Eaglecrest Explorations Ltd.: High Grade Gold Mineralization Extended in Underground Development

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 24, 2006) - Eaglecrest Explorations Ltd. ("Eaglecrest") (TSX VENTURE:EEL)(FWB:EAT) is pleased to report that its underground development and bulk sampling program has extended the zone of known high grade gold mineralization in the L484-W drift in the Trinidad area of the Doña Amelia zone. Bulk sampling of two raises returned fully diluted weighted average gold grades of 6.1 grams per tonne gold over 15.9 metres and 7.2 grams per tonne gold over 6.7 metres.

Results from underground bulk sampling.

undiluted is selectively sampled quartz vein material.

"I believe these results have provided a more accurate gold grade average than had been produced in prior diamond drill testing. Bulk sampling has also helped to confirm the continuity of gold mineralization in the footwall sediments beneath the main structure/quartz vein (MQV)," comments Eaglecrest's Chief Operating Officer Hans Rasmussen. "Footwall mineralization could add substantial volume to the upcoming resource calculation and increase the economic viability of the project. The success of bulk sampling to date at the Dona Amelia zone has left project management with continued confidence in its efforts."

The underground bulk sampling program is designed to test part the drill intersected portions of the MQV as part of Eaglecrest's attempt to achieve an accurate in-situ average gold grade and resource estimate for the Dona Amelia zone. Since Eaglecrest's September 5, 2006 news release three raises and two declines from the L484-W and L484-LR drifts (at 484 metres elevation to the west from the TD-1 decline) have been completed. A map of the underground development on the 484 elevation is located at http://www.eaglecrestexplorations.com/pdf/Underground11222006.pdf.

Footwall Gold Mineralization

1. Footwall (FW) mineralization was described in the September 5, 2006 news release and lies just beneath the MQV mineralization.

2. At the collar of W-R138 raise a pure footwall litharenite sediment bulk sample returned 2.0 grams/tonne gold over width of 2.0 metres.

3. The recent development has extended the FW gold mineralization along the L484-W to 39.9 metres, up to 20 metres up dip in raises LR-R96A, W-R96B and W-R138, and 5.6 metres down dip in the W-D135 decline.

4. Due to FW gold mineralization, which returned up to 14.0 grams/tonne gold in panel samples (10 kilogram sample) in W-R96B, the calculation of undiluted gold grade for the MQV is not possible because the whole advance is mineralized.

The development of the L484-W drifts, raises and declines are continuing concurrently with L463-E drift (463 metres elevation) to the east from the TD-1 access decline. The L463-E drift has reached a length of 72.5 metres in an attempt to intersect up to 10 diamond drill holes including drill hole TRD03-26, which returned 8.6 grams/tonne gold from MQV mineralization over 4.2 metres true thickness.
