Edited Press Release
LONDON (Dow Jones)--Vane Minerals said Wednesday that for its interim results for the six months ended June 30 it made a pretax loss of GBP0.729 million compared with a loss of GBP0.968 million.

Steven D Van Nort, Chief Executive, said the company continues to utilise cash flow from Diablito to expand and diversify our exploration portfolio.

The company's joint venture with U1 not only attests to its technical expertise but also enhances its chances of success. In addition, it anticipate that the active drilling programme scheduled for the second half of 2008 will generate positive news flow.

In summary, your company continues to enjoy a healthy financial position, aided by production/cash flow from our Diablito/SDA operations.

The joint venture with U1 on the south rim projects is an important step forward for the company and the Board is particularly looking forward to building on this relationship in the future.
