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.

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.
Knowledge Transfer & Handover — Codify SOPs, mentor the in-house technical team, and execute a structured handover to the permanent Head of Metallurgical and Metals.
