# Minrom

> South African mining-geology consultancy specialising in lithium, copper, graphite, rare earth elements, manganese, gold, chrome, platinum, nickel, uranium, iron ore, coal, diamonds, tungsten, lead, zinc, and industrial minerals exploration, resource modelling (JORC / SAMREC), mining geology, and hydrogeology across Sub-Saharan Africa.

## About

Minrom is a boutique mineral resource consultancy based in South Africa, delivering independent geological advisory to junior explorers, producers, investors, and government agencies across the African continent. The firm provides end-to-end coverage from early-stage prospecting through resource estimation, mine planning, and compliance reporting under JORC and SAMREC codes.

Typical engagements include critical-minerals and mining exploration programmes covering lithium, copper, graphite, rare earth elements, manganese, chrome, gold, platinum, nickel, uranium, iron ore, coal, diamonds, tungsten, lead, zinc, and industrial minerals. Services include geological and resource modelling, hydrogeology for mine dewatering and water supply, independent due-diligence reviews, and technical training for in-country geology teams.

Minrom is owner-led by Oscar van Antwerpen and staffed by working geologists with field experience across Sub-Saharan Africa. The firm is small by design — senior geologist engagement on every project, and direct communication with principals.
