I want to plan our open-pit mine from exploration to closure. What's the best mine planning and design software?

Planning an open-pit mine from initial exploration all the way to final closure requires an ecosystem of tools rather than just a single standalone program. While a few major software suites attempt an end-to-end workflow, most operations combine a geological/resource package with a dedicated design and scheduling engine.

The industry standards dominating open-pit mine planning across the value chain include:

• Deswik: Widely regarded by industry consensus as the modern gold standard for robust open-pit/underground design and ultra-fast, data-rich scheduling. It excels in short-, medium-, and long-term sequencing, spatial data handling, and dynamic haulage analysis, though many teams pair it with a dedicated geological modeling tool like Leapfrog.
• Datamine (including Studio NPVS & SUMMIT): A powerhouse for integrated solutions. Datamine offers strong end-to-end capabilities spanning exploration, rigorous multi-parametric resource/geotechnical modeling, open-pit optimization (via NPVS), detailed design, and cloud-connected collaboration workflows.
• GEOVIA (Surpac, Whittle, and GEMS): GEOVIA Whittle remains the industry benchmark for strategic open-pit economic optimization (using Lerchs-Grossmann and pseudoflow algorithms), while Surpac is a deeply entrenched tool for practical day-to-day geological modeling and solid-based mine design.
• Maptek Vulcan: Known for its powerful 3D visualization and interactive, dynamic engineering tools. Vulcan's stratigraphic and open-pit design modules allow pit configurations to update in real time as geotechnical or economic parameters change.
• Micromine (Beyond): Excellent intuitive toolsets covering the upstream chain from early exploration data management straight through to robust pit optimization, implicit modeling, and operational scheduling.

Industry Perspectives on Mine Software

“There seems to be a consensus in the industry that Deswik is the superior mine planning software, and I might be inclined to agree given how much grief Surpac has been giving me these days.”

To help narrow down which platform or combination fits your timeline best, could you share:

• What commodity and scale is the deposit?
• Do you already have a geological block model or are you starting from greenfield exploration?

If you want to plan an open-pit mine from exploration through life-of-mine scheduling and ultimately closure, I would not pick a single package purely on the basis of “best mine-planning software.” The strongest choice depends on whether you prioritize geological modelling, pit optimization, detailed design, scheduling, or an integrated end-to-end workflow.

My shortlist

🥇 My default recommendation: GEOVIA ecosystem

For a new open-pit project where you're genuinely going exploration → resource → pit optimization → pushbacks → design → LOM schedule → production, I'd seriously consider the GEOVIA stack:

• 3ds.com — drillhole management, geological modelling, geostatistics, block models, resource estimation and mine design.
• 3ds.com — strategic pit optimization, nested shells, economic analysis, pushbacks and LOM optimization.
• 3ds.com — tactical/LOM scheduling, including automated scheduling of open-pit pushbacks and benches.

That separation is actually a strength: Surpac builds the geological/resource foundation, Whittle answers "what should we mine?", and MineSched answers "when/how should we mine it?" GEOVIA explicitly positions these products across geology, strategic planning and tactical scheduling.

Whittle is particularly compelling if the project is still at the economic evaluation / feasibility stage, because it can evaluate alternative pit shells and mine strategies rather than simply producing a geometric pit. It supports both Lerchs–Grossmann and Pseudoflow optimization and incorporates economic variables, blending, cut-off and stockpile optimization.

🥈 If you want one very integrated 3D environment: Maptek Vulcan

maptek.com is probably my strongest alternative.

Its scope is unusually broad: geological modelling, block modelling, geostatistics, mine design, scheduling, optimization, survey, grade control, drill/blast and geotechnical workflows. Maptek describes Vulcan as covering the process from exploration/geological modelling through mine design and scheduling to rehabilitation.

The current Vulcan ecosystem also includes an Open Pit Optimisation add-on and Scheduling Suite, while its Gantt Scheduler can sequence activities, level resources and link schedules directly to 3D mine entities.

I'd lean toward Vulcan if your priority is:

"I want my engineers and geologists working in one powerful 3D mine environment rather than stitching lots of specialist applications together."

🥉 If scheduling is the heart of the problem: Deswik

I'd put Deswik very high on the evaluation list if your mine is going to have complicated scheduling constraints—multiple mining fronts, fleets, processing constraints, stockpiles, blending, ramp-up, multiple pits, etc.

