Mr. David H. Brett, President and CEO, Pacific Bay Minerals Ltd. (TSX
VENTURE:PBM) (the "Company" or "Pacific Bay"), reports soil and rock samples
strongly anomalous in Rare Earth Elements ("REEs") from the Company's 100% owned
Cueva del Chacho Property in La Rioja province, Argentina, with values up to 832
ppm Cerium and 338 ppm Lanthanum. A follow up program of sampling and mapping is
planned for March 2010.


The strongly anomalous samples were taken in 2006 over zones of elevated
radioactivity in an area of poor outcrop exposure during a uranium exploration
reconnaissance program. Most of the radioactivity was determined to be caused by
Thorium, but the two REE results included in the multi-element analysis package,
Lanthanum and Cerium, were not reviewed at the time. In view of the newly
increased interest in REEs, Pacific Bay is launching further investigation of
the property.


The Cueva del Chacho property is located approximately 70 km south-southwest of
the provincial capital city of La Rioja adjacent to a major paved road. The
3,000 hectare (11.5 sq mi) Cueva del Chacho property lies on-trend, 8 kms north
of the Los Colorados Mine, on a regional sedimentary reduction-oxidation
boundary where approximately 55,000 kg of uranium concentrates were produced
from classic sedimentary roll-fronts between 1992 and 1996.
