ORIVESI

Orivesi Gold Mine

The Orivesi Gold Mine is located 80 kilometres northeast of the Vammala Production Centre, within the Tampere Schist Belt. Here, two vertical pipe-like lode systems, Kutema and Sarvisuo occur in strongly deformed, andalusite rich, silicified zones.

All assays have been received from a  45 hole program that was designed to test the Sarvisuo West area between the 480 and 730m levels.  The receipt of a number of promising intercepts, including 2.00m @ 84.13 g/t gold, 4.50m @ 11.58 g/t gold, 8.35m @ 4.67 g/t gold, 1.75m @ 27.16 g/t gold, 3.1m @ 8.33 g/t gold, 2.40m @ 84.53 g/t gold, 3.00m @ 55.10 g/t gold and 1.50m @ 16.23 g/t gold has provided encouragement that Sarvisuo West may represent a new pipe cluster in close proximity to existing underground development. 

A further 11 holes of a 13 hole program have been completed in this area to better define the extent and geometry of identified mineralisation, yielding a best intercept of 3.00m @ 9.72 g/t gold.   

 
Sarvisuo West intercept highlights

A high grade intercept of 20.0m @ 34.67 g/t gold from the upper portion of Pipe 2, was one of several encouraging intercepts obtained from a surface diamond core drilling program that was designed to test the up-dip extensions of the Sarvisuo lode system between surface and the 240m level.

A program of underground drilling from the 260m level to test the up-dip extensions of the Sarvisuo lode system between the 230m and 200m levels has returned a number of high grade intercepts, including 3.80m @ 21.09 g/t gold, 3.00m @ 47.43 g/t gold and 2.15m @ 107.64 g/t gold,  confirming that the  lode system extends to shallower depths.

The potential for the identification of additional pipe clusters similar to the Kutema and Sarvisuo systems, within the hosting hydrothermally alteration zone remains at an early stage of evaluation.

A result of 1.20 metres @ 7.81 g/t gold is one of the more encouraging intercepts obtained away from the mining area. This intercept highlights a narrow zone of gold mineralisation in a previously untested area, 200 metres north of the Kutema Lode System.