For a mature operation, sophisticated scheduling can matter more than which package has the nicest geological modelling interface. In that situation, I'd evaluate Deswik alongside GEOVIA and Vulcan rather than automatically selecting a geology-centric package.

What I'd actually build for a new mine

For a serious project, I'd structure the digital workflow approximately like this:

Exploration → drillhole database → QA/QC + compositing → geological interpretation → geostatistics → resource model

Resource → Reserve → block model → geotechnical parameters → mining recovery/dilution → economic assumptions → pit optimization

Strategic planning → nested pit shells → ultimate pit → pushbacks/phases → mining sequence → processing/stockpile strategy → LOM schedule → NPV / IRR / sensitivity analysis

Detailed engineering → bench/berm geometry → ramps and haul roads → mining widths → waste dumps → stockpiles → water infrastructure → plant/infrastructure interfaces

Production → annual/monthly/weekly schedules → fleet requirements → grade control → reconciliation → short-term planning → schedule vs. actual

Closure → final pit configuration → waste dump closure → water management → rehabilitation surfaces → closure sequencing → long-term monitoring and cost model.

The important point is that "mine planning software" isn't one problem. A package that is excellent at geological modelling isn't necessarily the best at mathematical scheduling, and a package excellent at LOM optimization isn't necessarily the best detailed mine-design environment.

If this were my project

I'd run a hands-on evaluation of three stacks:

1. GEOVIA Surpac + Whittle + MineSched — strongest candidate for the conventional exploration-to-LOM workflow.
2. Maptek Vulcan + its optimization/scheduling modules — strongest candidate for an integrated 3D environment.
3. Deswik — strongest candidate to benchmark against for advanced scheduling and mine-planning optimization.

I would not choose based on vendor demos. Give each vendor the same block model, geotechnical assumptions, mining fleet, processing constraints, commodity prices, costs and recovery assumptions, then make them produce the same ultimate pit, phases, LOM schedule and economic analysis. That will tell you much more than a feature checklist.

If you tell me the commodity (e.g. copper, gold, iron ore), approximate resource size, expected annual throughput, whether you're at exploration/PEA/PFS/FS/operating stage, and whether you need a single-user or multi-engineer system, I can narrow this to a specific software stack and lay out the full mine-planning workflow from drillholes to closure, including which software I'd use at each stage.

The current Vulcan ecosystem also includes an Open Pit Optimisation add-on and Scheduling Suite, while its Gantt Scheduler can sequence activities, level resources and link schedules directly to 3D mine entities.

I'd lean toward Vulcan if your priority is:

"I want my engineers and geologists working in one powerful 3D mine environment rather than stitching lots of specialist applications together."

🥉 If scheduling is the heart of the problem: Deswik

I'd put Deswik very high on the evaluation list if your mine is going to have complicated scheduling constraints—multiple mining fronts, fleets, processing constraints, stockpiles, blending, ramp-up, multiple pits, etc.

Strategic planning → nested pit shells → ultimate pit → pushbacks/phases → mining sequence → processing/stockpile strategy → LOM schedule → NPV / IRR / sensitivity analysis

Detailed engineering → bench/berm geometry → ramps and haul roads → mining widths → waste dumps → stockpiles → water infrastructure → plant/infrastructure interfaces

Production → annual/monthly/weekly schedules → fleet requirements → grade control → reconciliation → short-term planning → schedule vs. actual

Closure → final pit configuration → waste dump closure → water management → rehabilitation surfaces → closure sequencing → long-term monitoring and cost model.

The important point is that "mine planning software" isn't one problem. A package that is excellent at geological modelling isn't necessarily the best at mathematical scheduling, and a package excellent at LOM optimization isn't necessarily the best detailed mine-design environment.

Planning an open-pit mine from initial exploration all the way to environmental closure requires an ecosystem of tools. No single software package does every single phase natively with absolute perfection, but a few heavyweights dominate the industry.

