Noricum Gold Limited ('Noricum Gold' or 'the Company')
Significant Multi-Element Results Received from Rotgülden Regional Sampling
Noricum Gold Limited, the Austrian focussed gold exploration and development company, is pleased to announce further multi-element results from regional reconnaissance fieldwork. This work was undertaken at three targets along both the northern and southern extension of the 100% owned, 51 sq km Rotgülden gold and precious metal licence in Austria ('Rotgülden').
Overview
·; Highly encouraging results from a variety of mineralising styles continue to highlight the regional scale and high grade potential of the Rotgülden licence
o Seeleiten - surface sampling has returned assays with bonanza grades up to 28g/t of gold and silver up to 147.3g/t
o Sticklerhütte - several serpentinite bodies have been located that have base metal anomalism up to 1.03% copper and 0.31% nickel
o Eisenkopf ('Iron Head') - evidence of both magnetite and haematite found in scree with iron assays between 57% and 59% iron
·; Field work in 2012 will focus on finding the source of these samples and mapping its extent
·; Further assay results expected in the near term from 1,800m drill programme at Rotgülden mine and downhole electromagnetic work nearing completion
Noricum Gold Managing Director Greg Kuenzel said, "We continue to delineate new exciting bonanza and multi-element targets along the 8km of prospective strike within the Rotgülden tenure. With our successful 1,800m drilling campaign at the previously producing Rotgülden mine complete and the final results expected in the near term, we continue to conduct reconnaissance outside of this historical centre to strengthen our understanding of the prolific mineralisation apparent in the licence area and we are continually encouraged by the results. The presence of iron, nickel and copper credits, along with high grade gold and silver, is particularly of note. These targets, along with our highly prospective Altenberg and Schurfspitze prospects, will be tested further during the 2012 field season."
Detailed Information
Regional fieldwork on the Rotgülden licence has centred on the larger southern extension of mineralisation from the previously producing Rotgülden mine. As the drilling was being conducted at Rotgülden the field crews were able to conduct additional reconnaissance exploration on the northern strike extension of the mineralisation. Further encouraging results were achieved from a variety of mineralising styles that require follow-up work next field season.

Seeleiten
The Seeleiten occurrence is thought to be the northern continuation of the Rotgülden deposit. It is located approximately 500m north northwest of the Rotgülden mine on the opposite side of Rotgülden Valley. Historical mining activity has been detailed in old literature and an adit is clearly visible from the valley floor. The mineralisation is located in very steep terrain and access to the adit was not possible when field work was being conducted. Below the adit, samples consisting of massive arsenopyrite with chlorite (similar to Rotgülden) were found, also sampled was a limonitic vein. In contrast to the Rotgülden mine, the host rock of the ore bearing samples was black schist. Certain secondary yellow and green minerals were noted during the sampling.
The following table details the chemical assays from the four samples taken in the area. The results highlight the sizeable regional potential of this mineralisation with results to circa 28g/t of gold ('Au') and 147.5g/t silver ('Ag'). SEE 3 also had 0.51% copper ('Cu').
SampleID | Au_ppm | Ag_ppm |
SEE 1 | 0.74 | 1.4 |
SEE 2 | 8.88 | 30.7 |
SEE 3 | 28 | 147.5 |
SEE 4 | 3.75 | 27.7 |
Sticklerhütte
The north westernmost part of the Mur Valley consists of an Upper Mesozoic ocean floor succession with greenschist hosting several serpentinite bodies. These serpentinite bodies are hosting a disseminated sulphide and oxide mineralisation which was mined at several places. Primary targets of mining activity were copper, nickel ('Ni') and cobalt ('Co').
Two locations, Göll Alm and Sticklerhütte, were visited. Samples from dumps of both places consisted of massive sulphides and a disseminated magnetite/sulphide mineralisation. The strike extension of the serpentinite bodies is up to several kilometres and as such provides an excellent exploration target.
Four samples were taken from Göll Alm and another four samples from Sticklerhütte. The results are tabled below:
SampleID | Co_ppm | Cr_ppm | Cu_ppm | Ni_ppm |
STIC 1 | 269 | 2740 | 2491 | 1097 |
STIC 2 | 2176 | 565 | 10328 | 3122 |
STIC 3 | 255 | 238 | 3333 | 464 |
STIC 4 | 840 | 217 | 9842 | 1305 |
STIC 5 | 3186 | 774 | 3177 | 3179 |
STIC 6 | 1084 | 2247 | 6536 | 1063 |
STIC 7 | 247 | 2075 | 2660 | 1326 |
Eisenkopf ('Iron Head')
Eisenkopf or Iron Head is mentioned in academic literature as an iron ore occurrence. It is located around 500m north of the Altenberg target where bonanza grades of up to 86.4 g/t Au have been returned from sampling (ie between Altenberg and Rotgulden). Mining activity was reported from Ochsenkar, which is located north of Iron Head. There are several adits but because of wet weather and steep terrain they were not accessible at the time of field work. Samples from scree material showed iron ore consisting of massive magnetite and massive hematite. Extension of the mineralisation is still unknown yet could be easily traced by an aerial survey.
The results for the magnetite samples (IH 1 and IH 2) show very high grades of iron ('Fe') for a magnetite sample. The mineralisation was coarse grained and it is likely that any magnetic separation would produce and even higher grade concentrate with fewer impurities. The third sample, IH 3, was massive haematite.

Field work during 2012 will focus on finding the source of these samples and mapping its extent.
