Exploration success through advanced geology: programs that answer the geological question within the budget.

ACALA reviews, assesses, designs and implements mineral exploration programs, from target generation and field mapping to geophysics, geochemistry, sampling and QA/QC, so every hole is drilled for a reason. Our geologists know how orebodies form and where they sit across geological and tectonic settings, and they report to SNI, KCMI, JORC 2012, SAMREC and NI 43-101.

Drill hole spacing on a 1,000 by 500 metre target: the number of holes and metres change with the grid spacing 1,000 m 500 m spacing 50 m · 231 holes · 34,650 m at 150 m average depth Typical spacing band: Indicated. The right spacing comes from the variogram, not from habit.
Drill spacing decides the budget and the classification you can claim. Drag the handle from 25 m to 200 m.

Why ACALA for exploration

Geology, geochemistry and geophysics applied to generate targets and to test them.

With blind orebodies increasingly the norm, we routinely use a mineral systems approach to assess prospectivity, and we keep the program within budgetary constraints while it answers the critical geological questions.

Orebody knowledge first

ACALA geologists possess expert knowledge of orebody formation and distribution across geological and tectonic settings. Targets come from that knowledge, not from a grid drawn on a map.

Technology where it pays

Remote sensing, hyperspectral logging, data management and machine learning provide precise and reliable data for exploration decisions.

3D models and clean databases

Proficient in 3D visualisation with GEOVIA Surpac, Geoscience Referential Manager and Geology Modeler, and in exploration databases that keep geological and geochemical data organised, accessible and fully auditable.

Scope of exploration activities

Nine sub-services, combined into one program.

Not limited to the list below. By integrating these sub-services into your exploration program, ACALA helps you reach the project goal efficiently.

  1. 1

    Mineral exploration targeting

    Identifying potential mineral deposits through various techniques and methodologies, including mineral system modelling.

  2. 2

    Remote sensing and geophysics

    Detecting and analysing geological features from a distance, from satellite spectra to ground and airborne surveys.

  3. 3

    Exploration geochemistry

    Studying the chemical properties of rocks, soils and minerals to understand orebody formation and vector towards it.

  4. 4

    Field structural analysis

    Examining geological structures in the field to determine their control on mineral deposits.

  5. 5

    Mineral exploration project planning

    Detailed plans for exploration projects, including timelines, budgets and resource allocation.

  6. 6

    Sampling, analysis and QA/QC

    Collecting and analysing samples, with standards, blanks and duplicates, so the data is of a quality a resource estimate can rest on.

  7. 7

    Exploration field services

    On-site support and expertise for exploration activities, including supervision of drilling and logging.

  8. 8

    Exploration operation health and safety

    Ensuring all exploration activities are conducted safely and in compliance with regulations.

  9. 9

    Exploration project audit and valuation

    Assessing the value and potential of exploration projects through thorough audits and evaluations, plus strategy and governmental advice.

Reports that travel

Internal reviews and independent technical reports that exchanges, banks and investors rely on.

ACALA specialists adhere to SNI, KCMI, JORC 2012, SAMREC and NI 43-101 best practice and reporting requirements. Our reports provide insights and recommendations that help stakeholders make informed decisions about their exploration projects.

Questions we get

Exploration FAQ

Can ACALA review a program we have already designed?
Yes. Reviewing and assessing existing programs is part of the service: targets, drill spacing, sampling protocol, QA/QC and budget are checked against the geological question the program is meant to answer.
What is a mineral systems approach?
Assessing prospectivity by the whole system that forms a deposit, such as source, pathway, trap and preservation, rather than by surface showings alone. It is the approach that finds blind orebodies.
Do you supervise drilling on site?
Yes. Exploration field services include on-site supervision of drilling, logging, sampling and health and safety, with data entering an auditable database as it is collected.
Which software do you deliver the data in?
GEOVIA Surpac databases and models, and the Geoscience Referential Manager and Geology Modeler roles on 3DEXPERIENCE, so your team can keep working on the same files.
Can the result be reported publicly?
Yes. Exploration results and the resource estimates that follow are prepared to SNI, KCMI, JORC 2012, SAMREC and NI 43-101, with Competent Person sign-off where required.
