Nortec Minerals Re-sampling of GTK Core at Seinäjoki Reveals New High Grade Gold Zone- Expanded Drill Program Planned for Q2-2010
Vancouver, B.C., April 14, 2010: Nortec Minerals Corp. (TSX-V: NVT; FSE: WMQ; OTC PINK: NMNZF) ("Nortec" or the "Company"), is pleased to announce that excellent gold assay results have been returned from the select sampling of archive drill core within the Seinäjoki Gold Project. Assay values from the re-sampled core confirmed much of the historical data and included the discovery of a new high grade zone from 65 meters. Highlights of the re-sampling programme include intercept values of 5.75 g/t gold over 3 metres and 2.69 g/t gold over 4 metres at the Marttalanniemi Prospect (a zone not previously assayed by GTK geologists), and 1.03 g/t gold over 5 meters at the Ylijöki Prospect.
The relogging and re-sampling programme was carried out last month on drill core stored at the Geological Survey of Finland (“GTK”) core storage facility in Loppi, southern Finland. Select intervals of drill core were taken from 17 holes drilled by the GTK between 1978 and 1991 on both the Marttalanniemi and Ylijöki Prospects.
Nortec is awaiting the compiled validated drillhole assay dataset from the GTK (including the assay certificates), commissioned at the beginning of the year. The objective of the re-sampling programme was to confirm mineralisation from drillhole intervals, described in public domain GTK prospect reports. The best drill intercepts are tabled below and compared, where possible, to the historical GTK-reported drill intercepts:-
MARTTALANNIEMI and YLIJÖKI PROSPECT: http://www.irw-press.com/dokumente/Nortec_140410_EN.pdf
Samples were submitted to ALS Chemex in Outokumpu for Ore grade Au by fire assay and AAS and 48 element acid digestion-acid leach process with ICP-MS or ICP-AES finish.
The previously untested portion of the archived core, which returned the best intercept from the re-sampling programme (5.75g/t gold over 3 metres at a depth of approximately 65 meters) was included in the new assays as a result of Nortec’s recognition of a 3m wide zone of pyrrhotite bearing garnet-hornblende-diopside (“skarn”) greissen rock within the foot-wall mica schist. What makes the discovery of this new zone even more significant is that the mineralisation can be traced a further 500m to the north north-west, as evidenced by drill hole R343, where 4m of 2.69g/t gold was encountered nearer to surface, as a highly sheared, pyrrhotite- and arsenopyrite-bearing silicified zone (“quartzite”) within the feldspar porphyry intrusive host rock.
Nortec Executive Chairman Mohan R. Vulimiri comments, “The location of this new high grade intercept, along with its style of mineralisation should prove to be significant factors in the overall scheme of things at our Seinijoki Prospect. We have essentially discovered a gold-rich greissen or skarn zone over 500 metres in strike and is open at depth. More importantly, from our reconnaissance mapping, we believe that this is part of a stacked sequence of parallel mineralised zones at Marttalanniemi. Identifying this expected style of gold mineralisation associated with sialic intrusive rocks in archive drill core this early in the program adds significantly to the gold potential of the district.”
Mineralisation intersected in drill hole R303 and R307 on the Ylijöki Prospect returned similar grades to that reported by the GTK. Gold mineralisation appears to be controlled by parallel north-west trending shear zones, which can be traced several kilometres and intruded by several feldspar porphyry intrusive rocks and cut by pegmatite dykes.
In 1988, the GTK drilled shallow holes targeting surface geochemical and coincident geophysical anomalies. The holes averaged 50 metres in depth, testing only the top 30 metres below natural surface. The holes rarely intersected the contact between the feldspar porphyry intrusions and the mica schists, a contact zone that is deemed to have greater potential to host gold mineralisation.
Several styles of mineralisation have now been identified within the Seinäjoki Project from both the surface reconnaissance mapping and sampling programme; and, the relogging and re-sampling of the GTK drill core.
These various styles include:-
a)Native GOLD in dacitic to rhyodacitic metavolcanic rocks and graphitic schists, associated with native antimony, minor arsenopyrite and pyrrhotite;
b)Disseminated stratabound antimony-gold mineralization associated with shear zones along contacts between feldspar porphyry intrusions and mica schists;
c)Native GOLD in quartz-tourmaline veins in metavolcanic rocks;
d)Antimony mineralization in pegmatites and metavolcanic rocks;
e)Tin, tungsten, lithium, tantalum, beryllium, niobium and other REE mineralization in pegmatite dykes; and
f)The recently identified high grade disseminated GOLD in pyrrhotite bearing garnet-hornblende-diopside (“skarn”) greissen rock.
Nortec has completed staking over 5,000 hectares in claims within the Seinäjoki district. The Company has begun discussions with drill contractors in Finland with the aim of commissioning an initial exploration drill programme by late April to early May. The drill program will aim to further delineate both the known mineralized zones and the newly discovered high grade gold bearing zones at these two prospect areas, as well as test the surface geochemical and coincident geophysical anomalies below the 50 meter feldspar porphyry contact depth.
