Introduction <br />This manual provides a detailed description of the ore control <br />process that is used at the San Luis Mine. Ore control is the <br />method that is used to identify and mine the highest-quality ore <br />for milling. <br />Ore control is the responsibility of the Mine Geologist, but <br />requires close teamwork and cooperation between Mine and Mill <br />operations, and other groups in Technical Services. <br />II. Summary <br />Ore control steps are listed' below, showing th~=_ areas or <br />departments that are most directly involved in each seep: <br />1. <br />2. <br />3. <br />4. <br />5. <br />6. <br />7. <br />8. <br />9. <br />10. <br />11. <br />1<. <br />1?. <br />1~. <br />1~. <br />crest/toe stakeout <br />blasthole pattern layout <br />drilling/sampling/delivery <br />blasthole survey <br />blasthole sample assay <br />assay bench plots <br />ore perimeter development <br />mining or mucking maps <br />blasting <br />ore perimeter flagging <br />elevation control <br />mining <br />stockpiling <br />mill feed and blending <br />check samples <br />Mine Engineering, Tech <br />Drill Foreman, Mi:ie Ops <br />Drill Operators, 1Qine Ops <br />Mine Engineering, Tech. <br />Analytical, Tech. <br />Mine Engineering, Tech. <br />Mine Engineering, Tech. <br />Mine Engineering, Tech. <br />Blasting Foreman, Mine Ops <br />Mine Engineering, Tech. <br />Mine Ops, Tech. <br />Mine Ops and Mine Geology <br />Mine Ops and Mine Geology <br />Mine Geology and Piill Ops <br />Mine Geology, Tech. <br />Steps are generally listed in order of completion. Some steps may <br />overlap ;~rith others. Detail descriptions of each ste~~ follow. <br />III. Procedures <br />The overall objective of ore control is to identify and provide the <br />best feed to the mill, with as little dilution or loss pis possible. <br />Consistency is the objective. <br />Any waste material shipped with ore and fed to the mill is referred <br />to as "dilution". Any ore material shipped as waste is referred to <br />as 'loss". Loss of ore is loss of revenue. Dilui:ion of ore <br />reduces daily gold production and increases costs. <br />Rev. 4/20/93 <br />
