| A 5m long E-ward adit in the mineralization right down at the sea shore has been assessed. In the adit, the mineralization has a thickness of 0.7m, wedging out and disappearing in the slope above the adit, being untraceable towards E. The medium grained quartz-biotite host rock contains semi-massive pyrrhotite with some pyrite, chalcopyrite, sphalerite, magnetite, and minor molybdenite (samples 01-05). The surrounding rock is monzonite (sample 06). |

| Rapport over Lonkanfjord kisfelt på Hinnøya. |

| Abstract: | |
| Forf. beskriver beliggenhet og geologi. Forekomsten ligger i augitt- syenitt og består hovedsaklig av magnetkis, svovelkis, kobberkis, molybdenglans og magnetitt. To forekomster blir beskrevet. Ved Grundvika er en gang av massiv kis (1,5 m) funnet i en stoll. Den andre sona ligger i Rindvassheia der det også er gjort en del påhugg. Malmen er fattig. Forf. konkluderer at feltet bør undersøkes nærmere med stolldrift, røskning og geofysiske arbeider. |

| Abstract: | |
| Rapporten etter befaring. Forf. viser til to hovedtyper av malm. 1. Små ganger av massiv kis 2. Større partier av fattige impregnasjonsmalm. Forekomstene blir bedømt som økonomisk uintressante. Vedlagt er resultater fra en del kjemiske analyser. Vedlagt er også et brev fra S. Foyn til Utbyggingsfondet for Nord-Norge der det blir anbefalt å ikke bruke mer penger på undersøkelse av forekomster. |
