REGIONAL AIRBORNE SURVEYS – NOTICE OF ACTIVITY

KEY INFORMATION

  • The airborne gravity surveys will have minimal disturbance to land users and the environment. They will be performed by an experienced specialist contractor and involve a small, fixed wing aircraft flying along flight lines spaced about 200 to 400m
  • The aircraft will fly in public airspace at a nominated ground clearance of 80 to 160 metres, increasing to 300 metres over built-up areas
  • The instruments are passive and do not emit any signals or impact people, animals or infrastructure in any way
  • The survey planes are normal aircraft with scientific instruments on board. Noise levels on the ground will be transient and less than the sound of a passing motorbike
  • The surveys will be conducted over North Central Gold Pty Ltd.’s 35 South Project area from Yaapeet to Warracknabeal in April/May 2022, 34 South Project area from Walpeup to Patchewollock in April/May 2022, Cobar Project Area in July/August 2022

Introduction

North Central Gold Pty Ltd (NCG) was incorporated in January 2020 and was founded to seek and advance new gold and base metal opportunities in Victoria and New South Wales. Despite its proven mineral wealth, the company considers Victoria and New South Wales to be extremely prospective in areas undercover.

NCG manages and operates 35 South Project exploration licences (VIC), 34 South Project exploration licenses (VIC) (see Table 1) and Cobar Project exploration license (NSW) (see Table 2) and is focussed on generating targets using a combination of innovative, non-invasive, low-impact, geophysical techniques.

NCG will be conducting airborne geophysical surveys over its 35 South and 34 South Project exploration licences in April/May 2022.  Cobar Project exploration Licence in July/August 2022. The proposed airborne programs will significantly add to the existing geoscience data and knowledge of the Stawell Corridor and Cobar region and will be made available to the Geological Survey of Victoria and Geological Survey of NSW following quality assurance checks.

The acquisition of high-resolution gravity and magnetic data will enable NCG to “see through” the transported sediments which cover the basement geology of the Stawell Corridor and Cobar region.

Airborne survey method

Aircraft fitted with electromagnetic and gravity instruments map variations in the electrical conductivity and extremely small variations in the natural gravitational pull of rocks, to a depth of several hundred metres without any ground disturbance.

The airborne surveys will be conducted by using a small plane flying around 80-160 metres above ground on an oriented east-west, with a line spacing varying from 200m to 400m apart.

Plane

Timeframes and work area

The surveys will be flown in between April/May 2022 (Victoria) and July/August 2022 (New South Wales).  CGG’s Falcon® Plus will cover the area shown below from Underbool to Warracknabeal and Walpeup to Patchewollock.  From mid-April, Xcalibur Aviation (Australia) Pty Ltd will conduct an airborne survey to help determine electrochemical gradients (the flow of electrons from reducing to oxidising environments or “redox”).

Impact on the environment

The survey planes are normal aircraft with scientific instruments on board, which are passive and do not emit any signals or impact people, animals or infrastructure in any way.  Noise levels on the ground will be transient and less than the sound of a passing motorbike.
