Røros has an exciting newspaper history. In the years 1910 to 1913 and 1922 to 1927, the newspaper Waren Sardne was published in Røros. The title of the newspaper roughly translates into News of the mountains. The newspaper aimed to provide news of significance to the Sámi reindeer herders. The newspaper’s founder and editor was Daniel Mortenson [1860–1924]. In the first publication period, Søndre Trondhjem amts lappeforening (Sámi association of southern Trondheim county) was listed as the publisher of the newspaper. The chair of the Sámi association was Martin Jonassen [1874–1941].

The Sámi population was scattered, making it a challenge to stay in touch with Sámi people in other areas. A newspaper that could serve as an information interchange for Sámi people was therefore expedient. Freedom of association was prevalent the time – the idea that together, people could improve their situation. Printing ideas, thoughts and experiences in the newspaper would reach all the newspaper's readers.

In the early 1900s, the Sámi in the Røros area were under great pressure from several directions. Costly claims for damages were raised, based on alleged damage caused by reindeer grazing, which often ended up as disputes brought before the courts. The legislation was intended to safeguard agricultural interests – during a time in which the prevailing perception was that Sámi reindeer herding was detrimental to the other interests of society. In this situation, sharing information and experience with others in Saepmie (the Sámi cultural region) was important.

Another purpose of the newspaper was to promote Sámi demands to have the same rights as the rest of the population. There was a strong wish to inform the authorities about the challenges the Sámi people was facing. Consequently, most of what was printed in Waren Sardne, was in Norwegian.

The newspaper otherwise often included reindeer husbandry reports, for example the conditions during the calving period, the predator situation, the slaughter season and other relevant information. In addition, it ran shorter and longer news stories on various topics.

The newspaper was by no means a financial success. This probably contributed to the newspaper ceasing publication in 1913. Nor did the newspaper secure many subscribers during its second publication period.

Following Daniel Mortenson’s death in 1924, his son Lars Danielsen [1903–1982] took over editorial responsibility for the newspaper. He was the editor until the newspaper ceased publication in 1927.
