<br />. <br /> <br />. <br /> <br />Testing with procedures, in addition to those outlined in Table I, <br />is planned and will be completed as time permits. <br /> <br />EVALUATION OF FIELD TRIALS <br /> <br />Table III summarizes briefly the results of the evaluations, to date, <br />of field trials at locations as shoun on Map 2. <br /> <br />While the table is essentially self-explanatory, it is very brief <br />(perhaps even fragmentary). Detailed records are being compiled on <br />each of the jobs included in the table. Thus, if add.itional information <br />relating to any particular trial is desired, or if you have additional <br />information to supply for any trial, please write us. <br /> <br />Additional evaluations are planned, both for' the trials in the present <br />table and for new trials or other trials not included in this summary. <br /> <br />DISCUSSION OF RESULTS AND FUTURE PLANS <br /> <br />As mentioned in the two preceding quarterly reports, the objectives of <br />the CSU bentonite project are (a) to inventory the clay resource of <br />Colorado, and (b) to develop methods of utilizing the local clays in <br />sealing canals and reservoirs in Colorado. Thus, the two important <br />justifications for this State-funded work relate to (a) development of <br />new mineral industry, and (b) conservation of water. Thus, while the <br />market potential aspects are not involved directly in many research <br />studies, they are definitely involved in this inventory, research and <br />development project .--organization of the bentonite project work <br />clearly reflects this influence. <br /> <br />Clay inventory--with the valuable assistance of many cooperators <br />(individuals, companies, districts),the initial sampling efforts by the <br />CSU project have revealed a good range of available clay (bentonite?) <br />deposits (See Map I). A8 a result of this, we are convinced (a) that <br />a significant potential of clay deposits is available for development <br />in Colorado, and (b) that the initial sampling efforts as outlined in <br />this report have covered only a small fraction of the total potential. <br />,Because of the magnitude of the clay resource inventory work remaining. <br />to be completed, plans are being made for continUing this work by the <br />CSU Geology Department in the next fiscal year--provided funding is <br />available. The fi.eld work is planned for the summer and the clay <br />mineral identification (including X-ray and D-T analyses) for the <br />winter. Chemical testing of the better clay samples by the CSU Soils <br />Department is also planned. <br /> <br />-2- <br /> <br />, <br />
