MINING CONSULTING AND BUSINESS DEVELOPMENT

Mining data
reviewed before the decision.

Southern Mining cross-audits a project's drilling, sampling and mine plan, and delivers technical reports in English and Spanish for owners, producers and investors.

TECHNICAL AND BUSINESS PERSPECTIVE

A sound decision
starts with knowing
where to look closely.

Southern Mining combines project information with mine and plant experience to identify risks, assess alternatives and guide the next step. The work starts by understanding the objective and defining a review appropriate to the project's stage.

WHERE MINING DEALS GO WRONG

Three places where
a decision tends to fail.

Grades with no backing

Laboratory results without blanks, reference materials or duplicates to support them.

Reviewed through: data review and QA/QC
A plan that differs from the real mine

Mine plans that do not match what actually exists in the workings.

Reviewed through: mine plan ↔ actual condition
Reports that do not support each other

Fragmented information, with inconsistencies between drilling, sampling and models.

Reviewed through: cross-source auditing
HOW THE WORK IS DONE

From project information
to a recommendation.

Southern Mining's difference is cross-source auditing: no piece of information is interpreted in isolation. Sources are compared against each other to find inconsistencies before they affect a decision.

01Project information

Reports, drilling and sampling databases, plans and available documentation are received, unfiltered.

02Cross-review

Sources are compared against each other: drilling with sampling, the mine plan with the actual condition of the mine.

03Report and next step

Findings, information gaps, a risk matrix and a prioritised plan, in English and Spanish.

01

Technical project assessment

The available project information is reviewed to establish what is supported, where uncertainty remains and what should be verified before moving forward.

02

Data review and QA/QC

The integrity and consistency of drilling, sampling and laboratory data are examined to identify limitations that may affect their interpretation.

03

Preliminary alternatives assessment

Simplified production, processing and logistics scenarios are compared to identify the variables that matter most to a decision and the information needed for further assessment.

Commercial management and business development

Owners and producers are supported in presenting their projects, connecting with investors and partners, and coordinating commercial discussions grounded in technical information.

TECHNICAL INVESTMENT ASSESSMENT · COPPER, OPEN PIT

Alfa Project

Declared resources, production history, the drilling campaign and the preliminary economics of an open-pit copper deposit were reviewed. The resources were found to be declared but not certified under JORC or NI 43-101, and the drilling QA/QC had not been externally validated.

SMC scorecard: 7.0 / 10, with a risk matrix and a three-phase audit plan.
PRELIMINARY TECHNICAL DIAGNOSIS · Cu-Mo-Re SKARN, UNDERGROUND

Beta Project

Field sampling, a molybdenum flotation test and the historical resources were compared. The review found reversed dates in the sampling database, geotechnical parameters inconsistent with each other, and no blanks, reference materials or duplicates.

SMC scorecard: 5.4 / 10, with information gaps and a prioritised work plan.
MINING PLAN · CONVENTIONAL OPEN PIT

Alfa Project

A plan covering method selection, pit design, phased mine plan, equipment, staffing, operating costs and an economic summary, together with the preconditions that must be met before operating.

Phased plan that starts with a stage of site preparation and data validation.
MINING PLAN · OVERHAND CUT AND FILL

Beta Project

An underground plan with cemented backfill: workings design, operating cycle, equipment, staffing, costs and cash flow, with explicit analysis of geotechnical and grade uncertainty.

First phase designed to validate data before committing capital.

Project names are fictitious. Reports are redacted versions: no location, coordinates, resolutions or client data.

FROM ANALYSIS TO DELIVERABLES

Clear conclusions.
Next steps
with a sound basis.

Each deliverable addresses a specific need: understanding a project's status, reviewing its data, comparing alternatives or preparing a commercial opportunity. Reports and presentations explain findings and guide the actions that follow.

FREQUENTLY ASKED QUESTIONS

What is usually asked
before starting.

What information is needed to begin?

Whatever exists: geological reports, drilling and sampling databases, laboratory certificates, plans and production records. Where information is missing, the report identifies it as a gap.

Is the site visited?

Visits are agreed when they help resolve a specific uncertainty. The review starts from the information provided.

Is the report a resource estimate or a feasibility study?

No. It is a preliminary technical review determined by the quality of the available information, with findings, limitations and recommendations.

In which language are reports delivered?

In Spanish, in English or in both.

How is confidentiality handled?

Each engagement defines what information may be shared and with whom.

A project, its data
and a clear next step.
