Drill Hole Planning

Each hole should be designed to test specific geological features. Hole Design Collar Location - Access considerations - Environmental constraints - Previous drilling Orientation - Azimuth: perpendicular to target strike - Dip: intersect target at optimal angle - Rule of thumb: 30° to target orientation Depth - Deep enough to test target - Budget constraints - Technical limits Hole Naming Convention - Systematic naming - Include property/project code - Sequential numbering - Examples: ABC-DDH-001, PROJECT-RC-156
