Erris Resources obtains gold exploration permit for project in Sweden

European focused mineral exploration company with a portfolio of zinc prospects in Ireland and gold projects in Sweden, Erris Resources plc, has been granted a gold exploration permit for its Enåsen no.5 (the Enåsen Project), in central Sweden. 

CEO of Erris Resources, Merlin Marr-Johnson, said: "We are delighted to have been awarded the Enåsen exploration licence in central Sweden, which surrounds the historic Enåsen open pit gold mine.  Discovered in the 1980s, the Enåsen mine is one of the few gold-only mines in the country - typically gold from Sweden is produced as a byproduct from the mining of massive sulfide deposits. The Enåsen Project encompasses the area surrounding the mine and is largely underexplored, covering an area we believe is a prospective geological setting.  The company is now starting the first phase reconnaissance programme of mapping and sampling at the Enåsen Project.”


"The addition of the Enåsen Project to our existing portfolio of projects is in line with our stated objective of identifying low-cost opportunities with the potential to create shareholder value.  Work is ramping up across this portfolio; we are currently drilling the Abbeytown zinc project in Ireland and working on a portfolio of projects in Sweden funded by Centerra Gold.  I look forward to updating shareholders on progress in due course."


The 54.9 km2 Enåsen licence no. 5 is for an area situated approximately 370 km north of Stockholm and 50 km west of Sundsvall, in central Sweden.


Geological Survey of Sweden (SGU) reports that the geophysical data indicates the host geology of the area to comprise a belt of volcanics trending northwest on a sub-parallel major gravity break and terrane boundary. The surrounding geology is composed of sediments and granitoids.


The Enåsen deposit is reported to be a metamorphosed high-sulfidation deposit (Hallberg, 1994). The mineralisation is characterised by disseminated chalcopyrite and gold in a topaz-bearing quartz-sillimanite gneiss hosted by quartz-feldspar and quartz-mica gneisses. Open pit mining at Enåsen started in 1984, followed by underground mining in 1989. Total production in open pit and underground workings until the closure of the mine in 1991 was 1.7 million t at a grade of 3 g/t gold.  A 1 km exploration permit buffer exists around the granted exploitation permit.


The licence is held wholly by Erris Resources and is not part of the joint venture that Erris Resources has in the Skellefteå mining district with Centerra Gold KB Inc, a wholly owned subsidiary of Centerra Gold, Inc.


Erris Resources has integrated historic data sets and carried out a new interpretation of the regional aeromagnetic data across central and southern Sweden, the results of which were a key driver for acquiring the new licence areas. A further desktop structural interpretation is underway and will be supplemented by new multi-element data from reconnaissance mapping and sampling in the forthcoming field season.
