Eaglecrest Explorations Ltd.: Portal for the TD-1 Decline Shaft Collared.

VANCOUVER, British Columbia -- Eaglecrest Explorations Ltd. (TSX VENTURE:EEL)(FWB:EAT.FSE) is pleased to report that the underground development contractor AMTRAC Ltda. has mobilized equipment and personnel for development of the decline shafts in the Trinidad area (TD-1) and Manganeso area (MD-1) to the Dona Amelia zone. Both declines are within the Dona Amelia zone that covers an area of 40 square km within the Company's 298.84 square km San Simon project in northeast Bolivia. Collaring of the TD-1 decline shaft was started with the first round on July 29, 2005.

AMTRAC Ltda.'s mining engineer, shift bosses, personnel, construction material and mining equipment (scoop tram/LHD, compressor, jack legs etc.) have been arriving on site over the past two weeks. Constructions of surface support facilities and infrastructures have been ongoing concurrently with clearing of the actual portal area. The initial rounds of the portal was a partial profile of the full decline shaft profile and have been followed by two additional rounds on a daily basis (AMTRAC is currently running one shift only). As of July 31, 2005 the TD-1 decline shaft had reached a length of 4.0 metres (m) with a face exposure of 2.4 m (0.6 m short of the full face profile). The main quartz vein/structure (MQV) has a width of 1.5 m in the last face of the portal development. Additional advances are required before the brow of the portal will be established and the portal timbers can be installed.

Surface mapping in the Trinidad area and interpretation of existing diamond drill hole data including the decline shaft pilot holes have defined the MQV as a folded anticinorium with wave length of 80 to 100 m between pares of anticlines. The maximum dilation is along the syncline hinge zones with the minimum dilation along the anticline hinge zone. The hinge zones are plunging down dip at N130E or 50 degrees of the dip direction.

The TD-1 decline shaft in the Trinidad area has been redesigned to follow a syncline hinge zone down plunge from the collar rather than straight down dip oblique to the hinge zones. This will allow for maximum MQV width within the decline shaft. The profile is 3.0 by 3.0 m with a slight curve of the back for added strength and security. The incline shaft will be collared at a 25 degree slope which will increase to a maximum of 40 degrees before it reaches its target depth 146 m below portal elevation after 255 m of development. A 20 m addition to the decline shaft along the down plunge extension of the MQV will serve as a sump during the simultaneous development of two drifts (2.5 by 2.5 m profile)along the MQV to the west (200 m) and to the east (100 m) to selected drill hole intersections of the MQV and explore the width variations across the anticinorium.

Total development of the TD-1 is 520 m that will produce an estimated 10,000 tonne of ore to be trucked 8.2 km to the gold recovery plant in the Manganeso area where it will be processed through the plant in batches to determine the true in-situ gold grade of the MQV in the Trinidad area. The gold recovery plant is anticipated to produce approximately 50% flotation gold concentrate and approximately 50% jig plus table concentrate with estimated 50% gold bullion for an overall gold recovery estimated at 95%. Both concentrates will be sold to an international smelter. The TD-1 decline shaft is scheduled to be completed in early December 2005.

Surface installation for the MD-1 decline shaft will initiate in the final stages of the TD-1 development so collaring of this decline shaft can be done immediately subsequent to the completion of TD-1 in December 2005. The MD-1 is scheduled for completion in March 2006.

The underground exploration development and bulk sampling program is being supervised by Tor Bruland, P. Geo. and Don Allen, P. Eng., both of whom are Qualified Persons under the Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects.
