Gold Line Resources Ltd. announced its maiden Mineral Resource Estimate ("MRE") for its Kylmäkangas gold deposit, located within the Oijärvi Greenstone Belt, Northern Finland. The MRE for Kylmäkangas is based on 67 historic drill holes totaling 17,678 m, variably spaced from 35 m to 75 m in along an approximately 1.5 km strike. For the deposit, litho-structural, alteration, and 3D modelling of the mineralized zones were prepared using Leapfrog Geo.

Seven (7) separate mineralized lenses were modelled using the alteration zones and a calculated gold equivalent (AuEq) value of 1 g/t. The resource block model was created using Leapfrog Edge software. The block sizes for the resource model were selected to measure 5mx10mx5m and sub-blocked to 0.5mx1mx0.5m minimum height (variable height), based on the basis of drilling density and geometry of the ore bodies. Gold grades were calculated using Inverse Distance-squared interpolation method using hard boundaries around ore zones.

The mineral resources are categorized as Indicated and Inferred based on drill spacing and geological and grade continuity. A maximum distance to the closest composite of 35 m for Indicated and 70 m for Inferred was applied in all zones. The Kylmäkangas gold deposit is a shear zone hosted orogenic gold occurrence.

The deposit is situated within a significant NE-SW striking shear zone along the contact of syn-kinematic altered quartz-feldspar-porphyry intrusions and a folded and altered sequence of mafic and ultramafic mafic volcanic units metamorphosed to upper greenschist facies. The rocks are strongly sheared and foliated, and breccia textures are common. Mineralization consisting of gold, silver and base metals is hosted within massive quartz veins and breccia zones within the shear corridor.

Hydrothermal alteration minerals associated with the gold mineralization includes sericite, biotite, carbonate, and actinolite. Major ore minerals are chalcopyrite, pyrite, galena, tetrahedrite-tennanite, sphalerite and tellurides. The main mineralized zone is located in a dilational jog along the margin of the quartz feldspar porphyry intrusion.

Oblique and extensional veins form stacked en echelon higher grade ore shoots that plunge approximately 20 degrees to the north east from the contact with the porphyry. The tectonic style is brittle-ductile shearing where dilational openings within the shear corridors have been occupied by quartz veins. A less well-defined mineralized zone parallel to the south-east of the main mineralized zone has been identified and will be a target of further exploration work.

In total, seven semi-continuous but separate ore lodes have been identified and modelled along the 1.5 km strike of the mineralization to an approximate depth of 215 metres, but 80% of all contained metal is in lodes 1 and 2. The Oijärvi Greenstone Belt (OGB) is located in the North Ostrobothnia region of northern Finland, in the Ii Municipality and is one of the least studied greenstone belts in Finland. The greenstones of the OGB are situated within the western part of the Meso-to Neoarchean Pudasjärvi complex. Granitoids and gneisses of the Archean tonalite-trondhjemite-granodiorite (TTG) series surround the Oijärvi Greenstone Belt (OGB).

Most of the greenstones are strongly altered and sheared. Bedrock of the OGB is dominated by late Archean greenstones forming a discontinuous belt that measures approximately 80 km in length and varies from 1 to 8 km in width, and branches westwards from the central portion of the belt for 10 km. Age dating on rocks from the OGB yield ages of 2.82-2.80 Ga (Agnico Eagle Finland internal report, 2009), broadly analogous to the age of the Kuhmo, Tipasjärvi and Ilomantsi greenstone belts.

The basic and ultrabasic volcanic rocks of the OGB have been classified as Fe/Mg-tholeiites, Cr-basalts, basaltic komatiites, and komatiites. Komatiitic rocks are mainly located in the southwestern part of the belt (Kylmäkangas area). The regional metamorphic grade in the OGB is mid- to upper greenschist facies, whereas amphibolite facies are more common in the southern extent (Yli-Ii area).

Both extensive and minor shear zones occur within the OGB. The most significant shear zone is the north south striking Karahka Shear Zone where intense deformation and hydrothermally alteration has occurred.
