1. Important information
This presentation contains examples of common calculations that can be used to model the businesses in which Boliden operates.
All concentrate specification and contract terms presented here are hypothetical and are used to illustrate the relevant calculations.

3. Pricing of copper concentrates
The price of the raw materials shall be the sum of the values of the payable metals less the sum of the deductions.
In general smelting business consists of the following gross profit elements:
Treatment Charge and Refining Charge for copperRefining Charges for other metalsFree metalsBy product creditsMetal premiums
Boliden Commercial AB 2008-11-046
3.1 Typical pricing clause – Copper
The price of the raw materials shall be the sum of the values of the payable metals less the sum of the deductions.
Buyer shall pay for 96.65% of the final copper content, subject to a minimum deduction of 1.0 unit at the official LME Grade A Settlement Copper Quotation averaged over the quotational period.
Example) For a concentrate with a copper content of 30 % the payable copper value is:
30% x 96.65% x 7,000 USD/t-Cu = 2,030 USD/DMT
Example) For a concentrate with a copper content of 24% the payable copper value is 24% – 1%-unit = 23% i.e. 23/24 x 100 = 95.83% payment:
(24%-1%) x 7,000 USD/t-Cu = 1,610 USD/DMT

3.1 Typical pricing clause – Gold
The price of the raw materials shall be the sum of the values of the payable metals less the sum of the deductions.
Buyer shall pay for 97.50% of the final gold content, subject to a minimum deduction of 1.0 g per DMT, at the London Morning Quotation averaged over the quotational period.
Example) For a concentrate with a gold content of 40 g/DMT the payable gold value is:
40 g/DMT x 0.0321 x 97.50% x 800 USD/troz = 1,002 USD/DMT
Example) For a concentrate with a gold content of 2.0 g/DMT the payable gold value is 2 g/DMT – 1 g/DMT = 1 g/DMT i.e. 1.0/2.0 x100 = 50.0% payment:
(2.0 g/DMT – 1.0 g/DMT) x 0.0321 x 800 USD/troz = 25.7 USD/DMT
Boliden Commercial AB 2008-11-049
3.1 Typical pricing clause – Silver
The price of the raw materials shall be the sum of the values of the payable metals less the sum of the deductions.
Buyer shall pay for 90.0% of the final silver content, subject to a minimum deduction of 30.0 g per DMT, at the London Silver Spot/US Cents Quotation averaged over the quotational period.
Example) For a concentrate with a silver content of 200 g/DMT the payable silver value is 200 g/DMT – 30 g/DMT = 170 g/DMT i.e. 170/200 x 100 = 85.0% payment:
(200 g/DMT – 30 g/DMT) x 0.0321 x 12 USD/troz = 65.5 USD/DMT
3.2 Deductions – Treatment Charge (TC)
TC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
Treatment Charge shall be 45 USD per DMT of concentrate.
Example) 1 DMT Cu concentrate x 45 USD= 45 USD/DMT
TC,RC and Price Participation are negotiated annually between miners and smelters. Typically negotiations start in October and normally finished by year-end. Benchmark terms are normally established when the major mines and smelters have agreed the annual terms.
Boliden Commercial AB 2008-11-0410
3.2 Deductions – Refining Charge (RC)
RC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
The refining charge for payable copper shall be 4.5 USc per pound of payable copper.
Example) For a concentrate with a copper content of 24% the payable copper value is 24% – 1 %-unit = 23%.
23% x 22.046 x 4.5 USc/lb = 22.8 USD/DMT
Boliden Commercial AB 2008-11-0411
3.3 Deductions – Price Participation (PP)
RC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
On long-term contracts there has been a Price Participation clause in the past. i.e. the copper RC shall be increased by 0.10 USc per payable pound of copper for each 1.00 USc per pound which the average LME settlement price for Grade A copper during quotationalperiod exceeds 90 USc per pound payable copper.
Example) An average LME settlement price at 140 USc/lb.
Copper PP: (140 USc/lb – 90 USc/lb) x 10% = 5.0 USc/lbs Copper RC incl. PP: 4.5 USc/lb + 5.0 USc/lb = 9.5 USc/lb
Boliden Commercial AB 2008-11-0412
In recent years the miners have not accepted shown structure for PP in the annual negotiations.
3.4 Deductions – Refining Charge for gold
RC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
The Refining Charge for payable gold shall be 6.0 USD per ounce of payable gold.
Example) For a concentrate with a gold content of 40 g/DMT the RefiningCharge for gold is:
40 g/DMT x 97.50% x 0.0321 x 6.0 USD/troz = 7.5 USD/DMT
Boliden Commercial AB 2008-11-0413
3.4 Deductions – Refining Charge for silver
RC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
The Refining Charge for payable silver shall be 35.0 USc per ounce of payable silver.
Example) For a concentrate with a silver content of 200 g/DMT the payable silver value is 200 g/DMT – 30 g/DMT = 170 g/DMT:
170 g/DMT x 0.0321 x 0.35 USD/troz = 1.9 USD/DMT
Boliden Commercial AB 2008-11-0414
3.5 Deductions – Penalties
TC
The price of the raw materials shall be the sum of the values ofthe payable metals less the sum of the deductions.
For instance, a zinc penalty means that for each 1.0 units by which the final zinc assay exceeds 3.00%, the seller shall pay a penalty charge of 3.00 USD per DMT of concentrates, fractions pro rata.
Example) A final zinc assay of 5.00%, i.e. 2%-units over 3.00%:
2 x 3.0 USD/DMT = 6.0 USD/DMT
Penalty clauses are typically applied for the impurities harmful to copper smelting and refining processes.

4. Pricing of secondary raw materials
In addition to copper concentrate, secondary raw materials can be used as raw material. Secondary raw materials include (among other things):
– Copper scrap– Electronic scrap (containing copper, gold, silver and lead)– Copper/zinc residues
Commercial terms for these materials are constructed and calculated in the same way as copper concentrate but levels of Payment %, TC and RC are not necessary following the copper concentrate terms.Legislations and “green image” are strong drivers to recycle material suitable for a copper smelter.
5. Free metal
Free metal
The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price.
In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.
Example) Value of Free Cu = Cu content x (Recovery% - Payable Cu %) x LME Cu price:
30% x (98.0% - 96.65%) x 7,000 USD/t-Cu = 28.4 USD/DMT

By-product
6. By-product credits
Main by-product for a copper smelter is sulphuric acid (H2SO4)
Example) Value of Sulphur (rule of thumb)= 1 DMT of Cu concentrate with30% of sulphur gives approximately 1 ton of sulphuric acid (H2SO4) depending on recovery rate. Typical recovery rate is 95% in a Cu smelter.
1 DMT Cu concentrate (30%S) x (98/32) x 95% 0.873 ton H2SO4x 75 USD/t = 65.5 USD/DMT
