Translating the language rocks speak with business

GeoSpy is a translator between two languages. 

The language that rocks speak is one of subtlety, complexity and hidden meaning. GeoSpy's principal Darren Holden is an expert geologist who is technically savvy and always delivers an 'outside the square' discovery process. 


The language business speaks is one of value creation, development, milestones and delivery. Darren Holden is a well connected and accomplished corporate raconteur delivering the message of discovery with verve, credibility and honesty. 




Several ASX listed companies focused on:
