Mining Corporations

Mining is one of the few industries where water management combines massive use (dewatering, processing, tailings), persistent contamination (ARD/AMD, metals, cyanide, sulfates), and multi-generational legacy liability (closure, perpetual treatment) — all simultaneously, all at scale. Post-Brumadinho, post-GISTM, and under critical-minerals demand growth, the analytic standard has moved. MAGNET4WATER is built for the question mining water actually has to answer.

The 2026 mining water pressure pattern
Critical minerals demand

IRA tax credits, EU CRMA, US-China supply-chain restructuring. Lithium, copper, nickel, cobalt, and rare-earth demand projected to grow 4–6× by 2040. New mines are being proposed in regions where water becomes the binding constraint — not orebody quality.

GISTM tailings standard

Post-Brumadinho and Mariana, the Global Industry Standard on Tailings Management requires public TSF water-balance and seepage disclosure. Auditable, traceable, and updated annually — the days of internal-only seepage models are over.

Closure bond inflation

Closure cost estimates are being revised upward as climate change extends required active-management horizons. Bond markets and regulators are pricing this in — quantitative pit-lake and ARD models are now what defends the bond calculation.

Insurance retreat

Major reinsurers have pulled back from tailings dam coverage. Self-insurance and captive arrangements increasingly require operator-grade quantitative water-risk analysis — not third-party assurances.

Arid-region water rights

Atacama lithium, Chilean copper, Mexican silver, US Southwest copper. Mining water use competes directly with communities and agriculture. Curtailment orders arrive with little notice; defending the operation requires quantitative basin-scale analysis.

FPIC & community consent

Canada, Australia, and parts of Latin America are codifying Free, Prior, and Informed Consent into law. Indigenous and downstream communities expect transparent water-impact analysis — communicable visualizations, not internal reports.

These pressures arrive simultaneously across operating sites, expansion projects, closure portfolios, and new prospects — in jurisdictions on six continents. The analytic infrastructure has to scale with them.

What Sets MAGNET Apart

Four architectural decisions that map directly to the technical reality of mining water.

⚙️

The full hydrogeology stack.

USGS MODFLOW 6 for 3D flow. MT3DMS multi-species reactive transport for ARD, metals, cyanide, sulfates, selenium. MODPATH particle tracking for pit capture zones and source-receptor backtracking. SEAWAT variable-density for brine, hypersaline, and density-driven plumes. T-PROGS transition-probability geostatistics for fracture networks, alteration zones, and heterogeneous geology. The full federal-science stack in one cloud-native platform — not assembled across disconnected vendor tools.

🏞️

Pit-lake closure, coupled.

When a pit is closed and groundwater rebounds, the resulting pit lake is a coupled lake-aquifer system. MAGNET's Level-3 coupling solves lake stage as a solution variable jointly with the 3D aquifer flow — the mathematically correct representation for pit-lake recovery. Closure water-quality predictions over 50–100+ year horizons rest on whether the lake-aquifer coupling is solved correctly — not approximated with a fixed-head boundary.

📈

Multi-decade closure forecasting.

Closure modeling routinely projects 50–100+ years post-operation. Historical climatology is no longer defensible for bond calculation. CMIP6 downscaled climate scenarios are already integrated into SwaNET for surface water balance and recharge forcing into IGW-NET. The closure bond defense rests on a documented climate scenario, not on the assumption that the next century looks like the last one.

🛡️

Confidential + transparent Observatory.

Enterprise tier with hardware-enforced confidential computing protects resource estimates, dewatering schedules, and competitively sensitive information. The same platform supports public-facing observatory pages for FPIC community consultations, ESG disclosure, and GISTM TSF transparency — with 3D visualizations stakeholders can actually interpret. One platform, two modes: protect what must be confidential, publish what must be transparent.

Right physics for the question

Mining water spans physically distinct domains across operation, closure, and legacy phases. Each MAGNET platform uses the engine that fits its domain — coupled through documented handoffs of physically-meaningful quantities.

What MAGNET is — and is not

MAGNET4WATER is water-resource, contamination, and source-water modeling infrastructure for mine sites — on the federal-standard engines USGS and EPA themselves use. It is not a mine operations or plant management system (Maptek, Hexagon Mining, Dassault GEOVIA, Datamine), a geotechnical stability analysis tool (PLAXIS, Rocscience Slide, FLAC, GeoStudio SLOPE/W), or an ore-body resource modeling system (Leapfrog, Vulcan, Surpac). Those remain the operations-side, geotechnical-side, and resource-modeling technology stack the mining sector runs on. What MAGNET adds is the water-resource side: groundwater modeling under and around the mine site, pit-lake water balance, tailings seepage and contaminant transport, GISTM water-related compliance documentation, and closure-planning analytical infrastructure for the multi-decade post-mining horizon — on engines that survive both regulatory review and the litigation that follows.