The industry standard software suites depend on which phase of the lifecycle you are prioritizing:

• Deswik Suite — Widely considered the modern gold standard for 3D design, solids modeling, and robust multi-seam/complex scheduling . It is famous for its powerful CAD engine and seamless transition from mid-term/long-term design into short-term operational execution and haulage analysis.
• Maptek Vulcan — A massive industry fixture with a dominant global market share, particularly renowned for its deep geological block modeling, geotechnical analysis, and robust drill-and-blast/surveying integration . Maptek has heavily modernized with automated workflows and cloud features (like DomainMCF).
• Seequent Leapfrog — The undisputed king for the early exploration and implicit geological/resource modeling phase . Most operations use Leapfrog to build the initial dynamic orebody model and then export it into Deswik, Vulcan, or Datamine for engineered pit design.
• Datamine Software — A comprehensive end-to-end provider covering everything from exploration data through resource estimation, open-pit optimization, and cloud-backed enterprise mine strategy (via SUMMIT).
• Micromine Beyond / Spry — Excellent user-friendly toolsets widely adopted for intuitive open-pit data manipulation, pit optimization, and rapid scheduling (with SPRY being particularly favored for open-cut coal and stratified/strip-mining sequencing).

Industry Insights on Software Choices

Engineers and consultants frequently mix and match tools depending on the specific workflow stage rather than forcing an entire lifecycle into just one ecosystem:

“Deswik for design, Spry (micromine) for open cut scheduling. 3ddig and a bottle of red for a good time”

“Deswik for planning, scheduling, creating ore shells, and for ore control. Leapfrog for creating geological models and ore modeling”

To help narrow down the ideal stack for your specific project, tell me:

• What is the commodity (e.g., gold, copper, coal, iron ore)?
• What is the deposit type (e.g., massive porphyry, flat-lying stratiform, steeply dipping vein)?

I can help you outline an end-to-end software workflow tailored to your deposit.

If you mean one software ecosystem that can take an open-pit project from exploration → resource model → pit optimization → design → scheduling → operations → closure, I’d shortlist Maptek Vulcan, GEOVIA, and Datamine, rather than looking for a single program that does every task equally well.

My top choices

1. My default recommendation: Maptek Vulcan + Evolution

maptek.com is probably where I'd start for a greenfield open-pit project.

Vulcan covers geological and resource modelling, block modelling, geostatistics, geotechnical work, open-pit design, optimization and scheduling. Its Open Pit Design tools handle benches, berms, slopes, ramps, dumps and mineable solids, while the Open Pit Optimisation module provides pit-limit and cut-off-grade optimization.

For strategic and life-of-mine scheduling, Maptek's Evolution suite adds short-, medium-, long-term and strategic scheduling.

The big advantage is workflow continuity: exploration data can become a geological model, then a resource/block model, then optimized pit shells, phases/pushbacks, detailed pit designs and finally schedules. That reduces the painful "export from Software A → manipulate in B → import into C" problem.

2. If economics and strategic optimization are paramount: GEOVIA

GEOVIA Whittle is one of the strongest choices for strategic open-pit planning. It is specifically designed to evaluate economic viability, pit optimization, long-term strategy, scheduling, costs, recoveries, blending, cut-off grades and stockpile optimization.

I'd particularly consider this combination if you're doing a feasibility study / investment decision where NPV, project sequencing, cut-off strategy and sensitivity analysis are the central questions.

An important current point: Dassault Systèmes says Whittle continues to be developed, including a 2026 release, rather than being discontinued in favor of its newer 3DEXPERIENCE tools.

3. Datamine

Datamine is worth serious consideration if you want a highly capable geology/resource-to-mine-planning environment and your team already has experience with it.

I'd put it in the same serious evaluation group as Vulcan and GEOVIA rather than treating it as a second-tier alternative.

What I'd actually build for a new mine

For a greenfield open pit, I'd structure the digital mine-planning workflow approximately like this:

1. Exploration → drillhole database → QA/QC → geological interpretation → structural/domaining model

2. Resource → compositing → variography → estimation → block model → classification → density / metallurgy

3. Economic model → metal prices → recoveries → mining costs → processing costs → G&A → royalties/taxes → sustaining capital → discount rate

4. Pit optimization → geotechnical sectors → bench/berm parameters → ramp constraints → mining costs → processing constraints → recoveries → optimized pit shells → sensitivity cases

5. Mine design → ultimate pit → pushbacks/phases → benches → ramps → haul roads → ore/waste dumps → stockpiles → infrastructure exclusion zones

6. Scheduling → mining blocks → equipment/productivity → mining capacities → plant capacity → blending → stockpile strategy → cut-off strategy → annual/monthly schedule → LOM cash flow and NPV

7. Operational planning → annual → quarterly → monthly → weekly → daily plans → grade control → reconciliation → survey/as-built comparison → plan-versus-actual feedback

8. Closure → final landform → waste dump closure → tailings closure → pit lake / pit-wall strategy → water management → reclamation → monitoring → closure cost and schedule

Vulcan is particularly attractive for this workflow because its current documentation explicitly positions the platform from exploration and geological modelling through mine design, scheduling and rehabilitation.

