ARRAS MINERALS INITIATES HELI-TEMGEOPHYSICAL SURVEY OF ITS MAISOR AND AKTASTY MINERAL LICENSES, KAZAKHSTAN
Arras Minerals Corp. has commenced its planned 3,381-kilometre airborne (helicopter) electromagnetic (EM) (Heli-TEM) survey has commenced at the company's Bozshakol group of licences. These licences form part of the Teck-Arras strategic exploration alliance announced on Dec. 7, 2023, and are located nearby and surrounding the operating large-scale Bozshakol copper mine, operated by Kaz Minerals.
Highlights from the soil sampling program
- 3,381-line-kilometre Heli-TEM survey over the entire 1,397-square-kilometre Bozshakol project mineral tenement package;
- Survey lines will be flown in a northwest-southeast (125-315) line direction, with lines expected to be approximately 500 metres apart.
Tim Barry, chief executive officer of Arras Minerals, stated: "The commencement of the Heli-TEM survey at the Bozshakol group is an important initiative which we have worked closely with our alliance partners, Teck Resources on planning. The shallow overburden on most of the project has prevented us from completing geological mapping and soil sampling over the properties and this survey will provide a significant amount of quality data to help guide future exploration as we commence our hunt for additional porphyry deposits adjacent to the large-scale Bozshakol copper mine."
Future work will include evaluation of the airborne survey and ground follow-up, including ground-based geophysics surveys, trenching and diamond drilling of identified targets.
Heli-TEM background information
The Heli-TEM system was developed by Fugro Airborne Surveys in the mid-2000s for detection of deep discrete conductive mineral targets or targets obscured by conductive overburden.
The Heli-TEM system is composed of a 40-metre cable that is attached the transmitter loop. The receiver platform and the receiver coil are located at the centre of the 35-metre diameter transmitter loop approximately 0.1 metre above the centre of the transmitter plane. The real-time navigation GPS (Global Positioning System) antenna is on the tail boom of the helicopter. The barometric altimeter, radar altimeter, laser altimeter, video camera and data recorder are all installed in the helicopter. GPS antennae are attached to the transmitter loop to give positional information and transmitter orientation.
The survey uses a 7.5-hertz one-half cycle of the Heli-TEM system that is made up of a square pulse (on time) of approximately 34 milliseconds in duration followed by approximately 34 milliseconds of off time before the pulse is repeated with the opposite polarity. After acquisition, the measured data are windowed into 25 ranges called gates. Gate widths increase as time after turnoff increases because as the energy from the transmitter decays a wider sample must be taken to get a valid average. The position of the first off-time gate is selected after examining several flights of data and is as close to the transmitter turnoff as possible. The power of the pulse causes eddy currents in the system after the turn off and the first off-time gate cannot start until these have died away. The earliest data have had less time to penetrate the subsurface and so contain information from the near surface.
