LONDON--Mariana Resources Ltd (MARL.LN), an AIM-quoted exploration and development company focused in Peru and southern Argentina, Tuesday announced further positive results from its 2000 meters drill campaign at the copper-gold-silver Soledad prospect in Peru.

First half of the program has confirmed strong mineralization extending over a 1 kilometer diameter between Breccia 1 and the previously untested Breccia 5, 6 and Cima Blanca targets.

Chief Executive Officer, Glen Parsons said: "Results of mineralization from the first half of the program have been extremely encouraging with centers of mineralization at Breccias 1, 5, 6 and Cima Blanca occurring within a 1 kilometers square area.

"The new target areas specifically Breccia 5 and 6 have yielded further strong mineralization within the pipes, which along with results from Breccia 1 enhances our overall geological model considerably."

Mr. Parsons said the company is now completing the drill program by targeting deeper breccia pipe levels and adjoining potentially mineralized intrusive porphyry at depth.

Shares at 0800 GMT traded up 5.7%, at 3 pence, valuing the company at GBP13.8 million.
