Diagrams showing influence of rock character (A) and structural features (B) on ore <br />shoots within veins and vein zones (from Eckel, 1949) <br />MINERALIZATION <br />• <br />The styles of precious metal mineralization encountered in the May Day and <br />Idaho mines have been summarized above. Three styles of mineralization are <br />distinguished: epithermal gold - silver - telluride veins, limestone replacement <br />deposits, and disseminated mineralization in porphyry. All three styles formed at <br />the same time from the same mineralizing ore solutions. The differences in style <br />are a consequence of differences in the physical and chemical properties of the <br />host rock. <br />The potential vertical range of the ore deposits is not known. The main orebody <br />on the May Day vein extended to a depth of 450 feet below the surface, the <br />greatest vertical range of any single ore shoot in the district. The overall vertical <br />range of all ore shoots in this and the adjacent Idaho mine, exceeds 1,250 feet. <br />As far as can be ascertained, there is no significant change in the character of <br />the ore from the highest to lowest ores in the deposits, and there is no indication <br />that the ores do not continue to greater depths, or laterally beyond the limits of <br />current mining and exploration. <br />January 2007 <br />May Day — Idaho Mine Colorado <br />
