DeepTech • AgTech • MineralTech

A DeepTech platform turning mineral science into agricultural and industrial products.

GAIA LITHOS combines geology, mineral processing and applied validation to develop K-Mg mineral inputs, industrial minerals, strategic co-products and climate-related R&D from a single syenitic system.

Technology-led product development. Mineral assets as the foundation. Built for global investors and partners.

OpenVC Positioning

A deeptech startup built on mineral assets and applied validation

The company narrative centers on technology, product development and scalable applications. The mineral-rights base is the enabling infrastructure that supports a broader innovation platform.

Technology Thesis

Why this behaves like a startup platform

GAIA is not framed as a traditional mine developer first. It is framed as a technology-driven venture that transforms a geological system into validated product opportunities.

DeepTech

Applied mineral science

A technical stack integrating geology, mineral processing and characterization to create defensible product knowledge.

AgTech

Agricultural mineral inputs

Evaluation of K-Mg-bearing natural minerals for soil remineralization, field applications and climate-adjacent agricultural use cases.

MineralTech

Multi-product processing pathways

One mineral system, multiple product pathways: industrial minerals, K-Mg products and strategic co-product potential.

24-month roadmapThe staged de-risking process designed to build technical evidence before scaling decisions.

Technical Foundation

The mineral system behind the platform

The startup thesis is supported by two syenitic bodies — Caboclo and Nova Olinda — whose historical mineralogy and geochemistry motivate the current development program.

Caboclo Syenite

Historical mineralogy

Quartz ~11%
K-feldspar ~50%
Biotite ~23–30%

Nova Olinda Syenite

Historical mineralogy

Quartz ~5–7%
K-feldspar ~43–48%
Biotite ~25–35%

Historical Whole-Rock Geochemistry

SiO₂~56–63%

K₂O~6.2–7.6%

MgO~3.7–5.8%

P₂O₅~0.5–1.0%

ΣREE~270–394 ppm

These historical values do not constitute a mineral resource or reserve estimate. Historical geological data are being independently validated as part of the current development program. Source: previous geological studies, including Perpétuo (2017), subject to independent validation by GAIA LITHOS.

De-Risking Roadmap

24 months to build the evidence base

The roadmap converts geological potential into investable technical evidence through characterization, processing, validation, exploration and climate-related R&D.

01

Characterization

Mineralogy, geochemistry, XRD, QEMSCAN/MLA and representative sampling.

02

Mineral Processing

Crushing, HPGR, magnetic separation, gravity concentration, grinding and mass balance.

03

Product Validation

Industrial-mineral qualification, K-Mg characterization, agronomy and heavy-mineral studies.

04

Exploration

Mapping, sampling, bulk samples and drilling where technically justified.

05

Climate & MRV R&D

Enhanced rock weathering research, carbon accounting and MRV development.

AgTech + Climate R&D

Sustainable applications are a research track, not a marketing claim

GAIA is evaluating how naturally occurring K-Mg-bearing minerals may support soil remineralization and enhanced rock weathering, with experimental validation and MRV built into the roadmap.

Soil remineralization

Research into naturally occurring K-Mg-bearing minerals for agricultural applications in sandy and low-fertility environments.

Dry processing

Development concept oriented toward reducing water intensity and avoiding conventional tailings-dam dependency where technically feasible.

Enhanced rock weathering

Geochemical testing, carbon accounting and MRV research. Carbon-removal performance has not yet been validated.
