Our Team

Sector-native.
We understand the geology first.
Then we make it clear.

Three decades. 500+ projects. One discipline:
making geology legible to capital.

The Translation

Fluent in the rock.
Fluent in the market.

We are staffed on both sides of the translation: geology- and GIS-trained mapmakers and Leapfrog modellers sitting next to art directors and developers, on the same file — work we have been doing for exploration companies since 1996.
