Technical and strategic consulting for the evaluation, promotion and development of mining, geothermal and natural resource projects.
Houston · Argentina · Latin America · International markets
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 Houston, Texas, 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
Integrated service lines.
Delivered individually or as part of a complete phased programme, depending on the decision that needs to be made.
Mineral Exploration & Target Generation
Integration of geology, geochemistry, geophysics, remote sensing and historical information to rank areas of interest and define defensible exploration targets.
GIS, Cartography & Geospatial Databases
GIS bases, regional and detailed mapping, shapefiles, geodatabases, GeoTIFF and decision-ready spatial products structured for reuse.
Remote Sensing & Hyperspectral Analysis
ASTER, Sentinel, WorldView and VNIR–SWIR–TIR interpretation for alteration mapping and exploration vectoring within a geological framework.
Technical Due Diligence
Independent review of geological information, asset status, technical risk, information gaps and unverified assumptions, with an explicit recommended course of action.
Geothermal & Energy
Preliminary geothermal assessment, conceptual-model review, staged validation and technical-commercial support, including applications linked to mining and industrial heat.
Frac Sand & Wet Sands
Resource evaluation, logistics, proximity to operations, cost-reduction analysis and opportunity assessment for unconventional oil and gas development.
Investor-Facing Materials
Project profiles, executive presentations, technical summaries, commercial narratives and promotion strategies built on evidence, with risks and gaps stated clearly.
International Commercialization
Commercial representation and market-entry support for selected Argentine products, connecting suppliers with potential buyers and strategic partners in Europe and Arab markets.
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.
Selected work
A generic track record. No confidential names required.
The examples below describe the type and scale of work developed by Silver Compass and its technical leadership without disclosing client, property or project names.
Critical Minerals & Uranium
Technical and strategic review of uranium and critical-mineral opportunities, including geological potential, information quality, development options and value-chain analysis.
Regional Exploration & Target Generation
Cu-Au-Ag, Li and REE programmes integrating historical data audit, GIS, lithostructural interpretation, target ranking and field-validation design.
Regional Remote Sensing
Integrated hyperspectral and multispectral programmes at regional scale, combining spectral processing with validated geology to convert anomalies into defensible targets.
Geothermal
Evaluation of geothermal prospects and portfolios, including geophysics, geochemistry, thermal manifestations, remote sensing and staged validation plans.
Due Diligence & Asset Review
Independent review of mining and critical-mineral assets in the Americas and Europe, integrating field data, GIS and technical analysis for acquisition and development decisions.
Reactivation, Investor Materials & Energy Support
Reactivation planning for historic mining districts, investor summaries, executive presentations, frac-sand exploration support and GIS consulting for energy-sector clients.
Experience across
Argentina · Chile · Colombia · Paraguay · United States · Portugal · Suriname
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 Arab markets, combining commercial outreach, technical understanding and strategic positioning to help products enter new markets.

Why Silver Compass
Five reasons clients bring us in.
Technical judgment with a commercial lens
Geology is used as a tool for deciding investments, prioritising resources and building opportunities.
Multi-source integration
Geology, remote sensing, GIS, geochemistry, geophysics, history, infrastructure and operating constraints in one coherent reading.
Executive communication
Reports, presentations and technical narratives that boards, investors, public agencies and strategic partners can use.
Regional and international perspective
A Houston base with technical and commercial reach across Argentina, Latin America and international markets.
Phased approach
Scalable programmes that validate hypotheses and manage budget without loosening technical rigour.
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.
Technical leadership
Marisa N. Franciosi
Director · Senior Geologist · GIS Geoscientist · MBA
Silver Compass is led by Marisa N. Franciosi, an Argentine senior geologist based in Houston with more than 25 years of international experience in mineral exploration, geothermal energy, GIS, remote sensing, project evaluation and strategic opportunity development.
Her career combines field geology on major projects with advanced geoscientific and spatial-data workflows. She leads regional analysis, historical database audits and exploration target generation for copper, gold, silver, uranium and critical-mineral projects.
The dual technical and business profile helps align exploration programmes with commercial viability and the due diligence standards required by investors and public-sector entities.
Working with partners
Specialist capacity, scalable by project.
Silver Compass works with specialised technical partners in Argentina and Latin America, allowing field teams, local capability and regional presence to scale without losing technical control of the deliverable.
