Noricum Gold Limited ('Noricum Gold' or 'the Company')

Aerial Geophysics Programme to Accelerate Rotgülden Project, Austria

 

Noricum Gold Limited, the Austrian focussed gold exploration and development company, announces that, in line with its 2012 exploration programme to advance the 51 sq km Rotgülden gold and precious metals project area in south central Austria, it has appointed Geotech Airborne Limited ('Geotech') to undertake an extensive aerial geophysical programme at the licence area.

 

Noricum Gold Managing Director Greg Kuenzel said, "The Company is very excited about the prospectivity of an 8km mineralised strike running through the Rotgülden licence. Having proven the effectiveness of using EM to highlight the massive sulphide gold mineralisation present at the previously producing mine target, we look forward to commencing this wider aerial geophysical campaign next month. We are confident that this will pinpoint targets for our maiden drilling campaign at Altenberg located on the southern extension, where bonanza gold and silver results were received from work last year. We also hope to highlight new mineralised areas and look forward to keeping shareholders abreast of the results over the coming months."

 

Full Details

 

Geotech, under the supervision of Southern Geoscience Consultants, will undertake a survey, expected to commence in May 2012, at the Rotgülden project, to accelerate Noricum's exploration efforts and knowledge of an 8km strike line running through the licence area, which is highly prospective for high grade gold, silver and copper mineralisation (see Table 1 below). Geotech will perform a helicopter-borne geophysical survey over approximately 599 line-kilometres of VTEM (Versatile Time-Domain Electromagnetic) and magnetics over the Rotgülden tenure. The survey area is 9km by 3km and is likely to be able to see to a depth of more than 200 metres.

Figure 1 - Example of helicopter-borne VTEM (Please see PDF at the top of the page.)

 

The first year of exploration, which included a down hole electromagnetic ('EM') survey at the previously producing Rotgülden underground mine, determined that EM and magnetic techniques work in particular situations at a variety of prospects. The mine hosts a massive sulphide ore body containing high grade gold, silver and copper mineralisation. It is also likely that prospects with an analogous style of mineralisation (Shurfspitze, Seeleiten and Altenberg) would also be conducive to this type of investigation. Additionally, the mineralisation at the Rotgülden underground mine has a significant component of pyrrhotite, which is also amenable to investigation by magnetic methods.

 

It is likely that the remaining prospects have either enough sulphides to be visible to EM methods, or pyrrhotite that would be visible to magnetic methods (see Table 1 below).

 

It is also expected that the magnetic survey will provide additional significant information about the geology of the survey area. It is hoped that such information will further improve the Company's already detailed knowledge of the area. The survey area is shown in Figure 2.

Drilling Programmes

 

It is intended that this geophysical programme will not only identify additional areas of mineralisation, but also assist in optimising the drill programme currently being planned for Altenberg and scheduled to commence later this year. The Directors believe that the geophysical survey is a cost effective tool, which will enable the Company to quickly define targets from a large land holding in a relatively short period of time.

 

The Company also expects that extensions to the Rotgülden mineralisation are likely to be uncovered by this survey, which will assist in the planning of further resource drilling.
