| The Godejord deposit comprises massive to banded and disseminated sulphides in a variably tuffaceous, calcareous and cherty host. The ore level is 5 to 10 m thick and occurs in the upper part of a thick sequence dominated by tuffaceous or epiclastic sediments with interlayered felsic effusives. The succession contains abundant exhalite formations, some of which are rich in fine-grained spessartine. The ore lies stratigraphically on top of a 10 m thick layer of magnetite-bearing chert with local Mn enrichments, and is separated from an overlying basaltic unit by a thin zone of calcareous sediments similar to those below the orebody. The richer parts of the laterally extensive Godejord zone have been estimated to contain about 0.1 Mt with 0.8 % Cu, 6.9 % Zn, 0.2 % Pb, 20 g/t Ag and 0.8 g/t Au calculated at a cut-off of 2 % Cu equivalents. The actual massive and semimassive ore, however, is considerably richer and is known for its high contents of silver and gold and its unusual mineralogy, including Fe-poor sphalerite, fahlore, Cu-Ag±Te sulphides, Cu-Sn sulphides and native gold. Parts of the ore zone also contain notable amounts of barite. Godejord have a historical non NI 43-101 compliant resource of 250 kt million tons @ 0.6 % Cu, 4.2 % Zn, 15 ppm Ag and 0.4 ppm Au at a 1 % 1996 Cu-equivalent cut-off (METPRO 2013). |
