Vancouver A newly completed $470,000 program by True North Gems (TGX-V) has identified 8 new target areas on the True Blue emerald property in the Yukon’s Finlayson Lake district.
The program resulted in 50 individual beryl showings. The green variety of beryl is known as emerald while other varieties of beryl gemstones are named based on their colour.
The occurrences cover a 500-sq-metre along a horseshoe-shaped valley head. The beryl crystals, which are from 1-to-2.5 cm is size, range in colour from pale blue to sapphire blue and pale green.
"We are particularly encouraged by the discovery of the deep blue-colour of the beryl," says company president, Bernie Gaboury. "This is an extremely rare colour and there is only one other known deposit of this colour of beryl in the world."
The mineralization is marked by a Cretaceous granite body, which intrudes chlorite schist and, along with pegmatite and aplite dykes, has deposited emerald and tourmaline mineralization with associated carbonate, sericite and phlogopite alteration of the host rock. The mafic schists occur within the Fyre Lake metavolcanic unit that crops out over a large part of the Finlayson district. The granitic intrusions are enriched in beryllium and tungsten. The mineralized veins form a complex structural network.
The junior is now completing a $60,000 follow-up program comprising more geochemcial sampling.
