Geological Mapping
The foundation of exploration: recording rock types, structures and alteration patterns that indicate mineralizing systems.
Mineral Exploration
Mineral exploration: turning geological ideas into resources
Exploration is where every mine begins — and where most prospects end. It is a staged, evidence-driven process designed to find deposits while spending wisely and disturbing as little ground as possible.
Why Exploration Matters
Discovery is rare — and earned
Only a small fraction of mineral prospects ever become mines. Exploration is therefore a process of progressively reducing uncertainty: each stage tests a geological idea, and only the most promising targets advance to the next, more expensive step.
Good exploration combines geological insight with modern technology and careful field practice. It also begins the relationship with landholders and communities — a relationship that should be built on transparency from the very first visit.
Exploration Planning
A staged approach to discovery
Each phase is designed to answer specific questions before larger budgets are committed.
Stage 1
Desktop study & targeting
Review of geological maps, historical data, satellite imagery and regional geophysics to identify prospective areas.
Stage 2
Field mapping & reconnaissance
Geologists map rock types, structures and alteration, and collect rock-chip samples to confirm mineralization.
Stage 3
Geochemistry & geophysics
Soil, stream-sediment and rock sampling, combined with ground or airborne surveys, define drill targets.
Stage 4
Drilling
Reverse-circulation and diamond-core drilling test targets at depth and provide samples for assay.
Stage 5
Resource definition
Infill drilling, modeling and estimation define the size, grade and confidence of the deposit.
Geological Surveys
Modern exploration methods
Geochemical Sampling
Soil grids, stream sediments and rock samples reveal subtle chemical halos around buried deposits.
Airborne Geophysics
Magnetic and radiometric surveys from aircraft or drones map geology beneath soil and vegetation cover.
Induced Polarization & EM
Electrical methods detect disseminated sulfides and conductive bodies often associated with gold and silver.
Remote Sensing
Multispectral and hyperspectral imagery identify alteration minerals across large areas.
3D Integration
All datasets are combined in 3D geological models to rank targets and design drill programs.
Mineral Sampling
Drilling and sample integrity
Drilling is the only way to confirm what lies beneath the surface. Reverse-circulation (RC) drilling produces rock chips quickly and cost-effectively, while diamond-core drilling recovers intact cylinders of rock that reveal structure, texture and mineralogy.
Every sample must be traceable and representative. Chain-of-custody procedures, accurate downhole surveys and a quality assurance program using blanks, duplicates and certified reference materials ensure that assay results can be trusted.
- Core logging of lithology, alteration, structure and mineralization
- Independent, accredited laboratory analysis
- QA/QC monitoring on every batch of assays
Resource Assessment
From results to a reported resource
| Category | Level of confidence | Typical data density |
|---|---|---|
| Inferred | Lowest — geological continuity is assumed rather than verified | Wide-spaced drilling |
| Indicated | Moderate — continuity reasonably assumed for planning | Closer-spaced drilling with QA/QC |
| Measured | Highest — continuity confirmed in detail | Close-spaced drilling and sampling |
Public reporting of resources and reserves follows recognized codes such as JORC, NI 43-101 or SEC S-K 1300, and must be prepared or supervised by a qualified or competent person.
Low-Impact Exploration
Exploring responsibly
Exploration can be carried out with a light footprint. Drill pads and access tracks are kept to a minimum, sumps are lined and backfilled, and disturbed areas are rehabilitated promptly after each program.
Before ground disturbance, cultural heritage surveys and landholder consultation help ensure that sensitive sites are protected and that local people understand what is planned.
