| The Mayber’s Fortune occurrence is located 7.5 kilometres south west of Terrace, 4 kilometres west of Lakelse lake on the Lakelse River. In 1966–1967, a mineral exploration program of combined photogeological and field geological analysis and photogeology was conducted in the area by Cree Lake Mining Company Limited.
Several isolated blocks of massive, Permian (?) limestone out- crop just west of Lakelse Lake, 14 kilometres south-southwest of Terrace. The limestone is contained in a sequence of thin bedded quartzite, graphitic argillite and argillaceous limestone that is intruded by Jurassic to Tertiary aged granite and diorite of the Coast Plutonic Complex. The limestone is usually white, but sometimes displays a green or bluish grey colour. It is extensively recrystalized and coarse grained in texture. Epidote-garnet skarn zones with minor magnetite and sulphides are locally developed in the limestone.
One 30 metre thick block of limestone extends for 108 metres northeast from the Lakelse River, crossing the Canadian National Railway at the 10 mile point. The bed strikes 040 degrees and dips 25 degrees southeast. The block is estimated to contain at least 454,000 tonnes of limestone (K.P. Bottoms, 1967, pp. 3, 10). A representative sample from this block assayed 96.3 percent calcium carbonate and 1.59 percent magnesium carbonate (K.P. Bottoms 1967, p. 10). At least two other deposits of relatively pure limestone outcrop to the southeast.