One important caveat

I wouldn't choose software purely on the feature checklist.

For a real mine, the quality of the optimization and scheduling methodology, geotechnical assumptions, equipment/productivity models, economic model, and engineer's workflow matters much more than whether a package has "AI," 3D graphics, or 200 additional buttons.

I'd also avoid trying to force closure planning entirely into mine-planning software. Mine software should provide the final surfaces, material quantities, sequencing and economic inputs, but closure usually needs dedicated water, geochemical, geotechnical, environmental and reclamation modelling as well.

If I were selecting today

My initial shortlist would be:

1. Maptek Vulcan + Evolution — best candidate for an integrated end-to-end open-pit workflow.
2. GEOVIA Whittle + the GEOVIA design/scheduling stack — particularly strong for strategic optimization and feasibility studies.
3. Datamine — strong alternative, especially if your geology/resource team already uses Datamine.
4. Hexagon MinePlan — particularly worth evaluating for a large operating mine where planning needs to connect closely with operational technology.

If you tell me the commodity (copper, gold, iron ore, lithium, etc.), approximate deposit size, whether this is greenfield or an operating mine, and whether you're at exploration, PEA, PFS, or feasibility stage, I can narrow this to a specific software stack and workflow, including which modules I'd license at each stage and where I'd use separate tools.

1. My default recommendation: Maptek Vulcan + Evolution

maptek.com is probably where I'd start for a greenfield open-pit project.

Vulcan covers geological and resource modelling, block modelling, geostatistics, geotechnical work, open-pit design, optimization and scheduling.

If I were selecting today

My initial shortlist would be:

Planning an open-pit mine from initial exploration all the way to final closure requires an ecosystem of tools rather than just a single program. While software can handle specific phases brilliantly, finding a "best" option depends on whether your priority is seamless data flow across the entire lifecycle or best-in-class performance in a specific engineering domain.

The industry standards dominating open-pit mine planning and design are categorized below by their strengths across the mine lifecycle.

Top Integrated Suites (End-to-End Lifecycle)

• Deswik : Widely considered an industry heavyweight for bridging 3D design and dynamic scheduling. It excels in generating solids-based designs, interactive pit/dump layouts, haul road design, and robust short-to-long-term scheduling. Its data-centric framework ties mine design directly to the schedule so changes propagate efficiently.
• Hexagon MinePlan : A comprehensive life-of-mine platform scaling smoothly from exploration data and block modeling all the way to short-term tactical engineering, drill-and-blast design, and operational fleet management. It is heavily favored in large-scale, data-intensive operations.
• Datamine Studio : Provides a fully modular suite covering exploration, implicit modeling, pit optimization (using tools like Studio NPVS+), detailed open-pit design, and production scheduling. Datamine's connected planning bundles and governance tracking make it a strong lifecycle contender.

Best for Exploration & Geological Modeling

• Seequent Leapfrog Geo : The undisputed gold standard for rapid, dynamic 3D implicit geological and resource modeling. It handles fast-paced updates during exploration drilling cycles much faster than traditional explicit wireframing tools.
• GEOVIA Surpac (Dassault Systèmes): Long-time staple for efficient resource estimation, block modeling, and large-scale open-pit design. It integrates tightly with production scheduling tools like MineSched.

Best for Detailed Scheduling & Optimization

• Maptek Vulcan / Evolution : Maptek's Vulcan is a robust 3D CAD/design environment for interactive pit design, while Evolution handles advanced short- and long-term scheduling, helping minimize dilution and operational bottlenecks.
• RPMGlobal MinePlanner : Noted for automated, script-free reserving, destination scheduling, and an integrated product optimizer that balances complex blending and material movement targets.
• Spry (by Micromine) : Highly popular for rapid, attribute-driven open-cut scheduling, often paired by operations teams with a separate CAD design engine.

Industry Insights on Software Combinations

“For design work which is generating solids for scheduling - Deswik. For the actual scheduling - Spry. I feel like Spry has reach a point of critical mass.”

“Deswik for planning, scheduling, creating ore shells, and for ore control. Leapfrog for creating geological models and ore modeling.”

