Eaglecrest Announces Improvement of Gold Grades in Underground Bulk Sampling
Program Gold grades higher in new L448E Drift, beneath L463E Drift at San Simon Project
|
VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 28, 2007) - Eaglecrest Explorations Ltd. ("Eaglecrest", the "Company") (TSX VENTURE:EEL)(FRANKFURT:EAT) is pleased to report it has encountered high grade gold mineralization in recent bulk samples taken in the Trinidad area at the San Simon project in Bolivia.
The high-grade bulk samples were extracted from the D206 decline and the new L448E drift, which is located 15 metres beneath the L463E drift and intersected the bottom of D206.
The new results are from Eaglecrest's underground and bulk sampling program at San Simon. Both the L463E drift and the L448E drift cut the upper part of the new L463 high grade gold shoot.
"The bulk sampling results from the Trinidad area are very promising," said Hans Rasmussen, President of Eaglecrest. "We are finding that bulk samples in the new L448E drift verify higher grades below the L463E drift, as were indicated by our detailed drill hole results. The bulk samples represent vein and immediately adjacent wallrock, and our drilling has indicated potential for additional footwall and hanging wall mineralization as well as multiple, stacked mineralized zones. These consistently high gold grades are encouraging and the objective of our current drill program is to outline similar mineralization in the L484 gold shoot to the west."

and mill feed grades determined for the individual bulk samples or
rounds.Technical Discussion
The underground bulk sampling program was designed to determine accurate in-situ grades in portions of the mineralized main thrust fault structure in the Dona Amelia zone.
Raises in the table (above) were driven upward from the L463E drift and along the dip of the mineralized structure. They were designed to understand gold grade distribution and test underground mining techniques in the upper part of the L463 shoot. Each length interval shown in the table incorporates various blast rounds or bulk samples, as indicated. The reported gold grades are the tonnage-weighted average of the bulk samples.
All bulk samples were processed at the Company's onsite bulk sampling plant. A total of 8,746 tonnes have been processed from the L463E drift, raises, decline, T2 ramp, and L448E drift to date.
