He sold the stones, which are blue or deep purple and found only in Tanzania, to the government for 7.7 billion tannins ($ 3.3 million).
After receiving a check during a ceremony attended by senior Tanzanian government officials last week, Laizer said he would spend the money on his community.
“The money I’ve made from selling my tanzanite, I plan to use it to build a school to support my community and a mall to support my family,” he told a show on state television network TBC.
Tanzanian President John Magufuli congratulated the miner and said the achievement showed that “Tanzania is a rich country. This is really to the benefit of artisanal miners. “
Biteko said smaller miners should not be discouraged by the fact that they do not have modern mining technologies.
“It simply came to our notice then [the] the largest tanzanite in the history of tanzanite mining in our country, so the president had to order us to buy them and keep them [them] until later, when we decide what we want to do with them, “Beteko told the show.
In recent years, Tanzania has made changes to its laws to increase its share of the benefits of discovering and selling resources.
As a result, foreign mining companies – including gold and graphite mining companies – are set to give the government 16% of their equity for free, as required by law.
Undersecretary of Finance and Planning Ashatu Kijaji said the discovery of the stone leads to a new era of operations for local artisanal miners to take advantage of the country’s resources.