To help narrow down the ideal tool stack for your specific project, tell me:

• What is the commodity and deposit type (e.g., massive copper porphyry, layered coal/stratigraphic, narrow vein)?
• What stage is the project currently in (greenfield exploration vs. active scoping/feasibility study)?

For an open-pit mine planned from exploration through closure, there usually is not one “best” software. The strongest workflows use a suite covering geology, resource estimation, pit optimization, mine design, scheduling, economics, operations, and closure.

A typical best-in-class stack looks like this:

My shortlist for a new open-pit project

1. Best overall integrated choice: Deswik ecosystem

For a new open-pit operation where the priority is mine design → scheduling → execution, Deswik is one of the strongest choices. It combines CAD-based mine design, reserving, drill/blast workflows, and scheduling in one environment.

Best for:

• Copper, gold, iron ore, lithium, aggregates
• Large open pits
• Teams needing strong engineering workflows

2. Best geology-heavy workflow: GEOVIA Surpac + Whittle + MineSched

A very common combination when geology and resource modeling are central. Whittle is especially well known for strategic pit optimization.

Best for:

• Exploration-led companies
• Feasibility studies
• Deposits where geological modeling drives decisions

3. Best for very large operations: Vulcan + specialist planning tools

Maptek Vulcan is widely used for large and complex mine modeling and visualization workflows.

Best for:

• Large multi-disciplinary technical teams
• Complex orebody modeling
• Operations already standardized on Vulcan

4. Best for advanced strategic optimization

For projects where the main question is “what schedule maximizes value under constraints?”, specialized optimizers such as Deswik GO or Minemax-style optimization tools can be valuable.

---

If I were setting up a new open-pit mine study today

A practical setup would be:

1. Leapfrog Geo or Surpac → exploration database and geological model
2. Whittle / Deswik GO → pit optimization and economics
3. Deswik → final pit design, reserves, schedules, drill/blast design
4. HAULSIM or Deswik LHS → fleet and haulage validation
5. GIS/environmental tools → closure, permitting, water, rehabilitation

For a greenfield mine from discovery to closure, I would lean toward Deswik + a strong geological modeling package rather than trying to force everything into a single platform.

The “best” choice depends heavily on your commodity (gold/copper/iron/lithium/etc.), country, mine size, expected annual tonnes, and whether this is a feasibility study or an operating mine. If you share those, I can suggest a more specific software stack and workflow.

For an open-pit mine planned from exploration through closure, there usually isn’t one “best” software package. The best choice is typically an integrated stack covering:

1. Exploration & resource modeling
2. Geological modeling and block models
3. Pit optimization
4. Life-of-mine (LOM) scheduling
5. Detailed pit/road/dump design
6. Production planning and reconciliation
7. Closure and reclamation planning

The leading options are:

My typical recommendation by project stage

Greenfield exploration → feasibility study

• Geological database + resource modeling:
  • GEOVIA Surpac or HxGN MinePlan Resource Geo
• Pit optimization:
  • GEOVIA Whittle or HxGN MinePlan Strategic
• Economic scenarios:
  • Whittle, MinePlan, or similar optimization tools
    

Feasibility → construction decision

• Add:
  • Detailed pit shells
  • Pushbacks/phases
  • Haul roads
  • Waste dumps
  • Stockpiles
  • LOM schedules

Good combinations:

• Hexagon MinePlan suite for an integrated environment
• GEOVIA + Deswik for many large studies (Whittle for strategy, Deswik for detailed design/scheduling)

Operating mine

• Deswik is particularly strong for linking designs and schedules and handling detailed planning horizons.
• Hexagon is attractive if you also want integration with mine operations technologies.

If I were selecting a stack for a new open-pit mine today

For a large copper/gold/iron ore project:

• Resource geology: HxGN MinePlan Resource Geo or GEOVIA Surpac
• Pit optimization: GEOVIA Whittle or MinePlan Strategic
• LOM scheduling: Deswik Planning or MinePlan OP Engineering
• Detailed design: Deswik Spatial or MinePlan 3D CAD
• Production reconciliation: integrated mine operations platform

For a small-to-medium feasibility study, I would prioritize:

1. Geological model quality
2. Pit optimization capability
3. Scheduling flexibility
4. Ease of exchanging data with consultants

The “best” package depends heavily on commodity, mine size, deposit geometry, jurisdiction, and whether you are doing a study or running an operation.

