GEOSOL

What GEOSOL does

GEOSOL Geologia e Sondagens S.A. is a privately held Brazilian drilling services company headquartered in Belo Horizonte, Minas Gerais, operating as a subsidiary of The Geopar Group. Founded in 1950, the company has accumulated over 70 years of experience providing specialized geological and drilling solutions to the mining and mineral exploration industry, with 7 operating branches across multiple Brazilian states and international operations in multiple countries. Headcount is reported in the 501-1,000 employee range.

GEOSOL's core offering is a portfolio of 9 drilling methodologies — diamond drilling (conventional and wireline), well drilling, reverse circulation, underground drilling, air core/screw core (developed specifically for bauxite), large diameter, heli-drilling, slim drilling, and geophysical profiling — supported by an owned fleet of multi-class rigs and proprietary equipment including the in-house developed Smart Drill. The company deploys third-party Robertson Geologging probes (OPTV, Hi-RAT, Full-Waveform Sonic, Sidewall Formation Density, etc.) for advanced subsurface characterization. ISO 9001, ISO 14001, and ISO 45001 certifications underpin the operational platform.

Commercially, GEOSOL operates a B2B sales-led model targeting mining companies (primary), mineral exploration firms, and oil and gas operators. Pricing is quote-based and project-scoped, with services contracted individually or as fully integrated packages and delivered on-site via direct enterprise sales. The engagement with Jaguar Mining Inc. as a Tier 1 drilling contractor for a 227,200-meter, US$43 million, 5-year exploration program in the Iron Quadrangle — alongside co-contractor Major Drilling Group International Inc. — exemplifies the multi-year, contract-driven revenue structure typical of large mining clients.
