In early April, the company said it had optioned more than half of its joint venture Axe property in British Columbia to Xstrata Copper Canada, a unit of Xstrata (LON:XTA), the world's fourth largest copper producer.
The Axe property is an advanced stage project with known porphyry copper mineralization, which has been drill tested several times since the 1960s. The project is comprised of 25 mineral claims, or 4,983 hectares, located in the Similameen Mining Division, 20 kilometres north of Princeton in British Columbia.
Weststar remains focused on its La Paloma property in the state of Jalisco, Mexico, where in February it announced the completion of an induced polarization/resistivity survey. It also started the planning for the upcoming diamond drill program at the site.
The property is located approximately 70 kilometres west of the city of Guadalajara.
The IP/Resistivity survey at La Paloma consisted of a total of 5.8 line-kilometres, which were surveyed along a series of seven lines targeting an 800 metre strike extent of the Main "Piedra Bola" Vein structure.
Shares of the company are currently trading around 12 cents.
