SIGNIFICANTLY EXPANDED MEASURED AND INDICATED MINERAL RESOURCES AT TAIVALJÄRVI SILVER MINE - UPDATED FEASIBILITY STUDY WILL BE READY DURING Q1/2012.
Sotkamo Silver is pleased to announce an update of the Mineral Resources at the Taivaljärvi Silver Mine. The updated Mineral-Resources are based on the 2011 completed core-drilling program and have been estimated in accordance with the guidelines of the JORC Code (2004).
Based on these figures an updated Feasibility Study can now be completed during first quarter of 2012.
The amount of Measured and Indicated Mineral Resources have increased by 58%, in terms of tonnage, or 60% in terms of amount of silver-equivalents in these categories, using a cut-off 50g/t AqEq. The deposit is open at depth and the geological formation continues below a depth of 550 m.
Resources estimated and reported herein are based on the Resource model produced by Dr. Parkkinen, but have been audited and reviewed by Wardell Armstrong International (WAI) in the fourth quarter of 2011 and takes into account material extracted at the Taivaljärvi deposit up until 14 December 2011.
Total Mineral Resources as of 14 December 2011 for the Taivaljärvi Silver Mine are shown in the table below at a 50g/t Ageq cut-off grade (COG).

Modelling of the mineralisation has been carried out based on a silver metal equivalent (Ageq). The parameters used to derive the Ageq are shown in the table below with the equivalent factors derived using the formula:
eq Factor= (metal unit price*(metal recovery/100))/(Ag unit price*(Ag recovery/100))
The actual Ageq values were calculated into the drill hole database and the subsequent block model based on the formula:
Ageq=Ag+(Au*Au factor)+(Pb*Pb factor)+(Zn*Zn factor)
Sotkamo Ag Equivalent Parameters | ||||
Metal | Metal Price (US$) | Recovery (%) | Unit Price (US$) | Metal Equiv Factor |
Ag | 28/Oz | 85 | 0.90/g | 1 |
Au | 1,200/Oz | 90 | 38.58/g | 45.38 |

Zn | 2,100/t | 85 | 21.00/% | 23.33 |
“I am very pleased with these excellent results. The significant increase in the Measured and Indicated Mineral Resources means that Taivaljärvi Silvermine's Feasibility Study calculations can now be completed and I expect that it will be ready during first quarter of 2012." says Timo Lindborg, CEO of Sotkamo Silver AB.
