 Eaglecrest
resumed exploring the gold mineralization in the Doña
Amelia zone in July 2003. The Company drilled 2,024 m in 25
holes in the Doña Amelia Zone gold mineralization in
1996, but between 1997 and 2002 the Company focused exploration
on the potential for open pit mineable gold mineralization
in the Paititi zone. In October 2003 the Company commenced
drilling three north-south sections in the Trinidad area,
which have provided promising diamond drill core results.
Drilling continues in the Trinidad area. The Western part
of the Thrust fault was drilled in the Manganeso area in 2003-2004.
The Company returned to focus on the Trinidad area in 2005
and continues presently.
To date the Company has drilled more than 70,000 m in 300
holes with up to 4 core diamond drills; currently 2 diamond
drills are actively drilling on 24-hour shifts on the property.
Highlights of the exploration program include:
- In January 2007, the company announced it had modeled
drill hole assay results in the Doña Amelia zone,
and that ore-grade gold is most likely localized in pods
or shoots like the ore deposits in the Birimian Belt of
Ghana where mines like Ashanti have produced millions
of ounces of gold.
- In May 2007, Eaglecrest announced that infill and delineation
drilling of the L463 shoot intersected high grade gold
values – thus validating the new drill program.
Highlights included: 10.1 metres of 3.0 grams/tonne gold,
including 1.0 metre at 27.5 grams/tonne gold from hole
229; 8.0 metres with 9.0 grams/tonne gold, including 0.9
metres at 59.1 grams/tonne gold from hole 237; and, 8.0
metres with 4.0 grams/tonne gold, including 0.5 metres
at 26.5 grams/tonne gold from hole 235.
- In late September 2007, Eaglecrest announced the highest
grades and most consistent drill results in the 11-year
drilling history at San Simon from the infill and delineation
drilling of the L463 shoot in the Doña Amelia zone.
Highlights included 3.5 metres at 15.8 grams/tonne gold
from hole 259; 5.2 metres at 9.4 grams/tonne gold from
hole 257; and 4.4 metres at 11.5 grams/tonne from hole
268. From the inception of the infill drilling program
in early 2007, one third of the drill holes returned intervals
of greater than 10 grams/tonne gold. Management considers
these results significant for justifying continuing the
infill drilling program.
The company initiated an underground bulk sampling program
in August 2005 to determine the in-situ true gold grade of
the quartz vein mineralization by developing the TD-1 decline
in the Trinidad area. The purpose is to bulk sample selected
diamond drill hole intersections to compare drilled gold grade
with bulk sample gold grade. The decline is developed down
plunge in the MQV. Underground panel sampling was done on
each advance which is subsequently bulk sampled for the in-situ
gold grade.
By the end of April 2007 the TD-1 decline had reached a length
of 150 m. Additionally, two large drifts, called L484W and
L463E have been completed off the main decline. From these
drifts multiple raises and declines have been completed in
an effort to both test bulk sample gold grades at drill hole
intersections, and to test various small-scale mining techniques
for later scoping studies of underground mine models. Significant
results include the following:
- In June 2007, Eaglecrest announced that underground
bulk sampling of the L463 shoot intersected the highest
grade interval of gold mineralization to date; 57.5 metres
of 5.9 grams/tonne gold. Within this interval, 151 tonnes
were extracted from a length of 11.7 metres in the L463
drift and averaged 10.0 grams/tonne gold.
- In late November 2007, Eaglecrest announced the highest
grades from the underground bulk sampling program; high-grade
bulk samples were extracted from the D206 decline and
the new L448E drift, which is located 15 metres beneath
the L463E drift. Both the L463E drift and the L448E drift
cut the upper part of the new L463 high grade gold shoot.
From the L448E drift, 44.0 metres of 7.0 grams/tonne gold,
including 12.7 metres averaging 12.0 grams/tonne gold.
Additionally, the sampling of the D206, a bulk sample
of 10.5 returned 7.9 grams/tonne gold.
Eaglecrest has installed a standard Fire Assay laboratory
adjacent to the camp. The lab is independently operated by
Peruvian ANALAB S.R.L. and has a capacity of 48 hours turn-around
time for sample results to allow for a timely calculation
of metallurgical balances and bulk samples gold grades. The
laboratory was designed and is supervised by Mineral Processing
