Minrom

What Minrom does

Minrom is a privately held, founder-owned mining geology consulting firm headquartered in Cape Town, South Africa, founded in 2009 by CEO Oscar van Antwerpen. The company provides professional geological services across the full mining project lifecycle, organized into six practice areas: Strategy, Exploration, Resource Modelling & GIS, Mining Geology, Hydrogeology, and Geology Training. Deliverables include mineral resource estimates, block models, and technical reports compliant with JORC, NI 43-101, and SAMREC codes. The technical stack is built on 3D geological modelling platforms (Micromine, Leapfrog), GIS spatial analysis, geostatistics, and Minrom's own StereoCore core-logging software, which exports validated drill-hole datasets into those third-party modellers.

Minrom serves three primary client segments: junior explorers and prospecting companies, established mining companies, and mining investors/financiers requiring independent technical reviews and project valuations. Projects span commodities including gold, copper, PGMs, manganese, graphite, and other critical minerals, with operating geography concentrated in Southern, Central, and East Africa plus selected assignments in Australia. The firm is small (11-50 employees) and services are delivered by SACNASP-registered Professional Natural Scientists, several of whom serve as Competent Persons under JORC.

Revenue is generated primarily through fee-for-service consulting engagements, supplemented by three product lines: StereoCore software (pay-as-you-use licensing), a physical Minrom Field Equipment Kit, and the Box of Rocks educational toolkit. Distribution is direct via a discovery-call booking model, with the website localized into 7 languages and supported by content marketing, social media, and a newsletter. No external funding, acquisitions, or revenue figures are disclosed.
