1. Data Collection Drilling
-
1.1 Flowsheets of procedure manuals exist, match current procedure and are presented.<br>
-
1.2 Rationale and Objectives of resources development drilling is clear and is discussed.
-
1.3 Survey Methods (both collar and downhole) and quality control checks.
-
1.4 Survey procedures ensure timeline of collar and downhole pick ups and that there are no backlogs for resource estimation.
-
1.5 Drilling type (Diamond, RC, Etc) and suitable to mineralisation and estimation purposes.
-
1.6 Documentation of drilling details since last resource estimate (core diamond, hole size, hole depth etc.)
-
1.7 Measure to maximise recovery, evidence of records of RC and DDH recovery.
2. Data Collection - Sampling
-
2.1 Flowsheets or procedure manuals exist, match current procedures, and are presented
-
2.2 Sample collection procedures are consistent and repeatable
-
2.3 Sample interval(s) related to mineralisation style(s) and geology, and are appropriate for resource estimation purposes
-
2.4 Sample number assignment procedures logical and clear; exceptions (i.e.. redrills, lost sample) accounted for
-
2.5 Sample spacing and orientation suitable for minerilsation boundaries and for resource esrtimate
-
2.6 Nature and types of sample (half core, riffle split, wet, etc)
-
2.7 Sample mass appropriate for particle size, mineral and grade of mineralisation
-
2.8 Sample recovery recorded and assessed with respect to resource estimate
-
2.9 RC drilling cyclone dust reject sampling undertaken
