• - [f the core hole is a twin to a rotary hole any significant variation in <br />alteration and lithology should be noted in your weekly report and <br />brought to the a[tention of the project geologist. <br />SAMPLING OF CORE HOLES <br />- Samples should be selected using geologic and mineralization criteria. <br />In the absence of geologic variations use five foot sample intervals. <br />- Always split or saw core perpendicular to the structure or veining. <br />- Be aware of the ore types for the project area and try to make sample <br />breaks at these boundaries when possible. <br />- Always sample vein and sheeted zones separately and have intervals <br />sawed. Areas of expected or obvious high grades (>.LQQ opt) should <br />be sawed, other area can be split using the hydraulic splitter. <br />ORE TYPE AND METALLURGICAL DATA <br />• - Be familiar with ore types of the project and focus on the features <br />which distinguish them apart. <br />Periodically check pyrite content in core by splitting a section and look <br />at a broken surface. <br />BASIC FLOW SHEET FOR CORE LOGGING <br />Lay out core (beginning at top of hole) <br />Log Geotech data <br />- L.og geologic data <br />- Flag sample breaks <br />- Review log and core to make sure data is present for ore type <br />definition <br />- Remove skeleton samples and glue on library board <br />• - Photograph core (use sprayer to wet down core before photo) <br />
