Pursuant to the terms of the Option, Zodiac will incorporate and fund a Mexican subsidiary ("Zodiac Mexico") that will earn a 90% interest in the Property over a three-year period in consideration for total cash payments of US$500,000. Zodiac Mexico will be required to perform a minimum of US$1.5 million in exploration expenditures on the Property over the three-year term of the Option. The remaining 10% interest in the Property will remain with Arco as a carried interest. Zodiac may elect at any time during the term of the option to purchase Arco's 10% carried interest in the Property for US$1,000,000. In addition, Arco will receive shares of Zodiac Mexico, having a value of US$250,000, concurrent with Zodiac Mexico's listing on the Australian Stock Exchange or such other stock exchange as Zodiac may determine. Finally, Arco will receive a 1% net smelter royalty on any production from the Property.

Tres Hermanas Property

The Property consists of the Tres Hermanas 1 and Tres Hermanas 2 claim blocks, which have areas of 500 and 900 hectares respectively, and the Khulan claim block of 2310 hectares.

The Tres Hermanas property covers a silver-lead-zinc-bearing vein system that has historic underground workings on five levels along a 400 metre strike.
