The principal owner of the company is Maria Leticia Valadares de Vansconcelos, and Lincar stresses rigorous quality control and punctual delivery. Its quarries stretch across an area of nearly 300 acres, and they contain gray, multicolor, black, green and purple slate quarries. In fact, the firm opened a green/purple quarry specifically to attend to the American market, because it had some difficulties purchasing green slate blocks from other quarries.
The company's largest quarry is for gray and multicolor slate. This site, which is in Papagaio, produces 160 cubic meters of stone per day, and it employs 40 workers. The black quarry is located in Martinho Campos, Minas Gerais, and it producess a total of 120 cubic meters of stone per day, with 35 people working at the site. The third quarry site, for green and purple slate is located in Felixlândia, Minas Gerais. This quarry has 25 workers, and it yields 65 cubic meters of stone per day.
