Hays <br />Member li[hofacies indicate: <br />l•) limestone beds average U.OS (Wt. %, dry) of elemental sulfur, both as sulfide minerals <br />(e.g. pyrimj and sulfates (e. g, gypsum); <br />2.) averaged sulfur values for shale interbeds are 0.07 (f): higher than the limestones, but <br />still less than one-tenth of one percent. <br />- These values rank in the lower 20% (in terms of sulfur content) of calcium carbonate <br />deposiu presently used as acement-producing resource. Rank' excellent <br />3.) limestone beds average < 0.10 % (by weight) of kerogens and organic cazbon: <br />4.) averaged kerogen values For shale interbeds aze only slightly higher (-0.2 %). <br />• These values cask in the lower 20% (in terms of kerogenlTOC con[enQ of calcium <br />cazbonate deposits presently used as acement-producing resotuce. Rank: excellent <br />5.) regarding ammonium nitrate (NH3), limestone beds average QS micrograms per <br />gram (µg/g), well below any reasonable limit for potential formation of ammonia <br />compounds upon roasting of limestone; <br />6.) surprisingly, NHS values for shale interbeds are comparable to those of limestones, <br />• attesting to the overall purity of the Fort Hays Member lithologies on the property. <br />• These values rank In the lower 20% (in terrors of ammonium nitrate content) of calcium <br />carbonate deposits presently used as a cement-producing resource. Rank: excellent <br />7.) percentages of silica and alumina (essential far cement production) in limestones aze <br />quite low {~7,0 "/o and 1.35 %, respectively), owing to the >45 % of CaCby composition <br />of These marine cazbonate micrites; <br />g.) averaged silica (SiOz) values for shale interbeds = 28.0% (3) <br />and avg. alumina (A1Z03) values for shale interbeds = 9.0% (t). Rank: very good <br />All CT&E laboratory analyses from cores #1101 to 1107 are listed in the appendix. <br />• 1998 <br />
