You Can’t Manage What You Can’t See

Most mines know their total tonnage, but not the true value within it. Hidden variability, misplaced material, and incomplete data keep millions locked in uncertainty.

Every Misplaced Load Is Lost Value

When a truck dumps in the wrong spot, ore quality and tonnage tracking fall apart. Misplacement hides recoverable value and skews forecasts before the material ever reaches the mill.

Average Grades Hide Real Variability

A stockpile might look uniform, but grade and hardness often vary block by block. Without a clear view of what sits where, blending and recovery targets drift off course.

Different Teams, Different Truths

Geology, planning, and operations each work from their own models. Data misalignment leads to conflicting forecasts and poor confidence. One unified stockpile model restores clarity across every team.

Turn Uncertainty Into Insight: How NTWIST’s Stockpile Assessment Works

Gather Site Data

Aerial view of multiple haul trucks on intersecting mine roads, each marked with GPS tracking indicators.

We start by collecting the information you already have. This includes fleet and dispatch data, geological block models, and topographical surveys of your stockpiles. You can provide these as exported files or shared datasets. No integration or setup is required.

Rebuild the Stockpile Digitally

Color-coded 3D model of a stockpile displaying gradient contour lines and numeric density values for real-time material analysis.

Our team processes your data through OreMax to create a digital representation of your stockpile. This model reveals where each tonne originated, where it sits today, and how grade and hardness vary throughout.

Analyze Risk and Opportunity

Side-by-side view of a haul truck being loaded with ore by an excavator and then dumping it, overlaid with digital gridlines representing tracking technology.

We examine the data to identify areas of misrouting, hidden variability, and untracked material movement. The analysis highlights where losses occur and where unrealized value can be recovered.

Receive Your Assessment Report

You receive a clear, visual report that shows what is really happening inside your stockpile. It outlines where losses are likely occurring and where the most significant value can be recovered.

Review the Results Together

Your Stockpile Assessment Is Powered by NTWIST’s OreMax

OreMax is the AI-driven stockpile modelling system behind every NTWIST Assessment. It reveals where value is being lost today and how to keep it from slipping away tomorrow.

Model the Full Picture

OreMax rebuilds your stockpile at a granular level using data from surveys, dispatch logs, and material history. It exposes the true grade, hardness, and variability across every zone.

 

Detect and Prevent Loss

The system highlights inconsistencies in material movement and grade so teams can act before dilution, misplacement, or recovery issues occur.

Unify Teams Around One Truth

OreMax becomes a shared model for geology, planning, and operations. Every decision is based on a single, verified source of data.

Scale Beyond the Assessment

When you are ready to move beyond the initial assessment, OreMax continues working for you, providing ongoing visibility and value recovery across your operation.

We Work With the Data You Have

Whether your data lives in spreadsheets, survey files, or dispatch systems, we can use it. The Stockpile Assessment adapts to your site’s current data environment, no integrations or setup required.

Leading Mines Are Already Finding Millions in Hidden Value

Our Stockpile Assessment is helping operations uncover misplaced material, quantify hidden tonnage, and reveal blending opportunities that were invisible before. The results speak for themselves.

Cerro Corona Builds a Verified View of Stockpile Value

Cerro Corona lacked trusted visibility due to missing haul data and rehandles. NTWIST used OreMax to rebuild the stockpile digitally and map confidence by zone.

 

The site gained a verified high resolution view of composition that aligned with internal grades within 95 percent confidence. Planners blend with clarity and reduce reconciliation risk.

Results Delivered:

  • Verified alignment within 95 percent confidence
  • Spatial confidence mapping for copper and gold zones
  • More reliable blending and forecast accuracy

Brazilian Mine Prevents $2 Million in Losses Through Live Stockpile Visibility

A Brazilian gold mine struggled with misroutes and untracked rehandles that distorted stockpile value. NTWIST deployed OreMax to create a live model that tracked composition and movement in real time.

 

The system exposed misplaced material and unified data across teams. The operation prevented an estimated 2 million dollars in losses and improved throughput planning.

Results Delivered:

  • Real time visibility into stockpile composition and status
  • Early detection of misrouted ore and waste
  • Estimated 2 million dollars in losses prevented

Chosen by Mining and Processing Leaders Who Demand Results

From gold miners to downstream refiners, NTWIST gives industrial teams control over their data - and their margins.

By highlighting performance gaps and surfacing new benchmarks, NTWIST is giving our team the clarity needed to move beyond intuition and toward measurable improvement. We're now in a stronger position to define and pursue the next phase of operational excellence.

Having NTWIST independently validate our stockpile model gave us added confidence that our current estimates are sound, and that we’re well-positioned for the transition to stockpile-only operations.

Frequently asked questions

What’s included in the Free Stockpile Assessment?

Our team will review your existing data sources (like GPS logs, dispatch records, and plant feed data) to identify gaps, inconsistencies, or untapped value. You’ll receive a summary of findings with suggested areas for improvement.

Can this system track and differentiate between multiple stockpiles across the site?

Yes. Our system maps and monitors all tracked stockpiles individually, offering site-wide coverage whether you're managing satellite pits, ROM pads, or mill feed stockpiles. This helps reduce reliance on manual handovers and improves accountability.

How does this impact coordination between mine and plant operations?

By linking geological intent with actual haul activity, our model improves the feedback loop between planning and execution. Dispatch, mill operators, and technical services all gain access to the same live view - supporting faster, more aligned decisions across departments.

What kind of data do we need to get started?

At a minimum, we typically need access to haul cycle data (from FMS or dispatch logs), basic stockpile naming conventions, and a connection to your grade control or block model outputs. The cleaner your source data, the faster we can configure and tune the system.

Does this system replace dispatch or FMS?

No - it works alongside your existing systems. Think of it as an operational intelligence layer that adds context to what’s already being recorded. It doesn’t interfere with your control systems, and it’s designed to pull data, not push commands.

What sort of savings or efficiency gains have others seen?

Several NTWIST deployments have demonstrated tangible gains. For example, in a digital twin implementation at a gold mine in Brazil, NTWIST’s system helped prevent an estimated $2 million in ore losses through real-time misrouting detection and unified stockpile visibility. In another case, an AI-driven optimization model delivered measurable improvements during 42% of operating hours, with 17% of off-spec hours corrected, directly boosting stability and profit.

Can we customize the stockpile model to match our naming logic and site layout?

Absolutely. NTWIST’s solution is designed to align with how your team already thinks about stockpiles. You define the naming structure, and we configure the logic accordingly - no rigid frameworks to work around.

Is this tool only useful for large or complex operations?

No. Even mid-sized sites benefit from more accurate material tracking. Whether you're juggling multiple pits or just trying to better manage a few stockpiles feeding a single plant, the visibility and accountability it provides pays off.

How quickly can this be deployed and provide value?

Most pilots are configured in a matter of weeks. Once live, teams typically start seeing value within the first production cycle - especially when used to inform blending or validate stockpile assumptions ahead of a campaign.

Does this help with compliance or reconciliation efforts?

Yes. Our model can be configured to support reconciliation workflows by offering an auditable trail of material movement and estimated composition. This supports both internal reporting and external compliance where required.
