Balances of mineral resources in analogous format are available in the State Geological Fund starting from 1959. In the Register of Deposits of the Unified Environmental Information System, the stock balance of construction raw materials, peat, sapropel and healing sludge for the resources exploited in the specific year has been available for the period of time starting with 2001.

N/A

Stock balance of previous years of geological documentation issued by the National Geological Service, State Agency “Latvian Environment, Geology and Meteorology Agency” and State Environmental Service (hereinafter – SES), reports on the extraction of mineral resources submitted by SES regional environmental boards, LEGMA's databases “Deposits of construction raw materials”, “Peat deposits” and “Sapropel and sludge” have been used to produce the balance sheet.

The balance sheets summarize the data on active stocks in the deposits used in the respective year. Until 2018 (inclusive) balances of mineral resources, construction raw materials, peat, sapropel and healing sludge deposits are provided for the deposit as a whole.

Starting from 2019, balance sheet is being produced by mining sites.

Stock balance of mineral resources (construction raw materials, peat, sapropel and healing sludge) has been prepared by the state Ltd “Latvian Environment, Geology and Meteorology Centre” in accordance with Article 5 of the Law of the Republic of Latvia “On Subterranean Depths”.
