Although these syenites, particularly the 'dark' varieties,
are similar to the famous laurvikites from Norway, no markets

Denison Mines Limited in 1960 attempted to determine the
nepheline potential of the feldspathoidal syenites from two areas
located south of Highway 17 and west of Red Sucker Cove. However,.
nepheline separation proved hard to achieve, and iron content of
the concentrate was too high, so the project was abandoned.
