AusQuest Limited (ASX:AQD) has initiated an Induced Polarisation (IP) and magnetotelluric (MT) survey at its Coober Pedy iron-oxide copper-gold (IOCG) Project in South Australia. The company announced the commencement of this geophysical survey, executed by GRS Pty Ltd, aiming to map potential sulphide mineralisation across approximately 50 kilometers using pole-dipole IP and MT readings.
Strategic Location within the Olympic Dam Province
Located at the northern end of the Olympic Dam IOCG province, near the Gawler Craton, the Coober Pedy project holds significant geological promise. This region is renowned for its rich mineral deposits, including the nearby Olympic Dam and Prominent Hill mines, both of which have historically yielded substantial copper and gold outputs. AusQuest’s focus on this area underscores its strategic intent to leverage the geological similarities and maximize the project’s potential.
The current survey at Coober Pedy is designed to further delineate the mineralised zones identified through previous regional magnetic and gravity data analyses. The survey’s outcome is anticipated to refine drill targets, providing a clearer path for subsequent exploration phases. This effort is part of a broader strategy to harness detailed geophysical data to mitigate exploration risks and enhance the accuracy of drilling interventions.
Historical Context and Recent Developments
AusQuest’s exploration endeavors at Coober Pedy have seen a series of developments over the past few years. In 2025, the company conducted a maiden reverse circulation (RC) drilling program, which comprised eight drill holes totaling approximately 3,000 meters. The results were promising, with seven out of eight holes encountering broad copper mineralisation, leading the company to describe the findings as indicative of a new, large-scale porphyry copper discovery.
However, drilling operations were paused in mid-2026 after encountering technical challenges. Specifically, an unconsolidated sand unit obstructed the drilling rig, halting progress after only three of the planned fifteen holes were completed. AusQuest has since planned to employ a second contractor with a mud rotary drilling rig to overcome these geological hurdles and resume drilling activities to target depths of around 350 meters.
Implications for AusQuest and the Broader Mining Sector
The resumption of exploration activities at Coober Pedy is a critical milestone for AusQuest as it seeks to unlock the full potential of this project. The successful identification and delineation of mineralised zones could position the company as a significant player in the IOCG space, competing with established operations in the Olympic Dam province. Moreover, the data gleaned from the IP and MT survey will be pivotal in guiding future drilling campaigns, potentially accelerating the project’s development timeline.
This development also reflects a broader trend within the mining sector, where companies are increasingly deploying advanced geophysical techniques to enhance exploration efficiency. By integrating cutting-edge survey technologies, AusQuest aims to optimize its exploration outcomes, reduce costs, and increase the probability of discovery, which could have far-reaching implications for its strategic partnerships and investment profile.
The Coober Pedy project, potentially under a strategic joint venture with South32, is a testament to the ongoing interest and investment in the IOCG province, known for its world-class mineral deposits. As the exploration progresses, stakeholders will be keenly observing the assay results from the completed holes, expected soon, which could provide further insights into the project’s viability.
As AusQuest continues its exploration activities, the next few months will be crucial in determining the project’s trajectory. The company’s ability to effectively leverage geophysical data and adapt its drilling strategy in response to encountered challenges will likely define its success in the competitive landscape of IOCG exploration.
