Dragon Mining Oy is a Finnish mining company that conducts ore exploration around its mines. Dragon Mining Oy is owned by the Australian Dragon Mining Ltd, which is listed on the Hong Kong stock exchange. In 2024, the company have an operating gold mine in Jokisivu Huittinen, where the ore is mined underground. The production of Kaapelinkulma mine in Valkeakoski ended in April 2021 and the production of the Orivesi mine ended in June 2019. In these mines the closure processes are ongoing. The ore mined from the Jokisivu mine is processed at the Vammala Plant in Sastamala. The Vammala Plant is a conventional flotation facility that produces gold concentrate and a lesser amount of gravity gold. The company’s main product is gold concentrate.
The answers presented in the social responsibility report concern the Jokisivu, Kaapelinkulma and Orivesi mines and the Vammala Plant.

According to the company’s own assessment, its operations partially have an impact on land use when the operational areas are away from other uses.
The finished operation of the Orivesi mine had effects on the two lakes below. The state and quality of the lakes are monitored regularly. In the trial fishery carried out in 2024, the perch population in lake Ala-Jalkajärvi has increased significantly since 2021, and the trial fishery catch was so abundant that the net unit catch was even more than twice the unit catch in the next lake Peräjärvi. The size distribution of the perch catch in Ala-Jalkajärvi was diverse, presumably representing many age groups. The change in the perch population is an indication that conditions have become more favorable for the fishery after the metal concentrations in the water have clearly decreased.
From lake Ala-Jalkajärvi, the waters flow through Horhanpuro to Lake Peräjärvi. The strong stratification of lake Peräjärvi has narrowed the area with sufficient oxygen and viability for fish, and this time too, the four deepest nets were completely devoid of fish. The biggest change in the 2024 test fishing results of Lake Peräjärvi was the decrease in roach compared to the three previous monitoring sessions. The number of perch catches has remained more or less the same. According to water monitoring, the stratification of Lake Peräjärvi, which is caused by sulfate concentrations, has been partially break down in both 2023 and 2024. This development trend will significantly change the conditions for fish and other organisms in a positive direction.
The cessation of the mine discharge waters and recent changes in the water quality and metal concentrations of Lake Peräjärvi have probably contributed to the fact that the signal crayfish has finally spread from the Peräjoki River to Lake Peräjärvi. Experimental crayfish collections in Lake Peräjärvi have been carried out since 2003, and the two spotted crayfishes from there in 2024 were the first in the observation history.