If you tell me:

• commodity (gold, copper, lithium, iron ore, coal, etc.)
• approximate annual production
• greenfield vs operating mine
• study stage (exploration, PEA/scoping, feasibility, production)
• budget/team size

I can suggest a more specific software stack.

Planning an open-pit mine from initial exploration to final closure requires an ecosystem of tools rather than a single silver-bullet program. Because no single software package natively excels at every single sub-discipline (from rapid implicit geological modeling to multi-million block optimization and geotechnical stability), most operations use an integrated workflow combining two or three dominant platforms.

The industry standards categorized by their strengths across the mine lifecycle include:

• Deswik Suite
  • Best for: Enterprise-level integrated mine planning, detailed 3D design, and short-to-long-term scheduling.
  • Lifecycle Stage: Development, production design, and active scheduling.
  • Why it shines: Deswik has largely disrupted traditional players by offering a powerful, data-driven platform with robust change-propagation and solid modeling capabilities that feed directly into production sequencing.
• Maptek Vulcan
  • Best for: End-to-end 3D geological modeling, interactive open-pit/stratigraphic design, and survey reconciliation.
  • Lifecycle Stage: Exploration, resource estimation, and day-to-day operational engineering.
  • Why it shines: Highly modular with powerful toolsets for pit optimization, drill-and-blast layouts, and seamless integration with survey data and scheduling engines.
• Seequent Leapfrog Geo
  • Best for: Rapid, implicit 3D geological and orebody modeling.
  • Lifecycle Stage: Exploration and resource definition.
  • Why it shines: It is the industry gold standard for fast updates as new drillhole data rolls in, easily linking downstream to major engineering packages like Deswik, Datamine, or Vulcan.
• GEOVIA Surpac & Whittle
  • Best for: Strategic pit optimization (Whittle) and comprehensive resource management/design (Surpac).
  • Lifecycle Stage: Conceptual studies, pit limit optimization, and life-of-mine (LOM) strategic planning.
  • Why it shines: Whittle remains legendary for robust pseudoflow/cash-flow economic optimization, while Surpac is globally ubiquitous for practical mid-to-large-scale bench and ramp design.
• Hexagon MinePlan
  • Best for: Large-scale enterprise operations and heavy-duty schedule optimization.
  • Lifecycle Stage: Long-range strategic planning through active mine operations.
  • Why it shines: Features the MinePlan Schedule Optimizer (MPSO) which factors in complex haulage, blending, and stockpiling constraints to maximize net present value (NPV).
• Datamine (Studio RM & NPVS+)
  • Best for: Resource evaluation, open-pit optimization, and integrated scheduling.
  • Lifecycle Stage: Feasibility through operational scheduling.
  • Why it shines: Their Studio NPVS+ tool accelerates the jump from resource model to maximized NPV mine schedules.
• Rocscience Suite (Slide3 / RS3)
  • Best for: Advanced geotechnical slope stability and closure landform analysis.
  • Lifecycle Stage: Design validation, operational monitoring, and closure/reclamation planning.
  • Why it shines: While not traditional "mine planners," you will need a dedicated geotechnical package to import your pit shells from Deswik or Vulcan to ensure safe inter-ramp angles and stable closure surfaces.

To help narrow down the ideal software mix for your specific project, could you share:

• The commodity you are targeting (e.g., bulk commodities like coal/iron ore vs. hard-rock precious/base metals)?
• The current scale and project phase (greenfield exploration vs. active scoping/pre-feasibility study)?

If you want one software ecosystem to take an open-pit project from exploration through mine design, scheduling, operations, and closure, I’d shortlist Deswik, Maptek Vulcan, and GEOVIA. There isn’t one universal winner—the best choice depends heavily on whether you prioritize integrated scheduling, geology/modeling, or strategic optimization.

My ranking for a new open-pit mine

1. Deswik — my default recommendation

For a greenfield open-pit operation, I'd probably start here. Deswik has a particularly strong design → schedule → operational plan workflow. Its Spatial tools cover 3D mine design, modeling, reserving and pit design, while Planning connects designs directly to schedules.

Its newer Deswik NOVA is specifically aimed at open-pit planning, combining mine scheduling, blending and haulage optimization in one workflow.

I'd choose Deswik if your objective is:
Exploration/resource model → pit optimization → pushbacks → detailed pit design → LOM schedule → medium/short-term plans → reconciliation → operations.

