Turning complex geological data into decisions you can defend.
Silver Compass LLC is a Houston-based consultancy in applied geology, GIS, remote sensing, technical due diligence and project development for mining, geothermal energy, critical minerals and natural resources.
Based in the USA, with a deep technical and commercial network across Argentina and Latin America.
Geology, GIS, remote sensing, target generation, due diligence, exploration strategy and investor-facing materials.
Geological judgment plus business perspective plus the ability to explain both to a board.
Who we are
A bridge between geological information and investment decisions.
Silver Compass LLC supports decisions in natural resource projects where technical quality, territorial insight and commercial opportunity have to line up.
Our work is translation. We take maps, satellite imagery, historical records, geochemistry, geophysics, permitting, infrastructure and economic context, and turn them into concrete criteria: advance, focus, verify, renegotiate or walk away.
The approach is deliberately pragmatic. We prioritise what adds value, identify risk early, and design phased programmes that test the hypothesis without inflating budgets or building expectations the data cannot support.
Producing maps and reports is not the objective. The objective is a clear, prioritised and defensible roadmap.
Field + data integration
Geology, remote sensing and spatial data are strongest when they are interpreted together.
What we do
Expert geological consultancy
Geoscience, practical training and spatial intelligence for mining, geothermal and oil & gas projects.
Earth sciences consulting
Geological evaluation, exploration planning and technical due diligence. We integrate field evidence, geochemistry and geophysics to prioritize targets, assess risks and define the next stage.
Mineral exploration · Geothermal assessment · Energy resources
GIS training
Tailored training for mining and oil & gas professionals. We help teams organize geological data, build useful maps and apply GIS workflows to real exploration and operational decisions.
Applied learning · Geological data · Team capability
Geospatial solution development
Integrated GIS databases, mapping and remote sensing that turn dispersed information into a coherent geological interpretation. From alteration mapping to regional targeting and decision-ready spatial products.
GIS & mapping · Satellite interpretation · Target generation
Selected work
Innovative resource solutions
Selected experience connecting technical knowledge with practical results in exploration, evaluation and resource supply.
GIS training for industry professionals
Applied GIS training programs for mining and oil & gas teams, focused on geological information management, spatial analysis and everyday project workflows.
Geospatial solutions for exploration
Work in Argentina, Colombia and Chile combining GIS, satellite interpretation and geological data. Regional programs integrate lithostructural analysis, alteration mapping and target prioritization for base, precious and critical minerals.
Geological evaluation & due diligence
Assessment of strategic mining assets, including work in Portugal and Idaho. We review geological evidence, data quality and exploration risk, and translate findings into validation plans, investor materials and development decisions.
Wet sand & proppant supply chains
Identification and evaluation of sand sources, logistics analysis and near-well supply models. The focus is on reducing transport, handling and total completion costs while assessing operational and environmental trade-offs.
Further experience: geothermal prospect evaluation, uranium and critical-mineral opportunities, historic district reactivation and phased exploration programs.
What we are — and what we are not
Credibility starts with knowing the limits of the data.
Silver Compass does not replace an exhaustive exploration campaign or a full technical audit where one is required. Our strength is designing the right path to that decision with less noise, less improvisation and better technical support.
We flag assumptions. We separate what is verified from what is inferred. And we say when the data does not support the conclusion someone wants.
Where our experience sits
Mining, critical minerals, geothermal and industrial materials.
How we work
Five phases, each one answering a specific question.
Uncertainty is reduced progressively. Each phase must produce an operational decision: advance, focus, verify, renegotiate or drop.
Review & Screening
Compile available information, detect critical gaps, review historical records and define exploration hypotheses.
GIS & Remote Sensing Integration
Build the geospatial base, process satellite data, identify patterns, alteration, lineaments and priority areas.
Target Prioritisation
Rank areas by potential, risk, accessibility, quality of evidence and cost-benefit.
Field Validation
Design focused mapping and sampling campaigns, anomaly checking, infrastructure verification and risk assessment.
Due Diligence & Roadmap
Issue a technical opinion, define next phases, preliminary budgets, risks, opportunities and executive material for decision-making.
A phased structure protects the budget. It also protects the argument: every recommendation can be traced back to the evidence that produced it.
International Market Development
From Argentina to new international markets.
Silver Compass supports the commercialization and international positioning of selected Argentine products, connecting suppliers with potential buyers, partners and decision-makers abroad.
Our focus includes Europe and the Middle East, combining commercial outreach, technical understanding and strategic positioning to help products enter new markets.

Representation & Commercialization
Middle East · Europe · North America
Silver Compass LLC represents MAREF and supports the commercialization of TS PLUS in the Middle East, Europe and North America. We connect operators, drilling contractors and commercial partners with product information and the MAREF team.
MAREF GROUP · DRILLING SOLUTIONS
TS PLUS
Preventive sealing for demanding drilling conditions.
TS PLUS is a vegetable-fiber blend described by MAREF as a low-invasion sealing agent. It is designed to help limit fluid invasion, support wellbore stability and prevent circulation losses in permeable or depleted formations.
Preventive application
Introduced before entering the target interval, with treatment selected for the formation and drilling program.
Fluid-system integration
MAREF describes applications in water-based and non-aqueous drilling fluids. Suitability and dosage require technical review.
Field experience
MAREF’s performance report documents applications in Vaca Muerta, Argentina. Results depend on well conditions and the treatment program.
