On-site consulting Our core business is on-site consulting anywhere in the world with emphasis on structural, fluid, or terrane complexity.

We have between us over 70 years of experience in a broad spectrum of terranes and commodities, although we individually offer different levels of specialisation in different aspects (see About Us). Projects can be arranged through any one of the HCO Principals. Projects can be serviced, at the client's discretion, by any of the HCO Principals, alone or in any combination.

Project details are kept confidential to the HCO person(s) actively servicing the project. Each Principal operates as an independent business and contracts and invoices are between the client and the active Principal.

3-D modeling HCO integrates on-site structural mapping and analysis of complex targets with the design and production of 3-D structural models, fully interpreted and linked to the exploration program.

Modeling programs can be on a continuing development basis as part of our one-on-one consultancy service, or as a turnkey package with one or more HCO Principals involved, and other Associates as required.
Turnkey package quotes are a two stage process:
1. - a short on-site program (7-14 days) to assess the scope of the problem and provide initial analysis of the structure and its relationship to mineralisation. This short study may be all that is needed to enhance understanding of the project and guide future exploration without further committment.
2. - submission of a turnkey quote for a full 3-D model. The cost and time required (up to 6 weeks) depends on the nature of the problem, the precision of the required model, the volume of available data, and the amount of new data or mapping that needs to be collected.

Target generation and terrane prioritisation HCO apply detailed time-space analyses, tectonic and metallogenic studies to prioritise geologic terranes. Priority geologic terrane forms the focus for confident opportunity identification and for the generation of new projects and exploration targets.

QA/QC of exploration practices HCO can provide QA/QC evaluation and advice in the following:
� Oriented drill core practices and structural data evaluation (Rod Holcombe)
� Assay and geochemical database evaluation (Nick Oliver)
� Exploration strategies and risk analysis in frontier environments (Tim Coughlin)

On-site training We provide on-site training at any level in structural geology, metamorphic geology, fluid and alteration geochemistry, tectonics, and terrane evaluation. In doing so we draw on over 50 years of teaching experience between us.

Three levels of training are provided:
� Entry-level courses in mine and pit structural mapping, alteration mapping, and basic structural geology
� Intermediate level courses in structural geology, field mapping and structure, and hydrothermal geochemistry
� Advanced courses in structural analysis, shear zone analysis, hydrothermal systems analysis

Hydrothermal systems/fluid pathways analysis Nick Oliver brings over 30 years of experience in 'hydrothermal' geology in structurally complex terranes to provide practical field-based analyses of hydrothermal framework of mineralisation at both the deposit-scale and regional exploration scale. Deliverables include:
� An analysis of the core elements of the alteration, geochemistry, geometry, and timing of fluid flow pathways that have led to mineralization
� Maps, sections and reports identifying fluid pathways and rock interactions and suggesting alternatives for testing;
� Practical �toolkits� of sampling and logging procedures tailored for each deposit;

Analyses would normally be in two stages starting with a shart scoping program (7-14 days) to assess the scale of the problem, provide initial analysis, and define the scale of any further work that would be required to provide complete solutions. See here for more details...
