High-Yield Geological Data Through Flawless Execution.

In exploration, a borehole is more than an opening in the ground - it is a critical data asset.

Lucas combines a modern, multi-purpose drilling fleet with elite, professional crews to deliver the precise structural and stratigraphic data needed to de-risk investments and define resource models.

Operating extensively across Australia's most complex basins, we have built a reputation for achieving exceptional core recovery and pristine sample quality under challenging geological constraints, ensuring your exploration investment translates directly into trusted asset valuation.

Minimising Resource Uncertainty, Maximising Core Recovery

The value of an exploration programme relies entirely on the integrity of the data recovered. Lucas eliminates the operational disconnects that lead to lost core, contaminated samples, and compromised data arrays.

  • Elite Sample Integrity
    Whether deploying diamond coring or rotary mud systems, our crews treat every metre drilled as a high-value geological sample. We focus aggressively on maximizing core recovery percentages, even when passing through highly fractured, friable, or unconsolidated strata.
  • Fit-for-Purpose Fleet Deployment
    Our modern, rigorously maintained fleet features versatile, multi-purpose rigs capable of switching seamlessly between diverse drilling methodologies without costly mobilisation delays.
  • Geologist-Centric Field Operations
    Our supervisors understand the ultimate objectives of the exploration campaign. By maintaining constant communication with site geologists and technical directors, we ensure that changing downhole conditions are immediately met with the correct operational adjustments.

The Integrated Advantage:
Drilling for Geological Truth

Aligning the field execution directly with the data needs of resource geologists.

What drilling methods do we utilise?

We possess the specialised technical capability to execute a wide array of exploration activities across varied ground conditions:

  • Diamond Core & Conventional Coring
    Delivering high-integrity, uncompromised core samples for precise geotechnical evaluation and stratigraphic correlation.
  • Down-Hole Hammer (DHH) & Air Drilling
    Providing rapid penetration rates through hard-rock strata to accelerate resource boundary mapping.
  • Rotary Mud Drilling
    Utilising highly calibrated mud programmes to ensure wellbore stability and precise chip sampling when navigating deep, unstable, or high-pressure overburdens.
  • Deep Hole Exploration
    Safely managing torque, drag, and hole cleaning metrics to extend exploration depth parameters well beyond standard drilling limits.

Securing the Asset and the Environment

Exploration often means operating in remote or environmentally sensitive areas. Through our Safety in Design (SiD) framework, Lucas systematically plans out operational and environmental risks long before a rig moves to the pad.

  • Advanced Well Control Planning
    Pre-modelling pressure profiles and designing strict casing and fluid parameters to eliminate the risk of lost circulation or well-control incidents.
  • Footprint Minimisation
    Engineering tight, highly efficient site footprints and fluid containment systems to radically reduce environmental impact and streamline the rehabilitation process.
  • Rigorous Risk Harmonisation
    Conducting comprehensive pre-spud hazard reviews to reduce residual risk to As Low As Reasonably Practicable (ALARP), meeting the absolute compliance requirements of Tier 1 resource companies.

Define Your Resource with Absolute Certainty.

Don't compromise the integrity of your geological data with substandard core recovery or operational delays. Partner with Lucas to ensure your exploration campaign is delivered safely, precisely, and on schedule.
