In Framfjord mining took place at the following sites: Johilleren, Kalveskår-mine, Dale-mines, Katlaberget, Gammelgruven, Ørneredet, Skredhamrane and Klev. The old mines are regarded as empty, or impossible to mine. In the literature the names Hatleberg and Hellenes occur (e.g. Helland 1893). These names represent the northern continuation of the soapstone at Dale. At the Storegjelet deposit a tonnage of 40000 tonnes is described. Difficult access is the primary reason why the deposit has not been mined. According to report BA 7473 there is also a deposit at Kleivane, but the access is difficult also at this deposit. A great number of old reports exist from the mining and prospecting activity in Framfjord, and the reader is referred to these for further reading; reports with anonymous authors: BA 7474, BA 7473, BA 7471, BA 7472, BA 7470, BA 7475, as well as Ross (1962), and more recent reports by Bakke (1982), Torstensen (1981, 1982) and Sindre (1986). In addition some reports deal with processing: Sandvik (1984) and Ljøkjell (1988). From Karlsen and Nilsson 1999.

Talc deposits in Norway

Abstrakt:
Information about talc and soapstone deposits registered in NGU's different databases and various available literature have been collected and described in the present report. Around 400 deposits/occurrences are known, but the detail of the available information varies widely. By reading old field-books as well as old manuscripts, maps, etc. dating as far back as A.D.1758, quite a lot of data has been found. The result of the work shows that most described talc in Norway is of ultramafic origin and is associated with serpentinites. The most common mineral association is talc + breunnerite. Different talc-provinces can be defined from the registered and non-registered data, the most important being Nord-Gudbrandsdalen, Altermark and Stølsheimen. While Altermark and Stølsheimen have been investgated in some detail with respect to talc as an industrial mineral, the Nord-Gudbrandsdalen talc province has been investigated both for milling talc and for soapstone use as dimension stone. Deposits that are probably extensive, but have so far not been investigated in detail, include the Lesjehorrungane deposits in the Nord-Gudbrandsdalen region and the Raudfjellet deposit in Nord-Trøndelag. The fractionated metakomatiites (pale green talc-chlorite rocks) of the southern part of the Palaeo-proterozoic Karasjok Greenstone Belt in Finnmark, Northern Norway, possibly represents, by far, the largest accumulations of talc in Norway. These rocks are recently mapped, for the first time, but other critical information is, however, very scarce.
