Sammendrag

The Øvre Gorrzejohka gold-mining camp is situated at the northern side of the confluence between Gorrzejohka and Ai'bmejohka (Ravutjåkka; spelled Ravkjokka by Bjørlykke 1966). Gold has probably been panned from the top layer of reworked till in the river terrace 3 m above the river.

Abstrakt:

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.

Sammendrag

Gold digging has occurred on the southern side of the Hæs'tajohka river (called Stirkojokka in Bjørlykke, 1966) over a distance of about 800 m from its confluence with Gorrzejohka river. The top layer of the low terraces along the river has been worked for alluvial gold.
