The Ojamaa mine is an oil shale mine in Ida-Virumaa with a production center in Võrnu village. The Ojamaa mine is located in the central part of the Estonian oil shale deposit, to the north of it is the closed Aidu quarry and the Kohtla mine.
The mine is managed by VKG Kaevandused OÜ, a subsidiary of Viru Keemia Grupp (VKG). The mine is located 12.5 km from VKG shale oil production plants in Kohtla-Järve. They are connected by a ground covered conveyor.
Aidu’s quarry is a surface mine that started operating in 1974 and closed in 2012. The quarry is located in Aidu village, Ida-Viru county, Lüganuse municipality.
In August 2013, a 2.3 km long, 162 m wide and 3.5 m deep rowing canal was completed there. In addition to the water sports center, a wind park, shooting range, mine waste recycling area and various recreational opportunities are planned for the former oil shale quarry area. Over the years, more than 4 million trees have been planted on the former mining area.
