The Managing Director and owner of Durock Drilling, Brock Dunlop, has over ten years experience providing drilling services throughout Australia.  Brock started Durock Drilling when he relocated from Kalgoorlie WA to his home town of Dubbo NSW in 2018, to concentrate on customers based on the East Coast of Australia. 

Durock Drilling prides itself on being a quality and safety focused exploration contractor and to this end Brock has gained a reputation within the drilling industry for providing quality drilling programs with the ability to establish excellent client and contractor relationships.  

The goal of the entire team at Durock Drilling is to work hard to develop long term relationships with companies exploring and mining on the East Coast of Australia.  We strive to deliver cost effective and safe outcomes and take great pride when  we receive feedback from our client's that we have not only met, but exceeded, their expectations.

Having many years of drilling experience among our team members, we offer safety focused, technically competent and cost effective exploration drilling services.  Our staff are recruited based on their qualifications and competency in their area of expertise. 



All Employees, Contractors, Subcontractors and Visitors are required to comply with the provisions of the WHSMS whilst working on Durock Drilling sites or equipment. The Standards, Procedures and Tools within the system are used to assess the performance of each employee and contractor and provide the basis for determining the development, acceptance and implementation of tasks and process specific to Work Health and Safety Management Plans.

Employees across all levels of the organisation, along with contractors, have the authority to provide input into the effectiveness of the WHSMS and have a responsibility and accountability to ensure implementation, execution, monitoring and improvement of the system. 

To ensure we have a common approach to managing business performance and achieve ongoing improvement across Durock Drilling, we focus on the systematic identification, management and improvement of the areas of our business that can present risk.

This approach applies to the management of our activities across the business in the areas of:

  1. Personal Safety,
  2. Heavy Vehicle operations in line with Heavy Vehicle National Law,
  3. Asset Management & Operational Integrity – to further improve on the reliability and integrity of our plant and equipment and support the ongoing improvement to our health and safety performance.

This enables Durock Drilling to apply best business practice so we can:

  • Centrally identify, evaluate and manage risk across the business or site – as often risks are inter-related;
  • Centrally manage requirements for standards and certification;
  • Rationalise resources;
  • Reduce complexity;
  • Improve performance;
  • Improve customer satisfaction;
  • Maintain and enhance reputation; 


RC Drilling

Reverse Circulation drilling, or RC drilling, is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow. Reverse Circulation drilling produces small rock chips through a large rotary drill and air compressor. Durock Drilling’s rotary splitting and inline systems produce dry and excellent quality samples.

Diamond Drilling

Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the ore body,  geologists can analyse the core by chemical assay and conduct petrologic, structural and mineralogical studies of the rock.  Diamond core drilling is the most informative and effective method of drilling used in exploration. Durock Drilling provide fully orientated, high quality core samples through HQ/HQ3, NQ2 and PQ3 sized drill bits

Air Core Drilling

Air core drilling can occasionally produce small chunks of cored rock. This method of drilling is used to drill the weathered regolith, as the drill rig and steel or tungsten blades cannot penetrate fresh rock.  Air core drilling can achieve depths approaching 300 metres in good conditions.
