Mining, quarrying and building materials (licensed)
Kenya's building boom needs stone, ballast, sand and murram, and several counties have gold, gemstones and other minerals. These are physical, regulated businesses: done legally and safely they create good jobs; done illegally they destroy land and rivers and risk lives.
What these methods share
- Licences: minerals are governed by the Mining Act (2016) through the Ministry of Mining, with permits for artisanal and small-scale miners. Quarries and sand harvesting also need county permits and NEMA environmental approval.
- Safety: collapsing pits and quarries kill workers every year. Protective gear, safe slopes and no work in unstable pits are essential.
- Land and community: get the landowner's written agreement and engage the community.
- Rehabilitation: restore land after extraction (backfilling, trees).
722. Artisanal gold mining (licensed)
What it is: Small-scale gold mining by individuals or groups with an artisanal mining permit. How it works: Dig and process ore → sell gold to licensed dealers.
| Skills | Mining skills, safety awareness |

| Time to first income | Weeks to months |
How to start: Join or form a registered artisanal miners' group; get the county permit. Pros: Possible high value. Cons & risks: Dangerous pits; mercury poisoning. Scam warning: Sell only to licensed dealers; 'gold' sold to you outside the system is a common scam. Kenya notes: Migori, Kakamega, Siaya, Turkana and West Pokot have artisanal gold mining. Avoid mercury; safer methods exist.

| Time to first income | Months |
How to start: Learn gemology basics; partner with a licensed dealer before trading. Pros: High value. Cons & risks: Fraud and fake stones. Scam warning: Fake and glass 'gems' are common; test before paying. Kenya notes: Taita Taveta and parts of the Rift Valley are known for gemstones; dealing needs a licence.
