LOC ENVEL TUNGSTEN PROJECT

The Loc Envel licence covers an area of 336 square kilometres in northwest Brittany over a region believed to have good potential for high grade tungsten-copper deposits.

Work by Variscan has identified several potentially commercial styles of deposits within the licence closely associated with several small trondhjemite intrusives -

  • High grade scheelite + (wolframite) + chalcopyrite exo-skarns with semi massive to massive pyrrhotite mineralization similar to the Salau (Pyrénées, France), Pine Creek (California, USA) and Cantung (Yukon, Canada) deposits;
  • Substantial quartz + scheelite + wolframite + molybdenite vein stockwork systems of the Hemerdon Ball (South Devon, UK) type; and
  • Sheeted vein quartz + scheelite + wolframite + (cassiterite) + base metal sulphides in the apices leucogranite and granitic porphyry intrusive stocks.

The most significant deposit defined to date is Coat-an-Noz where scheelite-bearing skarns (type A mineralisation) have been defined over a two kilometre strike length in exploration carried out from 1960 to 1977 by the BRGM and SNEAP (Société National Elf Aquitaine Petroliers).

Although data from this exploration is yet to be accessed and evaluated, diamond drilling from the Coat-an-Noz prospect is reported to have generated high grade tungsten (+copper) intercepts within the laterally continuous skarn system and enabled SNEAP to calculate a non-JORC resource. This represents a priority target for Variscan.

Further evidence of the prospectivity of the area is provided at the Toul Pors prospect where exploration work including trenching and short  100 metre) core holes has identified a large stockwork of quartz-tungsten-molybdenite bearing veins hosted by amphibolites within the cupola of the Toul Pors granite.
