Running tool/data capture device (20, 220) is deployed downhole (102) with a drill assembly. Core sample is drilled (104) and drilling ceases (106). Core is broken and a physical factor (second factor) associated with core break is measured/sensed/detected/recorded (108) – signature of core break occurring. The signature (second data) is associated to the orientations during ceased drilling before core break (110). Orientation recordings/first data not commenced by sensing or detecting core break. Orientation recordings occur regardless of drilling or not drilling. Relate signature of core break activity to the first data to identify target data orientation recordings having the correct orientation when the core drill and sample were steady. Tool can receive signal downhole initiated at the surface, the signal associated with at least one function of the data capture device and/or with orientation data recorded by the data capture device.

A method and system for obtaining orientation of a core sample core drilled from underlying rock. A core orientation recording device (116) records its orientation at random and/or non-predetermined time intervals from a reference time during a drilling operation. The time intervals are generated to be within a range of minimum and maximum time intervals. After a time interval elapsed from the reference time plus a wait time of at least the minimum random or non-predetermined time interval, the core sample is separated from the underlying rock and brought to the surface and its original orientation is determined from orientation data recorded closest in time to the elapsed time plus the minimum time interval. A remote communicator (160) having the elapsed time interrogates the core orientation recordal device (116) to identify the required orientation data and requires the core orientation recordal device to identify a correct orientation of the core sample.

A method and system for obtaining orientation of a core sample core drilled from underlying rock. A core orientation recording device (116) records its orientation at random and/or non-predetermined time intervals from a reference time during a drilling operation. The time intervals are generated to be within a range of minimum and maximum time intervals. After a time interval elapsed from the reference time plus a wait time of at least the minimum random or non- predetermined time interval, the core sample is separated from the underlying rock and brought to the surface and its original orientation is determined from orientation data recorded closest in time to the elapsed time plus the minimum time interval. A remote communicator (160) having the elapsed time interrogates the core orientation recordal device (116) to identify the required orientation data and requires the core orientation recordal device to identify a correct orientation of the core sample.

Orientation data representing a required orientation of a core sample held in a core tube (22, 50) prior to separation of the core sample (24, 52) from the underlying rock can be recorded by a data gathering device (42, 80) at least while drilling is ceased and closest to time Tx, where Tx can be greater than, less than or equal to T-t, where T is the time recorded by the data gathering device (42, 80) and t is the recorded elapsed time commenced and recorded by a communication device (60) at the surface. Elapsed time t commences at the surface when drilling ceases and preferably before the core is to be broken from the underlying rock. For regular time intervals I between orientation data measurements, there can be a time delay W from commencing the elapsed time t. This time delay should be at least as long as (I) a time interval between taking orientation measurements plus the time to actually measure an orientation. After the delay W has elapsed, the core can be broken from the underlying rock. The data gathering device (42, 80) is interrogated at the surface by the communication device (60), and at the same time both timers are stopped or their individual times associated with each other (survey time T and elapsed time t). Target recorded orientation data Tx can be identified as the largest Tx value < T-(t-W) i.e. the oldest Tx in time from commencement of T after taking the mark and before or by the end of the delay W time. Alternatively, for elapsed time t commenced at the end of the delay period W from taking the mark, the recorded orientation data can be identified as the smallest Tx value > T-(t+W) or the largest Tx value < T-t.

Apparatus (100) for measuring drilling parameters of a down-the-hole drilling operation for mineral exploration includes a module 10.1 mounted in-line with a drill string (110) and proximate to a drill bit (120). The drill string (110) is rotated and progressed down the hole. The module (10) has sensors for sensing conditions. The apparatus (100) measures drilling parameters based on the sensed conditions. The measured data is logged in the module (10) and then transmitted to a computer for a drilling operator's use. The drilling operator monitors progress and optimises performance of the drilling operation based on the measured data. Measurement of drilling parameters based on sensed data proximate to the drill bit enables accurate determination of actual WOB, torque and RPM fluctuations, axial vibration, radial vibration, temperature, RPM. A second module 10.2 is mounted in-line with the same drill string (110) but away from the drill bit (120). The second module 10.2 measures the same drilling parameters as the module 10.1 proximate to the drill bit (120). The driller is provided with the data recorded by the second module 10.2 to judge the performance of the drilling operation. Comparing drilling parameters based on sensed data proximate to the drill bit and distal to the drill bit enables accurate determination of vertical drag/resistance of the drill string (110) within the hole, rotational resistance of the drill string (110), degree of wind-up of the drill string (110) and presence of stick-slip conditions at lower end of the drill string (110).
