Avalon Minerals – Background

Avalon Minerals Ltd listed in March 2007 with the aim of developing and discovering mineral deposits.

Avalon’s corporate objective is to build a diversified resource mining group based on cash flows from producing operations.

The primary project generation strategy has been successful with the acquisition of the advanced Viscaria copper deposit in northern Sweden where a maiden JORC Code compliant copper resource has been defined. This resource comprises of an Inferred Resource of:

8.2 million tonnes grading 2.7% Cu for the ‘A’ Zone South;

5.6 million tonnes grading 1.3% Cu for the ‘A’ Zone North; 24.3 million tonnes grading 0.8% Cu for the ‘B’ Zone; and

2.5 million tonnes grading 1.6% Cu for the ‘D’ Zone.

When combined, this totals 520,000 tonnes of contained copper.

In addition the recently acquired cluster of five closed historical copper- zinc mines at Adak, 300km south of Viscaria, also provides potential for Avalon to grow its base metal inventory within northern Sweden.
