Eaglecrest Hits Highest Grade Bulk Sample to Date: 11.7 Metres of 10.0 Grams Per Tonne Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 5, 2007) - Eaglecrest Explorations Ltd. ("Eaglecrest", the "Company") (TSX VENTURE:EEL)(FRANKFURT:EAT) is pleased to report that its underground bulk sampling of the L463 shoot has intersected the highest grade interval of bulk sample gold mineralization to date. The exploration program, which consists of surface drilling and underground bulk sampling, is designed to verify the true grade of gold mineralization that is localized in multiple, sub-vertical ore shoots, like the world class gold deposits in Brazil or Ghana. The L463 shoot is the first of four shoots that will be drilled in 2007 in an effort to define a preliminary gold resource for the Dona Amelia zone. While a focused program continues within the 40 square-kilometre Dona Amelia zone, the Company's new geologic and management team continues to generate additional high-quality gold targets on its 300 square-kilometre San Simon project.

Summary of underground bulk sampling results in the L463 shoot.

Length Bulk Sample Gold Grade
Underground Bulk Sample # (metres) (tonnes) (grams/tonne)(i)

Drift L463E, samples 68 - 82, 24.0 319.9 6.5
including, 11.7 151.1 10.0
also. 1.4 19.2 15.6

Drift L463E (entire
mineralized interval) 57.5 819.3 5.9

(i) The Average Gold Grade is a fully diluted milled tonnage weighted
average of the back calculated flotation circuit grade.

"These high gold grades over thick intervals on the eastern side of the L463 shoot are excellent and further justify moving ahead with our more aggressive underground bulk sampling program," comments Eaglecrest's President Hans Rasmussen. "Our bulk sampling program within the L463 shoot will focus on these high grade zones, thus giving us a better understanding of gold distribution. Most importantly, when comparing the gold values above with the thick intervals from our drilling results released on May 8, the volume of gold mineralization that is contained within the L463 shoot has been increased substantially."

The accelerated bulk sampling program will consist of extracting material up dip from the L463-E drift for approximately 50 metres to understand the continuity of gold grade within the high-grade gold zones. The bulk sample material will be processed to generate a gold concentrate. The sales of gold concentrate will partially subsidize the exploration program. With the latest underground development the high-grade gold mineralization in the L463 shoot now has an east-west width of 57.5 metres and remains open to the east where the development of the drift is continuing. The gold mineralization in the L463 shoot also remains open to depth.

Management is encouraged by the similarities being noted at San Simon to that of prominent gold mines in Brazil or Western Africa. The Birimian or Ashanti type gold deposits in Ghana, where past gold production has exceeded 32 million ounces, has gold-mineralization hosted in a shear zone similar to the Main Quartz Vein/Structure (MQV) at San Simon. Ore shoots in these mines have up to 500 metres of vertical extent and 30 metres width, with gold grades that vary from zero to over 30 grams per tonne.

This latest extension of the L463E drift intersected diamond drill hole TRD03-026 (one of the main targets of the underground development), which returned 8.6 grams/tonne gold from over 4.2 metres true thickness. A large bulk sample is now being collected in the location of the drill hole pierce point to compare the underground bulk sample gold grade to the drill hole grade. The development of the L463E drift did not intersect the high grade diamond drill hole TRD06-207, which returned 35.0 grams per tonne gold over 2.6 metres. A 12 metre decline will be developed to bulk sample that drill hole intersection. Underground bulk sample gold results from these drill hole sample points will be combined with results from prior bulk sampling of other diamond drill holes (see April 9, 2007 news release) to provide a more comprehensive comparison of underground bulk sample grades to drill sample grades.

A summary of sample preparation, method of gold analysis and the Quality Assurance/Quality Control (QA/QC) is described in detail in the Company's February 27, 2006 news release.
