Abstract
The river terraces along Bavtajohka river have been the sites for several attempts to exploit gold by panning and use of sluices (Bjørlykke, 1966). The terrace surface that is situated 5-6 m over the present water level in Bavtajohka river, has been worked for a distance of 100 m along the western side of the river about 1 km above the confluence with Karasjohka river. The terrace consists of an upper 1,2-1,5 m thick unit of sand and gravel with large boulders, overlying clay-rich blocky till. Gold is mainly concentrated along the interface between reworked and untisturbed till.

Abstract:
The first find of alluvial gold in Finnmarken was made by inspector (bergmester) Tellef Dahll in 1866 in sand from a small river named Nitusjokka near Karasjok. During the following 5 years gold deposits were found in all the rivers of the Tana river systm and the Alta and Reisa rivers. Gold has been found in small amount in all kinds of sand- and gravel deposits and also in the unwashed moraine deposits. The gold fields which have been subject to production or prospection work are situated at the upper parts of the rivers. The occurrences of alluvial gold in Finnmark may be classified in The following way: 1. Preglacial accumulations undisturbed by ice erosion during the ice age. 2: Preglacial accumulations disturbed and redeposited in moraines and fluvioglacial deposits. 3. Accumulations in postglacial river beds. The gold in these deposits seems chiefly to have been washed out from the moraines. Mineralogical analyses of the mineral composition of the gold-bearing sand and gravel have been carried out. The minerals of the gold-bearing deposits may be divided in two groups: 1. Minerals belonging to the surrounding solid rock. 2. Minerals which do not seem to belong to the solid rock in the neighbourhood of the deposits.

Abstract
Immediately south of the confluence with Gæs'sajohka river occur some old pits worked in the terrace 7-8 m above the present water level. As in the main Bavtajohka gold camp the gold probably occurs at the interface between indisturbed and reworked till. No attempts have been made to pan gold in the Gæssejohka river (Bjørlykke 1966).