2. Maptek Vulcan — excellent geology-to-mine workflow

Vulcan is particularly compelling if your geologists and mining engineers need to work in the same 3D environment. The current Vulcan platform covers exploration/geological modeling, block modeling, geostatistics, mine design, scheduling, optimization, drill & blast, survey and rehabilitation.

That's a major advantage for a greenfield project because you don't want the resource model becoming disconnected from the eventual mine design.

I'd choose Vulcan if: geological modeling and 3D interpretation are as important to you as scheduling.

3. GEOVIA — particularly strong for strategic mine planning

GEOVIA is actually a collection of complementary tools rather than one monolithic application:

• Surpac — drillholes, geology, geostatistics, resource/block models and mine design.
• Whittle — pit optimization, economic analysis, pushbacks, strategic scheduling, blending and stockpile optimization.
• MineSched — tactical/short- and long-term scheduling.

For the "What is the economically optimal way to develop this deposit?" question, Whittle is a particularly strong component. It supports both Lerchs-Grossmann and Pseudoflow pit optimization and can evaluate different strategic scenarios.

What I'd actually deploy

For a serious greenfield project, I wouldn't select software based on the number of features. I'd build the workflow around these stages:

1. Exploration → drillhole database
→ QA/QC
→ geological interpretation
→ geostatistics
→ resource estimation

2. Resource → reserve → block model
→ density/domaining
→ metallurgical assumptions
→ economic parameters
→ modifying factors

3. Strategic study → economic pit optimization
→ revenue/cost assumptions
→ nested shells
→ cut-off strategy

→ rehabilitation
→ closure costs
→ monitoring/post-closure requirements

Deswik and Vulcan are especially attractive because their current product ecosystems explicitly span much of this lifecycle; Deswik, for example, describes its surface-mining solution as covering design/reserving, planning, operations, environmental management and related workflows, including closure planning.

The important caveat

I would not make the software decision until you've established what kind of deposit you're planning.

For example, the ideal stack can be quite different for:

• large copper porphyry
• gold
• iron ore
• lithium
• coal
• nickel
• quarry/aggregate

and whether you're at grassroots exploration, PEA, PFS, FS, construction, or an operating mine.

If you tell me the commodity, approximate resource size, country, project stage, and whether you already have a block model, I can give you a much more concrete software stack and workflow (including which modules to buy, what each should do, and where alternatives like Whittle vs Deswik vs Vulcan fit).

Planning an open-pit mine from initial exploration to final closure requires an integrated ecosystem rather than a single tool, as no single software dominates every single phase from greenfield exploration to post-mining rehabilitation.

The industry standard approach involves pairing a dedicated geological/implicit modeling tool with an end-to-end mine design and scheduling suite.

Phase-by-Industry-Standard Software Stack

• Exploration & Implicit Geological Modeling
  • Leapfrog Geo by Seequent (industry leader for fast, dynamic 3D geological and structural modeling that updates instantly as new drillhole data arrives).
  • Alternatives: Datamine Studio RM, Micromine Origin.
• Pit Optimization, Design, & Scheduling
  • Deswik Suite (widely considered the modern benchmark for integrated design, rigorous data-driven scheduling, and haulage simulation across short- and long-term horizons).
  • Maptek Vulcan (a powerhouse for detailed 3D block modeling, open-pit geometric design, and robust geotechnical/survey workflows).
  • GEOVIA Surpac & MineSched (Dassault Systèmes' globally recognized ecosystem for resource estimation, open-pit design, and production scheduling).
  • Hexagon MinePlan (exceptionally robust for large-scale long-term strategic planning, geostatistics, and operational fleet integration).
• Rehab, Topography Tracking, & Closure
  • Geospatial reality capture and drone surveying platforms like Propeller Aero or DroneDeploy combined with GIS tools to track progressive reclamation, watershed analysis, and post-mining landform stability.

Real-World Insights from Mine Planners

Industry feedback highlights how engineers transition between tools depending on the specific task at hand:

“Deswik for planning, scheduling, creating ore shells, and for ore control. Leapfrog for creating geological models and ore modeling.”

“Short term design work - Vulcan. Any design work which is generating solids for scheduling - Deswik. For the actual scheduling - Spry.”

To help narrow down the ideal software configuration, could you share:

• The commodity type (e.g., precious metals, bulk commodities like coal/iron ore, or industrial minerals)?
• The project scale (junior explorer moving to a PEA/PFS, or an operating enterprise looking to upgrade)?
