About us

Technical judgment you can audit.

Geology and geotechnical services for open-pit and underground mines across the Great Basin and the Mountain West.

We stay with your site from exploration to post-closure monitoring.

Our approach

We collect the data, build the model and stand behind the decision.

Drywash Geoscience exists so your operation can decide with enough information: no more study than you need, and no less than the decision demands.

  • A technical, specialized firm, with geology and engineering behind every call.
  • The capacity to cover the whole chain, with one lead per project.
  • Reliable: every stage is documented, measured and delivered with a traceable record.

Three capabilities, one team

  1. Exploration

    Mapping, sampling and drilling QA/QC so you know what's there, and how sure you can be.

  2. Geotech

    Slope and underground stability, with the instruments that prove the design in the ground.

  3. Reclamation

    Reclamation plans, chemical stability and post-closure monitoring until conditions settle.

What we solve

A study can start with a single question.

We start from the decision behind your question, not from a report template.

Pick a question to see how we'd tackle it.

Can I steepen this slope without taking on more risk?

We characterize the rock mass, run the stability analyses and give you a defensible angle with its factor of safety, plus the monitoring plan that keeps it valid.

How much water am I going to have to pump?

We build the groundwater model for your site and forecast inflows, so pumping costs are in the plan before they turn into a surprise.

View related service
Will my tailings facility handle the next raise?

We review the design, phreatic surface control and instrumentation, with an independent stability review.

View related service
What's it going to cost to close this mine?

We prepare or update your reclamation plan with a cost estimate backed line by line, plus the concurrent reclamation that lowers the final bill.

View related service
Is it worth drilling these claims any further?

We plan the program, control data quality and deliver an interpreted geologic model with its uncertainty stated.

View related service
Is my ground support actually right for the ground?

We classify the rock mass heading by heading, then size and verify the support with real convergence readings.

Is this asset worth the asking price?

We review resources, geotechnical assumptions and environmental liabilities, and separate what's supported from what's wishful thinking.

Stage by stage

We can step in at any point in the chain.

You decide where we start and how far we go. Every stage can be contracted on its own.

How we work

Five stages, one lead.

That's how we work when the study runs start to finish. If you've already got part of it done, we jump in wherever you need us.

  1. 1

    Define the decision

    Before we propose a scope, we ask what decision rides on the study: keep drilling, steepen the slope, approve the next dam raise. We size the work to that decision, not to fill out a report.

  2. 2

    Field program

    We collect the data on site with chain of custody and digital logging: mapping, sampling, lab testing, and installing the instruments you'll need later on.

  3. 3

    Model and analysis

    We bring the data into the geologic, geotechnical or groundwater model the job calls for, then run the analyses. Every result comes with its uncertainty range, not a single number on its own.

  4. 4

    Recommendation

    We deliver the recommendation in terms of the original decision: what to do, when it stops being valid, and what risk you're accepting by following it.

  5. 5

    Ongoing monitoring

    No geotechnical criterion holds forever. We leave you a monitoring plan with trigger action response plans, reading frequency, and the steps to take when a measurement goes outside the expected range.

Why DRYWASH GEOSCIENCE?

What your operation gains by working with us.

It's not just about having the credentials. It's about what's left once the report is delivered.

Judgment you can defend

Every recommendation cites the data behind it and the range where it stops holding up.

Boots on the ground

The person who signs the report is the one who was in the pit, not someone who reviewed it from an office.

Truly independent

We don't sell equipment or build what we recommend, so our advice has no other agenda.

Uncertainty out in the open

We tell you what we don't know and what it would cost to find out, instead of hiding it behind a single number.

Deliverables you can use

Reports that stand up to an audit, and drawings your site team can actually follow.

Know-how that stays

We leave your site team understanding the model, not waiting on us to come back.

5 Project stages From the field program to the final report.
8 Service lines Four in geology and four in geotech.
1 Lead per project One senior geologist owns it from start to finish.
Who we are

Who we are, in six answers.

What's worth knowing about Drywash Geoscience in our first conversation.

What we do

Geology, geotech and mine reclamation.

Where we're strongest

Pit slope stability and tailings management, tied together with water and geology.

Who we work for

Large open-pit mines, underground and mid-tier operations, and anyone evaluating or financing a mining asset.

The problem we solve

Making sure an expensive decision rests on evidence, not on someone's gut feeling.

How we do it

Traceable field data, a model with its uncertainty, and monitoring that keeps the call current.

What sets us apart

We don't sell equipment or build what we recommend, so our advice has no other agenda.
