Zimlabs

What Zimlabs does

Zimlabs (legal entity: GNK Laboratories t/a ZIMLABS) is a privately-held, ISO/IEC 17025:2005 accredited independent laboratory testing company headquartered in Ruwa, Harare, Zimbabwe. Founded in August 2002 as a partnership by Grarison Bake and Kizito Vaushe, the business was incorporated in 2005 and now operates four branches (Ruwa HQ, Masasa, Kadoma, Bulawayo). The company provides accredited analytical services across four vertical-aligned product lines: mining and geochemical analysis (covering PGM fire assays, lithium and rare earth elements, iron ore, base metals, coal, and metallurgical testwork), water and environmental analysis (over 36 chemical parameters including heavy metals, plus microbiological testing of drinking water, wastewater, effluents, surface and groundwater), agricultural laboratory services (soil, plant tissue, irrigation water, stockfeeds and fertilizer analysis), and hospitality and food industry testing (chemical and microbiological food safety verification).

Underlying technology is conventional accredited wet-lab instrumentation, complemented by a barcode-based Chain of Custody sample management system that logs unique IDs into a laboratory information management system (LIMS) for end-to-end traceability. A separate Onsite Services capability deploys mobile sample preparation facilities and full-service mine control labs directly to exploration projects and mine sites. Revenue is generated on a usage-based, quote-per-sample model across all four verticals, with enterprise customers submitting samples either at branch locations or through onsite engagements; mining companies, municipalities, government agencies, agricultural operations, and hospitality groups form the core customer segments.

Service delivery runs through an enterprise field-sales motion with direct relationships — the company cites Great Dyke Investments (PGM exploration, official assay partner since 2015), Prospect Lithium Zimbabwe (Arcadia Lithium, 2016-2019), Zimplats, Unki, Blanket Mine, Metallon, Murowa Diamonds, SeedCo, Lafarge Cement, Meikles Hotel, Victoria Falls Hotel, UNICEF, the British Embassy (2021 three-year water analysis contract), FAO (2020 soil analysis tender), municipalities, and Carlsberg Malawi among its enterprise book. The business is founder-controlled with no disclosed external investment and is described in its own material as Zimbabwe's leading laboratory testing company.
