Supporting specialties — Built into the main study so you get the complete technical record.
Industries
Three markets. One standard.
Operations where the ground and the water dictate what you can do.
01
Large open-pit mines
Open-pit operations where every hour of downtime has a price tag.
View industry 02
Underground and mid-tier mines
Growing underground operations that need their own technical backing.
View industry 03
Investors and advisors
Anyone evaluating, financing or auditing a mining asset who needs an outside view.
View industry How we work
Five stages. One decision at the end.
We size the scope to the decision you have to make, not to fill out a report.
- 1
Define the decision
What has to be decided, and what evidence it takes.
- 2
Field program
Mapping, sampling and instrumentation you can trace.
- 3
Model and analysis
A model built with its uncertainty stated up front.
- 4
Recommendation
A clear call, with its conditions and its risk.
- 5
Ongoing monitoring
Trigger levels, readings, and who acts when they're crossed.
Why DRYWASH GEOSCIENCE?
What your operation gains by working with us.
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.