Pain Points & MAGNET Solutions

1

Dewatering schedule reliability

Dewatering rates drive pumping infrastructure sizing, processing-water availability, and downstream ecological commitments. Model-vs-reality reconciliation needs continual re-calibration as the pit deepens and fracture-network geometry reveals itself

MAGNET: MODFLOW 6 with T-PROGS heterogeneous-K realizations; UCODE automatic calibration against monitoring-well drawdown observations; streaming 3D visualization of the cone of depression as the model runs. Operations teams steer the model against observed data — not wait weeks for a contractor re-calibration.

2

ARD/AMD source-receptor analysis

Acid rock drainage from waste rock dumps, exposed pit walls, and tailings is the canonical multi-decade contamination problem. Regulators want quantitative source attribution and receptor exposure; opposing experts will challenge every assumption

MAGNET: MT3DMS reactive transport with sorption (equilibrium or rate-limited) and first-order decay; MODPATH particles for source backtracking from compliance monitoring wells. Defensible source-receptor analysis on engines opposing counsel cannot disqualify. The same architecture won the Mika Meyers groundwater contamination case.

3

TSF seepage under GISTM disclosure

The Global Industry Standard on Tailings Management requires public TSF water-balance and seepage analysis — auditable, traceable, updated annually. Internal-only seepage models do not satisfy the disclosure requirement

MAGNET: Tailings water balance through the coupled SwaNET-IGW-NET architecture; seepage through MODFLOW 6 with explicit unsaturated-zone treatment; sulfate / metals / process-chemistry transport through MT3DMS. Publish the disclosure-grade analysis to a public observatory; protect the underlying competitively-sensitive details through confidential-computing controls.

4

Pit-lake closure water quality

A pit closes; groundwater rebounds; a lake forms. What's its water chemistry in 50 years? In 100? Bond holders, regulators, and downstream communities all want the answer with documented climate assumptions and uncertainty quantification

MAGNET: Level-3 coupled lake-aquifer modeling with pit-lake stage as a solution variable, jointly with the 3D aquifer. MT3DMS for solute mass balance; CMIP6 climate forcing for the multi-decade horizon. Closure modeling on the mathematically correct lake-aquifer coupling — not approximated with fixed-head simplifications.

5

FPIC & community consultation

Indigenous communities, downstream stakeholders, and host governments expect transparent water-impact analysis with visualizations they can actually interpret. Tabular reports and internal models do not build trust

MAGNET: Streaming 3D visualizations of dewatering cones, plume migration, capture zones, and pit-lake evolution — produced as the simulation runs. Publish to a community-facing observatory page with an AI-generated explanatory report grounded in the model. Stakeholders see the same evidence the operations team sees.

6

ESG disclosure under quantitative review

CDP Water Security, SEC climate rule, CSRD, TCFD, S&P Global Mining ESG — water-risk disclosure is now reviewed by analysts with quantitative expectations. "Trust us" answers no longer pass investor screens

MAGNET: The same models that support operations and closure produce disclosure-grade outputs: water-balance Sankey diagrams, basin-scale availability projections, contamination plume forecasts. One consistent representation across operations, closure, and disclosure — not three different consultant deliverables that contradict each other.

Strategic Value

For mining executives, the architectural commitments translate into three balance-sheet dimensions: closure bond defensibility — defensible quantitative analysis under CMIP6 scenarios that survives regulator and bond-market scrutiny; operating-license preservation — transparent FPIC-grade community engagement on the same platform that runs operations; and insurance underwriting position — operator-grade quantitative water-risk analysis for captive and self-insurance arrangements in a market where reinsurers have retreated.

For the technical teams, the architectural commitments translate concretely: reduce per-site engagement cost through the preprocessed global base and full USGS hydrogeology stack already loaded; support GISTM, ICMM, and CDP disclosure through the same models that drive operations; improve closure-horizon defensibility through documented CMIP6 forcing; and inform community trust through transparent observatory publication of analyses they can interpret.

Proven for Complex Contamination

Three analog deployments demonstrating the architectural patterns that apply to mining: complex contamination remediation, defensible litigation analysis, and portfolio-scale legacy site triage.
