Reviews at different scales.
Start with the 48-hour independent target review.

Standalone rapid review

01

48-Hour Independent Target Review

A rapid assessment of an individual project or prospect using available geological, geochemical, geophysical and drilling information.

Focus: Target quality, geological controls, overlooked opportunities, data gaps and prioritisation.

Typical deliverables: Concise technical summary, annotated figures/maps, ranked targets and a discussion with the exploration team.

02

Exploration Target and Portfolio Assessment

A broader review across multiple projects or tenements to determine where exploration expenditure is most likely to create value.

Focus: Comparative prospectivity, project ranking, exploration maturity, technical risk and allocation of exploration capital.

Typical deliverables: Project ranking matrix, key value drivers, principal technical risks and recommended priorities.

03

Target Generation & Re-Targeting Review

A deeper review aimed specifically at identifying new targets or reassessing areas that may have been discounted by previous exploration models.

Focus: Structural controls, mineral-system architecture, alternative geological interpretations, untested target positions and integration of legacy datasets.

Typical deliverables: New target concepts, ranked target areas, supporting rationale and recommendations for follow-up work.

04

Pre-Drill Target Validation

An independent technical check before committing to drilling.

Focus: Whether the proposed drill target is supported by the available datasets, whether the geometry is appropriate, and whether alternative drill positions may provide greater value.

Typical deliverables: Target validation, drill-priority recommendations, key uncertainties and suggested modifications where appropriate.

05

Technical Due Diligence / Acquisition Review

Independent review of an exploration project being considered for acquisition, joint venture, farm-in or investment.

Focus: Geological upside, quality of existing targets, data reliability, exploration maturity, technical risks and potential hidden value.

Typical deliverables: Concise technical opinion, key strengths and weaknesses, principal risks, value-creation opportunities and priority questions for management.

06

Structural & Mineral-System Review

A specialist review focused on the geological architecture controlling mineralisation.

Focus: Structural framework, fluid and magma pathways, timing relationships, deformation history, mineralisation controls and implications for targeting.

Typical deliverables: Revised geological/structural interpretation, target implications and recommended next-stage work.

07

Exploration Strategy Review

A higher-level review of whether the current exploration program is asking the right geological questions.

Focus: Exploration philosophy, targeting logic, sequencing of work programs, technical assumptions and whether expenditure is aligned with the highest-value opportunities.

Typical deliverables: Strategic recommendations, exploration priorities, decision points and suggestions for improving the effectiveness of future exploration expenditure.

08

Investor / Board Technical Review

An independent technical assessment prepared for management, boards or investors who require a concise view of a project's exploration potential.

Focus: Technical credibility, key value drivers, major uncertainties, exploration upside and the significance of upcoming work programs.

Typical deliverables: Executive-level technical summary, key risks and opportunities, and presentation-ready material if required.

The objective across all review options is not to replace the existing technical team, but to provide an independent senior-level second opinion aimed at identifying untapped exploration value, challenging established assumptions and improving the effectiveness of the next exploration dollar spent.
