Vancouver-based junior Blue Desert Mining (BDE-A) continues to outline a copper deposit at its Enero property in central Chile, 150 km north of Santiago.
Geophysical work on the newly discovered Mulas zone has enabled the company to extend the target area to the north, south and east.
The Mulas zone consists of porphyry copper mineralization in a diorite intrusive adjacent to altered volcanic rocks. Initial soil and rock sampling has revealed strongly anomalous copper over a 1,500-by-600-metre area. Where the zone is exposed in outcrop, chip samples have returned values of up to 1.48% copper, 0.45 gram gold and 10.3 grams silver per tonne over 50 metres.
A large chargeability anomaly occurs over an area measuring 2,000 by 1,400 metres. The western portion of the anomaly is coincident with the copper soil anomaly covering Mulas. Shallow high-chargeability values extend a further 300 metres northward and 800 metres eastward, into soil-covered areas of the Rio del Sobrante Valley.
A separate chargeability anomaly, also associated with copper mineralization, lies west of Mulas and trends north-south for more than 1,800 metres.
Blue Desert states that these geophysical results confirm the multi-million-tonne potential of the copper deposit.
Meanwhile, other exploration work is in progress. About 470 soil samples taken from the expanded grid are being analyzed, and mapping and sampling are under way at the Honda zone, where 1% copper was found in samples from a diorite intrusive, and at the Chincolco zone on the Nuevo Ano property to the south of Enero.
Blue Desert points out that the Enero property lies within a copper belt that contains several substantial porphyry copper deposits, including Los Pelambres (3.3 billion tonnes grading 0.63% copper and 0.016% molybdenum) and Andina and La Disputada (combined reserves of 2 billion tonnes at 0.81% copper and 0.016% moly).
