Clay Lake Gold Target | Conroy Gold and Natural Resources

The Clay Lake gold target extends for 2 km by 1 km, (c.140 ha / 350 acres) and lies at the north-eastern end of the 30 mile gold trend which Conroy Gold has discovered. This target was named after the Clay Lake Nugget; a 30.05g nugget with a gold content of 28g. The nugget was found in the mid 1980’s and is now displayed in the Ulster Museum in Belfast.

Shale - Wikipedia

Shales are typically composed of clay minerals and quartz grain, and are typically gray. Addition of variable amounts of minor constituents alters the color of the rock. Black shale results from the presence of greater than one percent carbonaceous material and indicates a reducing environment. Black shale can also be referred to as black metal.

Shale | Minerals Education Coalition

Other minerals present in shale are quartz, mica, pyrite, and organic matter. Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor. Geologists estimate that shale represents almost ¾ of the sedimentary rock on the Earth’s crust.
