The company
was established on April 10, 1981 with original registered capital of Bt20 million

operations with the objective of producing zinc metal and zinc alloys to satisfy customer
demand. The company’s mine is located in Mae Sot district, Tak province, which
borders Myanmar. The smelter is located in the city of the same province. The roaster
plant is located in Rayong and the company’s head office is in Bangkok. The company
has also engaged in zinc ore exploration programmes in Thailand and in neighbouring

| General |
Since 1995, Padaeng Industry has imported zinc
sulphide as a feedstock for the refinery. Because of its slightly different properties,
zinc sulphide must first be roasted to form the oxide “calcine” before the zinc
can be extracted.
The
company has converted its operations to include a facility to produce zinc oxide
(calcine). This facility is located on the grounds of the Padaeng Industrial Estate at Map
Ta Phut in Rayong province on the eastern seaboard of Thailand, which began operations
mid-1995. Zinc sulphide is converted into calcine during the roasting process, while the
sulphur constituent is converted into saleable sulphur acid. The calcine is then delivered
to the zinc smelting plant in Tak province. |

April 4, 2008 - Nyrstar NV (“Nyrstar”),
the world’s largest producer of zinc metal and alloys, today announced that it has
reached agreement to divest its 24.9% minority shareholding in Padaeng Industry Public
Company Limited (Padaeng) to a consortium of investors, represented by Asia Plus
Securities Public Company Limited, for €34 million in cash. The shareholding had a book value of €50
million at 31 December 2007, which was based on Padaeng’s share price at the time
Nyrstar was established. Accordingly, and based on the current exchange rate, the
transaction will result in a loss of €16 million, reflecting the decline in Padaeng’s
share price since 31 August 2007 as well as the decrease in the value of the Thai baht
against the Euro. Umicore SA/NV, one of
Nyrstar’s founding shareholders, also announced that it has divested its 22%
shareholding.
Padaeng, listed on the Stock Exchange of Thailand, operates a silicate zinc mine and a
smelter in Tak province, as well as a roaster plant located in Rayong province. Production
of zinc metal and alloys is focused on the domestic Thai market.
Nyrstar felt that its minority investment in Padaeng, without the potential for
operational control, meant that it was a non-core asset. Any increase to Nyrstar’s
holding reaching 25% of the total voting shares in Padaeng would have resulted in Nyrstar
being required to launch a mandatory tender offer for all outstanding shares. However, due
to Thai regulations restricting foreign ownership of natural resource assets to less than
50%, Nyrstar would have been precluded from acquiring control of the business. “Our minority interest in Padaeng meant we
had limited influence over the company and due to Thai regulations would not have been
able to secure control. Our decision to sell releases additional capital that can be
better deployed elsewhere.” said Paul Fowler, chief executive officer of Nyrstar. |
