Jokisivu Gold Mine
The Jokisivu Gold Mine is located 40 kilometres south west of the Vammala Production Centre and hosts a Measured, Indicated and Inferred Resource totalling 339,400 ounces.
Mineralisation in the Kujankallio area extends to at least 525 metres vertical depth, though resource drilling currently extends only down to 440 metres, whilst in the Arpola area mineralisation has only been drilled down to 200 metres. Both areas remain open at depth, partially along strike and may link.
Jokisivu became Dragon Mining’s third operating mine in 2009, and since commencement, 207,425 tonnes of ore mined have been mined and transported from Jokisivu to Vammala.
Jokisivu Gold Mine Layout
The underground development at Kujankallio commenced in September 2010 and since then, the decline had advanced 1,378m or 210m in vertical depth. The portal is located within the Kujankallio open pit, 35m below surface.
In 2011, 3,000m of lateral development from 5 levels (65m, 85m, 105m, 145m and 175m) was completed. Mining of stopes at the 85m and 145m levels continued. The first stoping ore was delivered in January with 3,849 tonnes at an average grade of 3.1 g/t gold processed.
9,566 tonnes of development ore grading 3.9 g/t gold and 20,451 tonnes of Jokisivu open pit ore at a grade of 3.3 g/t gold were also processed during the March quarter.
An internal assessment will be made to determine if it is viable to extend underground mining to the Aprola area where an Indicated and Inferred Resource of 87,300 ounces grading 6.5 g/t gold remains.
