About Us

OLIBUL Investments Limited is a proudly Zambian, citizen-owned company with over a decade of operations in sand mining, limestone quarrying, industrial minerals, and cross-border bulk haulage freight across the North-Western Province and the regional SADC corridor.

• Laboratory & QA System validation — Asses the specified plant laboratory (spectrometry, metallography, hardness) and design an ISO 9001-aligned quality management system with batch traceability, ready for deployment.
• EPC / Technology-Partner Liaison — Act as the owner's technical counterpart through installation, commissioning, and acceptance testing.
• Customer engagement & Co-Creation Support — Lead plant trials and wear-rate benchmarking with mine customers in Zambia and the DR Congo, feeding results back into product development.
